Elastic contact-pin contact part

Abstract

An elastic contact-pin contact part is composed of a reed contact ring and a contact pin lead foot, wherein the reed contact ring is in a waist drum shape, the middle is protruded outwards, two ends of the contact pin lead foot are respectively provided with a step, a limiting groove is formed between the two steps, and the reed contact ring is sleeved inside the limiting groove between the steps of the contact pin lead foot. The elastic contact-pin contact part is soft to pull and insert, high in strength, capable of being independently used without protection, and wide in application range.

Description

technical field [0001] The invention relates to a contact piece, in particular to a pin contact piece with high reliability, high strength and low insertion force. Background technique [0002] At present, there are many types of contacts used in large quantities, and the combination of rigid pins and elastic jacks (slotted structure, wire spring hole) and the combination of rigid jacks and elastic pins (twist pins) are widely used. These types of contacts have their own advantages and disadvantages: the insertion force of the slotted socket contact is relatively large, and in general, a protective tube needs to be designed to protect the socket; although the wire spring hole has a relatively small and stable separation force, but Its strength is not high, and a protective tube must be designed outside for protection, and the wire spring hole cannot be made too small due to process restrictions, usually it is difficult to realize below 20#; the contact strength of the twist ...

These types of contacts have their own advantages and disadvantages: the insertion force of the slotted socket contact is relatively large, and in general, a protective tube needs to be designed to protect the socket; although the wire spring hole has a relatively small and stable separation force, but Its strength is not high, and a protective tube must be designed outside for protection, and the wire spring hole cannot be made too small due to process restrictions, usually it is difficult to realize below 20#; the contact strength of the twist needle is not high enough, and it cannot be used alone (referring to use It needs to be protected by insulator coating), and similarly, due to the limitation of the process, the twist needle structure contact cannot be processed too large
