Abstract
The utility model discloses a breaker with a contact isolating device, which comprises an insulating shell, an operating executing mechanism, an electromagnetic tripping mechanism, an arc extinguishing mechanism, a movable contact and a static contact, wherein the operating executing mechanism comprises a handle, a handle connecting rod, a tripper and a lock catch. The breaker also comprises a contact isolating device which comprises a contact flash barrier, a flash barrier connecting rod and a rotating shaft supporting the linkage with the contacts, a swinging arm is fixedly arranged on the contact flash barrier, the head end of the swinging arm is rotatably arranged on the insulating shell, one end of the flash barrier connecting rod is rotatably arranged at the tail end of the rotating shaft and the other end is matched and linked with the contact flash barrier to form the operation for inserting the contact flash barrier and leaving between the movable contact and the static contact. The utility model has the advantage of being capable of immediately isolating arc generated by instant breaking of the movable contact and the static contact, thereby being capable of effectively protecting the movable contact and the static contact, avoiding continuous burning loss and improving the product breaking capacity.
Description
Technical field
The utility model relates to a kind of circuit breaker, specifically is meant a kind of circuit breaker with the contact spacer assembly.
Background technology
Existing miniature circuit breaker is made up of operating mechanism, tripping mechanism, arc-extinguishing mechanism, insulation crust, operating grip, dynamic/static contact etc., but the breaking capacity of the dynamic/static contact of traditional miniature circuit breaker is not enough, continue arcing product is destroyed, life of product is shorter.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and a kind of breaking capacity is strong, the circuit breaker of the band contact spacer assembly of long service life and provide.
For achieving the above object, the technical solution of the utility model is the contact spacer assembly, include insulation crust, operation actuator, electromagnetic trip mechanism, arc-extinguishing mechanism, and it is moving, fixed contact, described operation actuator includes handle, handle and connecting rod, tripping, snap close and contact support, also include the contact spacer assembly, this contact spacer assembly includes the contact flash barrier, flash barrier connecting rod and the rotating shaft that links with the contact support, be set with swing arm on the described contact flash barrier, and the head end of this swing arm is rotatable to be arranged on the insulation crust, the rotatable tail end that is arranged at rotating shaft of one end of described flash barrier connecting rod, the other end of this described flash barrier connecting rod and contact flash barrier are linked and constitute the insertion of contact flash barrier and leave moving, operation between the fixed contact.
Further being provided with is that described arc-extinguishing mechanism includes run-on tab and arc-extinguish chamber.
The utility model is rotatable the setting and contact flash barrier one interlock swing arm in insulation crust, increase the flash barrier connecting rod again, and with the rotating shaft of contact support interlock, rotating shaft is driven by the contact support, moving contact is during near fixed contact, rotating shaft drives the contact flash barrier by the flash barrier connecting rod and leaves between moving contact and the fixed contact, finishes dynamic/static contact contact conducting; During disjunction, rotating shaft drives the contact flash barrier by the flash barrier connecting rod and oppositely enters between moving contact and the fixed contact, cuts off the electric arc that disjunction produces, the breaking capacity and the useful life of having improved product.
The utility model has the advantages that can in time cut off dynamic/static contact disconnects the electric arc that moment produced, thereby can effectively protect dynamic/static contact to avoid continuing scaling loss, improve the product breaking capacity.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
