Abstract
The utility model discloses a cylindrical pin in a power plug, wherein the cylindrical pin is capable of reducing material consumption so as to decrease material cost. The cylindrical pin comprises a cylindrical pin body equipped with a top-end seal opening and an inner cavity with an opening on the tail end of the cylindrical pin body. A binding post in close fit with the cylindrical pin body is disposed inside the inner cavity. Thus, the tail portion of the cylindrical pin body and the binding post inside the inner cavity of the cylindrical pin body form a wiring portion. The wiring portion is equipped with a penetrating wiring hole and a locking threaded hole communicated with the wiring hole. The cylindrical pin is widely suitable for various plugs and especially various power plugs.
Description
Technical field
The utility model relates to the pin in attaching plug, refers more particularly to the cylindricality pin in a kind of attaching plug.
Background technology
As everyone knows, the cylindricality pin in traditional attaching plug, its structure comprises: solid cylindricality pin body, the afterbody of pin body offers the wiring hole running through and the locking screw pit communicating with this wiring hole.Because the pin body of this cylindricality pin is all solid conventionally, material cost is higher.During use, the wire of drawing of power line is inserted in wiring hole, then, screw is screwed in locking screw pit, the top of screw is held out against the wire incoming end inserting in wiring hole on the hole wall of wiring hole.In tightening the process of screw, loosening in order to prevent from drawing wire incoming end, conventionally to make very large strength, sometimes the wire incoming end because the excessive and damage of exerting oneself even fractures, have influence on the reliability that wire is connected with cylindricality pin, also make wire can not normally pass through rated current.
Utility model content
Technical problem to be solved in the utility model is: thus a kind of cylindricality pin that can reduce in the attaching plug that material consumption reduces material cost is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the cylindricality pin in attaching plug, comprise: cylindricality pin body, pin body is provided with top seal, is opened on the inner chamber of tail end, in the inner chamber of pin body, be provided with the binding post with surface of internal cavity close-fitting, make afterbody and the binding post in pin intracoelomic cavity of pin body form wire connecting portion, in this wire connecting portion, offer the wiring hole running through and the locking screw pit communicating with this wiring hole.
Further technical problem to be solved in the utility model is: a kind of cylindricality pin making in the moderate attaching plug of screw pressure is provided.
For solving above-mentioned further technical problem, the technical solution adopted in the utility model is: described wiring hole faces on the hole wall of locking screw pit and is provided with locking pit.
The surface of described locking pit is the spherical of depression.
Described wiring hole and locking screw pit are perpendicular.
The bottom of described binding post is provided with position-limited edge, and described pin body abuts against on position-limited edge.The external diameter of the diameter of described position-limited edge and pin body is suitable.
The beneficial effects of the utility model are: the utility model consists of hollow pin body and the binding post being arranged in pin body, has reduced the consumption of material, has reduced material cost.In addition, by locking pit is set, screw is held out against wire incoming end in this locking pit, wire incoming end forms bending at locking pit, can effectively prevent that wire incoming end from coming off.Like this, when twisting screw, only wire incoming end need be held out against, without exerting oneself very much, prevent because of the excessive wire incoming end that even fractures that damages of exerting oneself, thereby can guarantee that wire is connected with the reliable of cylindricality pin, guarantee that wire normally passes through rated current.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, cylindricality pin in a kind of attaching plug described in the utility model, comprise: columniform pin body 1, pin body 1 is provided with top seal, is opened on the inner chamber 11 of tail end, in the inner chamber 11 of this pin body 1, be provided with the binding post 2 with the surperficial close-fitting of inner chamber 11, make the binding post 2 in the afterbody of pin body 1 and the inner chamber 11 of pin body 1 form wire connecting portion, in this wire connecting portion, offer the wiring hole and the locking screw pit 22 vertical with this wiring hole and that communicate that run through---shown in Figure 2; Described wiring hole consists of the through hole 20 and a pair of through hole 10 that runs through pin body 1 that are opened on binding post 2; The bottom of described binding post 2 is provided with the suitable position-limited edge 21 of external diameter of its diameter and pin body 1, and the afterbody opening of described pin body 1 abuts against on position-limited edge 21.
As shown in Figure 3 and Figure 4, cylindricality pin in another kind of attaching plug described in the utility model, this pin, on the basis of pin shown in Fig. 1 and Fig. 2, faces at the through hole 20 of binding post 2 on the hole wall of locking screw pit 22 and is provided with the locking pit 201 that its surface is the spherical of depression.
During use, the incoming end of wire is inserted in the wiring hole that a pair of through hole 10 by the through hole 20 on binding post and pin body 1 forms, then, employing is provided with the screw of locking the ballhead that pit 201 matches wire incoming end is held out against in locking pit 201, make wire incoming end form bending at locking pit 201 places, thereby effectively prevented that wire incoming end from coming off, guaranteed that well wire is connected with the reliable of cylindricality pin.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection range of the present utility model.
