Further, referring to Fig. 4, a kind of specific embodiment as four breakpoints contactor provided by the invention, institute
The bottom for stating the first atrium 61 offers the strip-shaped hole 611 passed through for the support side plate 57, the static contact component 2 and institute
The bottom plate for stating the first atrium 61 is fixedly connected, and the static gag bit 43 and the coil 42 are both secured to second atrium 62
Bottom.Specifically, the bottom surface of the first atrium 61, by 62 closure of openings of the second atrium, strip hole is arranged in the first atrium
61 bottom can pass through the strip hole by support side plate 57, to realize the fixation between moving armature 41 and dynamic touch panel 12
Connection.Static contact component 2 is that fixation member, contact supporting 5 and moving contact component 1 are mobile relative to static contact component 2, by stationary contact
Head assembly 2 and the fixed fixation that static contact component 2 both may be implemented of the first atrium 61；The static gag bit 43 and the coil 42
It also is fixation member, contact supporting 5 and moving armature 41 can be mobile relative to static gag bit 43 under the drive of the magnetic attraction of coil 42,
Fixation is can be thus achieved into the fixation of the first atrium 61 in static gag bit 43 and coil 42.
The working principle of four breakpoint contactors in above-described embodiment is as follows:
When four breakpoint contactors close a floodgate, coil 42 is powered, and 43 magnetic moving armature 41 of static gag bit moves downward at this time, drives touching
First 11 bracket 5 is moved downward across strip hole, and the second elastic component 55 is compressed at this time, four moving contacts 11 of moving contact component 1
It is in contact respectively with four static contacts 21 of static contact component 2；Then contact supporting 5 continues to move down, the first elastic component 53
It is gradually compressed, dynamic touch panel 12 is separated with the contact surface of contact supporting 5, at this time time of the first elastic component 53 and the second elastic component 55
Multiple power constantly increases, and finally keeps balancing with the suction of coil 42, at this point, generating between moving contact component 1 and static contact component 2
The excess of stroke and end pressure, moving contact 11 and static contact 21 can effectively close a floodgate.
When four breakpoint contactor separating brakes, coil 42 is powered off, and the magnetic attraction between moving armature 41 and static gag bit 43 disappears at this time,
Contact supporting 5 is moved upwards by the upward thrust of the second elastic component 55 along strip hole, at this time due to moving contact component 1 and quiet
There are the excess of stroke and end pressure between contact assembly 2, when contact supporting 5 moves upwards, the first elastic component 53 push dynamic touch panel 12 to
Lower movement, moving contact 11 still can effectively be connect with static contact 21 at this time, until, the upward power of contact supporting 5 is greater than the first bullet
The power that property part 53 pushes down on, so that the separation of moving contact 11 and static contact 21, finally realizes the separating brake of four breakpoints.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
