Embodiment Construction

[0031] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0032] 1. An embodiment

[0033] figure 1 is a diagram of an electrical contact terminal 100 according to one embodiment of the present invention.

[0034] refer to figure 1 , the elastic electrical contact terminal 100 includes a tubular insulating elastic core 10 , an insulating non-foam rubber coating layer 20 , and a heat-resistant polymer film 30 with a metal layer 40 on the surface stacked in sequence.

[0035] In this structure, a tubular elastic core manufactured by an extrusion process is applied, thereby reducing manufacturing cost, adjusting elastic force and pressing force to control the size of the through hole of the tube and efficiently manufacturing small products. In addition, the insulating non-foam rubber coating maintains adhesion and resiliency before and after the welding process and during repeated compression tests. I...

Abstract

Provided is a solderable elastic electric contact terminal. The elastic electric contact terminal includes an insulating elastic core including a non-foam rubber having a tube shape, an insulating non-foam rubber coating layer adhered to the insulating elastic core such that the insulating non-foam rubber coating layer encloses the insulating elastic core, and a heat resistant polymer film having one side adhered to the insulating non-foam rubber coating layer such that the heat resistant polymer film encloses the insulating non-foam rubber coating layer and another side on which a metal layer is integrally formed.

Description

technical field [0001] The present invention relates to an electrical contact terminal, in particular, to an elastic electrical contact terminal suitable for performing a soldering process on the elastic electrical contact terminal while electrically and mechanically connecting a target to a printed circuit board. More particularly, the present invention relates to an elastic electrical contact terminal suitable for performing a reflow soldering process on the elastic electrical contact terminal using a surface mount process. Background technique [0002] In general, solderable elastic electrical contact terminals must have high electrical conductivity and excellent elastic recoil and must withstand soldering temperatures. [0003] Related art reflow solderable electrical contact terminals are mainly formed of metal. In particular, beryllium copper is widely used for electrical contact terminals because beryllium copper has excellent elastic resilience and high electrical c...
