Contact (socket) piece for multi-pole plug connections

The innovation extends to a contact (Euchsen)

, .- piece for multi-pole plug connections with preferably

1/10 "contact spacing. There are already contact (socket) Pieces known for this purpose in the form of a shaft of rectangular cross-section with one at the end formed by several resilient tongues serving for the electrically conductive reception of a plug pin Socket part. With the known contact pieces this The spring tongues were made from the bent ends of two metal strips of constant material thickness formed, which were doubled in the shaft part and connected to one another by '- point welding or the like.

These contact pieces had no possibility of setting the contact pressure. The support of the spring tongues also took place to a large extent through the surrounding plastic, so that a certain risk d s opening of the connection points in the double-walled Shank part consisted. Finally, it is the capillary action of the gap between the two shaft halves Difficulties in making the soldered connections with the shaft parts "

The main task of the innovation is to provide a contact (socket) To create piece for the purpose described, in which the above-described disadvantages of the known Components are avoided. According to the innovation, this object is essentially achieved in that the shaft and the spring tongues from a single fork-shaped punched out and then stamped into the final shape Flat metal part consists of a U-shaped bent Transition point from the bent shaft to the tongue part. Such a configuration of the contact piece is on the one hand the risk of the socket part opening up due to the loss of any welded connection in the massive one Shaft part completely eliminated. Furthermore, the contact pressure can be adjusted by bending the U-shaped contact part accordingly adjust within wide limits.

Other advantageous features of the contact piece according to the innovation result from the associated claims for protection and the following description of an embodiment s example on the basis of the drawing with 5 illustrations. Of these show in detail:

advantageous embodiment of the innovation according to The contact piece is also a contact tongue 4 through a punched longitudinal slot 6 on the free The end is again divided into two spring tongues 7 and 8 of different widths, the longitudinal slot 6 Appropriate by asking the plastic question accordingly Deformation of the tongue 4 with a decreasing direction Width is provided. This increases the number of contact points and ensures reliable contact in a large frequency range of mechanical vibrations guaranteed by the different bending vibration natural frequencies of the contact blades.
