TypeC-based USB connector capable of transmitting heavy current

Abstract

The invention provides a TypeC-based USB connector capable of transmitting heavy currents. A butt joint portion of a lower grounding terminal includes a grounding base body and a plate-shaped grounding portion that protrudes downwardly from the grounding base body. The grounding portion and the grounding base body are in different planes. The grounding base body is disposed inside a lower insulation body, and the grounding portion is exposed from the lower insulation body. A butt joint portion of a lower power signal terminal includes a power signal base body and a plate-shaped power signal portion that protrudes downwardly from the power signal base body. The power signal portion and the power signal base body are in different planes. The power signal base body is disposed inside the lower insulation body, and the power signal portion is exposed from the lower insulation body. The grounding base body of the lower grounding terminal, the power signal base body of the lower power signal terminal, a main body portion of the lower grounding terminal and a main body portion of the lower power signal terminal are all widened portions. Through adoption of the TypeC-based USB connector, the reliability and simplification of heavy currents passing across a product can be improved.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a USB connector based on Type C capable of transmitting large current. 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 better mechanical and electrical requirements. 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 com...

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
