[specific embodiment]
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figures 1 to 7, a kind of big stroke and there is the key switch of larger overtravel, including pcb board 1 and be set to
Key switch on pcb board 1, key switch include glue lid 2, handle 3, pedestal 4 and glue core 5.Pedestal 4 and glue lid 2 pass through card
The mode connect connects, and glue lid 2 is equipped with a convex slot 21, and handle 3 is set in convex slot 21 and can be along convex slot 21
Inner wall is up and down.Pedestal 4 is equipped with positioning column 41, and 3 bottom of handle is equipped with the mounting hole 31 cooperated with positioning column 41, positioning column
41 protrude from 4 upper surface of pedestal and protrude into the corresponding mounting hole 31 of handle 3.A spring 6, bullet are equipped between handle 3 and pedestal 4
One end of spring 6 is sheathed on the positioning column 41 of pedestal 4, and the other end of spring 6 is set in mounting hole 31.
Specifically, as shown in Figure 3 and Figure 4, big stroke of the invention and the key switch of larger overtravel passes through elasticity
Hanger 22 is fixed on pcb board 1, and contact terminal 42 and lower terminal 43 can be plugged into the gold being welded on pcb board 1
Belong in clip 10, realizes the connection of circuit.Wherein, it is embedded with glue core 5 in the accommodating cavity 32 of 3 bottom of handle, which passes through pressure
Power spring 51 can move up and down in accommodating cavity 32, i.e. the glue core 5 top that is mounted on contact terminal 42 and lower terminal 43, press
Handle 3, which moves downward, drives glue core 5 to move downwardly together, when moving to certain stroke, the bottom surface of glue core 5 and the contact jaw of lower section
Son 42 contacts, and continues to move downward, since the elastic force of 5 internal pressure spring 51 of glue core is greater than the elastic force of contact terminal 42, contact
Terminal 42 be pressurized moves downward until contact terminal 42 contact and lower terminal 43 contact contact, at this point, contact terminal 42 and
Lower terminal 43 is close to, and the compression spring 51 in glue core 5 is withstood, and glue core 5 cannot continue to move downward.

35, positioning column 41 is equipped with guide hole 46 corresponding with guide post 35, and guide post 35 protrudes into guide hole 46 and along guide hole 46
It is up and down.I.e. 6 one end of spring is set on the positioning column 41 of pedestal 4, and the other end of spring 6 is set in mounting hole 31
On guide post 35, and guide post 35 can extend into the guide hole 46 on positioning column 41, and spring 6 is firmly fixed
Between glue lid 2 and pedestal 4, spring 6 is also not easy sideslip when stretching day.So cannot continue to move downward when glue core 5 is withstood
When, handle 3 still can continue to move downward by spring 6, until spring 6 is compressed to the limit, handle 3 is kept out on pedestal 4, this
When contact terminal 42 still maintain and contact with lower terminal 43.The total stroke of key switch i.e. of the invention is big, contact terminal 42 with
Lower terminal 43 may continue to move downward after contacting, and can be realized big stroke pressing mode, and switching after switch can be with
It presses down.Contact terminal 42 contacts stabilization with lower terminal 43, contact pressure will not be caused to subtract because of the elastic extenuation of contact chip
It is small, and then influence contact stabilization.
Preferably, as shown in fig. 7,3 bottom of handle is equipped with an accommodating cavity 32 that Open Side Down, glue core is equipped in accommodating cavity 32
5, glue core 5 moves up and down in accommodating cavity 32 and in accommodating cavity 32.
Preferably, as shown in figure 5, equipped with compression spring 51,5 upper end opening 52 of glue core and equipped with for placing in glue core 5
The mounting groove 53 of compression spring 51, the top inner wall face of accommodating cavity 32 are equipped with a boss 33, one end of compression spring 51 be set in
On the inner wall of 5 mounting groove 53 of glue core, the other end of compression spring 51 is sheathed on the boss 33 of 32 inner wall of accommodating cavity.
Preferably, it as shown in fig. 7, being respectively equipped with blocking portion 34 on 32 side wall of accommodating cavity, is equipped at 5 upper end opening 52 of glue core

The contact of stopper 34 offsets, and glue core 5 can make glue core 5 that can accommodate by convex block 54 in the blocking portion 34 of accommodating cavity 32
It moves up and down and will not fall off in chamber 32.
Preferably, 2 front and rear sides of glue lid are downwardly extending elastic hanger 22, and elastic 22 lower end of hanger is equipped with a convex block shape
At a hanging platform 221.Pcb board 1 is equipped with plug division 11 corresponding with elastic hanger 22, and the elastic hanger 22 on glue lid 2 can be worn
It crosses to the bottom on pcb board 1, the hanging platform 221 in elastic hanger 22 can tangle the bottom of pcb board 1, make key switch and PCB
Plate 1 is fixed.
Specifically, as shown in Fig. 2, when needing to install key switch;Elastic hanger 22 is inserted into inserting on pcb board 1
Socket part 11, the hanging platform 221 in elastic hanger 22 can be kept out in plug division 11, be capable of fixing glue lid 2 on pcb board 1.When
When needing to take out key switch, by bringing it about deformation by compression elasticity hanger 22, elastic hanger 22 is squeezed draws close inwardly,
Hanging platform 221 in elastic hanger 22 is contacted by rear separate with the plug division 11 on pcb board is squeezed, and takes out key switch.The elasticity is hung
Arm 22 has elasticity, and when plug key switch both will not loosen or fall easily, and key puller can be used, by two hanging platforms 221 to
Key switch is extracted in interior extruding, can be carried out quick dismounting and change to key switch, be improved the efficiency of replacement key switch.
Preferably, as shown in Fig. 2, being additionally provided with elastic slice 44, contact terminal 42 and lower terminal 43 on pedestal 4.Contact terminal 42
And lower terminal 43 is set to the side of pedestal 4 and is located at the lower section of glue core 5, elastic slice 44 be set to the other side of pedestal 4 and with handle 3
End face 36 contacts.Specifically, lower terminal 43 is set to 4 front side one end of pedestal, and contact terminal 42 is set to the 4 front side other end of pedestal and position
Above lower terminal 43, elastic slice 44 be set to the rear side of pedestal 4 and with 3 side face contact of handle.Handle 3, which moves downward, drives glue core 5
It moves downwardly together, when moving to certain stroke, the bottom surface of glue core 5 is contacted with the contact terminal 42 of lower section, and is continued downward
Movement, since the elastic force of 5 internal pressure spring 51 of glue core is greater than the elastic force of contact terminal 42, the compression of contact terminal 42 moves downward straight
The contact of contact and lower terminal 43 to contact terminal 42 contacts, at this point, contact terminal 42 and lower terminal 43 are close to, in glue core 5
Compression spring 51 withstood, glue core 5 cannot continue to move downward.
