Abstract
The utility model relates to an outdoor prefabricated type copper wiring terminal, and belongs to the electric power technical field. The structure of the wiring terminal is that one end of the wiring terminal body is provided with a bolt hole; the middle of the wiring terminal body is a wire plugging groove; the other end of the wiring terminal body is provided with a waterproof cap in one-body mould with the wiring terminal body; the waterproof cap is tightly connected with a cable terminal; an inner diameter of the waterproof cap is matched with a diameter of a cross section of the cable. The wiring terminal is made in one-body mould by employing red copper material, and a tin coating is arranged on the surface. The advantages are that the wiring terminal is simple and novel in structure, good in applicability, and strong in practicality. The wiring terminal can tightly connect cable terminal heads equal to and under 35kV in a high voltage power transmission line, thereby generating permanent waterproof effect.
Description
Technical field
The utility model relates to the power technology field, and particularly a kind of outdoor prefabricated type copper tip is applied to the tight linking of 35kV and following cable terminal in the high-tension electricity transmission line, plays the effect of permanent waterproof.
Background technology
at present, known connector structure is by the metal casting moulding, without bucker, designs.Binding post, with after power transmission cable is connected, must be carried out to corresponding wrapping to power transmission cable and the connecting portion of binding post with corresponding insulating tape and processes.The operation of this field fabrication is very complicated, and specification requirement is high, and manpower consumption is large, and work is dangerous strong.Again because long-time, the high power operation of transmission line, can cause wrapping up power transmission cable and being connected of binding post position aging, affect waterproof effect, cause transmission line to have great potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of outdoor prefabricated type copper tip, can not only effectively solve the problem of original binding post working procedure complexity, and can effectively solve transmission line terminals problem of aging, can reach the purpose of permanent waterproof, and can make the fail safe of ultra-high-tension power transmission line greatly improve.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
Outdoor prefabricated type copper tip, comprise binding post body 1, bolt hole 2, wire insertion groove 3 and bucker cap 4, one end of described binding post body 1 arranges bolt hole 2, middle part is wire insertion groove 3, the integrated bucker cap 4 of the other end setting of binding post body 1 and binding post body 1, described bucker cap 4 closely is connected with cable termination; The internal diameter of described bucker cap 4 matches with cross-section of cable diameter.
Described outdoor prefabricated type copper tip adopts the red copper material one-body molded, and surface arranges tin coating.
The beneficial effects of the utility model are: novel structure, simple, application is good.Can make the tight linking of 35kV and following cable terminal in the high-tension electricity transmission line, play the effect of permanent waterproof.Practical.
The accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, and illustrative example of the present utility model and explanation thereof, for explaining the utility model, do not form improper restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
