Abstract

The present invention is related to a conducting terminal of electric connector and its manufacturing method. At first, the bar-shape metal is punched and cut to form the prototype of conducting body.

The plastic bending face, which is fixed on the main-body of the electric connector, is used to replace the other end of the conducting terminal; and the electric connector is undergone with an ejection molding process so as to form the protruding points at the same time.

Description

1221685 V. Description of the invention (l) [Technical field to which the invention belongs] The present invention relates to a conductive terminal of an electrical connector and a manufacturing method thereof, and particularly to a conductive terminal on an electrical connector having only a single-sided conductive end. It is more simplified, reduces the defective rate and the production cost, and can be widely used in computer chip assembly by this technical means, so that the conductive end of the electrical connector = pushed by an eccentric rocker, and can have better electrical contact with the circuit board To improve product quality and computer stability. [Previous technology] Therefore, when the strip material is extended and punched with electricity, that is, when the conductive terminal is put into the terminal, the computer will easily turn on. At the same time, because the conductive terminal is inserted, there is no way to be correct The soldering of each conductive terminal has passed through the process of adding multiple conductive conductive terminal structures, resulting in high production costs and high production efficiency. It cannot occupy an advantageous position. The current, electrical conductivity of the known electrical connectors The conductive body punched at the end, and the two sides of the conductive body face the corresponding conductive ends corresponding to the connection part of the board. There are two more conductive feet. According to this structure, the electrical contact with the circuit board is poor (conductivity), so the two feet that are unstable or use the main factor of IF crashes are flexible. Into the body of the electrical connector; j :: The contact end of the board still needs to be densely tinned. However, the field of electrical connectors is so familiar that the required manpower and material resources are higher, because: ϊ ί The rate of defective products is always high, and in-progress is the current example of the industry, and the 'Γ1 industry's double-simple dance [the problem facing the industry is facing. The purpose of the present invention is to provide a conductive terminal of an electrical connector with good electrical contact and good fixing effect. It is because the conductive terminal has only one conductive end, and the conductive end is replaced with plastic fixed to the electrical connector body. Therefore, an excellent fixing effect is obtained, and the conductive terminal and the plastic are at the same time. A good clamping force is generated, so that the conductive terminals of the electrical connector can have good electrical contact with the circuit board when pushed through the rocker. # Therefore, the conductive terminal of the electrical connector of the present invention has the advantages of inter-structure, good fixing effect, convenient soldering, and good contact conductivity.
