Description

Technical Field

[0001] The utility model relates to the technical field of power sockets, in particular to a power socket with a leakage protection function. Background Art

[0002] At present, people are paying more and more attention to electricity safety, and there are many accidents caused by electric shock every year. There are also cases where the socket is overheated or even catches fire due to excessive load, false connection, and short circuit that cannot be identified in time. Old residential areas or mountainous and rural areas may have problems such as aging circuits or too thin pre-buried wires, which are not suitable for the operation of current high-power equipment, and users often cannot discover them in time. Therefore, using high-power equipment in these scenarios to overload the power cord often causes the power cord to overheat or catch fire.

[0003] There is a positive correlation between the size of the wire diameter and the maximum load it can carry. When the wire diameter is too thin, it obviously cannot bear the normal use of electrical appliances. In some other power usage scenarios, users may be electrocuted and the leakage protector may fail or the leakage protector may not be installed in the user's power usage scenario.

[0004] In response to the above problems, the present application proposes a power socket with a leakage protection function, which can effectively avoid electric shock and reduce the occurrence of accidents. When it is detected that the socket temperature is too high, an alarm will be given to the user in time to allow the user to adjust the load or cut off the circuit; the wire diameter can be fundamentally identified, and when the wire diameter is too thin, the socket cannot be powered on normally, thereby ensuring the safety of the user.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] See also Figure 1-Figure 7 The utility model provides a technical solution: a power socket with leakage protection function, comprising: a front panel 1 and a rear shell 2, the front panel 1 is provided on one side of the rear shell 2; a copper socket 3 is provided on one side of the front panel 1, a copper upper and lower connecting piece 4 is provided on the outer side of the copper socket 3, wire interfaces 28 are provided on both sides of the inner part of the copper upper and lower connecting piece 4, a ground connecting piece 7 is provided in the middle of the copper upper and lower connecting piece 4, and a ground connecting wire 8 is provided at one end of the ground connecting piece 7.

[0032] It also includes: a leakage protection device 15 arranged on the rear shell 2, which is used to quickly cut off the power supply when the socket leaks; the leakage protection device 15 includes a leakage protection device protective shell 9, and the leakage protection device 15 also includes a coil 31 arranged inside the leakage protection device protective shell 9, one end of the coil 31 is connected to an armature 17, an electromagnetic coil 35 is arranged under the armature 17, and a plurality of wires 26 are arranged inside the coil 31, one of the wires 26 is provided with wire connecting posts 14 at both ends, one of the wire connecting posts 14 is electrically connected to the wiring hole 34 of the live wire, and the other wire connecting post 14 is electrically connected to the wiring hole 34 of the neutral wire.

[0033] After the wires pass through the interface, they are connected to the leakage protection link in front by the conductor pole. The leakage protector is connected to the live and zero wires. When the equipment is operating normally, the current in the line is in a balanced state and the leakage protection switch is closed. When the electrical equipment leaks electricity, the current in the line is not equal. The leakage protection will identify these subtle differences and quickly cut off the switch. The leakage protection can cut off the power in time when the equipment leaks electricity to avoid the risk of electric shock.

[0034] A wire diameter limiter 11 is arranged on both sides of the leakage protector protective shell 9, and is used to clamp the wire diameter of the connected wire. Limit springs 12 are arranged on both sides of the wire diameter limiter 11; a wiring hole 34 is arranged inside the leakage protector protective shell 9, and there are three wiring holes 34. The three wiring holes 34 are used to connect the live wire, the neutral wire and the ground wire, among which the wiring hole 34 connecting the ground wire is located in the center, and the wiring holes 34 connecting the live wire and the neutral wire are located on both sides. A connecting wire pressing post 10 is arranged in the wiring hole 34, and a wire diameter limiter 11 is arranged inside the wiring hole 34 connecting the live wire and the neutral wire. The wire diameter limiter 11 is semicircular in shape, and the wire diameter limiter 11 is electrically connected to the limit stopper 13. When the wire diameter limiter 11 cannot clamp the wire, the limit stopper 13 is in an open circuit state.

[0035] The user's wire is inserted into the socket and connected to the live wire, neutral wire and ground wire interfaces in the socket. There is a wire diameter limiter 11 in front of the live wire and neutral wire interfaces in the socket. The limit springs 12 on both sides of the wire diameter limiter 11 always clamp the wires, but there are size requirements for the wire diameter. When the wire diameter is too thin and the wire diameter limiter 11 cannot be fully clamped, the limit blocker 13 will always be in a disconnected state, and the socket will also be in a disconnected state and cannot be powered normally. Only when the wire diameter reaches the specified diameter can the socket be charged normally.

[0036] The leakage protection test button is arranged on one side of the front panel 1, and is used to test the function of the leakage protection device 15. One end of the leakage protection test button is connected to the test port connector 20; one side of the top of the coil 31 is electrically connected to the test resistor 18, and a test port connector fixing frame 19 is arranged on one side of the front panel 1.

The test port connector pressing trigger 21 is electrically connected to the test resistor, and a single-pole switch 32 is arranged on the connection circuit. A switch connector lifting single-pole switch device 30 is arranged on one side of the switch connector 6, which is used to lift and open the single-pole switch 32. An insulating silicone 33 is arranged on one end of the switch connector 6 close to the single-pole switch 32.

[0037] The leakage protection link has a test button, and the test button is connected to the test button of the front panel 1 through the test port connector pressure trigger 21 and the test port connector 20. To facilitate the fixation of the test port connector 20, a test port connector fixing frame 19 is provided under the test port connector 20 to fix it. The test port connector 20 is facing the test port connector return spring 22. After pressing the test button of the front panel 1, the elastic potential energy of the spring causes the test port connector 20 to return.

[0038] When the test port connector push trigger 21 is pushed down, the single-pole switch 32 is closed. To open the single-pole switch 32, the switch connector 6 in front can lift it up. The part where the switch connector 6 is connected to the single-pole switch 32 is provided with insulating silicone 33.

[0039] The heat sink 25 is arranged on one side of the front panel 1 and is used for heat dissipation when the socket is at high temperature. The bottom of the heat sink 25 is electrically connected to a bimetallic temperature control switch 23, and the bimetallic temperature control switch 23 is electrically connected to a buzzer 27. Heat sinks 24 are arranged on both sides of the copper socket 3, and one of the heat sinks 24 is in contact with the bimetallic temperature control switch 23.

[0040] The radiator 25 is controlled by the bimetallic temperature switch 23. When the temperature reaches a certain value, the radiator 25 opens to dissipate heat. At the same time, the bimetallic temperature switch 23 also controls the buzzer 27. When the load is too large or the temperature is too high, the buzzer 27 will sound an alarm to remind the power user to control the load or cut off the circuit in time.

[0041] The copper socket 3 includes a two-pin copper socket located at the top and a three-pin copper socket located at the bottom. The copper upper and lower connection pieces 4 are electrically connected to the copper socket 3. A switch connector socket 5 is provided on one side of the copper upper and lower connection pieces 4. A switch button 29 is provided on one side of the front panel 1. A switch connector 6 is provided at one end of the switch button 29. The switch connector socket 5 faces the switch connector 6. A switch return spring 16 is provided on the outer side of one end of the switch connector 6.

[0042] After passing through the leakage protection link, the wire is connected to the copper upper and lower connecting piece 4 in front, and the copper upper and lower connecting piece 4 connects the two plugs above and the three plugs below. On one side of the copper upper and lower connecting piece 4, the connecting piece is disconnected and provided with a switch connector socket 5, which is directly opposite to the switch connector 6. When the switch button 29 is pressed, the switch connector 6 is inserted into the switch connector socket 5, the entire circuit is closed, and the socket can be powered normally. When the switch is pressed again, the switch connector 6 is bounced open in the switch connector socket 5 by the elastic force of the switch return spring 16, and the entire socket is powered off.

[0043] Working principle: During the use of the power socket, when the user's socket wiring is too thin and below a certain limit, the clamping device on the wire diameter limiter 11 cannot clamp the wire normally, and it is determined that it is obviously unable to withstand the load and the power socket cannot supply power normally, which can fundamentally ensure the user's power safety.

[0044] When the wire diameter is too thin and may not be suitable for the operation of high-power products, and the user cannot promptly detect the heating, fire, etc. that may be caused by excessive load or loose connection, the buzzer 27 in the socket can sound an alarm after the socket temperature rises to a certain limit, reminding the user to pay attention to controlling the load or reminding the user to cut off the power supply.

[0045] In some electricity usage scenarios, users may get electric shock while the leakage protector fails or the leakage protector is not installed in the user's electricity usage scenario. In this case, the device is designed with a leakage protection function. When the risk of electric shock is detected, the power supply can be automatically cut off to ensure the safety of the people using electricity.
