Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] The present utility model provides a Figures 1-4 phase failure protector as shown, which includes a housing assembly, a printed circuit board 102, a first connection mechanism and a second connection mechanism. The housing assembly includes a housing 101 and a base 103. A first fixing mechanism is provided between the housing 101 and the base 103. The printed circuit board 102 is installed at the top of the base 103. A heat dissipation hole is provided on one side of the housing 101, so that the heat generated when the phase failure protector works can be discharged in time. At the same time, the housing 101 uses a flame-retardant material, making the phase failure protector more durable.
[0024] In a preferred embodiment, the first connection mechanism includes a first connection bracket 301. A second fixing mechanism is provided between the first connection bracket 301 and the printed circuit board 102, and a third fixing mechanism is provided between the first connection bracket 301 and the base 103. The second connection mechanism includes a second connection bracket 601. A fourth fixing mechanism is provided between the second connection bracket 601 and the printed circuit board 102, and an electrical connection mechanism is provided at the top end of the second connection bracket 601. Through the settings of the first connection bracket 301 and the second connection bracket 601, the printed circuit board 102 and the electrical connection mechanism inside the open-phase protector are both connected by bolts, thus facilitating the disassembly of the open-phase protector for maintenance and improving the convenience of maintaining the open-phase protector.
[0025] Among them, the first fixing mechanism includes a first screw 201 inserted through the bottom end of the base 103. The top end of the first screw 201 penetrates through the side of the housing 101. A countersunk hole 202 is formed in the side of the housing 101, and a first nut 203 is inserted into the countersunk hole 202. The inner wall of the first nut 203 is threadedly connected to the outer wall of the first screw 201. By tightening the first screw 201 in the first nut 203, the housing 101 can be fixed to the base 103, and the first nut 203 is hidden by the countersunk hole 202, making the open-phase protector more beautiful.
[0026] Among them, the second fixing mechanism includes a second screw 401 inserted through the back of the printed circuit board 102. One end of the second screw 401 penetrates through the front of the first connection bracket 301. A first flat washer 402 is provided on the front of the printed circuit board 102, and the first flat washer 402 is sleeved on the outer wall of the second screw 401. A first spring washer 403 is provided on the front of the first flat washer 402, and the first spring washer 403 is sleeved on the outer wall of the second screw 401. A second nut 404 is provided on the front of the first spring washer 403, and the second nut 404 is threadedly sleeved on the outer wall of the second screw 401. By tightening the second nut 404 on the outer wall of the second screw 401 to press against the first spring washer 403, the first spring washer 403 is deformed, and thus the printed circuit board 102 can be fixed to the first connection bracket 301. Moreover, due to the deformed first spring washer 403, the second nut 404 is not easily loosened on the outer wall of the second screw 401, improving the connection stability between the first connection bracket 301 and the printed circuit board 102.
[0027] Among them, the third fixing mechanism includes a third screw 501 inserted through the bottom end of the base 103. One end of the third screw 501 penetrates through the bottom end of the first connecting bracket 301. A second flat washer 502 is arranged at the top end of the first connecting bracket 301. The second flat washer 502 is sleeved on the outer wall of the third screw 501. A second spring washer 503 is arranged at the top end of the second flat washer 502. The second spring washer 503 is sleeved on the outer wall of the third screw 501. A third nut 504 is arranged at the top end of the second spring washer 503. The third nut 504 is threadedly sleeved on the outer wall of the third screw 501. A slot is opened at the bottom end of the base 103. The third screw 501 is located inside the slot. A type cover 701 is clamped at the opening of the slot. By tightening the third nut 504 on the outer wall of the third screw 501 to press against the second spring washer 503, the second spring washer 503 is deformed, so that the base 103 and the first connecting bracket 301 can be fixed. And due to the deformed second spring washer 503, the third nut 504 is not easily loosened on the outer wall of the third screw 501, thereby improving the connection stability between the first connecting bracket 301 and the base 103. The third screw 501 can be hidden by the type cover 701, and at the same time, dust and water protection are carried out.
[0028] Among them, the fourth fixing mechanism includes a fourth screw 602 inserted through the back of the printed circuit board 102. One end of the second connecting bracket 601 penetrates through the back of the second connecting bracket 601. A third flat washer 603 is arranged at the front of the second connecting bracket 601. The third flat washer 603 is sleeved on the outer wall of the fourth screw 602. A third spring washer 604 is arranged at the front of the third flat washer 603. The third spring washer 604 is sleeved on the outer wall of the fourth screw 602. A fourth nut 605 is arranged at the front of the third spring washer 604. The fourth nut 605 is threadedly sleeved on the outer wall of the fourth screw 602. By tightening the fourth nut 605 on the outer wall of the fourth screw 602 to press against the third spring washer 604, the third spring washer 604 is deformed, so that the base 103 and the second connecting bracket 601 can be fixed. And due to the deformed third spring washer 604, the fourth nut 605 is not easily loosened on the outer wall of the fourth screw 602, thereby improving the connection stability between the printed circuit board 102 and the second connecting bracket 601.
[0029] Among them, the electrical connection mechanism includes a plurality of blank unit sheets 801 and power sheets 802 arranged at the top end of the second connection bracket 601. The blank unit sheets 801 and the power sheets 802 are arranged alternately. A elastic pressing sheet 804 is arranged between the blank unit sheet 801 and the second connection bracket 601. Dust-proof pads 803 are arranged at the bottom ends of the blank unit sheets 801 and the power sheets 802. Connection blocks for wire connection are symmetrically and fixedly connected to the top ends of the power sheets 802. Through the arrangement of the elastic pressing sheet 804, the phenomenon that the second connection bracket 601 causes hard extrusion to the blank unit sheets 801 and the power sheets 802 and damages them is avoided. At the same time, the bottom of the electrical connection mechanism is dust-proofed through the dust-proof pads 803, improving the protection effect on the electrical connection mechanism.
[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
