Description
Technical Field
The utility model relates to binding post especially involves a switch copper aluminium terminal.
Background
The terminal is an accessory product for realizing electrical connection, and is industrially classified into a connector category. With higher and higher industrial automation degree and stricter and more accurate industrial control requirements, the use amount of the wiring terminal gradually increases. With the development of the electronic industry, the use range of the connecting terminal is more and more, and the types of the connecting terminal are more and more.
In the prior art, the switch terminal is a wide panel or has no plate hole, and the installation of a small and micro molded case circuit breaker cannot be met. Or the terminal without the plate hole is installed insecurely, so that the loosening risk exists.
SUMMERY OF THE UTILITY MODEL
The utility model provides a switch copper aluminium terminal, can be very convenient install on small-size, miniature moulded case circuit breaker.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a switch copper aluminium terminal, includes the terminal body, terminal body one end is provided with the installation department, the terminal body other end is provided with receives the deformable cable connecting portion of external force.
Above-mentioned scheme is further, the installation department includes the fixed plate, be provided with the through-hole on the fixed plate. The fixed plate can meet the connection requirement of a small and miniature molded case circuit breaker, and the through hole enables the installation to be more firm.
The scheme is further that one end of the cable connecting part, which is far away from the installation part, is provided with a groove for placing a cable. During the use, put into the recess with the cable, reuse crimping instrument makes the terminal body compress tightly the deformation to reach the purpose of fixed cable, adopt this recess can be suitable for the cable of different specifications.
Above-mentioned scheme is further, the cable connecting portion is cylindricly.
Further, the cable connecting part and the mounting part are welded through friction. The effect of friction welding is adopted: 1. the welding joint has high quality and stability; 2. the dimensional precision and the geometric precision of the weldment are high; 3. during friction welding, the welding allowance of a weldment is small, the assembly requirement of a welding opening is not high, the welding power is small, and electric energy is saved; 4. no spark, arc light, harmful gas, vibration, noise and the like; 5. the friction welding is easy to realize full automation.
According to the scheme, the fixing plate is made of high-purity purple copper. The red copper material can effectively avoid the phenomenon of thermal wear after the installation part is contacted for a long time, and the red copper material has good conductive effect.
The terminal body is made of high-purity aluminum. Good plasticity, convenient compression joint, good conductivity and corrosion resistance.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the copper-aluminum terminal for the switch comprises a terminal body 1, wherein the terminal body 1 is made of high-purity aluminum, and has good plasticity, good conductivity and corrosion resistance. 1 one end of terminal body is provided with fixed plate 2, terminal body 1 with fixed plate 2 adopts friction weld's effect through friction weld: 1. the welding joint has high quality and stability; 2. the dimensional precision and the geometric precision of the weldment are high; 3. during friction welding, the welding allowance of a weldment is small, the assembly requirement of a welding opening is not high, the welding power is small, and electric energy is saved; 4. no spark, arc light, harmful gas, vibration and noise; 5. the friction welding is easy to realize full automation. The fixed plate 2 is provided with a through hole 3 which is used for being fixed with the molded case circuit breaker. Fixed plate 2 adopts the red copper material, the phenomenon of the long-term back thermal wear of avoiding effectively installing the position of red copper material, and the red copper material is electrically conductive effectual.
The cable connecting part is cylindrical, the terminal body is far away from one end of the mounting part and is provided with a groove 4, and the groove 4 is used for placing a cable. The cable is placed in the groove, the terminal body is compressed and deformed by using a crimping tool, and therefore the purpose of fixing the cable is achieved, and the groove can be suitable for cables of different specifications.
The utility model discloses a technical advantage and effect:
1. the circuit breaker can be conveniently installed on small and miniature plastic shell circuit breakers, and is more firm to install;
2. the structure is simple, the installation is convenient and the cost is low due to the through hole;
3. the cable can be suitable for cables with different specifications;
4. and the connecting part between the molded case circuit breaker is made of red copper, so that the phenomenon of thermal wear after the installation part is contacted for a long time can be effectively avoided, and the conductive effect of the red copper is good.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
