Description

Technical Field

[0001] This utility model relates to the field of USB interface technology, specifically to a side-mounted USB interface with shielding function. Background Technology

[0002] Electronic products can interfere with other electronic products in the vicinity. This interference can be conducted or radiated, collectively known as electromagnetic interference (EMI). EMI signals can cause crosstalk to equipment or testing instruments. USB 3.0 is one of the main interfaces for connecting electronic devices, and external electronic products can also cause signal crosstalk to the USB port. The co-channel interference between USB 3.0 and 2.4GHz Wi-Fi is particularly severe.

[0003] To address this, we propose a side-mounted USB interface with shielding functionality. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a side-mounted USB interface with shielding function.

The side-standing female connector body includes a core, several terminals embedded in the core, and a shell sleeved on the outside of the core. The shell has solder feet extending downwards on both sides. The shielding shell includes an upper shielding shell and a lower shielding shell. The upper shielding shell is sleeved on the outside of the shell, and the lower shielding shell is fastened to the lower side of the upper shielding shell from bottom to top. By fastening the upper shielding shell and the lower shielding shell together, the product is fully enclosed, shielding external signals and preventing signal interference problems when the electronic product is working.

[0006] As a preferred embodiment of the present invention, the upper shielding shell includes a side cover sleeved on the outside of the shell, and a rear cover is connected to the rear end of the side cover.
