Description

Technical Field

[0001] The utility model relates to the technology in the field of Type-C connectors, and in particular to a pad-type Type-C connector. Background Art

[0002] Type-C is much smaller than Type-A and Type-B, and is a new type of USB interface with a thin and compact interface. In addition, Type-C is an interface type that can be applied to both PCs (master devices) and external devices (slave devices, such as mobile phones), and has good practicality; and Type-C supports higher power transmission, up to 100W, and the fastest data transmission speed is up to 10Gbps, supporting more high-power load devices; and Type-C is the latest USB interface appearance standard. This interface has no difference in forward and reverse directions, can be plugged in and out at will, and is more flexible in application. Type-C connectors have many specifications, including 6Pin, 12Pin, 16Pin, 24Pin and other structures.

[0003] The current pad-type Type-C connector generally has a structure in which multiple terminals are embedded in an insulating body, a shielding inner shell is covered on the outside of the tongue plate, and a shielding outer shell is covered on the outside of the shielding inner shell (the shielding outer shell mainly plays a padding role). When assembling a Type-C connector with this structure, multiple spot welding is required between the shielding inner shell and the shielding outer shell, and multiple buckling structures are provided on the shielding inner shell and the shielding outer shell. The production steps are many and the operation is complicated. The production efficiency is very low, which brings inconvenience to production. The production cost of the product is high and it is not very competitive; some will be designed as a structure with a shielding shell to pad, such as Figure 7 As shown, the sheet-shaped shielding shell 30' is bent and riveted to form a receiving cavity and a downwardly extending fixed foot 33'. However, since the fixed foot 33' is formed by piercing the shielding shell 30', the length of the fixed foot 33' is affected by the length of the shielding shell 30', resulting in the length of the fixed foot 33' being limited and cannot be set too long, which cannot meet the existing needs. Therefore, it is necessary to study a new technical solution to improve the current pad-type Type-C connector. Utility Model Content
