Positive-negative insertion USB socket

Abstract

The invention relates to a positive-negative insertion USB socket. The positive-negative insertion USB socket comprises an abutting joint piece and a metal shell, wherein the metal shell is sleeved outside the abutting joint piece, and an inserting and connecting space is formed by the metal shell and the abutting joint piece; the abutting joint piece comprises a first terminal group, a second terminal group, an isolation middle plate, an insulating body and a grounding piece, the isolation middle plate is clamped between the first terminal group and the second terminal group, the insulating body is used for forming the first terminal group and the second terminal group into one body in the isolation middle plate; the abutting joint piece is provided with a base pat, an abutting joint tongue part positioned inside the inserting and connecting space and a step part for connecting the tongue part and the base part; the grounding piece is sleeved on the periphery of the step part; the isolation middle part, on two sides of the position of the step part, is provided with spot welding parts in contact with the inner side surface of the grounding piece; and the spot welding parts are clamped with the grounding piece through spot welding into one body. According to the positive-negative insertion USB socket, the integrated consistency of the product can be effectively improved.

Description

technical field [0001] This application relates to the field of electrical connectors, in particular to a reversible USB socket. 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 terms of USB interface design, USB3.0 can perfectly implement design changes without affecting backward compatibility and structural appearance. However, in the MicroUSB field of mobile terminal applications, it is impossible to achieve functional upgrades while ensuring that the structural appearance remains unchanged. The MicroUSB3.0 standard eventually complicates the appearance structure, that is, an interface is added in a side-by-side manner to accommodate the increased functional solder pins. However, it takes up more space and is limited to the development trend of ultra-thin sm...

Problems solved by technology

However, in the MicroUSB field of mobile terminal applications, it is impossible to achieve functional upgrades while ensuring that the structural appearance remains unchanged. The MicroUSB3.0 standard eventually complicates the appearance structure, that is, an interface is added in a side-by-side manner to accommodate the increased functional solder pins. However, it takes up more space and is limited to the development trend of ultra-thin smartphones, which greatly limits the application of MicroUSB3.0 on mobile phones. A new high-speed serial universal bus is urgently needed to solve this problem.

[0003] In this case, the USB Association has launched a new USB3.1 Type C interface connector, which takes into account both size and performance, and is suitable for applications on smart terminals, but it is not backward compatible

However, the size of this product is small, and the number of pins is large, so that the butt joint of the connector base needs to bear a very large pressure during the insertion process. The middle of the butt joint is integrally formed with a metal partition. The strength of the metal partition is generally digested by the metal partition, and the bearing capacity of the metal partition is still limited. Larger forces are likely to cause adverse effects such as deformation of the metal partition and displacement of the butt joint.
