DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the present utility model will be further described below in conjunction with the embodiments and drawings.

[0026] In the description of the present utility model, "several" means an indefinite quantity, "multiple" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, the terms “comprises”, “includes” or any other variations thereof are intended to cover a non-exclusive inclusion, which may include other elements not explicitly listed in addition to the elements listed.

[0028] Most traditional phase shifter brackets are made of metal plates, which are connected by plastic clips and finally fixed to the antenna reflector with connecting metal plates and screws. However, the metal plate support frame increases the weight of the antenna, occupies a lot of space and affects the layout. The more metal structural parts inside the antenna, the more complicated the installation and the longer the installation time. Metal devices may also bring a problem. There are many burrs left in the metal components during processing, and the insulation is not in place, which will cause intermodulation stability problems.

[0029] In order to solve the technical problems in the background technology, the utility model improves the traditional fan-shaped phase shifter bracket, adopts an integrated fan-shaped phase shifter bracket, and combines multiple component devices into one device, which greatly reduces the occupied space, simplifies the installation process, improves efficiency, and saves manufacturing costs and installation costs.

[0030] like Figure 1 and Figure 2 As shown, the utility model provides an integrated sector-shaped phase shifter bracket, comprising a plurality of support frames 100;

[0031] The support frame 100 includes an integrally formed support plate 110, a cable clamp 120 and a pair of pins 130, wherein the cable clamp 120 is disposed at both ends of the upper surface of the support frame 100, and the pair of pins 130 is disposed at both ends of the lower surface of the support frame 100, and a plurality of the support frames 100 are stacked by the pair of pins 130;

[0032] A phase shifter 200 is disposed at the top of each of the support frames 100 ; the cable clamp 120 is used for allowing a cable to pass through and then be connected to the phase shifter 200 .

[0033] Common phase shifter brackets generally include a PCB support frame 100, a cable clamp 120, a support column buckle, and a fixing plate connected to the antenna reflector 300. When the phase shifter 200 is assembled in a stacked manner, it is fixed to the antenna reflector 300 by screws or connecting plate clamp screws. The traditional double-layer phase shifter 200 uses plastic components to stack and screws. It can be seen that the assembly antenna has many parts and is inconvenient to install.

[0034] This embodiment starts from the direction of design improvement, disassembles the traditional phase shifter bracket, and then re-designs it, wherein the upper surface of the support frame 100 and the cable clamp 120 are required to be almost on the same plane, and the upper surface of the PCB phase shifter 200 board and the cable are required to be flush, and the PCB phase shifter 200 board cannot be deformed, otherwise it will affect the performance. This embodiment integrates the support plate 110, the cable clamp 120, and the pin 130, eliminating the fixing plate and simplifying the assembly process. The improved phase shifter bracket of this embodiment is simple, light, easy to install, has good insulation performance, and is low in cost.

[0035] like Figure 3 and Figure 4 As shown, in some embodiments, the support plate 110 is provided with rivet holes 111 for installing rivets.

[0036] In some embodiments, through holes 112 for adapting to the terminals 210 of the phase shifter 200 are opened on both sides of the support frame 100 , and the through holes 112 are close to the cable clamps 120 .

[0037] Combination Figure 2According to different needs, the PCB phase shifter 200 has two forms: a terminal version and a pad version. After the cable passes through the cable clamp 120, it is connected to the terminal 210 of the phase shifter 200 or welded to the pad 220 of the phase shifter 200. In order to use the support frame 100 as a universal part of the small PCB phase shifter 200, the side of the cable clamp 120 close to the welding of the PCB phase shifter 200 is hollowed out downward to adapt to the phase shifter 200 with a terminal version. There are multiple versions of the phase shifter 200 with different circuits. Holes for installing rivets are reserved on the surface of the support plate 110, which can be used for a variety of small PCB phase shifters 200 and facilitate structural drawing.

[0038] The utility model is based on the form of a traditional phase shifter bracket, and designs an integrated sector-shaped phase shifter bracket suitable for multiple phase shifters 200 by disassembling and recombining its structure. The practicality and stability of the utility model are improved through some detailed designs, and the final product can be applied to antennas.

[0039] The utility model provides an integrated phase shifter bracket with high mechanical strength and toughness, high temperature resistance and wear resistance, and low manufacturing cost, which can be used for a long time in harsh environments; the embedded assembly mode is convenient for assembly and disassembly.

[0040] In some embodiments, an embedded buckle 131 is disposed at the bottom end of the pair of pins 130 , and a first buckle notch 132 is disposed at the top end of the pair of pins 130 , and the first buckle notch 132 is adapted to fit the embedded buckle 131 .

[0041] In some embodiments, an embedded cylinder 133 is further disposed at the bottom end of the pair of pins 130 , and a first cylindrical notch 134 is disposed at the top end of the pair of pins 130 , and the first cylindrical notch 134 is adapted to fit the embedded cylinder 133 .

[0042] In some embodiments, the integrated sector-shaped phase shifter bracket further includes an antenna reflector 300 , and the antenna reflector 300 is provided with a second buckle notch 310 adapted to the embedded buckle 131 .

[0043] In some embodiments, the antenna reflector 300 is provided with a second cylindrical notch 320 adapted to the embedded cylinder 133 .

[0044] In this embodiment, the support frames 100 are overlapped and fixed to the antenna reflector 300 by means of the pins 130, and the screw fixing method is replaced by the embedded buckle 131. The embedded buckle 131 is designed under the four sides of the bottom of the pins 130 to improve the stability of the support frames 100, and an embedded cylinder 133 is added near the embedded buckle 131, and a buckle notch and a cylinder notch are designed on the surface of the pins 130, so that the two support frames 100 can be combined more stably.

[0045] In some embodiments, there are four pairs of pins 130 in total, and the four pairs of pins 130 are disposed at corners around the support plate 110 .

[0046] In some embodiments, the support frame 100 is made of glass fiber reinforced POM material.

[0047] The utility model starts from the direction of integration, reduces the components in the assembly, uses POM+10% GF material to implement the improvement plan, and adapts to some characteristics of the traditional phase shifter 200 component. The POM+10% GF material is an acetyl (POM) copolymer product filled with 10% glass fiber, which has high mechanical strength and toughness, high temperature resistance and wear resistance, and low manufacturing cost.
