Abstract
The utility model discloses a kind of copper aluminum connecting terminal, belong to wire connection device structure-design technique field, solve little, the easy problem producing fracture in existing copper aluminum connecting terminal copper-aluminium transition cross section.Comprise aluminium body and copper sheet, described aluminium body one end is tubulose, the other end is flat, one end of described copper sheet is connected with the flat end of aluminium body, it is characterized in that: described aluminium body flat end is provided with first protruding and the first groove, described copper sheet one end is provided with second groove that mate protruding with first and the second projection with the first matching grooves.The utility model copper aluminum connecting terminal adopts protruding and groove design, and can fix aluminium body and copper sheet well, copper-aluminium transition area is large, resistance is little, has higher mechanical strength, even if circuit overload, also can not rupture, thus electric conductivity is superior, works more reliable.
Description
Technical field
The utility model relates to wire connection device structure-design technique field, specifically, particularly relates to a kind of copper aluminum connecting terminal.
Background technology
Binding post uses in a large number in distribution, and the line as electric equipments such as transformer, circuit breaker, isolating switches continues, and what usually adopt is copper aluminum connecting terminal.Right existing copper aluminum connecting terminal is make at the flat part welding copper sheet of aluminum terminal body mostly, copper-aluminium transition cross section is little, be arranged on the pulling force and shearing that electric equipment bear for a long time wire, copper-aluminium transition solder side is formed and destroys, in use resistance is excessive, temperature rise is too high to cause product, and easily produce phenomenon of rupture, affect the normal operation of electric power system.
Summary of the invention
The utility model discloses a kind of copper aluminum connecting terminal, for solving little, the easy problem producing fracture in existing copper aluminum connecting terminal copper-aluminium transition cross section, providing that a kind of electric conductivity is superior, the copper aluminum connecting terminal of reliable operation.
The utility model is achieved through the following technical solutions:
A kind of copper aluminum connecting terminal, comprise aluminium body 1 and copper sheet 2, described aluminium body 1 one end is tubulose, the other end is flat, one end of described copper sheet 2 is connected with the flat end of aluminium body 1, it is characterized in that: described aluminium body 1 flat end is provided with the first protruding 3 and first groove 6, described copper sheet 2 one end is provided with and the first protruding 3 the second groove 4 mated and second projection 5 of mating with the first groove 6.
Compared with prior art, the beneficial effects of the utility model are:
The utility model copper aluminum connecting terminal adopts protruding and groove design, and can fix aluminium body and copper sheet well, copper-aluminium transition area is large, resistance is little, has higher mechanical strength, even if circuit overload, also can not rupture, thus electric conductivity is superior, works more reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model copper aluminum connecting terminal;
Fig. 2 is the exploded view of the utility model copper aluminum connecting terminal.
In Fig. 1: 1, aluminium body; 2, copper sheet;
In Fig. 2: 3, first is protruding; 4, the second groove; 5, second is protruding; 6, the first groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of copper aluminum connecting terminal, comprise aluminium body 1 and copper sheet 2, described aluminium body 1 one end is tubulose, the other end is flat, one end of described copper sheet 2 is connected with the flat end of aluminium body 1, it is characterized in that: described aluminium body 1 flat end is provided with the first protruding 3 and first groove 6, described copper sheet 2 one end is provided with and the first protruding 3 the second groove 4 mated and second projection 5 of mating with the first groove 6.
As depicted in figs. 1 and 2, a kind of copper aluminum connecting terminal, comprise aluminium body 1 and copper sheet 2, aluminium body 1 one end is tubulose, the other end is flat, one end of copper sheet 2 is connected with the flat end of aluminium body 1, aluminium body 1 flat end is provided with the first protruding 3 and first groove 6, copper sheet 2 one end is provided with and the first protruding 3 the second groove 4 mated and second projection 5 of mating with the first groove 6, aluminium body 1 and copper sheet 2 adopt solder technology to be connected for overall, embed in the second groove 4 by first protruding 3, second protruding 5 embed the first groove 6 simultaneously, solder technology is adopted to connect aluminium body 1 and copper sheet 2, aluminium body 1 and copper sheet 2 arrange projection and add copper-aluminium transition area with groove, also strengthen the bonding strength of aluminium body 1 and copper sheet 2 simultaneously, the utility model copper aluminum connecting terminal adopts protruding and groove design, aluminium body and copper sheet can be fixed well, copper-aluminium transition area is large, resistance is little, there is higher mechanical strength, even if circuit overload, also can not rupture, thus electric conductivity is superior, work more reliable.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
