Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically a waterproof switch for sockets. Background Technology

[0002] Currently, most socket switches on the market use a rocker switch design. This type of switch mainly consists of a base, a rocker, and a button assembly: the base is equipped with a support for the rocker, which can deflect around the support. When the button assembly is pressed, indirect force is applied to deflect the rocker, thereby connecting or disconnecting its contacts with the terminal assembly on the base, realizing the switch's on / off state. However, existing waterproof sockets typically only have a waterproof structure on the socket body, while the switch area lacks waterproof functionality. Due to the frequent on / off switching of rocker switches, electric arcs can easily be generated during the switching process. Once these sparks come into contact with outside air, they may ignite external flammable gases, causing a safety accident and posing a significant safety hazard. Utility Model Content

[0003] This utility model provides a waterproof switch with a simple structure and good safety, which can effectively improve the safety during use, while also having good waterproof function, and can meet the use needs in various complex environments.

[0004] The waterproof switch of this utility model includes a base installed in a socket, wherein the base has a support for connecting an external power supply live wire and a bridge rocker electrically connected to the support; it also includes a switch sleeve that drives the bridge rocker to swing left and right around the support to achieve conduction or disconnection with the copper strip connected to the live wire, wherein the switch sleeve has a spring and a spring pin, the end of the spring pin protruding from the switch sleeve and maintaining close contact with the surface of the switch bridge under the action of the spring; it also includes a switch toggle for moving the switch sleeve to make the bridge rocker swing around the support; a waterproof rubber sleeve that is elastic and abuts against the switch sleeve is provided between the base and the toggle switch, the base and the socket together clamp the edge of the waterproof rubber sleeve, and the switch toggle contacts the waterproof rubber sleeve to move the switch sleeve.

[0005] The aforementioned waterproof switch achieves power connection and conductivity by incorporating a support member within the base for connecting an external power supply live wire and a bridge rocker plate conductively connected to the support member. The switch sleeve drives the bridge rocker plate to swing left and right around the support member, thereby connecting or disconnecting the bridge rocker plate from the live wire copper strip, controlling the circuit's on / off state. The spring and spring pin inside the switch sleeve maintain tight contact with the switch bridge surface under spring force, ensuring reliable and stable conductivity. Furthermore, a waterproof sleeve between the base and the socket securely supports the switch sleeve, preventing external liquids and small objects from entering the base and avoiding corrosion of components and electrical leakage. The waterproof sleeve also prevents electric arc sparks generated during power switching from contacting the outside air, preventing burns or ignition of flammable gases. The switch lever is in close contact with the waterproof sleeve; moving the switch lever pushes the waterproof sleeve, causing the switch sleeve to swing and the bridge rocker plate to swing around the support member, ensuring the normal operation of the switch function. This utility model has good waterproof performance. Because the waterproof sleeve and the switch sleeve are tightly supported, the switch toggle can be replaced and installed as an independent module in sockets that require different switching methods, such as movable switches or push-button switches, thus having a wide range of applications.

[0006] As a preferred embodiment of this utility model, the top center of the cross-section of the waterproof sleeve is recessed downward to form a recess for accommodating the switch sleeve.

[0007] As a preferred embodiment of this utility model, the edge of the waterproof rubber sleeve is provided with a circumferential rim for clamping the base and the socket.

[0008] As a preferred embodiment of this utility model, the switch sleeve is provided with a crossbar embedded in a recess.

[0009] As a preferred embodiment of this utility model, the switch lever is provided with two levers located on both sides of the switch sleeve, and the waterproof sleeve is provided with receiving grooves on both sides of the recess for the levers of the switch lever to extend into.

[0010] As a preferred embodiment of this utility model, the waterproof sleeve is made of high-temperature resistant silicone rubber.

[0011] As a preferred embodiment of this utility model, silver contacts are provided on the opposite side of the bridge rocker and the copper sheet connecting the live wire.

[0012] As a preferred embodiment of this utility model, the socket includes a front cover and a rear cover, the waterproof sleeve is installed between the base and the front cover, and a conductor isolation plate for isolating the live wire, ground wire and neutral wire is provided between the base and the rear cover.

[0021] like Figure 1-4 As shown, a waterproof switch includes a base 2 installed inside a socket 1. The base contains a support 3 for connecting an external power supply live wire, and a bridge rocker 4 electrically connected to the support. It also includes a switch sleeve 6 that drives the bridge rocker to swing left and right around the support to achieve connection or disconnection with the copper sheet 5 connected to the live wire. The switch sleeve contains a spring 7 and a spring pin 8, the end of which protrudes from the switch sleeve and maintains close contact with the surface of the bridge rocker under the force of the spring. It also includes a switch lever 9 for toggling the switch sleeve to make the bridge rocker swing around the support. A waterproof rubber sleeve 10, which is elastic and abuts against the switch sleeve, is provided between the base and the switch. The base and the socket together clamp the edge of the waterproof rubber sleeve. The switch lever contacts the waterproof rubber sleeve and is used to toggle the switch sleeve. The waterproof switch, by providing a support for connecting an external power supply live wire and a bridge rocker electrically connected to the support within the base, achieves power connection and conductivity. The switch sleeve drives the bridge rocker to swing left and right around the support, thereby connecting or disconnecting the bridge rocker and the copper strip connecting the live wire, controlling the circuit's on / off state. The spring and pin inside the switch sleeve maintain tight contact with the bridge surface under spring force, ensuring reliable and stable conductivity. Furthermore, a waterproof sleeve between the base and the socket securely supports the switch sleeve, preventing external liquids and small objects from entering the base, avoiding corrosion of components and potential electrical leakage. The waterproof sleeve also prevents electric arc sparks generated during power switching from contacting the outside air, preventing burns or ignition of flammable gases. The switch lever is in close contact with the waterproof sleeve; moving the switch lever pushes the waterproof sleeve, causing the switch sleeve to swing, which in turn causes the bridge rocker to swing around the support, ensuring normal switching functionality. This invention has excellent waterproof performance and can be installed as an independent module in sockets requiring different switching methods, such as movable switches or push-button switches, making it widely applicable.

[0022] The waterproof sleeve 10 has a recess 11 formed by the downward inward concavity at the top center of its cross-section, which is used to accommodate the switch sleeve. The shape of the recess matches the switch sleeve, enabling the switch sleeve to be accurately positioned within the recess. When the switch lever drives the switch sleeve to swing left and right, the recess can provide a fulcrum for the tilted sleeve, ensuring that the switch sleeve remains stable during operation and avoiding poor contact or circuit failure caused by shaking or displacement.

[0023] The waterproof sleeve 10 has a circumferential edge 17 for clamping the base and the socket. By setting the edge of the waterproof sleeve, the contact area between the edge of the waterproof sleeve and the base and the socket can be increased, and the fit between the three can be enhanced, thereby ensuring that the base and the socket can clamp the waterproof sleeve more firmly, effectively improving the overall sealing performance and stability.

[0024] The switch sleeve 6 is provided with a crossbar 12 embedded in a recess. By setting the crossbar, the contact area between the switch sleeve and the recess can be increased, which can effectively enhance the connection stability between the switch sleeve and the waterproof sleeve, prevent the switch sleeve from shifting or loosening due to external force or vibration during operation, and ensure the normal operation of the switch.

[0025] The switch lever has two levers 13 located on both sides of the switch sleeve. The waterproof sleeve has receiving grooves 14 on both sides of the recess for the levers of the switch lever to extend into. Installation and positioning are completed simply by inserting the levers of the switch lever into the receiving grooves. The receiving grooves provide stable support and positioning for the levers of the switch lever, ensuring that when the switch lever is moved, the lever can push the waterproof sleeve to deform and thus move the switch sleeve, achieving precise control and operation.

[0026] Furthermore, when the toggle switch is a movable switch, the crossbar on the switch sleeve can serve as a pivot mounted on the base. When the lever of the switch toggle moves the switch sleeve, the switch sleeve swings and tilts around the crossbar, thereby enabling the connection or disconnection of the bridge rocker and the copper sheet connecting the live wire, thus controlling the on / off state of the circuit.

[0027] The waterproof sleeve is made of high-temperature resistant silicone rubber, which not only has excellent heat resistance, but also excellent electrical insulation, good elasticity and resistance to compression deformation, as well as excellent waterproof performance.

[0028] The bridge rocker and the copper strip connecting the live wire are both provided with silver contacts 15 on opposite sides to ensure good conductivity.

[0029] The socket 1 includes a front cover 101 and a rear cover 102. A waterproof sleeve is installed between the base and the front cover. A conductor isolation plate 16 for isolating the live wire, ground wire, and neutral wire is provided between the base and the rear cover. The waterproof sleeve installed between the base and the front cover can effectively prevent external moisture or liquid from entering the base, further enhancing the waterproof performance. The conductor isolation plate between the base and the rear cover is used to isolate the live wire, ground wire, and neutral wire, which can prevent short circuits or leakage between them, improve safety, and avoid safety accidents caused by poor wiring contact or short circuits.
