Description

Technical Field

[0001] This utility model relates to the field of circuit breaker component welding technology, specifically to a circuit breaker terminal block welding fixture. Background Technology

[0002] like Figure 8 As shown, in a miniature circuit breaker, the terminal block 60 needs to be welded with copper wires 61. Generally, the terminal block 60 is placed in a welding fixture, and then the copper wires 61 are placed in it. The copper wires 61 are clamped so that one end is in contact with the terminal block 60 before welding. In actual operation, it was found that the copper wires 61 are prone to rotation and displacement during the clamping process, resulting in positional deviation at the connection between the copper wires 61 and the terminal block 60, which leads to a decrease in welding accuracy and reliability. In addition, due to excessive clamping impact, the copper wires are easily damaged. Therefore, improvements and optimizations are made to address these issues. Utility Model Content

[0020] like Figure 1-8 As shown, the circuit breaker terminal block welding fixture of this utility model includes a fixture base 1, a copper wire clamping assembly 3 for fixing the copper wire 60 during welding, and a terminal block fixing seat 2 for fixing the terminal block 61 during welding. The copper wire clamping assembly 3 includes a lower receiving block 5, an upper pressing block 6, a clamping drive shaft 8 passing through the fixture base 1 and connected at its upper end to the upper pressing block 6, and a copper wire limiting block 7. The clamping drive shaft 8 drives the upper pressing block 6 downward. The copper wire limiting block 7 is moved to dock with the lower receiving block 5. The copper wire limiting block 7 includes a limiting block arc portion 11 and limiting block mounting portions 12 located at both ends of the limiting block arc portion 11. The limiting block arc portion 11 is provided with a limiting block arc groove 13 and a limiting block trapezoidal groove 14 for positioning the lower part of the copper wire 60. The limiting block arc groove 13 is provided with longitudinally arranged limiting block anti-displacement teeth 15 at intervals. The bottom surface of the limiting block trapezoidal groove 14 is provided with transversely arranged limiting block anti-rotation teeth 16 at intervals. The lower receiving block... The upper pressure block 6 includes a lower support block body 18 and a lower support block clamping part 17 located at the front end of the lower support block body 18. The lower support block clamping part 17 has a lower support block mating groove 19 that mates with the limiting block mounting part 12. The lower support block mating groove 19 has a lower support block positioning groove 20 that mates with the arc portion 11 of the limiting block. The upper pressure block 6 includes an upper pressure block body 23 that mates with the lower support block body 18. The upper pressure block body 23 has an upper pressure block clamping part 24 at its front end. The upper pressure block clamping part 24 is provided with an upper pressure block arc groove 25 that is connected to the upper pressure block arc groove 13 and an upper pressure block trapezoidal groove 26 that is connected to the upper pressure block trapezoidal groove 14. The upper pressure block anti-displacement teeth 15 on the upper pressure block arc groove 13 of the copper wire limiting block 7 play the role of preventing the copper wire 60 from moving laterally. The upper pressure block trapezoidal groove 14 plays the role of initial anti-rotation, and together with the upper pressure block anti-rotation teeth 16, effectively prevents the copper wire 60 from rotating, so that the copper wire 60 is positioned more accurately and the welding is more precise when it is welded to the terminal block.

[0021] The limiting block arc groove 13 is located outside the limiting block trapezoidal groove 14, and the upper pressure block arc groove 25 is located outside the upper pressure block trapezoidal groove 26, which facilitates the placement of the copper wire 60 and makes the transition smoother.

[0022] The copper wire clamping assembly 3 also includes a buffer spring 9. The lower receiving block body 18 is provided with a lower spring receiving groove 28 for installing and positioning the buffer spring 9. The upper pressing block body 23 is provided with an upper spring positioning groove 29 corresponding to the lower spring receiving groove 28 and used for positioning the buffer spring 9 when it is pressed. This can effectively relieve some of the impact force generated when the upper pressing block 6 is pressed down, and effectively reduce the risk of deformation and damage to the copper wire 60 when it is clamped.

[0023] The lower receiving block clamping part 17 is provided with lower receiving block end stops 30 on both sides of the lower receiving block positioning groove 20 to prevent the copper wire limiting block 7 from shifting, thereby improving the stability and reliability of the installation of the copper wire limiting block 7.

[0024] The terminal block mounting base 2 is provided with a mounting base limiting groove 32 for receiving and positioning the terminal block 61 and a mounting base clearance opening 33 connected to the mounting base limiting groove 32 and used to make way for the copper wire 60 during welding, making the welding of the copper wire 60 and the terminal block 61 smoother and more convenient.

[0025] The copper wire limiting block 7 is made of rubber, which is elastic and does not easily cause damage when limiting the copper wire 60, thus reducing maintenance costs.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
