[0028] In order to make the above - mentioned objects, features, and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0029] To solve the problem of poor firmness and stability of the grounding plate, the present utility model provides a new type of grounding plate, which is installed inside the multi - frequency antenna system 7. Refer to Figure 1 - Figure 2 As shown, the new type of grounding plate includes a grounding plate body 1 for connecting with the antenna board 6, and a central hole 11 is opened in its center; a connecting plate 2 is vertically arranged on both symmetrical sides of the grounding plate body 1; fixing grooves 3 are arranged on both symmetrical sides far away from the grounding plate body 1 through the connecting plate 2 for fixing the cable 5; a positioning member 4, and the positioning member 4 is connected to the bottom of the grounding plate body 1; the grounding plate body 1 is connected to the antenna board 6 through the positioning member 4.

[0030] For the new type of grounding plate provided by the present utility model, the positioning member 4 at the bottom of the grounding plate body 1 is embedded into the hole groove of the antenna board 6, which can preliminarily position and fix the whole grounding plate. Secondly, the screw 8 passes through the central hole 11 in the center of the grounding plate body 1, which can further strengthen the connection between the grounding plate and the antenna board 6. The combination of the central hole 11 and the positioning member 4 not only plays a role in accurate positioning, but also significantly improves the stability of the installation of the grounding plate, ensuring that the multi - frequency antenna system 7 is not interfered, thereby improving its signal transmission quality and stability. In addition, the fixing grooves 3 arranged on both symmetrical sides far away from the grounding plate body 1 through the connecting plate 2 can be tightly connected with the cable 5, greatly increasing the contact area, enhancing the reliability between the grounding plate and the cable line, and further improving the stability of the grounding plate. At the same time, it ensures the effective distribution of the cable line, effectively avoids the winding problem caused by the complexity of the cable line, ensures the stable performance of the multi - frequency antenna system 7, and improves the aesthetics of the grounding plate. In addition, the present utility model is small in size, low in cost, easy to install, and strong in stability, and is suitable for large - scale production.

[0031] Specifically, refer toFigure 1 As shown, to further improve the stability of the structure, in the present utility model, the positioning member 4 preferably includes a positioning pin 41 and an insulating member 42; a slot 421 is formed in the insulating member 42; the positioning pin 41 is inserted into the slot 421, and the positioning pin 41 is fixedly connected to the bottom of the grounding plate body 1; the insulating member 42 is embedded in the antenna board 6.

[0032] In the present utility model, preferably, a groove 12 is provided on the grounding plate body 1, and the groove 12 is in a disc shape; the central hole 11 is provided at the central position of the groove 12; this not only effectively reduces the material usage amount, thereby reducing the cost, but also ensures that the screw 8 after installation does not protrude from the upper surface of the grounding plate body 1, making the surface of the entire structure smoother. While improving the appearance quality of the product, it also helps to reduce possible scratches or damages during the installation process, maintaining the compactness and integrity of the structure.

[0033] In the present utility model, preferably, the fixing groove 3 is in a U shape; and preferably, the diameter of the fixing groove 3 is not less than the diameter of the cable 5. The U-shaped structure of the fixing groove 3 ensures a stable connection between the cable and the grounding plate, reducing unstable factors caused by cable movement or vibration; at the same time, the diameter of the fixing groove 3 is not less than the diameter of the cable 5, effectively avoiding the risk that the cable 5 will be overly squeezed, protecting the integrity of the cable, simplifying the installation process, making the cable easy to insert and fix, and also facilitating maintenance and replacement; in addition, the larger contact area helps to improve the heat dissipation efficiency and extend the service life of the cable.

[0034] In the present utility model, preferably, the positioning pin 41 is in a conical shape; and a plastic layer is attached to the outside of the positioning pin 41. The tip design of the cone facilitates insertion into the slot 421 in the insulating member 42 to achieve precise positioning; in addition, the outside of the positioning pin 41 is covered with a plastic layer, which can provide additional protection to prevent electrical connection, thereby ensuring good insulation performance, and also helping to reduce friction and wear that may occur during the installation process.

[0035] In the present utility model, preferably, the number of the positioning pins 41 is one. While simplifying the structure and reducing the cost, it can ensure the required positioning accuracy and stability.

[0036] To provide stable support and enhance the insulation effect, in the present utility model, preferably, the insulating member 42 is in a T shape; and preferably, the upper surface of the insulating member 42 is an insulating layer 422.

[0037] In the present utility model, it is preferred that the grounding plate body 1, the connecting plate 2, the fixing groove 3 and the positioning member 4 are all made of metal conductive materials. Further, it is preferred that the grounding plate body 1, the connecting plate 2, the fixing groove 3 and the positioning member 4 are all made of copper; due to the high conductivity and good mechanical properties of copper, the efficiency and stability of the grounding plate in electrical connection and signal transmission are ensured; at the same time, the corrosion resistance of copper also helps to improve the durability and long-term reliability of the product.

[0038] In the present utility model, it is preferred that the grounding plate body 1, the connecting plate 2, the fixing groove 3 and the positioning member 4 are integrally formed. This not only improves the overall structural strength and stability of the product, but also effectively reduces costs and improves production efficiency by simplifying the production process and reducing the assembly links.

The simple installation steps and high-efficiency performance make the novel grounding plate of the present utility model an ideal choice for improving the performance of the multi-band antenna system 7.

[0040] When the novel grounding plate is in use, first, insert the positioning pin 41 at the bottom of the grounding plate body 1 into the slot 421 in the insulating member 42, and then embed the insulating member 42 into the hole groove of the antenna board 6 to ensure the preliminary positioning and fixing of the grounding plate on the antenna board 6; then, pass the screw 8 through the central hole 11 at the center of the grounding plate body 1 to further strengthen the connection between the grounding plate and the antenna board 6; finally, arrange the two cables 5 on the antenna board 6 and weld them to the fixing grooves 3 provided on the symmetric two sides far from the grounding plate body 1 through the connecting plate 2 respectively, which not only ensures sufficient contact between the cable 5 and the grounding plate, but also assists in fixing the grounding plate to a certain extent.
