Abstract
The utility model relates to a secondary plug-in protection device of a vacuum circuit breaker. The secondary plug-in protection device is characterized by comprising a protective cover (1), wherein the protective cover (1) is provided with an air vent (11); a U-shaped groove opening (8) is arranged at the upper side of the protective cover (1); and assisting grooves (10) are arranged at the left side and the right side of the protective cover (1). The secondary plug-in protection device is a disassembly-free protection device which can protect a secondary socket from being damaged and protect a wiring harness from being damaged when the vacuum circuit breaker is stored, transported and maintained, so that the use reliability of the vacuum circuit breaker is improved and the user management cost is reduced.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker secondary inserting piece protector.
Background technology
The Secondary socket of vacuum circuit-breaker is that vacuum circuit-breaker and switchgear assembly or microcomputer automatic protection system are electrically connected unique passage, has collected a large amount of linear quadratic controls and holding wire.Traditional vacuum circuit-breaker product is secondary inserting piece and wire harness, bellows exposed front upper at circuit breaker comprehensively, only does that some are simply fixing.Such design has the following disadvantages: vacuum circuit-breaker easily causes secondary inserting piece to damage in accumulating, maintenance process and the bundle of conics damage.
The utility model content
The purpose of this utility model is to provide a kind of vacuum circuit-breaker secondary inserting piece protector; can prevent vacuum circuit-breaker in accumulating, maintenance process; protection Secondary socket spare and wire harness, bellows exempt to dismantle protector, can realize the overall appearance, generous of vacuum circuit-breaker simultaneously.
A kind of vacuum circuit-breaker secondary inserting piece protector, its special feature is: comprise protective cover, have air vent hole on this protective cover, have U-shaped notch at the upside of this protective cover, all have the power-assisted groove on left side and the right side of this protective cover.
Wherein on the inner surface on protective cover left side and right side, adhesive magnet is installed all, thereby coordinates with the attraction iron plate of vacuum circuit-breaker corresponding position.
Wherein on the inner surface on protective cover left side and right side, the back-moving spring alignment pin is installed all, all is set with back-moving spring on each back-moving spring alignment pin, and at the other back-moving spring backing pin that coordinates with back-moving spring that also is equipped with of each back-moving spring alignment pin.
Wherein an end of back-moving spring alignment pin is fixedly connected with by pin with an end of protective cover connector, and the other end of protective cover connector is fixed on the protective cover inner surface.
Wherein air vent hole is a plurality of through holes that are distributed on protective cover.
Wherein be provided with ganoid U-type strip at U-shaped notch edges place.
The beneficial effects of the utility model are: the utility model provide a kind of at vacuum circuit-breaker in accumulating, maintenance process, can prevent that Secondary socket from damaging and the protector of exempting to dismantle of wire harness damage, improve the dependability of vacuum circuit-breaker, reduced the user management cost.
