Abstract

The utility model relates to a lead connecting piece which is a pressing line cap including an insulating bush and a spiral spring. The opening end of the insulating bush is trumpet-shaped; a spiral flute matched with the outer surface of the spiral spring is formed on the inner surface of the insulating bush; and the spiral spring is spirally assembled in the insulating bush. A plurality of protrusions are uniformed distributed on the outer circumference of the insulating bush; the spiral spring takes the shape of a circular truncated cone, and the cone angle direction is opposite to the opening direction of the insulating bush; the protrusions are strip-shaped and arranged in the axial direction of the insulating bush, and the protrusive cross-sections can be in the shape of triangle, rectangle, trapezoid, semicircle or semiellipse. The spiral spring is used for the spiral split joint of the lead, no pressing line pincers are needed during the split joint process, and the implement can be finished only by handwork, so that the practicability of the pressing line cap is greatly improved.

Description

A kind of Wire crimping cap

Technical field

The utility model relates to a kind of wire connector, particularly relates to a kind of Wire crimping cap.

Background technology

Wire crimping cap is to be used for the special-purpose member that some leads splice conducting fast, and existing Wire crimping cap is made up of insulating case and the metal clamp pipe that is inserted in the insulating case.Several strands of electric wires are peelled off to twist behind the insulating barrier insert in the metal clamp pipe of this product together, compress corresponding position with Crimping Pliers again, make the metal clamp pipe distortion in the Wire crimping cap, some leads that are inserted in the Wire crimping cap are promptly firmly spliced conducting.Though existing Wire crimping cap can be used for the quick splicing of lead, must with the supporting use of Crimping Pliers, do not having the very difficult pressing splicing work of manually finishing lead under the situation of Crimping Pliers.

The utility model content

Technical problem to be solved in the utility model be overcome existing Wire crimping cap in the lead splicing must with the supporting use of Crimping Pliers, can't break away from Crimping Pliers and the manual problem of splicing.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of Wire crimping cap, it comprises insulating case and helical spring, the openend of described insulating case is horn-like, the inner surface of insulating case is provided with the helical groove that matches with the helical spring outer surface, and the helical spring spinning is in insulating case.During use, electric wire afterbody crust is peelled off, the electric wire that connect is inserted to tighten simultaneously get final product.

Be laid with several projections on the outer circumference surface of insulating case described in the utility model, can increase frictional force when screwing pressure cap, play anti-skidding effect.

As improvement of the present utility model, helical spring described in the utility model is round table-like, and its cone angle direction is opposite with the opening direction of insulating case; Described projection is a strip, axially is provided with along insulating case, and the cross section of projection can be triangle, rectangle, trapezoidal, semicircle or half elliptic.

The utility model does not use Crimping Pliers because use helical spring splicing lead in the splicing, can finish by hand, has improved the practicality of Wire crimping cap greatly.

Fig. 2 is the left view of Fig. 1;

Fig. 3 is a vertical view of the present utility model;

Fig. 4, Fig. 5, Fig. 6, Fig. 7 are respectively the part sectioned view of the projection on the insulating case.

Embodiment

Below in conjunction with accompanying drawing the utility model is made detailed explanation.

As shown in Figure 1, the utility model comprises insulating case 2 and helical spring 3, and the openend 1 of described insulating case 2 is horn-like, and the inner surface of insulating case 2 is provided with the helical groove that matches with helical spring 3 outer surfaces, and helical spring 3 spinnings are in insulating case 2.

Preferably, be laid with several projections 4 on the outer circumference surface of insulating case 2 described in the utility model, as Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, described projection can be strip, axially be provided with along insulating case 2, the cross section of projection 4 can be triangle, rectangle, trapezoidal, semicircle or half elliptic.

More preferably, helical spring 3 described in the utility model is round table-like, and its cone angle direction is opposite with the opening direction of insulating case 2.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection range of the present utility model.
