Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is an electrical connector strip having a plurality of contact members to which the core wire of an electrical switch cable can be connected. , the contact member is fixed to an insulator and extends through the insulator, and an end of the contact member opposite to the switch cable has a terminal slit opened toward the end surface. A press-fitting member for fixing the core wire can be mounted on the insulator, and the press-fitting member allows all of the insulated core wire ends to be press-fitted into the terminal slit at the same time. Concerning the type of thing that is.

BACKGROUND OF THE INVENTION A connector strip of this type is known, for example, from German Patent Application No. 1765512. The end of the contact member opposite the switch cable is adapted to be inserted into a hole in the electrical conductor plate and can be connected to the conductor plate by brazing. The end facing the switch cable is designed as a disconnection terminal with a terminal slit open toward the end face. The ends of the core wires of the multipolar switch cable can be fixed to a press-fitting member with a self-adhesive layer for proper connection. The press-fitting member is inserted together with the bonded core wire end through the cutting terminal. At this time, the core wire is pushed into the terminal slit of the cutting terminal and comes into contact with the cutting terminal. The press-fit member has an end-side locking element that snaps into a corresponding counter-locking molding of the insulator.

SUMMARY OF THE INVENTION The problem that the invention seeks to solve is to improve an electrical connector strip of the type mentioned at the outset to increase the reliability of the position of the core end in the press-fit element.

Means for Solving the Problems A configuration of the invention which solves the above-mentioned problems is such that the press-fitting member has a fixing slit for the core wire and has longitudinal webs projecting laterally, the longitudinal webs being It partially surrounds the insulator.

Effects of the Invention The core wire is reliably held in the transverse direction within the fixing slit of the press-fitting member. If the fixing slit is suitably dimensioned, the core wire can be firmly clamped in such a way that it is held very reliably in the longitudinal direction. This made it possible to expose the cable with the core end fixed to the press-fit member to transport instability. That is,
This means that the cable can be prepared for transport in a specially prepared work area, where the core wires can be pre-sorted and held to ensure correct connection.

The laterally projecting longitudinal webs of the press-fit element securely fasten it to the insulating element over a large area, so that even outwardly acting forces can no longer threaten the electrical connection.

Embodiment According to an embodiment of the invention, the longitudinal web is formed with a flat locking element which snaps into a corresponding relief-like counter-locking molding of the insulator. ing. By locking on the longitudinal side of the connector strip, the change in position of the opposite side is slightly reduced in the event of bending. Furthermore, the space requirement for such a locking element is extremely low.

According to the exemplary embodiment shown in FIGS. 1 and 2, a row of contact elements 2 is inserted into a strip-shaped insulator 1. In FIG. This contact member 2 projects from both sides of the insulator 1.

On the side facing the switch cable 3, the contact element 2 has a terminal slit 4 which is designed as a disconnect terminal and is open towards the end face. . The insulated and freely extending end of the core wire 5 of the switch cable 3 is press-fitted into the terminal slit 4 to be brought into contact with the contact member 2 .

The opposite end of the switch cable 3 is inserted into a hole in the conductor plate 6 indicated by a dashed line and connected to the conductor plate 6 by, for example, brazing.

The end of the core wire 5 is held in a fixing slit 7 opened toward the insulator 1 of a press-fitting member 8 made of plastic. By lowering the press-fitting member 8 in the direction of the illustrated arrow, the end of the core wire 5 is brought into contact with the contacting member 2. The press-fitting member 8 has a recess 9 for the contact member 2 . The longitudinal webs 10 of the press-in part 8 projecting laterally toward the insulator 1 grip the insulator 1 over a large area from its periphery after connection. A spring-elastic locking element 11 is integrally molded onto the longitudinal web 10 and cooperates with a corresponding relief-shaped counter-locking profile 12 of the insulator 1 .

Further, a narrow horizontal rib 13 is integrally formed in the fixing slit 7, and the core wire 5 is fixed at a position where it bites into the insulating part of the end of the core wire. The conductor plate 6 can receive a number of connector strips made up of insulators 1 , contact elements 2 and press-fit elements 8 for a plurality of switch cables 3 . If the number of core wires of the switch cable is suitably large, the core wires can be fixed to a plurality of press-fit members or to multiple rows of press-fit members. A plurality of insulators having contact members are assigned to the plurality of rows of press-fit members. The connector strip includes a plurality of rows of press-fit members;
and a plurality of insulators having contact members.

The insulator 1 with the contact elements 2 is brazed to the conductor plate 6 before the core wire 5 of the switch cable 3 is connected. This switch cable 3 is cut at a different location and its exterior is removed. Sorting and fixing the core wires 5 to the press-fitting members 8 can also be done at this separate location. Since the fixation is reliable, the switch cable can be exposed to the load during transportation as it is by means of the press-fit member.
