Electrical connector terminal and reel carrier using same

Abstract

Disclosed is an electrical connector terminal mounted on a conductive pattern of a metal case or a circuit board. The size of an adhesive tape adhered to a lower surface of a body is smaller than thesize of the body so that an edge of the adhesive tape is positioned inward from an edge of the body to form a margin portion on the lower surface of the body, in the margin portion the body and an object are melted to each other by welding to form a welding layer between the lower surface of the body and a surface of the object, and the connector terminal and the object are mechanically and electrically connected by the welding layer.

Description

technical field [0001] The invention relates to an electrical connection terminal, in particular to an electrical connection terminal mounted on a metal casing or a conductive pattern on a circuit substrate. Background technique [0002] In electronic communication equipment including cellular phones, electrical connection between a circuit substrate and a metal case is essential for various purposes. [0003] Usually, in order to realize the electrical connection between them, an elastic metal clip is used, and the metal clip can be mounted on the conductive pattern of the circuit substrate or installed on the metal casing. [0004] First, when the metal clip is attached to the conductive pattern of the circuit board, the metal clip elastically presses the surface of the metal case and contacts the metal case. [0005] The metal shell is made of light weight and high strength aluminum or aluminum alloy or magnesium and other metal materials and non-ferrous metals of their ...

AI Technical Summary

Problems solved by technology

[0010] As a result, the metal clip that is in contact with the upper surface of the electrical connection terminal comes into contact with the solder, thereby reducing the conductivity, and not only that, but also comes into contact with the solder with a lower hardness, resulting in a reduction in the reliability of the electrical contact

[0011] In addition, soldering cannot be performed in a metal case made of nonferrous metal, so instead of soldering, the electrical connection terminal can be mounted with an adhesive tape, but it needs to be done manually from the adhesive tape supplied with the release paper After peeling off the release paper, it is attached to the metal case, so the work efficiency is reduced

Conversely, if the release paper is not attached, the adhesive tape will be contaminated with foreign matter, or the adhesive tape will be attached to other objects during transfer, so the adhesive force may decrease
