Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a universal socket with an insertion detection function. Background Art

[0002] During the use of household appliances or industrial equipment, poor contact between the plug and the socket often occurs, causing the appliance to malfunction. The current in some wire cores may even be too large because the resistance of the wire cross-sectional area is reduced due to the virtual connection of the wire, thus generating a large amount of heat to melt the insulation layer of the wire, causing the insulation layer to catch fire and ignite nearby combustibles, causing a fire. However, the reason for this situation is mostly that the quality of the power socket is too poor, the metal sheet inside is too thin and has poor elasticity, and it is easy to deform, resulting in poor contact with the plug.

[0003] To detect whether a plug is connected to a socket, visual observation and hand touch testing methods are usually used. The socket requires regular manual maintenance, which is inefficient and the MCU cannot detect whether the plug is inserted. For high-power electrical equipment, a temperature sensor is added to the socket to detect the contact resistance, but the premise is that it needs to run for a period of time, so poor contact cannot be discovered in time. Although this method can effectively avoid accidents, it will cause an immediate interruption of power supply, and the equipment service will be interrupted. Summary of the invention

The three-pole jack 71 is provided with the holes for the neutral wire, live wire and ground wire according to the rule of "ground on top, neutral on the left and live on the right" to adapt to the triangular plug of the household appliance.

[0042] The safety door 2 includes a fixing member 21 and a sliding member 22 connected by an elastic element; the fixing member 21 is fixed in the partition groove 41, and a ground wire insertion portion 913 corresponding to the position of the ground wire jack 713 is provided on the fixing member 21; a first neutral wire insertion portion 911 corresponding to the position of the first neutral wire jack 711, a first live wire insertion portion 912 corresponding to the position of the first live wire jack 712, and a copper sheet 6 in contact with the metal contact group 5 are provided on the sliding member 22. When a triangular plug is inserted into the safety door 2 through the triangular jack 71, the sliding member 22 slides in a direction perpendicular to the first inner wall of the partition groove 41, and the copper sheet 6 is separated from the metal contact group 5.

[0043] Regarding the connection design between the fixing member 21 and the sliding member 22, Figure 2 The first embodiment of the present invention is as follows: Figure 2 As shown, a first protruding cylinder is provided on a side of the fixing member 21 facing the sliding member 22, a connecting groove is provided on a side of the sliding member 22 facing the fixing member 21, a second protruding cylinder corresponding to the first protruding cylinder is provided in the connecting groove, and the first protruding cylinder is connected to the second protruding cylinder through the first spring 101. Figure 3 The second embodiment of the present invention is as follows: Figure 3 As shown, the elastic element includes a second spring 102 and a third spring 103, a third protruding cylinder and a fourth protruding cylinder are symmetrically arranged on one side of the fixed member 21 facing the sliding member 22, and a fifth protruding cylinder and a sixth protruding cylinder are symmetrically arranged on one side of the sliding member 22 facing the fixed member 21; the fifth protruding cylinder corresponds to the third protruding cylinder, and the third protruding cylinder is connected to the fifth protruding cylinder through the second spring 102; the sixth protruding cylinder corresponds to the fourth protruding cylinder, and the fourth protruding cylinder is connected to the sixth protruding cylinder through the third spring 103. Both of these connection methods can ensure that the sliding member 22 is retracted under force, and are not limited in the present invention.

[0044] During the specific implementation, the elastic element has a restraining effect on the safety door 2, and the direction of its elastic force is toward the fixing member 21. When the sliding member 22 moves toward the fixing member 21 on the partition 4 due to the external force applied by the triangular plug after passing through the triangular socket 71, the copper sheet 6 and the metal contact group 5 are controlled to be separated by force; when the triangular plug is pulled out of the triangular socket 71, the copper sheet 6 and the metal contact group 5 are controlled to automatically reset and contact, and the implementation method is relatively simple and reliable, and the structural design is simple and easy to obtain.

The purpose of setting the T-shaped cylindrical surface is to expand the contact area, to ensure that the metal contact group 5 and the copper sheet 6 can be fully in contact with each other to the greatest extent, and to avoid detection abnormalities.

[0047] Since the metal contact group 5 and the copper sheet 6 have good electrical conductivity, with the copper sheet 6 as the contact conductive surface, when the internal DC power supply is energized to the metal contact group 5, the first metal contact 51 and the second metal contact 52 will form a loop by contacting the copper sheet 6.
