[0023] The specific embodiments of the present application will be further described below with reference to the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the present application, and cannot be used to limit the protection scope of the present application.

[0024] The "top surface", "bottom", "bottom surface" are referenced to the normal use state of the panel antenna, and are only for the convenience of describing the present application and simplifying the description, and are not indicative or suggestive of the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0025] As shown in Figure 1 and 2 , a panel antenna for liquid crystal display screen includes an antenna body 1 and a cable 2 fixedly connected to each other, the cable 2 is sleeved with an elastic positioning sleeve 4, the antenna body 1 is detachably connected with a U-shaped clamp 3, the positioning sleeve 4 is fixedly connected with the antenna body 1 through the clamp 3, and the positioning sleeve 4 is located on the inner side of the U-shaped opening of the clamp 3.

[0026] The above-mentioned panel antenna is used for communication of the liquid crystal display screen. In the panel antenna, one end of the cable 2 is welded on the antenna body 1, and the other end is provided with a connector for connecting the main board of the liquid crystal display screen; both ends of the clamp 3 are fixedly connected with the antenna body 1, and the cable 2 is located on the inner side of the clamp 3, so as to fix the cable 2 on the antenna body 1 through the clamp 3. In this way, in the process of antenna debugging and assembly, the bending of the cable 2 will only cause the bending of the part fixed by the cable 2 and the clamp 3, and the welding part of the cable 2 and the antenna body 1 will not be bent, thereby reducing the probability of loosening or breaking of the welding point of the cable 2 and the antenna body 1, and reducing the failure rate of the panel antenna.

[0027] The positioning sleeve 4 is a silica gel sleeve, which is arranged between the clamp 3 and the cable 2 to increase the friction therebetween and improve the firmness of the fixation of the cable 2. Meanwhile, the positioning sleeve 4 can separate the cable 2, the antenna body 1 and the clamp 3 to reduce the abrasion of the three, thereby reducing the failure rate of the panel antenna. After the cable 2 and the antenna body 1 are fixed to each other by welding, the relative position therebetween can be limited to realize the mutual positioning during welding, thereby improving the welding quality and further reducing the failure rate of the panel antenna.

[0028] Further improvement is that, as shown in Figure 4 , the clamp 3 is integrally provided with a protective cover 302, and the welding point of the cable 2 and the antenna body 1 is located on the inner side of the protective cover 302.

[0029] Specifically, the clamp 3 and the protective cover 302 are integrally formed plastic parts. After the clamp 3 is fixed with the antenna body 1, the cable 2 and the welding point of the antenna body 1 can be covered inside the protective cover 302. During subsequent debugging, testing and assembly, the probability of collision between the cable 2 and the welding point of the antenna body 1 can be reduced, thereby reducing the probability of loosening or falling off at the welding point and reducing the failure rate of the flat plate antenna.

[0030] Further improvement is that, as shown in Figure 3 and 4 , the antenna body 1 is provided with a plug-in hole 101, and both ends of the clamp 3 are provided with a plug-in part 301 which is plugged into the plug-in hole 101. The plug-in part 301 and the clamp 3 are integrally formed, the antenna body 1 is provided with two plug-in holes 101, and the two plug-in parts 301 are respectively plugged into the two plug-in holes 101. The plug-in part 301 and the plug-in hole 101 are in interference fit, and under the action of friction between them, the clamp 3 and the antenna body 1 are fixedly connected with each other, improving the convenience of installing the clamp 3 on the antenna body 1.

[0031] Further improvement is that, as shown in Figure 4 and 6 , the side of the antenna body 1 away from the clamp 3 is provided with a limiting plate 5, and the plug-in part 301 penetrates through the plug-in hole 101, and the two plug-in parts 301 are respectively connected with the limiting plate 5. The area of the limiting plate 5 is larger than the opening area of the plug-in hole 101. After the limiting plate 5 is connected with the plug-in part 301, the limiting plate 5 is abutted against the side of the antenna body 1 away from the clamp 3, thereby preventing the plug-in part 301 from falling off from the plug-in hole 101 under the action of the limiting plate 5, improving the firmness of the connection between the clamp 3 and the antenna body 1, and further improving the firmness of the fixation of the cable 2.

[0032] Further improvement is that, as shown in Figure 6 , the limiting plate 5 is provided with a limiting through slot 501, the plug-in part 301 is plugged into the limiting through slot 501, and the limiting through slot 501 is a T-shaped slot or a dovetail slot. In use, after the plug-in part 301 penetrates through the plug-in hole 101, the limiting plate 5 is moved along the direction parallel to the antenna body 1, so that one end of the plug-in part 301 penetrating through the plug-in hole 101 is inserted into one end of the limiting through slot 501, thereby realizing the mutual fixation between the plug-in part 301 and the limiting plate 5. The limiting through slot 501 is a T-shaped slot or a dovetail slot, which can prevent the plug-in part 301 from separating from the limiting through slot 501 along the extension direction of the plug-in hole 101, thereby improving the firmness of the connection between the plug-in part 301 and the limiting plate 5. At the same time, the elasticity of the positioning sleeve 4 can also exert a force on the clamp 3, so as to increase the friction between the clamp 3 and the limiting plate 5, thereby further improving the firmness of the connection between the two, and finally improving the stability of the fixation of the cable 2.

[0033] Further improvement is that, as shown inFigure 5 As shown in the figure, the positioning sleeve 4 is coaxially provided with an elastic extension tube 401, and the extension tube 401 is sleeved on the outer periphery of the cable 2. The end of the cable 2 connected with the mainboard of the liquid crystal display is a movable end, and the extension tube 401 is located on the side of the positioning sleeve 4 close to the movable end. The extension tube 401 is also made of silica gel. In the process of bending the cable 2, the elasticity of the extension tube 401 can prevent the part of the cable 2 connected with the clamp 3 from being excessively bent, thereby reducing the probability of the part of the cable 2 connected with the clamp 3 being broken, and reducing the failure rate of the flat antenna.

[0034] Further improvement is that, as shown in the figure, Figure 3 As shown in the figure, the side of the antenna body 1 away from the clamp 3 is provided with adhesive tapes 6; the adhesive tapes 6 are provided in plurality, and the adhesive tapes 6 are arranged at intervals, and the thickness of the adhesive tapes 6 is greater than or equal to the thickness of the limiting plate 5. The antenna body 1 is adhered to the inside of the liquid crystal display through the adhesive tapes 6, so that the convenience of installing the flat antenna can be improved. The adhesive tapes 6 can keep a certain interval between the antenna body 1 and the mounting surface, and an interval is kept between the adjacent two adhesive tapes 6. In this way, after the flat antenna is installed, an interval for air circulation is left between the flat antenna and the mounting surface, so that the heat dissipation area of the flat antenna is increased, and the heat dissipation effect is improved. Compared with the adhesive tapes 6 pasted on the back of the entire antenna body 1, the distribution mode of the above adhesive tapes 6 can also reduce the amount of the adhesive tapes 6, and reduce the production cost.

[0035] It can be understood that the utility model is described through some embodiments, and those skilled in the art know that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model.
