The invention relates to a sleeve for electrical connectors which is made of flat sheet metal and has been rolled into the shape of a tubular sleeve with an open longitudinal slot.

Electrical contact sleeves act like a spring bent in a 0-shape with two spring arms that are bent apart when the contact plug is inserted. Such sleeves, however, have the disadvantage that the material from which the sleeve is made is often elastically overstressed and this results in plastic deformation due to cold flow of the material, which then results in the

Einetβoken and to pull out the plug into the spring required force

However, such contact sleeves have the advantage that they only take up little space * and therefore two such contact sleeves can be arranged next to each other in an insulating block at a close distance from one another, so that a double-sleeve coupling results in cooperation with a contact plug pair, the Steoker pins of the contact plug pair may have a small distance from each other.

To the spring properties of such a contact sleeve one has to improve the open edges on the Hülsenachlitz bent inward and the connector pin inserted between the inwardly bent edges. With such a Embodiment of a plug-in coupling is based on the contact of the plug pin after insertion between the Case edges essentially only on the fire effect of this Edges, and thereby the connector pin is held in place; However, it is not to a significant extent the The spring property of the material forming the bottom of the sleeve is used. There is therefore the risk of overuse ' the material of the sleeve is lower, and the number of insertion and pull-out operations of the connector pin, which the sleeve has grown, is increased. However, this results in the

Disadvantage that the cross section of the sleeve is increased because between the inwardly curved edges of the slit and the side walls of the sleeve remain unused. ■

In general, contact sleeves of this type have a screw which penetrates the sleeve body as a connecting element, which is generally arranged at the point opposite the socket and serves the purpose of making contact with a wire or another conductor.

An electrical plug-in coupling made of sheet metal and bent into the shape of a tubular sleeve with a longitudinally extending shiita was characterized according to the invention in that only one edge of the material forming the sleeve into the

The space 9 between the spring 6 and the inner wall the sleeve 2 in the saw of the open edge 4 serves the purpose, that a contact et corner that is stronger than the »free space corresponds to is plugged in. Oa the spring part 6 in relation is biased on the Yandteil the main sleeve part 2, around which the spring part is bent, the plug pin feat held in the sleeve.

Because the contact spring 6 is formed in the sleeve 1, sioh shows that the velvet cross section of the sleeve is larger than the profile of the connector pin to be inserted. This is generally disadvantageous when it comes to the fact that two sleeves are arranged in an insulating block, so that they form a two-pole coupling, subject to the fact that the distance between the sleeves should be small; this problem but does not arise in the embodiment of the invention according to Pig. 2. Here it is assumed that the two sleeves 1, which correspond to the embodiment according to FIG. 1, are pressed into an insulating housing 10. The distance between the abutting edges of a double plug, which is to make contact with the sleeves, is A, and the axes the pins are spaced from each other B.

Figures 5-7 show a further modification of the Pig. 3 illustrated embodiment. The part of the sleeve from which the spring part goes out is slotted at 18 so that on Dumbbell two parts 19 and 20 are formed, which allow the connection of wires 21 and 22 of different diameters. Sin wire 21 of larger diameter is between the Kantelteil 19 and the spring part 6 included, while a wire 22 of smaller diameter between the jacket part 20 and the spring part 6 is included. To make it easier to insert the jbu wires, the ends open to the Receiving the wires provided parts at 24 and 25 funnel-shaped.

When a wire 22 of relatively small diameter is inserted into the rear part 20, the insulating jacket can lie within the front jacket part 19. Daduroh results in an enlargement of the pull-out of the connecting wire required force.

Ub to increase the force required for pulling out, transverse grooves can be provided on the casing parts 19 and 20 be. The two connector pins 15 of FIG. 5 are arranged on a strip 26 of a double connector and cooperate a double receptacle according to FIG. 2 together.
