When the device is operated, a wire with an insulating layer is placed at the opening of a wire stripping conductive groove 31, an upper cover 2 is buckled on a bottom shell 1, a wire pressing lug 21 on the inner side of the upper cover 2 is just aligned to the upper side of the wire and the wire stripping conductive groove 31, in the downward extrusion process, the wire is pressed downwards by the wire pressing lug 21, the bottom surface of the wire is subjected to the upward shearing force action of the thin plate wire stripping conductive groove 31, the insulating layer of the wire is cut by the opening of the opening, the cut insulating layer is cracked towards two sides to expose a wire core wire when the downward pressing is continued, the wire core wire continuously descends to the bottom of the wire stripping conductive groove 31 under the pressure of the wire pressing lug 21, and finally the wire core wire is electrically connected with the opening of the wire. Through the mutual matching of the wire stripping conductive groove 31 and the wire pressing bump 21, the microswitch does not need to be subjected to extra wire stripping, welding and other processes in advance before assembly, but is subjected to a buckling process of the upper cover 2 and the bottom shell 1, and a wire is placed above the wire stripping conductive groove 31, so that the requirements of wire stripping and electric connection can be met simultaneously, and the microswitch is simple in structure and convenient and reliable in assembly operation.
Preferably, the middle of the wire pressing bump 21 is recessed to form a clearance groove 211 corresponding to the wire stripping conductive groove 31, and the wire pressing bumps 21 on two sides of the clearance groove 211 are respectively clamped into two sides of the wire stripping conductive groove 31.
As shown in the attached drawings, since the reed 3 is a thin conductive metal sheet, the notch of the wire stripping conductive groove 31 has a cutting edge shearing function of the sheet opening, and meanwhile, the blank-keeping groove 211 divides the wire-pressing projection 21 into two pieces, when the upper cover 2 is fastened to the bottom case 1, the two wire-pressing projections 21 contact with the wire and press the wire to descend integrally, in the descending process, the bottom surface of the middle part of the wire contacts with the wire stripping conductive groove 31, the insulating layer on the bottom surface of the wire is cut off, and the wire core wire is exposed after being split to both sides, the wire core wire continues to move downwards to the bottom of the wire stripping conductive groove 31 and stops descending, at this time, the wire core wire can be stably electrically connected with the groove side and the groove bottom of the wire stripping conductive groove 31, in this embodiment, the protruding lengths of the two wire-pressing projections 21 can make the wire core wire contact with the bottom of the wire stripping conductive groove 31 and then continuously press down the wire on both sides, so that the wire core wires on both sides are slightly lower than the wire in the wire stripping conductive groove 31, and thus, the two wire cores on the middle of which is stripped of the insulating layer can be stably electrically connected with the wire by the two wire stripping conductive groove 21. Because the clearance grooves 211 are located above the wire stripping conductive grooves 31 and leave free spaces above the wires, the wires are only located on two sides of the wire stripping conductive grooves 31 and are subjected to downward pressure in the whole wire pressing and stripping process, and because the insulating layers of the wires have certain elasticity, after the insulating layers below the wires are sheared, the middle of the shearing opening is subjected to upward jacking force of the wire stripping conductive grooves 31, and the two sides of the shearing opening are subjected to downward pressure of the two wire pressing convex blocks 21, the cut insulating layers can be helped to be further torn to the two sides, so that the wire stripping effect is ensured.

Two side edges of the notch of the V-shaped notch 311 are inclined to the middle by a certain angle, when the wire pressing convex block 21 above is extruded downwards, the inclined two side edges further play a role in cutting the insulated layer wire, so that the wire stripping requirement on the insulated layer wire is easier to realize, and meanwhile, the downward movement of the stripped wire core wire is guided, so that the stripped wire core wire can more accurately enter the longitudinal long groove 312 below.
Preferably, the cross section of the line pressing bump 212 is in a small V shape corresponding to the V-shaped notch 311.
As shown in fig. 4, the small V-shaped wire-pressing bump 212 has better strength, so as to prevent the wire-pressing bump 212 from being broken by the reaction force of the wire, and the gap left on both sides is widened from bottom to top when the small V-shaped profile coincides with the V-shaped notch 311, so that the stripped wire insulation layer is conveniently stacked up in the gaps on both sides.
Preferably, the lead wire groove 11 is formed outside the wire stripping conductive groove 31 of the bottom case 1, and the wire pressing protrusion 21 may be half embedded in the lead wire groove 11.
