In order to keep the following explanation of the utility model to understand and concise, be omitted in specific embodiment known function and
The detailed description of known elements.
As shown in Fig. 1~5, the load switch structure of the utility model, including quiet conductive sheet 1, moving conductive piece 2, movable plate group
Part 3 and push card 4, the rear end of the movable plate component 3 are fixedly connected with the moving conductive piece 2.
The movable plate component 3 offers open slot 300 along its length, and the open slot 300 divides the movable plate component 3
It is divided into movable plate bar 31 and lower movable plate bar 32, is respectively arranged with movable contact 30 on the upper movable plate bar 31 and lower movable plate bar 32.Institute
Stating movable plate component 3 can be constituted using the movable contact spring of monolithic, can also be using as shown in the figure by the first splitter 301 and second
Splitter 302, movable contact spring 303 are sequentially stacked.
The quiet conductive sheet 1 is equipped with stationary contact 10 corresponding with the movable contact 30, and the push card 4 can drive institute
Movable plate bar 31 and lower movable plate bar 32 are stated to the direction movement close to or far from the quiet conductive sheet 1 so that 30 He of movable contact
The contact of stationary contact 10 or separation, realize being switched on and off for load switch.
The front end of the upper movable plate bar 31 is provided with extension 311, and the front end of the lower movable plate bar 32 is provided with elastic slice 5
And the lower extension 321 extended to form is bent to close to the upper extension direction.The lower extension 321 with it is described lower dynamic
The junction of piece bar 32 uses arc transition, fatigue fracture caused by stress concentration is avoided, to increase the machinery of product
Service life.
Card slot 41 is provided in the push card 4, the card slot 41 has the first side wall close to the quiet conductive sheet 1
411 and far from the quiet conductive sheet 1 second sidewall 412, the upper extension 311, lower extension 321 and elastic slice 5 can be set
In the card slot 41, the upper extension 311 and lower extension 321 are abutted with the first side wall 411 of the card slot 41, the bullet
Piece 5 is abutted with the second sidewall 412 of the card slot 41.It is mobile to the direction far from the quiet conductive sheet 1 when the push card 4
When, the push card 4 applies active force to the upper extension 311 and lower extension 321, drives the upper movable plate bar 31 under
Movable plate bar 32 is mobile simultaneously, makes the movable contact 30 on the upper movable plate bar 31 and lower movable plate bar 32 simultaneously and on quiet conductive sheet 1
