Description

The invention relates to a socket, in particular for an RJ-45 connector, with one through a back wall limited plug-in area and one on the other side of the The insulation displacement area located at the back, at least a contact conductor arranged in the plug-in area for Insulation displacement area is guided (WO 96/37017 A).

The RJ-45 connector is an after DIN EN 60 603 part 7 / IEC 60 603-7 standardized and worldwide applied standard for communication and data networks.

Have conventional sockets for such RJ-45 connectors a standardized mating face have insulation displacement terminals or soldering pins for connecting an external data cable or a printed circuit board and are designed for series production.

In the known sockets, the guide is the contact conductor complex, (electrical) long and in a large area the contact tracks run parallel to each other. The has a negative effect on the electrical properties of the Socket (e.g. near-end crosstalk) and increases the assembly effort in series production.

The mentioned standards for RJ-45 connectors, namely DIN EN 60 603 Part 7 / IEC 60 603-7 contains a specification for the Geometry of the opening, d. H. the mating face. On the other hand there are it for the course of the contacts from the mating area no regulations.

In Figures 1 and 2 are two construction principles of currently available and on the market Sockets shown. According to the variant of Figure 1 is a Contact conductor passed through the bottom part to the Insulation displacement area to be led out upwards. This variant is due to a relatively long electrical Connection path between the contact points in the plug area and the insulation displacement terminals. Furthermore, a Variety of tracks of contact conductors along their entire Length parallel, so that they influence each other electrically. Furthermore, in the variant according to FIG. 1 there is an increased Manufacturing effort to determine because after insertion of contacts in the socket-forming plastic part in one additional work the contacts in the plug area in their End position must be bent. Even the variant after Figure 2 has the problem of parallel routing of the contact conductors on a substantial part of their track length.

The invention has for its object to provide a socket which is a simple, fast and inexpensive series production allowed, shortest electrical connection paths the contact conductor with the shortest possible parallel routing are selected.

This task is achieved in a generic socket solved that the contact conductor is essentially perpendicular the rear wall is led through to the insulation displacement area (4) or solder pin area and there Piece runs along the rear wall (8) of the socket.

The contact conductor is preferably in a central region the height of the rear wall passed through this. Thereby there is a manufacturing advantage.

The socket is preferably made of an upper part and a lower part formed, the contact conductor between these is led. This makes the socket easy to insert mount the contact conductor.

The contact conductors are on the insulation displacement area facing side of the rear wall in the direction of the insulation displacement terminals diverging led. As a result, the contact conductors are only in the Mating area run parallel to each other. After passage the distance between the contact conductors is through the rear wall greatly expanded.

Two adjacent contact conductors are in the insulation displacement area preferably performed in opposite directions. Thereby the contact distance after passing through the rear wall enlarged to the maximum.

The insulation displacement clips are on the outside of the rear wall attached or through the contact conductors connected to them adequately held.

An (additional) plastic cap is preferred for putting on provided by cable cores to the insulation displacement terminals. Thereby the cable cores can be used without tools using the insulation displacement clamps get connected.

A pre-bent contact conductor is in the lower part usable, and the lower part snaps onto the upper part fixable. During assembly, the already finished bends are made Contact conductor inserted in the lower part and then the top is put on and preferably fastened with a snap-in connection. It is not additional bending process required to get the contacts in to bring their final position.

As can be seen in FIG. 6 and in FIG. 7, one is in the plug-in area guided contact conductor 6 through a rear wall 8 of the Socket passed vertically. After the back exit Adjacent contact conductors run from the rear wall 8 6, 6 'divergent or in opposite directions. The Bushing according to the invention is formed by an upper part 10 and a base 12 adapted thereto, the contact conductor 6 passed between the lower part 12 and the upper part 10 is. One half of the rear wall 8 is through the upper part 10, the other half through the lower part 12 educated. To simplify manufacturing, one is already pre-bent contact conductor 6 inserted in the lower part 12, an additional step of bending the contact conductor eliminated. After inserting the contact conductor 6 the top 10 is put on and by snap-in connection engaged.

After exiting the back of the rear wall 8 run the contact conductors 6, 6 'diverging to have at their end Insulation clamps 14 to be connected in mutual Distance are arranged. As can be seen in FIG a insulation displacement area 4 by four at the same height side-by-side insulation displacement terminals 14 and opposite arranged four further insulation displacement clamps formed. The Insulation clamps 14 are either connected to them Contact conductor 6 held sufficiently, or alternatively on the rear wall 8 attached.

Through the plastic part 16 shown in FIGS. 3 and 4 cable wires are attached to the Cutting clamps attached. For this purpose are in the plastic part 16 corresponding to the insulation displacement connectors 14 Cutouts formed in which the cable wires are inserted are. The socket according to the invention is regarding one very small and compact design in compliance with the mentioned standards optimized.

According to a further aspect of the invention, the contact tracks are Adjacent contact conductor in the area of the rear wall crossed to eliminate interference potential. According to another Aspect of the invention are additional shield plates between adjacent contact tracks in the area of the rear wall outside or in the rear wall to shield against interference from the mating area and the environment, or around the entire socket provided.

Instead of the insulation displacement terminals, soldering pins are alternatively provided, with the help of which the socket is soldered to a printed circuit board becomes. Applying the cable cores with a plastic cap eliminated.

The illustrated socket according to the invention offers both manufacturing perspective as well as in terms of measured electrical characteristics a conventional sockets superior design.
