[0006] Preferably, the upper shell is provided with several labels, and the upper shell has a circular hole for several indicator lights to pass through, and the wire is electrically connected to the PCB board.

[0007] Preferably, each of the connectors includes a connecting machine body, the outer side of which is provided with a guide surface, which is arc-shaped, and a through groove is provided inside the connecting machine body, in which a spring piece is provided.

[0008] Preferably, one end of the spring sheet near the guide surface is connected to the through groove, and the other end is raised towards the inside of the machine body and a limiting block is constructed thereon, which is convex in an arc shape.

[0009] Preferably, each of the adjustment components includes a push block connected to a spring, and a spring is provided at the bottom of the push block, with a sleeve connected to the end of the spring away from the push block.

[0010] Preferably, the spring extends into the bottom end of the sleeve, the sleeve has a threaded groove for the spring to be helically embedded, and the end of the sleeve away from the push block has a long groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a USB data cable hub, which includes a protective mechanism and a hub body. The overall structure is simple and reasonably designed. The hub body includes a PCB board with several connectors symmetrically arranged on it. An indicator light is provided next to each connector on the PCB board. An adjustment component is provided at the bottom of each connector. The bottom of the adjustment component passes through the protective mechanism and is flush with the bottom of the protective mechanism. Each connector includes a connecting body. A guide surface is provided on the outside of the connecting body. The guide surface is arc-shaped, and a through groove is provided inside the connecting body. A spring is provided in the through groove. The guide surface at the opening of the connecting body facilitates the insertion of the USB.

[0012] 2. In this utility model, the adjustment components all include a push block, which is connected to a spring. A spring is provided at the bottom of the push block, and a sleeve is connected to the end of the spring away from the push block. The spring extends into the bottom of the sleeve. A threaded groove is provided in the sleeve for the spring to be spirally embedded, and a long groove is provided at the end of the sleeve away from the push block. After the spring's rebound force weakens due to long-term insertion and removal, the spring pushes the push block, which is connected to the spring, to assist in pushing the spring to contact the USB plug. By rotating the sleeve, the spring is moved out of the sleeve, restoring the spring force between the push block and the sleeve, which facilitates long-term repeated insertion and removal of the USB plug.
