Description

Technical Field

[0001] This utility model relates to the field of Type C connectors, and in particular to a new type of Type C connector. Background Technology

[0002] Type-C is significantly smaller than both Type-A and Type-B, making it a slim and compact new type of USB interface. Furthermore, Type-C is an interface type that can be used with both PCs (host devices) and external devices (slave devices, such as mobile phones), offering good practicality. Type-C also supports higher power transmission, up to 100W, with the fastest data transfer speeds reaching 10Gbps, supporting a wider range of high-power devices. Finally, Type-C is the latest USB interface form factor standard; this interface has no reversible orientation, allowing for easy plugging and unplugging, thus increasing application flexibility. Type-C connectors come in various specifications, including 6-pin, 12-pin, 16-pin, and 24-pin designs.

[0003] Current Type-C connectors generally consist of an upper insulating component, a lower insulating component, an outer insulating component, upper terminals, and lower terminals. During production, multiple upper terminals are placed into a mold to injection mold the upper insulating component, multiple lower terminals are placed into another mold to injection mold the lower insulating component, and then the upper and lower insulating components are stacked and placed into yet another mold to injection mold the outer insulating component. This Type-C connector structure is relatively simple, and although it can basically achieve the data transmission function of a connector, this product has many production steps, is cumbersome, and has a long production cycle, causing inconvenience to production. The multiple injection molding processes require multiple sets of injection molds, resulting in high production costs and making the product less competitive and unable to meet current needs. Therefore, it is necessary to research a new technical solution to improve the current Type-C connector. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel Type-C connector includes a positioning element, an insulating body, upper terminals, lower terminals, and a shielding shell. The upper surface of the positioning element has multiple upper positioning grooves, with upper limit blocks on both sides of each groove.

[0013] As a preferred embodiment, an adhesive groove is formed on the outer rear side of the base. The adhesive groove is filled with waterproof adhesive to form a waterproof component. The multiple upper terminals and multiple lower terminals are embedded and fixed together with the waterproof component, which effectively enhances the waterproof performance of the product.
