The invention relates to an electrical contact coupling to the stele of the vehicle, in particular for a rail vehicle.

Electrical contact couplings are typically used in the field of rail vehicles for the transmission of control signals and energy between adjacent bodies of multibody vehicle. The device management and the size of the used electrical contact couplings depend on the space available in the vehicle, and the number of signals that should be transmitted, as well as the requirements of the manufacturer of rail trucks and/or rail operator.

Electrical contact coupling is usually performed so that two electrical contact coupling could be linked and be split automatically. With this purpose, the electrical contact coupling to be installed on the clutch vehicles or bodies, just connect to each other by means of a centering device and then sealing surfaces formed on the pinned along the end surfaces of the electrical contact coupling in order to achieve reliable sealing from the environment. In rosapenna position protective hinged cover closes the end surface of the electrical contact coupling, h is usually used to protect the elements of the coupling or existing contact elements of the electrical contact coupling, there can be, from contact and contamination.

For example, in the printed publication DE 938915 AS described electrical contact coupling for railway vehicles for connecting electric lines and signal lines. Such electrical contact coupling includes a clutch housing, which must be attached to the body of a rail vehicle, the said case is made with the possibility of placing elements and contacts of the coupling and the presence of holes of the coupling on the end surface. The hole of the clutch can be closed protective hinged cover mounted on the housing to be rotated from the closed position to the open position.

More precisely, in the known solution uses a relatively complex mechanism consisting of a set of articulated levers and points to rotate the protective flip cover relative to the housing of the coupling.

To simplify the mechanism for turning the hinged protective cover, in principle, it is possible to attach the protective flip cover to clutch housing, using a simple hinge so that the protective flip cover could be rotated about a fixed axis of rotation. However, the use of simple hinges for folding protective hinged cover has the disadvantage that when the protective from Edna cover is in the closed position, the contour of the cover does not sit completely hard on the sealing surface of the clutch housing, respectively, the sealing surface of the front body frame coupling, and thus the effective sealing is usually impossible, in this respect, the main problem are the side clearances under the seal between the protective hinged cover and clutch housing. Appearing thus lateral cracks, when the protective flip cover is in the closed position, can prevent dust, especially metal dust, and moisture that can lead to a reduction in the surface resistance. Also can get abrasive dirt particles, causing increased wear of the electrical contacts.

If you are using additional sealing gasket for sealing the lateral clearances under the seal between the protective hinged cover and clutch housing, the frictional force acting on the lateral sealing elements cannot be eliminated, when the protective flip cover is open or closed, which leads to increased wear of the lateral sealing elements.

The invention is based on the task of creating an electric contact coupling with protective flip cover, is able to rotate relative to the clutch housing using a simple mechanism, which, however, provide the t large sealing against dust and moisture, in order to reduce maintenance costs, and use the elements of the coupling for optical data transmission.

This problem is solved in accordance with the invention the essence of independent claim 1.

In accordance with the electrical contact coupling includes a housing having a hole made in the end surface of the housing, and a sealing gasket at least partially covering the opening in the housing. Additionally, protective flip cover, which is pivotally attached to the clutch housing to the protective flip cover can rotate relative to the clutch housing around a fixed axis of rotation from a first position in which the opening in the housing is closed, a second position in which the bore in the housing is open. In accordance with the invention, the gasket has an upper sealing region, the ongoing predominantly parallel to the axis of rotation, and the lower sealing region, the ongoing predominantly parallel to the axis of rotation. Protective flip cover has a contact area which is in contact with the sealing gasket to seal the clutch housing at the first position of the protective hinged cover. Part of the contact area of the protective hinged cover, which comes in contact with the top o of the sphere at the first position of the protective hinged cover, made in the form sealing surfaces, oriented mainly perpendicular to the end surface of the housing. In contrast, the area of contact of the protective hinged cover which is in contact with the lower sealing area when the first position of the protective hinged cover, made in the form sealing surfaces, oriented predominantly parallel to the end surface of the body.

In one preferred embodiment, the solution in accordance with the invention, the gasket has an additional side sealing region, which connects the upper sealing region with the lower sealing area, and the area of contact of the protective hinged cover which is in contact with the side sealing region at the first position of the protective hinged cover, made in the form of a three-dimensional sealing surface. Side sealing region at the area of contact of the protective hinged cover, made in the form of a three-dimensional sealing surface, continuously connects the sealing surface, oriented mainly perpendicular to the end surface of the housing, with the sealing surface, oriented predominantly parallel to the end surface of the body.

In this regard, the sealing gasket, in particular, can be made in the form of an annular sealing gasket, which, thus, in addition to the upper and lower sealing areas, has two side sealing region, made mirror-symmetrical to each other, and each area respectively connects the upper sealing region with the lower sealing area. In order to achieve optimal sealing of the lateral clearances under seal in the closed position, the hinged protective cover, it is envisaged that each area of the contact area of the protective hinged cover which is in contact with one of the two side sealing regions when the first position of the protective hinged cover, was made in the form of a three-dimensional sealing surface, which continuously connects the sealing surface, oriented mainly perpendicular to the end surface of the housing, with the sealing surface, oriented predominantly parallel to the end surface of the body.

The benefits that can be achieved with the solution according to the invention, is obvious. As protective flip cover is rotated relative to the clutch housing around a fixed axis of rotation, does not require a complicated mechanism for turning the protective hinged cover. Instead, protective from Edna cover may be attached to the clutch housing by means of a simple hinge. As there is no need to use complex articulated structures, such as the four-tier system, etc. for turning a protective hinged cover, the electrical contact coupling can be performed in a more simple design in General, and, therefore, more economical and compact.

On the other hand, the solution according to the invention provides that the protective flip cover contained a contact area in contact with the sealing gasket attached to the end surface of the housing, respectively, the front frame of the housing, for sealing the clutch housing at the first position of the protective hinged cover. To this end, the contact area of the protective hinged cover; that is, the area of protective hinged cover, which comes in contact with the sealing gasket for sealing the clutch housing in the first (closed) position protective hinged cover, made from a variety tangentially transition areas. And that is the area of the contact area which is in contact with the upper sealing area of the gasket when the first position of the protective hinged cover, made in the form sealing surfaces, oriented mainly perpendicular to the end surface of the housing. In other words, the area of the contact area associated with the upper uplotnitel the second region, comes in contact with the sealing gasket at the top when the electrical contact coupling is in the closed position.

In contrast, the area of the contact area which is in contact with the lower sealing area of the gasket when the first position of the protective hinged cover, made in the form sealing surfaces, oriented predominantly parallel to the end surface of the housing, so that the area of contact is mated with the lower sealing area that was in contact with the sealing gasket from the front, when the electrical contact coupling is in the closed position.

In order to be able effectively to seal the side clearances under the seal gasket between the upper and lower sealing areas at the closed position, the electrical contact coupling, the invention provides that the sealing gasket is additionally contained side sealing region for connecting the upper sealing region with the lower sealing area. The contact area of the protective hinged cover is mated to the site corresponding to the side of the sealing region which is in contact with the side sealing region when the protective flip cover is in the first position. To prevent friction the area of the contact area, paired with a side of the sealing area on the side of the sealing region when the electric contact coupling is open; that is, when the protective flip cover moves from the first (closed) position to the second (open) position, according to the invention provides that the area of the contact area associated with the side sealing region, was made in the form of a three-dimensional sealing surface, which continuously connects the sealing surface, oriented mainly perpendicular to the end surface of the housing, with the sealing surface, oriented predominantly parallel to the end surface of the body.

Three-dimensional sealing surface is made so that none of its regions not facing side of the sealing area of the gasket to the end of the closing of the hinged cover, preferably, not until the last 5 degrees of the closing of the hinged cover, and therefore, friction is obtained minimal.

As mentioned above, the area of the contact area associated with a lateral sealing area which is in the form of a three-dimensional sealing surface, which continuously connects the sealing surface, oriented mainly perpendicular to the end surface of the housing, the sealing surface is stew, oriented mainly parallel to the end surface of the housing. Therefore, the area of contact made in the form of a three-dimensional sealing surface is formed in the area of the sealing surface mating with the upper sealing area to make radial contact transversal sealing area outside the mentioned areas. Then again, the area of contact made in the form of a three-dimensional sealing surface is formed in the zone of the lower sealing area to the side of the sealing region contacted the front.

Here it should be noted that here the direction indication "upper" and "lower"do not depend on the positional orientation of the electrical contact coupling. Display areas are the provision of a protective hinged cover in the open position. Regardless of the orientation of the electrical contact coupling the indication "top" here indicates the direction in which the protective flip cover is rotated relative to the clutch housing when opened. Display "lower" is used to indicate respectively the opposite direction. Additionally, the indication "front"used here should be understood as the direction opposite to the direction of the clutch.

In order to achieve full Hermetists and electrical contact coupling in the closed position, the gasket is preferably made in the form of an annular sealing gasket that completely covers the bore of the housing, is made on the end surface of the housing. This annular sealing gasket may be made in the form of a sealing ring made of elastomeric material, which is therefore intended and for axial (front) and radial (outside) load.

The electrical contact coupling 100 shown in the drawings as an option, are designed to attach to the stele vehicle, in particular a railway vehicle, so that the end surface And the housing of the electrical contact coupling 100 has been turned in the direction L of the clutch with the vehicle and was in the plane M of the clutch or could be introduced in the plane M of the clutch. Moreover, the electrical contact coupling 100 is used in connection with the electrical contact coupling 100', made an addition to it (see Fig.6), to establish the connection between electr the ical lines and/or signal lines between two adjacent vehicles, in particular, the railway means of transport.

From perspective images with a spatial separation of the components presented in figure 1, the electrical contact coupling 100 in accordance with the variant has a trapezoidal enclosure 1, in the lower part or base 10 (6) which can be installed bushings (not shown) for the movable mounting of the clutch housing 1 in the direction L of the clutch with the vehicle, in particular rail vehicles on rails (also not shown). Thus, the end surface And the housing of the electrical contact coupling 100 may not be entered in plane M of the clutch until, for example, completed mechanical coupling of neighboring vehicles. Therefore, when this will prevent damage to the electrical contact coupling when the vehicle subject to seizure, are approaching each other.

Moreover, it is possible to provide for centering elements on the body 1 of the coupling, for example, in the form of the centering pins and the corresponding optionally performed centering bushings to align the subject to grip the electrical contact coupling 100, 100', when vehicles are approaching each other.

As shown in figure 1, the body 1 of the coupling to depict ablanovo option has a predominantly rectangular interior space, in which you can place the coupling elements, respectively, the contacts of the electrical contact coupling. Hole 2 of the housing facing in the direction L of the clutch, made in the end surface of the housing 1 And the clutch.

In the present embodiment, the electrical contact coupling 100 according to the invention the hole 2 of the housing is completely surrounded by a sealing gasket 3. As shown in figure 1, the gasket 3 has a shape corresponding to the outer contour of the housing 1 of the coupling, so that the gasket 3 has a trapezoidal shape. Seal 3 removable attached (it is unclear visible) to the front frame of the housing 1. Also the gasket 3 may contain grooved section 8, which can be seen from the form in the section in Fig.5b. This mainly U-shaped grooved section 8 of the gasket 3 can directly be connected (not shown in the drawings) with a projecting part of a front body frame. When this sealing gasket 3 can be easily removed from the housing 1 in the event replacement is necessary during the maintenance work, etc.

From Fig.5b can additionally be noted that the gasket 3 has a protruding portion 9 connected to the grooved section 8. This protruding part 9 is partially circular in cross section. Vystupaya the part 9 is turned in the direction L of the clutch at a fixed position of the sealing strip 3 on the end face And body, so that, as seen from the front and from above, respectively, radially outward of the sealing region 3A, 3b, 3C, 3C', used to seal the housing 1 coupler, were rounded, which allows you to load a sealing gasket 3 and the axial (front), and radial (outside).

But also, of course, possible to use an annular sealing gasket of circular cross section (ring)attached to the end surface of the housing 1 And the clutch.

The electrical contact coupling 100 according to the embodiment represented in the drawings, includes protective flip cover 4, which is pivotally attached to the body 1 of the coupling by means of two lateral hinges 6 swivel type protective flip cover 4 could be rotated relative to the body 1 of the coupling around a fixed axis R of rotation from a first position in which the opening 2 in the casing is closed, a second position in which the opening 2 in the casing open. You can use the appropriate drive 7 for turning the protective hinged cover 4 around the axis R of rotation. But also, of course, can mechanically rotate protective flip cover 4 relative to the body 1 of the coupling, using a spring or other means.

In particular, from the view presented on Fig.6, we can see that a simple hinge 6 swivel type uses the I for turning the protective hinged cover 4, mentioned hinge 6 swivel type connects the protective flip cover 4 with the pivot point through which the axis R of rotation extends through a simple hinge arm. Protective flip cover 4 has a rounded inner circuit to turn on the upper edge of the hull.

The interaction between the protective flap 4 and the gasket 3, attached to the end surface of the housing 1 And the coupling will be described in more detail below with reference to figures 2, 3 and 4. Option electrical contact coupling 100 in accordance with the invention, shown in partial section in figure 2, while the protective flip cover 4 is in the first position, closing the opening 2 of the housing. On Fig.3b shows a view in section along the line a-a, presented on Figa. The interaction between the protective flap 4 and the gasket 3, attached to the body 1 of the coupling when closed protective hinged cover 4 is easy to understand on Fig.3b, especially at the top and bottom. The method, in accordance with which the protective flip cover 4 interacts with the sealing gasket 3 in the side gap under seal when closed protective hinged cover 4 can be noticed in Fig. 3C - 3E. These figures are provided in section along lines B-b, C-C and D-D shown in Figa.

Often the spine, from the view presented on fig.3b, you can see that the gasket 3, attached to the end surface of the housing 1 And is allocated to the upper sealing region and the lower sealing region 3b. These two sealing areas 3A and 3b extend mainly parallel to the axis R of rotation, around which rotates a protective hinged cover 4 relative to the body 1 of the coupling.

Protective flip cover 4 has a contact area on the edge, which in the first (closed) position protective hinged cover 4 is in contact with the corresponding sealing areas of the gasket 3 to the sealing body 1 of the coupling from the environment. Here it is essential that the contact area of the protective hinged cover 4 has been divided into separate sections, and these individual plots are used for respective sealing areas of the gasket 3 and executed properly.

In particular, of the type presented in figure 2 and 3b, it can be noted that the protective flip cover 4 is a plot of the contact area, made in the form sealing surfaces 5A, which must be paired with an upper sealing region 3A of the sealing strip 3, which is oriented mainly perpendicularly to the end surface of the housing in the closed position, the hinged protective cover 4. In other words, when the protective flip cover 4 is in the closed position, the area of the contact area, made in the form sealing surfaces 5A and mated with the upper sealing area 3A, radial contact with the upper sealing area 3A from the outside.

On the other hand hinged protective cover 4 is in contact with the lower sealing area 3b of the sealing strip 3 through the area of contact is also made in the form of a sealing surface 5b in the closed position, the electrical contact coupling 100, however, the contact is from the front. Therefore, the area of contact is mated with the lower sealing area 3b, made in the form sealing surfaces 5b, oriented predominantly parallel to the end faces And bodies.

Next, with reference, in particular, on figs-3E is a description of the design of the contact area, which is in contact with the side sealing regions 3C/3C' of the gasket 3 in the closed position, the hinged protective cover 4. The detail on Figs shows a view in section along the line B-B, presented on Figa, and Fig.3d shows a view in section along the line C-C, and five shows a view in section along the line D-D.

When comparing species in the context presented on figs-3E, one can see that the plot area is of intacta, which is in contact with the side sealing region 3C of the gasket 3 in the closed position, the hinged protective cover 4 made in the form of three-dimensional sealing surface 5C. The sealing surface 5C radially in contact with the sealing area 5C on upper side of the sealing region 3C outside, and the sealing region 5C is in contact with the sealing area 3C in the lower section of the side sealing region 3C is coming from in front. Thus the orientation of the sealing region 5C is continuously changed from the position presented on Figs, to the position represented at five. Therefore, the area of the contact area associated with the side sealing areas 3C, 3C', made in the form of a three-dimensional sealing surfaces 5C, 5C', which is: rotated 90. In particular, this can also be seen in Figure 4.

In particular, figa shows a perspective view of the housing 1 coupler approximate variant of the electrical contact coupling 100 in accordance with the invention, however, for clarity, shows only the contact area of the protective hinged cover 4.

In particular, figa you notice that a separate sealing surface protective hinged cover 4 are connected together tangentially, with the seal surface 5A, coupled with the top of the sealing her area 3A, extends primarily horizontally, and the sealing surface 5b, coupled with the lower sealing area 3b, extends predominantly vertically. Two side sealing surfaces 5C, 5C' 3C, 3C', paired with side sealing areas, rotated 90.

The special configuration of separate sealing surfaces 5A, 5b, 5C, 5C' protective hinged cover 4 provides that when rotating the hinged protective cover 4 relative to the body 1 of the coupling about the axis R of rotation, the contact area of the protective hinged cover 4 is not in contact with the gasket, while not directly be reached closed position. Thus, the lateral sealing area 3C, 3C' are not exposed to friction, until it reaches the final closed position, when the protective flip cover is rotated relative to the body 1 of the coupling. In particular, it is also evident from Fig.4b, which shows the housing 1 of the electrical contact coupling 100 shown in figures in perspective, however, for clarity, shows only the sealing surfaces 5A, 5b, 5C, 5C' protective hinged cover 4, the hinge attached to the body 1 of the coupling. In contrast to the view presented on Figa, fig.4b shown hinged protective cover 4 is rotated 10 degrees Rel is relative to the clutch housing 1 from the closed position (see Figa).

It is obvious that in the position shown in Fig.4b, the sealing surface protective hinged cover 4 and, in particular, the lateral sealing surfaces 5C, 5C' is no longer in contact: with the sealing gasket 3, and, in particular, with the side sealing areas 3C, 3C', so that the gasket 3 is no longer in contact with the protective flap 4, which is moving relative to the housing 1, therefore, is not subject to friction. In detail, the sealing surfaces 5C, 5C', paired with side sealing areas 3C, 3C', made with the possibility of absence in contact with the sealing gasket (side sealing areas 3C, 3C') to the last 5 move protective hinged cover.

Thus, it should be noted that using the solution in accordance with the invention, a protective hinged cover 4 can be firmly pressed against the sealing gasket 3 surrounding the opening 2 of the housing in order to achieve the tightness of the housing 1 clutch in rosapenna position. On the other hand, there is negligible friction on the protective hinged cover 4, when the gasket 3 is opened or closed, so that the gasket 3 is not compressed or is not used up during such movement. Only at the beginning of the opening Il is directly at the end of the closing of the contact area of the protective cover 4 is in contact with the sealing gasket 3.

Figure 6 electrical contact coupling 100 according to the embodiment is attached to the corresponding optionally performed protivoalergicescoe contact coupling 100'. Since the construction protivoalergicescoe contact coupling 100' is identical to the construction of the electrical contact coupling 100, the individual components protivoalergicescoe contact coupling 100' will not be described here in greater detail.

In particular, from Fig.6 it should be concluded that the respective sealing strips 3, 3' are pressed to each other in the coupled position of the electrical contact coupling to protect the coupling elements, respectively contacts coupled electrical contact couplings 100, 100' from moisture and/or contamination.

The invention is not limited to a variant of the electrical contact coupling, represented in the drawings, but rather is evident from the consideration of all signs.
