Abstract
A vacuum contactor includes a stationary contact and a moving contact, which can be moved in order to produce a current-carrying connection. In order to guide the moving contact during its movement in the enclosure, at least one guide element, which can be moved in a groove, is provided on the moving contact.
Claims41
A vacuum contactor, comprising:
- a stationary contact;
- and
- a movable contact, movable to produce an electrically conductive connection, wherein the movable contact is connected to an enclosure of the vacuum contactor such that it can be moved;
- and
- a bellows element, located between the stationary contact and the movable contact, wherein the movable contact includes at least one guide element, movable in a groove in the enclosure, the groove being formed by interaction of at least one recess in at least one of the enclosure and a cover of the enclosure, and at least one contact surface on at least the other of the enclosure and cover of the enclosure, and wherein the at least one guide element is fitted on an annular element of the movable contact of the vacuum contactor, wherein the annular element is fitted adjacent to the bellows element, and wherein the annular element includes a projection for positioning of an angled element for fitting a flexible strip on the movable contact.
2 more elements
A vacuum contactor, comprising:
- a stationary contact;
- and
- a movable contact, displaceable to establish an electrically conductive connection, wherein the movable contact includes at least one guide element, movable in a groove formed by at least one recess in at least one of a housing of the vacuum contactor and a cover of the vacuum contactor, and at least one contact surface on at least the other of the housing of the vacuum contactor and a cover of the vacuum contactor a cover of the housing, and wherein an annular element of the movable contact includes a projection for positioning of an angled element for fitting a flexible strip on the movable contact.
A vacuum contactor, comprising:
- a stationary contact:
- and
- a movable contact, displaceable to establish an electrically conductive connection, wherein the movable contact includes at least one guide element, movable in a groove formed by at least one recess in at least one of a housing of the vacuum contactor and a cover of the vacuum contactor, and at least one contact surface on at least the other of the housing of the vacuum contactor and a cover of the vacuum contactor. wherein the at least one guide element includes opposing guide elements.
