Description

Technical Field

[0001] The present invention belongs to the technical field of positioning and installation of comprehensive aperture structures, and in particular relates to an assembly for high-precision installation of an array joint blind-plug antenna and back-end equipment. Background Art

[0002] Integrated aperture structures are widely used in the aerospace field. Their internal structures usually include composite skins, sandwich filling materials, antennas, antenna back-end equipment, metal / composite frame structures, etc. The main functions of the antenna in the integrated aperture are to transmit, receive, and search for data signals, while data processing, calculation, conversion, and integration depend on the equipment at the back end of the antenna.

[0003] The closer the antenna is to the skin surface, the higher the strength and accuracy of the antenna's receiving and transmitting signals. Therefore, the integrated aperture currently has a structural form in which the antenna is involved in the combined bonding of the skin, sandwich filling materials, metal, and composite frame structure. Since the antenna's back-end equipment is heavy and large in size, and its installation position has little effect on the antenna's function and performance, it is usually installed on the frame structure through fasteners. A circuit connection relationship needs to be established between the antenna and the device. The currently commonly used connection methods are cable connection and plug connection. Cable connection has no requirements for the installation location of the device and is intuitive and convenient to operate, but its connection stability is not high. Cable connection requires a larger space for line arrangement, and it is difficult to ensure the consistency of signal amplitude and phase; plug connection has higher stability and small space requirements, which can ensure high-quality signal transmission, but once the antenna is involved in the combined bonding of the integrated aperture, its connector position is usually buried in the main structure. At this time, the plug connection is more difficult, so it is called a blind plug antenna device. Under this form, the accuracy of the connector position is difficult to guarantee, and individual connectors are easily damaged. Therefore, an auxiliary structure is needed that can be adapted to plug connection and ensure high-precision installation during blind plugging. Summary of the Invention

[0004] The present invention addresses the problems of lack of reference, large installation errors, and repeated trial installations during the installation of blind-plug antenna equipment into a frame structure and docking with an antenna slot, which may lead to distortion or even failure of the antenna function. The invention provides a positioning and installation component for blind-plug antenna equipment with an array connector, thereby achieving fast and accurate one-time installation.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A positioning and mounting assembly for an array connector blind plug-in antenna device, comprising: The first frame adopts an open structure design and is used to fix the connector of the antenna; A positioning member, whose shape is adapted to the first frame, has two oppositely arranged positioning surfaces, one of which is provided with a simulated plug adapted to the connector on the first frame; The second frame adopts an open structure design and is used to fix the plug of the antenna. It is adapted to the first frame and is positioned through another positioning surface in the positioning piece.

[0006] As a further solution of the present invention: the two positioning surfaces are a first positioning surface and a second positioning surface, the first positioning surface is provided with an analog plug, and the second positioning surface is provided with a first positioning hole, which is aligned with the antenna connection hole on the second frame.

[0007] As a further solution of the present invention: a plurality of first positioning pins are further provided on the first positioning surface, which are adapted to the second positioning holes reserved on the first frame.

[0008] As a further solution of the present invention: the positioning member adopts a conical structure design, so the two side surfaces of the positioning member are inclined, and a plurality of positioning protrusions are distributed on the two side surfaces. The gap between the positioning protrusion and the inner wall of the first frame is 0.5 mm.

[0009] As a further solution of the present invention: sinking grooves are provided at both ends of the second positioning surface, and machined reference holes and machined reference surfaces are provided on the sinking grooves.

[0010] As a further solution of the present invention: the first positioning hole and the antenna connection hole on the second frame are positioned and aligned using a second positioning pin.

[0011] As a further solution of the present invention: a groove is further provided on the second positioning surface, and the side shape of the groove is adapted to the inner contour of the second frame web.

[0012] As a further solution of the present invention: there are multiple simulated plugs, and each simulated plug is provided with a clearance hole.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This application can accurately locate the installation position of the antenna device on the frame structure, thereby improving the installation positioning accuracy of the depth and coaxiality when the blind-plug antenna with a comprehensive aperture structure is docked with the device, reducing the number of docking trials during blind plugging, avoiding damage to the antenna connector, and ensuring stable signal transmission between the antenna and the device.

[0014] 2. This application has been well applied in the high-precision positioning and installation of comprehensive aperture structure antennas and equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is combined with Figure 1-3 The embodiments of the present invention are described in detail.

[0021] like Figure 1-3 As shown, the present invention provides a positioning and installation assembly for an array connector blind plug-in antenna device, which includes: The first frame 1 adopts an open structure design and is used to fix the connector of the antenna; The positioning member 2 has an outer shape adapted to the first frame 1 and has two oppositely disposed positioning surfaces, one of which is provided with a dummy plug 21 adapted to the connector on the first frame 1; The second frame 3 adopts an open structure design and is used to fix the plug of the antenna. It is adapted to the first frame 1 and is positioned by another positioning surface of the positioning member 2.

[0022] Preferably, the two positioning surfaces are a first positioning surface 22 and a second positioning surface 23 , the first positioning surface 22 is provided with a simulation plug 21 , and the second positioning surface 23 is provided with a first positioning hole 24 that is aligned with the antenna connection hole 31 on the second frame 3 .

[0023] Preferably, a plurality of first positioning pins 25 are further provided on the first positioning surface 22 , which are adapted to the second positioning holes 11 reserved on the first frame 1 .

[0024] Preferably, the positioning member 2 adopts a conical structure design, so the two side surfaces of the positioning member 2 are inclined, and a plurality of positioning protrusions 26 are distributed on the two side surfaces. The gap between the positioning protrusions 26 and the inner wall of the first frame 1 is 0.5 mm.

[0025] Preferably, sunken grooves are provided at both ends of the second positioning surface 23 , and machined reference holes 27 and machined reference surfaces 28 are provided on the sunken grooves.

[0026] Preferably, the first positioning hole 24 and the antenna connection hole 31 on the second frame 3 are positioned and aligned using a second positioning pin 4 .

[0027] Preferably, a groove 29 is further provided on the second positioning surface 23 , and the side shape of the groove 29 is adapted to the inner contour of the web of the second frame 3 .

[0028] Preferably, there are a plurality of dummy plugs 21 , and each dummy plug 21 is provided with a clearance hole 210 .

[0029] The specific method of use of the present invention is as follows: (1) After the antenna is bonded to the skin, the first frame 1, and the sandwich filling material, the relative position of the antenna and the first frame 1 is fixed. The positioning member 2 is assembled and positioned with the first frame 1. The positioning member 2 is pushed toward the antenna connector using the surrounding surface of the simulated plug 21 as a guide. The simulated plug 21 is provided with a plug clearance hole 210, so the antenna plug will not be damaged.

[0030] (2) The first positioning pins 25 on the first positioning surface 22 are precisely positioned with the antenna and the first frame 1 so that all the first positioning pins 25 can be inserted into the second positioning holes 11 reserved for the antenna and the first frame 1. At this time, the positioning member 2 has achieved precise coaxial positioning of the antenna plug.

[0031] (3) Continue to push the positioning member 2 inward until the first positioning surface 22 is tightly fitted with the mounting surface of the first frame 1. At this time, it can be determined that the positioning member 2 has achieved the deep and precise positioning of the antenna plug.

[0032] (4) Since there are multiple positioning surfaces on the positioning part 2, in order to avoid the problem of multiple constraint contradictions, the positioning protrusion 26 adopts a yielding design. Compared with the theoretical profile, it is retracted 0.5 mm. After the depth and coaxiality are accurately positioned, the gap between the positioning protrusion 26 and the profiles on both sides of the first frame 1 is measured to check the positioning correctness of the positioning part 2.

[0033] (5) Assemble the second frame 3 for mounting the antenna device with the first frame 1 and the positioning member 2, accurately position the first positioning hole 24 on the second positioning surface 23 and the antenna connection hole 31 preset on the second frame 3 through the second positioning pin 4, and continue to push the second frame 3 in until the mounting surface of the second frame 3 is tightly fitted with the second positioning surface 23 of the positioning member 2.

[0034] (6) Drill the connection holes for fixing the second frame 3 on the first frame 1, disassemble the second frame 3 and the positioning member 2, combine and install the antenna device and the second frame 3, and then install them together into the first frame 1. Use the connection holes between the second frame 3 and the first frame 1 to achieve the final installation and positioning.

[0035] So far, the purpose of the present invention has been achieved.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
