Description

Waist drum-shaped hair button and connector

Technical Field

The application belongs to the technical field of connecting elements, and particularly relates to a waist drum-shaped hair button and a connector.

Background

The fuzz button is used as a special connecting element, and can realize vertical welding-free interconnection because the fuzz button can realize axial elastic shrinkage deformation when being axially pressed. In miniaturized and densely arranged occasions, both the radio frequency and low frequency connection fields are more and more favored. Although the fuzz button is applied in China for a long time, some problems are still not completely solved, wherein the problem of fixing the fuzz button in a mounting hole exists, and particularly in the situation that the fuzz button is exposed. As described in the background of the invention patent publication "CN 106099453A", two applications of the primary fuzz button were first developed, one being through-hole-insertion and the other being metal-cap-clamping. The through hole is embedded, the fuzz button is not fixed, and the field assembly is difficult. The two ends of the metal caps are clamped, the structure is relatively complex, the number of parts and the axial height are increased, miniaturization and shortening are not facilitated, meanwhile, two contact surfaces are also increased, and two risk points are increased during vibration.

Regarding the fixation of the fuzz button in the mounting hole, related manufacturers and users conduct some research and exploration, and also obtain some achievements, and each has advantages and limitations.

For example, the utility model patent with publication number "CN 207149739U" and name "a fuzz button connector" realizes the fixation of fuzz button in the module by pressing a positioning pin or glue into the middle part of the side surface of the module. The problem that the pressing and positioning pin or glue injection degree is not easy to control and the multi-channel densely-arranged central area cannot be operated exists in the mode. And as the invention patent with the publication number of 'CN 106099453A' and the name of 'wool button connector and insulator and wool button', the invention provides a wool button and a mounting hole which are arranged in a step shape in the axial direction to realize the axial fixation of the wool button, the wool button and the mounting hole in the mode are both required to be arranged in a step shape, the radial dimension is increased, and the application is limited in the use occasion with extremely small channel spacing. Also, as disclosed in the utility model patent with publication number "CN 210744235U" entitled "a fuzz button assembly, transmission module and connector thereof," this patent forms a step for axial fixation by adding a bushing member on the fuzz button body, and this way adds parts, is somewhat complicated in structure, and puts forward higher requirements for process control.
