Background

Data interfaces are usually provided on electronic devices, and the electronic devices can be connected with other external devices through tongues provided in the data interfaces. The tongue piece in the data interface can not only charge the electronic equipment, but also realize the data transmission function between the electronic equipment and other external equipment such as a Personal Computer (PC). The data interface on the electronic device, taking the currently more commonly used Type-C interface as an example, is usually disposed on the frame of the device. In practice, however, the position of the data interface on the device frame is mainly influenced by the position of the tongue mounting.

In the related art, the tongue pieces in the data interface are mostly of a solder plate type structure, and are fixed on the circuit board of the electronic device by soldering, so the layout position of the data interface on the frame can be determined by the height of the circuit board inside the electronic device, while the existing data interface usually shows an eccentric position on one side of the frame of the device, as shown in fig. 4. Moreover, the tongue piece is usually wrapped by a casing to support and protect the tongue piece and assist in positioning the data interface. However, a certain gap is formed between the shell outside the tongue piece and the tongue piece, and the thickness of the position generally determines the thickness of the whole machine; moreover, the existence of the gap and the exposure of the data interface easily cause the inflow of external moisture through the data interface and the gap to damage the circuit board and electronic components on the circuit board, so that an additional waterproof material (such as a silica gel ring) is required to be matched with the shell.
