Embodiment Construction

[0047] The high-voltage circuit breaker shown in section in FIG. 1 has a first contact piece 1 . The first contact piece 1 functions as a pin-shaped arc contact. The first contact piece 1 is arranged concentrically to the first axis 2 of the high-voltage circuit breaker. The first contact piece 1 is surrounded by a first rated current contact piece 3 . The first rated current contact piece 3 is likewise arranged concentrically to the first axis 2 . Socket-shaped arcing contacts 4 are arranged opposite each other along the first axis 2 . The socket-shaped arc contact piece 4 is arranged concentrically to the first axis 2 . The socket-shaped arc contact piece 4 is surrounded by a second rated current contact piece 5 . The first rated current contact piece 3 and the second rated current contact piece 5 are movable relative to each other along the first axis 2 so that the high-voltage circuit breaker shown in FIG. 1 in the on state can be switched into the off state. The sock...

Abstract

The first contact (1) and the second contact (13, 13a, 13b, 13c, 13d) constitute a contact device. The second contact piece (13, 13a, 13b, 13c, 13d) is fixed on one side and is reversibly deformable. In order to increase the pressing force of the second contact piece (13, 13a, 13b, 13c, 13d) on the first contact piece (1), additional pressing pieces (14, 15a, 15b, 15c, 15d , 22a, 22b). Furthermore, it is provided that a pressing force is generated by the pressing element (15d, 22a, 22b) and acts on the second contact element (13c, 13d) via the deflection device (16, 20a, 20b).

Description

technical field [0001] The invention relates to an electric contact device with a first contact piece and a second elastic contact piece, the first end of the second contact piece is clamped and the second end of the second contact piece elastically abuts against the first contact piece . Furthermore, the invention relates to an electrical contact arrangement having a first and a second contact piece, wherein the second contact piece is pressed against the first contact piece by means of a pressing piece. Background technique [0002] It is known, for example, to form a plug contact arrangement consisting of a pin-shaped contact and a socket-shaped contact. In this case, the socket-shaped contact is formed, for example, by elastic contact fingers which are elastically deformable when inserted into the pin-shaped contact and ensure an electrically conductive contact. [0003] Material wear occurs as a result of the relative movement between the contact parts of the electric...
