Accompanying drawing explanation
Fig. 1 is the structural representation of the magnetictrip of this utility model chopper.
Fig. 2 is the sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings, by specific embodiment, the technical solution of the utility model is carried out clear, complete
Whole description.
Refer to shown in Fig. 1 and Fig. 2, this utility model provides the magnetictrip of a kind of chopper, including
Skeleton 1, coil 2, dynamic iron core 3, push rod 4, iron core spring 5 and static contact 6.
Described static contact 6 is for contacting or separate to realize being switched on or switched off of circuit with the moving contact of chopper.
Described coil 2 is sheathed on outside skeleton 1, and described static contact 6 is located at described skeleton 1 one end, described dynamic ferrum
Core 3 is located in described skeleton 1.Described static contact 6 includes canned paragraph 61, raised section 62 and contact section 63,
Described canned paragraph 61 is located at described skeleton 1 one end, and described contact section 63 connects described canned paragraph 61, described
Raised section 62 is protruded towards described dynamic iron core 3 by described canned paragraph 61.Described iron core spring 5 is held in institute
Stating between iron core 3 and described static contact 6, specifically, described iron core spring 5 is held in described dynamic iron core 3
And between described raised section 62.Described push rod 4 one end connects described dynamic iron core 3, and the other end is through described convex
Play section 62.Breaker mechanism action is made when described push rod 4 moves towards moving contact, so that chopper
Moving contact and static contact 6 separate, and circuit disconnects.When static contact 6 contacts with moving contact, circuit ON,
Normal circuit operation.When circuit is short-circuited, electric current is increased dramatically, under the electromagnetic force of coil 2,
Raised section 62 on dynamic iron core 3 and static contact 6 is attracting, and dynamic iron core 3 moves towards static contact 6 direction rapidly
Promote push rod 4 to move, make breaker mechanism action, so that moving contact and static contact 6 sharp separation, electricity
Road disconnects, to play the effect of protection circuit.The magnetictrip of this utility model chopper, static contact 6
Canned paragraph 61 be functionally equivalent to yoke of the prior art, raised section 62 be functionally equivalent to existing skill
Static iron core in art, contact section 63 be functionally equivalent to static contact of the prior art, say, that this practicality
Static contact 6 in novel has simultaneously worked as the effect of yoke of the prior art, static iron core and static contact, by
One parts instead of multiple parts, i.e. decreases amount of parts, and structure is simpler, easily fills
Join, and performance is more stable, and reduce cost.
Described raised section 62 is provided with through hole 602, and described push rod 4 is through described through hole 602, thus push rod 4
Breaker mechanism action can be moved such that through through hole 602, so that moving contact and static contact 6
Separate.
It is described fixing that described contact section 63 includes that stationary contact bar 631 and contact 632, described stationary contact bar 631 connect
Section 61, described contact 632 is located on described stationary contact bar 631.Specifically, described stationary contact bar 631 is in the form of a ring.
Described contact 632 is fixedly arranged on described stationary contact bar 631 by the way of welding or riveting.When static contact 6 He
During moving contact contact, contact 632 contact moving contact.
Described static contact 6 also includes that striking section 64, described striking section 64 connect described contact section 63, more
Body ground, described striking section 64 connects described stationary contact bar 631, and described striking section 64 plays the effect of arc ignition bar.
During assembling, described striking section 64 is installed on the side of the arc-chutes of chopper, 64 electric arcs of beneficially striking section
Quickly introduce in arc-chutes, reduce the energy that electric arc produces, reach the effect of fast arc extinction.
The canned paragraph 61 of described static contact 6, raised section 62, stationary contact bar 631 are integrated into striking section 64
Type, simplifies structure, reduces cost, and without being installed by modes such as riveting or welding, performance
More stable, simplify assembly technology.
