Technical Field

[0001] The utility model relates to the technical field of circuit breakers, and more specifically, to a waterproof circuit breaker. Background Art

[0002] A circuit breaker is a switch device that can close, carry and interrupt the current under normal circuit conditions, and can close, carry and interrupt the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances, which are extremely important links in the power distribution process.

[0003] The utility model patent with patent publication number CN220821345U discloses a circuit breaker, including a pole and an upper contact arm and a lower contact arm electrically connected to the pole, wherein the pole includes: an upper outlet seat configured to be electrically connected to the upper contact arm; a connector, one end of which is directly connected to the lower contact arm; an arc extinguishing chamber, the upper end of which is connected to the upper outlet seat, and the lower end of which is connected to the connector. In addition, a hollow portion is provided inside the pole, the connector is exposed to the hollow portion, the lower contact arm of the circuit breaker extends into the pole through an opening provided on the pole and directly contacts the connector, and the hollow portion is in fluid communication with the outside of the pole through the opening, so that the heat generated by the energized parts inside the pole can be easily discharged.

[0004] However, in actual use, although this structure can dissipate heat by setting openings, it reduces the waterproof performance of the circuit breaker.

[0025] As attached Figure 1-7 The waterproof circuit breaker shown includes a connection module 1, on which a switch 8 and a wiring hole 9 connected to the circuit breaker element are provided, a first sealing module 2 is provided at the bottom of the connection module 1, a protection module 3 is provided at the bottom of the first sealing module 2, a second sealing module 4 is provided at the bottom of the protection module 3, and a fixing module 5 is provided at the bottom of the second sealing module 4. A plurality of locking modules 6 are connected between the connection module 1, the protection module 3 and the fixing module 5, and sealing plugs 7 are provided at both ends of each locking module 6.

[0026] During specific implementation, the circuit breaker element is connected and matched with the switch 8 and the wiring hole 9, and then the first sealing module 2 is put on the top of the protection module 3, and the top of the protection module 3 is inserted into the connection module 1 to protect the circuit breaker element, and then the second sealing module 4 is put on the fixing module 5, and then the fixing module 5 is plugged and matched with the bottom end of the protection module 3. Finally, the modules are connected and fixed through multiple locking modules 6 to form a whole, so that the first sealing module 2 and the second sealing module 4 are compressed to produce deformation to seal each connection. At the same time, the two ends of each locking module 6 are sealed by the sealing plug 7 to avoid water immersion at the installation location of the locking module 6. At the same time, the locking modules 6 are all on the inner side of the two sealing modules, thereby avoiding the locking modules 6 from being exposed at the connection of each module, thereby achieving sealing, improving the waterproof effect, and preventing the locking modules 6 from being rusted.

[0027] As attached Figure 3 As shown, the connection module 1 includes a cover plate 101, an outer pressure frame 102, an inner pressure frame 103 and a sealing groove 104. The outer pressure frame 102 is arranged on the outer side of the bottom end of the cover plate 101, and the inner pressure frame 103 is arranged on the inner side of the outer pressure frame 102. A sealing groove 104 is formed between the outer pressure frame 102 and the inner pressure frame 103.

[0028] As attached Figure 4 As shown, the first sealing module 2 and the second sealing module 4 have the same structure and are both made of rubber. The first sealing module 2 includes a sealing sleeve 201 and a pressing edge 202 . The outer side of the bottom end of the sealing sleeve 201 is provided with a pressing edge 202 .

[0029] As attached Figure 5 and Figure 6 As shown, the protection module 3 includes a protection shell 301 , a top frame 302 and a frame groove 303 . The top of the protection shell 301 is provided with a top frame 302 , and the bottom of the protection shell 301 is provided with a frame groove 303 .

[0030] When the connection module 1 is connected to the first sealing module 2 and the protection module 3, the sealing sleeve 201 is put on the top frame 302 so that the pressure edge 202 is on the outside of the top frame 302. Then, when the connection module 1 is sleeved, the sealing groove 104 is put on the sealing sleeve 201, and the outer pressure frame 102 is crimped on the pressure edge 202, so that the connection module 1, the first sealing module 2 and the protection module 3 are connected. When waterproofing, the pressure edge 202 is squeezed and deformed, and the gap between the outer pressure frame 102 and the outside of the top frame 302 is sealed, and the sealing sleeve 201 and the top frame 302 form a three-layer isolation layer for further sealing and isolation, thereby improving the sealing, preventing moisture from entering, and improving the waterproofing effect.

[0031] As attached Figure 7As shown, the fixing module 5 includes a substrate 501, an inner slot 502, an outer slot 503 and a sealing frame 504. The inner slot 502 is opened on the top of the substrate 501, the sealing frame 504 is arranged outside the inner slot 502, and the outer slot 503 is opened outside the sealing frame 504.

[0032] When the protection module 3, the second sealing module 4 and the fixed module 5 are connected, the sealing sleeve 201 in the second sealing module 4 is sleeved on the sealing frame 504, the pressing edge 202 is fitted on the bottom of the outer slot 503, the frame slot 303 is directly sleeved on the sealing sleeve 201, and the outer side of the frame slot 303 is slidably connected to the outer slot 503 to press the pressing edge 202, so that when waterproofing, the pressing edge 202 is deformed to seal the connection gap between the outer slot 503 and the protection shell 301. At the same time, the sealing sleeve 201 and the sealing frame 504 also form three isolation layers for further sealing and isolation, thereby improving the sealing, avoiding moisture intrusion, and improving the waterproof effect.

[0033] As attached Figure 1 As shown, the cover plate 101 and the base plate 501 are both provided with a plurality of screw grooves, and a sealing plug 7 is screwed into each screw groove, wherein the bottom end of the screw groove provided on the cover plate 101 and the protective shell 301 are provided with vertically matching through holes, and the top end of the screw groove provided on the base plate 501 is provided with a screw hole vertically matching the through hole, and the locking module 6 includes a rotary joint and a semi-threaded bolt rod, a semi-threaded bolt rod is welded to the bottom end of the rotary joint, and the rotary joint and the sealing plug 7 are both provided with hexagonal grooves of the same size.

[0034] When installing the locking module 6, the semi-threaded bolt rod is inserted into each through hole and then connected to the screw hole, so that the rotary joint squeezes the cover plate 101. At the same time, the semi-threaded bolt rod pulls the base plate 501 inward, so that the cover plate 101 and the base plate 501 are close to each other, so that each module is close to and squeezed against each other, so that each sealing module is deformed under pressure, and each installation gap is sealed. After the locking module 6 is installed, each screw groove is sealed by the sealing plug 7, so that both ends of the locking module 6 are sealed, thereby preventing the locking module 6 from being exposed and rusted, so as to facilitate subsequent disassembly.
