Embodiment
Please refer to shown in Fig. 1 to Fig. 6, that show the concrete structure of the preferred embodiment of the utility model, include metal nut cap 10, insulating body 20 and multiple conducting terminal 30.
Wherein, this metal nut cap 10 is square, and accordingly, the profile of this insulating body 20 is also square, and this metal nut cap 10 has a cavity 11, and in the present embodiment, this metal nut cap 10 is copper material.
This insulating body 20 is embedded in this cavity 11, this insulating body 20 closely cooperates with metal nut cap 10, the surface of insulating body 20 is concordant with the top end face of metal nut cap 10, the upper and lower surface of this insulating body 20 runs through and is formed with accommodating groove 21, and the lateral surface convex of this insulating body 20 is provided with clamping block 22, clamping block 22 is butted on cavity 11 inwall of metal nut cap 10, closely cooperates to make insulating body 20 and metal nut cap 10; Also produced by insert molding is on insulating body 20 in the plurality of conducting terminal 30 spacing side by side setting, and each conducting terminal 30 all exposes the surface of insulating body 20.In the present embodiment, one lateral margin of this accommodating groove 21 has First terrace 201 and second step face 202, the two ends of each conducting terminal 30 are all exposed on First terrace 201 and second step face 202, specifically, this each conducting terminal 30 is all Z-shaped, it includes the first horizontal part 31 of one-body molded connection, connecting portion 32 and the second horizontal part 33, this first horizontal part 31 and the second horizontal part 33 are exposed on First terrace 201 and second step face 202 respectively, this connecting portion 32 is embedded in insulating body 10, and, this second step face 202 is arranged with multiple groove 203, second horizontal part 33 of each conducting terminal 30 is suspended at the top of groove 203, and this conducting terminal 30 is six, and conducting terminal 30 quantity is not limit.
