USB connector based on TypeC

Abstract

The invention provides a USB connector based on TypeC. The USB connector comprises a housing and plug-in assemblies. The plug-in assemblies comprise an insulating body and a row of conductive terminals which are integrated with the insulating body. The conductive terminals comprise a first grounding terminal, a first power terminal, a signal terminal, a second power terminal, and a second grounding terminal. The USB connector is formed by two components of the housing and the plug-in assemblies, and product assembly is simple, providing convenience for automation production. The product structure is reliable, and quality is stable. The plug-in assemblies comprise the insulating body and the row of conductive terminals. The row of conductive terminals are formed in a one-time manner in an injection molding process. In an assembly process, weld legs are cut off and a housing is installed, so product coplanarity is easy to ensure. The row of conductive terminals comprise the first grounding terminal, the first power terminal, the signal terminal, the second power terminal, and the second grounding terminal, and the above terminals can be made by a same metal strip through a sheet metal forming technology, so that the number of dies is saved, and production cost is reduced.

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 better mechanical and electrical requirements. In order to ensure the reliability of products transmitting large currents, major manufacturers have launched corresponding designs. [0003] The main structure of the existing USB Type C connector is fastened by two-piece insert components, followed by secondary injection molding, or directly buckled by two insert components. However, the connector with this structure is composed of three parts includi...

AI Technical Summary

Problems solved by technology

However, the connector with this structure is composed of three parts: the housing, the upper insertion assembly, and the lower insertion assembly, and the assembly is complicated and the cost is high.

Moreover, multiple parts are used for assembly, resulting in reduced product reliability

[0004] Moreover, due to the small size of the new generation of USB Type C connectors, the large number of terminals, and the limited space, it is impossible to reduce the resistance of the terminals through the structure

In order to ensure the reliability of the product to transmit large currents, the existing common practice is to select special copper alloys with high conductivity for terminal materials. However, the cost of the above-mentioned copper alloys is high, resulting in a high overall cost of the product.
