Abstract

The utility model relates to a copper-aluminum connecting terminal which includes a copper head and an aluminum stick; the outer surface of the aluminum stick consists of a big aluminum cylinder and a small aluminum cylinder; the copper head consists of a plane and a small copper cylinder; and a welding line is arranged between the jointed part of the small aluminum cylinder and the small copper cylinder. The copper-aluminum connecting terminal has the beneficial effect of adopting the friction welding structure of the copper head and the aluminum stick, which avoids the equipment or connecting piece of a copper material to be directly contacted with the aluminum material part of the terminal and improves the conductivity of the terminal. The Copper-aluminum connecting terminal has the characteristics of good conductivity, strong galvanic etching resistance, long service life, etc.

Description

Copper al wiring terminal
Technical field
The utility model relates to a kind of transition jockey that is applicable to rated voltage 35KV and following, circular, semicircular sector aluminum steel, power cable and electric equipment copper aluminium, relates in particular to a kind of CAL-B copper al wiring terminal.
Background technology
Terminal in the electrical lead connection, all need itself and equipment or other connector are joined to continue conduct power, and some equipment that need connect or connector belong to two kinds of different materials of copper aluminium, need corresponding transition terminal and connect, the conventional transition copper al wiring terminal (as shown in Figure 1) that uses.There are the following problems for such structure:
First, copper-aluminium transition solder joint 3 is connected on the electric interface of terminal and equipment or connector, in the process of installing, can occur copper material equipment or copper material connector simultaneously with terminal surface on the situation of two kinds of Metal Contact of copper aluminium (contact-making surface of aluminium terminal and copper tip extends on the plane of copper tip among the figure, i.e. " 3 " position of locating, cause contact resistance big, poor electric conductivity.
Second: be 45 ° (seeing the A place among the figure) because aluminium terminal carries out the transition to the inclined-plane of copper tip, cause the electrical-contact area of terminal and equipment or connector to reduce;
The 3rd, what the copper-aluminium transition terminal adopted is copper rod 2 and aluminium bar 1 friction welding, adopts the stamping procedure moulding then; In the process of punching press, can make the solder side fracture or produce slight subtle crackle, reduce electric conductivity; Terminal edge and transition face need additional process to carry out the rounding processing, and round corners effect is not obvious, is prone to point discharge phenomenon, poor safety performance in connection procedure.
Summary of the invention
The utility model technical issues that need to address have provided a kind of copper al wiring 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: copperhead and aluminium bar; The outer surface of described aluminium bar is made up of big aluminium cylinder and little aluminium cylinder; Described copperhead is made up of plane body and little copper coin cylinder; Sealing wire is in the joint of little aluminium cylinder and little copper coin cylinder.
Compared with prior art, the beneficial effects of the utility model are: adopt copperhead and aluminium bar friction welding structure, avoided the equipment of copper material or wiring part directly partly to contact with the aluminium material of terminal, improved the electric conductivity of terminal; The utlity model has and conduct electricity very well, anti-couple corrosion is strong, characteristics such as long service life.
Description of drawings
Fig. 1 is a terminal structure schematic diagram in the prior art;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the vertical view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: copperhead 20 and aluminium bar 10; The outer surface of described aluminium bar 10 is made up of big aluminium cylinder 101 and little aluminium cylinder 102; Described copperhead 20 is made up of plane body 201 and little copper coin cylinder 202; Sealing wire 30 is in the joint of little aluminium cylinder 102 and little copper coin cylinder 202;
The plane body 201 in the described copperhead 20 and the transition junction of little copper coin cylinder 202 are vertical plane B.
What the copperhead in the utility model adopted is the forging and pressing operations, and copperhead and aluminum pipe are by friction welding together.What copperhead used is section bar, by behind the forging forming with the operation of Al pipe butt welding, the transition face of copperhead and edge are fillet, and fillet is obvious, need not additional process, has improved safety in utilization; The profile of striding the copperhead of footpath terminal greatly adopts square structure, when guaranteeing conductive area, and the flexibility that has improved terminal applications.The inner coating conductive paste of aluminum pipe, anti-oxidation, the mouth of pipe seals with serum cap.
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, insert up to the bottom from the aluminum pipe mouth, select the crimping tool crimping that is fit to.The terminal that crimping is good is connected on the binding post of wiring unit or wiring part then.

Claims (1)

1. a copper al wiring terminal comprises: copperhead and aluminium bar; It is characterized in that: the outer surface of described aluminium bar is made up of big aluminium cylinder and little aluminium cylinder; Described copperhead is made up of plane body and little copper coin cylinder; Sealing wire is in the joint of little aluminium cylinder and little copper coin cylinder.
