The plastic cement cover plate 12 of upper end, shell fragment installation chamber 13 is formed between plastic cement pedestal 11 and plastic cement cover plate 12.
Wherein, plastic cement pedestal 11 is equiped with Positive contact terminal 21, positioned at the right-hand member side of Positive contact terminal 21 and and positive pole
The spaced apart negative contact terminal 22 of contact terminal 21, Positive contact terminal 21, negative contact terminal 22 respectively with plastic cement base
The injection of seat 11 is integral, and Positive contact terminal 21, which includes to protrude from the upper surface of plastic cement pedestal 11 and stretch to shell fragment, installs chamber
Positive contact portion 211 in 13, through plastic cement pedestal 11 and extend to the positive pole pin 212 of 11 outer side of plastic cement pedestal, positive pole
Contact site 211 is structure as a whole with positive pole pin 212；Negative contact terminal 22 include protrude from the upper surface of plastic cement pedestal 11 and
The cathode contact portion 221 that stretches in shell fragment installation chamber 13, through plastic cement pedestal 11 and extend to 11 outer side of plastic cement pedestal
Negative pole pin 222, cathode contact portion 221 is structure as a whole with negative pole pin 222.
Further, the metal clips 3 in horizontal cross arrangement is embedded with shell fragment installation chamber 13, metal clips 3 is opened
Provided with up and down completely through shell fragment through hole 31, the positive contact portion 211 of Positive contact terminal 21 is intercalated in the bullet of metal clips 3
In piece through hole 31, the left end edge part in positive contact portion 211 offers the left side support slot 2111 towards left side opening, positive contact
The right-hand member edge part in portion 211 offers the right side support slot 2112 towards right openings, and the left end edge of shell fragment through hole 31 is embedded in
In the left side support slot 2111 in positive contact portion 211, the right part of metal clips 3 is provided with the elasticity towards lower left bending extension
Pressure section 32, the end of elastic pressure section 32 are embedded in the right side support slot 2112 in positive contact portion 211.
Further, the right part of metal clips 3 is equiped with armature contact 4, and the bottom of armature contact 4 extends to gold
Belong to the lower end side of the right part of shell fragment 3, armature contact 4 is located at the top in cathode contact portion 221；The upper surface of plastic cement cover plate 12 opens up
There is button installing hole 121 that is upwardly opening and being connected with shell fragment installation chamber 13, can be relatively up and down in button installing hole 121
Ground is embedded with active button 5, and the upper end of active button 5 protrudes from the upper surface of plastic cement cover plate 12, the bottom of active button 5
Stretch in shell fragment installation chamber 13 and contacted with metal clips 3.
It need to be explained further, plastic cement pedestal 11 of the invention can realize that assembling connects by snap fit and plastic cement cover plate 12
Connect；Certainly, above-mentioned assembly method is not construed as limiting the invention, i.e., plastic cement pedestal 11 of the invention is gone back with plastic cement cover plate 12
Assembly connection can be realized using other modes, such as be spirally connected.
