Description

Binding post

Technical field

The utility model belongs to the termination field, is specifically related to a kind of binding post.

Background technology

As everyone knows, in electric power system, often can relate to being connected of electric equipment and cable, need in this case to use binding post to connect.

Traditional a kind of binding post comprises terminal body, and an end of described terminal body is established terminal block, and the other end is established wire barrel; This binding post in use, terminal block is connected with conductive plate on the electric equipment, the line end of cable is inserted in the tube chamber of wire barrel, with hydraulic tongs wire barrel is flattened fastening cable, because this binding post must come connection cable with special equipment (hydraulic tongs) in use, cost is higher, need certain operation skill, and the easy oxidation of the end of a thread can cause the contact resistance between the end of a thread and binding post to increase, during energising, generation loss heating, the cable that is connected with binding post and the insulating barrier of electric equipment are too high because of the temperature rise of being heated, and easily cause the voltage thermal breakdown, cause security incident.

For this reason, occurred a kind of binding post on the market, comprised terminal body, an end of described terminal body is established terminal block, and the other end is established wire barrel; Form the tapped through hole that at least one is disposed radially on the outer wall of described wire barrel, be provided with supporting line ball bolt at least one described tapped through hole; This binding post in use, terminal block is connected with conductive plate on the electric equipment, the line end of cable is inserted in the tube chamber of described wire barrel, thereby its bottom is pressed on cable on the inwall of tube chamber finish connection by screwing the line ball bolt.The binding post of this kind structure need not be installed by special equipment, with low cost, and easily operation, safe and reliable, eliminated the defective that the traditional wired terminal exists, but above-mentioned binding post also has deficiency: this binding post can reliably connect the larger cable of wire diameter in use, and still relatively poor for the less cable connection reliability of wire diameter.

The utility model content

Technical problem to be solved in the utility model is that in the market binding post connects little wire diameter cable and has the relatively poor problem of reliability.

The technical scheme that realizes the utility model purpose is:

A kind of binding post comprises terminal body, and an end of described terminal body is established terminal block, and the other end is established wire barrel;

Form the tapped through hole that at least one is disposed radially on the outer wall of described wire barrel, be provided with supporting line ball bolt at least one described tapped through hole;

Being inserted with the cross section in the tube chamber of described wire barrel is the linear inserted sheet of circular arc, and the inwall of described inserted sheet forms the trunking that the cable line end is set;

The inner of described line ball bolt can be stretched in the described tube chamber cable is pressed in the described trunking.

In the technique scheme, form location notch on the end face of described wire barrel away from described terminal block one end, form the positioning boss of evagination on the outer wall of described inserted sheet, described positioning boss is arranged in the described location notch.

In the technique scheme, be provided with anti-slop serrations in the described trunking.

In the technique scheme, described line ball bolt is breakable structure, and its neck is provided be used to the neck groove of twisting into two parts.

In the technique scheme, the quantity of described tapped through hole is two, is equipped with described line ball bolt in two described tapped through holes.

The utlity model has positive effect:

(1) binding post in the utility model in use, little wire diameter cable is put into the trunking of inserted sheet, and by at least one line ball bolt cable is pressed in the trunking, can realize that thus little wire diameter cable is connected with the reliable of binding post, rational in infrastructure and have a preferably result of use.

(2) in the utility model, the structure that cooperates by positioning boss and location notch are set, can avoid inserted sheet mobile in the tube chamber of wire barrel, thereby make inserted sheet be in all the time the position relative with the line ball bolt, can larger contact-making surface be arranged with inserted sheet after placing thus the cable of trunking compacted, thereby make it that better electric property be arranged.

(3) the described line ball bolt in the utility model is breakable structure, its neck is provided be used to the neck groove of twisting into two parts, when connection cable, thereby it can be twisted into two parts from the neck groove and guarantee that binding post reliably is connected with cable when the fastening follow-up continuous line ball bolt of screwing that puts in place.

Embodiment

A kind of embodiment to binding post of the present utility model elaborates below in conjunction with Figure of description:

A kind of binding post as shown in Figures 1 to 4, comprises terminal body 1, and an end of described terminal body 1 is established terminal block 2, and the other end is established wire barrel 3; Form the tapped through hole that at least one is disposed radially on the outer wall of described wire barrel 3, be provided with supporting line ball bolt 4 at least one described tapped through hole; Being inserted with the cross section in the tube chamber 31 of described wire barrel 3 is the linear inserted sheet of circular arc 5, and the inwall of described inserted sheet 5 forms the trunking 51 that the cable line end is set; The inner of described line ball bolt 4 can be stretched in the described tube chamber 31 cable is pressed in the described trunking 51.Binding post in the present embodiment in use, little wire diameter cable is put into the trunking 51 of inserted sheet 5, then by at least one line ball bolt 4 cable is pressed in the trunking 51, can realize that thus little wire diameter cable is connected with the reliable of binding post, rational in infrastructure and have a preferably result of use, binding post in the utility model in use, if connect the larger cable of wire diameter, described inserted sheet 5 can be taken out from tube chamber 31, the quantity that described tapped through hole is set in the present embodiment is two, is equipped with described line ball bolt 4 in two described tapped through holes.

Form location notch 32 on the end face of described wire barrel 3 in the present embodiment away from described terminal block 2 one ends, form the positioning boss 52 of evagination on the outer wall of described inserted sheet 5, described positioning boss 52 is arranged in the described location notch 32.The structure that cooperates by positioning boss 52 and location notch 32 are set in the present embodiment, can avoid inserted sheet 5 in the tube chamber 31 interior movements of wire barrel 3, thereby make inserted sheet 5 be in all the time the position relative with line ball bolt 4, so that place the cable of trunking 51 just can be by the 4 reliable crimping of line ball bolt.

In the described trunking 51 in the present embodiment anti-slop serrations 53 is set, can further guarantees binding post and cable connection reliability by anti-slop serrations 53 is set.

Described line ball bolt 4 in the present embodiment is breakable structure, and its neck is provided be used to the neck groove 41 of twisting into two parts, and when connection cable, thereby the fastening follow-up continuous line ball bolt 4 of screwing that puts in place can be twisted into two parts it and guarantees that binding post is connected with cable and connect from neck groove 41.
