Abstract

The utility model relates to a production efficiency is high, key board switch who is suitable for automated production, including casing, face lid, from locking plate, interlocking piece, contact - piece set, compression spring, switch compression leg and the compression leg that restores to the throne, be equipped with the shell fragment between locking plate and casing, this shell fragment sets up two elastic arms, and wherein the tip of an elastic arm of the shell fragment tip of pushing down casing another elastic arm is pushed down from the locking plate. The utility model discloses in change the helical compression spring between locking plate and casing among the present key board switch into the adoption shell fragment, its benefit is at the automated production in -process, the production facility only needs can between locking plate and casing direct impress the shell fragment after putting into the casing from the locking plate, if adopt the helical compression spring then be lighter than the length of helical compression spring because of the distance between locking plate and casing, the machine must be earlier with helical compression spring compression when installation helical compression spring, its installation degree of difficulty is big.

Description

It is suitable for the key switch of automated production

Technical field

This utility model relates to a kind of key switch being suitable for automated production.

Background technology

Existing key switch include housing, cover, from locking plate, interlocking sheets would, contact group, helical compression spring, switch compression leg and reset compression leg, its breaker in middle compression leg can arrange two as required or only constitute many gears key switch more, this key switch is because part is different and volume is tiny, can only be by manually by each assembling parts together during assembling, particularly helical compression spring easily causes dislocation when moving between station after installing, it is difficult to automated production, inefficiency.

Summary of the invention

The purpose of this utility model is the problem that the production efficiency in order to solve to exist in existing key switch is low, be difficult to automated production, and provides a kind of key switch being suitable for automated production.

The purpose of this utility model is achieved in that a kind of key switch being suitable for automated production, including housing, cover, from locking plate, interlocking sheets would, contact group, compression spring, switch compression leg and reset compression leg, it is characterized in that described from being provided with shell fragment between locking plate and housing, this shell fragment arranges two elastic arms, and the end of an elastic arm of wherein said shell fragment is pushed down the end of described housing another elastic arm and pushed down described from locking plate. This utility model is existing key switch will change employing shell fragment into from the helical compression spring between locking plate and housing, its benefit is in automated production process, shell fragment only directly need to be pressed between locking plate and housing by production equipment after putting into housing from locking plate, if adopting helical compression spring, because from the length less than helical compression spring of the distance between locking plate and housing, helical compression spring must first be compressed by machine when installing helical compression spring, and its installation difficulty is big.

The described end from locking plate is provided with locating notch and matches with the dop on the elastic arm in described shell fragment.

Two elastic arms in described shell fragment protrude upward.

Two interlocking sheets would it are additionally provided with in described housing.

Described shell fragment is V-arrangement shell fragment, and the elastic force direction of this shell fragment is identical with the direction of motion from locking plate.

Owing to have employed technical scheme described in the utility model, changed into shell fragment between locking plate and housing by the helical compression spring in existing key switch, it is simple to automated production, improve production efficiency.

Detailed description of the invention

See Fig. 1, the described key switch being suitable for automated production, including housing 1, cover 9, from 3, two interlocking sheets would 2 of locking plate, contact group, 4, three switch compression legs 7 of four helical compression springs and reset compression leg 8, with the V-arrangement shell fragment 6 of two elastic arms be placed in housing between locking plate 3 and housing 1, see Fig. 6, this shell fragment arranges two elastic arms 61 and 62, the end of a wherein elastic arm 61 of shell fragment is provided with dop 611, dop 611 is to living the locating notch 31 of self-locking sheet end in Fig. 5, and shell fragment another elastic arm 62 pushes down the inner chamber of housing as shown in Figure 3.

In Fig. 1, contact 5 constitutes contact group with other movable contact spring having been placed in housing; Article four, helical compression spring matches with reset compression leg 8 and three switch compression legs 7 respectively.

As can be seen from Fig. 3, less from the distance between locking plate right part and housing, if using helical compression spring, then in automated production process, helical compression spring first must be compressed to and just can put into less than from the distance between locking plate right-hand member and housing by machine, so producting process difficulty is big; And after adopting the technical solution of the utility model, machine can directly by between right from locking plate for shell fragment press-in and housing, and shell fragment stress is shunk automatically until the dop of shell fragment snaps in positions shell fragment without being shaken in the movement of assembling process in the locating notch of locking plate.
