Electric connector and manufacturing method thereof

Abstract

The invention provides an electric connector comprising an insulated seat body, at least one connecting portion, and at least one terminal. The at least one connecting portion is arranged at one end of the insulated seat body. The at least one terminal is arranged at a plastic seat body; a board plane and a punching plane are arranged at the outer surface of the terminal; the board plane of the terminal is provided with an extending portion, a fixed portion and a connecting pin by punching and bending in an integrated mode and an electroplating layer is arranged at the outer surface; the fixed portion and the insulated seat body are fixed; the extending portion is connected to one end of the fixed portion and is provided with a contact portion that is arranged at the connecting portion; and the connecting pin is connected to one end of the fixed portion and extends out of the insulated seat body, wherein the board plane of the fixed portion is wider than that board plane of the connecting pin. The electric connector is characterized in that at least one side of one end, connected to the connecting pin, of the fixed portion of the terminal is provided with a first electroplating layer-free fracture surface; and the terminal is also provided with at least another electroplating layer-free fracture surface beside the first electroplating layer-free fracture surface.

Description

technical field [0001] The present invention relates to an electrical connector and a manufacturing method thereof, in particular to an electrical connector with convenient and efficient terminal manufacturing. Background technique [0002] The terminal manufacturing and assembly of the first type of conventional electrical connector are roughly as follows: [0003] 1. Continuous punching die punching and bending station--The regular metal sheet material (whole volume of high-density and high-capacity packaging) enters the stamping continuous die, and is punched and bent at one time to form a continuous sheet connected to a material belt. Arrangement of terminals, after punching and bending, the terminals have become protruding or bent and are not regular sheet structures, so the upper and lower terminals need to be separated by paper tapes when they are rolled into rolls, so that the terminals and roll paper tapes are easy to Anomalies caused by strain (1 time), and the or...

Problems solved by technology

[0003] 1. Continuous punching die punching and bending station--The regular metal sheet material (whole volume of high-density and high-capacity packaging) enters the stamping continuous die, and is punched and bent at one time to form a continuous sheet connected to a material belt. Arrangement of terminals, after punching and bending, the terminals have become protruding or bent and are not regular sheet structures, so the upper and lower terminals need to be separated by paper tapes when they are rolled into rolls, so that the terminals and roll paper tapes are easy to Anomalies caused by strain (1 time), and the original roll of high-capacity, high-density metal sheet is formed by stamping and bending, and the continuous terminals are bent and protruded, so it becomes a low-density winding material, so it needs to be divided into multiple rolls, and the low density Cause high turnover and low operating efficiency

[0004] 2. Continuous electroplating station--The irregular continuous terminals that have been bent and formed are likely to cause abnormal strains during the electroplating process (twice). (3 times)

[0005] 3. Automatic assembly station--formed and electroplated terminals (irregularly bent and formed terminals, which are made after many times of winding material turnover and processing, are likely to cause repeated strain abnormalities), and the yield rate is not good. The assembly of stable terminals and plastic seat body is easy to cause product defects

[0009] 2. Continuous electroplating station--The terminal after punching, bending and forming directly enters the continuous electroplating process, and the irregular terminal after bending and forming is easy to cause abnormal strain during the electroplating process (1 time)

[0010] 3. Automatic assembly station - terminals that have been formed and electroplated (irregularly bent and formed terminals, after electroplating processing, are likely to cause abnormal strain), and terminals with unstable yields are easily assembled with plastic seats. product defect

[0016] Although the third type avoids the consistent operation risk of electroplating processing, there is still the risk of consistent operation of the die punching and bending station and the automatic assembly station, and all the punched surfaces of the terminal are without electroplating, which is very bad, so the third method unrealistic
