[0029] Please refer to Figures 1-4 , a kind of welding-free VGA connector shown, including upper shell 1, lower shell 2, PCB board 3, pin 4, pin shell 5, wiring terminal row 6 and locking piece 7.

[0030] The upper shell 1 is the protective upper layer of the whole connector, mainly plays the role of protecting internal components and providing structural support. It is connected with the lower shell 2 by bolt, forms a closed and stable cavity, effectively prevents the invasion of impurities such as dust, water vapor from outside, and guarantees the normal operation of internal electrical elements. Its material has certain strength and toughness, can withstand slight collision and extrusion in daily use, ensures the integrity of the connector.

[0031] The lower shell 2 carries the PCB board 3, and the inner cavity bottom surface of the lower shell 2 is fixed with the PCB board 3 by means of adhesion. The adhesion process ensures the stable position of the PCB board 3 inside the joint, avoiding the influence of signal transmission due to shaking or displacement. At the same time, one side edge of the lower shell 2 is fixedly connected with the pin shell 5, which provides accurate guidance and support for the pin 4, so that the pin 4 can be accurately inserted into the corresponding female interface, ensuring the reliability of signal connection. In addition, the lower shell 2 is also provided with four reinforcing blocks 8, which are evenly distributed in the four corners of the inner cavity. Each reinforcing block 8 is provided with a threaded hole 9. These reinforcing blocks 8 greatly enhance the structural strength of the lower shell 2, so that it can better protect the internal components when facing external force impact, prolonging the service life of the joint.

[0032] The PCB board 3 is the core signal processing and transfer component, which is the "brain" of the entire VGA joint. It integrates various circuit elements, responsible for processing, converting and distributing the input and output signals, ensuring that the video signal can be accurately and stably transmitted. On the one hand, it is connected with one end of the pin 4 through the welding point, so that the externally accessed video signal can be smoothly introduced into the PCB board 3 for processing; on the other hand, it provides a fixed point for the terminal row 6 and is electrically connected with the pins, so that the data line accessed from the outside can be tightly connected with it, realizing the interactive transmission of data.

[0033] The pin 4 is made of copper material, which has excellent electrical conductivity and can minimize signal transmission loss, ensuring high-quality transmission of video signals. One end of the pin 4 penetrates through the lower shell 2 near the side edge of the pin shell 5, accurately extending into the inner cavity of the pin shell 5 to tightly contact the corresponding pin of the female interface, realizing physical connection of signals; the other end is connected with the corresponding soldering point on the PCB board 3, smoothly introducing the externally accessed signal into the PCB board 3 for subsequent processing.

[0034] The pin shell 5 is fixedly connected with the lower shell 2, and it tightly wraps the one end of the pin 4, playing a role in protecting the pin 4 and assisting the pin 4 in accurately docking with the female interface. During the plugging process, the pin shell 5 can prevent the pin 4 from being bent or damaged by external force, ensuring stable and reliable connection each time, and also providing more intuitive plugging operation guidance for the operator, improving the convenience of use.

[0035] The terminal row 6 is fixedly arranged on the PCB 3. When connecting the data line, the data line is only needed to be inserted into the wire pressing port, and the spring or reed structure in the interior is pressed tightly under the lever action of the wrench to realize the close and reliable electrical connection. The traditional welding mode is abandoned, the welding technology requirement for the worker is greatly reduced, and the signal transmission failure caused by the welding quality problem is reduced. Meanwhile, when the data line is maintained or replaced, the operation is extremely simple, and the welding is not needed, so that the maintenance cost is greatly reduced, and the production and maintenance efficiency is improved.

[0036] The locking member 7 comprises a rotating cap body 7 and a locking bolt 702, and is provided with two, which are symmetrically arranged on the two sides of the lower shell 2. When connected with the female end, the locking bolt 702 is rotated by rotating the cap body 7, so that the locking bolt 702 can tightly abut against the corresponding part of the female end, and the locking and fixing of the joint and the female end are realized. This design ensures that the connection between the VGA joint and the female end will not be loosened due to accidental pulling, shaking and the like during use, and guarantees the stability of signal transmission, and improves the safety and reliability in use.

[0037] The upper shell 1 is provided with four connecting bolts 10, and the positions of the connecting bolts 10 correspond to the positions of the four threaded holes 9. The upper shell 1 and the lower shell 2 are tightly connected through the cooperation of the connecting bolts 10 and the threaded holes 9.

[0038] The inner cavities of the upper shell 1 and the lower shell 2 are both provided with a shielding sheet 11. One of the two shielding sheets 11 is arranged on the inner cavity wall of the upper shell 1 by gluing, and the other shielding sheet 11 is arranged on the inner cavity wall of the lower shell 2 by gluing, and is arranged between the lower shell 2 and the PCB 3, and the shielding sheet 11 at this position is directly insulated with the PCB 3. Such a design can effectively block the external electromagnetic interference, prevent the external messy electromagnetic signals from affecting the video signal transmission in the VGA joint, guarantee the stability and reliability of signal transmission, and improve the performance of the product; and can also avoid the electrical short circuit between the shielding sheet and the PCB 3, and ensure the normal work of the joint.

[0039] The upper shell 1 and the lower shell 2 are both provided with a semicircular hole 12 for the extension of the wire. This design enables the external data line to pass through naturally and smoothly when connected to the joint, avoids the bending and winding of the wire, protects the wire, and ensures the stability of data transmission.
