[0002] The installation method of SMA RF coaxial connector and equipment installation panel is usually flange installation. The existing installation method of SMA flange-mounted RF coaxial connector and installation panel is screw-fastened installation, that is, the connector is inserted into the silicone rubber sealing gasket and then inserted into the installation panel, and then the installation screws are screwed into the flange screw holes of the connector.

[0034] Specifically, it includes an installation panel 1, a connector assembly 2, and an insulating sealing assembly 3; the connector assembly 2 is connected to the installation panel 1 through the insulating sealing assembly 3, at least one set of connector assembly 2 is arranged on the installation panel 1, and the insulating sealing assembly 3 can seal and insulate the installation panel 1 and the connector assembly 2.

[0035] Furthermore, the connector assembly 2 includes a support member 21 , a connecting member 22 , and a fixing member 23 ; the connecting member 22 is mounted on the support member 21 , and the support member 21 and the mounting panel 1 are mounted via the fixing member 23 .

[0037] Furthermore, at least two groups of connecting members 22 are installed on the supporting member 21 .

[0038] Furthermore, the support member 21 includes a flange 211, a first fixing hole 212, and a second fixing hole 213. The flange 211 is provided with the first fixing hole 212 and the second fixing hole 213. A connecting member 22 is provided between the first fixing hole 212 and the second fixing hole 213. The fixing member 23 can be inserted into the first fixing hole 212 and the second fixing hole 213.

[0039] Preferably, the flange 211 can be fixed on the installation panel 1 by means of a fixing member 23 .

[0040] Furthermore, the connector 22 includes an SMA RF coaxial connector 221 . The SMA RF coaxial connector 221 is disposed on the flange 211 , and a plurality of groups of SMA RF coaxial connectors 221 can share a group of flanges 211 .

[0041] Preferably, only one set of SMA RF coaxial connectors 221 can be installed on the conventional flange 211. If two sets of SMA RF coaxial connectors 221 are installed, interference will occur. The length of the two sets of flanges 211 in the prior art is 34MM, while the length of the flange in our technical solution is 26.8MM, and two sets of SMA RF coaxial connectors 221 are installed on the limited flange, which saves space and avoids interference between the SMA RF coaxial connectors 221 and the fixing parts 23. Taking the installation of two sets of SMA RF coaxial connectors 221 on the flange 211 as an example, two sets of fixing parts 23 are reduced, thereby reducing the cost of use.

[0048] Furthermore, the anti-product shrinkage needle insulator 2211 can support and limit the central conductor 2212.

[0049] Preferably, the smaller the fitting tolerance of the SMA RF coaxial connector 221, the better the coaxiality, and the better the electrical performance of the product in the high frequency band. The SMA RF coaxial connector 221 is also provided with a bell mouth, which can make product assembly more convenient and improve assembly efficiency.

[0050] Preferably, temperature changes and repeated bending during the use and storage of the cable will cause the cable to pull out. Due to the structural and frequency relationship limitations of the RF connector, the bending and temperature requirements during use are regulated. Therefore, this product adds a PEI material anti-product shrinkage insulator 2211 under the center conductor 2212. This can effectively ensure that the center conductor 2212 is not displaced due to usage problems during the use of the product, causing the connector interface to exceed the standard requirements and thus affecting the electrical performance of the product.
