The present invention relates to an electrical connecting element for connecting a conductor to a circuit Board, or on the conductive paths, comprising a housing, at least one clamping connector for conductor and at least two connecting output preferably suitable for solder connection to circuit Board or conductive tracks, according to the restrictive part of paragraph 1 of the claims, as well as to a device that includes a circuit Board with a top side and bottom side and mounted on the upper side of circuit Board electrical connecting element for connection of the conductor, and the electrical connection element has housing, at least one clamping connector for conductor and at least two connecting output preferably suitable for solder connection to circuit boards, and circuit Board provided with positioning holes for positioning the connecting pins, according to the restrictive part of paragraph 10 of the claims.

Electrical connectors are used in various forms of execution, to connect the conductor often in the form of a cable to a circuit Board (referred to as printed circuit boards - PCB) or is the output on it conductive paths.

Such electrical connectors mounted on the conductive Board by means of protruding contact elements, hereinafter called the connecting pins, which in the installation position electrically connected with provided on the circuit Board, the respective conductive paths. Connecting the findings also referred to as mounting pins (pins for soldering), because they usually interact with existing circuit Board positioning holes and then soldered to the circuit Board. Connective conclusions there are a huge number of embodiments and are usually circular or rectangular cross-section.

Based on the high-density layout of the components provided on the circuit Board, it is desirable if possible miniature electrical connecting elements.

However, the decrease in the electric connecting elements meets a certain limit due to required safe interval between the individual connecting pins.

Such safe spaces most often prescribed by regulations, in order reliably to prevent breakdown and, thus, a short circuit between adjacent connecting pins, and vary according to the height of tension, p is iLounge to an electrical connecting element or the connecting output.

A specific voltage, which is necessary to prevent the flow of current through the insulator, according to the standard configurations of circuit boards, in particular through the air trapped between adjacent connecting pins, essentially proportional to the path length, hereinafter referred to as "plot (path) voltage, which must pass electrons through the insulator or through the air to reach from one connecting the output to the other of the connecting pin and cause a short circuit. In accordance with that specified for specific material strength at break of the units In/mm While the plastic is showing strength at break, which is about 10 to 40 times the strength of air.

Mentioned safe period corresponds to when the conventional electrical connecting elements of the plot of voltage, which, in essence, should be equal to the interval between two connection pins. More precisely, a safe gap or path voltage is usually measured as the direct distance between the outer shells of the two connecting pins for the mental connection line normal to passing for the most part in the insertion direction of the electrical connecting element axes of the connecting pins, and measured so safe ex is referred to as the "air gap (spark gap).

Parallel to this is also defined another safe gap with respect to the "path of the moving discharge, which must be current along the surface of the circuit Board is to walk from one connecting conclusion to the next. The above is a safe gap type the path of the moving discharge" is often significantly higher than the safe gap type "air gap", as the surface of the circuit Board during operation can be contaminated on the surface of the circuit Board contamination, as appropriate, together with the presence of high humidity and condensation of air humidity on the circuit Board, makes easier a short circuit between the two connection pins.

Defined standards for safe intervals depend, among a class of conductor of electrical connecting elements, even from other factors, such as the use of electrical connecting elements, for example, whether they are used in industrial or home networks.

If the circuit Board in the area provided for positioning the connecting findings of the positioning holes has a metal frame, then the effective period of the voltage or "the path of the moving discharge", which the current must pass between two connective conclusions is, can further be reduced. Also, consider the thickness of the layer of brazing material, whereby the connecting conclusions soldered to circuit Board.

The basis of the claimed invention is the task of a separate connecting the findings to isolate from each other to prevent the breakdown voltage between them. In particular, it should be possible connective conclusions electrical connecting element positioned closer to each other and, thereby, to enable the use of smaller components electrical connecting element than is the case in conventional connecting elements or determined by setting described safe intervals. Despite the smaller the distance between the connecting pins should, however, be guaranteed sufficient guarantees against the risk of breakdown voltage between adjacent connecting pins.

Typical electrical connecting element for connection of the conductor with circuit boards or placed on it the Provo is asimi tracks includes a housing, at least one clamping connector for conductor and at least two connecting output preferably suitable for solder connection to circuit boards. In accordance with the invention, the housing contains on its lower side facing in the mounting position of the circuit Board, at least one speaker dividing element of an insulating material, which is, at least in areas between the connecting pins and the mounting position passes through the circuit Board.

In this way the adjacent connective conclusions insulating follows escaped from each other or increases the breakdown strength of the zone between two adjacent connecting pins, which, under traditional electrical connecting elements still was formed only air.

Thus, the path length of the voltage between the connecting pins are no longer determined in accordance with invention of the electric connecting element in the above manner as the linear distance along the normal between the two connecting pins and corresponds now to the hypothetical path, which must pass the current applied to the connecting pin, to overcome or rounding the surface of the separation element, in order to reach the neighboring connecting the output is A.

The invention is further illustrated by the examples of execution. While the drawings shows the following:

Fig - schematic representation provided with the positioning holes of the circuit Board area on the form in the plan.

Figure 1 shows the invention of the electric connecting element 1, which is manually or electronically placed in the insertion direction 14 on the circuit chamber 10 (see also figure 2).

On asunny figure 3-5 more electric connecting element 1 has a preferred way plastic case 2, which on the front side 2C is equipped with multiple locking connectors 5, and through such bridges walls 5b, respectively, made of the positioning element 5A. In positioning the element 5A of the clamping connector 5 may be appropriate conductor 6 in the direction 15 of the input and recorded by means accommodated in the housing 2 of the drive element 7 (see the representation in section 6).

In the case of drive elements 7 it can be, for example, a screw or adjusting elements, which are known manner causes the pressure introduced into the clamping connector 5 conductor 6 are accommodated in the housing 2 clamping the ferrule 9.

According to figure 3-5 case 2 is turned on from the circuit Board 10 in the mounting position of the upper side 2b integrally formed, for the most part tubular molded elements 8, which, respectively, form a hole 8A, which may be a tool such as a screwdriver to trigger located inside the housing 2 of the drive element 7, the issuing or fixing Explorer 6.

From rotated to the circuit Board 10 in the mounting position of the bottom side 2A of the housing 2 is any number of connecting findings 3 in the direction of the 14 input perpendicular to the bottom side 2A which are provided to connect to is not on asanam conductive paths of the circuit Board 10.

In the case of connecting conclusions 3 we are talking about the speakers in the form of rods electrical contacts that are fixed in the corresponding positioning holes 11 or holes of the circuit Board 10 and then soldered to it (see Fig).

Connective conclusions 3 can be performed in various ways and may, for example, be circular, rectangular or square cross-section. Typically the connective conclusions 3 are made by stamping a flat material.

Located on top of each other, clamping the connectors 5 and connective conclusions 3, respectively, are connected to each other in a conductive manner. The connecting pin 3 is connected, for example, the clamping sleeve 9 of the clamping connector 5, passes through the bottom side 2A of the housing 2 and projects from the bottom side 2A length 21 (6).

Soldering the connecting findings 3 through the soldering material 20 is typically turned on the inserted electrical connecting element 1, also called "side soldering" the bottom side 10b of the circuit Board 10, after the electrical connecting member 1 was positioned on the labeled side of the mounting upper side 10A of the circuit Board 10, and the connecting findings 3 in the region of the positioning holes 11 are output through the circuit Board 10 (see Fig.7)that this takes place is to be in electrically conductive contact with the respective provided on the circuit Board 10 by conductive paths.

Instead of mounting by soldering the electrical connecting member 1 is also another way to gain a foothold on the circuit Board 10, for example, by insertion with accurate gate.

In accordance with the invention, the housing 2 of the electrical connecting element 1 at its rotated to the circuit Board 10 to the underside 10A provided with a protruding spacer elements 4 of an insulating material, which is placed at least between the connecting pins 3 and in assembled position are specially provided for this additional positioning hole 12 of the circuit Board 10 or speak through them.

The separating elements 4 continues in this example, run essentially parallel to the connecting conclusions 3 or perpendicular to the bottom 2A of the housing 2 and, thus, perpendicular to the upper side 10A or the bottom side 10b of the circuit Board 10, and a separating element 4 is placed preferably in the middle between two adjacent connecting pins 3.

This way is shown in figure 3 way 16 voltage, which is the path that must pass electrons in the case of a short circuit to one of the connecting pin 3 to reach the next position of the connecting pin 3, is considerably increased. While the ut 16 voltage in the conventional electrical connecting element 1 corresponds, essentially, the axial distance 19 between two adjacent connecting pins 3, more precisely indicated in Fig.7. the length 13 of the gap between the outer shells of the connecting findings 3, the path 16 voltage in the case of a security which meets the invention the separating element 4 is composed of sections 16A, 16b and 16C or 16d, 16e and 16f path (also shown in Fig.7), which together provide, respectively, a longer path than the one that would require current to overcome short axial distance 19 or the length 13 of the gap.

To create a short circuit the flow of current can pass "air gap", which essentially corresponds to the sum of the legs 16A, 16b and 16C path, or the path of the moving discharge", which essentially corresponds to the sum of sections 16d, 16e, 16f, e and 16d path and passes through the bottom side 10b of the circuit Board 10 and the surface of the separation element 4. As can be seen in Fig.7, while for the calculation of passing through the bottom side 10b of the circuit Board 10 section 16d "the path of the moving discharge" should be used not just parallel to the axial distance of 19 the distance between the connecting pin 3 and the separating element 4, so that should be taken into account width printed on the circuit Board 10 of electrically conductive material 20 soldering, or it must be subtracted from the aseania between the connecting pin 3 and the separating element 4.

As the sum of the sections 16A, 16b and 16C way, i.e. the "air gap", and the sum of the sections 16d, 16e, 16f, e and 16d path, i.e. the path of the moving discharge" must be sufficiently large, that is, at least, to be of such magnitude, as already mentioned above correspond to the norms of safe spaces "air gap" and "the path of the moving discharge". Thus, it is essential that shown in Fig.7 length 22, 22', as also shown in Fig.6 width 23 of the separating element 4 are selected so that this requirement is fulfilled, and the "air gap" and "the path of the moving discharge" now is not as, respectively, a single linear path, and, as a result formed a dividing element 4 "obstacles"as intermittent path, made up of many sections of track. It is clear that the "air gap" and "the path of the moving discharge" when other geometric performing the separating element 4, as shown in Fig.7, in an appropriate case, it may be formed from other or from a larger number of stations than shown in this example implementation.

Specifically, the software corresponding to the invention the separating element 4 means that, for example, in the event of an electrical connecting element 1 provided with a nominal voltage of connection 600 V, with testwuide standards safe period "ways of moving the discharge or the length 13 of the gap between the two connecting pins 3 are installed according to the US standard as 12.7 mm, this length 13 clearance with full protection against short circuit can now be reduced to 6 mm Corresponding to the invention of the electric connecting elements 1, which are provided for the rated voltage of 600 V, we have, for example, the axial distance of 19 connecting to conclusions just 3 6.35 mm, and the diameter of the connecting output is 1 mm.

However, you should also pay attention to the fact that the path 16g voltage between the clamping connectors 5 or clamping rings 9 is sufficiently high, this wall 5b, which form a positioning element 5A, continue far enough from the conductive elements of the clamping holder 9. Similarly, the molded elements 8 should be sufficient depth, or the other way 16h voltage must be of sufficient magnitude to prevent the breakdown voltage between adjacent drive elements 7, more precisely, between the heads 17 of the drive elements 7 which are placed in the holes molded elements 8.

To prevent the breakdown voltage through the separating element 4, as well as to prevent interruption of the separating elements 4 during Assembly or during operation of the electrical connecting element 1, for example, because of concussions, the separating element 4 must have a certain minimum thickness is tenki. So the wall thickness of the separating element 4, which according to Fig.7 corresponds to the length of section 16d or 16f is in the proposed example running approximately 0,95 mm

Corresponding to the invention the separating element 4 is made essentially rectangular, but according to 6 may in its corner areas also have a chamfer 4b or fillets to ensure the best possibility to insert the separating elements 4 into the corresponding positioning holes 11 of the circuit Board 10. Connecting conclusions 3 is preferably provided with a conical end zone 3A, to allow better connection to circuit Board 10.

Instead of the shown rectangular-shaped separating element 4 can, of course, be performed in a different form, for example, shield-shaped or convex/concave or in the form of a polygon.

If the connective conclusions 3 protrude from the bottom side 2A of the housing 2 or on a line corresponding axial distance 19 between the two connecting pins 3 are not perpendicular, but from a different angle, the geometry of the separating element 4, of course, is also consistent with this process of connecting findings 3. However, in each case, it is essential that two adjacent connecting output 3 possible effectively separated from each other by RA the separating element 4, during this period of 16 voltage between the connecting pins 3 through the use of the entire available surface rectangular in this example, perform the separating element 4 increases.

Instead of placing relevant to the invention the separating element 4 on the housing 2 of the electrical connecting element 1 may each be provided on the bottom side 10b of the circuit Board 10, and a separating element 4 is either associated with the circuit Board 10, or as a separate component can be placed on the bottom side 10b of the circuit Board 10.

In the case of this alternative implementation is only necessary to ensure that the bottom side 2A of the housing 2 and the upper side 10A of the circuit Board 10 is tightly contacted with each other, i.e. without air inclusions, so that in this zone to prevent the danger of a breakdown voltage between the connecting pins 3. With this purpose, during the installation of electrical connecting element 1 is also possible on the circuit Board 10 to provide a layer of material between the bottom side 2A of the housing and the top side 10A of the circuit Board 10, which has sufficient resistivity and this zone is securely fills any voids, thus, a suitable layer of plastic or glue.

Regardless of whether the briteney dividing element 4 on the electrical connecting element 1 or the circuit Board 10, speaker dividing element 4 in this example, execution continues measured from the bottom side 10b of the circuit Board 10, perpendicular to the last length 22', which is more, preferably two times longer than the protruding above the lower edge 10b of the circuit Board 10 length 21', respectively, adjacent to the separation of the connecting element 4 conclusions 3. If the separating element 4 is technologically related to the housing 2 of the electrical connecting element 1 or formed on it, is shown in Fig.7. measured from the bottom side 2A of the housing 2, continuing in the mounting position in the direction of the circuit Board 10, the length of the separating element 4 is greater than the length 21 adjacent to the separating element 4 connection output 3.

In the proposed example of executing the connecting pin 3 is, for example, a length of 21', equal to 1.9 mm above the bottom side 10b of the circuit Board 10, and measured from the bottom side 10b of the circuit Board 10 length 22' separating element 4 is 5.6 mm Length 22' separating element 4 exceeds, thus, the length 21' of the connecting pin 3 to 3.7 mm, thus, three times more than the last. From these geometrical relations, it follows that the sum of the legs 16a, 16b and 16c way, i.e. the "air gap" is 9.7 mm, while the amount uchastka the 16d, 16e, 16f, 16e and 16d path, i.e. the path of the moving discharge" is 16 mm. Thus, the connecting conclusions 3 can accommodate a compact way, with the axial distance of 19 equal to 6.35 in relation to one another, without the danger of a short circuit.

The separating element 4 in this example run is placed exactly in the middle between two adjacent connecting pins 3, and the side view figure 6 clearly shows that passing normal to the longitudinal axis 18 of the connecting conclusions 3 or normal to shown in Fig.7. the length 13 of the gap width 23 of the separating element 4 is selected in such a way that there will be sufficient shielding action of the separating element 4. Connecting the output 3 is preferably placed in the middle of the width 23 of the separating element 4, when seen in the side view according to 6)or the separation element 4 relative to the length of its width 23 passing, essentially in the direction normal to the length 13 of the gap, located essentially symmetrically with respect to the connecting pin 3.

In the example of execution according to Fig.7, in addition, it is seen that the lower edge 2A of the housing 2 is not attached directly to the upper side 10A of the circuit Board 10, and a few distant from the upper side 10A sh the me Board 10 via formed on the bottom side 2A of the housing 2 plots 2d jumpers or through the protruding sections 4A of the separating elements 4, diameter greater than the diameter of the positioning holes 11.

Depending on the specific configuration placed on the circuit Board 10 components corresponding to the invention of the idea of providing the separating elements 4 between the connecting pins 3 can vary, so that the connecting conclusions 3 can be shielded from other sites, other than those shown in figure 1-7.

For example, in the case where multiple electrical connecting elements 1, 1' are placed with a fit to each other on the circuit Board 10, may be provided by one or more separating elements 4', which is separated by connective conclusions 3 the first electrical connecting element 1 and the connecting conclusions 3' adjacent the second electrical connecting element 1' (not shown, but see schematic representation of additional positioning holes 12'are provided for the positioning of an additional separating element 4'according to Fig 1).

In this case, several adjacent electrical connecting elements 1, 1', at least one additional separating element 4' can be placed in any other position than that depicted in figure 1 by means of additional positioning holes 12'. Augment the capacity of the separation element 4' is preferably placed anywhere on the outer region of the bottom side 2A of the housing 2 and may, for example, also be accommodated in the area of the housing 2 adjacent to the clamping connectors 5.

Shielding or isolating the effect according to the invention the separating element 4 may also be increased due to the fact that the separating element 4 is made in a shaft shape, and thus, any number of connecting findings 3, when considering the form of the plan normal to the bottom side 10b of the circuit Board 10, surrounded by a dividing element 4, or with a larger or smaller gap covered (also not shown). In other words, the separating element 4 in this case has a Jack shaft shape, inside which is placed the connecting pin 3, separated from adjacent connective output 3. The circumference of the connecting pin 3 can either sites (with any distancing from the dividing element 4), or, in the case of manufacturing a separating element 4 together with the circuit Board 10, even completely fringed by a dividing element 4. In this respect, the separating element 4 and an additional separating element 4' can also, at least in areas cross each other and constructed in conjunction with each other.

Corresponding to the invention the separating element 4 is preferably made of plastic, as with the last 30-130 kV/mm shows high isolated is that the relevant action or strength at break. However, it is also possible to produce the separator element 4 from other insulating materials, for example, from materials containing ceramic or glass.

It is clear that a typical system may have additional speakers to be inserted elements and positioning holes, which are placed either on the electrical connecting element 1 or on the circuit Board 10, which, however, only needs to prevent incorrect positioning of the electrical connecting element 1 on the circuit Board 10 and should not be confused by their functionality with the relevant invention the separating elements 4.

To ensure that between the not shown in the drawings, the conductive tracks of the circuit Board 10, leading from the positioning holes 11 for connecting findings 3, was not the breakdown voltage due to the closer placement of the connecting findings 3, is reduced relative to the same standards of safe gap can be provided that these leading from the positioning holes 11 or from the connection of findings 3 conducting paths are either in the insulating layer of the multilayer circuit Board and, thus, isolated from one another, or that the circuit Board 10, at least in areas covered by an additional insulating layer.
