Description

Technical Field

[0001] This application relates to the field of socket equipment technology, and more specifically, to a resilient slider and a safety socket for use in a safety socket. Background Technology

[0002] In existing socket structures, to ensure safe use, a shielding plate is usually installed inside the safety socket, or the socket insert is placed deep inside the socket housing to reduce safety risks.

[0003] However, the shielding design poses a risk of mechanical damage during long-term use, and placing the socket socket too deep may result in loose connections, making it difficult to guarantee a stable and reliable power supply.

[0004] In addition, when the plug is inserted, the sliding slider inside the existing socket cannot properly cooperate with the plug prongs. In particular, the prongs cannot reliably contact the socket's internal sleeve during insertion. When the plug is removed, the slider can only provide physical isolation and cannot guarantee the effective reset of the slider. Utility Model Content

[0005] The purpose of this application is to provide an elastic slider and a safety socket for a safety socket, which can ensure that the slider effectively moves during the insertion and removal of the plug prongs, thereby achieving the purpose of plugging in to turn on the power and unplugging to turn off the power, and can realize the effective reset of the slider after the plug is removed.

[0006] To achieve the above objectives, in a first aspect, the present invention provides an elastic slider for a safety socket, the safety socket including a socket housing and an internal support, the socket housing being provided with a plurality of plug holes, each of the plug holes being provided with a corresponding socket slider, the socket slider being disposed in the internal support; The internal support is provided with a return spring for the socket slider to abut against, and the socket slider includes a guide portion for the plug prongs to abut against.

[0007] In an optional embodiment, the return spring includes a compression spring, a baffle is provided in the middle of the internal bracket, and the two ends of the return spring abut against the baffle and the socket slider.

[0008] In an optional embodiment, the internal support includes a support base and a support top cover, the support top cover being provided with a plug hole for the plug prong to enter, and the guide portion being positioned opposite to the plug hole.

[0009] In an optional embodiment, the lower part of the socket slider is provided with a power-connecting sleeve, which is fixedly installed in the internal bracket. The plug prongs can be inserted under the guidance of the guide portion and the socket slider is compressed by the return spring. The power-connecting sleeve is provided with a power-connecting clip for the plug prongs to be inserted into.

[0010] In an optional embodiment, the guide portion includes a top guide wall disposed on the top of the socket slider. The top guide wall has an inclined wall structure, which allows the socket prongs to abut and slide against it.

[0011] In an optional embodiment, the top guide wall is inclined from top to bottom and outward relative to the insertion direction of the plug prongs.

[0012] In an optional embodiment, the socket slider is made of an insulating material.

[0013] In an optional embodiment, the plug socket includes a two-hole socket and a three-hole socket, and the socket slider includes a two-hole slider and a three-hole slider that are separately configured. The top guide wall on the two-hole slider includes two sets, which can be respectively set to correspond to the two prongs of the two-hole plug; The top guide wall on the three-hole slider includes a set, and the set of top guide walls is configured to correspond to the ground wire plug of the three-hole plug.

[0014] In an optional embodiment, a switch spring is connected to the bottom of the power socket, and the end of the switch spring is elastically bent and disposed above the power PCB board. A liftable pressing component is provided between the socket slider and the end of the spring.

[0015] Secondly, the present invention provides a safety socket, including the elastic slider for the safety socket as described in any of the foregoing embodiments.

[0016] By incorporating a return spring within the internal support, the spring force of the return spring can keep the socket slider in its initial outermost position in a natural state where no plug is inserted.

[0017] By incorporating the guide portion on the socket slider, the plug prongs can abut against the guide portion during insertion. Simultaneously, during further insertion, the socket slider can overcome the spring force of the return spring and move inward toward the center of the internal bracket, thereby providing clearance for the plug prongs to be inserted downwards, thus ensuring the smoothness of the prong insertion action.

[0018] This invention ensures that the socket slider moves effectively during the insertion and removal of the plug prongs, thereby achieving the purpose of power on when plugged in and power off when unplugged, and realizing the effective reset of the socket slider after the plug is removed.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] The elastic slider for the safety socket in this application is mainly used during the insertion and removal of the plug into the socket. Specifically, it serves to shield the internal power-connecting sleeve 23 of the socket. It can elastically move during the insertion of the plug to provide clearance for the plug, and then re-shield itself after the plug is removed.

[0027] See Figure 1 and combined Figures 2-3 The safety socket of this utility model has a main structure including a socket housing 1 and an internal support 2 disposed in the socket housing 1.

[0028] The internal support 2 includes a support base shell 21 and a support top cover 22, which are mainly used to form the mounting base for most of the moving parts and electrical components.

[0029] The socket housing 1 includes a front cover 11 and a rear cover 12. The front cover 11 and the rear cover 12 are fastened together by ultrasonic welding, gluing, screws and sealing gaskets to form a sealed housing. It is mainly used to install the internal bracket 2, isolation component 5, switch spring 24, power connection PCB board 6 and wiring sleeve 61, etc.

[0030] The socket housing 1 is provided with multiple plug holes, including two-hole holes and three-hole holes. Each plug hole is provided with a corresponding socket slider 3, which is located in the internal bracket 2.

[0031] Specifically, the elastic slider in this application is mainly used on the safety socket. From the perspective of core functions, the safety socket includes a mechanical transmission structure, a switch isolation structure, and an electrical connection structure. The insertion of the plug drives the linkage of the mechanical transmission structure in the internal bracket 2, ultimately achieving electrical connection. When the plug is inserted into the safety socket, the user does not need to directly operate any switch, and the plug can automatically cut off the power and restore the insulation isolation state after being pulled out, effectively preventing electric shock.

[0032] The elastic slider in this application includes a socket slider 3 and a return spring 31. The following describes the basic structural composition of the safety socket and the specific cooperation relationship of the elastic slider in this application in conjunction with the socket slider 3 and the return spring 31.

[0033] The mechanical transmission structure consists of a socket slider 3 made of insulating material and a pressing component 4. The socket slider 3 is slidably mounted in the internal support 2. A return spring 31 is provided between the socket slider 3 and the internal support 2. The return spring 31 is specifically in the form of a compression spring. In the natural state where no plug is inserted, the elastic force of the return spring 31 keeps the socket slider 3 in the outermost initial position.

[0034] The plug socket includes a prong hole on the top cover 22 of the inner bracket 2 for the plug prong to enter. The lower part of the socket slider 3 is provided with a power-connecting sleeve 23, which is fixedly installed in the inner bracket 2. When the plug is inserted, under the action of the plug prong and the guidance of the guide part on the socket slider 3, the socket slider 3 can overcome the elastic force of the return spring 31 and move inward toward the middle of the inner bracket 2, thereby providing clearance space for the plug prong to be inserted downward, so that the plug prong is inserted into the power-connecting clip 26 of the power-connecting sleeve 23, and the plug prong and the power-connecting sleeve 23 are electrically connected.

[0035] After the plug is unplugged, the socket slider 3 can be pushed to return to its initial outermost position by the elastic force of the return spring 31.

[0036] The pressing component 4 has its own reset elasticity, is vertically and vertically disposed on the side of the power-connecting socket 23, and is also disposed below the socket slider 3, and can move up and down during the translation of the socket slider 3.

[0037] Specifically, in conjunction with the translation process of the socket slider 3 described above, while translating inward, the pressing component 4 can move downward under the linkage of the inward translation of the socket slider 3. The pressing component 4 is provided with an isolation component 5 and a switch spring 24 below it. The bottom of the power-connecting sleeve 23 is provided with a power-connecting copper nail 25. The power-connecting copper nail 25 extends downward and outward from the internal support 2. The root of the switch spring 24 is riveted to the power-connecting copper nail 25. The end of the spring can be flexibly bent and is located above the power-connecting PCB board 6. The power-connecting sleeve 23, the switch spring 24 and the power-connecting PCB board 6 constitute an electrical connection structure.

[0038] When the pressing component 4 moves downward, it can press the switch isolation pad 51 of the isolation component 5 and the end of the spring of the switch spring 24. The switch spring 24 can bend downward elastically based on the root rivet point, pressing the spring silver contact on the end of the spring into contact with the silver contact of the power-connecting PCB board 6. Combined with the electrical connection state of the plug and the power-connecting socket 23, the circuit of the plug, the power-connecting socket 23, the switch spring 24 and the power-connecting PCB board 6 is connected.

[0039] After the socket slider 3 is moved and reset, the pressing component 4 can break free from the downward pressure of the socket slider 3 and perform a lifting action under its own elasticity. At the same time, under the reset elasticity of the switch isolation pad 51 and the switch spring 24, it can rebound upward from the bottom of the pressing component 4, thereby disconnecting the contact with the silver contacts on the power-connecting PCB board 6 and disconnecting the power supply. Furthermore, the upward rebound of the switch isolation pad 51 and the switch spring 24 can also lift the pressing component 4 to a certain extent, ensuring the elastic reset of the pressing component 4.

[0040] The plug sockets in this application include two-hole sockets and three-hole sockets. Each socket is provided with a sliding component. The sliding component specifically includes a socket slider 3, which is provided with a two-hole slider 3a and a three-hole slider 3b respectively.

[0041] A baffle is provided in the middle of the inner support 2 (located in the middle of the inner side of the inner support 2, not shown in the figure). Return springs 31 are respectively provided between the two-hole slider 3a and the baffle, and between the three-hole slider 3b and the baffle. The two ends of the return springs 31 abut against the socket slider 3 and the baffle respectively.

[0042] In its natural state, the return spring 31 forces the two-hole slider 3a and the three-hole slider 3b to elastically compress towards both sides away from the baffle.

[0043] Each plug socket includes a prong hole provided on the top cover 22 of the bracket, and the guide portion on the socket slider 3 is positioned opposite to the prong hole.

[0044] As described above, by inserting or removing the plug, combined with the guide portion on the socket slider 3, the socket slider 3 can be moved at an angle. The guide portion includes a top guide wall 32 in the form of an inclined wall at the top of the socket slider 3. Furthermore, the top guide wall 32 is inclined from top to bottom and outward relative to the insertion direction of the plug prongs, so that the top guide wall 32 can be abutted by the inserted plug prongs, and guide the socket slider 3 to move towards the center of the bracket when the plug prongs are inserted.

[0045] The pressing component 4 in this application includes various different configurations. In one specific configuration, the pressing component 4 includes a deflectable pressing frame 41. The translation of the socket slider 3 can be converted into the up-and-down deflection of the pressing component 4, thereby realizing the overall up-and-down lifting action.

[0046] From the perspective of deflection, the pressing bracket 41 includes a connecting pin 42 located at the root, and elastic claws 43 that can respectively cooperate with the socket slider 3 and the switch spring 24. The elastic claws 43 include a top claw 43a and a bottom claw 43b. Specifically, the top claw 43a is located at the top position and can abut against the bottom of the socket slider 3, and the bottom claw 43b is located at the top position and can abut against the top of the switch isolation pad 51.

[0047] A bending allowance notch 43c is provided between the top claw 43a and the bottom claw 43b to provide elasticity. The bending allowance notch 43c allows a certain range of elastic compression to occur between the top claw 43a and the bottom claw 43b.

[0048] Based on the above-mentioned abutting and cooperating relationship, the top claw 43a is provided with an inclined guide wall 43d that can abut and cooperate with the socket slider 3, and the bottom claw 43b is provided with a pressing protrusion 44 that can press the switch spring 24, or more specifically, the switch isolation pad 51 and the switch spring 24.

[0049] In order to address the angle at which the translation of the socket slider 3 can press down on the pressing component 4, the socket slider 3 also includes a translation pressing wall 33 disposed at the bottom of the socket slider 3. The translation pressing wall 33 is parallel to the translation direction of the socket slider 3. The front end of the translation pressing wall 33 is provided with an arc-shaped chamfer 34 that can contact and cooperate with the inclined guide wall 43d. Through the arrangement of the arc-shaped chamfer 34, the smooth sliding cooperation between the bottom translation pressing wall 33 of the socket slider 3 and the top claw 43a inclined guide wall 43d can be ensured, avoiding the risk of jamming.

[0050] During the centering and translation process, the socket slider 3 can cause the pressing frame 41 to deflect with the connecting pin 42 as the base point through the cooperation of the translation pressing wall 33 and the inclined guide wall 43d. In the process of deflection, the pressing protrusion 44 presses down on the switch isolation pad 51 and the switch spring 24, so that the silver contact contacts make contact and connect the power supply.

[0051] When the socket slider 3 moves inward, it can press the pressing bracket 41 and cause the pressing protrusion 44 on the bottom claw 43b to press down on the switch isolation pad 51 and the end of the spring piece. After the end of the spring piece is elastically bent, the spring piece silver contact on the end of the spring piece is pressed into contact with the silver contact on the power-connecting PCB board 6, so as to realize the circuit conduction.

[0052] When the socket slider 3 moves outward to reset, it can release the pressure on the pressing bracket 41, and the pressing protrusion 44 on the bottom claw 43b can be lifted by the elastic force of the switch spring 24 and the switch isolation pad 51, further driving the pressing bracket 41 to be lifted and reset as a whole. After the spring end and the switch isolation pad 51 are elastically reset, the spring silver contact on the spring end will be disengaged from the contact of the silver contact on the power-connecting PCB board 6, thus realizing the circuit power-off.

[0053] To ensure that the pressing frame 41 can deflect effectively, a hinge base 27 is fixedly installed in the internal bracket 2. The hinge base 27 is provided with a locking groove for installing the connecting pin 42. The two ends of the connecting pin 42 are locked in the locking groove, so that the connecting pin 42 is locked in the locking groove, ensuring that the deflection action of the pressing frame 41 can be converted into an effective pressing action on the switch isolation pad 51.

[0054] The two-hole slider 3a includes a connecting plate located in the middle, a top guide wall 32 and a translational pressing wall 33, which are two sets disposed on both sides of the connecting plate. The two sets of top guide walls 32 and translational pressing walls 33 are respectively disposed with the plug prongs of the two-hole socket, the live wire pressing assembly 4 and the neutral wire pressing assembly 4.

[0055] Specifically, the top guide wall 32 can simultaneously abut and cooperate with the prongs of the two-hole plug, and the sliding pressing wall 33 can simultaneously cooperate and slide with the inclined guide wall 43d of the live wire pressing component 4 and the neutral wire pressing component 4.

[0056] The two ends of the return spring 31 abut against the baffle in the middle of the connecting plate and the internal bracket 2, and can control the two hole sliders 3a to move during the plug insertion and removal process.

[0057] The two-hole slider 3a acts as a safety baffle to prevent small objects from entering the socket. When the switch activates the socket slider 3 and the plug is inserted, the two metal prongs of the plug (live and neutral wires) push the socket slider 3 to move. The sliding pressing wall 33 on the socket slider 3 simultaneously presses down the two sets of pressing components 4. The pressing bracket 41 deflects, causing the pressing protrusion 44 on the bottom claw 43b to pass through the through hole on the bracket bottom shell 21 and push against the switch isolation pad 51 and the switch spring 24, thereby making the silver contact at the end of the spring contact with the silver contact on the PCB board, achieving the purpose of connecting the power.

[0058] When the plug is unplugged, the return spring 31 pushes the socket slider 3 back, and at the same time, the pressing component 4 rises under the elastic action of the switch isolation pad 51, and the switch spring 24 also springs back to its original position, thereby disconnecting the contact with the silver contacts on the PCB and disconnecting the power supply.

[0059] The socket slider 3 also includes a three-hole slider 3b corresponding to the three-hole socket, the top guide wall 32 includes a set corresponding to the ground wire plug, and the translational pressing wall 33 includes two sets corresponding to the neutral wire and the live wire respectively. Specifically, one set of top guide walls 32 is corresponding to the ground wire plug of the three-hole plug, and the two sets of translational pressing walls 33 are respectively corresponding to the live wire pressing component 4 and the neutral wire pressing component 4.

[0060] The top guide wall 32 can abut and cooperate with the ground wire plug of the three-hole plug, and the sliding pressing wall 33 can simultaneously cooperate with the inclined guide wall 43d of the live wire pressing component 4 and the neutral wire pressing component 4 to slide.

[0061] The two ends of the return spring 31 abut against the middle baffle of the three-hole slider 3b and the internal support 2, and can control the three-hole slider 3b to move during the plug insertion and removal process.

[0062] The three-hole slider 3b also acts as a safety baffle, preventing small objects from entering the socket. When the switch activates the socket slider 3, and the three-prong plug is inserted, the metal prong of the plug's ground wire pushes the socket slider 3 to move. The sliding pressing wall 33 on the socket slider 3 simultaneously presses down two sets of pressing components 4. The pressing bracket 41 deflects, causing the pressing protrusion 44 on the bottom claw 43b to pass through the through hole on the bracket bottom shell 21 and press against the switch isolation pad 51 and the switch spring 24, thereby making the silver contact at the end of the spring contact with the silver contact on the PCB board, achieving the purpose of connecting the power. When the plug is unplugged, the process of disconnecting the power is the same as that of the two-hole slider 3a.

[0063] This utility model also provides a safety socket, including the elastic slider for the safety socket described above. The safety socket with elastic slider in this application can avoid the mutual influence between different socket holes to the greatest extent, thus avoiding safety risks. At the same time, it can realize the reliable application of plugging in to turn on the power and unplugging to turn off the power, preventing electric shock. In addition, the mechanical action of plug insertion can trigger the internal electrical connection mechanism, thereby realizing the active anti-electric shock function of no power supply when not inserted, and ensuring the stability and reliability of the power supply process.

[0064] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
