The technical FIELD

The present invention relates to a connector attached to the connection panel on the trains couplers, and a connector configured to connect the communication networks that are installed in rail vehicles intended for connection of the couplers of the train.

BACKGROUND AND PRIOR art

In order to meet the demand of passengers in communication via the Internet while traveling, in rail vehicles can be installed broadband for high-speed data transmission. Preferably, the network, which is separately installed in rail vehicles made with the possibility of Association to share hardware and software required for network management data. Intended for this connector must meet certain requirements.

First of all, the connector must provide the data in accordance at least with the IEEE 802.3u Ethernet determining a data rate of 100 Mbit per second.

High speed data transfer requires the transmission of signals at a frequency of 100 MHz, and thus, the connector needs the electromagnetic shielding that is to run interference from other electromagnetic sources, such as adjacent connectors.

The connector must also withstand exposure to the environment, including humidity, dust, extreme temperatures, and dynamic loads and vibration generated during operations on the clutch and during the movement of the train.

Preferably, the dedicated connector must be performed with automatic connection/disconnection of the communication networks for coupling/decoupling rail vehicles.

The INVENTION

The purpose of the present invention to provide a connector in the connection panel on the couplers, train, and these connector and connecting the panel should be capable of transmitting signals at a frequency of 100 MHz between rail vehicles connected together in a train.

Another objective of the present invention is to create a connector in the connection panel on the trains couplers, and connectors are made with the possibility of easy and individual replacement.

Another objective of the present invention is to create a connector in the connection panel on the automatic coupling of the train for the transmission of signals at a frequency of 100 MHz and executed with automatic connection/disconnection when the coupling/decoupling rail tra the transport means in the train.

One or more of these purposes are achieved by a connector and a connecting panel, made in accordance with the attached claims.

Briefly, the present invention provides a connector through which data signals are transmitted between data networks, separately installed in the connected rail vehicles. The connector includes a holder of a contact made to lock in the connection panel coupler trains, and a metal shell contact, which can be inserted into the front end of the holder contact, and the metal contact element is fixed in the casing of the contact and made so that it passes electrically isolated through the casing to contact the terminal of the conductor, which is located at the rear end of the holder contact.

In accordance with this decision, the following is achieved:

electromagnetic shielded connectors due to the high frequencies can be set in any desired position in the connection panel, without the need for modification. In other words, one and the same holder contact, if desired, can be used to install shielded connectors made for the connection of conductors of the data with a speed of 100 Mbit/CE is, or to install a monolithic connector intended for connection of the power conductors.

The casing of the contact and the contact element is made together with the possibility of removal from holder contact, while the latter remains fixed in the connection panel. Worn or damaged connector can thus be individually replaced on the front connection panel without removing the holder into contact with the connection panel. The solution has advantages both from the point of view of reducing the maintenance time, and from the point of view of the improved economy.

Preferably, the casing of the contact protrudes forward from the contact element for engagement with a corresponding connector prior to engagement of the contact element in the connection. A contact element secured thereby from damage and provided with a driven connection with a corresponding contact element.

In one preferred embodiment, the contact element contains the diameter of the metal casing and protruding from the housing, the rod of smaller diameter. The housing is fixed in the Central axial channel passing through the housing, and the rod is held in the axial direction beyond the rear end of the casing contact. The housing and the rod may be you who Olney as a whole and is made by treating a suitable metallic material or material of a metal alloy on a lathe. One suitable material is stainless steel, other, for example, copper.

The design of this variant execution ensures reliable operation despite the small size, in which the diameter of the contact element is in the range from about 1 mm or even less in the core section of approximately 3 mm in the section of the body.

The holder of the contact has a front pocket that is designed to fix the rear end of the casing, and the rear socket, made at some distance from the front slot. The rear socket is designed for fixation of the cable conductor, and the passage from the front jacks to the rear of the socket is designed for passage of the rod of the contact element in the rear socket.

This run provides unlimited flexibility in assignment of the connectors for high frequency data transmission and for power transmission at a low frequency.

The contact element is inserted into the Central channel through the casing of the contact and from the front end of the casing contact. The contact element is fixed in the axial direction between the front and rear radial shoulder, made in the channel through the casing contact, and between the flange and the housing contact element inserted spacer elements made of a dielectric material.

One of the separating elements made of elastic material is flexible in the radial direction. During insertion into the channel when the radial compression of the flexible separating element can extend in the radial direction behind the front shoulder, clipping, thus, the housing contact element behind the front shoulder.

This option execution provides a simple installation by inserting the contact element held therein dividing elements, from the front end of the casing contact until such time as the flexible separating element snaps into place behind the front shoulder.

Preferably, the separator elements coaxially held on the contact element and carry out the centering of the contact element concentric with casing contact. Thus, the separator elements provide the formation of the annular gap between the housing contact element and the surrounding wall of the channel through the casing contact, and through this gap contact element is electrically separated from the casing of the contact.

In the connector, in which the casing of the contact has the form of a socket contact, the contact element includes a contact pin extending from the front end of the housing contact element.

In the connector, in which the casing of the contact has the form of a pin contact, the contact element includes a contact sleeve, made in the front end of the housing of the contact element.

In this implementation, as described above, the available dimension of the connector is used in an optimal way.

Similarly, the present invention provides a backplane in a couple of trains, in which in the front part of a series of connectors designed to mate with corresponding connectors of the connecting panel for electrical connection of rail vehicles, which are connected together by couplers trains. At least some of the connectors in the connection panel are effective to transmit signals at a frequency of 100 MHz through electromagnetic shielded contacts, performed as described above.

Similarly, the proposed couplers, and the data transmission network rail vehicle that enables you to achieve data transmission at 100 Mbit/sec. through a backplane and connectors, as described above.

BRIEF DESCRIPTION of DRAWINGS

In more detail, the invention is described below with reference to the attached drawings. In the drawings:

Figure 1 depicts the trains couplers containing a backplane, front side which faces forward to mate with a corresponding connection pad on the left side of the couplers when the join operation;

Figure 2 depicts a section through the connecting panel, while the p schematically;

Figa and 3b depict a longitudinal section through a pair of connectors connected together in accordance with the present invention.

A DETAILED DESCRIPTION of the PREFERRED OPTION RUN

Figure 1 shows the couplers 1 train containing the drawbar 2 and head 3. In operation, the traction rod 2 coupler attached to the chassis rail of the vehicle, which is not shown in the drawing, and the head of the coupler is configured to interlock with a corresponding cylinder, a counter-coupler trains.

The connecting plate 4 is supported on the head of the coupler and the connecting panel contains a number of connectors 5, facing forward on the front side of the panel 4. Although it is not shown in the drawing, it is understood that the group of conductors extends from the rail vehicle to the rear connection panel. The location of the connection panel and connectors provides automatic connection with mating connectors to a corresponding connection pad when the clutch counter, suitably equipped with automatic coupling. Thus, in the United state of the patch panel and connectors transmit power and signals between interconnected rail vehicles.

With denitely 5, supported in the connecting panel 4, in the General case can be interpreted as containing a contact in the form of a socket and a contact in the form of a pin made with the possibility of a coaxial connection. Thus, the connectors 5 are usually symmetrical shape rotation and have a few aspects of the overall design; for this reason, further description is suitable for female connectors type and connector pin type, unless otherwise indicated.

The connectors 5 are used to transmit power and/or signals to control the operation between the United together rail vehicles. To perform an increasing number of functions in rail vehicles, the connector 5 is made so that the connecting panel could be placed a large number of them. The connectors are usually placed parallel to the horizontal and vertical rows, as shown in the drawing, leaving limited space between adjacent connectors.

The connectors 5 are installed individually in panel 4 by means of the contact holder 6, as can be seen in the context of figure 2. In the connection panel 4, the holder 6 of the fixed contact in the housing 7, which is made of a dielectric material and secured in the connection panel. More specifically, the holder 6 su is Allen in the slot 8, which is made in the casing 7. In the depicted embodiment, the holder 6 made contact with it clicks into the slot. For this purpose, the holder of the contact has a front end, made in the form of a sleeve 9 made with the possibility of compression in the radial direction due to the axial grooves 10, made in the front end of the holder contact. Acting in the radial direction of the flange 11 is closed by the front end. When the radial compression of the front end of the holder pin can be inserted into the slot 8 from the rear side of the connecting panel. Once inserted, the front end with grooves returns to its unstressed shape, while the flange 11 engages over the edge, which limits the forward end of the slot 8.

The holder 6 includes a first front slot 12 that is designed for inserting the rear end of the connector 5. The connection between the holder of the contact and the connector is made detachable, including, by way of example, a threaded connection. In the mounted position, the front part of the holder 6 of the contact in the form of a sleeve supported from the inside by the emphasis in the outer part of the connector, and to this end, the connector can be made with a protruding in the radial direction of the flange 13. The flange 13 may have a slightly conical shape, to cause expansion in the radial direction of the front is the end with the slots, providing, thus, a strong connection holder contact and connection panel.

The second rear slot 14 is separated from the first/front slot 12 in the opposite end of the holder 6. This is the second/rear socket 14 is intended for inserting an electrical conductor into the holder 6 through which electricity is transmitted to the connector 5.

While I explored the connection panel containing connectors made effective for the transmission of power and/or signals that control the functions of a rail vehicle, usually described by a harmonic signal of the form, oscillating at a frequency of 50 Hz. Data transmission in a broadband range of 100 Mbit/sec, according to the Ethernet Protocol requires transmission of square wave oscillating at a frequency of 100,000 Hz, or 100 MHz. Under such conditions, the connector 5 will work as an antenna, through which an external electromagnetic field and the activity will interfere and increase the noise relative to the signal that should be protected around the metal screen in the connections pane.

The connector 5' - modified compounds of data networks in the broadband range in rail vehicles depicted on Figa and 3b, illustrating a pair of mated connectors in the longitudinal section. the each connector 5' contains metal casing 20 contact intended for insertion in the front end of the holder 6, and a metal contact element 21 fixed in the casing of the contact and the element 21 protrudes through the casing of the contact to the terminal 22 of the conductor located in the rear end of the holder 6. The casing 20 contact is made with the possibility of withdrawing in front of the socket 12 and the terminal conductor placed back in the socket 14 of the holder contact, as explained above.

The contact element 21 is supported in the Central channel 23 through the casing 20 of the contact and inserted from the front end of the casing 20 of the contact. The contact element includes a housing 24 having a first diameter, and the rod 25, having a second diameter, smaller than the first diameter, and the stem protrudes from the housing in the rear direction. The housing 24 is fixed within the channel in both axial directions. To this end, the channel 23 has a front and rear flange 26 and 27 made in the radial direction in the channel. Between the radial shoulder and the opposite end surfaces of the housing 24 is inserted spacer elements 28, 29, made of a dielectric material, for example polymeric material. At least one dividing element 28 made of elastic material and is flexible in the radial direction, and, thereby, made with the possibility of insertion in the channel under radial compression. When su is the t by radial compression of the flexible separating element can extend in the radial direction behind the front shoulder, clipping, thus, the housing 24 in the axial direction behind the front flange 26.

In the illustrated embodiment, the spacer elements 28, 29 are supported coaxially on the contact element 21 and provide centering of the contact element in the channel through the casing contact. Separation elements, thus ensure the formation of the annular gap 30, which provides electrical isolation of the contact element within the enclosure of the contact.

The rod 25 projects from the housing 24 through the casing 20 of the contact so that the rear end 31 of the stem protrudes from the rear end of the casing contact. Tube 32 made of a dielectric material, is concentric with the rod, providing isolation of the core from the metal casing 20 of the contact. The rear end 31 of the rod is back in the socket 14 of the holder contact through the passage 33 to engage with the terminal 22 of the conductor, which is located in the rear pocket 14. The terminal 22 of the conductor can be designed as a slot, as illustrated, is firmly fixed in the rear slot means located between the sleeve 34 made of a dielectric material. The conductor 35 in this case represents a typical single conductor included in chetyrehkamernoe Ethernet network, although this connector can also be is used in other applications.

In the left part Figa shows the connector 5'containing the casing 20 of the socket contact form. Contact element 21 here contains a pin 36 extending from the front end of the housing 24 of the contact element to a slightly distant inside the holes of the socket casing contact. In the right part Fig.3b shows the connector 5'containing the casing 20 of the contact pin shape. Contact element 21 here contains the contact sleeve 37 made in the end of the housing 24 of the contact element in a slightly distant inside end of the pin casing contact. When connecting the speakers contact housings 20 are brought into contact with the mating connector before the corresponding contact elements 21, directing them during the connection process, as well as protection in the disconnected state.

In order to guarantee electrical contact in the connection process, the contact sleeve 37 can be inserted flexible contact elements or tubular sleeve, as shown by the position number 38 on Figa and 3b. For this purpose, the contacting surface can be metallized in the usual way.

Through the application of the connector 5' in the connection panel, supported on the trains couplers, couplers, train and backplane are provided with sufficient bandwidth for broadband Yes the data between interconnected rail vehicles. Providing 100 Mbit data interface between rail transport means in practice is also a prerequisite for the installation of broadband bandwidth in rail vehicles, that is implemented by an electromagnetic shielded connector 5', made in accordance with the present invention.
