As a preferred embodiment, the plastic casing has two installation cavities, the top of the installation cavity has described in confession
The opening of metal terminal merging, bottom have the through-hole of conductive pin merging for being electrically connected with the electrical connection module；It is described
Two metal terminals are mounted on two installation cavities respectively, and the terminal plate of two metal terminals is made to be divided into plastic casing
Both sides.
As a preferred embodiment, the insulation for the edge of opening for being higher by the installation cavity is equipped between two installation cavities
Boss.
As a preferred embodiment, the altitude range of the opening of installation cavity is greater than described in the distance from top of the insulation boss
0.2mm and less than 2mm.
As a preferred embodiment, the thickness range of the insulation boss is greater than 1mm and less than 3mm.
As a preferred embodiment, the inside of the insulation boss has the fluting that Open Side Down.
As a preferred embodiment, the depth bounds of the fluting are greater than 0.5mm and less than 5mm.
As a preferred embodiment, the groove width range in the direction being recessed between two installation cavities is greater than 1mm
And less than 3mm.
The beneficial effects of the utility model are：
1st, for metal terminal by the support construction on the inside of stamping equipment punch forming wiring shrapnel, the metal left side is part side
Shape structure, bottom carry punching press convex block with up oblique metal clips, side, and punching press convex block can realize the elastic force to shrapnel
Support causes shrapnel elastic force to fail when preventing shrapnel from being deformed because crossing.
2nd, the projection cube structure of 0.5mm height is carried among plastic casing, the creepage distance between two golden parts can be increased,
Total creepage distance is more than 2.5mm, can meet safety requirement.
3rd, plastic casing bottom is more than the fluting of more than 1mm with width, and the depth of fluting is 3mm or so, can be increased
The creepage distance of two circular hole plug wires.Can local plastic cement shrink problem be reduced with material saving simultaneously.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But a kind of electricity of the utility model
Connection component is not limited to embodiment.
