Multipole electrical connector

The invention relates to a multi-pole electrical connector with a plug-in part and a socket part, which with the Plug-in part can be connected in such a way that a plurality of plug-in ends and a plurality of contact sleeves, each of which is connected to its own conductor and secured with a latching connection, in mutual electrical contact can be brought, the plug ends being held at a mutual distance from one another by means of a first dielectric insulator and the sleeve contacts are kept at a mutual distance by means of a second dielectric 'see insulator.

A plug connection of this type is widely known. Known connectors, however, all suffer from the disadvantage that the sleeve contacts are much more expensive to manufacture than the plug ends, at least as far as these parts are on a lathe are manufactured.

The object of the invention is to create a plug-in connection with socket contacts that are considerably cheaper than known socket contacts

Sleeve contacts without affecting the quality of the contact pieces to be impaired, while at the same time as manufacturing advantages a simpler storage and easier storage should be achievable.

In the case of a plug-in connection, this task is described at the outset Art solved in that one of the contacts of the sleeve member, which can be connected to its own conductor is, consists of a plug-in contact and that the plug-in contact on its connecting part to the conductor is remote - the area is provided with a double-sided spring sleeve, which is in an extension of the second dielectric insulator for the sleeve contacts is included.

Further details, features and advantages of the invention emerge from the following description of an exemplary embodiment based on the drawing, in particular in connection with the additional claims. It shows

Fig. 1, greatly enlarged, a longitudinal partial section through an inventive Socket link,

FIG. 2 shows a section corresponding to FIG. 1 through a plug-in element which, in the manner indicated, is inserted into the socket element can be inserted according to Fig. 1,

Fig. 3 is a perspective view of a spring sleeve, the Part of the socket link is and

Fig. 4 is a perspective view of a sleeve-shaped Locking link.

In the drawing, A is the male link and B is the socket link each designated as a whole, of which only a small section is shown. The male member A has a Plug contact 1, which has a section 2 for connection to a conductor 6, a plug section 3 and an intermediate ♦ has lying shoulder 4. Section 2 on connection

with the conductor 6 is provided with a bore 5 into which the conductor 6 can be inserted. The connection between the conductor and the connecting section 2 can be known per se Way by soldering, clamping or in any other way. The plug-in part 1 is in a recess 7 of a dielectric Mounted insulator 8, which in turn is mounted in a housing not shown in detail. A lock 9 is inserted into the recess 7 and formed by a slotted sleeve that is bent inwards with Tongues 10 is provided, which by a snap or latching connection, the plug contact in one of its end positions locked. A rubber washer 11 or 12 is fastened to each surface of the insulator 8, which the plug-in section 3 of the plug contact or the conductor 6 enclose liquid-tight.

In order to simplify the sleeve member B as much as possible, both in terms of production technology and in terms of storage or use, the sleeve member has a number of individual features that are the same as that of the male member. The contact device, which is to be connected to the conductor 13 is therefore completely identical to the plug contact 1, which is used in the connector according to FIG. The plug contact 1 is therefore also essentially in one of the insulators 8 corresponding insulator 14 is arranged and the plug contact is also secured in position by means of the locking device 9. The insulator 14 is provided with an extension 15 in the form of a dielectric insulator body with a through-hole provided, which merges in the vicinity of one of the ends in a bore portion 17 of slightly smaller diameter, so that the transition between the two bores forms a shoulder 18. A sleeve 19 is arranged in the bore 16 and extends from shoulder 18 into a corresponding bore 20 in insulator 14. When the sleeve member is assembled, that is, the insulators 14 and 15 are joined together, for example by gluing, so that is formed in the bore 20

709814/0321

end face of the sleeve 19 extending into it has a stop for the shoulder 4 of the plug contact 1. The sleeve 19 is on the inside with a widened section 21 on that in the insulator provided lying end in which a double-sided spring sleeve 22 is arranged. The spring sleeve 22 is shown in Fig. obviously provided with axial slots 23 which merge into a larger opening 24 in the central region of the sleeve, whereby the residual material in the vicinity of the slots forms radially resilient tongues. The spring sleeve 22 is dimensioned and arranged in the sleeve 19, that it surrounds the plug-in section 3 over a little less than half its length.

Due to the construction explained, the manufacturing costs for the sleeve or socket member B can be compared to about 50% such sleeve members are lowered which have a rotated or inverted sleeve contact.

The assembly of the sleeve member can also be very simplified because the locking device 9 and the sleeve 19 with the Spring sleeve 22 can be easily inserted into the bores 20, 16 and 21, whereupon the insulators 14 and 15 firmly be connected to each other. The plug-in link 1 can thereupon through an opening 26 in the end disk 25 made of rubber, be inserted through a bore 27 in the recess 7 until the tongues 10 of the locking device 9 the plug contact hold correctly. The plug contact 1 can, if necessary, again in a manner known per se using a suitable tool can be removed from the recess.
