Abstract

The utility model belongs to the key switch field easily produces to current push shaft of key switch to rock a push shaft of key switch who is difficult for rocking who causes contact failure and provide, including the push shaft body, push shaft body cross section be the rectangle structure, be equipped with the pin at the relative both sides face of push shaft body, all be equipped with the card strip at the vertical both ends of other both sides face, form block portion between the vertical card strip in each side two, be equipped with two bosss on the base that corresponds, boss and this block portion location block of base. The utility model discloses utilize push shaft go up to increase with the base on the block portion of boss block, can not produce after making push shaft install on the base and rock, ensure that the pin on the push shaft is good with the circular telegram part contact on the base, can not produce contact failure's the condition.

Description

A kind of push shaft of key switch

Technical field

This utility model belongs to key switch field, particularly relates to the push shaft of a kind of key switch.

Background technology

Key switch push shaft is movable part in key switch, existing key switch push shaft is located on pedestal by cover plate, this is high to the requirement of cover plate, if the bigger meeting in gap causes push shaft to loosen between cover plate and push shaft, cause loose contact between each energising part in key switch, and owing to cover sheet thickness ratio itself is relatively thin, only one of which contact point between cover plate and push shaft, so long-time use has the phenomenon producing loose contact between the contact on push shaft lower end pin and pedestal unavoidably, have a strong impact on product quality.

Utility model content

The purpose of this utility model is that the push shaft for existing key switch is easily generated the push shaft rocking a kind of key switch not easily rocked causing loose contact and provide.

This utility model is achieved by the following technical solution:

A kind of push shaft of key switch, including push shaft body, described push shaft body cross-section is rectangular configuration, it is provided with pin in the relative two sides of push shaft body, it is equipped with card article at the vertical two ends of other two sides, forming holding section between the card article that each side two is vertical, be provided with two boss on corresponding pedestal, the boss of pedestal engages with location, this holding section.

The range difference between distance and the two sides of push shaft body installation card article between two boss is any value between 0mm-0.2mm.

On push shaft, the stand out of the distance between two card articles on the same side and the boss on pedestal is any value between 0mm-0.2mm.

Described card article and push shaft are formed in one structure.

The beneficial effects of the utility model: this utility model utilizes the holding section that on push shaft, increase engages with the boss on pedestal, make push shaft will not produce after being arranged on pedestal to rock, guarantee that the pin on push shaft is good with the energising feature contacts on pedestal, the situation of loose contact will not be produced.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the attachment structure schematic diagram of this utility model push shaft and pedestal.

Detailed description of the invention

Below in conjunction with embodiment, the utility model is described in further detail.

Embodiment

As depicted in figs. 1 and 2, a kind of push shaft of key switch, including push shaft body 1, described push shaft body 1 cross section is rectangular configuration, it is provided with pin 2 in the relative two sides of push shaft body, it should be noted that be equipped with card article 3 at the vertical two ends of other two sides, between the card article that each side two is vertical, forms holding section, being provided with two boss 5 on corresponding pedestal 4, the boss of pedestal engages with location, this holding section.

It is further noted that the range difference that distance between two boss and push shaft body are installed between the two sides of card article is any value between 0mm-0.2mm.

The stand out of the distance between two card articles further it should be noted that on push shaft on the same side and the boss on pedestal is any value between 0mm-0.2mm.

Further it should be noted that described card article and push shaft are formed in one structure.

Card article is it can also be designed cross section is L-shaped structure, and such boss card article after snapping in card article directly limit the movement of boss horizontal direction, thus realizing both engagings, its effect is more preferably.

Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope, the simple change of those ordinary skill in the art and replacement are all within protection domain of the present utility model.
