[0001] The present invention relates to the technical field of mobile antenna base station equipment, and particularly relates to a fixed installation and grounding device for an antenna controller. Background Art

[0002] In the communication industry, it is usually necessary to adjust the electrical downtilt angle of an antenna through an antenna controller. Currently, the mainstream installation method of the controller is to directly fix it on the metal rails on both sides, and the controller is grounded to the antenna bottom plate through the metal rails.

[0003] However, in this installation method, since the metal rails on both sides of the controller need to be fixed to the antenna bottom plate and the pluggable controller respectively, the metal contact area is large, which easily causes the problem of third-order intermodulation to the antenna. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems proposed in the background art. To achieve the purpose of the present invention, the following technical solutions are adopted:

Among them, the right guiding installation mechanism includes a right guiding member made of a non-metallic material, a right fixing member made of a metal material, a guiding fastener, and an end cover fastener. The right guiding member includes a guiding member body and a first isolation surface and a second isolation surface attached to the guiding member body;

[0006] The right fixing member is fixedly connected to the right guiding member. The end cover fastener sequentially passes through the front end cover of the antenna controller, the first isolation surface, and the right fixing member to fixedly connect and conduct the front end cover of the antenna controller with the right fixing member. The guiding fastener sequentially passes through the right fixing member, the second isolation surface, and the antenna bottom plate to fixedly connect and conduct the right fixing member with the antenna bottom plate, thereby realizing the grounding of the antenna controller.

[0007] A further improvement is that a fixing groove is formed between the first isolation surface and the front wall of the guiding member body for the right fixing member to be inserted into, and the bottom wall of the guiding member body vertically extends outward to form the second isolation surface.

[0008] A further improvement is that the right fixing member includes a fixing plate body, a first side plate, and a second side plate.

The bottom wall of the fixing plate body vertically extends outward to form the second side plate. The first isolation surface is located between the front end cover of the antenna controller and the first side plate, and the second isolation surface is located between the antenna bottom plate and the second side plate.

[0009] Further improvements are as follows. There is an end - cover hole provided on the front end - cover, a semi - circular hole provided on the first isolation surface, and a screw hole provided on the first side plate. The end - cover fastener sequentially passes through the end - cover hole, the semi - circular hole, and the screw hole to realize the fixed connection and electrical conduction between the front end - cover of the antenna controller and the right fixing member.

[0010] Further improvements are as follows. There is a lower through - hole provided on the second side plate, an installation through - slot provided on the second isolation surface, and a fastening hole provided on the antenna bottom plate.

[0012] Further improvements are as follows. The right guiding member is integrally injection - molded from a plastic material, and the right fixing member is formed by bending a sheet metal.

[0013] Further improvements are as follows. There are card feet provided on the guiding member body, and card - foot holes adapted to the card feet are provided on the antenna bottom plate. The card feet are inserted into the card - foot holes.

[0014] Further improvements are as follows. A sliding groove is provided along the length direction of the guiding member body on the side wall of the guiding member body, and a sliding rail matched with the sliding groove is provided on the antenna controller. The sliding rail and the sliding groove are slidably matched to realize the installation and positioning of the antenna controller.

[0015] Further improvements are as follows. The left guiding installation mechanism and the right guiding installation mechanism are respectively located on both sides of the antenna controller and are mirror - symmetric about the center line of the antenna controller.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. Further, when an element is considered to be "drivably connected" to another element, the two can achieve power transmission, and its specific implementation manner can be realized by using the existing technology and will not be elaborated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is perpendicular, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific implementation manners and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] In the present invention, "first" and "second" do not represent specific quantities or orders, but are merely used for name differentiation.

[0027] Please refer to Figures 1 - 3 , an embodiment of the present invention provides a fixed installation and grounding device for an antenna controller 1, including an antenna bottom plate 4 and a left guiding installation mechanism and a right guiding installation mechanism for fixedly installing the antenna controller 1. Among them, the right guiding installation mechanism includes a right guiding member 2 made of a non-metallic material and non-conductive, a right fixing member 3 made of a metallic material and conductive, a guiding fastener 5, and an end cover fastener 8. The right guiding member 2 includes a guiding member body and a first isolation surface 26 and a second isolation surface 27 attached to the guiding member body.

[0028] The right fixing member 3 is fixedly connected to the right guiding member 2. The end cover fastener 8 sequentially passes through the front end cover 11 of the antenna controller 1, the first isolation surface 26, and the right fixing member 3 to fixedly connect and conduct the front end cover 11 of the antenna controller 1 and the right fixing member 3. The guiding fastener 5 sequentially passes through the right fixing member 3, the second isolation surface 27, and the antenna bottom plate 4 to fixedly connect and conduct the right fixing member 3 and the antenna bottom plate 4, thereby realizing the grounding of the antenna controller 1.

[0029] In addition, as Figure 1 and Figure 3 shown, the left guiding installation mechanism also includes a left guiding member 6 made of a non-metallic material and a left fixing member 7 made of a metallic material. Its installation method is the same as that of the right guiding installation mechanism. Specifically, in this embodiment, the left guiding installation mechanism and the right guiding installation mechanism are respectively located on the left and right sides of the antenna controller 1 and are mirror-symmetrical about the center line of the antenna controller 1.

[0030] Since the left guiding member 6 and the left fixing member 7 are respectively in a completely symmetrical mirror relationship with the corresponding right guiding member 2 and right fixing member 3, and their installation and fixation on the antenna bottom plate 4 are exactly the same as the way the right guiding member 2 and the right fixing member 3 are fixed to the antenna bottom plate 4, no repeated description will be made.

[0031] It can be understood that since the front end cover 11, the right fixing member 3, the left fixing member 7, the guiding fastener 5, and the end cover fastener 8 of the antenna controller 1 are all made of metallic materials, the front end cover 11 of the antenna controller 1 and the right fixing member 3 (or the left fixing member 7) can be conducted through the end cover fastener 8, and the guiding fastener 5 conducts the right fixing member 3 (or the left fixing member 7) and the antenna bottom plate 4, thereby realizing the installation and fixation and grounding of the antenna controller 1 at the same time. That is, the guiding fastener 5 and the end cover fastener 8 can simultaneously achieve the functions of fastening and conducting electricity.

[0032] Specifically, in this embodiment, as Figure 2As shown, a fixing groove 22 is formed between the first isolation surface 26 and the front wall of the guide member body for inserting the right fixing member 3, and a second isolation surface 27 extends vertically outward from the bottom wall of the guide member body.

[0033] The right fixing member 3 includes a fixing plate body, a first side plate 32, and a second side plate 35. A first side plate 32 extends vertically outward from the front wall of the fixing plate body for inserting into the fixing groove 22. A second side plate 35 extends vertically outward from the bottom wall of the fixing plate body. The first isolation surface 26 is located between the front end cover 11 of the antenna controller 1 and the first side plate 32, and the second isolation surface 27 is located between the antenna bottom plate 4 and the second side plate 35.

[0034] It can be understood that by setting the first isolation surface 26 between the front end cover 11 of the antenna controller 1 and the first side plate 32, and the second isolation surface 27 between the antenna bottom plate 4 and the second side plate 35, the problem of third-order intermodulation that may occur due to the direct large-area metal contact between the right fixing member 3 and the front end cover 11 of the antenna controller 1 and the antenna bottom plate 4 is effectively avoided.

[0035] Specifically, in this embodiment, an end cover hole 12 is provided on the front end cover 11, a semi-circular hole 25 is provided on the first isolation surface 26, and a screw hole 33 is provided on the first side plate 32. The end cover fastener 8 passes through the end cover hole 12, the semi-circular hole 25, and the screw hole 33 in sequence to realize the fixed connection and conduction between the front end cover 11 of the antenna controller 1 and the right fixing member 3.

[0036] Specifically, in this embodiment, the number of the semi-circular holes 25 and the screw holes 33 in the right guiding and mounting mechanism are both two groups.

[0037] Specifically, in this embodiment, a lower through hole 34 is provided on the second side plate 35, a mounting through groove 28 is provided on the second isolation surface 27, and a fastening hole 42 is provided on the antenna bottom plate 4. The guiding fastener 5 passes through the lower through hole 34, the mounting through groove 28, and the fastening hole 42 in sequence to realize the fixed connection and conduction between the right fixing member 3 and the antenna bottom plate 4.

[0038] Specifically, in this embodiment, a mounting hole 21 is provided on the guide member body, an upper through hole 31 is provided on the fixing plate body, and the right fixing member 3 and the right guiding member 2 are fixedly connected through the guiding fastener 5 cooperating with the mounting hole 21 and the upper through hole 31. The guiding fastener 5 is specifically a metal bolt.

[0039] Specifically, in this embodiment, the right guiding member 2 is integrally injection-molded with a plastic material, and the right fixing member 3 is formed by bending a sheet metal. The right fixing member 3 can specifically be made of metal materials such as aluminum, copper, stainless steel, and aluminum alloy.

[0040] Since the right fixing member 3 and the left fixing member 7 are processed by sheet metal bending, only one pair of injection molds for the right guiding member 2 and the left guiding member 6 needs to be opened, so as to realize the fixed installation and grounding of the antenna controller 1, and the problem of expensive mold opening cost is solved.

[0041] Specifically, in this embodiment, a clamping foot 23 is provided on the guiding member body, and a clamping foot hole 41 adapted to the clamping foot 23 is provided on the antenna bottom plate 4, and the clamping foot 23 is inserted into the clamping foot hole 41.

[0042] It can be understood that during installation, first, the guiding fastener 5 sequentially passes through the upper through hole 31 and the mounting hole 21. After assembling the right fixing member 3 and the right guiding member 2 into one body, this assembly can be pre-mounted in the clamping foot hole 41 of the antenna bottom plate 4 through the clamping foot 23 of the right guiding member 2. Then, the guiding fastener 5 sequentially passes through the lower through hole 34 of the right fixing member 3, the mounting through slot 28 of the right guiding member 2 and the fastening hole 42 of the antenna bottom plate 4 to completely fix the right fixing member 3 and the right guiding member 2 on the antenna bottom plate 4, and then the antenna controller 1 is installed and fixed.

[0043] Specifically, in this embodiment, a sliding groove 24 is provided on the side wall of the guiding member body along the length direction of the guiding member body, a sliding rail 13 matched with the sliding groove 24 is provided on the antenna controller 1, and the sliding rail 13 is slidably matched with the sliding groove 24 to realize the installation and positioning of the antenna controller 1.

[0044] As Figure 1 、 2 and shown in 3, the antenna controller 1 can slide into the right guiding member 2 along the sliding groove 24 of the right guiding member 2 (similarly, it also slides into the left guiding member 6 at the same time). After sliding in, the end cover fastener 8 sequentially passes through the end cover hole 12 of the antenna controller 1, the semi-circular hole 25 of the right guiding member 2 and the screw hole 33 of the right fixing member 3, and the antenna controller 1 can be fixed on the right fixing member 3 (similarly, it is also fixed on the left fixing member 7).

[0045] In one of the embodiments, as Figure 2 shown, the cross section of the first side plate 32 is in a "concave" shape, which is used to cooperate with the structure formed by the sliding groove 24 in the fixing groove 22 of the right guiding member 2, so that the installation structure of the right fixing member 3 is more compact and stable.

[0046] The installation method of the present invention, which combines the right guide member 2 made of non-metallic material with the right fixing member 3, the guide fastener 5, and the end cover fastener 8 made of metallic material, realizes the dual functions of fastening installation and grounding of the antenna controller 1. At the same time, through the first isolation surface 26 and the second isolation surface 27 attached to the guide member body, it effectively avoids the third-order intermodulation problem that may occur due to the direct large-area metal contact between the right fixing member 3 and the front cover 11 of the antenna controller 1 and the antenna bottom plate 4.

[0047] Generally speaking, the fixed installation and grounding device of an antenna controller 1 provided in this embodiment has low production cost, convenient installation, and simple and reliable structure.

[0048] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0049] The above-described embodiments only represent the specific implementation manners of the present invention, and the description is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
