Problems solved by technology

[0004] The cross-section types of the above-mentioned existing contact fingers are all elliptical, and the disadvantages are: 1) the deformation range is small, the diameter range of the applicable contact finger (conductive column) is narrow, and the allowable tolerance is relatively strict, which makes the manufacture of the contact finger spring more difficult. 2) When the finger spring is installed in the cavity, it cannot be clamped tightly, and it is easy to fall off, which affects the performance and quality of the product. The technical problem to be solved by the present invention is to provide a triangular finger spring

Embodiment Construction

[0018] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0019] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to t...

Abstract

The invention discloses a triangular button contact spring. The cross section of the spring is triangular. According to the triangular button contact spring provided by the invention, the force-bearing section adopts a triangle which is different from an ellipse of similar products, the deformation range of the spring is greatly enlarged, and then the triangular button contact spring can be used for conductive button contacts with different sizes; and meanwhile, the triangular spring adopts two-angle supporting, the principle of triangular stability is utilized very well, and thus the triangular button contact spring can be firmly clamped in a cavity groove and not prone to falling off.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to a triangular finger spring. Background technique [0002] In the high-voltage electrical industry, it is generally used to fasten the petal-shaped contact fingers with a ring-shaped spring. The holding force of the contact finger spring is an important guarantee for the close contact between the petal-shaped contact fingers and the conductor. When installing the finger spring on the conductive recess of the petal-shaped finger, it is necessary to stretch the finger spring before installing, but in order to ensure the holding force of the finger spring, the stretching allowance of the spring will not be too large , which makes the assembly of the finger spring more complicated. [0003] The cross-section types of the existing contact fingers are all elliptical, and the disadvantages are: 1) the deformation range is small, the diameter range of the applicable contact finger (condu...
