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] This application uses a USB3.1 Type C plug connector for the front and back insertion of the USB plug. A new type of interface that increases the transfer rate.

[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 two terminal groups 40 on the upper and lower sides of the end, and a positioning protrusion 132 formed on the front edge of the end for the convenience o...

Abstract

The invention provides a USB plug with forward and reverse insertion functions. The USB plug comprises an insulating body, two terminal groups which are respectively installed on the upper side and the lower side of the insulating body, metal buckles inserted to two transverse sides of the insulating body, metal holding members installed at the outer sides of the two terminal groups, and a metal housing arranged outside the insulating body in a sleeving manner. The insulating body comprises a butt joint head part, and a tail part which extends backwards from the butt joint head part. The butt joint head part comprises a hollow butt joint cavity and a plurality of terminal slots penetrating though the upper and down top walls of the butt joint cavity. The tail part comprises a sunken installation part. The terminal groups are vertically installed from the upper side and the lower side of the insulating body. The USB plug with the forward and reverse insertion functions can effectively solve the defect in the prior art that terminal group holding metal buckles lead to unstability.

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...
