A USB based on a Type C

Abstract

The invention provides a USB based on a Type C. The USB comprises a housing, an upper insertion assembly and a lower insertion assembly. The upper insertion assembly comprises an upper insulation body and an upper row of conductive terminals. The lower insertion assembly comprises a lower insulation body, a metal shielding layer and a lower row of conductive terminals. The metal shielding layer and the lower row of conductive terminals are integrally molded. The lower row of conductive terminals comprises lower grounding terminals. Abutting portions of the lower grounding terminals comprise plate-shaped grounding basal bodies and grounding portions formed through projecting downwards from the basal bodies. The grounding portions and the grounding basal bodies are in different planes. The grounding basal bodies are arranged in the lower insulation body. The grounding portions are exposed outside the lower insulation body, and are used for contact with grounding terminals for abutting the USB; and the grounding basal bodies and main body portions of the lower grounding terminals are widened portions. Through adoption of the USB of the invention, the part composition of the product can be reduced; the reliability of the product when heavy currents pass can be raised; and the simplicity can also be raised.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a Type C-based USB connector. Background technique [0002] With the rapid development of science and technology in the electronics industry, electronic products are becoming lighter, thinner and shorter, so the size requirements for electronic components are getting smaller and smaller, and the connector industry is also the first to bear the brunt. The new generation of USB Type C connectors is smaller in size and has higher requirements on mechanical properties and electrical properties. In order to ensure the reliability of products transmitting large currents, major manufacturers have launched corresponding designs. However, due to the small size of the new generation of USB Type C connectors, the large number of terminals, and the limited space, the resistance of the terminals cannot be reduced through the structure. Therefore, the existing common practice is ...

AI Technical Summary

Problems solved by technology

However, due to the small size of the new generation of USB Type C connectors, the large number of terminals, and the limited space, the resistance of the terminals cannot be reduced through the structure. Therefore, the existing common practice is to select a special copper alloy with high conductivity for the terminal material. However, The high cost of the above-mentioned copper alloys leads to a high overall cost of the product
