Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a clamping type sliding 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 clamping sliding structure, aiming to solve the problems that the existing plug is prone to generate electric sparks when inserted into the socket, the plug pins are prone to ablation, which shortens the service life and reduces the safety of use.

[0005] To achieve the above-mentioned purpose, the utility model provides a clamping sliding structure, which is arranged in a socket and corresponding to the wiring terminals. A metal conductive strip connected to the wiring terminals is arranged in the socket, including a socket, a clamping structure for abutting against the pins of a plug is formed on the socket, and a slot for inserting the pins is formed on the clamping structure. The socket is movably installed in the socket by an elastic member, and the socket is inserted into and contacts the socket by the pins to move relative to the socket and be conductively connected to the metal conductive strip.

[0006] Preferably, a limiting groove for installing the socket sleeve is formed in the socket. One end of the metal guide bar extends into the bottom of the limiting groove and is detachably provided with a fixed contact. A movable contact for abutting against the fixed contact is detachably installed on the bottom surface of the socket sleeve.

[0007] Preferably, a guiding groove is formed in one side wall of the limiting groove along the direction away from the metal guide bar. A protrusion for sliding contact and cooperation with the guiding groove is formed on the socket sleeve.

[0008] Preferably, an insertion cavity for accommodating the pin is formed in the socket sleeve. The clamping structure includes two clamping portions which are respectively formed on both sides of the socket sleeve, and the two clamping portions respectively extend towards the center of the insertion cavity and are bent to form the insertion slot. The width of one end of the insertion slot is smaller than the thickness of the pin.

[0009] Preferably, the tops of the two clamping portions are respectively bent away from the insertion slot.

[0010] Preferably, notches are respectively formed at the bent portions of the two clamping portions, and lugs are respectively formed at the two notches. The two lugs respectively extend and are bent away from the clamping portions, and elastic members are respectively and fixedly installed on the bottom surfaces of the two lugs.

[0011] Preferably, the clamping structure further includes two limiting plates which are respectively formed at both ends of the insertion slot, and the two limiting plates respectively extend towards the insertion slot. The distance between the two limiting plates is smaller than the width of the pin.

[0012] Preferably, avoidance grooves are respectively formed on both sides of the two clamping portions, and the two limiting plates respectively extend towards the insertion slot and are bent to form limiting portions for extending into the avoidance grooves.

[0013] Beneficial effects:

[0014] 1. In a clamping and sliding structure of the present utility model, the pin can be firmly clamped by the clamping mechanism, thereby preventing the pin from loosening or falling off after being inserted into the socket sleeve, reducing electrical faults caused by poor contact, and effectively improving the connection stability between the plug and the socket.

[0015] 2. In a clamping and sliding structure of the present utility model, the conductive connection between the plug and the socket can be achieved only when the socket sleeve and the metal guide bar complete secondary power connection. When the plug and the socket are conductively connected, electric sparks are generated between the socket sleeve and the metal guide bar. Thus, the phenomenon that the pin is ablated due to electric sparks can be avoided, which not only prolongs the service life of the plug, but also improves the use safety of the socket.

[0016] 3. When the plug is not inserted into the socket, the socket sleeve is always in a state of being disengaged from the metal guide bar under the action of the elastic member, that is, at this time, the socket sleeve and the metal guide bar have not completed the secondary power connection, so the socket sleeve is in a non - energized state, which can play a role in power - off protection, effectively preventing electric shock accidents caused by children's fingers or other foreign objects accidentally entering the socket, and making the use safer and more reliable.

[0030] Embodiment 1:

[0031] The present utility model provides a clamping and sliding structure.

[0032] In an embodiment of the present utility model, a clamping and sliding structure is provided in the socket 100 and arranged corresponding to the terminal. A metal guide bar 1 connected to the terminal is provided in the socket 100. The structure includes a socket sleeve 2. A clamping structure for abutting against the pin of the plug is formed on the socket sleeve 2. An insertion slot 3 for the pin to be inserted is formed on the clamping structure. The socket sleeve 2 is installed in the socket 100 in a limited and movable manner through an elastic member 4. And the socket sleeve 2 is electrically connected to the metal guide bar 1 by the pin being inserted into and contacting the socket sleeve 2 to move relative to the socket 100.

[0033] It should be noted that terminals are usually provided in the socket 100. The terminal is a key component connecting the wire and the socket 100, responsible for fixing wires such as "live wire", "neutral wire", and "ground wire" 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 terminal, electrical energy can be transmitted from the power source to the socket 100 and further transmitted to the connected electrical equipment, thus realizing the supply and distribution of electrical energy.

[0034] Specifically, as Figures 1 to 5 shown, in a clamping and sliding structure of the present utility model, since a clamping structure is formed on the socket sleeve 2 and an insertion slot 3 for the pin to be inserted is formed on the clamping structure, the pin of the plug can be inserted into the socket sleeve 2 through the insertion slot 3, and the pin can be firmly clamped by the clamping mechanism, thereby preventing the pin from loosening or falling off after being inserted into the socket sleeve 2, reducing electrical faults caused by poor contact, and effectively improving the connection stability between the plug and the socket 100. At the same time, when the pin is inserted into the socket sleeve 2, the pin pushes the socket sleeve 2 to move and compresses the elastic member 4 at this time, so that the socket sleeve 2 abuts against the metal guide bar 1, thereby completing the conduction of the circuit. The structural design is simple and reasonable.

[0035] Furthermore, during the process of inserting the plug, the pin of the plug is inserted into the socket sleeve 2 through the insertion slot 3. At this time, the clamping structure can abut against the pin, so that the socket sleeve 2 can transmit electrical energy to the pin, that is, realizing the first power connection between the socket sleeve 2 and the pin. At the same time, as the plug continues to be inserted deeply, the front end of the pin abuts against the socket sleeve 2 and pushes the socket sleeve 2 to move until it contacts the metal guide bar 1, thereby realizing the second power connection between the socket sleeve 2 and the metal guide bar 1. Obviously, in a clamping and sliding structure of the present utility model, only when the second power connection between the socket sleeve 2 and the metal guide bar 1 is completed can the conductive connection between the plug and the socket 100 be realized. And when the plug and the socket 100 are conductively connected, the electric spark is generated between the socket sleeve 2 and the metal guide bar 1. Thus, it can avoid the ablation phenomenon of the pin due to the electric spark, not only effectively extending the service life of the plug, but also improving the use safety of the socket 100.

[0036] Understandably, since the socket sleeve 2 is installed in the socket 100 in a limited and movable manner through the elastic member 4, the elastic member 4 can be selected as a spring in the prior art. The spring has the characteristics of being structurally compact, easy to obtain materials, and having a large elastic restoring force. Thus, when the plug is not inserted into the socket 100, the socket sleeve 2 is always in a state of being disengaged from the metal guide bar 1 under the action of the elastic member 4, that is, at this time, the socket sleeve 2 and the metal guide bar 1 have not completed secondary electrical connection, so the socket sleeve 2 is in a non-powered state, which can play a role in power-off protection, effectively preventing children's fingers or other foreign objects from entering the socket 100 by mistake and causing electric shock accidents, making the use safer and more reliable.

[0037] In one embodiment, a limiting groove 5 for installing the socket sleeve 2 is provided in the socket 100. One end of the metal guide bar 1 extends into the bottom of the limiting groove 5 and is detachably provided with a fixed contact 6, and a movable contact 7 for abutting against the fixed contact 6 is detachably installed on the bottom surface of the socket sleeve 2. Specifically, as Figures 1 to 3 shown, the shape of the limiting groove 5 should match the outer shape of the socket sleeve 2 to ensure that the socket sleeve 2 can be stably installed in the socket 100, and an appropriate gap should be left in the size of the limiting groove 5 so that the socket sleeve 2 can slide smoothly when pushed by the plug pin, and at the same time, it will not shake or shift. The structural design is simple and reasonable. Further, the metal guide bar 1 can be installed in the socket 100 and conductively connected to the wiring terminal by bolts, buckles or other detachable fixing methods, so as to facilitate maintenance or replacement. Understandably, since the fixed contact 6 and the movable contact 7 are respectively detachably installed on the bottom surfaces of the metal guide bar 1 and the socket sleeve 2, when the plug is inserted, the socket sleeve 2 moves under the action of the plug pin so that the movable contact 7 can tightly abut against the fixed contact 6 to form a stable conductive channel, thereby reducing the contact resistance, improving the conductive efficiency, and reducing the heat and energy consumption generated due to poor contact; at the same time, the detachable installation method of the movable contact 7 and the fixed contact 6 can be adopted as threaded connection or pin insertion, etc., so as to facilitate the disassembly and replacement of the fixed contact 6 and the movable contact 7, reducing the maintenance cost.

[0038] In one embodiment, as Figures 1 to 3 shown, a guiding groove 8 is provided on one side wall of the limiting groove 5 along the direction away from the metal guide bar 1, and a protrusion 9 for sliding contact and cooperation with the guiding groove 8 is formed on the socket sleeve 2. Specifically, the sliding contact and cooperation between the guiding groove 8 and the protrusion 9 can play a guiding role for the sliding of the socket sleeve 2, which can not only improve the stability and smoothness of the sliding of the socket sleeve 2, but also provide a better user experience, so that the user can feel a more fluent and stable hand feeling when plugging and unplugging the plug, reducing the inconvenience and trouble caused by difficult plugging and unplugging or unstable connection.

[0039] In one embodiment, as Figure 1 、 Figure 4 and Figure 5As shown, an insertion cavity for accommodating the pin is formed inside the socket sleeve 2. The clamping structure includes two clamping parts 10 which are respectively formed on both sides of the socket sleeve 2. The two clamping parts 10 respectively extend towards the center of the insertion cavity and bend to form an insertion slot 3. The width of one end of the insertion slot 3 is smaller than the thickness of the pin. Specifically, when the pin is inserted into the socket sleeve 2, since an insertion cavity for accommodating the pin is formed inside the socket sleeve 2, the contact area between the pin and the socket sleeve 2 can be reduced, preventing the pin of the plug from being worn by the socket sleeve 2 during repeated insertion and extraction, and prolonging the service life of the plug. Further, since the two clamping parts in the clamping structure are respectively formed on both sides of the socket sleeve 2, and the two clamping parts 10 respectively extend towards the center of the insertion cavity and bend, an insertion slot 3 can be formed, so that the two clamping parts 10 can automatically clamp the pin when the pin is inserted, thereby achieving a stable electrical connection. It can be understood that since the width of one end of the insertion slot 3 is smaller than the thickness of the pin, the pin can be squeezed by the clamping part 10 during the insertion process and smoothly enter the insertion cavity, improving the clamping stability of the pin; at the same time, the other end of the insertion slot 3 should maintain a sufficient width so that the pin can smoothly enter the socket sleeve 2 through the insertion slot 3, and the structural design is simple and reasonable.

[0040] In one embodiment, specifically, as Figure 1 , Figure 4 and Figure 5 shown, the tops of the two clamping parts 10 are respectively bent away from the insertion slot 3, so as to play a guiding role for the pin when the pin is inserted into the socket sleeve 2, thereby improving the smoothness of inserting the plug and enhancing the user experience.

[0041] In one embodiment, notches 11 are respectively formed at the bending parts of the two clamping parts 10. Lugs 12 are respectively formed at the two notches 11. The two lugs 12 respectively extend and bend away from the clamping part 10, and elastic members 4 are respectively fixedly installed on the bottom surfaces of the two lugs 12. Specifically, as Figures 1 to 5 shown, by respectively forming notches 11 at the bending parts of the two clamping parts 10, the material thickness of the clamping part 10 at this position can be reduced, allowing the clamping part 10 to be more easily bent and deformed when subjected to an external force, which is easy to produce and manufacture. Further, by respectively fixedly installing elastic members 4 on the bottom surfaces of the two lugs 12, it can be ensured that when no plug is inserted into the socket 100 under the action of the two elastic members 4, the socket sleeve 2 is always in a state of being disengaged from the metal guide sleeve, and the socket sleeve 2 is more evenly stressed, improving the smoothness and stability of the socket 100 during rebound and sliding.

[0042] In one embodiment, as Figure 1 , Figure 4 and Figure 5As shown, the clamping structure further includes two limiting plates 13, which are respectively formed at both ends of the insertion slot 3, and the two limiting plates 13 respectively extend towards the insertion slot 3. The distance between the two limiting plates 13 is less than the width of the pin, so as to be able to abut and limit both sides of the pin along its width direction, and expand the contact area between the pin and the socket 2. Furthermore, not only the connection stability between the plug and the socket 100 is improved, preventing the plug from loosening, but also the stability of the electrical connection between the plug and the socket 100 can be effectively ensured.

[0043] In another embodiment, as Figure 1 , Figure 4 and Figure 5 shown, avoidance grooves 14 are respectively formed on both sides of the two clamping portions 10, and the two limiting plates 13 respectively extend towards the insertion slot 3 and are bent to form limiting portions 15 for extending into the avoidance grooves 14. Specifically, by extending the two limiting portions 15 into the avoidance grooves 14, the two limiting portions 15 can clamp and limit both sides of the pin along its width direction, and the two limiting portions 15 are in closer contact with the pin, further improving the stability of the electrical connection between the plug and the socket 100.

[0044] The above are only the preferred embodiments of the present application and are not used 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 in the protection scope of the present application.
