Method for mfg. connectors

Abstract

A manufacturing method for an electric connector includes: forming an insulation body having an outside face, multiple terminal holes through the body designed close to the outside face, forming multiple conduction terminals having a hold part fixing the terminals on the body, in which, at least a recess is set on the hold part, plugging the said terminals into the insulation body and plugging the hold part into the terminal hole and punching the outside face which is corresponding to the hold part of the terminals so as to enable the insulation body to turn concaved to form a proud in the recess part.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of an electrical connector, in particular to a manufacturing method of an electrical connector capable of strengthening the holding force between an electrical connector terminal and an insulating body. 【Background technique】 [0002] It is well known in the industry that with the development of electrical connectors in the direction of miniaturization, high speed and stability, the insulating body and conductive terminals of electrical connectors are also developing in the direction of miniature and high density, which increases the difficulty of matching the electrical connector with its connected components. When the conductive terminal and the insulating body are not firmly fixed, it is easy to cause the terminal to loosen. Therefore, the industry uses a process of stamping the insulating body to plastically deform it to strengthen the terminal holding process, that is, stamping the insulating body ...

AI Technical Summary

Problems solved by technology

However, because the thickness of the terminal 70 is small, usually 0.30mm, the diameter of the bump 7211 is usually no more than 0.6mm, and when punching the bump 7211, a concave hole 7222 of similar size will be formed on the second holding surface 722, so If the diameter of the bump 7211 is too large, its strength will be weak. When the insulating body 60 is stamped, the concave plastic due to plastic deformation pushes against the bump 7211, which will easily cause the bump 7211 to recover and deform, thereby making the terminal 70 The interference effect between the holding part 72 and the terminal hole 65 is not good

The width of the terminal 70 is usually more than 1.5 mm, which is much larger than the diameter of the bump 7211 of 0.6 mm. When punching the insulating body 60, it is necessary to press a larger area on the first mating surface 651 to the first holding surface 721, so for A certain stamping depth S1 (such as Figure 7 As shown), the amount of interference S2 generated by it is small, and the diameter of the bump 7211 is small, and the area where the pressed first mating surface 651 directly interferes with the bump 7211 is also small, and it can only be used with the plastic inner Part of the material is concave and deformed, and it is easy to deform the first mating surface 651 that interacts with the bump 7211, so that its holding effect is not good
