Abstract

The utility model relates to a pre-insulated copper-aluminum terminal which comprises a body consisting of an aluminum pipe and a copper head terminal, as well as a seal ring mounted at the tail end of the aluminum pipe and a plastic sheath with a sign covered on the outer surface of the aluminum pipe. The pre-insulated copper-aluminum terminal has the benefits that the design of the pre-insulated structure is adopted, thereby being capable of effectively protecting the conductive part from exposing, reducing the area which is in direct contact with the air and prolonging the service life of the terminal; the design of the seal ring is adopted, thereby being capable of effectively preventing water and foreign bodies from entering, protecting the pressing welding position from being corroded and improving the conductive performance; the sign on the plastic sheath adopts the plastic injection molding way, thereby being clear, durable and convenient to identify; and the sign content includes the length of a conductor for plug-in connection, the model of a used pressing mold and the sequence and the frequency of pressure welding, thereby facilitating the mounting and the operation.

Description

Pre insulated copper aluminium terminal

Technical field

The utility model relates to a kind of terminal jockey that is applicable to rated voltage 1KV and following, circular aluminium core power cable, relates in particular to the transition syndeton of aluminum conductor current-carrying part and copper current-carrying part.

Background technology

In the terminal that electrical lead connects, exist connection between the different conductive material continuing conduct power, and there is following shortcoming in the structure of the conventional crimp type copper aluminium terminal (Fig. 1) that uses:

The first, the aluminum pipe that is used for the continued access aluminium cable does not have insulating sheath, poor safety performance;

The second, copper al wiring terminal ends does not have sealing ring, and water resistance is poor, influences the useful life of terminal, and loss also can increase electric power;

The 3rd, conventional crimp type copper aluminium terminal to connection lead and not explanation of used pressing mold, easily causes and uses or misoperation on body;

Summary of the invention

The utility model technical issues that need to address have provided a kind of pre insulated copper aluminium terminal, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: the body of being made up of aluminum pipe and copperhead terminal; Also comprise: the end at aluminum pipe is settled a sealing ring; Outer surface at aluminum pipe covers the plastic sheath that one deck has sign.

Compared with prior art, the beneficial effects of the utility model are: take the pre insulated structural design, can effectively protect current-carrying part not expose, reduce the area that directly contacts with air, prolongation terminal useful life; Employing sealing ring design, effective waterproof and prevent that foreign matter from entering, protection crimping position is not corroded, the raising electric conductivity; Sign on the plastic sheath adopts the injection moulding mode, and is clear, lasting, be convenient to identification; The sign content comprises: grafting conductor length, use pressing mold model, crimping order and number of times, be convenient to fitting operation.

Fig. 1 is a copper aluminium terminal structural representation in the prior art;

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

Fig. 3 is the utility model axle side schematic diagram.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

By Fig. 2, Fig. 3 as seen: the utility model comprises: the body of being made up of aluminum pipe 1 and copperhead terminal 2; Also comprise: the end at aluminum pipe 1 is settled a sealing ring 3; Outer surface at aluminum pipe 1 covers the plastic sheath 11 that one deck has sign.

When the termination that needs will be fit to the aluminum conductor of scope is connected with line bank, at first lead is prepared by the construction specification requirement,, inserted the length of regulation from guidewire port according to the content that indicates on the plastic wrapper, the pressing mold model that selection is indicated is according to the number of times of crimping order crimping regulation.

Claims

1. pre insulated copper aluminium terminal comprises: the body of being made up of aluminum pipe and copperhead terminal; Also comprise: it is characterized in that: the end at aluminum pipe is settled a sealing ring; Outer surface at aluminum pipe covers the plastic sheath that one deck has sign.
