[0002] Socket, also known as power socket, switch socket. A socket refers to a seat into which one or more circuit wiring can be inserted, through which various wiring can be inserted. A socket is usually provided in the socket, and its main function is to provide a current path to ensure stable and safe conduction when the plug is inserted. In the prior art, a socket socket is proposed, which includes a first contact piece and a second contact piece, the first contact piece is connected to the socket body, and the second contact piece is connected to the socket body through a flat straight edge structure. However, after the socket has been plugged and unplugged for 5,000 times as stipulated by the national standard, the flat straight edge structure cannot provide enough elastic force to the second contact piece, resulting in deformation of the second contact piece, and the poor contact between the socket and the plug pin causes the socket to be unable to continue to be used, thereby failing to guarantee the service life of the socket.

[0003] At the same time, 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 a physical point of view, electric sparks will inevitably be generated at the moment of power connection, and 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 plug sleeve structure, aiming to solve the problem that the existing plug and the plug sleeve are easily corroded and burned due to electric sparks, which not only shortens the service life but also reduces the safety of use.

[0005] To achieve the above-mentioned purpose, the utility model provides a socket structure, which is arranged in a socket and corresponds to a wiring terminal, and includes a socket body, a slot for inserting a plug pin of a plug is formed on the socket body, and a movable end is formed on the socket body. The movable end is inserted into and contacts the socket body through the plug pin to move relative to the socket and be conductively connected to the wiring terminal.

[0006] Preferably, a movable contact is detachably mounted on the movable end, and a fixed contact for abutting against the movable contact is detachably mounted on the connecting terminal.

[0007] Preferably, a slot for accommodating the pin is formed in the socket body, and ears are formed on both sides of the socket body, and the two ears are bent toward the center of the slot to form the gap.

[0008] Preferably, the tops of the two lugs are bent away from the gap respectively.

[0009] Preferably, the width of one end of the gap is smaller than that of the other end.

[0010] Preferably, the socket body includes a fixed part and a movable part, and the fixed part and the movable part extend towards the socket panel respectively and are bent away from the gap to form limiting parts for abutting against the plug pins respectively.

[0011] Preferably, the distance between the two limiting parts is smaller than the length of the plug pin.

[0012] Preferably, grooves for the limiting parts to extend into are formed on one side of the two lugs away from the fixed part.

[0013] Preferably, notches are formed at the bending parts of the two lugs respectively.

[0014] Preferably, the top end of the movable part extends and bends away from the fixed part to form the movable end.

[0015] Beneficial effects:

[0016] 1.

[0033] Embodiment 1:

[0034] The present utility model provides a socket structure.

[0035] In an embodiment of the present utility model, a socket structure is provided inside a socket and arranged corresponding to a wiring terminal 1. The socket structure includes a socket body 2, a gap 3 is formed on the socket body 2 for the insertion pin of a plug to insert into, and a movable end 4 is formed on the socket body 2. The movable end 4 is inserted and contacts the socket body 2 by the insertion pin to move relative to the socket and conductively connect with the wiring terminal 1.

[0036] It should be noted that in the prior art, a wiring terminal 1 is usually provided inside a socket. The wiring terminal 1 is a key component for connecting wires and the socket, responsible for fixing wires such as "live wire", "neutral wire", and "ground wire" behind the socket to ensure that the wires can be reliably and well connected to the current-carrying components of the socket. Through the wiring terminal 1, electrical energy can be transmitted from the power source to the socket and further transmitted to the connected electrical equipment, thereby realizing the supply and distribution of electrical energy.

[0037] Specifically, as Figures 1 to 5 shown, since a socket structure of the present utility model is provided inside a socket and arranged corresponding to the wiring terminal 1, and a gap 3 is formed on the socket body, and the gap 3 is correspondingly arranged with the jack on the socket panel, so that the insertion pin of the plug can be inserted into the socket body 2 through the gap 3. Further, since a movable end 4 is formed on the socket body 2, after the insertion pin of the plug is inserted into the socket body 2, the insertion pin abuts against the movable end 4 and pushes the movable end 4 to move relative to the socket, and then the movable end 4 contacts the wiring terminal 1 to achieve conductive connection. The structural design is simple and reasonable.

[0038] It can be understood that when the socket structure of the present utility model is actually used, by arranging it corresponding to the wiring terminal 1 inside the socket, that is, one of the present utility models is respectively arranged corresponding to the "live wire wiring terminal", "neutral wire wiring terminal", and "ground wire wiring terminal" inside the socket, so that the present utility model can be applicable to different styles and types of sockets, with high flexibility and wide application range. Further, when the present utility model corresponding to a certain wiring terminal 1 is damaged, the maintenance personnel can directly replace the present utility model corresponding to the wiring terminal 1 to repair the socket, which is not only simple and convenient to operate, but also saves the maintenance cost of the socket.

[0039] In addition, during the process of inserting the plug pins into the socket body 2, since the plug pins are in contact with the socket body 2, the socket body 2 can transmit electric energy to the plug pins, that is, the first electrical connection between the socket body 2 and the plug pins is realized; at the same time, the movable end 4 of the socket body 2 can be pushed by the plug pins and made to contact the terminal 1, thereby realizing the second electrical connection between the terminal 1 and the socket body 2. Obviously, the socket can only supply electric energy to the plug when the movable end 4 is in contact with the terminal 1, and electric sparks are generated at the movable end 4 and the terminal 1, which can protect the plug pins and the present invention, effectively preventing the plug pins and the present invention from being ablated. This not only extends the service life of the plug and the present invention, but also improves the use safety, and realizes a service life far higher than the national standard requirement of 5,000 times for the socket plug and unplug operations. The actual use results show that the socket provided with the present invention can be plugged and unplugged more than 5,000 times, reaching 30,000 times or more. And when a socket corresponding to a certain terminal 1 is damaged, it can be directly disassembled, assembled and replaced individually to further improve the service life of the socket, with high practicability.

[0040] It should be noted that since the function of the plug pin for the ground wire is to connect the metal shell of the electrical appliance to the ground to form a ground protection, in actual application of the present invention, the present invention can be selectively not arranged on the ground wire terminal 1 according to the usage situation, so as to save the production and manufacturing cost of the socket.

[0041] In an embodiment, a movable contact 5 is detachably installed on the movable end 4, and a fixed contact 6 for abutting against the movable contact 5 is detachably installed on the terminal 1. As Figures 1 to 3 shown, it can be understood that the distance between the movable end 4 and the terminal 1 can be reduced by the movable contact 5 and the fixed contact 6, and when the plug is inserted, the movable contact 5 and the fixed contact 6 can tightly abut against each other to form a stable conductive path, thereby reducing the contact resistance, improving the conductive efficiency, and reducing the heat and energy consumption generated due to poor contact. Further, the movable contact 5 and the fixed contact 6 are both designed to be detachable, making the maintenance and replacement of the socket simpler and faster. If the movable contact 5 or the fixed contact 6 is worn or damaged due to long-term use, the maintenance personnel can replace the contact individually without replacing the entire socket or the terminal 1, thereby reducing the maintenance cost and time.

[0042] It should be noted that the movable contact 5 and the fixed contact 6 can also be integrally formed with the socket body 2 and the terminal 1 respectively, which is convenient for production and manufacturing and omits the assembly process. In addition, the movable contact 5 and the fixed contact 6 can be selected as silver points in the prior art. Silver is one of the materials with the best electrical conductivity in metals, and its resistivity is extremely low. Therefore, silver contacts can reduce energy loss during current transmission and improve the transmission efficiency of electrical connections.

[0043] In one embodiment, a slot 7 for accommodating pins is formed in the socket body 2. Ears 8 are respectively formed on both sides of the socket body 2, and the two ears 8 are bent towards the center of the slot 7 to form a gap 3. Specifically, as Figure 2 、 Figure 3 and Figure 5 shown, the slot 7 helps to reduce the friction and wear between the pins and the socket body 2, thereby improving the connection stability and durability. Further, the ears 8 on both sides of the socket body 2 can not only provide guidance for the insertion of the pins, but also play a role in laterally supporting the socket body 2, thereby enhancing the structural strength of the socket body 2. And the two ears 8 are bent towards the center of the slot 7 respectively, whereby a gap 3 for the pins to insert can be formed, and the structural design is simple and reasonable. It can be understood that the bent ears 8 usually have a certain elasticity, that is, when the pins are inserted, the two ears 8 will slightly open for the pins to insert into the slot 7 through the gap 3, and at the same time, the two ears 8 can rebound to clamp the pins, thereby improving the tightness and stability of the connection between the pins and the socket body 2.

[0044] In one embodiment, specifically, as Figure 3 and Figure 5 shown, the tops of the two ears 8 are bent away from the gap 3 respectively, so that it can not only guide the pins to smoothly insert into the slot 7 through the gap 3, but also provide a certain resistance through the bent parts of the ears 8, thereby helping the user to pull out the plug more stably and avoiding accidental detachment or damage.

[0045] In one embodiment, as Figure 2 and Figure 5 shown, the width of one end of the gap 3 is smaller than that of the other end. It can be understood that since the width of one end of the gap 3 is smaller, the pins will be subjected to a certain extrusion and clamping force when passing through this area, thereby enhancing the connection tightness between the pins and the socket body 2 and helping to reduce problems such as poor contact, increased resistance and heating.

[0046] In one embodiment, specifically, as Figure 2 、 Figure 3 and Figure 5 shown, the socket body 2 includes a fixed part 9 and a movable part 10. The fixed part 9 and the movable part 10 respectively extend towards the socket panel and are bent away from the gap 3 to respectively form a limiting part 11 for abutting against the pins, so that the two limiting parts 11 can abut against and limit the pins, which not only helps to prevent the pins from shaking or falling off in the slot 7, but also ensures good contact between the pins and the socket, and avoids electrical faults or safety hazards caused by poor contact or short circuit.

[0047] In one embodiment, the distance between the two limiting parts 11 is less than the length of the pins. AsFigure 2 and Figure 3 As shown, it can be understood that since the two limiting parts 11 clamp the pin from both sides and the distance therebetween is less than the length of the pin, the stable insertion of the pin into the slot 7 can be ensured, which not only reduces the risk of the pin loosening or falling off due to external forces (such as vibration and shaking), but also improves the reliability of the electrical connection. Further, when the pin is inserted into the slot 7, since the distance between the two limiting parts 11 is less than the length of the pin, the movable part 10 can move away from the fixed part 9 under the push of the pin, and thus the movable contact 5 on the movable part 10 can contact the fixed contact 6 on the terminal 1 to achieve electrical connection, and the structural design is simple and reasonable.

[0048] In another embodiment, on one side of the two lugs 8 away from the fixed part 9, grooves are formed for the limiting parts 11 to extend into. It can be understood that when the pin is not inserted into the slot 7, the limiting parts 11 formed on the movable part 10 extend into the grooves, and at this time, the movable contact 5 on the movable part 10 does not contact the fixed contact 6 on the terminal 1. Further, when the pin is inserted into the slot 7, the pin abuts against the limiting parts 11 on the movable part 10 and pushes the movable part 10 to move away from the fixed part 9, so that the movable contact 5 on the movable part 10 can contact the fixed contact 6 on the terminal 1 to achieve electrical connection. Since the limiting parts 11 formed on the movable part 10 extend into the grooves when the pin is not inserted into the slot 7, the limiting parts 11 abut against the pin more tightly, thereby reducing the problem of poor contact between the pin and the limiting parts 11.

[0049] In one embodiment, specifically, as Figures 3 to 5 shown, notches 12 are respectively formed at the bending parts of the two lugs 8, so as to facilitate the two lugs 8 to bend towards the center of the slot 7 to form a gap 3, reduce the stress concentration when the two lugs 8 are bent, be easy to manufacture, and the structural design is simple and reasonable.

[0050] In one embodiment, as Figures 1 to 3 shown, the top end of the movable part 10 extends and bends away from the fixed part 9 to form a movable end 4, so as to further reduce the gap between the terminal 1 and the socket body 2, and further improve the connection tightness after the movable contact 5 abuts against the fixed contact 6, and ensure the stable transmission of the secondary power connection.

[0051] 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.
