Further, the first elastic protrusion 213 and the second elastic protrusion 233 are provided with a rib 2331. The arrangement of the reinforcing ribs 2331 improves the connection effect between the terminal plate 2 and the external connection member, and here, the reinforcing ribs 2331 can also improve the overall current resistance and prevent arcing.

Further, the first extension portion 212 and the second extension portion 232 are disposed in a tapered inverted triangle, and the elastic protrusion is located at the lowest position. The first extending portion 212 and the second extending portion 232 are both provided with a limiting hook 235, and the limiting hook 235 abuts against the sidewall of the fixing groove 114. The terminal piece 2 is firmly fixed to the fixing groove 114 by the limiting hook 235, and the anti-falling effect is achieved. Here, the limiting hook 235 is disposed in a barb type, forming a sharp corner, and the limiting hook 235 abuts against the fixing groove 114 to form a fastening effect.

When the terminal plate 2 is fixed in the cavity 11, the first connecting portion 22 and the second connecting portion 24 are respectively fixed on the two fixing bases 111, the first extending portion 212 and the second extending portion 232 extend into the lower portion of the main body 1 through the fixing groove 114, and both the first elastic protrusion 213 and the second elastic protrusion 233 extend into the through hole 14, and form the clamping opening 234. The limiting hook 235 enables the terminal piece 2 to be integrally and firmly fixed with the main body 1. It should be noted here that the first elastic protrusion 213 and the second elastic protrusion 233 do not abut against the bottom end of the through groove 115, so that the whole forms an elastic clamping effect, and when the external connection is inserted, the two elastic protrusions are deformed, so that the elastic protrusions move toward the bottom end of the through groove 115, but the elastic protrusions do not abut against the bottom end of the through groove 115 here, thereby preventing the interference force causing the insertion and the extraction from becoming large. The size of V style of calligraphy groove 121 is greater than the size of V style of calligraphy blade 211, and V style of calligraphy groove 121 and V style of calligraphy blade 211 parallel arrangement, V style of calligraphy groove 121 lie in the outside of V style of calligraphy blade 211.

Compared with the prior art that the puncture is formed only through the single terminal piece 2, in the use process, because the hardness of the conducting part of the conducting wire is too high, the stress generated by the cutting edges is difficult to be reduced, so that the two sides of the cutting edges are not corresponding, the deviation occurs, and the whole puncture effect is influenced. And the arrangement of the first connecting part 22 and the second connecting part 24 improves the overall stability and facilitates the elimination of stress.

The upper cover 3 and the main body 1 are arranged correspondingly, namely, two partition plates 31 are arranged on the upper cover 3, the upper cover 3 is divided into three chambers 32 by the two partition plates 31, each chamber 32 is arranged correspondingly to the cavity 11 of the main body 1, a driving part 321 is arranged in each chamber 32, the driving part 321 is provided with an arc-shaped surface 322 towards one side of the main body 1, and the driving part 321 is positioned at the center of the chamber 32. Here, the driving portion 321 is hollow, and the driving portion 321 extends to the top surface of the upper cover 3. And the hollow-out arrangement is adopted, so that the material cost is saved, and the shrinkage deformation generated in the injection molding process is reduced.

All be equipped with breach 33 on the side around the upper cover 3, breach 33 and wire cooperation, have two breachs 33 around a cavity 32 promptly, two breach 33 and wire cooperation, further, the arcwall face 322 of here drive division 321 is parallel with breach 33, and after upper cover 3 and wire cooperation, have two breach 33 and an arcwall face 322 rather than the laminating promptly, form the drive effect, prevent that the wire is at the motion in-process, and overall motion is unstable.

All be equipped with a plurality of draw-in grooves 34 on the side about upper cover 3, spacing arch 161 stretches into to draw-in groove 34 internal fixation, realizes the cooperation effect. In this embodiment, only three card slots 34 are taken as an example. Three card slots 34 correspond to three different sizes of wires.
