  • Publication number: 20230208090
    Abstract: A method of manufacturing an electric connector includes: providing a metal strip and stamping on the metal strip at a stamping station to obtain a terminal set; packaging and conveying the terminal set to an electroplating station; electroplating and conveying the terminal set to an assembling station; bending and assembling the terminal set into the insulator. The bending operation of the terminal set is transferred to be carried out on the assembling station after the electroplating operation, and is prevented from being carried out at the stamping station. On the one hand, the structure of the terminal set can be kept flat after stamping, which can improve the packaging efficiency and the packaging quantity. On the other hand, the relatively flat structure of the terminal set is more conducive to electroplating treatment, which can improve the electroplating quality and prevent the terminal from deforming.

  • Publication number: 20230087812
    Abstract: An electric connecting device includes an insulator with a front end abutting surface and a rear end mounting surface, a terminal module and a USB plugging module in the insulator. A first plugging cavity and a second plugging cavity distributed in a horizontal direction and a guide hole between them are arranged in the insulator. The first plugging cavity and the second plugging cavity forwardly penetrate through the front end abutting surface and form a round interface and a USB interface respectively. By simultaneously providing the two plugging cavities on the insulator, two different plugging functions can be satisfied. The transmission of a DC power supply and the transmission of a USB signal are realized at the same time. The integrated structure can reduce the occupation of a circuit board space and the assembly cost of the product.

  • Patent number: 9997870
    Abstract: The present invention relates to an electrical connector, which has an insulation body, a shielding plate, a plurality of grounding terminals and conducting terminals accommodated in the insulation body. Each grounding terminal is formed by bending a linear wire and has an upper contacting portion, a bending portion extending from the upper contacting portion, and a lower contacting portion extending from the bending portion, wherein the upper contacting portion is parallel to the lower contacting portion. Therefore, the crosstalk between the upper-row signal terminals and the lower-row signal terminals is reduced, and the shielding effect is enhanced.

  • Patent number: 9325125
    Abstract: An electrical connector includes an insulating housing and a plurality of contacts retained on a mating portion of the housing. The mating portion has a mating port with a geometric centre. The contacts are divided into an upper array and a lower array. Each array includes several first contacts and at least one pair of second contacts located on two sides of the first contacts, the first contacts of the upper array are centrally symmetric to the first contacts of the lower array relative to the geometric centre of the mating port. The new type of contacts arrangement can improve the quality of the signal transmission.

  • Patent number: 9325115
    Abstract: An electrical connector includes an insulative housing, a plurality of terminals retained in the insulative housing. The insulative housing has a receiving room and a mating part received in the receiving room, the mating part defines a mating hole and a pair of receiving grooves extending rearward on two lateral sides of the mating hole. The terminals include a detecting terminal received in the mating hole and a pair of power terminals received in the receiving grooves. The mating part further defines a pair of guiding surfaces on two sides of the mating hole and a pair of stiffening ribs on two sides of the receiving groove, which can reduce the mating force during the mating process and protect the mating part.
