Problems solved by technology

The resulting continuous current carrying capacity via the coupling limits the maximum permissible rated current of the switching poles
[0004] The disadvantage of the known coupling device is that the heat dissipation is essentially only carried out by conduction of the flexible conductive strip, which conducts the heat generated at the first connecting part in the direction of the second connecting part

Embodiment Construction

[0022] 1 shows a perspective view of an exemplary embodiment of a coupling device 1 according to the invention, which has a clamping part 2 as a first connecting part and a stationary connecting part 3 as a second connecting part. The two connectors 2 and 3 are electrically connected to each other via two flexible conductive strips 4 .

[0023] The clamping part 2 has a clamping groove 5 for receiving a switching lever of a solid material insulated switching pole. In this case, the clamping part 2 has two parts 6 and 7 , the distance between which can be changed by means of a clamping screw 8 . The clamping part 2 can thus be firmly clamped to the switching lever by means of the clamping screw 8 . Furthermore, a cooling body 9 with cooling ribs 10 can be seen on the clamping part, which is thermally connected to the clamping part 2 and in this way increases the heat exchange surface of the coupling device 1 .

Abstract

Disclosed is a coupling device (1) for electrically connecting a first conductor to a second conductor. Said coupling device (1) comprises a first connecting piece (2) to connect the first conductor and a second connecting piece (3) to connect the second conductor. The first connecting piece (2) is joined to the second connecting piece via flexible connecting means (4) or sliding or rolling connecting means such that a relative movement can be performed between the first conductor and the second conductor. In order to create a coupling device (1) that features improved constant current stability while heating remains at the same level, a cooling unit is provided for cooling the coupling device.

Description

technical field [0001] The invention relates to a coupling device for electrically conductively connecting a first conductor to a second conductor, which has a first connecting piece for connecting the first conductor and a second connecting piece for connecting the second conductor, wherein the first connecting piece The second connecting member is connected to the second connecting member through a flexible connecting device, a sliding connecting device or a rolling connecting device, thereby allowing relative movement between the first conductor and the second conductor. [0002] Furthermore, the invention relates to a solid-insulated switching pole (Schalterpol), which has a non-conductive insulating material housing and a switching tube arranged in the insulating material housing, which is connected at the input connection to a stationary output Extending between the connection ends, an axially movable switching rod is used to introduce the drive movement into the switchi...
