Description
Technical field
The present invention relates to a kind of contactor that has the contact locking mechanism.
Technical background
Generally all be provided with the lockable mechanism that contact is supported on the existing contactor, after arc chamber unloads, can the contact support be pinned through lockable mechanism and not move.Lockable mechanism like the contactor of the patent No. 01804704.1 is to adopt the lever that rotates around yawing axis to be used as locking element; The mobile of this locking element needs guiding to move; Also just need yawing axis and guide mechanism well to cooperate to accomplish to move; Go wrong in case cooperate, locking element just can't lock the contact support, makes that the reliability of locking element is not high; And locking element remains on the bottom for what can not lose, need establish latch elements in addition locking element is installed on the bottom, and the space that takies the bottom is big, and cost is high.
Summary of the invention
There is not high, the problem big, that cost is high that takes up room of reliability in the lockable mechanism that the present invention will solve existing contactor, and a kind of reliability height, compact conformation, the contactor that has the contact locking mechanism that cost is low are provided.
Technical scheme of the present invention:
A kind of contactor that has the contact locking mechanism; Comprise pedestal, the arc control device that can pull down from pedestal; Contact support, locking mechanism are installed on the said pedestal, and said contact is supported in arc control device can be is characterized in that by the locking mechanism locking after pulling down: said locking mechanism comprises closing element; Said closing element is rotatably installed in the pedestal, and said pedestal is provided with the wall that ends with the motion of the underarm engagement limits closing element of said closing element; Said closing element comprises the upper arm that cooperates locking with the draw-in groove on contact is supported, is connected with the spring that drives its rotation on the side arm of said closing element, and the side arm of said closing element is provided with and cooperates first boss that upper arm is broken away from the contact support with arc control device.
Further, an end of said spring is connected on first spring base on the side arm of closing element, and its other end is connected on second spring base of pedestal.
Further, said closing element is provided with the rotation boss, and said rotation boss is installed in the swivelling chute of pedestal, and the radius of said swivelling chute is identical with the radius of rotation boss.
Further, the lower end of said closing element is provided with colludes, said collude with pedestal on second boss cooperate closing element be installed on the pedestal.
Further, said arc control device are provided with the casting die that cooperates with first boss.
Operation principle of the present invention: when arc control device are installed on the pedestal; The casting die of arc control device is pressed to first boss, and the side arm of closing element is moved downward, and the compression spring; Closing element moves around swivelling chute; Upper arm breaks away from from the draw-in groove of contact support, and contact support this moment just can proper motion, realizes the function of adhesive disjunction.
When arc control device when pedestal is pulled down, the effect that the side arm of closing element does not stress, under the elastic force effect of spring, closing element moves around swivelling chute, upper arm enters in the draw-in groove that contact supports, blocks the contact support.This moment is if the contact support is driven the words that move downward by electromagnet; The contact support just can be pressed to upper arm, gives power that moves downward of upper arm, but the underarm of closing element contacts with only wall on the pedestal; Closing element can not be rotated further, so upper arm just blocks locking with the contact support.
The present invention relies on the upper arm of closing element to cooperate the support of locking contact with the draw-in groove that contact is supported; The motion of closing element relies on the restoring force of spring and the casting die of arc control device; Closing element is to be installed in the swivelling chute through the rotation boss, and through the closing element lower end collude with pedestal on second boss cooperate and be installed on the pedestal, it can not broken away from from pedestal.
Beneficial effect of the present invention: simple in structure, locking is reliable, and it is little to take up room, and is practical firm.

Embodiment
With reference to accompanying drawing 1-4; A kind of contactor that has the contact locking mechanism comprises pedestal 7, the arc control device 14 that can pull down from pedestal 7, is equipped with on the said pedestal 7 that contact supports 12, locking mechanism; Said contact support 12 can be by the locking mechanism locking after arc control device 7 are pulled down; Said locking mechanism comprises closing element 1, and said closing element 1 is rotatably installed in the pedestal 7, said pedestal 7 be provided with 1 motion of the underarm of said closing element 16 engagement limits closing elements end wall 10; Said closing element 1 comprises with contact supports draw-in groove 11 on 12 to cooperate the upper arm 2 of locking; Be connected with the spring 13 that drives its rotation on the side arm of said closing element 1, the side arm of said closing element 1 is provided with and cooperates first boss 3 that upper arm 2 is broken away from contacts supports 12 with arc control device 14.
One end of said spring 13 is connected on first spring base 4 on the side arm of closing element 1, and its other end is connected on second spring base 8 of pedestal 7.
Said closing element 1 is provided with rotation boss 15, and said rotation boss 15 is installed in the swivelling chute 9 of pedestal 7, and the radius of said swivelling chute 9 is identical with the radius of rotation boss 15.
The lower end of said closing element 1 is provided with colludes 5, said collude 5 with pedestal 7 on second boss 16 cooperate closing element 1 be installed on the pedestal 7.
Said arc control device 14 are provided with the casting die that cooperates with first boss 3.
Operation principle of the present invention: when arc control device 14 are installed in 7 last times of pedestal; The casting die of arc control device 14 is pressed to first boss 3, and the side arm of closing element 1 is moved downward, and compression spring 13; Closing element 1 is around swivelling chute 9 motions; Upper arm 2 breaks away from from contact is supported 12 draw-in groove 11, and this moment, contact supported that 12 just can proper motion, realized the function of adhesive disjunction.
When arc control device 14 when pedestal 7 is pulled down, the effect that the side arm of closing element 1 does not stress, under the elastic force effect of spring 13, closing element 1 is around swivelling chute 9 motions, upper arm 2 enters into contact and supports to block contact and support 12 in 12 the draw-in groove 11.This moment is if contact support 12 is driven the words that move downward by electromagnet; Contact support 12 just can be pressed to upper arm 2; Give 2 one power that move downward of upper arm; But the wall 10 that ends on the underarm 6 of closing element 1 and the pedestal 7 contacts, and closing element 1 can not be rotated further, so upper arm 2 just blocks locking with contact support 12.
The present invention relies on the upper arm 2 of closing element 1 to support 12 draw-in groove 11 to cooperate the locking contact to support 12 with contact; The motion of closing element 1 relies on the restoring force of spring 3 and the casting die of arc control device 14; Closing element 1 is to be installed in the swivelling chute 9 through rotation boss 15, and through closing element 1 lower end collude 5 with pedestal 7 on second boss 16 cooperate and be installed on the pedestal 7, make them can be from pedestal 7 disengagings.
The described content of this specification embodiment only is enumerating the way of realization of inventive concept; Protection scope of the present invention should not be regarded as and only limit to the concrete form that embodiment states, protection scope of the present invention also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
