Should, binding post and copper bar are tightened together using bolt.As shown in Figure 1, the plane of binding post 1 and copper bar 2
It is in close contact, so as to realize the transmission of electric current.
The contact surface of binding post and copper bar is compacting plane, is influenceed by processing factors, and its contact surface is not exhausted
To smooth, therefore the situation of only protruding parts contact inevitably occurs after binding post and fixed copper bar contact, connect
Contacting surface product can be greatly reduced, so as to cause contact resistance than larger, cause contact site to generate heat.Especially when by high current just
Serious heat condition occurs, will occur wire harness ablation phenomen when heating temp is more than copper fusing point, influence electric current
Normal transmission, reduces the service life of binding post.Further, since the material of binding post is generally fine copper, its hardness compared with
Low, thickness is usually no more than 3mm, as shown in Figure 2, when bolt 3 thrust increase to a certain extent after, the meeting of binding post 1
Deform and situation about around tilting occur, so also result in contact area reduction, contact resistance increase.
Utility model content
The purpose of this utility model is to provide a kind of binding post, with solve prior art middle connecting terminal and copper bar it
Between contact area it is smaller the problem of；The purpose of this utility model, which is also resided in, provides a kind of wiring group using the binding post
Part.
In order to solve the above-mentioned technical problem, the technical scheme of the utility model middle connecting terminal is：
Having in a kind of binding post, including terminal body, terminal body is used to contact contacting for conduction with corresponding copper bar
Face, the contact surface is the frosting handled by frosted.
Binding post also includes the pressure contact portion for being used to crimp fixation with cable being connected with terminal body.
Bolt penetration hole is offered in terminal body.
The technical scheme of connector assembly is in the utility model：
A kind of connector assembly, including copper bar and binding post, binding post include terminal body, have in terminal body with
The conductive copper bar contact surface of the copper bar contact, the copper bar contact surface is the first frosting handled by frosted.
There is the termination contact face that conduction is contacted with the binding post, the termination contact face is process on the copper bar
Second frosting of frosted processing.
The first concaveconvex structure of male-female engagement is respectively arranged with the copper bar contact surface and termination contact face and second recessed
Male structure, the first frosting is made up of the surface of the first concaveconvex structure, and the second frosting is made up of the surface of the second concaveconvex structure.
First concaveconvex structure and the second concaveconvex structure include the groove that parallel interval is set.
Binding post also includes the pressure contact portion for being used to crimp fixation with cable being connected with terminal body.
Connector assembly also includes offering in bolt, terminal body being provided with bolt penetration hole, copper bar and bolt penetration hole pair
The screwed hole answered.
The material of binding post is fine copper.
The beneficial effects of the utility model are：The copper bar contact surface that conduction is contacted with copper bar in terminal body is through overground
Sand processing, so when binding post is contacted with copper bar to be fixed, it is possible to the contact area between increase and copper bar, so as to reduce
Contact resistance, improves conductive through-current capability, reduces fever phenomenon, improve the service life of binding post.

Fig. 2 is the connection diagram of bolt and binding post and copper bar in the prior art；
Contact schematic diagrames of the Fig. 3 for the binding post in one embodiment of connector assembly in the utility model with copper bar；
Fig. 4 is the schematic diagram of another embodiment of connector assembly in the utility model.
Embodiment
One embodiment of connector assembly is as shown in figure 3, the terminals including copper bar 5 and fine copper material in the utility model
Son 4, binding post 4 includes having the copper bar contact surface that conduction is contacted with copper bar 5 in terminal body, terminal body, and the copper bar connects
Contacting surface is to have the termination contact face that conduction is contacted with binding post 4 on the first frosting handled by frosted, copper bar 5, should
Termination contact face is the second frosting handled by frosted.Connector assembly also includes bolt（Not shown in Fig. 3）, terminal body
On offer bolt penetration hole（Not shown in Fig. 3）, screwed hole corresponding with bolt penetration hole is provided with copper bar 5（Do not show in Fig. 3
Go out）, the also pressure contact portion for being used to crimp fixation with cable including being connected with terminal body of binding post 4（Not shown in Fig. 3）.
Because the contact surface of copper bar and binding post is handled by frosted, so in contact, on the first frosting
Salient point or concave point will be chimeric with the concave point on the second frosting or salient point progress, so as to increase contact area, make to connect
Contacting surface product increases to more than twice of plane contact area, contact resistance is greatly reduced, while also enhancing copper bar and wiring
Adhesion between terminal, hinders the deformation of binding post to a certain extent, improves conductive through-current capability, reduces and connect
The heating of contact portion, extends the service life of contact assembly.Further, since only carrying out frosted processing to contact surface, do not interfere with
The line ball of binding post and inlaying for copper bar, it is ensured that other processes are unaffected.
Another embodiment of connector assembly as shown in figure 4, the difference of the connector assembly and above-described embodiment is,
