Description

Technical Field

[0001] The present application relates to the field of switches and sockets, and in particular to an anti-electric shock switch and socket. Background Art

[0002] Sockets are common electrical connection structures in people's daily lives. Taking a two-pin switch as an example, the switch mainly includes a housing, a master switch, a live wire and a neutral wire. The live wire and the neutral wire are both provided with wiring holes for the pins of the plug to be inserted, and the socket is provided with a jack for the pins to be inserted and corresponding to the wiring holes. In order to improve the safety performance of the socket when in use, and to prevent dust and other impurities from the outside from easily entering the socket through the jack when the socket is in use. A protective structure is generally provided in the socket, and the protective structure includes a rotatably arranged protective sheet and a reset spring. The protective sheet is located between the jack and the wiring hole, and the two ends of the protective sheet are used to block the two jacks of the socket, so that dust and other impurities from the outside are not easily entered into the jack when the socket is idle, and at the same time, fingers are not easily inserted into the jack, achieving a certain degree of protection.

[0003] When the pin is inserted into the jack, the pin pushes the protective sheet away, thereby inserting into the wiring hole and contacting the live wire sheet or the neutral wire sheet to achieve electrical connection. When the pin is pulled out of the jack, the protective sheet rotates and resets under the action of the reset spring, blocking the jack again.

[0004] With respect to the above-mentioned related technologies, the inventors have found the following defects: First, during the pin insertion process, the protective sheet rotates, and at this time, the spring is deformed and bent to a certain extent to cooperate with the rotation of the protective sheet. Since the spring is not deformed along its length direction, after repeated deformation, the elastic performance of the spring is reduced, and even irreversible deformation occurs, thereby affecting the rotation and resetting of the protective sheet; Second, when the plug is inserted into the socket, it is easy to be affected by external force, causing the plug to fall off the socket, thereby making the stability of the electrical connection poor. Summary of the invention

[0005] In order to increase the service life of the elastic mechanism and improve the stability of the connection between the plug and the socket, the present application provides an anti-electric shock switch socket.

[0006] The present application provides an anti-electric shock switch socket, which adopts the following technical solution:

[0007] A switch socket that prevents electric shock, comprises a shell, an elastic mechanism arranged in the shell, a neutral wire piece and a live wire piece arranged in the shell, a socket slot is provided on the shell, the neutral wire piece and the live wire piece are both provided with connecting holes, and the bottom of the socket slot is provided with two plug holes corresponding to the connecting holes, characterized in that: the elastic mechanism comprises a reset spring and two protective sheets for blocking the plug holes, the two protective sheets are respectively connected to the two ends of the reset spring, a guide block is provided on the protective sheet, the guide block has a guide inclined surface for abutting against a pin, and an elastic sheet for abutting against a plug is provided on the slot wall of the socket slot.

[0008] By adopting the above technical solution, when the pin is inserted into the jack, the pin pushes away the guide block and then inserts into the connection hole. At this time, the reset spring deforms along its length direction. Compared with the deformation of the entire spring bending, the reset spring in this normal deformation state has a longer service life. At the same time, the elastic sheet can squeeze the outer wall of the plug, making it more difficult for the plug to fall off the socket.

[0009] Optionally, a positioning hole corresponding to the connecting hole is formed on the protective sheet, and the positioning hole is located between the guide block and the return spring. The distance between the guide slope and the protective sheet gradually increases from one side close to the return spring to the other side, and the return spring has elastic potential energy that causes the two protective sheets to move closer to each other.

[0010] By adopting the above technical solution and providing the positioning holes, when the pins of the plug are inserted into the jack and the positioning holes, the positions of the two protection sheets are positioned, so that the two protection sheets can slide and move within a predetermined moving range.

[0011] Optionally, a clamping portion is provided on one end of the protective sheet extending away from the reset spring, a rotating rod is provided on the shell, the elastic sheet includes an abutting portion for abutting the plug and a force-bearing portion, the elastic sheet is rotatably sleeved on the rotating rod, the rotating rod is located between the abutting portion and the force-bearing portion, and the clamping portion is used to abut against the force-bearing portion.

[0012] By adopting the above technical solution, when the plug is inserted into the socket, the two protective sheets move away from each other, the pressing part pushes the force-bearing part, causing the elastic sheet to rotate, so that the abutting part can better abut the plug, making it difficult for the plug to fall off the socket.

[0013] Optionally, a positioning hole is provided inside the shell for the pressing part to slide through.

[0014] By adopting the above technical solution, the movement of the pressing part is smoother and the protection sheet can move along a straight line better.

[0015] Optionally, a guide piece is bent and provided at one end of the abutment portion away from the force-bearing portion.

[0016] By adopting the above technical solution, the plug can be inserted into the socket slot more smoothly.

[0017] Optionally, an elastic extrusion sheet is provided on the hole wall of the connecting hole, and the elastic extrusion sheet is used to abut against the outer side wall of the pin.

[0018] By adopting the above technical solution, the stability of the connection between the plug pin and the connecting hole is improved, and the electrical contact is better.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. When the pin is inserted into the jack, the pin pushes away the guide block and then inserts into the connection hole. At this time, the reset spring deforms along its length. Compared with the deformation of the entire spring bending, the reset spring in this normal deformation state has a longer service life. At the same time, the elastic sheet can squeeze the outer wall of the plug, making it more difficult for the plug to fall off the socket;

[0021] 2. By setting the positioning holes, when the pins of the plug are inserted into the jack and the positioning holes, the positions of the two protective sheets are positioned, so that the two protective sheets can slide and move within a predetermined moving range;

[0022] 3. When the plug is inserted into the socket, the two protective sheets move away from each other, and the pressing part pushes the force-bearing part, causing the elastic sheet to rotate, so that the abutting part can better abut the plug, making it difficult for the plug to fall off the socket.

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] The embodiment of the present application discloses an electric shock protection switch socket.

[0031] Reference Figure 1 and Figure 2 The anti-electric shock switch socket includes a housing 1, an elastic mechanism 2 arranged in the housing 1, a neutral wire piece 42 and a live wire piece 41 arranged in the housing 1. The housing 1 includes an upper housing 11 and a lower housing 12, and the upper housing 11 and the lower housing 12 can be fixed by snapping or fixed by screws. A socket slot 14 is provided on the upper housing 11, and connecting holes 43 are provided on the neutral wire piece 42 and the live wire piece 41. Two jacks 15 corresponding to the connecting holes 43 are provided at the bottom of the socket slot 14. A master control switch 13 is provided on the housing 1 to control the closing and opening of the socket as a whole.

[0032] Reference Figure 1 and Figure 2 When the anti-electric shock switch socket is used, the two pins of the plug are respectively inserted into the two jacks 15, and then inserted into the connecting hole 43, and contact the hole wall of the connecting hole 43. Since the neutral wire piece 42 and the live wire piece 41 are both made of copper material with good electrical conductivity, the pin part of the plug is electrically connected to the socket.

[0033] Reference Figure 3 The elastic mechanism 2 includes a return spring 22 and two protective sheets 21 for blocking the two jacks 15, respectively. The two protective sheets 21 are fixedly connected to both ends of the return spring 22. A guide block 23 for abutting against the pin is provided on the protective sheet 21, and the guide block 23 has a guide inclined surface 231 for abutting against the bottom end of the pin.

[0034] Reference Figure 3 and Figure 4When the pin is inserted into the jack 15, the pin contacts the guide bevel 231, and under the action of force, the pin pushes the guide block 23 away, and the protective sheet 21 no longer blocks the jack 15, and the pin can be inserted into the connection hole 43. When the pin of the plug is pulled out, under the action of the return spring 22, the protective sheet 21 returns to the original position and blocks the jack 15 again. By providing the protective sheet 21, it is not easy for fingers and other limbs to touch the inside of the jack 15, which plays a certain protective role and can prevent dust to a certain extent.

[0035] Reference Figure 3 and Figure 4 The protective sheet 21 is provided with a positioning hole 221 corresponding to the jack 15. The positioning hole 221 is located between the guide block 23 and the reset spring 22. The distance between the guide slope 231 and the protective sheet 21 gradually increases from the side close to the reset spring 22 to the other side. The reset spring 22 has an elastic tendency to bring the two protective sheets 21 closer to each other. In this embodiment, the reset spring 22 is a tension spring. When the pin is inserted into the jack 15, under the action of the guide slope 231, the protective sheet 21 moves in a direction away from the reset spring 22, the reset spring 22 is stretched, and then the pin is inserted into the positioning hole 221, and then inserted into the connecting hole 43. By setting the positioning hole 221, the position of the protective sheet 21 can be positioned.

[0036] Reference Figure 1 and Figure 4 A clamping portion 24 is provided on one end of the protective sheet 21 extending away from the reset spring 22, and a rotating rod 17 is provided on the shell 1. An elastic sheet 3 for abutting against the outer wall of the plug is provided on the shell 1, and the elastic sheet 3 includes an abutting portion 31 for abutting against the outer wall of the plug and a force-bearing portion 32. A clearance opening 16 for the elastic sheet 3 to rotate through is provided on the groove wall of the socket groove 14. A rotating rod 17 is provided at the clearance opening 16 of the upper shell 11, and the elastic sheet 3 is rotatably sleeved on the rotating rod 17, and the rotating rod 17 is located between the abutting portion 31 and the force-bearing portion 32. The end of the clamping portion 24 is used to abut against the force-bearing portion 32. When the pin is inserted into the socket 15 and abuts against the guide block 23, the two protective sheets 21 move away from each other, the pressing portion 24 abuts and pushes the force-bearing portion 32 to rotate, so that the elastic sheet 3 rotates around the rotating rod 17, so that the abutting portion 31 can better abut against the outer wall of the plug, thereby making the combination of the plug and the socket more secure and the plug is not easy to fall off the socket.

[0037] Reference Figure 3 and Figure 4 The housing 1 has a through hole 18 for the pressing part 24 to slide through, so as to guide the sliding movement of the pressing part 24. A guide piece 33 is bent at one end of the abutting part 31 away from the force-bearing part 32 to guide the insertion of the plug.

[0038] Reference Figure 5 An elastic extrusion sheet 44 is provided on the hole wall of the connecting hole 43. When the pin of the plug is inserted into the connecting hole 43, the elastic extrusion sheet 44 is deformed and pressed against the outer wall of the pin, thereby improving the stability of the electrical connection between the plug and the socket.

[0039] The implementation principle of an anti-electric shock switch socket in the embodiment of the present application is as follows: when the pin of the plug is inserted into the socket 15, under the guidance of the guide slope 231, the pin is inserted into the positioning hole 221 and the connecting hole 43 in sequence. At this time, the two protective sheets 21 move away from each other, the reset spring 22 is extended, the pressing part 24 abuts against the force-bearing part 32 of the elastic sheet 3, and the elastic sheet 3 rotates to a certain extent, so that the elastic sheet 3 can better abut against the outer wall of the plug, making it difficult for the plug to fall off. When the plug is pulled out of the socket, the reset spring 22 contracts, so that the two protective sheets 21 move closer to each other, and the two protective sheets 21 are blocked on the socket 15 again.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
