Description

Touch-switch

Technical field

The utility model relates to electronic switch fields, more specifically, it relates to a kind of touch-switch.

Background technique

Touch-switch is called microswitch, is a kind of electronic switch, when use, which gently presses switch button, can just make out It closes and connects, switch when unclamping hand and both disconnected, internal structure realizes on-off by the springing of metal clips stress.It touches out The advantage for having small contact resistance lotus, accurate operating force error, multi-size etc. is closed, in electronic equipment and white family Electricity etc. is widely used such as: video and audio product, digital product, remote controler, communication product, household electrical appliance, security protection produce Product etc..Because touch-switch is to the condition of the environment (elastic force/ambient temperature and humidity condition less than 2 times of exerting pressure and electrical Performance) button of large scale equipment and high load capacity all uses conductive rubber or pot son to switch hardware elastic slice directly to replace, for example cures Treat equipment, TV remote controller etc..

The volume of touch-switch generally all designs very small, including pedestal, key and cover board, and key is located at base when installation Between seat and cover board, due to the small volume of key, be located at before pedestal securely assembles in cover board, key is the portion for being easiest to loss Point, very big puzzlement is brought to assembly work, so that the working efficiency of assembly is low.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide one kind during assembly key A kind of touch-switch not easy to lose.

To achieve the above object, the utility model provides following technical solution:

A kind of touch-switch, including pedestal, key and cover board, the pedestal are equipped with point touching chamber, and the point touches intracavitary set There is an elastic slice, the key includes bottom plate and briquetting, and the cover board is equipped with the round mouth worn for briquetting, in the briquetting Equipped with inner groovy, the opening of the inner groovy is arranged towards bottom plate end, there are two the briquetting is extended and set on one end of round mouth The port being connected with inner groovy, the interior baffle for being equipped with rubber material of the port, one end of the baffle extends to inner groovy In, the pushing block of setting rubber material in a circular table shape is inserted in the inner groovy, round table-like pushing block has large end face and small end Face, one end of small end face and are equipped with spacing with the bottom wall of inner groovy close to the bottom wall of inner groovy, and outer surface offsets with baffle Touching is moved by the bottom wall of pushing block towards inner groovy, outside a part of slip to port of the baffle.

The utility model is further arranged to: the baffle is opposite to be equipped with guiding surface with the inconsistent one end of pushing block, The guiding surface is bonded with the outer surface of pushing block, and the other end is equipped with arcwall face.

The utility model is further arranged to: the two sides of the bottom plate are equipped with protruding block, and the two sides of the cover board, which are equipped with, to be supplied The bayonet that protruding block plugs.

By using above-mentioned technical proposal, when assembly, by pushing pushing block, drive baffle towards moving outside port, successively Expand the cross-sectional area of briquetting, key can be effectively prevented and be detached from from cover board, then assembles cover board and key together On the base, assembly efficiency is effectively promoted, prevents key from losing.

Specific embodiment

The utility model touch-switch embodiment is described further referring to figs. 1 to Fig. 4.

A kind of touch-switch, including pedestal 1, key 2 and cover board 3, the pedestal 1 are equipped with point touching chamber 10, the point touching It is equipped with elastic slice 4 in chamber 10, the key 2 includes bottom plate 20 and briquetting 21, and the cover board 3 is equipped with to be worn for briquetting 21 Round mouth 30, the briquetting 21 are equipped with inner groovy 210, and the opening of the inner groovy 210 is arranged towards 20 end of bottom plate, described to press Briquetting 21, which extends, to be set on one end of round mouth 30 there are two the port 211 being connected with inner groovy 210, is equipped in the port 211 One end of the baffle 212 of rubber material, the baffle 212 extends in inner groovy 210, is inserted in the inner groovy 210 and is in The pushing block 213 of round table-like setting rubber material, round table-like pushing block 213 have large end face and small end face, a termination of small end face The bottom wall of nearly inner groovy 210, and it is equipped with spacing with the bottom wall of inner groovy 210, outer surface and baffle 212 are inconsistent, by pushing away The bottom wall of block 213 towards inner groovy 210 moves, outside a part of slip to port 211 of the baffle 212.The baffle 212 It is opposite to be equipped with guiding surface 214, the appearance face paste of the guiding surface 214 and pushing block 213 with the inconsistent one end of pushing block 213 It closes, the other end is equipped with arcwall face 215.

In assembly, first key 2 and cover board 3 are cooperated, the briquetting 21 on key 2 is fed through on cover board 3 after round mouth 30, Can have a cuspidated tool using tweezers, insertion inner groovy 210 and pushing block 213 it is inconsistent after, continue towards the bottom of inner groovy 210 The movement of wall direction, pushes pushing block 213 to be displaced, and pushing block 213 can drive two baffles 212 towards port 211 during displacement Outer sliding, after a part of baffle 212 slides out port 211 so that the cross section of briquetting 21 expands so that briquetting 21 Just it will not be detached from from round mouth 30, realize the assembly of key 2 and cover board 3, finally again assemble cover board 3 and pedestal 1.Cover board 3 with the assembly of key 2, no matter during disassembly or installation, key 2 is all not susceptible to lose, and promotes the use of product Service life.

The two sides of the bottom plate 20 are equipped with protruding block 216, and the two sides of the cover board 3 are equipped with the card plugged for protruding block 216 Mouth 31.After cover board 3 and key 2 assemble, protruding block 216 is fastened in bayonet 31, further increases the dress of key 2 Yu cover board 3 With fastness.
