Abstract

The utility model relates to a small jogging switch, which is composed of a common terminal, a normally closed terminal, a normally open terminal, a base seat, a fitted upper cover, a button, a movable contact piece and a contact piece resetting piece, wherein, three terminals and the base seat are assembled together in a split mode; three through holes are formed at the fixed positions of the original three terminals on the base seat; three terminals are respectively inserted into the three through holes and are in tight fit shape; three terminals are positioned by fitting the top and the inner side of the upper cover. Thereby, the processing rate of finished products is enhanced; the material consumption is reduced; the production efficiency is enhanced; the production cost is reduced; the maintenance cost can be reduced.

Description

A kind of small-sized sensitive switch

The utility model relates to a kind of small-sized sensitive switch, and is relevant with its combining structure especially.

Usually, small-sized sensitive switch is by common terminal, normally closed terminal, Chang Kaiduan, base, cooperates loam cake, button, active contacting plate and contact chip return unit and forms.Wherein, three terminals are shaped on the base by the injection moulding mode, and its processed finished products rate is low, and the material consumption is big, and production efficiency is also low; And when if three terminals or base are damaged, needing increase maintenance cost with the injection moulding integral replacing.

The purpose of this utility model is to provide a kind of small-sized sensitive switch, its processed finished products rate height, and the material consumption is little, and production efficiency is also high, and maintenance cost is low.

For reaching above-mentioned purpose, solution of the present utility model is: small-sized sensitive switch is still by common terminal, normally closed terminal, Chang Kaiduan, base, cooperates loam cake, button, active contacting plate and contact chip return unit and forms.Wherein, for split fits together, the fixed position of corresponding former three terminals forms three perforation on the base between three terminals and the base, and three terminals insert respectively in three perforation and are the tight fit shape, and three terminals also cooperate the top and the inboard location of loam cake.

Above-mentioned perforation is last big, following little shape, and shape is also presented greatly, following little shape and three terminal correspondences are bored a hole.

Also form the convex clip structure that cooperatively interacts on perforation and the terminal.The convex clip structure is made up of perforation upper groove and terminal epirelief grain.

After adopting said structure, the utility model connects the location because of between three terminals and the base by activity, and the mode of production changes split into by original integrated injection molding and assembles, the processed finished products rate is improved, the material depletion is few, and production efficiency also improves thereupon, has reduced production cost.And, can change the part of corrupted separately when if three terminals or base etc. are damaged, and will the switch integral replacing, reduced maintenance cost.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the utility model three-dimensional exploded view;

Fig. 2 is the utility model assembled sectional view.

See also shown in Fig. 1-2, the utility model still is fixed on the base 4 by common terminal 1, normally closed terminal 2, Chang Kaiduan 3, cooperates loam cake 5, button 6, active contacting plate 7 and contact chip return unit (being spring among the figure) 8 to form.

Wherein, the fixed position of corresponding former three

terminals

1,2,3 forms three and goes up big, little perforation 41 down on the base 4, three

terminals

1,2,3 insert respectively in three perforation 41, and

terminal

1,2,3 correspondence perforation 41 shapes are also presented greatly, following little shape, also form cooperatively interact groove 42 and protruding

grain

11,21,31 on perforation 41 and the

terminal

1,2,3; And common terminal 1, normally closed terminal 2 respectively with loam cake 5 tops contact mutually, Chang Kaiduan 3 and loam cake 5 inboard contacts mutually, thus, three

terminals

1,2,3 can be assembled by split and be positioned on the base 4.

Claims

1, a kind of small-sized sensitive switch, by common terminal, normally closed terminal, Chang Kaiduan, base, cooperate loam cake, button, active contacting plate and contact chip return unit and form, it is characterized in that: fit together for split between three terminals and the base, the fixed position of corresponding former three terminals forms three perforation on the base, three terminals insert respectively in three perforation and are the tight fit shape, and three terminals also cooperate the top of loam cake and inboard to locate.

2, a kind of small-sized sensitive switch as claimed in claim 1 is characterized in that: boring a hole is last big, following little shape, and shape is also presented greatly, following little shape and three terminal correspondences are bored a hole.

3, a kind of small-sized sensitive switch as claimed in claim 1 is characterized in that: also form the convex clip structure that cooperatively interacts on perforation and the terminal.
