Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a TYPE-C connector. Background Art

[0002] With the rapid development of science and technology in the electronics industry, the size of electronic products is developing along the trend of becoming thinner, lighter and shorter, which requires the size of components of electronic products to become smaller and smaller, and the connector industry is the first to bear the brunt.

[0003] The new generation of Type-C connectors are required to be smaller in size, which leads to higher requirements for mechanical and electrical performance, and makes product design more difficult. In order to ensure product reliability, major manufacturers have launched corresponding structural designs.

[0004] After meeting the requirements of being light, thin, short and small, in order to improve the comprehensive performance of the Type-C connector, other structures will be further added, such as adding EMI shrapnel. After adding the EMI shrapnel, it usually includes a shell, an insulating body, a hook, a terminal module, an EMI shrapnel and other structures. The terminal module is first assembled on the insulating body, the hook is inserted into the insulating body, and then the EMI shrapnel is installed on the insulating body, and finally the shell is installed. Since the terminal module has a large number of terminals, its horizontal size needs to be expanded accordingly, which will increase the size of the EMI shrapnel accordingly. In order to save materials for making EMI springs and ensure that the contact part of the EMI springs to the terminal is avoided, a hollow design is made on the EMI spring corresponding to the terminal slot position of the insulating body. Although it can realize the avoidance design of the EMI spring, it will cause the contact part of the terminal to be relatively exposed in the avoidance hollow of the EMI spring. In this way, during the product insertion process, after the contact part of the terminal contacts the female terminal, the contact part of the terminal will elastically give way and tilt outward. In this way, there is a risk that the contact part of the terminal passes through the avoidance hollow and contacts with the shell to cause a short circuit, resulting in poor product reliability.

[0005] Therefore, it is necessary to develop a new technology to solve the above problems. Utility Model Content
