Description

A kind of modified model points to the structure of switch

Technical field

The utility model relates to the structure that a kind of modified model points to switch, refer to especially a kind of can minification and the sensing switch of ease of assembly.

Background technology

Various electronic product is along with scientific and technological progress, in the function design towards diversification, the combined type direction develops, add that ecommerce is in vogue, it is rapider that world-wide web transmits information, therefore, present every telecommunications product, except personal computer, outside the notebook computer, as mobile phone, home telephones etc. are also towards the design that increases screen, allow the user can on screen, utilize pointer to select multinomial preset function (as online, modification or log database and the convenient inquiry memory telephone numbers etc. of organizing) direction develops more, but, form respectively by a plurality of independent switches for the directionkeys and the execute key of user's operation on the conditional electronic product, cause design to go up attractive in appearance and make difficult awkward situation except taking too much space, and it is also quite complicated on user's operation sequence, so the dealer just develops a kind of sensing control switch module, the switch module that splits can be changed into and be single component, the not only easier operation of minification.

Referring to Fig. 1, be the utility model applicant " pointing to the control switch module " in No. 00238525.2 utility model application case of proposition on June 26th, 2000, it comprises that mainly one has the pedestal of common pin and pin, one has the control unit by wedge and axostylus axostyle, and the lid that can wear for axostylus axostyle, and preparation has a plurality of elastomers between control unit and common pin and pin, press elastic parts according to assigned direction action interlock by wedge by forcing in axostylus axostyle, and make elastic parts crimping one pin, be moved to pre-executing location so as to the cursor of exporting on the directional signal control screen, so constitute one and point to switch.

Yet, this sensing switch includes a plurality of elastomers, produce the elasticity difference because of the difference on making easily, cause and use the difference that goes up sense of touch, and in pedestal, must divide and be equipped with a plurality of elastomers, configuration on its space, this kind sensing switch just can't effectively reduce overall volume, with regard to assembling, must increase step simultaneously, improve production cost, in addition, it directly presses on the metallic elastic body by wedge, through causing the damage of metallic elastic body after repeatedly pressure is ground easily, moreover, it is made up of the compressed tablets that a bulb and four ends thereof extend by wedge, is easy to cause the fracture of compressed tablets in the process of pushing, though can add the reinforcing chip reinforcement, but its structure truly has flaw after all, still must improve.

Technical scheme

Main purpose of the present utility model, be to solve above-mentioned defective, avoid the existence of defective, the utility model comprise one group of mutual assembly and in be provided with the lid and the pedestal of disposal area, in this disposal area, be provided with an elastomer and a control unit, and this control unit includes an axostylus axostyle, by wedge, cushion body and conducting body, so, constitute the sensing switch of a minification and ease of assembly, its purpose is as described below:

One of the utility model purpose: elastomer and configuration conducting body thereon that the utility model utilization is disposed on the common pin provide axostylus axostyle to reach by wedge one response force, formation unitary elasticity structure, reduce assembly and use, reach and dwindle volume of switch, cost-effective purpose.

Two of the utility model purpose: elastomer and configuration conducting body thereon that the utility model utilization is disposed on the common pin provide axostylus axostyle to reach by wedge one response force, formation unitary elasticity structure, reducing assembly uses, and improve assembling flow path of the prior art, reach the purpose of ease of assembly.

Three of the utility model purpose: the utility model is provided with a cushion body between in the conducting body and by wedge, avoid directly contacting the conducting body by wedge, so as to improving the defective that wear metal takes place prior art easily, reach the purpose that increases product quality, increases the service life.
