Female terminal of electric connector and processing method of female terminal

Abstract

The invention discloses a female terminal of an electric connector and a processing method of the female terminal. The female terminal comprises a cylindrical main body, a lining and an outer sleeve, wherein the main body is made of a conductive material and comprises a first end, a second end and a contact part; the contact part is a cylinder formed by rolling a parallelogram into a circle and is provided with at least two annular curve surfaces which protrude towards an enclosed hollow cavity; the first end and the second end extend along two axial ends of the contact part separately; the contact part is arranged in the lining and the first end and the second end are folded outwards to fix the lining; and at least one outer sleeve sleeves the outside of the lining. The nearly double contact area is formed by a W-shaped staggered structure for conduction and a wave-shaped double-blade and double-curved surface feature terminal, so that the target that one socket is matched with two jacks can be achieved; the contact resistance is reduced, the insertion and extraction force is more stable and the insertion and extraction life is longer; high reliability of electric contact can be kept in a strong vibration shock environment; and the current-carrying capability is higher under the conditions of fixed contact pressure and raw materials.

Description

technical field [0001] The invention relates to a female terminal of an electrical connector and a processing method thereof, in particular to a connecting terminal for electrical connection. Background technique [0002] Electrical connector female terminal (also known as electrical connection jack) is a product used to realize electrical connection, which is widely used in the electronics industry. In order to realize high current connection, torsion spring terminals are generally used. The existing elastic reeds only have a set of parallel grids at a certain angle, so the contact area between the elastic reeds and the connecting pins is small, and the contact surfaces are concentrated in the middle of the cylindrical axis. Therefore, only one pin can be matched with one socket, which cannot meet the needs of some special cases. [0003] The contact surface of existing connectors is generally a single leaf hyperboloid structure with a small contact area, and after the te...

Problems solved by technology

Therefore, only one pin can be matched with one socket, which cannot meet the needs of some special cases.

[0003] The contact surface of the existing connector is generally a single leaf hyperboloid structure, the contact area is small, and if the contact positive pressure, contact area and other parameters are adjusted later after the terminal is manufactured, it is not easy to adjust, and the mold needs to be re-opened

[0004] In addition, the smallest part of the existing terminal reed is easy to yield during multiple plugging and unplugging processes, resulting in unstable plugging force and unable to obtain a higher life due to its structural limitations

In order to obtain a larger contact area, the current elastic reed terminal of the connector needs to be manually twisted during the production process, which makes the manufacturing process complicated, and the product is easily deformed and damaged, and it is difficult to repair, which leads to high manufacturing and labor costs.
