Description

GERMAN

The invention relates to an electric stocker and has the object of providing a. and to make the same plug-in device usable for different purposes by converting or replacing the contact pieces and at the same time to ensure that three externally completely identical, because of their different, inner ones. However, the construction of plugs and sockets for different purposes can be used unmistakably. There are already plug before directions with blade contacts, and uniqueness device known, the connector housing in the plane of its end face with one or more 'hook-shaped. Approaches is provided on one or more, arranged in the socket housing. Axes are hooked. It is disadvantageous that the device against: unintentional joining together of the connector parts must be provided during the manufacture of the connector. The approaches on the plug and the attachment of the guide slit in the socket housing must therefore be specified in terms of manufacturing, and a subsequent change is not possible. Special components are therefore required in each case for different: fuse systems in the plug connection. Another well-known version has a distinctive one! Plug contact with concentrically arranged current connection pieces, in which the corresponding cylindrical surfaces of the junction box and plug are provided with radially arranged projections. Here, too, a different arrangement of the locking members is required for each security system, which must also be taken into account during the manufacture of the connector parts and. universal use of the plug-in device for various ¹ security systems is therefore not permitted. With such devices it is possible in many cases to create a plurality of distinctive arrangements by exchanging the components that determine the security system, but these methods require additional components in the form of special adapters.

In contrast, the invention is characterized in that that to avoid the unintentional joining together of not belonging together Plugs; and sockets · on which one plug part is subsequently provided with removable lugs and the other plug part has a convertible to be fastened locking member that when joining the Plug part of the gap of each removed. Nose facing.

This makes it possible for all purposes the plug-in device · can be manufactured completely identically. With cylindrical training the plug can be connected to its outer circumference with an electrical plug-in device

The number of exchangeable contact pieces corresponding to the number of poles required in each case. Mistake. ¹ and as a locking member on its end face a Beifestigungspla.tte with a radially adjustable locking lug, which interacts with a number of atisbreakable lugs provided on the inner edge of the socket and corresponding to the largest number of poles of the plug.

A. Embodiment of the invention is shown in the drawing, namely shows

Fig. 1 the connector and

Fig. 2 shows the associated socket in longitudinal section, while

Fig. 1 a shows a cross section through the cylindrical plug and

Fig. 2a shows a cross section through the upper edge of the socket;

Fig. 3 shows a further view of the plug-in device, partially in section.

The plug consists of the sleeve-shaped handle 1 and the cylindrical plug insert 2, both made of insulating material, in particular molded material or injection molding. Located along the mamtellinie in the insert 2 grooves into which the contact pieces 3 of U-shaped cross-section are embedded, which at Pushing the plug into the socket 5 brings about a conductive connection with the contact pieces 6. the Springs 6 can be loosely inserted into the socket and are then fixed using a pin screw ube7. Included the stud screw is also used to fasten the one brought to the socket from the outside Wires; instead, the connecting wires can also be connected to the lower one serving as a soldering lug 6 α End of the contact spring 6 are soldered. The inlays, 3 of the connector neck also have Solder connections 3 α, which are accessible from above,

Is at the 2 Stecketreinisatz a Führungsnaise 2 a, soft in serving as a straight guide recess 5 'of the socket fits. Plug and socket can, that is to say, always only be joined together in a precisely centered position, whereby they can be pushed into one another until the guide nose strikes the lower edge of the recess 5α. In the exemplary embodiment, the plug insert has a total of five U-shaped contact pieces 3. The contact piece is omitted at point 3 '. Correspondingly, lugs 5 & are provided on the inside at the upper edge of the socket, with bsi 5 ', however, a lug has been removed. The wetness is relatively small and can be broken away with pliers as required. By inserting the springs. 6, the plug can be equipped with a single pole or any number of poles, a total of six poles, so that it can be used in many ways in practice. In order to ensure that only the correct pair can be uniquely joined together from the outwardly identical sockets and plugs, one of the noses 5b, for example the one at 5 ', is broken away. At the same time, a 'plate 8 with locking lug 8' (cf. also Fig. 1 a) located on the front side of the plug insert is used as a locking member relative to the guide lug 2 α that fits in 8 'when inserting the socket into the socket. the point (5 ') is where <before the nose 5 ?; has been removed. If the extension plate 8 and the gap 5 'are not on the same pitch, the plug and socket cannot be joined.

From Fig. 3, which shows a view or a longitudinal section of the switching device, which are rotated by 90 ° with respect to the section according to FIGS. It has a push button 10 a protruding through a circular opening in the sleeve and below a retaining lug 10 b which, after the plug parts have been plugged into one another, engages behind the web 11 provided on the socket 5 under the action of the spring 12 and. then the. Secures the plug against unintentional pulling out.

In principle, it would also be possible not to break off the lugs S b , but to make them screw-on, in order to keep the sockets usable repeatedly for different equipping and purposes.

Claims (3)

Patent claims: 1. Electrical plug-in device with protection against unintentional assembly of not matching plugs, and. Sockets, thereby characterized in that on the one plug part subsequently removable noses are provided are and the other plug part has a repositionable to be fastened locking member, which when joining of the plug part · faces the gap of the respectively removed nose. 2. Plug device according to claim 1, characterized in that the cylindrical plug on the Scope with an interchangeable number corresponding to the number of poles on the connector. Contact pieces can be provided and on its front side carries a locking plate with a radially adjustable locking lug that is connected to the Inner edge of the socket provided lugs cooperate, the number of which corresponds to the number of poles of the plug corresponds and of which the locking nose, the Locking plate opposite removed, especially! aborted. 3. Plug device according to claim 1 or 2, characterized in that the plug with a Holding lug is provided to prevent unintentional pulling out of the socket, which is behind a, the web provided for this purpose engages in the socket.
