Description

Technical Field

[0001] The utility model relates to the technical field of moisture-proof power switches, and particularly relates to a moisture-proof power switch. Background Art

[0002] A moisture-proof power switch is a special power switch that can work normally in a humid environment. It prevents moisture from entering the circuit through specific designs and materials, thus avoiding dangers caused by circuit short-circuit or internal moisture absorption of electrical appliances. In a humid environment, the circuit of an electrical appliance is prone to moisture absorption, resulting in short-circuit and even fire. The main function of a moisture-proof power switch is to prevent moisture in the circuit from entering, ensuring that the electrical appliance can still work safely and stably in a humid environment, which is particularly important for environments with high humidity such as bathrooms and kitchens.

[0003] However, in the prior art, due to factors such as long-term exposure to a humid environment, ultraviolet radiation, and temperature changes, over time, the waterproof plastics, sealants, etc. of the moisture-proof power switch may gradually age and lose their original waterproof performance. The seals of the switch may wear, break, or become loose during long-term use, resulting in a decline in moisture-proof performance. Once the humid water enters the switch interior, it is easy to reduce the insulation performance of the circuit, leading to short-circuit. The short-circuit may not only damage the switch itself but also cause damage to the connected electrical equipment. Therefore, we need a moisture-proof power switch. Content of the Utility Model

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] The embodiment of the present utility model provides a moisture-proof power switch, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, it includes a housing 1. A fixing component 2 is arranged inside the housing 1. A base 3 is combined and connected to the bottom of the housing 1. A pressing piece 4 is bolted to the top of the base 3. A wire 5 is arranged at the bottom of the pressing piece 4. A moisture-proof component 6 is arranged at the top of the housing 1. A button 7 is arranged at the top of the housing 1. The moisture-proof component 6 includes a first spring 601. A connecting plate 602 is fixedly connected to the top of the first spring 601. The base 3 and the connecting plate 602 form an elastic structure through the first spring 601, and the first spring 601 is arranged between the base 3 and the connecting plate 602. The connection effect between the base 3 and the first spring 601 is strengthened, so that the first spring 601 can limit the connecting plate 602 under the support of the base 3. A first contact block 603 is fixedly connected to one side of the connecting plate 602. A desiccant 604 is arranged at the top of the first contact block 603. A mounting bracket 605 is fixedly connected to the top of the base 3. A second spring 608 is fixedly connected inside the mounting bracket 605. A support plate 606 is fixedly connected to the bottom of the second spring 608. The mounting bracket 605 and the support plate 606 form an elastic structure through the second spring 608, and the bottom end of the second spring 608 is fixed to the top end of the support plate 606, and the top end of the second spring 608 is fixed to the inside of the mounting bracket 605. The connection effect between the mounting bracket 605 and the second spring 608 is strengthened, so that the second spring 608 can limit the support plate 606 under the support of the mounting bracket 605, and the support plate 606 has a reset function. A second contact block 607 is fixedly connected to one side of the support plate 606. A connecting rod 609 is rotatably connected to the outer wall of the mounting bracket 605. A positioning rod 610 is fixedly connected to the top of the connecting rod 609. A limiting block 611 is fixedly connected to one side of the support plate 606. The support plate 606 and the connecting rod 609 form a movable structure through the limiting block 611, and the positioning rod 610 on the connecting rod 609 can slide in the groove of the limiting block 611. The connection effect between the support plate 606 and the limiting block 611 is strengthened, so that when the support plate 606 moves, it can drive the limiting block 611 to move, and the positioning rod 610 on the connecting rod 609 can slide and be limited in the limiting block 611. Furthermore, after the button 7 is pressed, the purpose of limiting can be achieved. A connecting rod 612 is fixedly connected to the top of the support plate 606. If the internal environment is relatively humid, and relying on the set desiccant 604, it can absorb water and expand. After a long time, when the desiccant 604 expands to a certain extent, it contacts the bottom of the support plate 606. During the continuous expansion process, it pushes the support plate 606 upward to drive the second contact block 607 to move upward, and pushes the connecting plate 602 downward to drive the first contact block 603 to move downward. Thus, the disconnection of the switch can be achieved. At this time, the operator can replace and use the desiccant 604, and reduce the situation of power supply damage.

[0023] In a further preferred embodiment of the present invention, such asFigure 1 , Figure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 , Figure 4 , the fixing component 2 includes a washer 201. An inner rubber pad 202 is snap - connected to the inside of the outer shell 1. A threaded port 203 is sleeved on one side of the inner rubber pad 202. An outer rubber pad 204 is sleeved inside the threaded port 203. Both the inner rubber pad 202 and the outer rubber pad 204 are arranged on the outer wall of the electric wire 5. And the inner rubber pad 202 is installed on the inner wall of the outer shell 1, and the outer rubber pad 204 is installed on the outer wall of the outer shell 1. This facilitates the arrangement of the inner rubber pad 202 and the outer rubber pad 204. The inner rubber pad 202 and the outer rubber pad 204 can improve the limitation and sealing performance of the electric wire 5. At the same time, the inner rubber pad 202 and the outer rubber pad 204, as key moisture - proof structures, are arranged on both sides of the outer shell 1 to provide double protection, enhance the moisture - proof performance of the switch, and effectively isolate moisture, water and other impurities in the external environment from entering the inside of the switch, protecting the electric wire 5 and the circuit it is connected to from damage. Depending on the inner rubber pad 202 and the outer rubber pad 204 arranged on both sides of the electric wire 5, when subjected to external force or vibration, the inner rubber pad 202 and the outer rubber pad 204 can play a buffering role, reducing the direct friction and impact between the electric wire 5 and the outer shell 1 and extending the service life. The outer wall of the threaded port 203 is thread - connected to a screw sleeve 205. The outer shell 1 and the electric wire 5 form a limiting structure through the screw sleeve 205, and the screw sleeve 205 is sleeved on the outer wall of the threaded port 203 for fastening, enhancing the connection strength between the outer shell 1 and the electric wire 5 and ensuring the stability and reliability of the connection. When the screw sleeve 205 rotates and is tightened on the threaded port 203, a strong fastening force will be generated to firmly fix the electric wire 5 on the outer shell 1. This fastening connection method can effectively prevent the electric wire 5 from loosening or falling off during use. The threaded connection can effectively prevent moisture and water from seeping into the switch through the connection. The fastening effect of the screw sleeve 205 further enhances this moisture - proof and sealing effect.

[0024] Working principle: After installing the wire 5, the wire 5 can penetrate through the reserved hole of the housing 1 and extend outwards. At this time, the inner rubber pad 202 and the outer rubber pad 204 can be unfolded and clamped outside the wire 5. At this time, the screw sleeve 205 and the threaded port 203 are respectively arranged on the outer side and the inner side of the housing 1, and the inner rubber pad 202 and the outer rubber pad 204 are arranged on the inner and outer sides of the housing 1. At this time, the screw sleeve 205 can be butted against the threaded port 203, and by rotating the screw sleeve 205, the screw sleeve 205 can be fastened to the threaded port 203 tightly, so as to firmly fix the wire 5 on the housing 1. The fastening connection method can effectively prevent the wire 5 from loosening or falling off during use. In addition, after installing the wire 5, the housing 1 can be clamped on the base 3 for limit installation, and relying on the gasket 201 between the housing 1 and the base 3, the sealing and waterproof performance of the power switch can be further improved. In addition, when the power switch needs to be turned on, by pressing the button 7 downwards, the button 7 can drive the connecting rod 612 to apply pressure downwards on the support plate 606, so that the support plate 606 can drive the second contact blocks 607 on both sides to move downwards to contact the first contact block 603 and conduct electricity. And at this time, during the downward movement of the support plate 606, the limiting block 611 will be driven to move downwards, so that the positioning rod 610 in the limiting block 611 will slide under force. Then, supported by the connecting rod 609, the positioning rod 610 can be stuck in the top groove of the limiting block 611 for limit, thus completing the turning on of the switch. In addition, if the internal environment is relatively humid, and relying on the set desiccant 604 which can absorb water and expand, and after a long time, when the desiccant 604 expands to a certain extent, it will contact the bottom of the support plate 606, and during the continuous expansion process, it will push the support plate 606 upwards to drive the second contact block 607 to move upwards, and push the connecting plate 602 downwards to drive the first contact block 603 to move downwards, so as to achieve the disconnection of the switch. At this time, the operator can replace the desiccant 604 for use and reduce the situation of power damage.
