Embodiment

Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however appended accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.

See also Fig. 2 and Fig. 3, it is respectively three-dimensional exploded view of the present utility model and three-dimensional assembled perspective view, and in the present embodiment, the utility model provides a kind of supply socket 1, comprises that an insulator 10, two guide-joining plates 20 and two connect terminal 30, wherein:

Insulator 10 has the external form of a nearly cuboid, and is plastic cement material, and an end face of insulator 10 forms an inserting groove 11 and is provided with a plurality of grooves 12 that run through insulator 10, and inserting groove 11 is connected with groove 12; The other end of insulator 10 is provided with a plurality of holddown grooves 13.

Guide-joining plate 20 is arranged at end face of insulator 10 and corresponding groove 12; The section of connecting 22 that guide-joining plate 20 has a linkage section 21 and extends from linkage section 21, linkage section 21 is provided with a screw 211; Linkage section 21 holds and is arranged in the holddown groove 13, the mutual butt of the inwall of the side of linkage section 21 and holddown groove 13 is so that guide-joining plate 20 is fixed in insulator 10, when assembling, guide-joining plate 20 can not reduce assembling efficiency with connecting terminal 30 rotation synchronously, can effectively save built-up time; In addition, linkage section 21 is vertical mutually with the section of connecting 22, but consider the power supply unit of all size with this supply socket 1 and power transformer etc., its inner space size is neither identical, so linkage section 21 does not then exceed with this form with the relation of the section of connecting 22.

An end that connects terminal 30 holds and is arranged in the inserting groove 11, and the other end forms a screw rod 31 that passes groove 12 and expose to this insulator 10, and screw rod 31 is spirally connected mutually with screw 211, and makes and connect terminal 30 and be fixed on the insulator 10 with guide-joining plate 20; Connect terminal 30 and form a connecting section 32 that offsets with linkage section 21, and the outer rim of connecting section 32 is greater than the outer rim of screw 211; In addition, connect terminal 30 and be cylindric; Moreover, connecting terminal 30 and also have and be socketed on a nut 33 that connects terminal 30 outer rims, nut 33 is for being hexagon, but do not exceed with this form, when its role is to assemble, it is outside and drive and connect terminal 30 rotations that the facility of assembling can directly be socketed on nut 33, so can improve packaging efficiency.

See also Fig. 4 and Fig. 5, be respectively the stereo appearance figure at another visual angle of the utility model and Fig. 4 cutaway view along hatching 5-5, this supply socket 1 is placed in guide-joining plate 20 end of insulator 10 earlier when assembling, and linkage section 21 is held be arranged in the holddown groove 13, at this moment, to connect terminal 30 again holds and is arranged in the inserting groove 11 and passes groove 12, screw rod 31 and screw 211 are spirally connected mutually, be fixed on the insulator 10 with guide-joining plate 20 so that connect terminal 30, and because the outer rim of connecting section 32 greater than the inner edge of screw 211, so connecting section 32 and linkage section 21 mutual butts.

This kind supply socket 1 is to connect terminal 30 and guide-joining plate 20 through after repeating plug for a long time when known supply socket compared to the advantage of known supply socket, the junction that connects terminal 30 and guide-joining plate 20 might produce the phenomenon that gets loose, even fracture, and cause supply socket 1 normally to use; The utility model produces when getting loose connecting terminal 30 and guide-joining plate 20, only needs to rotate to connect terminal 30 that its and guide-joining plate 20 are spirally connected again is fixing, or replaces another group and connect terminal 30 and guide-joining plate 20 and fix again and get final product; The supply socket 1 of whole group need not be changed, so use cost can be saved, material cost, also environmental protection more.
