BRIEF SUMMARY
BACKGROUND OF THE INVENTION



FIELD OF THE INVENTION

The present invention relates to a method for making contact between a multi-pole socket connector for plug-in connections and connecting wires.
When assembling known socket connectors, special contacting tools are used from a side position to guide and make contact with the connecting wires in the case of two-row juxtaposed socket connector elements. Thereafter, the individual fitted socket connector elements are separated from one another and assembled (snapped together, pressed together etc.) to form a multi-row socket connector. This procedure is complicated and leads, moreover, to tensile loading of the connecting wires. Consequently, crimp arrangements for relieving the insulation piercing connecting devices must be provided by means of separate crimping tools.
U.S. Pat. No. 5,368,505 discloses, for example, a multi-pole socket connector which is built up in modular fashion from a plurality of plastic plates arranged in parallel. In this case, each plastic plate holds a row of contacts with the insulation piercing connecting devices integrally formed thereon. However, before the individual plastic plates are joined, the insulation piercing connecting devices of each plastic plate are connected by means of a special tool to the connecting wires assigned to them.


SUMMARY OF THE INVENTION

It is the object of the present invention to specify a method for making contact between a multi-pole socket connector for plug-in connections and connecting wires, which can be carried out more easily and which is not so complicated as the known method.
According to the invention, this object is achieved for a method of the above type by virtue of the fact that the socket connector is assembled from a plurality of internal, and a pair of external plastic plates, the internal plastic plates being constructed in such a way that one of their sides is constructed for holding insulation piercing connecting devices and contact springs integrally connected to the latter, while the other side has correspondingly shaped integrally extruded pressure members which serve to press the connecting wires into the insulation piercing connecting devices, and the external plastic plates have on one of their sides either similar pressure members and press pins or receptacles on the other side, connecting devices and contact springs are held at a spacing inside a press tool by the press pins, which are designed with an interference fit, that connecting wires cut to length are inserted into these plastic plates preassembled at a spacing in the plug-in direction, and
The method according to the invention has the advantage that it is easy to carry out, since the use of special contacting tools and special crimping tools is eliminated.
In an embodiment, the method of the present invention includes the steps of providing a disconnected socket connector that comprises a plurality of adjacent plastic plates including a plurality of internal plastic plates arranged in a parallel and aligned fashion between a pair of opposing first and second external plastic plates. Each internal plastic plate comprises two opposing sides including a first side that is connected to a combination insulation piercing and connecting device that is connected to a contact spring. The first side further comprises a receptacle. The second side of each internal plastic plate comprises first and second integrally extruded pressure members and a press pin. The first external plastic plate comprises first and second integrally extruded pressure members and a press pin and the second external plastic plate comprises a combination insulating piercing and connecting device, a contact spring and a receptacle. The method further includes the step of providing a plurality of connecting wires, placing the connecting wires between two of said plastic plates so that each wire is in alignment with a combination insulating piercing and connecting device of one plastic plate and the first and second integrally extruded pressure
