Abstract
The utility model provides an ultra -thin button movable contact spring control structure, installs in the base of ultra -thin switch and glues between the lid, including one be arranged in the base with glue can move about from top to bottom between the lid according to the handle and be fixed in the movable contact spring of base and the static contact that has the stationary contact, the movable contact spring has unsettled section of the elasticity that the tip was provided with the movable contact, at the pin that is provided with a horizontal extension according to the handle lateral wall, this pin blocks in unsettled section one side near the static contact of movable contact spring to make unsettled section to keeping away from static contact direction elastic deformation. The utility model discloses can guarantee to have improved the life of movable contact spring being pressed the in -process downwards and can cause the damage to the movable contact spring according to the handle, also increase feeling of button simultaneously.
Description
Technical field
The utility model relates to switching technique field.
Background technology
Existing ultra-thin key is and by handle pressing movable contact spring, movable contact spring distortion is contacted with static contact, realizes a some conducting.The movable contact spring initial condition of this class formation is free state, namely without distortion, the stroke that handle can press downwards is movable contact spring deformability scope, in pressing process, if firmly excessive fragile button or cause the irreversible deformation of movable contact spring, thus cause whole keys deactivation.
Utility model content
For the problem and shortage of above-mentioned prior art, the technical problems to be solved in the utility model is to provide a kind of ultra-thin key movable contact spring control structure with stroke protection, reliable in quality.
In order to solve the problem, the utility model realizes in the following way:
A kind of ultra-thin key movable contact spring control structure, be installed between the base of ultra-thin switch and glue lid, comprise one between base and glue lid handle movable up and down and be fixed on movable contact spring in base and there is the static contact of fixed contact, movable contact spring has the elastic suspended dead band that end is provided with moving contact, the pin of a horizontal expansion is provided with at handle sidewall, this pin is barred from unsettled section of movable contact spring near the side of static contact, and makes unsettled section to away from static contact direction strain.
As the improvement to such scheme, described handle moves down stroke and to be greater than on movable contact spring on moving contact and static contact spacing between fixed contact, is provided with and makes handle back-moving spring upwards between handle and base.
The utility model can ensure to be pressed downwardly in process the damage that also can cause movable contact spring at handle, improves the useful life of movable contact spring, too increases the feel of button simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment overall structure schematic diagram.
Embodiment
In order to allow those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further elaborated.
The ultra-thin key movable contact spring control structure that the present embodiment discloses can improve the useful life of button movable contact spring, increases handfeel of keys.Specifically as shown in Figure 1, the ultra-thin key movable contact spring control structure that this programme discloses is installed between the base 1 of ultra-thin switch and glue lid 2, comprise one between base 1 and glue lid 2 handle 3 movable up and down and be fixed on movable contact spring in base 14 and there is the static contact 5 of fixed contact 51, movable contact spring 4 has the elastic suspended dead band 41 that end is provided with moving contact 42, without in external force situation, the unsettled section of moving contact 42 made by himself elastic force of movable contact spring 4 realizes conducting with fixed contact 51 close contact.Separated in order to what make at initial condition moving contact 42 and fixed contact 51, the pin 31 of a horizontal expansion is provided with at handle 3 sidewall, this pin 31 is barred from movable contact spring unsettled section 41 side near static contact 5, and makes unsettled section 41 to away from static contact direction strain.Under initial condition, by the support of pin 31, unsettled section 41 is made to be out of shape, thus moving contact 42 is away from fixed contact 51, when pressing handle 3, unsettled section 41 loses support, under unsettled section of 41 its own resilient effects, moving contact 42 is contacted with fixed contact 51, realize conducting.
And, in this programme, handle 3 moves down stroke and to be greater than on movable contact spring 4 on moving contact 42 and static contact 5 spacing between fixed contact 51, and move down at handle 3 and make after moving contact 42 contacts completely with fixed contact 51, handle 3 still can continue to move down and can not affect the state of movable contact spring 4.Smooth and easy in order to make handle 3 reset, be provided with between handle 3 and base 1 and make handle 3 back-moving spring 6 upwards, back-moving spring 6 elastic force is greater than unsettled section 41 distortion elastic force.
It is more than the utility model preferably implementation; it should be noted that; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change and are out of shape the protection range that all should belong to the claim appended by the utility model.
Claims (2)
