Description

Technical Field

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

[0002] Type-C is significantly smaller than both Type-A and Type-B, making it a new type of slim and compact 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 waterproof Type-C connectors typically have multiple terminals mounted on an insulating body, with a plastic shell encasing the insulating body, and a metal shell encasing the plastic shell. The plastic shell extends outwards with a latching section featuring positioning holes. This latching section is used to engage with external components for a secure connection, making the connector more robust. While this structure is simple, the latching section lacks structural strength. During use, vibration or impact can easily cause deformation or even breakage, leading to connector detachment and disruption of equipment operation. This poses significant safety hazards, results in poor product quality, a short lifespan, and a subpar user experience, failing to meet current needs. Therefore, it is necessary to research a new technical solution to improve current waterproof Type-C connectors. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a structurally enhanced waterproof Type-C connector. This effectively solves the problems of insufficient structural strength of the ear loop portion of existing waterproof Type-C connectors. When subjected to vibration or external impact during use, the ear loop portion is easily deformed or even broken, causing the connector to loosen and become unsecured, affecting the normal operation of the equipment, posing a significant safety hazard, resulting in poor product quality, short service life, and poor user experience.
