Contractible socket

Abstract

The invention provides a contractible socket. A professional elastic element and a professional elastic mechanism are arranged on one side of the socket conductive contact body, so that the socket conductive contact body and the conductive contact body of the plug are elastically pressed continuously, and the purpose of long-lasting good contact is achieved. In order to further ensure that the socket and the plug are in good durable contact, the elastic element is a spring made of a professional spring steel wire; in order to further improve the scientific and reasonable elastic pressing socket conductive contact body of the spring, a positive electrode movable contact column, a positive electrode insulating cap, a positive electrode wire reaching sheet, a negative electrode insulating cap, a negative electrode wire reaching sheet and a negative electrode movable contact column are arranged in a matching manner; and the parts are combined and arranged in two insulators, and finally a shell is sleeved, so that the hidden socket with excellent contact performance is manufactured. The problems that an existing socket is poor in contact, an electric conductor is exposed and touches a wire, and plugging and unplugging of a plug are strenuous can be solved, and the purposes of improving charging and discharging performance of a storage battery and improving working efficiency and power utilization safety of storage battery vehicles and storage battery equipment are achieved.

Description

technical field [0001] The invention relates to a power supply connection accessory, in particular to a retractable socket. [0002] technical background [0003] Among the many power connectors, the safety of electric vehicle sockets is closely related to our lives. However, there are still many defects and deficiencies in existing products, which have caused unnecessary losses and dangers to our lives. Common problems in reality are: : The problem of poor contact of the positive and negative conductors of the socket. Generally speaking, when the socket is first used, the conductor is okay. After a period of use, the contact with the plug will form a phenomenon of poor contact, which will cause ignition and fire accidents, and long-term Poor contact will cause harm to the battery and affect the service life of the battery; the problem of accidental short circuit of the positive and negative poles of the socket, the media often report that the socket of the battery car hurts ...

Problems solved by technology

[0004] In order to solve the defects and deficiencies in the technical background, the present invention provides a kind of: retractable socket, which can effectively solve the problem of poor contact of the socket, the problem of accidental short circuit of the positive and negative poles, and the problem of laborious insertion and removal of the socket plug

[0005] The solution of the present invention to solve the technical problem is: in order to solve the problem of poor contact of the positive and negative conductors of the battery car socket; we have found through research and disassembly of the existing problem battery car socket that the reasons for the poor contact are: due to the existing socket plug. The conductive connection is achieved by the surface contact of the conductors of the plug and socket, and the continuous stability of the surface contact is maintained by the elasticity of a certain conductor of the plug or socket; therefore, when the plug and socket are often plugged and pulled out, it is easy to Gradually attenuate the self-elasticity of the conductor until the elasticity is completely lost, so that the contact conductor between the plug and the socket has no elastic force to maintain contact, resulting in the phenomenon of sometimes contacting and sometimes not contacting, so the problem of poor contact between the plug and the socket is caused; in order to solve We have designed a solution to this problem: a professional elastic element and mechanism are arranged on the side of the conductive contact body of the socket to continuously perform the contact between the conductive contact body of the spring-pressed socket and the conductive contact body of the plug, and achieve the purpose of good permanent contact; In order to further ensure good permanent contact between the socket and the plug, the elastic element is a compression spring made of professional spring steel wire; in order to further improve the scientific and reasonable spring pressure socket conductive contact body, a positive movable contact column, Positive pole insulating cap, positive pole reaching wire piece, negative pole insulating cap, negative pole reaching wire piece, negative pole movable contact column; and these components are combined and installed in two insulators, and finally put on the shell to make a shrinking socket with excellent contact performance ; It can solve the problems of poor contact of existing sockets, exposed conductors touching wires, and laborious plug insertion and removal, and achieve the purpose of improving battery charging and discharging performance, improving the working efficiency and electricity safety of battery cars and battery-using equipment
