Abstract
Disclosed is a copper-aluminum composite binding post, mainly solving the problems that as a cooper layer of a conventional binding post is prone to drop due to being vulnerable to damages, the conventional binding post may be increased in resistance and over high in temperature rise, and may affect the normal operation of the an electric power system during the using process. The copper-aluminum composite binding post is characterized in that one end of an aluminum terminal body (1) is provided with a fixing terminal (2) while the other end is provided with a wiring terminal (3); the upper and lower surfaces of the fixing terminal (2) are provided with multiple heat dissipating slots (4); the interior of the heat dissipating slots (4) and the upper and lower surfaces of the fixing terminal (2) are provided with an optimization layer (5); and the optimization layer (5) is a copper layer. According to the copper-aluminum composite binding post, the structure of the fixing terminal is changed and the heat dissipating slots are arranged additionally so that the heat dissipation area of the fixing terminal is enlarged, the temperature rise is lowered, the cooper layer is protected effectively, and the service life of the binding post is prolonged.
Description
Technical field
The utility model relates to a kind of binding post, is specifically related to the compound binding post of a kind of copper aluminium.
Background technology
In prior art, copper aluminium terminal is the normal a kind of copper-aluminum transition connecting terminal adopting.At present, its structure of copper aluminum connecting terminal is on the market the dull and stereotyped end of aluminum terminals and copper.This binding post is by making through punch forming after copper rod, aluminium bar welding again.
Although this binding post in surface recombination copper layer, but because product is in use subject to pulling force and the shearing of wire for a long time, copper layer is vulnerable to destroy and comes off, and in use resistance increases, temperature rise is too high to cause product, affects the normal operation of electric power system.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of copper aluminium compound binding post, the copper layer that has mainly solved existing binding post is vulnerable to destroy and comes off, and in use resistance increases, temperature rise is too high to cause product, affects the problem of electric power system normal operation.
the technical scheme that the utility model adopts is: the compound binding post of a kind of copper aluminium, comprise aluminum terminal body, one end of described aluminum terminal body is provided with stiff end, the other end is provided with terminals, described stiff end upper and lower surface is provided with some radiating grooves, in described radiating groove, is provided with optimization layer with stiff end upper and lower surface.
described terminals are provided with wiring hole.
described stiff end is tabular, and described stiff end is provided with location hole.
described aluminum terminal body comprises changeover portion, and described changeover portion is connected and fixed end and terminals.
Described changeover portion is solid construction.
Described optimization layer is copper layer.
The beneficial effects of the utility model are: changed the structure of stiff end, be additionally provided with radiating groove, not only increased the area of dissipation of stiff end, reduced temperature rise, simultaneously also effectively protected copper layer, extended mechanism useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cutaway view of the present utility model.
1-aluminum terminal body in figure, 2-stiff end, 21-location hole, 3-terminals, 31-wiring hole, 4-radiating groove, 5-optimization layer, 6-changeover portion.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
as shown in Figure 1 with Figure 2, the compound binding post of a kind of copper aluminium, comprise aluminum terminal body 1, one end of described aluminum terminal body 1 is provided with stiff end 2, the other end is provided with terminals 3, described stiff end 2 upper and lower surfaces are provided with some radiating grooves 4, in described radiating groove 4, are provided with optimization layer 5 with stiff end 2 upper and lower surfaces.
described terminals 3 are provided with wiring hole 31.
described stiff end 2 is tabular, and described stiff end 2 is provided with location hole 21.Tabular one end is connected with external connection electrical apparatus.
described aluminum terminal body 1 comprises changeover portion 6, and described changeover portion 6 is connected and fixed end 2 and terminals 3.Aluminum terminal body 1 adopts aluminum material one-body molded.
Described changeover portion 6 is solid construction.Sound construction, intensity is high.
Described optimization layer 5 is copper layer.
The concrete use of the utility model is as follows: radiating groove 4 has increased the surface area of stiff end, and area of dissipation increases.Effective protection is provided also to the copper layer adhering on it simultaneously, makes copper layer be difficult to wearing and tearing and come off, performance is more stable, longer service life.
The beneficial effect of utility model is: changed the structure of stiff end, be additionally provided with radiating groove, not only increased the area of dissipation of stiff end, reduced temperature rise, simultaneously also effectively protected copper layer, extended mechanism useful life.
