[0012] Further preferably, the length of the cuboid plastic piece is less than half of the length of the copper bar terminal.

[0013] The filling tightness of the insert piece and the copper bar terminal can be optimized.

[0014] Advantages:

[0015] 1. The plastic hole size is increased to provide maximum protection for the strength of the mold core.

[0016] 2. The production process is stable, and the mold core does not need to be frequently replaced.

[0017] 3. The mold maintenance cost is reduced, and the product production cost is indirectly reduced.

[0018] 4. After the plastic insert piece is inserted, the amount of glue and the glue pouring time are reduced. At the same time, the amount of glue is less, the glue pouring time is short, and the overall cost is reduced. BRIEF DESCRIPTION OF DRAWINGS
