Connector for connecting two cable ends Description:

The invention relates to a connector for connecting two cable ends according to the preamble of claim 1.

The demands of the energy supply companies for assembly-friendly Components for your cable networks have pushed connectors more and more to the fore in recent years. The plug connectors offer the advantage that the conductors are connected in a fully insulated and encapsulated housing can remain free without mounting openings. This is e.g. at prefabricated one-piece sleeve bodies necessary where contact the ends of the conductors in the middle of the muff.

There are already plug connectors whose contact surfaces with Contact lamellas are provided (prospectus SIG ... AE-N No. 08.73 and B ... AR-N No. 280272.01 from Finra Multi-Contact) lamellae also generate the necessary contact pressure. The interlock required in some situations is through achieved a slotted spring washer arranged in the socket. The spring ring spreads when the plug is pushed in and snaps in the end position in one located on Steckeren.de Groove a. If it is necessary to loosen the connection, i.n the Plug groove arranged a movable in the axial direction iiohrstück be.

In this and other similar connectors, only one plug protrudes into a socket. The contact area is therefore relatively small and the transition resistance is relatively high.

The contact surface can also be made through a large socket bore enlarge only within certain limits, for example. if the plug contacts should still be usable for one-piece, prefabricated sleeves. As is known, this type of sleeve must have a predetermined Tension sitting on the inner cable. Of the The maximum diameter of the plug connection can therefore only be in this bracing range. As an alternative, there is to lengthen the connectors. An enlargement of the contact area is of course also achieved in this way. However, that meant that not only more material has to be used for the connector, but also for the extended sleeves.

What was previously described for the socket also applies, of course for use in switchgear. The trend towards miniaturization of these systems, which has been going on for a long time, is enhanced by extension however, the plug is by no means taken into account.

There is also known a connector in which a slotted Bushing used by a heat resettable

the metal sleeve is surrounded (DE-AS 22 52 441). Through / heat resettable The metal sleeve becomes the resilient one due to the heat shrinkage Metal sleeve pressed against the connector pin. All known connector systems have the common feature that their contact is via a socket is achieved with a plug connection bolt.

Such a plug connection can be the heat supply required after the connection for encapsulated sleeves or However, do not use plants.

The invention is therefore based on the object of a connector to create that has a much better contact behavior than previous connectors. The contact area should be however, are enlarged so that the external dimensions of the connector are essentially retained.

According to the invention, this object is achieved by the structural measures specified in the characterizing part of claim 1.

The advantages achieved by the invention are that the arrangement of several sockets / plugs into each other Contact area is increased significantly without this having any effect on the external dimensions. It is thus guaranteed that the connector can be used in all prefabricated and encapsulated cable fittings. The trimmings need it not to be enlarged, which avoids additional expenditure on material and takes miniaturization into account.

Advantageous designs and developments of the subject matter according to the main claim are contained in the subclaims. Here the socket bores of the contact parts have resilient contact elements on (claim 2). Furthermore, both contact parts are provided with latching elements that provide a reliable latching connection enable (claim 3). It is also possible to design at least one contact part in an angular shape, thus increasing the diversity the possible uses is underlined (claim 5).

An embodiment of the invention is shown in the drawing and is described in more detail below. Show it:

Fig. 1 the one contact part of the connector, in section. Fig. 2 the other contact part of the connector, in section

FIG. 3 shows an angle plug-in part that matches the contact part of FIG. 1? Connector, in section.

According to Fig. 1, the connector consists of a contact part 1 with a relatively large socket bore 1a. In the central axis A bolt 1b is arranged in this bushing bore. In the Socket bore are resilient contact elements 1c. In the end if the socket bore near the opening has a spring-loaded

the ring 1d. The end of the facing away from the contact area Contact part has a further bore 1e for receiving the to be connected Head.

In Figure 2, the contact part 2 is shown, which to the contact part 1 corresponds. This contact part has a plug 2a which is provided with a socket bore 2b. The inside of the socket bore is in turn equipped with resilient contact elements 2c. An axially movable ring 2d at the end of the contact part 2 forms a corresponding latching connection with the resilient one Ring 1d of the contact part 1. This is also from the contact area The opposite end is provided with a hole 2e, which is used to accommodate the conductor to be connected.

According to FIG. 3, the contact part corresponding to the contact part 1 is shown 3 executed in an angular shape. The plug part 3a has a Socket bore 3b, which in turn has resilient contact elements 3c is equipped. The other end of the contact part contains a socket bore 3e for receiving the conductor to be connected.

Such a connector can be used as a connecting element in all Areas of electrical engineering. It can also be used to connect terminations instead of a screw terminal.

Its special area of application, however, is fully encapsulated Components such as sockets and connectors for switchgear and transformers.
