Description

Technical Field

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

[0002] Connectors, also known as connectors, plugs and sockets in China, generally refer to electrical connectors. That is, devices that connect two active devices to transmit current or signals. Connectors are a component that our electronic engineering technicians often come into contact with. Among them, USB Type-C is a new USB interface form. It is a new interface developed by the USB standardization organization to solve the long-term shortcomings of USB interfaces such as inconsistent physical interface specifications and one-way transmission of electrical energy. It integrates charging, display, data transmission and other functions.

[0003] In order to enhance the strength of the shielding shell of the existing Type-C connector, the shielding shell is usually formed by assembling the inner shell and the outer shell together. Although this method can improve the strength of the shielding shell, the inner shell and the outer shell are only fixed by spot welding, which may cause the problem of cold welding, and the inner shell is easy to fall off. In addition, the spliced ​​structure of the inner shell and the outer shell needs to be placed outside the insulating seat during assembly, which is not easy to align, and the manufacturing and assembly are quite troublesome and inconvenient;

[0004] Secondly, since there is no stable fixing and combination structure between the insulating seat and the shielding shell, it is easy for the insulating seat and the external electrical connector to become loose due to external force pushing and pulling on the insulating seat after multiple plugging and unplugging; the overall structure has poor stability.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
