Plug and socket assembly with replaceable conductive strips

Abstract

The invention discloses a plug and socket assembly with a replaceable conductive sheet. The plug and socket assembly comprises a plug body and a socket body. The plug body comprises a housing and a rear cover fixed at the tail end of the housing. Two conductive columns which are vertically distributed are fixed in the housing. The front end of each conductive column is provided with a conductive sheet used for inserting into the socket body to realize electrical connection with the conductive base in the socket body. A cylindrical thread block is integrally formed on the tail end of each conductive sheet. The front end of each conductive column is provided with a thread hole in which the thread block can be screwed. The thread block arranged on each conductive sheet is threaded in the thread hole in the corresponding conductive column. The internal conductive sheet and the conductive column in the socket body are installed together through thread connection so that the conductive sheetcan be replaced separately after an oxide layer is generated on the outer surface of the conductive sheet, i.e. the whole socket body does not need to be replaced, and thus use can be facilitated forusers.

Description

technical field [0001] The invention relates to the technical field of electrical connection devices, in particular to a plug and socket assembly with replaceable conductive sheets. Background technique [0002] At present, when the plugs and sockets on the market are in use, after the conductive sheet in the plug is inserted into the conductive seat in the socket, the plug can realize the electrical connection with the socket; but during the long-term use of the plug, the conductive sheet in the plug It is easy to produce an oxide layer on the outer surface of the conductive sheet, or, when the plug is plugged in and out of the socket, if a spark is generated between the conductive sheet and the conductive seat, it is easy to cause an oxide layer on the outer surface of the conductive sheet, and on the outer surface of the conductive sheet After the oxide layer is formed on the surface, it will lead to poor contact between the plug and the socket. In this way, it will affec...

[0002] At present, when the plugs and sockets on the market are in use, after the conductive sheet in the plug is inserted into the conductive seat in the socket, the plug can realize the electrical connection with the socket; but during the long-term use of the plug, the conductive sheet in the plug It is easy to produce an oxide layer on the outer surface of the conductive sheet, or, when the plug is plugged in and out of the socket, if a spark is generated between the conductive sheet and the conductive seat, it is easy to cause an oxide layer on the outer surface of the conductive sheet, and on the outer surface of the conductive sheet After the oxide layer is formed on the surface, it will lead to poor contact between the plug and the socket. In this way, it will affect the normal power supply to the electrical equipment, and even cause flashover due to poor contact between the conductive sheet and the conductive seat, which is easy cause a fire; however, since the conductive sheet installed in the plug and the plug are fixed in one body, after the oxide layer is formed on the outer surface of the conductive sheet, there is a disadvantage that the conductive sheet cannot be replaced separately
