Abstract

The utility model discloses a compound tubular type conductor post with steel skeleton, which comprises a connecting terminal (1) in the shape of a slender column and an insulating sleeve (2) sheathed on part of the connecting terminal, wherein at least three convex edges (3) are sequentially arranged from one end of the connecting terminal (1) along an axial direction, a through-hole (4) is arranged between two convex edges (3) along a radial direction. The conductor post provided in the utility model has the advantages of simple wiring operation, saved time and labor, and low wire deformation and breakage liability.

Description

Steel skeleton composite tube type binding post

Technical field:

The utility model relates to the binding post of a kind of cable, electric wire connection usefulness, and concrete is that binding post partly is embedded in the binding post in the insulating case.

Background technology:

Existing cable, electric wires etc. are referred to as the binding post that lead connects usefulness, as shown in Figure 1, form by the binding post (11) of metal material and the insulating case (12) that is enclosed within part binding post outside, its middle connecting terminal (11) is elongate column, one bottom portion of binding post (11) is provided with threaded hole (11) vertically, this hole (13) can be by the screw that is threaded and cooperates with it, be axially arranged with two fins (14) from this end along binding post, radially be provided with through hole (15) along binding post between two fins (14), this radial direction through hole (15) communicates with aforementioned threads hole (13); During use lead is penetrated in the radial direction through hole (15), screw down this cable or electric wire then, make it to be fixed in the radial direction through hole (15), and ensuing part lead is wound in the groove that two fins (14) form until filling up, the binding post (11) that will connect this side of lead at last is embedded in the insulating case (12).

The problem that this kind binding post exists is for lead is anchored in the radial direction through hole; usually all need bigger power tighten the screws; and in the process of the turn of the screw, make and the part lead of contact position, screw top distortion even impaired through regular meeting, this situation certainly will influence the conductive effect of lead.

The utility model content:

It is easy and simple to handle, time saving and energy saving and can not damage the steel skeleton composite tube type binding post of lead that technical problem to be solved in the utility model provides a kind of wiring.

For achieving the above object, technical solution of the present utility model is: this steel skeleton composite tube type binding post comprises the binding post that is elongate column and is enclosed within the insulating case of part binding post outside, set gradually at least three fins vertically from an end of binding post, on the binding post between two fins, be disposed radially through hole.

Fin on described binding post is axial is preferably 3.

Technique effect of the present utility model is: owing to be provided with at least three fins on the binding post of this steel skeleton composite tube type binding post is axial, can form at least two grooves like this, the interior through hole of groove is used for threading, another groove is used for lead and is fastened within it, so the operation that lead is fixedlyed connected with binding post is very simple, and can not produce lead distortion or the impaired power of making in the operating process yet.

As a kind of improvement of the present utility model, the free end end face of binding post middle connecting terminal is set to slick and sly curved surface, promptly round bareheaded shape; After adopting such structure, when binding post was inserted jack, this termination had the effect of guiding, thereby can realize easily and fast, connect accurately.

Description of drawings:

Fig. 1 is the structural representation of wire binding post of the prior art.

Among the figure: threaded hole, 14-fin, the 15-radial direction through hole of 11-binding post, 12-insulating case, 13-binding post bottom

Fig. 2 is a structural representation of the present utility model.

Among the figure: 1-binding post, 2-insulating case, 3-fin, 4-radial direction through hole, 5-groove

The utility model is described in further detail below in conjunction with accompanying drawing.

By shown in Figure 2, steel skeleton composite tube type binding post comprises binding post (1) that is elongate column and the insulating case (2) that is enclosed within part binding post outside, set gradually at least three fins (3) vertically from an end of binding post (1), it is just passable that three fins (3) are set usually, at least two grooves (5) between two fins (3), have just been formed like this, radially have through hole (4) in the groove (5) of binding post, the quantity of radial direction through hole (4) also is at least two; The termination of the other end of binding post (1) is preferably the bareheaded shape of circle.

During use lead being inserted binding post (1) goes up in the radial direction through hole (4) of arbitrary groove (5), ensuing lead closely is wound in another groove (5) then, until filling up this groove (5), to be enclosed within the insulating case (2) through the above-mentioned binding post of handling (1) at last, be preferably and be embedded in the insulating case (2), specifically burying way underground can be cast, or insulating material dissolved earlier, then binding post is put into wherein, both are solidified togather Deng insulating material cooling back, and which kind of adopts bury the key that way is not the application underground certainly.

Claims

1, a kind of steel skeleton composite tube type binding post, comprise binding post (1) that is elongate column and the insulating case (2) that is enclosed within part binding post outside, set gradually at least three fins (3) vertically from an end of binding post (1), on the binding post between two fins (3), be disposed radially through hole (4).

2, according to the described steel skeleton composite tube type of claim 1 binding post, it is characterized in that: the fin (3) on described binding post is axial is preferably 3.

3, according to the described steel skeleton composite tube type of claim 1 binding post, it is characterized in that: the free end of described binding post (1) is the bareheaded shape of circle.
