Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a socket with an over-temperature protection structure. Background Art

[0002] A socket is a seat into which one or more circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits.

[0003] In daily production and life, the use of power sockets is indispensable, but the risks of electricity use are always accompanied. Serious fire accidents caused by charging sockets or wires catching fire occur from time to time. The root cause is that the contact pieces of the charging sockets or the plugs are oxidized and dirty over the years, resulting in poor contact and a lot of heat at the plug, which eventually causes fire accidents. On the other hand, during the installation of traditional sockets, the socket body and the shell are disassembled and installed. During the installation process, a flat-blade screwdriver is needed to dock with the bottom of the socket and rotate the flat-blade screwdriver to assist in disassembly. Because the socket connection is too tight, the flat-blade screwdriver is easily misplaced, causing scratches on the outer surface of the socket body or on the outer surface of the wall.

[0008] As a preferred technical solution of the utility model, a card slot is provided on the side of the fixing plate close to the top, and the shape and size of the inner wall of the card slot are matched with the shape and size of the side of the card block close to the bottom.

[0009] As a preferred technical solution of the utility model, there are two grooves, and the two grooves are respectively opened at the top and bottom of the shell, the inner walls of the two grooves are rotatably connected to a block, and the side surfaces of the two blocks are completely consistent with the connection structure of the fixed plate.

[0010] As a preferred technical solution of the utility model, a docking groove is provided on the side of the fixed plate, a circular groove is provided on the side of the auxiliary plate, a bolt is provided on the inner wall of the circular groove, and the side of the bolt passes through the inner wall of the circular groove and the inner wall of the docking groove and is rotatably connected to the side of the docking groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The socket with over-temperature protection structure uses a temperature control switch in conjunction with the neutral wire connection slot. The live wire connection slot, the neutral wire connection slot and the ground wire connection slot inside the connection block are connected to the live wire, the neutral wire and the ground wire respectively, and the device is assembled and used. When the socket is connected to the plug, the temperature control switch detects the temperature in the circuit. When it detects that the contact has an over-temperature hazard, the device can cut off the power supply line in time until the contact temperature drops to a reasonable range. The device restores the power supply line connection and supplies power again.

[0013] 2. The socket with an over-temperature protection structure uses a card block and a groove in cooperation. The card block is rotated on the top of the shell until the side of the card block is docked with the inner wall of the groove, thereby assisting the shell and the fixed plate to be stably docked and assembled. When the device needs to be dismantled, the card block is rotated until the side of the card block is away from the inner wall of the groove, thereby moving the shell away from the fixed plate for disassembly.

[0014] 3. The socket with over-temperature protection structure is equipped with a temperature control switch. When the temperature is too low, the device is usually disconnected. When the temperature is lower than the set value, the device is closed and the power is turned on. The load heater heats the environment. When the ambient temperature reaches the preset temperature, the device returns to the disconnected state, thereby ensuring that the ambient temperature is within a reasonable range.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 A socket with an over-temperature protection structure comprises a shell 1, a fixed plate 2 is slidably connected to the inner wall of the shell 1, an auxiliary plate 3 is fixedly installed on the side of the fixed plate 2, a notch 4 is provided on the side of the fixed plate 2, a temperature control switch 5 is fixedly installed on the inner wall of the notch 4, a wiring block 6 is fixedly installed on the side of the fixed plate 2 away from the auxiliary plate 3, a groove 11 is provided on the top of the shell 1, a card block 10 is rotatably connected to the inner wall of the groove 11, and the temperature control switch 5 is installed. The temperature control switch 5 adopts KSD9700 ceramic temperature control switch 5 with holes. The KSD9700 series product is a thermostat using a bimetallic strip as a temperature sensing component. When the electrical appliance is working normally, the bimetallic strip is in a free state and the contact is in a closed / open state. When the temperature rises to the action temperature value, the bimetallic component is heated to generate internal stress and quickly acts to open / close the contact and cut off / connect the circuit, thereby playing a thermal protection role. When the temperature gradually drops to the reset temperature, the contacts automatically close / disconnect and resume normal working state. On the basis of the traditional socket, temperature sensing and response devices are added inside the power socket and in the power supply link. Under normal circumstances, when the contact is detected to be overheated, the device can cut off the power supply line in time until the contact temperature drops to a reasonable range, and the device restores the power supply line connection and supplies power again. The above is for the case of excessively high temperature. Conversely, it can also be applied to the case of too low temperature. Under normal circumstances, the device is disconnected. When the temperature is lower than the set value, the device closes and connects the power supply, and the load heater heats the environment. When the ambient temperature reaches the preset temperature, the device returns to the disconnected state, thereby ensuring that the ambient temperature is within a reasonable range.

[0024] In a preferred embodiment, a live wire connection slot 7 is opened on the side of the terminal block 6, a neutral wire connection slot 8 is opened on the side of the terminal block 6, and a ground wire connection slot 9 is opened on the end of the side of the terminal block 6 away from the neutral wire connection slot 8. The opening of the live wire connection slot 7 and the neutral wire connection slot 8 assists the stable assembly and docking of the live wire and the neutral wire, and the opening of the ground wire connection slot 9 assists the stable assembly and docking of the ground wire.

The temperature control switch 5 is connected to the inner wall of the neutral wire wiring slot 8, so that the temperature is detected by the temperature control switch 5. When the temperature is too high, the auxiliary neutral wire is powered off, thereby powering off the auxiliary device.

[0026] In a preferred embodiment, a card slot 12 is opened on the side of the fixing plate 2 near the top, and the shape and size of the inner wall of the card slot 12 are adapted to the shape and size of the side of the card block 10 near the bottom. By using the card slot 12 and the card block 10 in coordination, the inner wall of the card slot 12 is connected to the side of the card block 10 to assist in the stable positioning of the fixing plate 2 and the housing 1.

[0027] In a preferred embodiment, there are two grooves 11, and the two grooves 11 are respectively opened at the top and bottom of the shell 1, the inner walls of the two grooves 11 are rotatably connected to a block 10, and the side surfaces of the two blocks 10 are completely consistent with the connection structure of the fixed plate 2, and by opening the two grooves 11, stable limiting is performed at the top and bottom of the shell 1.

[0028] In a preferred embodiment, a docking groove 13 is opened on the side of the fixing plate 2, and a circular groove 14 is opened on the side of the auxiliary plate 3. A bolt is set on the inner wall of the circular groove 14, and the side of the bolt passes through the inner wall of the circular groove 14 and the inner wall of the docking groove 13 and is rotatably connected to the side of the docking groove 13. By opening the docking groove 13 and the circular groove 14, the auxiliary bolt passes through the inner wall of the circular groove 14 and the inner wall of the docking groove 13, and the bolt is rotated in the inner wall of the circular groove 14, so that the auxiliary bolt is docked with the required installation position of the wire box.

[0029] Working principle: when the device is used, the live wire connection slot 7, the neutral wire connection slot 8 and the ground wire connection slot 9 inside the wiring block 6 are connected to the live wire, the neutral wire and the ground wire respectively, and the device is assembled and used. When the socket is connected to the plug, the temperature control switch 5 detects the temperature in the circuit. When the contact is detected to be over-temperature dangerous, the device can cut off the power supply line in time until the contact temperature drops to a reasonable range. The device restores the power supply line connection and supplies power again. In the case of too low temperature, the device is usually disconnected. When the temperature is lower than the set value, the device is closed and the power is turned on. The load heater heats the environment. When the ambient temperature reaches the preset temperature, the device returns to the disconnected state, thereby ensuring that the ambient temperature is within a reasonable range.
