Electric connector and assembly method thereof

Abstract

The invention discloses an electric connector and an assembly method thereof, and the electric connector comprises an insulating body, a first terminal, a second terminal and a metal housing, wherein the insulating body comprises a base and a tongue plate, a through hole is arranged on the tongue plate, a first terminal groove and a fixing groove are arranged on the upper surface of the tongue plate, and a second terminal groove is arranged on the lower surface of the tongue plate; the first terminal and the second terminal are correspondingly inserted in the first terminal groove and the second terminal groove respectively; the contact part of the second terminal penetrates through the through hole upwards from the lower surface of the tongue plate and is further embedded in the fixing groove; and the metal housing is wrapped outside the insulating body. Therefore, by inserting and arranging the first terminal and the second terminal on the insulating body and utilizing the contact part of the second terminal to penetrate through the through hole upwards from the lower surface of the tongue plate and be embedded in the fixing groove, the process steps can be saved, the assembly is ensured to be simple, work stations are less, the labor cost is reduced, the second terminal is ensured to be away from the first terminal, the short-circuit risk can be avoided, and the qualification rate of products can be greatly improved.

Description

Technical field [0001] The present invention relates to the field of electrical connector technology, in particular to a USB3.0 electrical connector which saves manufacturing process and has a simple structure and an assembly method thereof. Background technique [0002] Universal Serial Bus (USB) is a hot-swappable transmission interface widely used in personal computer peripheral products. The interface is connected to the hardware for data transmission without rebooting. With good performance characteristics, the first generation of USB 1.1 transmission interface was introduced in 1988, and in 2000 Intel published the official specification of USB2.0, which also expanded the types of computer peripheral products that can use the USB transmission interface, such as mobile hard disks. , Printer, mouse, etc. [0003] However, as the file capacity to be transferred is increasing day by day, the transfer speed of USB2.0 is limited by the control chip and various factors, which can n...
