[0028] like Figure 1-4As shown, the circuit board power supply welding structure for a circuit breaker proposed by the utility model comprises a circuit board 1 and a power supply 2.

[0029] In this embodiment, the welding structure includes a power welding partition bar 3 fixed to the upper surface of the circuit board 1 and a multi-size power positioning mechanism 4 installed at the power welding partition bar 3 for welding and positioning power supplies 2 of various sizes.

[0030] Specifically, refer to Figure 2 The multi-size power source positioning mechanism 4 includes a base ring 41 movably connected to the power source welding partition strip 3, a rotating ring 42 rotatably connected to the base ring 41, a distance adjusting seat 43 fixedly installed on the upper surface of the rotating ring 42, a pair of positioning arms 44 that translate equidistantly in opposite directions along the distance adjusting seat 43, a positioning strip plate 45 connected to the ends of the two positioning arms 44, a welding head insertion strip 46 fixed to one of the positioning strip plates 45, and a height adjustment component 47 for realizing height adjustment of the welding head insertion strip 46.

[0031] In this embodiment, the welding head insertion strip 46 is provided with a strip hole for the welding head to pass through.

[0032] Based on the above, a transverse pitch adjusting screw shaft 431 is rotatably connected inside the pitch adjusting seat 43, one end of each of the two positioning arms 44 is fixedly connected with a transverse threaded collar 444 threadedly engaged with the transverse pitch adjusting screw shaft 431, and a sliding groove for the positioning arm 44 to translate is provided on the upper surface of the pitch adjusting seat 43.

[0033] Furthermore, the two positioning arms 44 are fixedly connected to a first guide shaft 441, and the opposite ends of the two first guide shafts 441 are respectively movably engaged with one end of the first guide shaft cylinder 442, and the outer wall of the first guide shaft cylinder 442 is fixedly connected to the outer wall of the distance adjustment seat 43 through a short shaft. The movably engaged sleeve connection between the first guide shaft 441 and the first guide shaft cylinder 442 provides further guidance for the translation of the two positioning arms 44.

[0034] Furthermore, a column sleeve 451 is fixedly connected to the upper surface of the positioning strip 45, and the column sleeve 451 is movably sleeved with one end of the positioning arm 44. The outer wall of the column sleeve 451 is a square structure and is integrally fixedly sleeved with a baffle 4511. The height adjustment assembly 47 includes a second guide shaft cylinder 471, a second guide shaft 472 movably engaged with both ends of the second guide shaft cylinder 471, a clamping block 473 fixed to the end of the second guide shaft 472 and engaged between the baffle 4511 and the positioning strip 45, and a vertical pitch adjustment screw shaft 474, one end of which is fixedly connected to the second guide shaft cylinder 471 and the other end of which movably passes through the second guide shaft 472, and the first guide shaft cylinder 442 is rotatably connected with a vertical threaded collar 443 threadedly engaged with the vertical pitch adjustment screw shaft 474. When the vertical threaded collar 443 is rotated, the threaded engagement between the vertical threaded collar 443 and the vertical pitch adjustment screw shaft 474 causes the height adjustment assembly 47 to move up and down, thereby driving the positioning strip plate 45 and the welding head insertion strip 46 thereon to move up and down to accommodate welding heads of different lengths passing through the strip holes.

[0035] Based on the above, the outer wall of the base ring 41 is fixedly connected with a handle 411 by bolts, and the lower surface of one end of the handle 411 is in contact with the upper surface of the circuit board 1. By pressing the handle 411, the stability of the base ring 41 can be increased, which facilitates the rotary welding operation.

[0036] The working principle of this embodiment is as follows: the base ring 41 is sleeved on the inner ring of the power source 2. Since the inner ring of the power source 2 is approximately equal to the outer ring of the base ring 41, a seamless sleeve can be achieved. Then the power source 2 to be welded is placed in the position shown in the figure, and the transverse pitch adjustment screw shaft 431 is rotated. The two positioning arms 44 are driven to approach each other through the threaded engagement between the transverse threaded collar 444 and the transverse pitch adjustment screw shaft 431, so that the two positioning strips 45 are simultaneously attached to the outer wall of the power source 2 to position the power source 2 at the center of the power source welding partition strip 3. Then the welding head is passed through the strip hole of the welding head insertion strip 46, and the handle 411 is pressed with one hand to increase the stability of the base ring 41. The welding head is held with one hand and moves in a circle along the outer wall of the power source 2, so that the welding liquid can be poured into the joint of the power source 2 and the circuit board 1 to achieve welding fixation.

[0037] In summary, by designing the traditional marked circular power partition into a protruding power welding partition strip 3 and combining it with the design of a multi-size power positioning mechanism 4, the multi-size power positioning mechanism 4 can be accurately positioned on the power welding partition strip 3 and disassembled after welding through the seamless sleeve of the base ring 41 and the power welding partition strip 3. The adjustable distance design of the two positioning strips 45 can accurately position the power supplies 2 of different sizes. Through the rotating connection between the rotating ring 42 and the base ring 41 and the design of the welding head insertion strip 46, the welding head can be positioned at one place and a circular path can be drawn to quickly weld the power supply 2 on the circuit board 1. Through the movable sleeve between the positioning strip 45 and the positioning arm 44 and the design of the height adjustment component 47, the height of the positioning strip 45 and the welding head insertion strip 46 can be adjusted according to the length of the welding head.

[0038] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
