Cylindrical surface contact connection assembly

Abstract

The invention relates to a cylindrical surface contact connection assembly, which includes a terminal, a deformation arm and a plurality of arc-shaped contact pieces; the terminal is a cylindrical structure; the top of the arc-shaped contact piece is a free end, and the center forms a cylindrical shape The cavity; the bottom of the arc-shaped contact piece is connected to the terminal through the deformation arm as an integral structure; the outer side of the arc-shaped contact piece is provided with a spring. The present invention newly adds the extended part of the cylindrical socket as the deformation part, and arranges a coil spring or a spring leaf at the front end of the deformation part, so that the inner diameter of the front end of the deformation part is smaller than the cylindrical plug, so that the insertion part of the cylindrical plug fully contacts.

Description

technical field [0001] The invention relates to a cylindrical surface contact connection assembly. Background technique [0002] Traditional sockets are divided into industrial use and civilian use. According to the number of jacks, they can be divided into single plug, two plugs, three plugs, four plugs, five plugs, etc. The width of the contact piece of the flat plug is 7, 9, 13, 16mm (mm), etc., and the length is 18, 21, 26, 29, 36, 38mm (mm), etc. At present, the plugs of various household appliances and electrical equipment are mostly flat, so the sockets are usually designed as flat jacks, but industrial sockets or connectors are all round-pin plugs, so they need to be installed on traditional sockets with flat jacks. It can only be used after installing the adapter device. Moreover, the diameter of the round pin of the plug is 2mm, 4.8mm, 6mm, 8mm, etc. The existing cylindrical socket is processed by brass or alloy, and its inner diameter is larger than the inner di...

AI Technical Summary

Problems solved by technology

[0003] Affected by plug terminal fixation and dimensional error, socket assembly production process and production process error, or deformation caused by extrusion and collision during normal use, it is almost impossible for the plug copper sheet and socket copper sheet to be in parallel and close contact, and there is a certain position between the two. Or angle error, contact area and insertion force are not ideal, too large or too small and extremely unstable, most of them can only achieve line contact or point contact

Point contact or line contact can easily cause the surface area of ​​the contacted object to become smaller, which can easily cause poor contact, increase in temperature, cause fire or reduce the stability of the equipment. It will cause a lot of inconvenience in use, and the performance is also very unstable

[0004] Due to the low conductivity of the brass contacts or the influence of socket assembly process and production process errors, the resulting position error can only achieve small-area line contact, and it is easy to cause unstable insertion force, small contact area, and poor user feel. question
