Abstract
The utility model discloses a copper and aluminum wire connection terminal. The copper and aluminum wire connection terminal comprises an aluminum body, wherein one end of the aluminum body is flat, and the other end of the aluminum body is tubular. The whole outer surface of the aluminum body is provided with a first copper layer, and the inner wall of the tubular end of the aluminum body is provided with a second copper layer. The copper and aluminum wire connection terminal has advantages of good electrically-conductive performance and more reliable utilization.
Description
Technical field
The utility model relates to a kind of copper aluminum connecting terminal.
Background technology
Often need to use the copper aluminum connecting terminal to connect different cable, electric equipment with transition in distribution line.Copper aluminum connecting terminal in the market is all to adopt the modes such as soldering, flash welding or friction welding (FW) to connect the copper sheet layer at the flat end outer surface of aluminum body, but adopt this connected mode little in conjunction with the copper-aluminium transition area, be arranged on the pulling force that bears for a long time wire on electric equipment, easily to copper-aluminium transition face shape deterioration, in use resistance is excessive, temperature rise is too high and easy fracture to cause product.
The utility model content
The purpose of this utility model is to provide a kind of conducting electricity very well and copper aluminum connecting terminal that reliability is high.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of copper aluminum connecting terminal comprises that an end is that flat, the other end are the aluminum body of circular tube shaped; The whole outer surface of described aluminum body is provided with the first bronze medal layer, and the inwall of circular tube shaped one end of described aluminum body is provided with the second bronze medal layer.
Further, flat one end of described aluminum body is provided with connecting hole, and described connecting hole is circular hole.
The advantage that the utlity model has is:
By the first bronze medal layer is set, and be provided with the second bronze medal layer on the inwall of circular tube shaped one end of described aluminum body in the utility model on the whole outer surface of aluminum body, so namely increased the copper-aluminium transition face, resistance reduces, and temperature rise reduces, and conducts electricity very well; Simultaneously due to the employing of said structure, also improved the mechanical strength of product, in use can fracture, so have higher reliability.
Description of drawings
Fig. 1 is a kind of structural representation of copper aluminum connecting terminal in the utility model;
Reference numeral shown in figure: 1-aluminum body, 2-the first bronze medal layer, 3-the second bronze medal layer, 4-connecting hole.
Embodiment
Fig. 1 is a kind of structural representation of copper aluminum connecting terminal in the utility model, has shown a kind of embodiment of the present utility model.
A kind of copper aluminum connecting terminal as shown in Figure 1, comprises that an end is that flat, the other end are the aluminum body 1 of circular tube shaped; The whole outer surface of described aluminum body 1 is provided with the first bronze medal layer 2, and the inwall of circular tube shaped one end of described aluminum body 1 is provided with the second bronze medal layer 3.This copper aluminum connecting terminal in use, aluminum body 1 circular tube shaped one end is connected with wire, its flat one end is connected with external electric equipment.
By the first bronze medal layer 2 is set, and be provided with the second bronze medal layer 3 on the inwall of circular tube shaped one end of described aluminum body 1 in said structure on the whole outer surface of aluminum body 1, so namely increased the copper-aluminium transition face, resistance reduces, and temperature rise reduces, and conducts electricity very well; Simultaneously due to the employing of said structure, also improved the mechanical strength of product, in use can fracture, so have higher reliability.
For the ease of being connected with external electric equipment with the copper aluminum connecting terminal, be provided with connecting hole 4 at flat one end of described aluminum body 1, described connecting hole 4 is circular hole.
Obviously, above-described embodiment of the present utility model is only for the utility model example clearly is described, and is not to be restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
