[0026] Embodiment, please refer to Figures 1-3 The present invention provides a technical solution:

[0027] A VGA cable for a computer, comprising a VGA connector 1 and a connecting cable 2. A fixing post 3 is fixedly installed on the outer surface of the VGA connector 1. A fastening screw 4 penetrates through one side of the fixing post 3 away from the VGA connector 1. A friction sleeve 5 is fixedly sleeved on the outer front end of the fastening screw 4. A first magnetic ring 501 is fixedly arranged on the outer side of the friction sleeve 5. A second magnetic ring 301 is sleeved on the outer front end of the fixing post 3. A protection mechanism 6 is arranged between the connecting cable 2 and the VGA connector 1;

[0028] Specifically, there are two VGA connectors 1, and the shapes and sizes of the two VGA connectors 1 are the same. The fixing posts 3 are symmetrically distributed about the outer surface of the VGA connector 1. The front surface of the second magnetic ring 301 is flush with the front surface of the fixing post 3, and its front surface is magnetically connected to the rear surface of the first magnetic ring 501;

[0029] In this implementation, the magnetic attraction setting of the first magnetic ring 501 and the second magnetic ring 301 enhances the stability between the fastening screw 4 and the fixing post 3, effectively preventing the fastening screw 4 from loosening and meeting the connection requirements of the connector.

[0030] In this embodiment, please refer to Figure 1 and Figure 3 , the protection mechanism 6 includes a protective sleeve 601 and a fixing ring 602. The protective sleeve 601 is sleeved on the outer surface of the connecting cable 2, and a moving ring 603 is fixedly sleeved on its outer side. A card hole 604 is formed on the outer surface of the moving ring 603. The fixing ring 602 is fixedly installed on the front end surface of the VGA connector 1, and an installation hole 605 is formed on its outer surface. A support compression spring 606 and a clamping post 607 are respectively arranged inside the installation hole 605;

[0031] Specifically, the inner wall of the fixing ring 602 is in contact with the outer surface of the connecting cable 2. The inner wall of the protective sleeve 601 is in sliding fit with the outer surface of the connecting cable 2, and it is made of rubber material. The inner wall of the moving ring 603 is in contact with the outer surface of the fixing ring 602. The installation holes 605 are arranged in a left-right mirror image about the outer surface of the fixing ring 602. One end of the support compression spring 606 is fixed to the inner wall of the installation hole 605, and the other end of it is fixed to one end of the clamping post 607. The outer surface of the clamping post 607 is in fit with the inner wall of the installation hole 605. The card hole 604 is arranged corresponding to the clamping post 607 and is in snap connection;

[0032] In this embodiment, the movable ring 603 is mainly arranged to contact the outer surface of the fixed ring 602. The support compression spring 606 is arranged to support the clamping post 607, so that the clamping post 607 is in close contact with the clamping hole 604, thereby achieving the function of fixing the protective sleeve 601. The close contact between the protective sleeve 601 and the connecting wire 2 is mainly used to wrap the connecting wire 2, thereby achieving the function of protecting the connecting wire 2 and extending the service life of the connecting wire 2.

[0033] The working process of the utility model: When using a VGA connecting wire for a computer, first move the movable ring 603 to make it contact the fixed ring 602. Under the elastic support of the support compression spring 606, the clamping post 607 and the clamping hole 604 form a clamping fit, ensuring the stability of the movable ring 603 and the protective sleeve 601. Under the action of the protective sleeve 601, the connecting wire 2 is protected and the service life of the connecting wire 2 is extended. Finally, connect the VGA connector 1 to the device. During the connection process, rotate the fastening screw 4 through the friction sleeve 5 to make the fastening screw 4 in screw-threaded contact with the screw hole of the device. Then, the fastening screw 4 drives the first magnetic ring 501 and the second magnetic ring 301 to gradually approach. Under the magnetic attraction cooperation of the first magnetic ring 501 and the second magnetic ring 301, the stable state of the fastening screw 4 is ensured, effectively reducing the loosening of the fastening screw 4 due to vibration and improving the connection stability between the VGA connector 1 and the device, which is convenient for subsequent use.
