Detailed Implementation
[0011] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0012] Example like Figure 1 , Figure 2 As shown, Figure 1 The diagram shown is a three-dimensional representation of the extended components in the embodiment. Figure 1 ; Figure 2 The diagram shown is a three-dimensional representation of the extended components in the embodiment. Figure 2 ; The device includes a first box base 11 and a second box base 12 disposed on one side of the first box base 11. The first box base 11 and the second box base 12 have communicating cavities inside. A plurality of mounting holes 20 are provided at intervals on one end of the housing base 11 away from the housing base 22, and an RF connector 30 can be detachably inserted into the mounting holes 20.
[0013] Several radio frequency connectors 40 are arranged at intervals on the housing substrate 2 12.
[0014] RF connector 30 and RF connector 40 are connected by a cable, which is located inside the cavity of housing base 11 and housing base 22.
[0015] The expansion component serves as a carrier, enabling corresponding connections between multiple RF modules. The detachable RF connector 30 facilitates maintenance, replacement, or flexible configuration of the number of RF connectors 30 as needed.
[0016] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, Figure 3 The diagram shown is a cross-sectional view of the extended component in the embodiment; Figure 4 What is shown is Figure 3 A magnified schematic diagram of the structure at point B in the middle; Figure 5 The diagram shown is of RF connector one; Figure 6 The diagram shown is of the retaining ring; The radio frequency connector 30 includes an outer conductor 31, a fixing ring block 33 is provided on the outside of the outer conductor 31, a limiting groove is provided on the fixing ring block 33, an elastic retaining ring 34 is provided in the limiting groove, and an opening groove 341 is provided on the retaining ring 34 to provide deformation space for the retaining ring 34.
[0017] The limiting groove is used to accommodate and limit the retaining ring 34. The opening groove 341 enables the retaining ring 34 to expand outward and contract inward, which facilitates locking and releasing.
[0018] The mounting hole 20 is also provided with a step for the retaining ring 34 to be placed inside. In the initial state, the retaining ring 34 is in a naturally open state with a diameter larger than the inner diameter of the mounting hole 20. During the process of inserting the RF connector 30 into the mounting hole 20 (from bottom to top), an external force is first applied to the retaining ring 34, causing it to shrink inward, reduce its overall diameter, and enter the mounting hole 20. After the retaining ring 34 enters the mounting hole 20, it resets and causes the RF connector 30 to engage and be fixed in the mounting hole 20.
[0019] The outer surface of the retaining ring 34 is beveled. The beveled shape facilitates the insertion of an external tool clip between the outer wall of the retaining ring 34 and the inner wall of the mounting hole 20 during disassembly, thereby holding the retaining ring 34 and allowing it to retract so that the RF connector 30 can leave the mounting hole 20.
[0020] like Figure 6 , Figure 7 As shown, Figure 6 The diagram shown is of an RF connector. Figure 7 The diagram shown is a schematic of the insertion end of RF connector one; The RF connector 30 also includes a plug end 32 extending from the mounting hole 20. The plug end 32 includes a dielectric body 321 and an annular piece 322 spaced apart from each other. The annular piece 322 is deformable and has a plurality of clearance grooves 323 spaced apart along the circumferential direction on the annular piece 322.
[0021] When the plug-in end 32 is plugged into the outside, under the action of external pressure, the annular piece 322 can undergo elastic deformation in the radial direction. This deformation allows the plug-in end 32 to automatically adjust its position in the radial direction to adapt to the positional deviation of the mating interface.
[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
