On pcb board 10 and close to the side of caulking gum 403.It is installed by installation pcb board in lid 3 on the controller, and in pcb board
Electronic key 9, by key support 402 under the extruding of keycap 401, by caulking gum 403 deformation realize to electronic key 9 into
Row squeezes, and so as to complete the control to electronic key 9, the control to electronic key 9 is realized by setting button component 4, ensures
Electronic key 9 can be individually replaced electronic key 9 when damaging, and effectively reduce the cost of repair, due on pcb board 10
Fourth hole 11 is set, realizes and can be entered in the installation that screw 7 is carried out after being dismantled to keycap 401 by fourth hole 11
Into the fifth hole 12 in screw mounting post 6, the disassembly and installation of screw 7 is facilitated.
It is understood that pcb board 10 is equipped with and active key stent multiple fourth holes 11 correspondingly, through-hole
Weld electronic key in edge.Controller pedestal be equipped with 11 one-to-one screw pole 6 of fourth hole, the in screw pole 6 the 5th
Through-hole 12 and fourth hole 11 are coaxially arranged.
In the present embodiment, when carrying out mounting screw, during mounting screw 7, screw 7 successively from the second through-hole 404, lead to by third
Hole 408, fifth hole 12, which is entered in screw pole 6, realizes that screw 7 and screw pole 6 coordinate controller pedestal 2 fixed to housing 1
On, so as to fulfill the fixation of controller.When electronic key 9 to be opened, keycap 401 is pressed, keycap 401 drives key support
402, key support 402 pushes down caulking gum 403, and caulking gum 403 deforms to be moved down, and caulking gum 403 acts on electronics
On button 9, the opening of electronic key 9 is realized.Pressure is unclamped, key support 402 is extensive under the rebound effect of caulking gum 403
Origin position is arrived again.During knockout screw 7, the tamper tool of keycap 401, screwdriver sequentially passes through the second through-hole 404, and third is led to
Hole 408 and fifth hole 12, realize the dismounting to screw 7.After screw 7 is fixed again, it is only necessary to which the keycap 401 more renewed is i.e.
Can, the screw 7 for static controller is realized, button assembly can be arranged on corresponding to the position on controller pedestal 2, and can
It realizes the dismounting to screw and ensures the leakproofness of controller, ensure the overall beautiful of product to reach.
In the present embodiment, electronic key 9 be mounted between pcb board 10 and caulking gum 403 and with close to caulking gum 403
One end be close to caulking gum 403 and arrange.By by electronic key 9 be mounted between pcb board 10 and caulking gum 403 and with by
One end of nearly caulking gum 403 is close to caulking gum 403 and is arranged, the stroke and electronic key 9 that ensure that button assembly 4 keep one
It causes, improves the use feel of button assembly 4, improve the accuracy controlled electronic key 9, button assembly 4 is avoided to press
Diastema.
In the present embodiment, first through hole 5, the second through-hole 404, third through-hole 408 and fourth hole 11 are coaxially arranged, and the
