Description

Technical Field

[0001] The utility model relates to a high-frequency array antenna in the technical fields of communication, measurement and control, and more particularly to a multi-channel SMP-KK vertical plug-in structure. Background Art

[0002] Currently, large-scale high-frequency array antennas mainly adopt a subarray design, which divides the entire array into multiple standard subarrays. Multiple subarrays are closely arranged according to the electrical design. Each subarray is interconnected with the back-end power amplifier module through the SMP. A subarray usually has dozens of SPM arrays. The pull-out force of each SMP is about 9N. When disassembling and replacing a subarray, the required pull-out force is large and there is no suitable fulcrum. Often, violent disassembly or disassembly from the edge to the subarray to be replaced is used, which is not conducive to on-site replacement and problem finding. It is meaningful to study an SMP-KK pull-out structure for arrays. Utility Model Content

[0003] The purpose of the utility model is to design a structure to realize vertical plugging and unplugging of SMPs of an array without damaging the antenna subarrays, and to facilitate portable assembly and disassembly of the subarrays.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An array SMP-KK lifting structure includes a high-frequency antenna array of an SMP structure, a structural fixing plate, a sub-array support plate, and a PCB printed circuit board;

[0006] The high-frequency antenna vibrator is provided in plurality and is welded on the surface of the PCB in an array form; the sub-array support plate is attached to the back of the PCB; the sub-array support plate is provided with a through hole a corresponding to the SMP, which is used to realize the electrical connection between the SMP and the back-end components;

[0007] The bonded sub-array support plate and PCB printed board are also provided with threaded holes and through holes b; screws are installed on the structural fixing plate through the through holes b of the sub-array support plate; when disassembling, the screws are threadedly matched with the threaded holes.

[0008] Compared with the prior art, the present invention has the following advantages:

[0009] 1. The number of SMP-KK sub-arrays can be adjusted at will;

[0010] 2. Currently designed for the Ku band, it can be extended to other frequency bands such as Ka and X. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] An SMP-KK lift-off structure for an array consists of a high-frequency antenna array with an SMP structure, a PCB for electrically interconnecting the array units, a sub-array support plate, and a structural fixing plate. The high-frequency antenna array is soldered to the PCB at specific intervals. Because the PCB lacks structural strength and cannot serve as a load-bearing component, the PCB is attached to the sub-array support plate as a whole. The sub-array support plate has an 8mm diameter through-hole reserved at the SMP interface to enable electrical interconnection between the SMP and back-end components.

[0018] The subarray support plate is evenly distributed with four threaded holes for extraction and four through-holes for fastening. Screws pass through the subarray support plate's through-holes and are installed on the structural mounting plate. If a subarray needs to be replaced, first remove the fastening screws, then screw them into the threaded holes in the subarray support plate. When the fastening screws pass through the subarray support plate, they will hit the end face of the structural mounting plate. As the fastening screws continue to rotate downward, the reaction force of the structural mounting plate pulls the subarray support plate away from the structural mounting plate, and the subarray support plate is bonded to the PCB. When the reaction force exceeds the subarray's SMP-KK extraction force, the subarray's SMP connector disconnects from the backend components. Because both the fastening screw force and the reaction force act on the structural components, the PCB is not subjected to any load, preventing structural damage to the subarray.

[0019] See also Figures 1 to 3 The antenna sub-array is pasted on the surface of the structural support plate. During normal operation, the sub-array support plate is installed on the structural fixing plate by screws. A through hole is reserved at the SMP connector position of the sub-array support plate and the structural fixing plate to ensure electrical interconnection between the antenna and the back-end components. When the sub-array is replaced, the threaded reaction force of the sub-array support plate is used to realize the SMP-KK plug-in and pull-out of the array. Figure 4 It is a Ku-band subarray antenna.

[0020] Brief working principle of this utility model

[0021] The working principle of an SMP-KK extraction structure for an array is to separate the SMP-KK by utilizing the reaction force of the threaded tightening force, thereby realizing the vertical disassembly and assembly function of the antenna subarray.

[0022] The present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
