Detachable electrical connection «

The invention relates to a releasable electrical connection with internal or external springing of at least one contact part that is exposed to higher temperatures "

The known releasable electrical connections, such as those for example with plug connections through the contact socket of the socket with the contact pin of the plug; elements by spring-loaded contacts with rigid contacts of the fuse or with lamp holder exi by under Spring-loaded contacts between the socket and the lamp base of the incandescent lamp or the contact pins of a fluorescent tube « lamps are large during their use. exposed to thermal loads, especially for longer periods of time Duty cycle and under the influence of higher currents, the temperatures occurring at the contacts can be very high be high.

In the case of the base contact materials used for these devices is due to an oxidation of the contact surfaces with a constantly increasing contact resistance at the contact point of contact to be expected. Depending on the place of installation and application, a strong layer of oxide can occur due to environmental influences. As long as this oxide layer as a result of the grinding holding movement

of the contacts during the maintenance process flawlessly is destroyed, the thermal load on the contacts can still be kept within tolerable limits for the material. For devices where the contacts »are constantly changing Current loads are exposed, such as plug connections and fuses in particular, but there is a risk that as a result Oxidation at higher current loads the contact heating increases beyond the prescribed level, so that the contacts through providers can come to a complete failure.

The invention has therefore set itself the task of doing this to provide an effective remedy.

The invention consists in that the actual contact element is formed in a self-resilient manner from bimetal or in the spring action of its contact surface is under the influence of a bimetal link.

Due to the deformation of the bimetal piece when the temperature rises, the contact pressure of the spring-loaded Contacts lenient it increased, so that an impermissible heating of the contacts, which lead to the destruction of the same could be excluded.

One is designed as a resilient contact socket Element comprised by a bracket formed from bimetal.

Another embodiment is an element designed as a contact pin with bimetallic strips that act in the radial direction Mistake.

According to a further embodiment, an element designed as a spring contact, for example in lamp sockets, formed entirely or partially from bimetal.

The invention is shown in the drawing in several exemplary embodiments shown. It shows:

Fig. 1 shows the basic principle of the electrical contact connection with bimetal,

Fig. 2 and J the formation of a Steekkontaktbuch.se with bimetallic clip,

FIGS. 4 and 5 show another embodiment of a plug contact socket with bimetal support,

6 and 7 the design of a contact pin with bimetallic strips, and

8 and 9 show an incandescent lamp socket Bimetal contact pieces.

In Fig. 1, the basic embodiment of the subject invention is shown. Here 1 is a fixed one Contact and 2 a contact strip fastened on one side against the contact 1, which can optionally be pressed on or off, which is connected to a.

Bimetal strip 3 is reinforced, the direction of action at Heating against contact 1 is directed.

In FIGS. 2 and 5, the contact socket 5 is on a base 4 and its connection terminal 5a attached. The contact socket 5 is provided with a clamp-like bimetal reinforcement spring 6 provided, whose direction of action results in a further compression of the contact socket 5 when the temperature rises.

In FIGS. 4 and 5, a contact socket 5 and its connection terminal 5a are fastened on the base 4, and on a plate 5b this contact socket are attached to bimetal supports 6, the direction of action when the temperature rises against one in the contact socket 5 introduced contact pin is directed.

In Figs. 6 and 7 is a bimetallic strip 8 used in eggs slot of the contact pin 7 whose direction of action runs in the radial direction of the round pin ¹ J. According to the invention, the bimetallic strip can also be attached in a tangential flattening of the contact pin 7, so that its pressure direction also runs in the radial direction when heated.

In FIGS. 8 and 9, the socket stone 10 is the incandescent lamp socket 9 provided with a center contact 11 and a side contact 12, which are formed directly from bimetal and whose The direction of action is directed against the lamp cap of the incandescent lamp 13 when the temperature rises. The center contact 11 as well

the side contact 12 is each provided with a connection terminal 11a or 12a for the lead wires. The middle contact 11 can be connected directly to the base of the incandescent lamp 13 or are in contact via a contact rivet 11b.

The present invention is not restricted to that stated in the description and in the exemplary embodiments Areas of application but can also be used with other devices, such as sockets for fluorescent tubes, Fuse bases, switching devices and the like are used.
