Abstract
Disclosed is a tulip contacting device for a vacuum circuit breaker employed to quickly break off an electric power system, in which contact fingers are bidirectionally rotatable in a state of being restricted at an outer diameter portion of a mover holder, such that the flexibility of the contact fingers can be increased, whereby it is possible, upon connecting the vacuum circuit breaker to a case, to flexibly deal with the variation of axial angles of terminals inserted in both sides of the tulip contacting device, and also springs may be coupled to the contact fingers, respectively, so as to effectively prevent separation and overall destroy of the contact fingers from the mover holder during installation.
Claims9
A tulip contacting device for a vacuum circuit breaker, comprising:
- a plurality of contact fingers disposed in a circumferential direction so as to allow an insertion of terminals;
- a mover holder having through holes formed in a circumferential direction, each contact finger being inserted and restricted in the corresponding through hole;
- and
- movable springs coupled onto the contact fingers in the through holes of the mover holder and configured to provide an elastic force to the contact fingers,
- wherein the mover holder is provided with a circular plate inserted in the contact fingers so as to restrict a lateral movement of the contact fingers.
