Preferably, this contactor comprises many group moving contacts, and described many group moving contacts are connected with same action armature.
Preferably, between described moving contact and described action armature, be connected by a bolt, nut, on described bolt, be arranged with compression spring.
Preferably, one end of described action armature is connected with described back-moving spring, and the other end of described back-moving spring is connected with a bolt.
Preferably, also comprise an auxiliary switch and an auxiliary switch briquetting on this contactor, described auxiliary switch is relative with described auxiliary switch briquetting position, and described auxiliary switch briquetting is threaded with described action armature.
Preferably, this contactor also comprises arc control device, is provided with ceramic arc quenching plate in described arc control device.
As mentioned above, contactor of the present utility model has following beneficial effect: the action armature of this contactor is supported on support, in the time of contactor adhesive or disconnection, action armature will move up and down around this support, therefore require less to the suction of coil, contactor is just without larger coil is set like this, thereby can effectively reduce the volume of contactor, is convenient to the installation of contactor; There is again this contactor that contact is all arranged on same action armature, therefore can effectively ensure the synchronism of contact.

Embodiment
By particular specific embodiment, execution mode of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this specification.
Refer to Fig. 1 to Fig. 3.Notice, appended graphic the illustrated structure of this specification, ratio, size etc., all contents in order to coordinate specification to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this specification, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
As shown in Figure 1, the utility model provides a kind of contactor, this contactor comprises the parts such as action armature 1, coil 2, yoke 3, back-moving spring 5 and static iron core 7, coil 2 is positioned at yoke 3, static iron core 7 is positioned at a side of yoke 7, and the suction producing after coil 2 energisings can attract moving contact to move to static iron core 7.Action armature 1 is provided with moving contact, and this action armature 1 is supported on a support 4, and support 4 is provided with a through hole, and action armature 1 is mobilizable through through hole, and one end of action armature 1 is relative with static iron core 7 positions, and the other end of action armature 1 is connected with back-moving spring.Like this in the time that coil 2 is switched on, coil 2 will produce one end that magnetic attraction action armature 1 is relative with static iron core 7 positions near static iron core, and when after coil 2 power-off, one end that the armature 1 that moves is connected with back-moving spring 5 resets under the elastic force effect of spring.Seen from the above description, action armature 1, against support 4 rotary oscillations, therefore requires the suction of coil less, so just can effectively reduce the volume of coil, and then can reduce the volume of whole contactor.
As shown in Figure 3, contactor generally can arrange many group moving contacts 11, in order to ensure the synchronism of moving contact 11, moving contact 11 can be connected with same action armature 1, so only need an action armature just can drive many group moving contact synchronization actions, thereby ensure the synchronism of moving contact.
As shown in Figure 2, between moving contact 11 and action armature 1, be connected by a bolt 12, nut 13, on bolt 12, be arranged with compression spring, so just can reach by adjusting bolt 12, nut 13 object of controlled pressure spring pressure, and then the elastic force of controlled braking contact 11 own.The armature 1 that in like manner moves is connected with one end of back-moving spring 5, and the other end of back-moving spring 5 is connected with a bolt 6, enters by the pick-up voltage of adjusting bolt 6 capable of regulating contactors.
On this contactor, be also provided with an auxiliary switch 8 and an auxiliary switch briquetting 9, auxiliary switch 8 is relative with auxiliary switch briquetting 9 positions, by auxiliary switch 8 can detection contact whether adhesive.Auxiliary switch briquetting 9 is threaded with action armature, can be convenient to like this position of auxiliary switch briquetting 9 to adjust, and convenient contactor carries out assembly and adjustment.
On this contactor, also comprise arc control device, be provided with ceramic arc quenching plate 10 in arc control device, arc quenching plate employing ceramic material can be more high temperature resistant, can effectively extend the useful life of contactor.
The action armature of this contactor is supported on support, in the time of contactor adhesive or disconnection, action armature will move up and down around this support, therefore require less to the suction of coil, contactor is just without larger coil is set like this, thereby can effectively reduce the volume of contactor, be convenient to the installation of contactor; There is again this contactor that contact is all arranged on same action armature, therefore can effectively ensure the synchronism of contact.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
