Socket with five-hole insertion detection function

Abstract

The invention discloses a socket with a five-hole insertion detection function. The socket comprises a panel and a safety door arranged in the panel. A groove is arranged in the panel, a first squarethrough hole is arranged in a first inner wall of the groove, and a second square through hole is arranged in a second inner wall of the groove; a top of the panel is provided with a triangular jack and a two-angle jack; the safety door comprises a first sliding piece and a second sliding piece which are connected through an elastic element; a first contact surface is arranged on the first slidingpiece, and a second contact surface is arranged on the second sliding piece; when a triangular plug is inserted into the safety door through the triangular jack, the first sliding piece slides in a direction perpendicular to the first inner wall, and the first contact surface penetrates through the first square through hole to make contact with a first touch switch; and when a two-angle plug is inserted into the safety door through the two-angle jack, the second sliding piece slides in the direction perpendicular to the second inner wall, and the second contact surface penetrates through thesecond square through hole to make contact with the second touch switch. The socket is low in cost and high in detection reliability.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a socket with a five-hole insertion detection function. Background technique [0002] During the use of household appliances or industrial equipment, there is often a phenomenon of poor contact between the plug and the socket, causing the appliance to fail to work normally, and even the current of some wire cores is too large because the resistance of the cross-sectional area of ​​the wire is reduced due to the virtual connection of the wire. , thus generating a large amount of heat to melt the insulating layer of the wire, causing the insulating layer to catch fire and igniting nearby combustibles, causing a fire. However, most of the reasons for this situation are that the quality of the power socket is too poor, and the internal metal sheet is too thin and has poor elasticity, which is prone to deformation and leads to poor contact with the plug.

[0002] During the use of household appliances or industrial equipment, there is often a phenomenon of poor contact between the plug and the socket, causing the appliance to fail to work normally, and even the current of some wire cores is too large because the resistance of the cross-sectional area of ​​the wire is reduced due to the virtual connection of the wire. , thus generating a large amount of heat to melt the insulating layer of the wire, causing the insulating layer to catch fire and igniting the nearby combustibles, causing a fire

However, most of the reasons for this situation are that the quality of the power socket is too poor, and the internal metal sheet is too thin and has poor elasticity, which is prone to deformation and leads to poor contact with the plug.

[0003] For the detection of whether the plug is inserted into the socket, the traditional method is to use the naked eye observation and hand touch test method, which is simple but inefficient; and the high-power electrical equipment uses the temperature sensor added inside the socket to detect the contact resistance. The purpose of plug insertion detection, this method is also difficult to achieve real-time detection and will affect the equipment business

Considering that the basic functions of the socket are not affected and the internal space is not occupied, a more efficient and convenient detection socket has not yet been proposed.
