Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and more specifically, to a monitoring-type water immersion-proof circuit breaker. Background Technology

[0002] A circuit breaker is a switching device used to connect, carry, and disconnect current in a circuit under normal circuit conditions, and to connect, carry, and disconnect current for a certain time under specified abnormal circuit conditions. Water-resistant circuit breakers use special waterproof materials and structural designs to ensure normal operation in water-immersed environments, effectively preventing electrical faults caused by moisture or water immersion.

[0003] In the wiring process of a circuit breaker, the wire terminals must be precisely inserted into the circuit breaker's wiring holes. Then, by rotating the fastening bolt, the end of the bolt penetrates the terminal, applying pressure to ensure a tight fit between the terminal and the circuit breaker's terminals, guaranteeing a secure electrical connection. However, the lack of a sealing element between the terminals and the wire terminals exposes the connection to the outside air, making both the terminals and wire terminals susceptible to oxidation. Utility Model Content

[0004] Based on the aforementioned technical problem that the connection between the terminal block and the wire terminal block is not equipped with a sealing element, resulting in the connection being exposed to the outside air and easily leading to oxidation of the terminal block and the wire terminal block, this utility model proposes a monitoring-type water immersion anti-electric shock circuit breaker.

[0005] This utility model proposes a monitoring-type water immersion-proof circuit breaker, comprising a circuit breaker, a sealing element, and a sealing ring.

[0006] The circuit breaker includes a mounting base, the outer wall of which has a wiring hole, and both sides of the inner wall of the wiring hole have limit holes.

[0007] The seal is installed inside the mounting base;

[0008] The sealing element includes an insulating plate, the circumferential wall of which protrudes outward to form two extensions, the ends of which extend into the limiting hole, a through hole is provided on the outer wall of the insulating plate, and an embedding groove is provided on both sides of the insulating plate.

[0009] The sealing ring is fitted inside the groove.

[0010] Preferably, the circuit breaker further includes a wiring terminal, which is fixedly installed in a wiring hole.

[0011] Preferably, the outer wall of the terminal block is provided with a first pressure groove, which is in contact with the sealing ring.

[0012] Preferably, the circuit breaker further includes a mounting cover, which is detachably mounted on a mounting base.

[0013] Preferably, the inner wall of the wiring hole is provided with a second threaded hole, and the inner wall of the mounting cover is provided with a fastener, the fastener including a fastening bolt, the end of the fastening bolt passing through the wiring terminal and threadedly connected to the second threaded hole.

[0014] Preferably, the fastening bolt nut end has a second pressure groove, which is in pressure contact with the sealing ring.

[0015] Preferably, the outer wall of the extension is provided with a sliding hole, and an elastic component is installed in the mounting base. The elastic component includes a sliding rod, which is installed in a limiting hole. The end of the sliding rod passes through the limiting hole and is slidably connected thereto. A spring is sleeved on the outer wall of the sliding rod, with one end of the spring abutting against the extension and the other end of the spring abutting against the mounting base.

[0016] Preferably, the outer wall of the extension is provided with a sliding hole, an elastic component is installed in the mounting base, the elastic component further includes an external thread head, the external thread head is rotatably connected to the end of the slide rod, the end face of the external thread head is provided with a cross groove, the inner wall of the limiting hole is provided with a first threaded hole, and the external thread head is threadedly connected to the inner wall of the first threaded hole.

[0017] Preferably, the outer wall of the extension is provided with a sliding hole, the mounting base is provided with an elastic limiting hole, the inner wall of the limiting hole is provided with a support hole, and the end of the sliding rod is inserted into the support hole.

[0018] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0019] 1. By rotating the fastening bolt and moving it spirally into the second threaded hole, the fastening bolt presses the insulating plate inward. The sealing ring on the side of the insulating plate near the terminal presses the connecting piece. The sealing ring is pressed into the first pressure groove. The second pressure groove on the fastening bolt presses the sealing ring on the other side of the insulating plate, thereby sealing the connection between the connecting piece and the terminal and preventing oxidation of the terminal and the wire connection.

[0020] 2. By installing the elastic component, the slide bar can limit the insulation plate. When the power cord is disconnected, the spring can press the insulation plate in the opposite direction, so that the insulation plate is freed from the pressure on the wire terminal, realizing automatic separation and making it easy to pull out the wire. At the same time, the spring's pressure on the insulation plate can position the insulation plate, so that the insulation plate and the terminal are kept at a sufficient distance, which makes it easy for the operator to accurately insert the wire terminal connector into the wiring hole, facilitating quick installation.

[0021] 3. By inserting a screwdriver into the cross groove on the external thread head and rotating the external thread head, the external thread head can be unscrewed from the first threaded hole, which facilitates the installation and disassembly of the elastic component and the assembly of the structure during the production process.

[0036] like Figures 1-7 As shown, a monitoring-type immersion-proof circuit breaker includes a circuit breaker 100, a seal 120, and a sealing ring 140. The circuit breaker 100 includes a mounting base 101, with a wiring hole 103 on the outer wall of the mounting base 101 and limit holes 104 on both sides of the inner wall of the wiring hole 103. The seal 120 is installed inside the mounting base 101.

[0037] The sealing element 120 includes an insulating plate 121. The circumferential wall of the insulating plate 121 protrudes outward to form two extensions 124. The ends of the extensions 124 extend into the limiting hole 104. A through hole 123 is provided on the outer wall of the insulating plate 121. An embedding groove 122 is provided on both sides of the insulating plate 121.

[0038] The sealing ring 140 is fitted into the groove 122.

[0039] The circuit breaker 100 also includes a terminal block 108, which is fixedly installed in the wiring hole 103;

[0040] The outer wall of the terminal block 108 is provided with a first pressing groove 109. The first pressing groove 109 is in contact with the sealing ring 140 by compression. The first pressing groove 109 can limit the sealing ring 140. The sealing ring 140 has insulation properties.

[0041] The circuit breaker 100 also includes a mounting cover 102, which is detachably mounted on the mounting base 101.

[0042] The inner wall of the wiring hole 103 is provided with a second threaded hole 107, and the inner wall of the mounting cover 102 is provided with a fastener 110. The fastener 110 includes a fastening bolt 111. The end of the fastening bolt 111 passes through the wiring terminal 108 and is threadedly connected to the second threaded hole 107. The threaded end of the fastening bolt 111 is screwed into the second threaded hole 107 to fix the wire wiring terminal.

[0043] The nut end of the fastening bolt 111 has a second pressure groove 112, which is in contact with the sealing ring 140. The sealing ring 140 is positioned and pressed by the second pressure groove 112, which improves the stability of the installation of the sealing ring 140. The sealing ring 140, located between the insulating plate 121 and the nut of the fastening bolt 111, can provide moisture protection for the thread end of the fastening bolt 111.

[0044] An extension 124 has a sliding hole 125 on its outer wall. An elastic component 130 is installed in the mounting base 101. The elastic component 130 includes a sliding rod 131, which is installed in a limiting hole 104. The end of the sliding rod 131 passes through the limiting hole 104 and is slidably connected thereto. A spring 132 is sleeved on the outer wall of the sliding rod 131. One end of the spring 132 abuts against the extension 124, and the other end of the spring 132 abuts against the mounting base 101. By installing the elastic component 130, the sliding rod 131 can move the insulating board. When the power cord is disconnected, the spring 132 can press the insulating plate 121 in the opposite direction, so that the insulating plate 121 is freed from the pressure on the wire terminal, realizing automatic separation and making it easy to pull out the wire. At the same time, the pressure of the spring 132 on the insulating plate 121 can position the insulating plate 121, so that the insulating plate 121 and the terminal 108 are kept at a sufficient distance, which makes it easy for the operator to accurately insert the wire terminal connector into the wiring hole 103, facilitating quick installation.

[0045] The extension 124 has a sliding hole 125 on its outer wall. An elastic component is installed in the mounting base 101. The elastic component 130 also includes an external thread head 133. The external thread head 133 is rotatably connected to the end of the slide rod 131. The end face of the external thread head 133 has a cross groove 134. The inner wall of the limiting hole 104 has a first threaded hole 106. The external thread head 133 is threadedly connected to the inner wall of the first threaded hole 106.

[0046] The outer wall of the extension 124 is provided with a sliding hole 125, the inner wall of the mounting base 101 is provided with a support hole 105, and the end of the slide rod 131 is inserted into the support hole 105.

[0047] Working principle: Insert the wire terminal connector into the wiring hole 103. The connector is located between the seal 120 and the terminal 108.

[0048] By pressing a screwdriver against the end of the fastening bolt 111 and squeezing it into the mounting base 101, the end of the fastening bolt 111 passes through the through hole 123, the connecting piece and the terminal 108 on the insulating plate 121 until the end of the fastening bolt 111 abuts in the second threaded hole 107.

[0049] By rotating the fastening bolt 111 and moving it spirally into the second threaded hole 107, the fastening bolt 111 presses the insulating plate 121 inward. The sealing ring 140 on the side of the insulating plate 121 near the terminal 108 presses the connecting piece. The sealing ring 140 is pressed into the first pressure groove 109. The second pressure groove 112 on the fastening bolt 111 presses the sealing ring 140 on the other side of the insulating plate 121, thereby sealing the connection between the connecting piece and the terminal 108.

[0050] By installing the elastic component 130, the slide bar 131 can limit the insulating plate 121. When the power cord is disassembled, the spring 132 can press the insulating plate 121 in the opposite direction, so that the insulating plate 121 is released from the pressure on the wire terminal, realizing automatic separation and making it easy to pull out the wire. At the same time, the pressure of the spring 132 on the insulating plate 121 can position the insulating plate 121, so that the insulating plate 121 and the terminal 108 are kept at a sufficient distance, which makes it easy for the operator to accurately insert the wire terminal connector into the wiring hole 103, facilitating quick installation.

[0051] By inserting a screwdriver into the cross groove 134 on the external thread head 133 and rotating the external thread head 133, the external thread head 133 can be unscrewed from the first threaded hole 106, thereby facilitating the installation and disassembly of the elastic component 130 and the assembly of the structure during the production process.
