Utility model content
The purpose of this utility model is to provide the more rational push-button switch of a kind of structure, and the upper cover of this kind of push-button switch is fixedly connected with very reliable with base, have good result of use.
The technical scheme that realizes the utility model object is:
A push-button switch, comprises the housing being connected and composed by upper cover and base, and described base is provided with two the first terminals and three the second terminals;
On described base, form the first joint pin and the first connecting hole; On described, cover and form and the second connecting hole of described the first joint pin interference fit and the second joint pin coordinating with described the first connecting hole, the part that described the second joint pin extends to described outside through described the first connecting hole forms fusion-welded portion.
In technique scheme, described the first terminal and described base are injection molding type integrative-structure, and described the second terminal is inserted in the jack of described base.
In technique scheme, described base inside forms for spacing to prevent the positive stop lug boss of described the second terminal bends to described the second terminal.
In technique scheme, the both sides of described the second terminal form evagination limiting section, form the slot that coordinates further to prevent described the second terminal bends with described evagination limiting section on the inwall of described upper cover.
In technique scheme, described base exterior and described the first connecting hole correspondence position form groove, and the axial length of described fusion-welded portion is not more than the axial depth of described groove.
The utlity model has positive effect: (1) push-button switch of the present utility model is fixedly connected with upper cover and base except the first joint pin is set with the second connecting hole interference fit, also be provided with fusion-welded portion, after described fusion-welded portion melting welding, described upper cover further can be fixedly connected with base, very reliable by adopting above-mentioned two kinds of fixed connection structures that upper cover is fixedly connected with base, both can delamination after fixing, has good result of use.(2) in push-button switch of the present utility model, by positive stop lug boss being set and at the both sides of described the second terminal moulding evagination limiting section, and the slot that setting coordinates with described evagination limiting section on upper cover inwall, by adopting said structure can effectively prevent that the second terminal bends is out of shape, thereby guarantee that product has good result of use.

Embodiment
Below in conjunction with Figure of description, the structure of push-button switch of the present utility model is elaborated:
With shown in Fig. 5, a kind of push-button switch, comprises the housing being connected and composed by upper cover 1 and base 2 as shown in Figure 1, Figure 2, and described base 2 is provided with two the first terminals 3 and three the second terminals 4; On described base 2, form the first joint pin 21 and the first connecting hole 22; On described upper cover 1, form and the second connecting hole of described the first joint pin 21 interference fit and the second joint pin 11 coordinating with described the first connecting hole 22, the part that described the second joint pin 11 extends to described outside through described the first connecting hole 22 forms fusion-welded portion 12.Described the first terminal 3 is injection molding type integrative-structure with described base 2, and described the second terminal 4 is inserted in the jack 23 of described base 2.The push-button switch of the present embodiment is fixedly connected with upper cover 1 and base 2 except the first joint pin 21 is set with the second connecting hole interference fit, also be provided with fusion-welded portion 12, after described fusion-welded portion 12 melting welding, described upper cover 1 further can be fixedly connected with base 2, very reliable by adopting above-mentioned two kinds of fixed connection structures that upper cover 1 is fixedly connected with base 2, described upper cover 1 can delamination after being fixedly connected with base 2, has good result of use.
In the present embodiment, described base 2 inside form for spacing to prevent the positive stop lug boss 24 of described the second terminal 4 bendings to described the second terminal 4; Further, the both sides of described the second terminal 4 form evagination limiting section 41, form the slot 13 that coordinates further to prevent described the second terminal 4 bendings with described evagination limiting section 41 on the inwall of described upper cover 1.By adopting said structure can effectively prevent the second terminal 4 bendings, thereby guarantee that product has good result of use.
As shown in Figure 4, the described base 2 of the present embodiment is outside forms groove 25 with described the first connecting hole 22 correspondence positions, and the axial length of described fusion-welded portion 12 is not more than the axial depth of described groove 25.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
