DE2804273A1 - COUPLING FOR ELECTRIC CABLES - Google Patents

Description

The invention relates to a coupling for electrical lines, consisting of a plug with a pin and a coupling socket with a correspondingly adapted socket, the pin and the socket each at the end of a single one electrical conductor are connected.

The coupling or the plug and the coupling socket are intended for a single line and can be used in conjunction with any electrical extension cables or on electromechanical devices are used and are in particular Suitable for electrical lines in motor vehicles or the like.

A coupling for electrical lines has already been proposed, Consists of a plug with pins or sockets that are cylindrical, parallelepiped-shaped, or flat are, and from a coupling socket with appropriately adapted sockets or pins that are attached to the ends of the electrical Conductors are clamped or soldered, the coupling socket and the plug each being formed from two parts, a part forms a body, the recesses each with a side opening for receiving a socket or a pin, and the other part forms a cap which is designed as an external protection and the sockets and holds the pins in position (German patent application P 28 01 090.4).

The object of the present invention is to install the pin or the socket in the plug or the coupling socket can without tools having to be used. In addition, the assembly should be easy and yet safe to carry out as well as ensuring a permanent connection and constant protection of the individual elements.

To solve this problem it is proposed according to the invention in the coupling explained in more detail at the outset that in the body of the coupling socket and in the body of the plug each have a recess for receiving the socket or the pin, which are held in position by means of wedge clips, hooks or paws.

This has the advantage that the socket and the pin can be installed particularly easily and one perfect arrangement without the aid of tools is attainable.

Advantageous refinements of the invention are specified in the subclaims.

In the drawing, three exemplary embodiments of the invention are shown, which are based on the following description are explained in more detail. It shows:

Pig. 1 shows a coupling socket 5 for receiving a socket 6 and a plug 8 for receiving a pin All elements are designed so that they can be brought into engagement with one another.

The coupling socket 5 has a body 11 and the plug a body 13 made of plastic and each having a central recess 14 and 15 into which in In the direction of the arrows 16 and 16.1, the socket 6 and the pin are inserted after the conductor cable 7 have been connected. The socket 6 and the pin 9 have bulges 17 and 17.1 that rest on shoulders 20 and 20.1, which are arranged facing inward on the body 11 and 13, respectively. The bulge 17 can also by a Punchings or projections are formed which protrude from the wall 6.1 or 9.1 of the socket 6 or the pin 9.

The body 11 and the body 13 each have a transverse groove 21, 21.1, the shape of which can be seen from FIG. These Transverse grooves open on the side wall of the bodies 11 and 13, and through their opening the wedge clamp 23, 23.1 is in Can be inserted in the direction of arrows 22, 22.1. A wedge clamp 23.2 can be seen from Fig. 2 and has the shape of a U, which partially encloses the socket 6 or the pin 9 at 24, 24.1, with deformations due to the elasticity of the plastic material are possible. The wedge brackets 23, 23.1 can move as soon as they are in their final position are located, no longer move out and lie in the longitudinal direction on the bulges 17, 17.1, whereby at the same time the socket 6 and the pin 9 are held in place.

The wedge clamps 23, 23.1 are attached to the bodies 11 and 13 by means of weak tongues 26 which are hinge-like are formed, thereby avoiding that the wedge brackets are lost. They can also be made in one piece be formed with the bodies 11 and 13, which is indicated in Fig. 2 by 23.2.

The body 13 partially covers the body 11 at 25, when coupled together and is held in position by lugs 30 which engage resiliently in grooves 31.

In the second embodiment according to FIG. 3, the Wedge clamp 23 replaced by one or more hooks 27, each with a head 28 on the bulge 17 is applied, whereby the socket 6 or the pin 9 is held in position. These hooks 27 engage at 27.1 on the Wall of the body and are by means of a constricted part 26 · in the form of a hinge on the other body attached.

In the third exemplary embodiment, the hooks 27 are supported by one or more elastic pawls 29 according to FIG. 4 replaced, which are formed directly on the wall of the body 11 and 13, the paws 29 projecting inward and hold the bush 6 or the pin 9 in position by moving back into their starting position, to block the bulge of socket 6 or pin 9. This fixation of the socket 6 or the pin can be improved by the fact that the inwardly facing surface of the bulge is a sharp-edged shoulder 17.2 is trained.

The coupling can also be designed for a line with several conductors, the line with several side by side arranged or opposite couplings is provided and the couplings have a common body

exhibit. In this case, the wedge brackets 23 for two or more adjacent sockets 6 and 9 pins are related.

The sockets 6 and the pins 9 can be cylindrical, parallelepiped-shaped or flat. the Recesses and the wedge clips are designed accordingly.
