Anti-falling fuzz button convenient to install

Abstract

The invention relates to an anti-falling fuzz button convenient to install. The anti-falling fuzz button convenient to install comprises a fuzz button body; the cross section of the fuzz button body is in an oval columnar shape; the long axis of the cross section of the fuzz button body is in interference fit with the hole wall of a mounting hole so as to ensure that the fuzz button body has enough fixity in the mounting hole; the short axis of the cross section of the fuzz button body is in clearance fit with the hole wall; enough deformation space is reserved for axial compression of the fuzz button body; when the end surface of the fuzz button body is stressed and compressed, the fuzz button body axially shrinks and slides to a certain degree in the mounting hole; when the stress on theend surface is relieved, the fuzz button body axially extends and slides to a certain degree in the mounting hole and can restore to the natural state; due to the fact that the long axis of the crosssection of the fuzz button body is in interference fit with the hole wall, the fuzz button body cannot fall off from the mounting hole in the natural state; and the fuzz button has the advantages ofbeing simple in fixing mode, few in part and not prone to fall off.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to a fur button which is easy to install and prevents falling off. Background technique [0002] As a special connection element, the fur button body can realize axial elastic compression deformation when it is axially compressed, and then elastically contact with the pressing surface, so it can realize the vertical welding-free interconnection of products between boards. Based on this feature, the fur button body and the fur button body are favored by many users in the electrical field. [0003] At present, there are mainly two application forms for the fur button body. The first one is through-hole loading type, such as figure 1 As shown, the fur button body includes an insulator 2, and the insulator 2 is provided with an installation hole 3 of the fur button body passing through the insulator in the up and down direction, and the fur button body 1 is arranged in ...

AI Technical Summary

Problems solved by technology

However, the above technical solution requires the customer to install the fur button body one by one when using it, that is, this technical solution transfers part of the work to the client when using it. When the number of channels is large, it is extremely inconvenient for the customer to use and affects the customer's sense of use. , when the multi-channel button body needs to be disassembled, it is necessary to remove all the button body 1 one by one, and then remove the insulator 2, which is troublesome

The second type is clamped at both ends, such as figure 2 As shown, the upper and lower ends of the fur button body 1 do not protrude from the upper and lower surfaces of the insulator 2, and an upper fixing cap 7 and a lower fixing cap 8 are respectively arranged at the two ends of the fur button body 1, that is, the fur button body is fixed on the upper surface. The cap 7 (metal hard needle) and the lower fixed cap 8 (metal hard needle) are clamped in the mounting hole 3 on the insulator 2. This method can protect the button body and improve the service life of the button body. However, this technology In the scheme, the number of parts is large, and there are two extra fixing caps in the height direction, resulting in a large space required for installation, which cannot meet the application requirements of low profile
