Abstract

The utility model discloses an easy threading formula binding post has wiring section and cover and is in the sleeve pipe in the wiring section outside, a serial communication port, be provided with threading guide portion on the sheathed tube inner wall. The recess has on the sheathed tube outer wall, the recess with the shape of threading guide part is matchd. The utility model discloses an advantage: during the threading, through the guide of guide part, making the electric wire can all enter into the wiring intersegmental part, can not pushing up the wiring section, the electric wire can not the branching, and the threading targets in place also easilier.

Description

A kind of easily threading type binding post

Technical field

The utility model relates to a kind of connection fixing device, is specifically related to a kind of easily threading type binding post.

Background technology

Binding post is exactly for realizing a kind of accessory product be electrically connected, the industrial category being divided into connector.Along with industrial automatization is more and more higher and Industry Control requires more and more stricter, accurate, the consumption of binding post goes up gradually.Along with the development of electron trade, the scope of application of binding post gets more and more, and kind also gets more and more, binding post for being electrically connected comprises plug wire head and is set in the sleeve pipe on plug wire head, the first end of plug wire is the wiring section being arranged to tubulose, and sleeve pipe is generally made up of elastomeric material and is set in wiring section.

And binding post common is at present when threading, electric wire can withstand wiring section, causes bifurcated not easily inlet wire, wears not in place.

Utility model content

The purpose of this utility model is to make up the deficiencies in the prior art, provides the easy threading type binding post that a kind of threading is easy, can put in place.

In order to reach the purpose of this utility model, technical scheme is as follows:

A kind of easily threading type binding post, there is wiring section and be enclosed within the sleeve pipe outside described wiring section, it is characterized in that, the inwall of described sleeve pipe is provided with threading guide member, when threading, described threading guide member place is used for the internal diameter that the minimum widith of threading is less than or equal to wiring section.

Preferably, described threading guide member is a cross section is the loop configuration of right-angled triangle, described right-angled triangle has short right-angle side and long right-angle side, fit in the end of described short right-angle side and described wiring section, and the length of short right-angle side is identical with the wall thickness of described wiring section, described long right-angle side is fitted on the inwall of sleeve pipe.

Preferably, described threading guide member is the elastomeric element of truncated cone-shaped, and described elastomeric element can shrink along its radial direction, and the bottom of described elastomeric element is fixed on the inwall of sleeve pipe, and top is placed in the inside of sleeve pipe.

Preferably, described threading guide member is a cross section is the structure of isosceles triangle, and the base of described isosceles triangle and the inwall of sleeve pipe are fitted.

Preferably, the outer wall of described sleeve pipe has groove.

Preferably, the form fit of described groove and described threading guide member.

The beneficial effect that the utility model has:

During threading, by the guiding of guide member, enable electric wire all enter into wiring intersegmental part, can not push up wiring section, electric wire can not bifurcated, and threading puts in place and is also more prone to.

Embodiment

Below in conjunction with embodiment, the utility model is further described, but protection range of the present utility model is not only confined to embodiment.

Shown in composition graphs 1, Fig. 2, a kind of easily threading type binding post, have connector lug 1, connector lug has wiring section 11, and the outside of wiring section 11 is arranged with sleeve pipe 2.The inwall of sleeve pipe 2 is provided with threading guide member 21, when threading, threading guide member 21 place is used for the internal diameter that the minimum widith of threading is less than or equal to wiring section 11.

Shown in composition graphs 2, for embodiment 1 of the present utility model, threading guide member 21 is cross sections is the loop configuration of right-angled triangle, right-angled triangle has short right-angle side and long right-angle side, fit in the end of short right-angle side and wiring section 11, and the length of short right-angle side is identical with the wall thickness of wiring section 11, long right-angle side is fitted on the inwall of sleeve pipe 2.The hypotenuse of right-angled triangle plays guiding function, and it is inner that electric wire can slide into wiring section 11 along hypotenuse, and can not withstand the end of wiring section 11.

Shown in composition graphs 3, be embodiment 2 of the present utility model, threading guide member 21 is the elastomeric element of truncated cone-shaped, and elastomeric element can shrink along its radial direction, and the bottom of elastomeric element is fixed on the inwall of sleeve pipe 2, and top is placed in the inside of sleeve pipe 2.During non-threading, threading guide member 21 is in the state of contraction, and when electric wire 3 inserts, due to flexible effect, threading guide member 21 is outwards stretched out, and it is inner that electric wire 3 is inserted into wiring section 11 through whole threading guide member 21.In order to play better effect, preferably, when threading guide member 21 upper end is stretched out completely, its upper end just props up the inwall end of wiring section 11.Or when threading guide member 21 upper end is stretched out completely, upper end is used for the internal diameter that the width at threading place is less than or equal to wiring section 11.

Shown in composition graphs 5, be embodiment 3 of the present utility model, threading guide member 21 is cross sections is the structure of isosceles triangle, and the base of isosceles triangle and the inwall of sleeve pipe 2 are fitted.

In addition, the outer wall of sleeve pipe 2 has groove 22, the form fit of groove 22 and threading guide member 21.Such as, threading guide member 21 is isosceles triangular structure, then groove is also isosceles triangular structure.

Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
