Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1-2, the present utility model provides an aluminum-copper connection terminal, comprising a copper connection part 2 and an aluminum connection part 1 having a blind hole 7, wherein the end surfaces of the opposite surfaces of the copper connection part 2 and the aluminum connection part 1 are fixedly connected by welding.
In order to improve the connection strength and the contact area of the copper wiring part 2 and the aluminum wiring part 1, a connecting hole 4 penetrating through the aluminum wiring part 1 is formed in the bottom wall of the blind hole 7, a connecting block 5 which is attached to the inner wall of the blind hole and is not rotatable is arranged in the blind hole 7, a connecting rod 10 capable of sliding and penetrating through the connecting hole 4 is arranged on the connecting block 5, threads are formed in the end part, extending to the outside of the aluminum wiring part 1, of the connecting rod 10, and a threaded hole 3 in matched connection with the threaded end of the connecting rod 10 is formed in the copper wiring part 2. Through making the screw thread end of connecting rod 10 be connected with the screw hole 3 cooperation of copper wiring portion 2 to make aluminium system wiring portion 1 and copper wiring portion 2 fixed connection get up, can make things convenient for aluminium system wiring portion 1 and copper wiring portion 2 direct welding operation, the setting of connecting block 5 and connecting rod 10 can strengthen aluminium system wiring portion 1 and copper wiring portion 2 joint strength simultaneously.
Meanwhile, the connecting blocks 5 and the connecting rods 10 are made of copper, so that the connection strength of the copper wiring part 2 and the aluminum wiring part 1 is increased, the connection contact area of the strong copper wiring part 2 and the aluminum wiring part 1 is increased, and the conductive efficiency of the conductive copper wiring part 2 and the aluminum wiring part 1 is improved.
In this embodiment, the blind hole 7 may be a square hole or a round hole, and when the blind hole 7 is a square hole, the external shape of the connection block 5 needs to be set as a square block in order to prevent the connection block 5 from rotating. When the blind hole 7 is a round hole, a sliding groove is arranged in the blind hole 7, and a sliding block which is slidably arranged in the sliding groove is arranged on the outer side of the connecting block 5, so that the connecting block 5 is ensured not to rotate in the blind hole 7.
In this embodiment, the connecting block 5 and the connecting rod 10 can slide out from the blind hole 7, so that the connecting block 5 and the connecting rod 10 can be replaced and maintained conveniently.
In this embodiment, the connecting rod 10 is provided with a plurality of connecting pieces 8 in an array along the circumferential direction thereof, and the connecting rod 10 and the connecting pieces 8 are integrally formed.
