DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 8 , an antenna isolation frame fastening device, the antenna isolation frame is surrounded by a plurality of isolation plates 14, the fastening device includes a plurality of fastening units, the isolation plate 14 is installed between two adjacent fastening units, the fastening unit includes a bottom plate 6 fixedly arranged on a reflecting plate 11, an outer baffle plate 1 and an inner baffle plate 3 are vertically fixed on the bottom plate 6, and an installation slot 2 for accommodating the isolation plate 14 is formed between the outer baffle plate 1 and the inner baffle plate 3.

[0023] When the present invention is used, the bottom plate 6 is first fixed to the reflector 11, and then the isolation plate 14 is inserted into the installation slot 2 to fix the isolation frame. Compared with the prior art, the present invention does not need to add an additional insulating pad, and the isolation plates 14 and the isolation plates 14 and the reflector 11 can be insulated by the fastening unit. Moreover, the isolation plate 14 of the present invention is installed in a plug-in manner, and there is no need to perform complex operations such as R-type rivet installation in the narrow space in the reflector 11, which is faster and more convenient.

[0024] Furthermore, the upper surface of the bottom plate 6 is integrally connected with a reinforcing rib net 7, and a notch is set at the edge of the reinforcing rib net 7 to form an anti-foolproof positioning groove 9, and the isolation plate 14 is integrally connected with an anti-foolproof positioning plate 16, and the end of the anti-foolproof positioning plate 16 is inserted into the anti-foolproof positioning groove 9. The reinforcing rib net 7 is used to increase the strength of the bottom plate 6, and the anti-foolproof positioning plate 16 cooperates with the anti-foolproof positioning groove 9 to effectively eliminate the hidden danger of the isolation plate 14 being installed in the reverse direction. In other embodiments of the present invention, the anti-foolproof positioning groove 9 can also be opened on the bottom plate 6, or an additional pad is added to the bottom plate 6, and the anti-foolproof positioning groove 9 is opened on the pad.

[0025] Furthermore, the isolation plate 14 and the fool-proof positioning plate 16 are perpendicular to each other, the mounting slot 2 is vertically arranged, and the fool-proof positioning slot 9 is horizontally arranged.

[0026] Furthermore, the fixing method of the base plate 6 is as follows: at least one mounting buckle 8 and at least one positioning boss 10 are fixedly connected to the bottom of the base plate 6, and a mounting hole 12 corresponding to the mounting buckle 8 and a positioning hole 13 corresponding to the positioning boss 10 are provided on the reflective plate 11. The positioning boss 10 and the positioning hole 13 cooperate to limit the position of the fastening unit. According to the size of the isolation plate 14, the installation requirements of the isolation plate 14 can be met by controlling the position of the positioning hole 13 without changing the structure of the fastening unit itself, thereby greatly improving the versatility of the present invention. The mounting buckle 8 cooperates with the mounting hole 12 to set the fixing method of the fastening unit to plug-in, which greatly reduces the complexity of the installation process and improves the installation efficiency compared with the existing method of connecting through R-type rivets.

[0027] Furthermore, a fixing buckle 5 facing the outer baffle 1 is fixedly provided on the inner baffle 3, and a fixing hole 15 for cooperating with the fixing buckle 5 is provided on the isolation plate 14. The fixing buckle 5 and the fixing hole 15 cooperate to fix the position of the isolation plate 14, and can effectively prevent the isolation plate 14 from falling off during transportation. Because the fixing buckle 5 is an elastic structure, it will not affect the plugging process of the isolation plate 14.

[0028] Furthermore, in this embodiment, the antenna isolation frame is enclosed by four isolation plates 14, and the fastening device includes four fastening units.

[0029] Furthermore, two adjacent isolation plates 14 are perpendicular to each other, the outer baffle plate 1 and the inner baffle plate 3 are both configured as L-shaped plates, the mounting slot 2 is composed of two parts perpendicular to each other, and the two adjacent isolation plates 14 are respectively inserted into the two parts.

[0030] Four isolation plates 14 are a conventional arrangement in the art. In practical applications, if another number of isolation plates 14 is required, the fastening unit needs to be adaptively adjusted. Specifically, the angle between the two parts of the mounting slot 2 needs to be changed.

[0031] Furthermore, because the fastening unit needs to achieve insulation between the isolation plates 14 and between the isolation plates 14 and the reflector 11 to ensure the stability of the overall PIM performance of the antenna, the fastening unit needs to be made of insulating material. In this embodiment, the fastening unit is injection molded using POM material, that is, the outer baffle 1, the inner baffle 3, the fixing buckle 5, the bottom plate 6, the reinforcing rib net 7, the mounting buckle 8 and the positioning boss 10 are set as an integrated structure, which greatly simplifies the processing technology and reduces the processing cost. In other embodiments of the present invention, other materials with the same characteristics can also be used.

[0032] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
