Description
Technical Field
[0001] The utility model relates to the field of electrical technology, in particular to a gear linkage structure. Background Art
[0002] With the rapid development of science and technology and the improvement of people's living standards, sockets, as indispensable electrical accessories in daily life, are receiving more and more attention for their safety, convenience and intelligence. The main way to connect the power of traditional sockets is that the plug is in direct contact with the metal of the socket. Although this exposed connection method is simple and direct, it has many safety hazards, such as leakage, short circuit, electric sparks, etc., especially when used in humid, wading or dusty environments, the risks are more significant; at the same time, during the connection process of traditional sockets, due to the direct contact between the metal parts of the plug and the socket, electric sparks are often generated at the moment of power-on. This kind of electric spark may not be conspicuous in ordinary environments, but under certain conditions, such as flour mills, wood processing workshops and other dusty places, electric sparks can easily become ignition sources for dust explosions, posing safety hazards.
[0003] The sockets in the prior art are basically connected by direct connection, that is, as long as the plug is inserted into the socket, the pins of the plug contact the socket in the socket to realize the conduction of the circuit. From the perspective of physics, electric sparks will inevitably be generated at the moment of power connection, and the electric sparks will corrode the plug and the socket. Long-term electrical corrosion will cause the plug and the socket to burn, thereby shortening the service life of the plug and the socket, and easily causing poor contact and loose connection between the plug and the socket, which will cause the temperature to rise and cause electrical fires, reducing the safety of use. Utility Model Content
[0004] The main purpose of the utility model is to provide a gear linkage structure, aiming to solve the problem that the existing socket has low safety in use and the plug pins are prone to ablation and shorten the service life.
[0005] To achieve the above-mentioned purpose, the utility model provides a gear linkage structure, which is arranged in a socket for conductive connection between a plug and a socket, wherein a metal conductive strip detachably connected to a wiring terminal is arranged in the socket, comprising a socket, a transmission assembly and a conduction block, wherein a mounting groove for mounting the socket and the transmission assembly is provided in the socket, a slot for inserting a pin is formed on the socket, the socket is movably mounted in the socket by an elastic member, the socket is connected to the conduction block by a wire, and the socket drives the conduction block to move through the transmission assembly to abut against the metal conductive strip.
[0006] Preferably, one end of the metal conducting bar extends to the notch of the installation groove and bends towards the direction of the socket to form a conductive end for abutting against the conducting block. The transmission assembly includes a gear, a driving rack and a driven rack. The gear is rotatably installed in the installation groove through a rotating shaft. The driving rack and the driven rack are respectively detachably installed on the socket and the conducting block and are both meshed with the gear.
[0007] Preferably, a positioning notch for the metal conducting bar to extend into is formed at one end of the installation groove. A boss is formed at the bottom of the installation groove corresponding to the positioning notch. One side of the boss facing the positioning notch is used for abutting against the metal conducting bar. And a first guiding groove is formed on the side of the boss away from the positioning notch. A first guide rail for sliding contact and cooperation with the first guiding groove is formed on the conducting block.
[0008] Preferably, a fixed contact is detachably installed on the conductive end. A movable contact for abutting against the fixed contact is detachably installed on the side of the conducting block facing the conductive end.
[0009] Preferably, limiting protrusions are respectively formed corresponding to the bottom of the installation groove and the bottom surface of the socket. The elastic member is a spring. Two ends of the spring are respectively sleeved on the outer walls of the two limiting protrusions.
[0010] Preferably, a second guiding groove is formed on one side wall of the installation groove. A second guide rail for sliding contact and cooperation with the second guiding groove is formed on the socket.
[0011] Preferably, a groove for accommodating the wire is formed at the bottom of the installation groove corresponding to the position of the transmission assembly.
[0012] Beneficial effects:
[0013] 1. During the use of a gear linkage structure of the present utility model, if the plug is not inserted in place and the conducting block does not abut against the metal conducting bar, at this time, the socket cannot transmit electric energy to the pin, thereby effectively avoiding electric shock accidents caused by the plug not being inserted in place, reducing potential safety hazards, and greatly improving the use safety of the socket.
[0014] 2. Since secondary electrical connection is formed between the conducting block and the metal conducting bar, the electric sparks generated when the plug and the socket are conductively connected exist at the conducting block and the metal conducting bar, thereby being able to protect the pin and effectively preventing the pin from being ablated due to electric sparks, and prolonging the service life of the plug.
[0015] 3. When the plug is unplugged, the socket sleeve can automatically reset to the initial position under the action of the elastic member, and the conduction block can be driven by the transmission component to synchronously reset and separate the conduction block from the metal guide bar, thereby automatically cutting off the secondary power connection between the conduction block and the metal guide bar in the socket. That is, when the plug is not inserted, the socket sleeve is in a power-off state. This automatic reset power-off function can be used in conjunction with the protection door at the socket jack to prevent children's fingers or other foreign objects from reaching into the socket and causing electric shock accidents, further improving the safety of using the socket.

[0028] Embodiment 1:
[0029] The present utility model provides a gear linkage structure.
[0030] In an embodiment of the present utility model, a gear 8 linkage structure is provided in a socket 100 for electrically connecting a plug and the socket 100. A metal guide bar 1 detachably connected to a terminal is provided in the socket 100, and includes a socket sleeve 2, a transmission assembly, and a conduction block 3. An installation groove 4 for installing the socket sleeve 2 and the transmission assembly is formed in the socket 100. A slot for inserting a plug pin is formed on the socket sleeve 2. The socket sleeve 2 is installed in the socket 100 in a limited and movable manner through an elastic member 5. The socket sleeve 2 is electrically connected to the conduction block 3 through a wire 6, and the socket sleeve 2 drives the conduction block 3 to move to abut against the metal guide bar 1 through the transmission assembly.
[0031] Specifically, as Figures 1 to 4 shown, in a gear 8 linkage structure of the present utility model, since the installation groove 4 is formed in the socket 100, the socket sleeve 2 and the transmission assembly can be installed in the installation groove 4, that is, the installation groove 4 can provide a stable installation environment to ensure that each component can be correctly installed and work together. Further, since the slot is formed on the socket sleeve 2, the socket sleeve 2 is installed in the socket 100 in a limited and movable manner through the elastic member 5, and the socket sleeve 2 is connected to the conduction block 3 through the wire 6. When the plug is inserted into the socket 100, the plug pin of the plug can be inserted into the socket sleeve 2 through the slot until the end of the plug pin abuts against the socket sleeve 2. As the plug pin continuously penetrates, at this time, the plug pin can drive the socket sleeve 2 to move, and at the same time, the elastic member 5 is gradually compressed. During this process, the conduction block 3 can be driven to move synchronously through the transmission assembly, so that the conduction block 3 abuts against the metal guide bar 1, thereby completing the electrical connection between the plug and the socket 100. The structural design is simple and reasonable.
[0032] Understandably, when the pin of the plug contacts the socket 2, since the socket 2 is connected to the conduction block 3 through the wire 6, at this time, the pin, the socket 2 and the conduction block 3 complete a connection; as the pin continuously penetrates deeper, at this time, the socket 2 moves away from the panel of the socket 100 under the push of the pin and compresses the elastic member 5, and at the same time, the conduction block 3 can be synchronously driven to move through the transmission assembly and make the conduction block 3 contact the metal guide bar 1, thereby completing the secondary connection between the conduction block 3 and the metal guide bar 1. Obviously, during the process of inserting the plug, the plug can only achieve the conductive connection between the plug and the socket 100 after being completely inserted into the socket 100, that is, after the conduction block 3 and the metal guide bar 1 complete the secondary connection. If the plug is not inserted in place and the conduction block 3 does not contact the metal guide bar 1, at this time, the socket 100 cannot transmit electrical energy to the pin, thereby effectively avoiding electric shock accidents caused by the plug not being inserted in place, reducing potential safety hazards, and greatly improving the use safety of the socket 100; at the same time, since there is a secondary connection between the conduction block 3 and the metal guide bar 1, the electric spark generated when the plug is conductively connected to the socket 100 exists at the conduction block 3 and the metal guide bar 1, thereby being able to protect the pin and effectively preventing the pin from being ablated due to the electric spark, and prolonging the service life of the plug.
[0033] In addition, when the plug is pulled out, the socket 2 can automatically reset to the initial position under the action of the elastic member 5, and the conduction block 3 can be driven by the transmission assembly to reset synchronously and separate the conduction block 3 from the metal guide bar 1, thereby automatically cutting off the secondary connection between the conduction block 3 and the metal guide bar 1 in the socket 100, that is, the socket 2 is in a power-off state when the plug is not inserted. This automatic reset power-off function can be used in conjunction with the protection door at the socket 100 jack to prevent children's fingers or other foreign objects from reaching into the socket 100 and causing electric shock accidents, further improving the use safety of the socket 100.
[0034] It should be noted that in the prior art, a wiring terminal is usually provided inside the socket 100. The wiring terminal is a key component for connecting the wire and the socket 100, and is responsible for fixing wires such as the "live wire", "neutral wire", and "ground wire" 6 behind the socket 100 to ensure that the wire can be reliably and well connected to the current-carrying member (metal guide bar 1) of the socket 100. Through the wiring terminal, electrical energy can be transmitted from the power source to the socket 100 and further transmitted to the connected electrical equipment, thereby realizing the supply and distribution of electrical energy.
[0035] In one embodiment, one end of the metal conducting bar 1 extends to the notch of the installation groove 4 and bends towards the socket 2 to form a conductive end 7 for abutting against the conduction block 3. The transmission assembly includes a gear 8, a driving rack 9 and a driven rack 10. The gear 8 is rotatably mounted in the installation groove 4 through a rotating shaft. The driving rack 9 and the driven rack 10 are respectively detachably mounted on the socket 2 and the conduction block 3 and are both engaged with the gear 8.
[0036] Specifically, as Figures 1 to 4 shown, since the metal conducting bar 1 is formed with a conductive end 7 for abutting against the conduction block 3, a closer and more stable contact can be formed between the conduction block 3 through the conductive end 7, thereby ensuring that the current can pass smoothly, so as to realize the secondary connection between the conduction block 3 and the metal conducting bar 1. The structural design is simple and reasonable. Further, since the gear 8 in the transmission assembly is rotatably mounted in the installation groove 4, and the driving rack 9 and the driven rack 10 are respectively detachably mounted on the socket 2 and the conduction block 3 and are both engaged with the gear 8, when the plug is inserted into the socket 2, the socket 2 and the driving gear 8 on the socket 2 both move away from the panel of the socket 100, so as to drive the gear 8 to rotate. At this time, the driven rack 10 moves towards the panel of the socket 100, and then can synchronously drive the conduction block 3 to move and make the conduction block 3 abut against the conductive end 7, thereby completing the secondary electrical connection between the conduction block 3 and the metal conducting bar 1, so that the socket 100 can transmit electric energy to the plug. The structural design is ingenious and reasonable. It can be understood that through the precise meshing of the gear 8 and the rack, the stable and accurate transmission between the socket 2 and the conduction block 3 is realized, and the stability and reliability of the conductive path are improved; and only when the plug is completely inserted and the conduction block 3 abuts against the metal conducting bar 1 can the conductive connection between the plug and the socket 100 be completed, effectively preventing the electric shock accident caused by the incomplete insertion of the plug.
[0037] In one embodiment, a positioning notch for the metal conducting bar 1 to extend into is formed at one end of the installation groove 4, and a convex platform 11 is formed at the bottom of the installation groove 4 corresponding to the positioning notch. One side of the convex platform 11 facing the positioning notch is used for abutting against the metal conducting bar 1, and a first guiding groove 12 is formed on the side of the convex platform 11 away from the positioning notch. A first guide rail 13 for sliding contact and cooperation with the first guiding groove 12 is formed on the conduction block 3. Specifically, as Figures 1 to 4 shown, the installation of the metal conducting bar 1 can be limited through the positioning notch, and a stable supporting surface can be provided for the metal conducting bar 1 through the convex platform 11, thereby ensuring the stability of the metal conducting bar 1 in the installation groove 4 and improving the stability and reliability of the conductive path. Further, since a first guiding groove 12 is formed on the side of the convex platform 11 away from the positioning notch, through the sliding contact and cooperation between the first guide rail 13 on the conduction block 3 and the first guiding groove 12, it can be ensured that when the socket 2 moves, the conduction block 3 moves synchronously along a preset path to closely abut against the conductive end 7 of the metal conducting bar 1. The structural design is simple and reasonable.
[0038] In one embodiment, a fixed contact 14 is detachably mounted on the conductive end 7, and a movable contact 15 for abutting against the fixed contact 14 is detachably mounted on one side of the conduction block 3 facing the conductive end 7. Specifically, as shown in Figure 1 and Figure 4 , the detachable mounting methods of the fixed contact 14 and the movable contact 15 can both adopt riveting or threaded connection, which is convenient for disassembly, replacement; at the same time, when the socket 100 is used for a long time, if the fixed contact 14 and the movable contact 15 are worn or damaged, the user can remove and replace the corresponding damaged fixed contact 14 or movable contact 15 without replacing the entire metal guide bar 1 or conduction block 3, reducing the maintenance cost. Further, the distance between the conduction block 3 and the conductive end 7 can be reduced through the fixed contact 14 and the movable contact 15, thereby reducing the generation of electric arcs, and the contact surfaces of the fixed contact 14 and the movable contact 15 are relatively flat, thereby improving the stability of the conductive connection between the conduction block 3 and the conductive end 7, and reducing problems such as increased resistance, heating, and even arcing caused by poor contact between the conduction block 3 and the conductive end 7.
[0039] In one embodiment, as shown in Figure 2 and Figure 4 , limiting protrusions 16 are respectively formed corresponding to the bottom of the installation groove 4 and the bottom surface of the socket 2. The elastic member 5 is a spring, and both ends of the spring are respectively sleeved on the outer walls of the two limiting protrusions 16. Specifically, the elastic member 5 can be selected as a spring in the prior art. The spring has the characteristics of compact structure, easy material selection, and large elastic restoring force. The elastic restoring force of the spring ensures that the socket 2 can accurately automatically reset to the initial position after the plug is pulled out, thereby ensuring the reliable disconnection of the circuit. Further, the two limiting protrusions 16 can limit both ends of the spring, thereby preventing the socket 2 from shaking and shifting during movement, and improving the stability of the socket 2 during movement.
[0040] In one embodiment, as shown in Figure 2 and Figure 4 , a second guiding groove 17 is formed on one side wall of the installation groove 4, and a second guiding rail 18 for sliding contact and cooperation with the second guiding groove 17 is formed on the socket 2. Specifically, the sliding contact and cooperation between the second guiding rail 18 and the second guiding groove 17 enables the socket 2 to move along a preset path, improving the smoothness of the socket 2 during movement.
[0041] In one embodiment, specifically, as shown in Figure 3 and Figure 4As shown, a groove 19 for accommodating a wire 6 is formed at the bottom of the installation groove 4 corresponding to the position of the transmission assembly, so as to prevent the wire 6 from being exposed outside the installation groove 4 and wound around the transmission assembly, which affects the movement of the conduction block 3, and ensure the stability and reliability of the electrical connection between the plug and the socket 100. In addition, during the actual installation of the present utility model, the wire 6 can be firmly installed in the groove 19 by means of bonding or the like, and the operation is simple and convenient.
[0042] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
