Abstract

The utility model relates to a kind of novel cable binding post, comprise binding post body (4), it is characterized in that: described binding post body (4) front end is connected with aerial condutor clamping plate (3) by fastening bolt (2), aerial condutor clamping plate (3) form the cell body with intrados with the middle all slightly protruding parts of binding post body (4), between aerial condutor clamping plate (3) and binding post body (4), be connected and form an aerial condutor clip slot (1), described binding post body (4) rear end is provided with the cable core indent (5) of attached cable chip.Being connected of two splicing fittings of traditional device clamp and binding post is fused to novel connecting terminal by the utility model, in effective former construction method, there is contact-making surface insufficient load current, easy loosening, corrosion-prone defect, simplify construction process simultaneously, improved efficiency of construction.

Description

Novel cable binding post

Technical field

The utility model relates to power technology field, is a kind of novel cable binding post concretely.

Background technology

In the last few years, along with the extensive use of power cable, the quantity growth of the tie point of power cable and aerial condutor is swift and violent, in construction, traditional method of attachment is that power cable end is osing, osing front end is a circular hole, at aerial condutor end erection unit wire clamp, in wire clamp flat end processing one perforation, two perforation are pressed together with bolt, form being connected of power cable and aerial condutor.There is following defect in traditional construction method: first, by being connected of osing and device clamp, because osing flat horizontal surface is less, both contacts area are comparatively limited, and contact-making surface insufficient load current causes that contact-making surface is overheated; Secondly, by bolt, both are compressed, the insufficient pressure of face and face, the closed intensity of contact-making surface is affected, and under hyperbaric environment, causes joint face oxidation damage.

Summary of the invention

In order to solve deficiency of the prior art, the utility model provides a kind of novel cable binding post, has simplified construction process simultaneously, has improved efficiency of construction, has solved the problem of contact-making surface insufficient load current.

The utility model solves the technical scheme that its technical problem adopts:

A kind of novel cable binding post, comprise binding post body, described binding post body front end is connected with aerial condutor clamping plate by fastening bolt, in the middle of aerial condutor clamping plate and binding post body, all slightly a projection part forms the cell body with intrados, the length 5-10cm of cell body, between aerial condutor clamping plate and binding post body, be connected and form an aerial condutor clip slot, described binding post body rear end is provided with the cable core indent of attached cable chip.

The beneficial effects of the utility model are: being connected of two splicing fittings of traditional device clamp and binding post is fused to novel connecting terminal by this device, in effective former construction method, there is contact-making surface insufficient load current, easy loosening, corrosion-prone defect, simplify construction process simultaneously, improved efficiency of construction.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is plan structure schematic diagram of the present utility model;

Fig. 2 is side-looking structural representation of the present utility model;

In figure: 1, aerial condutor clip slot, 2, fastening bolt, 3, aerial condutor clamping plate, 4, binding post body, 5, cable core indent.

Embodiment

As shown in Figure 1, 2: a kind of novel cable binding post, comprise binding post body 4, described binding post body 4 front ends are connected with aerial condutor clamping plate 3 by fastening bolt 2, aerial condutor clamping plate 3 form the cell body with intrados with the middle all slightly protruding parts of binding post body 4, the length 5-10cm of cell body, between aerial condutor clamping plate 3 and binding post body 4, be connected and form an aerial condutor clip slot 1, described binding post body 4 rear ends are provided with the cable core indent 5 of attached cable chip.

Binding post body 4 front ends are extended and transformed, be made into can rack hollow wire aerial condutor clip slot 1, aerial condutor clamping plate 3 and binding post body 4 are fixed connection by fastening bolt 2, make this device can increase the contact-making surface of wire and cable connecting terminal, the ampacity of contact-making surface is significantly promoted, meet test requirements document.

Claims

1. a novel cable binding post, comprise binding post body (4), it is characterized in that: described binding post body (4) front end is connected with aerial condutor clamping plate (3) by fastening bolt (2), aerial condutor clamping plate (3) form the cell body with intrados with the middle all slightly protruding parts of binding post body (4), between aerial condutor clamping plate (3) and binding post body (4), be connected and form an aerial condutor clip slot (1), described binding post body (4) rear end is provided with the cable core indent (5) of attached cable chip.
