Problems solved by technology

The metal fastener includes a shielding part in the middle and elastic arms extending from both sides of the shielding part. The holding of the metal fastener is fixed by the plastic bodies of the upper and lower terminal groups, and the two terminals The cooperating and holding structure of the group and the insulating body is only fixed by inserting the terminal group into the docking cavity of the insulating body from the rear side of the insulating body, and most of the plastic body of the terminal group is still located in the insulating body. At the rear end of the body, the holding effect is not ideal, and the metal fastener is easy to loose due to the stability of the terminal group

Embodiment Construction

[0023] The front and back of this application inserts the USB plug into a USB3.1Type C plug connector. The USB3.1Type C is a USB-IF association developed to reduce the size of the product to meet the needs of handheld mobile devices, and at the same time greatly improve the transmission A new interface with high speed.

[0024] see Figure 1 to Figure 3 As shown, the USB plug of this application includes an insulating body 20, two terminal groups 40 installed on the upper and lower sides of the insulating body 20, and metal fasteners inserted from the side on the lateral sides of the insulating body 20. 50. The metal holders 30 installed on the upper and lower sides of the insulating body 20, the circuit board 13 clamped at the tail of the insulating body 20 to electrically connect the two terminal groups 40, and sleeved on the insulating body 20 The metal shell 10 outside the main body 20.

[0025] The circuit board 13 includes two rows of golden fingers 131 welded to the t...

Abstract

A USB plug with positive and negative insertion, comprising an insulating body, two terminal groups respectively installed on the upper and lower sides of the insulating body, metal fasteners inserted on both lateral sides of the insulating body, and mounted on the two terminals A metal holder on the outside of the set, and a metal shell sleeved outside the insulating body, the insulating body includes a butt joint part and a tail part extending backward from the butt joint part, and the butt joint part includes a hollow The formed docking cavity, several terminal slots passing through the upper and lower top walls of the docking cavity, the tail part includes a mounting part formed by a depression, and the terminal group is installed from the upper and lower sides of the insulating body in the vertical direction; this The application can effectively solve the defect in the prior art that the terminal group is not stable due to the holding of the metal fastener.

Description

technical field [0001] The present application relates to the field of electrical connectors, in particular to a reversible USB plug. Background technique [0002] The Universal Serial Bus (USB) widely exists in people's daily life, and most electronic equipment data transmission adopts this common standard; the emergence of the USB3.0 standard has greatly improved the data transmission speed, in the standard A Type In terms of USB interface design, USB3.0 can perfectly implement design changes without affecting backward compatibility and structural appearance. However, in the Micro USB field of mobile terminal applications, it is impossible to achieve functional upgrades while ensuring that the structural appearance remains unchanged. The Micro USB 3.0 standard eventually complicates the appearance and structure, that is, an interface is added in a side-by-side manner to accommodate the increased functional solder pins. , but takes up more space, limited to the development...
