Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
See also Fig. 1 to shown in Figure 3, a kind of key switch comprises a shell 1, a glue core 2, two metal terminals 3, a button 4, a contact terminal 5, a cover plate 6 and a spring 7, wherein:
Two metal terminals 3, correspondence is installed in the caulking groove 21 respectively; Furthermore, this two metal terminal 3 is equipped with the contact jaw 32 that location division 31 reaches by location division 31 top bendings, so embedding to add in the caulking groove 21, this location division 31 gives the location, corresponding contact jaw 32 is all corresponding to be inserted along this terminal embedding hole 25, make contact jaw 32 be arranged in this and accommodate hole 24, further also be to be located in the slideway 22, so can be for contact terminal 5 butt joints.
Contact terminal 5, it is set on the button 4 and is close proximity to spacing block set 42 lower ends; This contact terminal 5 has the socket part 51 and two butt strips 52 by the outside projection of socket part 51 ora terminalis of hollow hole 511, and described socket part 51 is sleeved on the button 4, and described butt strip 52 is that the contact jaw 32 with two metal terminals 3 forms conductive switchs.
The utility model assembling mode is as follows: the location division 31 of two metal terminals 3 is inlaid in the caulking groove 21 of glue core 2, makes the contact jaw 32 of two metal terminals 3 pass terminal embedding hole 25 and be inserted in the slideway 22; After being enclosed within the socket part 51 of contact terminal 5 on the button 4, again this button 4 is installed on the glue core 2, wherein this button 4 is to insert along accommodating hole 24, then spring 7 is contained in the rear end of button 4, fork-shaped reference column 62 with cover plate 6 is installed in the location hole 26 of glue core 2 at last, make cover plate 6 and glue core 2 form affixed, and spring 7 is installed between button 4 and the cover plate 6, so after on the glue core 2 each member being installed in advance, again whole glue core 2 is inserted in the ccontaining cavity 11 of shell 1, the press-side 41 of button 4 passes through hole 12 and exposes along shell, and hole clipping 14 default on the fixture block 63 of cover plate 6 and the shell engages the location, thereby cover plate 6 and shell are carried out affixed, also mean glue core 2 simultaneously and be installed on metal terminal 3 on the glue core 2, button 4, members such as contact terminal 5 and spring 7 are got up by cover plate 6 encapsulation.
As Fig. 4, be schematic diagram under button 4 normalities; Wherein, during these button 4 initial conditions, the butt strip 51 of described contact terminal 5 is electrically to contact with the contact jaw 32 of two metal terminals 3, is conducting state.As Fig. 5, under button 4 pressed state, the butt strip 51 of described contact terminal 5 glides with button 4, simultaneously spring 7 is pressed down, and the contact jaw 32 of butt strip 51 disengagings this moment two metal terminals 3, thus be off-state.Otherwise after button 4 unclamped, button 4 made button 4 reset to initial condition under spring 7 elastic reactions, and the butt strip 51 that makes contact terminal 5 is with sliding on the button 4, and electrically contacted with the contact jaw 32 of two metal terminals 3, from and be conducting state.
The utility model design focal point is the extra glue core design that increases, after assembling members such as two metal terminals, button, contact terminal and spring in advance by this glue core, again the glue core is packed in the accommodation space of shell, so operating personnel can clear and definite each member installation site, make assembling have convenience more, efficient is improved, and it is very convenient to operate, and helps production and processing.
