[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 easil...

Embodiment Construction
[0030] see figure 1 , the structure of the preferred embodiment of the present invention includes terminal 2, four arc-shaped contact pieces 1 and a new deformable arm 5, the length is about 0.5-2cm (centimeter), one end of the deformable arm is connected with the terminal, the other of the deformable arm One end is connected with four arc-shaped contact pieces, and a spring piece is arranged at the front end of the deformable arm. The contraction force of the spring piece makes the inner diameter of the front end of the deformable arm smaller than the outer diameter of the cylindrical plug. The outer diameter is tight fit, that is, the inner diameter of the slot part of the cylindrical socket is the same as the outer diameter of the cylindrical plug. The main function of the set coil spring or spring leaf is to shrink the deformed part. The inner diameter is equal to or smaller than the cylindrical plug. The contraction force includes deformation. The contraction force of the...

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...
