Description
Technical Field
[0001] This utility model relates to the field of rocker switch technology, and more specifically, to a high-power rocker switch. Background Technology
[0002] Rocker switches, as common circuit switching devices, consist of an operation panel, moving contacts, and stationary contacts. Current control is achieved by pressing to drive the contacts to make or break contact. This device employs a lever principle design; when external force is applied to the rocker panel, its internal linkage mechanism drives the moving contact to either connect or disconnect with the stationary contact. This mechanical switching method is widely used in household appliances, industrial equipment, and lighting systems due to its intuitive operation and compact structure.
[0003] Currently, under some high-load conditions, such as when charging household electric vehicles, the switch of the charging pile experiences continuous high current flow. Due to its low heat dissipation efficiency, the internal conductive sheet will continuously heat up under high current conditions, and the insulation performance of the plastic parts in contact with the conductive sheet will decrease accordingly, greatly increasing the risk of leakage at the switch connection point of the electrical equipment. Utility Model Content
[0004] The purpose of this invention is to overcome the risk of leakage due to poor heat dissipation in existing rocker switches under high current and high load conditions, and to provide a high-power rocker switch that can effectively improve the heat dissipation of conductive components and prevent leakage in high-power electrical equipment.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A high-power rocker switch is provided, comprising a base, a rocker assembly, a button assembly, and a wiring assembly. The rocker assembly is installed inside the base, the wiring assembly is installed at the bottom of the base and connected to the rocker assembly, the button assembly is installed on the top surface of the base and abuts against the rocker assembly, and a grounding component is also provided. The base has heat dissipation holes that connect to at least part of the location of the rocker assembly. The top surface of the base has a threaded mounting hole, and the bottom surface of the base has a grounding post. One end of the grounding component is connected to the grounding post, and the other end is installed in the threaded mounting hole.
[0007] In the operation of the above scheme, the wiring assembly is connected to the live wire and the neutral wire, and the grounding post is connected to the ground wire. The bottom shell of the entire rocker switch is threadedly connected to the metal shell of the electrical equipment through the threaded mounting holes. When the button assembly is pressed, the button assembly pushes the rocker assembly into the closed connection state. The rocker assembly is a conductive element that will continuously flow with a large current and generate heat. The heat generated is slowly dissipated through the heat dissipation holes on the bottom shell. When a high-power electrical equipment controlled by the switch leaks current at the switch connection point, the charge on the metal shell of the electrical equipment will flow through the bolt, grounding component, and grounding post into the grounding wire and finally into the earth, effectively preventing electrical equipment leakage from causing safety accidents.
[0008] Furthermore, the grounding component has a connecting lug at its end, and the threaded mounting hole has a countersunk groove at one end near the grounding component. The connecting lug is installed in the countersunk groove. When the connecting lug is installed in the countersunk groove, the bolt nut can better press the connecting lug and maintain good contact. At the same time, the bolt nut is located in the countersunk groove and will not protrude, which is more aesthetically pleasing.
[0009] Furthermore, the wiring assembly is provided in two sets, each including a live wire post and a neutral wire post. The bottom housing contains a cavity for mounting the live wire post, the neutral wire post, and the grounding post. The live wire post and neutral wire post adopt a columnar wiring form, with the main body made of copper. The columnar shape provides a large heat dissipation area, and copper has a high specific heat capacity, resulting in slow heating and better heat dissipation. The wiring assembly has a total of four posts (two sets of live wire posts and one set of neutral wire posts). In actual circuits, the two live wire posts are connected to the live wire input and output terminals respectively, and the two neutral wire posts are connected to the neutral wire input and output terminals respectively. This is superior to a system with only one set of live wire and neutral wire posts. In the conventional form where the switch is installed on the neutral wire side, the switch in this solution acts as a main switch for the electrical equipment. If both the neutral and ground wires are accidentally disconnected, and a user accidentally touches the metal casing of a high-load electrical device while standing on the ground, a potential difference will form between the live wire and the ground where the user is standing, and the current will instantly flow through the human body, causing electric shock. In this solution, the switch is installed at the power source of the electrical equipment, which can simultaneously disconnect the live and neutral wires connected to the electrical equipment, avoiding the risk of electric shock caused by the user accidentally touching the metal casing of the electrical equipment in the above situation. It has a better safety effect when used under high load and high current conditions.
[0010] Furthermore, it also includes an inner housing, which is installed in the cavity of the bottom shell and fixedly connected to the bottom shell. The inner housing is provided with a wiring groove, and the grounding component is installed in the wiring groove. One end of the grounding post abuts against the bottom surface of the inner housing, and the other end is installed in the receiving cavity. The wiring groove on the inner housing is specially designed for installing the grounding component to avoid short circuits caused by contact between the grounding component and other metal components.
[0011] Furthermore, it also includes an indicator light. The inner housing is provided with a mounting groove, and the indicator light is installed in the mounting groove. One end of the indicator light is electrically connected to the live wire post, and the other end is electrically connected to the neutral wire post. The indicator light is used to remind the user whether the live wire and neutral wire of the external power grid can supply power normally, which is convenient for the user.
[0012] Furthermore, the rocker assembly is also provided in two sets. One set of the rocker assembly includes a stationary contact plate, a movable rocker, and a conductive plate. One live wire post and one neutral wire post of the wiring assembly are respectively fixedly connected to one of the stationary contact plates, which are located on the bottom surface of the inner housing. The other live wire post and the other neutral wire post of the wiring assembly are respectively fixedly connected to one of the conductive plates, which are located on the bottom surface of the neutral wire post and the live wire post. The movable rocker is installed on the bottom surface of the cavity of the bottom housing and is rotatably connected to the bottom housing. Both live wire posts are located on the same side of the inner housing, and both neutral wire posts are located on the opposite side of the live wire post. When the switch is closed, the two ends of one movable rocker are respectively in contact with the two live wire posts, and the two ends of the other movable rocker are respectively in contact with the two neutral wire posts. The bottom surface of the stationary contact plate is provided with a stationary contact point, and the movable rocker plate is equipped with a movable contact point that can contact the stationary contact point. The entire rocker plate assembly adopts a "reverse-flip" structural design. Only when the end of the movable rocker plate with the movable contact point is tilted upward will it abut against the stationary contact point. Under high load and high current conditions, when the movable contact point is about to detach from the stationary contact point, an electric spark is easily generated between the movable contact point and the stationary contact point. Since electric contacts are often made of silver metal, and silver has a low melting point, while the temperature generated by the electric spark is extremely high, the high temperature can instantly burn the stationary contact point and the movable contact point, causing them to sinter together. By adopting a reverse-flip structure, the movable contact point can accelerate its detachment from the stationary contact point under the assistance of gravity, effectively reducing the risk of the stationary contact point and the movable contact point sintering together. At the same time, because the contact point detaches quickly, the electric spark ignition time is short, and the heat generation is small. The thickness of the silver contact point can be made relatively thinner, effectively saving materials and reducing costs.
[0013] Furthermore, the bottom surface of the inner housing is provided with a first protrusion, which abuts against the side of the stationary contact plate away from the stationary contact point. Due to structural design, there is a certain gap between the surface of the stationary contact plate and the bottom surface of the inner housing. If the moving contact presses against the stationary contact point, the stationary contact plate will bend due to lack of support, reducing the contact effect. The first protrusion provides support for the stationary contact plate and prevents it from bending.
[0014] Furthermore, the cavity of the bottom shell is provided with a vertical wall, the movable rocker plate is provided with a second protrusion, the vertical wall and the inner wall of the bottom shell are provided with a rotating groove, the second protrusion is connected to the rotating groove, and the top of the conductive plate abuts against the movable rocker plate; the rotating groove can be an annular hole, the second protrusion can be a cylinder, the cylinder is inserted into the annular hole to achieve a rotating connection, and the rotating connection between the rotating groove and the second protrusion achieves smooth rotation with low resistance, which is convenient for users.
[0015] Furthermore, the stationary contact plate has a collar portion at the end away from the stationary contact point, and a shaft portion is provided on the live wire post and the neutral wire post. The collar portion is inserted into the shaft portion, and the shaft portion is fixedly connected to the inner housing. The conductive plate is riveted to the live wire post or the neutral wire post. The shaft portion and the inner housing can be connected by threads. A threaded ring is provided at the bottom of the inner housing. During installation, the shaft portion can be manually screwed into the threaded ring. The stationary contact plate adopts the form of installation of the collar portion and the shaft portion, which is convenient for workers to assemble. The conductive plate can be riveted to the live wire post or the neutral wire post, can be injection molded and embedded, or can be glued with adhesive. A permanent mechanical connection is made using rivets, which requires no maintenance and is suitable for high-strength and high-load applications.
[0016] Furthermore, the button assembly includes a button shell and an elastic part. The button shell is rotatably connected to the inner shell, and the elastic part abuts against the movable rocker. The elastic part may include a bullet groove, a spring, and a bullet head disposed in the button shell. One end of the spring is connected to the bottom of the bullet groove, and the other end is connected to the bullet head. The bullet head is slidably connected to the bullet groove, and the tip of the bullet head abuts against the movable rocker, so that the rocker can be pressed smoothly.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The bottom surface of the switch housing is also provided with heat dissipation holes, which can accelerate the cooling of conductive components. The top surface of the housing is provided with threaded mounting holes, and a grounding post is installed on the bottom surface of the housing. One end of the grounding component is connected to the grounding post, and the other end is installed on the threaded mounting hole. When a high-power electrical device controlled by the switch leaks current at the switch connection, the charge on the metal casing of the electrical device will flow through the bolt, grounding component, and grounding post into the grounding wire and finally into the ground, effectively preventing electrical leakage from causing safety accidents.
[0019] 2. The rocker assembly adopts a "reverse strike" structural design, which allows the moving contact to accelerate its separation from the stationary contact under the assistance of gravity. The contact separation speed is fast, the electric spark ignition time is short, and the heat generation is small, effectively reducing the risk of the stationary contact and the moving contact being sintered together. The thickness of the silver contact can be made thinner, effectively saving materials and reducing costs. Attached Figure Description

[0029] Example 1
[0030] This embodiment is a first embodiment of a high-power rocker switch, such as... Figures 1 to 5 As shown, the device includes a base shell 100, a rocker assembly 200, a button assembly 300, and a wiring assembly 400. The rocker assembly 200 is installed inside the base shell 100. The wiring assembly 400 is installed at the bottom of the base shell 100 and connected to the rocker assembly 200. The button assembly 300 is installed on the top surface of the base shell 100 and abuts against the rocker assembly 200. The device also includes a grounding component 500. The base shell 100 is provided with heat dissipation holes 110, which are connected to at least part of the rocker assembly 200. The top surface of the base shell 100 is provided with a threaded mounting hole 120. A grounding post 600 is installed on the bottom surface of the base shell 100. One end of the grounding component 500 is connected to the grounding post 600, and the other end is installed on the threaded mounting hole 120.
[0031] Specifically, the grounding component 500 has a connecting lug 510 at its end, and the threaded mounting hole 120 has a countersunk groove 121 at the end near the grounding component 500. The connecting lug 510 is installed in the countersunk groove 121. When the connecting lug 510 is installed in the countersunk groove 121, the bolt nut can better press the connecting lug 510 and maintain good contact. At the same time, the bolt nut is located in the countersunk groove 121 and will not protrude, which is more aesthetically pleasing.
[0032] The conductive components for heat dissipation through the heat dissipation holes 110 refer to the various parts included in the rocker assembly 200.
[0033] Specifically, the wiring assembly 400 has two sets, including a live wire post 410 and a neutral wire post 420. The bottom housing 100 has a receiving cavity 130 for installing the live wire post 410, neutral wire post 420, and grounding post 600. The live wire post 410 and neutral wire post 420 adopt a columnar wiring form, with the main body made of copper. The columnar shape has a large heat dissipation area, and copper has a high specific heat capacity, resulting in slow heating and better heat dissipation. The wiring assembly 400 has a total of four posts: two sets of live wire posts 410 and neutral wire posts 420. In the actual circuit, the two live wire posts 410 are connected to the live wire input and output terminals respectively, and the two neutral wire posts 420 are connected to the neutral wire input and output terminals respectively. Compared to... In a conventional setup with only one set of live wire post 410 and neutral wire post 420, and the switch installed on the neutral wire side, this solution's switch configuration acts as a main switch for the electrical equipment. If both the neutral and ground wires are accidentally disconnected, and a user accidentally touches the metal casing of a high-load electrical device while standing on the ground, a potential difference will form between the live wire and the ground, causing a sudden current flow and electric shock. This solution's switch, installed at the power source of the electrical equipment, can simultaneously disconnect both the live and neutral wires connected to the equipment, preventing the risk of electric shock from accidental contact with the metal casing in such situations. It offers better safety under high-load, high-current conditions.
[0034] Specifically, it also includes an inner housing 700, which is installed in the cavity of the bottom housing 100 and fixedly connected to the bottom housing 100. The inner housing 700 is provided with a wiring groove 710, and the grounding component 500 is installed in the wiring groove 710. One end of the grounding post 600 abuts against the bottom surface of the inner housing 700, and the other end is installed in the receiving cavity 130. The wiring groove 710 on the inner housing 700 is specially designed for installing the grounding component 500 to avoid short circuits caused by contact between the grounding component 500 and other metal components.
[0035] The working principle of a high-power rocker switch in this embodiment is as follows:
[0036] During installation, the two live wire posts 410 are connected to the input and output terminals of the live wire, the two neutral wire posts 420 are connected to the input and output terminals of the neutral wire, the connecting lug 510 of the grounding component 500 is installed in the countersunk groove 121, and the grounding post 600 is connected to the ground wire. When the current continuously passes through the various components of the rocker assembly 200, the rocker assembly 200 will continuously heat up. The heat is dissipated through the heat dissipation holes 110 in the form of convection heating radiation. When a high-power electrical device controlled by the switch leaks current at the switch connection, the charge on the metal casing of the electrical device will be conducted to the grounding post 600 through the bolts and connecting lug 510 and finally flow to the ground.
[0037] The beneficial effects of this embodiment are as follows: the heat dissipation hole 110 effectively improves the heat dissipation efficiency of the rocker assembly 200; the grounding component 500 and grounding post 600 are designed to add a ground wire connection structure inside the switch, effectively preventing electrical equipment leakage from causing safety accidents.
[0038] Example 2
[0039] This embodiment is a second embodiment of a high-power rocker switch, such as... Figures 5 to 6 As shown, the difference from Embodiment 1 is as follows:
[0040] Specifically, the rocker assembly 200 is also provided in two sets. One set of rocker assembly 200 includes a stationary contact plate 210, a movable rocker 220, and a conductive plate 230. A live wire post 410 and a neutral wire post 420 of the wiring assembly 400 are respectively fixedly connected to a stationary contact plate 210, which is located on the bottom surface of the inner housing 700. The other live wire post 410 and the other neutral wire post 420 of the wiring assembly 400 are respectively fixedly connected to a conductive plate 230. The conductive plate 230 is located on the bottom surface of the inner housing 700. On the bottom surfaces of the neutral wire post 420 and the live wire post 410, the movable rocker 220 is mounted on the bottom surface of the cavity of the bottom shell 100 and rotatably connected to the bottom shell 100; both live wire posts 410 are located on the same side of the inner shell 700, and both neutral wire posts 420 are located on the opposite side of the live wire posts 410. When the switch is closed, the two ends of one movable rocker 220 are respectively in contact with the two live wire posts 410, and the two ends of the other movable rocker 220 are respectively in contact with the two neutral wire posts 420. The stationary contact plate 210... The bottom surface is provided with a stationary contact 211, and the movable rocker 220 is equipped with a movable contact 221 that can contact the stationary contact 211. The entire rocker assembly 200 adopts a "reverse-flip" structural design. Only when the end of the movable rocker 220 with the movable contact 221 is tilted upward will it abut against the stationary contact 211. Under high load and high current conditions, at the moment when the movable contact 221 is about to disengage from the stationary contact 211, an electric spark is very likely to be generated between the movable contact 221 and the stationary contact 211. Since electric contacts are often made of silver metal, silver... With a low melting point and extremely high temperature generated by electric spark ignition, the high temperature can instantly burn the stationary contact 211 and the moving contact 221, causing them to sinter together. By adopting a reverse-firing structure, the moving contact 221 can accelerate its separation from the stationary contact 211 under the assistance of gravity, effectively reducing the risk of the stationary contact 211 and the moving contact 221 sintering together. At the same time, because the contact separation speed is fast and the electric spark ignition time is short, the heat generation is also small, and the thickness of the silver contact can be made relatively thinner, effectively saving materials and reducing costs.
[0041] like Figure 3 and 5As shown, in this embodiment, the two neutral terminals 420 are divided into an input neutral terminal and an output neutral terminal, and the two live terminals 410 are divided into an input live terminal and an output live terminal. The two input terminals of the live terminal 410 and the neutral terminal 420 are located on the same side of the inner housing 700, and the two output terminals are located on opposite sides of the input terminals. The neutral terminal 420 and the live terminal 410, which serve as input terminals, are equipped with stationary contact plates 210, while the neutral terminal 420 and the live terminal 410, which serve as output terminals, are equipped with conductive plates 230. When the switch is closed and energized, the moving contact 221 at one end of the moving rocker 220 contacts the stationary contact 211 on the stationary contact plate 210 at the input terminal, and the other end contacts the conductive plate 230 at the output terminal, so that the two neutral terminals 420 at the input terminal and the two live terminals 410 at the input terminal and the two live terminals at the output terminal are connected to each other.
[0042] Specifically, the bottom surface of the inner housing 700 is provided with a first protrusion 740, which abuts against the side of the stationary contact plate 210 away from the stationary contact point 211. Due to structural design, there is a certain gap between the surface of the stationary contact plate 210 and the bottom surface of the inner housing 700. If the moving contact point 221 presses against the stationary contact point 211, the stationary contact plate 210 will bend due to lack of support, reducing the contact effect. The first protrusion 740 provides support for the stationary contact plate 210 and prevents it from bending.
[0043] Specifically, a vertical wall 140 is provided inside the cavity of the bottom shell 100, and a second protrusion 222 is provided on the movable rocker 220. A rotating groove 800 is provided on the vertical wall 140 and the inner wall of the bottom shell 100. The second protrusion 222 is connected to the rotating groove 800, and the top of the conductive plate 230 abuts against the movable rocker 220. The rotating groove 800 can be an annular hole, and the second protrusion 222 can be a cylinder. The cylinder is inserted into the annular hole to achieve a rotating connection. The rotating connection between the rotating groove 800 and the second protrusion 222 achieves smooth rotation with low resistance, which is convenient for users.
[0044] Specifically, the stationary contact plate 210 has a collar portion 212 at the end away from the stationary contact point 211, and a sleeve portion 900 is provided on the live wire post 410 and the neutral wire post 420. The collar portion 212 is inserted into the sleeve portion 900, and the sleeve portion 900 is fixedly connected to the inner housing 700. The conductive plate 230 is riveted to the live wire post 410 or the neutral wire post 420. The sleeve portion 900 and the inner housing 700 can be connected by threads. A threaded ring is provided at the bottom of the inner housing 700. During installation, the sleeve portion 900 can be manually screwed into the threaded ring. The stationary contact plate 210 is installed in the form of collar portion 212 and sleeve portion 900, which is convenient for workers to assemble. The conductive plate 230 can be riveted to the live wire post 410 or the neutral wire post 420, can be injection molded and embedded, or can be glued. A permanent mechanical connection is made using rivets, which requires no maintenance and is suitable for high-strength and high-load applications.
[0045] The working principle of a high-power rocker switch in this embodiment is as follows:
[0046] When the switch is pressed down to close, the moving contact 221 moves upward and comes into contact with the stationary contact 211, and the switch is closed. When the switch is pressed down again to open, the rocker 220 rotates, and the moving contact 221 moves downward in the opposite direction. With the help of gravity, the moving contact 221 quickly separates from the stationary contact 211.
[0047] The beneficial effects of this embodiment are: the rocker assembly 200 adopts a "reverse strike" structural design, which effectively reduces the risk of the stationary contact 211 and the moving contact 221 being sintered together, and at the same time saves materials and reduces costs.
[0048] Example 3
[0049] This embodiment is a third embodiment of a high-power rocker switch, such as... Figure 2 and 6 As shown, the difference from Embodiment 1 is as follows:
[0050] Specifically, it also includes an indicator light 720. The inner housing 700 is provided with a mounting groove 730, and the indicator light 720 is installed in the mounting groove 730. One end of the indicator light 720 is electrically connected to the live wire post 410, and the other end is electrically connected to the neutral wire post 420. The indicator light 720 is used to remind the user whether the live and neutral wires of the external power grid can supply power normally, which is convenient for the user. In this embodiment, the wires of the indicator light 720 are pressed onto the live wire post 410 and the neutral wire post 420 respectively by the action of the inner housing 700, and the electrical connection is achieved by pressing, which reduces the assembly process and lowers the installation cost.
[0051] Specifically, the button assembly 300 includes a button shell 310 and an elastic part 320. The button shell 310 is rotatably connected to the inner shell 700, and the elastic part 320 abuts against the movable rocker 220. The elastic part 320 may include a bullet groove, a spring, and a bullet head disposed in the button shell 310. One end of the spring is connected to the bottom of the bullet groove, and the other end is connected to the bullet head. The bullet head is slidably connected to the bullet groove, and the tip of the bullet head abuts against the movable rocker 220 to make the rocker smooth to press.
[0052] The working principle of a high-power rocker switch in this embodiment is as follows:
[0053] After the live wire and neutral wire are connected to the live wire and neutral wire respectively, the indicator light 720 in the mounting slot 730 will light up, indicating that the power supply in the external power grid is normal, the live wire is energized, and the neutral wire in the power grid is not broken. At this time, pressing the button cover 310 will cause the elastic part 320 to press and drive the rocker arm 220 to open or close.
[0054] The beneficial effects of this embodiment are: through the design of the indicator light 720, in the event of a power failure, it is easy for users to determine whether the fault comes from the external power grid or from electrical equipment including switches.
[0055] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
