Embodiment Construction

[0029] First refer to figure 1 , the electrical plug connector 1 comprises a coil spring 2 and a plug pin, in particular a plug pin 3 with a circular cross section. The coil spring 2 and the plug pin 3 are electrically conductive. By inserting the plug pin 3 into the coil spring 2, the circuit 4 can be closed.

[0030] Importantly, especially if figure 2 As shown, the coil springs 2 mostly have the same (inner) main diameter d h Circle 5. However, the coil spring 2 also has a contact ring 6 which has a contact dimension d which is smaller than the main diameter k . main diameter d k slightly larger than the outer diameter d of the plug pin 3, while the contact diameter d k smaller than the diameter d of the plug pin 3.

[0031] From figure 1 and 2 As can be seen in , with the same principal diameter d h The spring ring 5 includes some spring rings located in front of the contact ring 6 in the insertion direction of the plug pin, that is, on the right side of the co...

Abstract

The invention relates to an electric plug connection (1) with a plug holder (7) and a pin (3), especially a round-section pin (3), in which the plug holder (7) has a holding compartment in which is an axially compressible coil spring (2) having individual turns (5, 6) with the turns (5) largely having the same main diameter (dh). In order to reduce wear to the minimum even with frequent plug-in cycles and also not to increase the plugging force excessively, the invention proposes that the main diameter (dh) be larger than the outside diameter (d) of the pin (3) and that one or a few of the contact windings (6) have a smaller contact diameter than the main diameter (dh) and than the outside diameter (d) of the pin (3).

Description

technical field [0001] The invention relates to an electrical plug connector with a plug receiver and a plug pin, in particular a plug pin of circular cross-section, the plug receiver has a receiving chamber and a spring with its turns located in said Axially compressible coil spring in receiving cavity. Background technique [0002] An electrical plug connector of this type is known in the form, located in front of the coil spring in the direction of insertion, provided with a contact part movable axially in a receiving cavity, the plug pin and the contact during the insertion operation. parts in end-face electrical contact, see WO-A-86 / 01645. It is further known to provide a tubular plug receptacle with a coil spring fitted over its outer surface, one coil of which is threaded secantly into the plug receptacle through a hole in the plug receptacle internal. During the insertion operation, the plug pin is pressed against the inner surface of the plug receptacle by said c...
