[0037] Protective shell 201 is used as the external protection structure of VGA connector 2, plays the role of protecting internal components from physical damage such as collision and extrusion, and provides a support frame for the installation of other components, and the connecting holes 206 provided on both sides thereof are used to connect the locking piece 202.

[0038] Locking piece 202 is provided with two, respectively located on both sides of protective shell 201, containing connecting screw 202a and knob 202b. The connecting screw 202a is fixedly connected with the knob 202b, the knob 202b is provided with a cutout 202c, a group of auxiliary dismounting pieces 202d are symmetrically arranged in the cutout 202c, the auxiliary dismounting pieces 202d are connected with the knob 202b body through a pin shaft, and the boss 202e at the top end of the auxiliary dismounting piece 202d is convenient for pulling out the auxiliary dismounting piece 202d from the cutout 202c. In actual use, the connecting screw 202a is tightly matched with the internal thread 207 at both ends of the connecting hole 206, and the stable connection makes the whole locking piece 202 not easy to shake during use, when the female end connecting port of the equipment is docked, the VGA connector 2 can be quickly and accurately positioned and connected, greatly improving the connection efficiency; and when dismounting is difficult, the auxiliary dismounting piece 202d is pulled out, and the knob 202b presents a shape similar to a butterfly screw, compared with the traditional columnar knob, the user's hand can more conveniently exert force, and the dismounting operation is more easy, greatly facilitating the dismounting process of the connector and the equipment interface.

[0039] The bottom plate 203 and the plug shell 204 are integrally formed, one end surface of the bottom plate 203 is fixedly connected with the protective shell 201, the stability of the whole VGA connector 2 structure is enhanced, the cooperation of the components is ensured, and a stable supporting foundation is provided for the pin 205.

[0040] The plug shell 204 is provided with a compression spring 208 and an avoidance groove 209 on the upper and lower edges. One end of the compression spring 208 is fixedly connected with the plug shell 204, is obliquely arranged and extends to the inside of the plug shell 204 at the unconnected end. When the plug is inserted into the equipment interface, the compression spring 208 will be elastically deformed due to the extrusion of the interface wall, tightly fit the outer wall of the female end structure, play a good fixing role, effectively prevent the connection from loosening due to the movement, vibration and other factors of the equipment during use; the avoidance groove 209 is arranged at a position corresponding to the compression spring 208, and provides a storage space for the deformation of the compression spring 208.

[0041] The pin 205 is provided with a plurality of pins, one end of which extends to the outside of the protective shell 201, used for connecting with the corresponding jack in the equipment interface, realizing signal transmission; the other end extends to the inside of the protective shell 201 and is electrically connected with the wire in the data line 1, ensuring that the data can be stably transmitted between the equipment and the data line 1.

[0042] The both ends of the connecting hole 206 are provided with internal threads 207, and the internal threads 207 are matched with the connecting screw rod 202a, so that the locking piece 202 can be firmly installed on the protective shell 201, and the tightness can be accurately adjusted by rotating the knob 202b, facilitating the connection and disassembly with the equipment interface.

[0043] The knob 202b and the auxiliary dismounting sheet 202d are made of plastic material, which not only ensures a certain strength to withstand the torsion force during rotation operation, but also has good insulation to prevent the risk of electric leakage; the outer wall of the knob 202b is provided with anti-skid lines to increase the friction between the hand and the knob 202b, facilitate the user to rotate the knob 202b, and the operation is more convenient.

[0044] The data line 1 is also provided with two magnetic rings 3, the two magnetic rings 3 are arranged between the two VGA connectors 2, and the magnetic ring 3 is covered on the data line 1 by plastic.

[0045] Working principle:

[0046] When the connection operation is performed, the user holds the VGA connector 2, aligns the plug shell 204 with the VGA interface of the device, and inserts it gently with smooth and slow action. In this process, the compression spring 208 on the plug shell 204 is elastically deformed due to the extrusion of the outer wall of the female interface, and the avoidance groove 209 provides a storage space for the deformation of the compression spring 208. Until the plug is fully inserted, at which time the compression spring 208 closely fits the outer wall of the female interface.

[0047] At the same time, the connecting screw 202a is tightly matched with the internal thread 207 at both ends of the connecting hole 206, quickly aligning one end of the connecting screw 202a with the thread on the female interface, and then turning the knob 202b to connect the VGA connector with the female end. Since the outer wall of the knob 202b is provided with anti-skid lines, the friction between the hand and the knob 202b is increased, facilitating the user to operate, accurately adjusting the tightness by rotating the knob 202b, further ensuring that the connector is tightly connected with the device interface, and preventing loosening.

[0048] The two magnetic rings 3 on the data line 1 utilize their own electromagnetic shielding characteristics. When external electromagnetic interference exists, the magnetic ring 3 can guide the magnetic lines of force of the interference electromagnetic field to concentrate inside the magnetic ring 3, avoiding the interference magnetic lines from passing through the data line 1, thereby effectively reducing the influence of external electromagnetic interference on the signal transmission of the data line 1, ensuring the stability and clarity of signal transmission, especially in a complex electromagnetic environment, ensuring that the image signal is not disturbed and is stably transmitted.

[0049] When disassembly is needed, if the connection is tight, the user can stably hold the knob 202b, increase the friction by the anti-skid lines on the outer wall, and slowly rotate the knob 202b to make the connecting screw 202a loose outward. If it still feels laborious, the auxiliary disassembly piece 202d in the cutout 202c can be carefully pulled out by the boss 202e, at which time the knob 202b assumes a shape similar to a butterfly screw, the user can more easily exert force to rotate, and with the help of the additional force point provided by the auxiliary disassembly piece 202d, the separation of the connector and the device interface is more quickly achieved. The whole process is simple to operate and is not easy to cause damage to the device interface.
