PCB plug-in device

Technical area

The invention relates to a printed circuit board plug-in device for connecting connecting leads of a plug-in part to printed conductors of a printed circuit board.

State of the art

In order to connect cables of a connecting cable with conductor tracks on a printed circuit board, various direct plug-in devices are known. They often consist of a strip-shaped plug-in part, which is plugged onto a patch panel, which is formed at the edge of the circuit board and in which conductor tracks are led out by contact surfaces.

Such printed circuit board direct connectors are also used when connecting telecommunications equipment. When connecting an ISDN system, it may be necessary to connect either an external ISDN office or an internal S0 device to the so-called S0 port of the system. These two connection configurations are described in the service manual for the HiPath 3000/5000 V4.0 ISDN telecommunications system. The two connections require a change in the S0-4-wire interface, once the connection lines are connected continuously and once crossed in pairs. So far, the connecting cables have been crossed by hand, ie a housing cover has been removed from the system on site and SR and SX cores in the connection box have been manually interchanged. The manual transfer of the lines is not only time consuming, but can also lead to errors. To change a pinout of a printed circuit board connector, DIL switches or multiple plug-in devices are known.

Another possible solution is provided by specially designed contacting devices. They exist i.d.R. from a, on the edge of the printed circuit board formed plug-in field, on which a bridge spring strip is plugged. Through a connection layout on the circuit board, the desired pin assignment of the PCB connector is specified. Such a contacting device is known for example from the unpublished patent application DE 103 17 588 of the applicant.

From DE 198 199 06 A 1 an ISDN four-wire interface is known in which a switch between internal and external operation is carried out automatically by electronic switches.

Changing the pin assignment of a plug-in device is always associated in the known state of the art with a greater or lesser effort for additional components. One strives to keep the cost of additional components as low as possible.

Presentation of the invention

Object of the present invention is to provide a printed circuit board connector for connecting

To provide connecting cables of a male part with printed conductors of a printed circuit board, in which a change in the pin assignment is possible in a simple manner and with low production costs. This object is achieved in a printed circuit board connector of the type mentioned by the following features:

- The male part contains contact elements which are connected to the connecting lines, for pluggable recording of the male part is formed at one edge of the circuit board, a patch panel, the patch panel contains contact surfaces are led out through the conductor tracks on the edge, said

Conductor tracks, which are present through a contact surface and conductor tracks which are led out through at least two contact surfaces, between the plug-in part and the plug-in field, a coding guide is formed, which is a first

Plug position, and one, the first plug position offset laterally at a distance in planes of the printed circuit board at least one further plug position, wherein the contact elements in one and in the at least one further

Plug position are assigned different contact surfaces.

A significant advantage of the invention is that a change in a pin assignment can be brought about simply by a lateral plugging a male part. For the male part at least two slots are provided in the patch panel. Each slot is specified in the manner of a key-lock configuration by a mechanical coding, ie only certain plug positions are allowed on the patch panel. The coding guide is made by positive connection between male and male. A connection layout connects cables on the printed circuit board with contact areas in the patch panel so that printed conductors and connecting cables can be assigned in a predefined manner. In other words, the connection layout sets the various connectivity options Tracks and connecting cables fixed. A change in the pin assignment requires only a change, but not additional components such as DIL switches or special encoding devices. Since the effort for the connection layout and for the mechanical coding is comparatively low, thereby the realization of a possibility of changing a pin assignment is possible in a simple manner. There is no expense for additional components. The production costs are low.

Advantageous embodiments of the invention are the subject of dependent claims.

A preferred embodiment of the invention is characterized in that the coding guide by a in the

Receiving shaft of the male part formed Codiersteg which cooperates with corresponding Kodierausnehmungen in the patch panel. Each approved plug position corresponds to a pin assignment when tapping the electrical signals conducted to the contact surfaces in the patch panel.

For an ISDN connection is in a preferred

Embodiment, the circuit board connector characterized as follows: The patch panel has 6 contact surfaces. Of these, a first contact surface is a first

Conductor and a second contact surface connected to a second conductor track. A contact surface pair adjacent to the first contact surface is connected to a third conductor track and a contact surface pair adjacent to the second contact surface is connected to a fourth conductor track. On both sides adjacent to the first contact surface each have a Kodierausnehmung is formed, in which the Kodiersteg is inserted. As a result, two plug positions are coded in the patch panel, in which either a continuous or a pairwise crossed connection is made. To change the pin assignment, it is only necessary that the male part between the first and the second slot is reconnected. The SO port of an ISDN connection can thus be easily reconfigured between a connection of an ISDN exchange and a connection of an ISDN device. It eliminates a manual crossing of connecting cables. The technical realization is cost-effective. The male part is preferably made of plastic injection molding. The Kodiersteg can be easily manufactured during the injection molding of the male part. The coding recesses in the plug-in field can be easily produced by milling the printed circuit board.

A small width of the male part can be achieved in that the contact surfaces and Kodierausnehmungen are rectangular and are arranged parallel to each other in the patch panel in the plug direction.

It is preferred if the Kodiersteg connects opposite broad surfaces of the receiving shaft. As a result, the Kodiersteg also serves as a stiffening in the receiving shaft in addition to the mechanical coding. The walls of the receiving shaft can thereby be formed very thin-walled, which requires less material in the production.

To insert the plug-in part threading the

To make Kodiersteges as simple as possible in a Kodierausnehmung, it is advantageous if the Kodiersteg is guided to the opening plane of the receiving shaft. If the Kodierausnehmungen are slot-shaped, the dimensions may advantageously be selected so that the, lying in the opening plane of the male part face when inserting forms a stop surface. An electrical contact between contact elements and contact surfaces is only made when the male part is placed correctly in the selected insertion position. In a particularly preferred embodiment of the invention it is provided that the receiving shaft is wider than the patch panel. The dimensions are selected so that in an inserted position, an inner side surface of the receiving shaft rests against the facing side surface of the patch panel.

In order to connect connecting cables, which are already connected to a connector of the type RJ-45, to the plug-in part, in a variant of the invention it is provided that the plug-in part on a rear side facing away from the opening of the receiving shaft a mini-Western socket (according to DIN EN 60603-7), in which a Miniwesternstecker with connected leads is pluggable. The male part here forms an adapter, the pin assignment can be changed easily by simply repositioning between the first and the second plug position on the patch panel.

To connect leads directly to the male part is provided in another variant, that the male part is provided with screw terminals.

With regard to the contact properties and the mechanical definition of the male part on the patch panel, it is advantageous if the contact elements are designed as fork-shaped contact springs. As a result, the contact springs embrace the outer edge of the patch panel in a plugged position and hold the plug-in part by spring force.

And to further improve the contact properties and to maintain them for the longest possible service life, it may be favorable if the contact springs and / or the contact surfaces are provided with a corrosion-resistant coating, particularly preferably with a coating of gold or a gold alloy. As a material for the male part, a fire-retardant, polymeric material is preferably used. The production in large numbers can be done with advantage by plastic injection molding.

Preferably, the circuit board connector according to the invention is applied to an ISDN telecommunications system to set up the S0 port for either an external (external) digital terminal or for an (internal) ISDN terminal connection.

Convenient is when the first and the second Kodierausnehmung spaced in a pitch and adjacent to the first contact surface is arranged. This asymmetric arrangement ensures that the male part can not be pushed onto the patch panel in a position rotated by 180 degrees.

FIG. 4 shows the plug-in part plugged onto the plug-in field in a sectional drawing, wherein the connecting cable is connected by a screw-type clamp connection.

Embodiment of the invention

In the figures 1 and 2 as a whole by the reference numeral 1, an embodiment of the circuit board connector according to the invention is characterized, as used for example in an ISDN telecommunications system for configuring a pin assignment of an ISDN connection.

The spatial representations in Figure 1 and Figure 2 show a strip-shaped plug-in part 3, which is in each case in a position before plugging on the patch panel 4 of the circuit board 2. At the male part 3, a connection cable 20 is struck with connecting lines 26. The male part 3 has a cuboid receiving shaft 15, in which four contact elements 11,12,13,14 can be seen. In the receiving shaft 15, a Kodiersteg 23 is further formed, which extends between opposite broad sides of the receiving shaft 15. In the illustrated application of an ISDN connection, the four contact elements 11, 12, 13, 14 of the plug-in part (3) face six contact surfaces 5, 6, 7, 8, 9, 10 on the plug-in field 4, wherein the contact surfaces are arranged in a row next to each other.

The patch panel 4 projects tongue-shaped from an edge 24 of the circuit board 2. The contact surfaces 5,6,7,8,9,10 are rectangular in shape and connected to four interconnects 31,32,33,34 of the circuit board 2.

Further, the patch panel 4 is provided with two Kodierausnehmungen 21 and 22. This Kodierausnehmung 21 and 22 are arranged at a distance 25 and made by milling on the patch panel 4. They run on both sides to and parallel to the contact surface 9. They form a key groove for the Kodiersteg 23rd

Due to the selected asymmetrical arrangement of the Kodiersteges 23 and the Kodierausnehmungen 21,22 is excluded that the male part 3 can be plugged in a 180 degrees rotated position.

In the illustration of Figure 1, the Kodiersteg 23 is in an insertion position for insertion into the first Kodierausnehmung 21. In contrast, Figure 2 shows the laterally shifted to the left second insertion position. The Kodiersteg 23 is here opposite the second Kodierausnehmung 22. The Kodiersteg 23 has a width of 0.7 mm. The first and second Kodierausnehmung 21,22 is slightly wider than the Kodiersteg so that the male part 3 by hand can be easily attached to the patch panel 4. The two Kodierausnehmungen 21 and 22, and the

Contact surfaces 5,6,7,8,9,10 are each spaced in the grid (1.27 millimeters to 3.5 millimeters). The contact surfaces 5,6,7,8,9,10 are shown in the Embodiment led out on an upper side of the conductor; but it is also conceivable that the contact surfaces are led out at the top and / or at the bottom. The connection between the contact surfaces 5, 6, 7, 8, 9, 10 and the conductor tracks 31, 22, 33, 44 is predetermined by a connection layout 30 on the printed circuit board 2. As can be seen from FIG. 1 and FIG. 2, in the present application this connection layout 30 connects the contact surface 6 only with the conductor track 31 (ISDN signal SX2) and the contact surface 9 only with the conductor track 33 (ISDN signal SX1). In contrast, the conductor 32, which leads the ISDN signal SR2, led out in the patch panel 4 by two contact surfaces 5 and 7. Likewise, the conductor 34, which leads the ISDN signal SRI, led out twice in the patch panel 4, namely by the connection with the contact surface 8 and by the connection with the contact surface 10. In other words, contact surfaces are present in the patch panel, which only with a conductor track are connected (contact surfaces 6 and 9) and on the other hand there are conductor tracks 32 and 34, which in

Patch panel 4 each in two contact surfaces 5 and 7 or 8 and 10 open. As a result of this assignment, the ISDN signals SXL and SX2 in the patch panel 4 each at a contact surface, the ISDN signals SRI and SR2, however, are each tapped at two contact surfaces.

In the present application, this means that when on the S0 board of a communication system, either an external ISDN office or an internal SO device to be connected, so the required pairwise crossing of connection lines can be achieved simply by the male part 3 with the Kodiersteg 23 either in the first Kodierausnehmung 21 or laterally offset in the second Kodierausnehmung 22 is inserted. The arrow 29 indicates in Figure 1 and Figure 2, the plugging direction. The result is the following assignment between contact elements and ISDN signals:

In the first plug-in position of the Kodiersteg 23 in the first Kodierausnehmung 21 is inserted (Figure 1).

In the second plug-in position of the Kodiersteg 23 is inserted in the second Kodierausnehmung 22 (Figure 2).

As can be seen from the comparison of the two tables, the ISDN signals picked up by the contact elements 11, 12, 13, 14 of the plug-in part 3 are crossed in pairs in the respective plug-in positions, which equates to manual swapping of connection wires.

Since the male part 3 can only be plugged into this first or second plug position on the patch panel 4, are errors when configuring the ISDN connection, as it can occur during manual swapping of the connecting wires, excluded.

As drawn in FIG. 1 and in FIG. 2, the cuboid receiving shaft 15 of the plug-in part 3 has side walls 16 and 17. The width of the receiving shaft 15 is wider than the width of the patch panel 4. The Kodiersteg 23 divides the receiving shaft 15 asymmetrically in a, seen in the direction of view larger left and a smaller right compartment. In the left part of the shaft are the

Contact elements 11,12 and 13. Between the contact elements 12 and 13, a grid space is free; Also, the outer surface lying to the inner surface 16 and 17 is left free in each compartment. The contact elements 11,12 and 13,14 and the contact surfaces 5,6,7,8,9,10 and Kodierausnehmungen 21,22 are each spaced at a distance 25 (pitch) arranged side by side.

In the first insertion position shown in Figure 1, the inner side surface 16 is aligned with the corresponding side surface 18 of the patch panel 4. The dimensions are selected so that during the insertion process (arrow 29), the surfaces 16 rests on the surface 18. In this way, an additional guide when inserting. The same applies to the second insertion position shown in Figure 2. When plugged into this slot is the, seen in the viewing direction right side surface 17 of the male part 3 on the side surface 19 of the patch panel 4. Again, the system of surfaces 17 and 19 forms an additional guide.

The Kodiersteg 23 has an end face 36 which terminates flush with the opening plane of the receiving shaft 15. The elongated depth of the Kodierausnehmung 21 and 22 is so dimensioned that the end face 36 acts as a stop at Einsteckecken.

The connection lines 26 of the cable 2 can be either pluggable or permanently connected to the male part 3. The sectional drawing in Figure 3 shows in a first variant, the connection of the connecting cable 20 through an RJ-45 connector 27. In Figure 4, the connection is made by a screw 28 in a second variant. The connector 27 and the screw 28 are each formed on a receiving shaft 15 facing away from the side of the male part 3. As can be seen from the sectional view, the contact elements are fork-shaped.

Of course, the mechanical coding 23, 21, 22 can also be realized by a different design of the mating field between the plug-in field 4 and the receiving shaft 15. For example, the Kodierausnehmungen be formed by formed in the patch panel 4 and extending in the insertion direction 29 grooves. In these grooves then engages - instead of Kodiersteges 23 - in the receiving shaft in the direction of the patch panel projecting coding or a similarly congruent trained coding approach.
