Definitions

• the invention relates to a contact socket with elastic locking tabs intended to retain the captive socket in an insulating support housing.
• Such sockets are usually formed by a ferrule obtained by rolling a metal blank and having a longitudinal joint. These sockets thus comprise, from one edge to the other of the joint, an arrangement of contact tongues or strips and of locking tongues cut from the ferrule. But the cutouts are such that the contact tabs or strips and the locking tabs are either arranged successively along the bushing, which makes it possible to give them good mechanical strength but requires considerable space, or are placed side by side at mime level, which gives a reduced bulk, but is accompanied by precarious mechanical strength.
• the object of the invention is to provide a contact sleeve obtained by rolling, having a reduced bulk, but offering good mechanical strength in the presence of the longitudinal forces which it is called upon to undergo.
• the subject of the invention is a contact socket with locking tabs intended to retain it in the housing of an insulating support, said socket comprising a ferrule formed by rolling a metal blank and having a joint longitudinally, at one end a collar intended to be connected to an electrical conductor and at the opposite end an entry for a contact plug, characterized in that it comprises two elastic locking tabs cut out along the shell, framed by cutting slots, said tabs being adjacent to the entrance and slightly apart from the collar, and being separated from each other, on an inner side by an internal contact strip connecting the collar to the entrance, and on the other outer side for one of the tabs locking by an external contact strip connecting the collar to the inlet and for the other locking tab by a tab external contact adjoining the collar and separated by a cutout from the inlet, the external contact strip and the external tongue being arranged facing the joint of the ferrule.
• the internal contact strip is substantially arranged diametrically opposite the joint of the external tongue and the external contact strip and on the other hand the locking tabs are substantially arranged in opposition according to a diametral plane.
• the entry comprises a chamfer, which can be obtained by striking.
• Figure 1 is a perspective view of the socket according to the invention.
• FIG. 2 represents a developed view of the sleeve, constituted by the blank cut from which it is obtained.
• the ferrule of the sleeve is designated by 1, the edges 11 and 12 of which give rise to the longitudinal joint 10 visible in FIG. 1.
• the ferrule comprises at the lower part an inlet 2 intended for the insertion of a contact pin and at the upper part a collar 3, the extension of which successively comprises, in known manner, locking stops 31 intended to retain the socket in the housing of an insulating support, crimping tongues 32 of a conductor to connect and crimping tongues 33 of the insulating sheath of the conductor.
• the socket 1 has two locking tabs 4 and 5 cut longitudinally and adjoining the inlet 2. These tabs 4 and 5 are framed by longitudinal cutting slots such as 41 and 51, visible in FIG. 2, as well as slots transverse cutting such as 42 opposite the collar 3.
• the tongues 4 and 5 are separated from each other on an internal side by an internal contact strip 6 and on the external side for the tongue for locking 4 by a contact strip 7 and for the locking tab 5 by a contact tab 8.
• the contact strips 6 and 7 connect the inlet 2 to the collar 3, while the contact tab 8 is attached to the collar 3 but separated from the inlet 2 by a cutting slot 80 adjoining the slot 51 and separating it from the end 23 of the inlet 2.
• the outer edges of the strip 7 and of the tongue 8 are arranged facing the right of the longitudinal joint 10. But the contact strip 8 has, at the right of this joint, a longitudinal cut 70 which leaves an end 22 on the entry.
• Entrance 2 comprises a chamfer 21.
• a socket can be easily obtained first by cutting out a blank such as that shown in FIG. 2, then by bending the tongues and finally rolling to form the ferrule.
• the chamfer 21 can be produced directly by striking before rolling.
• the cutouts of the tongues and strips in the blank are made so that after rolling on the one hand the internal contact strip 6 is substantially arranged opposite the diametrical plane passing through the longitudinal joint 10 and that the tongues elastic locking devices 4 and 5 are arranged substantially in opposition along a diametrical plane.
