The structure requirement of the product is met, the thickness dimension of the connector body 11 is greatly reduced, the whole dimension of the earphone connector 1 is reduced, and the requirement of miniaturization of the product dimension is met. Meanwhile, the integral waterproof performance is good, and the waterproof performance of the product is improved.
As shown in fig. 5 to 10, the embodiment of the present invention further provides a manufacturing process of the earphone connector 1, where the earphone connector 1 is the earphone connector 1, and the manufacturing process includes the following steps:
providing a terminal assembly 12, wherein the terminal assembly 12 comprises a plurality of independently arranged terminal units 121, and each terminal unit 121 comprises a welding foot 1211, a contact 1212 and a material tape 1213;
the individual terminal units 121 are allocated as needed to form groups, and the tapes 1213 in the individual terminal units 121 of the same group are stacked. I.e., three terminal units 121 are allocated as a group as needed, and two other terminal units 121 are allocated as a group. Meanwhile, the material tapes 1213 positioned on the same group of the terminal monomers 121 are stacked, so that the position of each terminal monomer 121 before injection molding is positioned. Each tape 1213 is provided with a positioning hole, and positioning is achieved by overlapping and aligning the positioning holes on the tape 1213.
After the terminal units 121 are stacked and arranged as needed, they are put into a mold to be molded, and the connector body 11 is injection molded with the terminal units as inserts. After the terminal units are inlaid and fixed in the connector body 11, a certain distance needs to be formed between the terminal units 121 located on the same side, and the contact head 1212 on each terminal unit 121 extends into the accommodating cavity 110 and is spaced from the bottom of the accommodating cavity 110 by a certain distance, and meanwhile, the soldering leg 1211 on each terminal unit 121 penetrates from the inside of the connector body 11 to have a proper length so as to be capable of being connected with the circuit board 16 in a soldering manner.
After the connector body 11 is formed and the terminal monomers 121 are inlaid and fixed as required by the injection molding production of a mold, the material tape 1213 is cut;
