[0002] With the trend of digitalization and miniaturization of electronic and communication equipment, in order to avoid electromagnetic waves generated by electromagnetic wave sources and prevent interference from peripheral equipment, and to solve the problem of harmfulness of electromagnetic waves to human body, a shielded wire grounding system has been created. The main function of the shielded wire grounding system is to reduce or eliminate electromagnetic interference, protect signal lines from the influence of external electromagnetic fields, and also prevent electromagnetic interference of signal lines to the external environment. The shielding layer is usually made of conductive materials, such as copper or aluminum. It surrounds the signal line and can effectively guide the interference current into the earth through grounding, thereby achieving a shielding effect. The connection of the shielding wire may become loose due to vibration or impact of the equipment, thereby affecting the shielding effect. In the existing shielded wire grounding system, the connection stability and sealing effect of the shielding wire are poor, and it cannot provide good protection for the connection between the shielding wire and the terminal.

At this time, the driving connection block 4 can disconnect the electrical equipment body 1 and the shielding wire assembly 3, thereby effectively improving the portability of the device.

[0045] Embodiment 4: Embodiment 4 is substantially the same as Embodiment 1, except that: The fixing assembly 5 includes a forward and reverse screw 52 and a first rotating handle 53. A first cavity 51 is provided in the connecting block 4. The forward and reverse screw 52 is rotatably connected inside the first cavity 51. The top end of the forward and reverse screw 52 extends to the outside of the connecting block 4 and is connected to the first rotating handle 53; a first threaded sleeve 54 is threadedly connected to the forward and reverse screw 52, ​​and the outer side of the first threaded sleeve 54 is connected to two sliding plates 55, and the opposite side of the two sliding plates 55 is connected to a shaped fixing block 56; two second sliding blocks are provided on one side of the sliding plate 55, and the other side of the second sliding block is slidably connected to a second slide rail, and the other side of the second slide rail is fixedly connected to the inner wall of the connecting block 4.

[0046] When in use: drive the first turning handle 53 to make it drive the forward and reverse screws 52 to rotate, and utilize the linkage effect between the forward and reverse screws 52 and the two first threaded sleeves 54 to transmit power to the two first threaded sleeves 54, so that the two first threaded sleeves 54 drive the two sliding plates 55 and the arc-shaped fixed block 56 to move relative to each other, and the arc-shaped fixed block 56 contacts the outer surface of the outer insulating layer 35 to ensure the stability of the connection between the connecting block 4 and the shielding wire assembly 3.

[0047] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed by the present invention should be included in the protection scope recorded in the claims.
