DETAILED DESCRIPTION

[0018] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0019] This embodiment provides a technical solution: a smart socket with interconnection control function, such as Figure 1-6 As shown, the socket in this embodiment has only two sockets and includes a housing, at least one plug-in mechanism 2, and an electrical circuit mechanism. The housing is assembled and fixed by screwing a bottom shell 11 and a cover 12 to facilitate subsequent maintenance or repair. At least one pair of sockets 13 is defined on the front (i.e., the side in use) of the housing. The plug-in mechanisms 2 are located within the housing. The number of plug-in mechanisms 2 and sockets 13 is the same, and the two are arranged in a corresponding manner. In this embodiment, there are three plug-in mechanisms 2, and the three plug-in mechanisms 2 are arranged in a straight line.

[0020] The three plug-in mechanisms 2 are all arranged inside the shell. The plug-in mechanism 2 includes a rectangular mounting frame 21 fixed inside the shell, which plays a role of single protection. A pair of fixed metal contact terminals 22 are installed on the shell inside the rectangular mounting frame 21. The pair of fixed metal contact terminals 22 are electrically connected to the external power supply through the electrical circuit mechanism to achieve power supply.

[0021] Two expandable connection components are installed inside the rectangular mounting frame 21 and a reset component is installed outside the rectangular mounting frame 21; the expandable connection component is used to electrically connect the plug pins with the fixed metal contact terminals 22 when the plug pins are inserted into the socket 13, thereby supplying power to the plug; the reset component is used to reset the two expandable connection components when the temperature inside the shell reaches a set value, so as to pop out the plug and cut off the power, thereby avoiding the risk of further spread of fire.

[0022] Furthermore, the expandable connection assembly includes two first mounting shafts rotatably mounted on the inner wall of the rectangular mounting frame 21, and a spiral spring (not shown in the figure) is installed between the first mounting shaft and the rectangular mounting frame 21. The inner end of the spiral spring is fixed to the first mounting shaft, and the outer end is fixed to the inner wall of the rectangular mounting frame 21. A power transmission roll 233 is wound around the two first mounting shafts. The power transmission roll 233 is formed by winding an elastic insulating material (such as rubber) around the first mounting shaft. A movable push block 231 is commonly installed at the ends of the two power transmission rolls 233, and the two movable push blocks 231 correspond to a pair of sockets 13 respectively, which can play a role in blocking dust. Two guide rollers 234 are installed inside the rectangular mounting frame 21. The two guide rollers 234 are respectively used to guide the power transmission roll 233 when it is pulled open. The movable push block 231 and the power transmission roll 233 are commonly provided with an electric contact structure for connecting the fixed metal contact terminal 22 and the pin of the plug.

[0023] When the pin of the plug is inserted into the socket 13, the pin of the plug pushes the movable push block 231 to move, and the movable metal contact terminal 232 will also move toward the side of the fixed metal contact terminal 22 until the movable metal contact terminal 232 is tightly fitted with the fixed metal contact terminal 22 to form an electrical connection. At the same time, the first mounting shaft will be pulled to rotate, and the spiral spring will deform and store force; when the pin of the plug is pulled out of the socket 13, the power transmission coil 233 will return to its original position due to the elastic force of the spiral spring.

[0024] Furthermore, the fixed metal contact terminal 22 and the movable metal contact terminal 232 are both elastic sheets with a circle. The fixed metal contact terminal 22 has a curved groove portion in the middle position on one side close to the movable metal contact terminal 232, and the movable metal contact terminal 232 has a curved protrusion portion in the middle position on one side close to the fixed metal contact terminal 22, and the curved groove portion is adapted to the curved protrusion portion. When the fixed metal contact terminal 22 and the movable metal contact terminal 232 are in contact, the elasticity of the fixed metal contact terminal 22 and the movable metal contact terminal 232 ensure the stability and contact area of ​​the connection between the two.

[0025] Furthermore, the rectangular installation frame 21 is provided with symmetrically arranged sliding grooves 25 , and the two ends of the movable push block 231 are slidably arranged in the two sliding grooves 25 respectively.

[0026] Furthermore, the electric contact structure includes a negative wire buried inside the movable push block 231 and the power transmission roll 233, and the negative wire is electrically connected to the movable metal contact terminal 232. A metal sheet 235 is provided on one side surface of the two power transmission rolls 233, and the metal sheet 235 is electrically connected to the negative wire. The negative wire and the metal sheet 235 are both made of metal strips and can be bent.

[0027] A contact assembly is provided inside the rectangular mounting frame 21. Each expandable connection assembly corresponds to two contact assemblies, and the two contact assemblies are respectively located on both sides of the slide slot 25. The contact assembly is used to squeeze the power transmission coil 233 toward the side of the plug pin to achieve contact and power supply between the metal sheet 235 and the plug pin. This method can increase the contact area between the plug pin and the metal sheet 235, as well as the reliability of the contact, which can reduce the risk of fire and improve safety performance.

[0028] Furthermore, the contact assembly includes a second mounting shaft fixed to the inside of the rectangular mounting frame 21, a bent flip block 241 is rotatably mounted on the second mounting shaft, and the second mounting shaft is connected to the bend of the bent flip block 241, the two folded edges of the bent flip block 241 are the flip portion and the push portion, and the side of the bent flip block 241 close to the power coil 233 is equipped with an extrusion push block 243, specifically, the extrusion push block 243 is installed on the flip portion of the bent flip block 241, and the extrusion push block 243 is an insulating The rectangular mounting frame 21 is made of a body material to improve safety performance. The bent flip block 241 and the second mounting shaft are jointly installed with a torsion spring 242. The torsion spring 242 gives the extrusion push block 243 a force to flip to the opposite side of the fixed metal contact terminal 22. The inner wall of the rectangular mounting frame 21 is fixed with a limiting block 244, which limits the bent flip block 241. When it is not subjected to other forces, the bent flip block 241 is at a certain angle position. At this time, the end of the pushing portion of the bent flip block 241 is located on the moving path of the moving push block 231.

[0029] The extrusion push block 243 is hingedly mounted on one end of the bent flip block 241, so the bent flip block 241 has a certain angle adjustment function, so that the extrusion push block 243 can press the metal sheet 235 tightly into contact with the pins of the plug to ensure the stability of the electrical connection between the two. A stop block 245 is fixed to the side of the bent flip block 241 close to the extrusion push block 243. The stop block 245 is used to limit the maximum stroke of the extrusion push block 243 to flip toward the side of the bent flip block 241.

[0030] There are two reset assemblies, which are respectively arranged on both sides of the rectangular mounting frame 21. The reset assembly includes two gears 251, which are respectively fixed to the ends of the first mounting shafts on the same side of the reset of the two expandable connection assemblies. That is, when in use, the rotation directions of the two first mounting shafts are consistent. A rack 252 is slidably provided on the outer side of the rectangular mounting frame 21, and the gear 251 is meshed with the two racks 252. A liquid crystal elastic strip 253 is fixed between the rack 252 and the rectangular mounting frame 21.

[0031] Liquid crystal elastic strips 253 are made of liquid crystal elastomers. Liquid crystal elastomers (LCEs) are a unique polymer material that combines the ordered molecular arrangement of liquid crystals with the flexibility of elastomers. At the molecular level, this material possesses the ordered structure of a liquid crystal phase while exhibiting the reversible deformation capabilities of an elastomer at a macroscopic level. Liquid crystal elastomers exhibit a negative thermal expansion coefficient, meaning their volume decreases as temperature increases.

[0032] A fault maintenance hole 14 corresponding to the rack 252 is provided on the shell. The fault maintenance hole 14 can be located on the side or front of the shell. When the movable push block 231 is clamped by the two bent flip blocks 241 and cannot rebound smoothly, a thin rod can be inserted into the fault maintenance hole 14 to push the rack 252 to move. The first mounting shaft is driven to rotate by the gear 251, and the power transmission roll 233 is pulled and wound onto the first mounting shaft, driving the movable push block 231 to move until the movable push block 231 is no longer clamped by the two bent flip blocks 241. Then, the power transmission roll 233 drives the first mounting shaft to rotate under the elastic force of the spiral spring, and the power transmission roll 233 is smoothly rewound to the first mounting shaft to resolve the fault.

[0033] The electrical circuit mechanism is used to electrically connect an external power supply with the fixed metal contact terminal 22; the electrical circuit mechanism includes a wiring terminal 31 installed inside the shell, and the wiring terminal 31 is electrically connected to two conductive copper wires 32. The positive and negative poles of the wiring terminal 31 are respectively connected to the two conductive copper wires 32, and the two conductive copper wires 32 are respectively electrically connected to the two fixed metal contact terminals 22 in a single plug-in mechanism 2. A wire mounting hole 15 corresponding to the wiring terminal 31 is opened on the shell, and the wire mounting hole 15 is used for the wire to pass through for connection and installation with the wiring terminal 31.

[0034] When in use, the two pins of the plug are respectively inserted into the two sockets 13, and the two movable push blocks 231 are respectively in contact with the two pins of the plug. The two movable push blocks 231 will be pushed to slide along the slide groove 25 until the movable metal contact terminal 232 is connected with the fixed metal contact terminal 22. The spiral spring will be pulled to deform and store force. In this process, the movable push block 231 will contact the pushing part of the bent flip block 241, and the bent flip block 241 will rotate a certain angle along the second mounting axis. The extrusion push block 243 is flipped toward the side of the plug pin until the end of the pushing portion of the bent flip block 241 is tightly pressed against the side of the movable push block 231. The flip portion of the bent flip block 241 has a certain degree of flexibility and can produce a certain degree of deformation. At this time, the extrusion push block 243 will press the metal sheet 235 tightly, so that the metal sheet 235 is in close contact with the plug pin, and the plug can be powered on. Under the action of the two bent flip blocks 241, the plug pin and the movable push block 231 will be clamped.

[0035] When the plug is pulled out, the two bent flip blocks 241 lose their clamping force, the movable push block 231 is released, and the two power transmission coils 233 will be wound onto the first mounting shaft under the force of the spiral spring until they return to their original positions. The two bent flip blocks 241 will then return to their original positions under the force of the torsion spring 242, ready for next use.

[0036] When a plug is inserted into the socket, the liquid crystal elastic strip 253 is in a stretched state. If the temperature inside the housing rises at this time, the liquid crystal elastic strip 253 will shrink. When the liquid crystal elastic strip 253 shrinks, it will pull the rack 252 to move, and further drive the first mounting shaft to rotate through the gear 251. The power transmission coil 233 will be pulled and rewound onto the first mounting shaft, causing the movable push block 231 to return to its original position and automatically eject the plug. In addition, to ensure the sensitivity of the liquid crystal elastic strip 253, a through hole can be opened in the rectangular mounting frame 21.

[0037] The above are only preferred embodiments of the present invention and are merely illustrative, not restrictive, of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the embodiments within the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
