[0001] This utility model relates to the field of radio frequency connector technology, and in particular to a radio frequency connector with a shielding cover. Background Technology
[0002] Shielded radio frequency (RF) connectors are core components used in radio communication equipment, with a history dating back to the early 1970s. With advancements in RF technology, these connectors have undergone continuous technological and performance optimization, evolving from early solutions based on tuning circuits to modern integrated chip designs. The shield's function is to effectively reduce the impact of external interference on internal signals through physical barriers and electromagnetic shielding, ensuring communication quality and improving system stability. Their widespread use in mobile phones, IoT devices, and other fields makes them a crucial component for ensuring the reliability of radio communications.
[0003] The importance of shielded RF connectors in radio communication equipment is self-evident; however, the design limitation of their shields, which are not easily removable, poses a challenge to system reliability. This inconvenience stems primarily from limitations in the selection of shielding materials, structural design, and manufacturing processes, making rapid separation or repair difficult. This design flaw can lead to external interference affecting RF signals, reducing communication quality, increasing equipment maintenance costs, and shortening lifespan. Therefore, there is an urgent need to develop more maintainable solutions to ensure that RF connectors can operate stably and reliably in complex environments.
[0004] In response to this technical problem, this application proposes a radio frequency connector with a shielding cover. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a radio frequency connector with a shielding cover, enabling convenient removal of the shielding cover. This design simplifies the installation and disassembly process, improves operational efficiency, ensures connection stability, and the adjustable design enhances device adaptability and connection stability, making it particularly suitable for installing radio frequency equipment in complex working environments.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A radio frequency connector with a shield includes a connecting shell, an RF unit body mounted on the top of the connecting shell, a shield mounted on the top of the connecting shell, a pressing block slidably connected to the top of the shield, a locking block connected to the bottom of the pressing block via a mounting assembly, a mounting tube fixedly connected to the bottom of the connecting shell, an adjusting ring threadedly connected to the outer wall of the mounting tube, a support block connected to the bottom of the adjusting ring via a support assembly, and a plurality of data connection lines mounted on the bottom of the mounting tube.
[0008] Furthermore, the mounting assembly includes a pressing block fixedly connected to the bottom end of the pressing block, the bottom end of the pressing block being in close contact with the outer wall of the opposite end of the locking block, and a locking rod being rotatably connected to the front end of the pressing block.
[0009] Furthermore, a second reset spring is fixedly connected to the rear end of the lever, and the bottom end of the second reset spring is fixedly connected to the inner wall of the top of the shield.
[0010] Furthermore, a sliding block 1 is fixedly connected to the top side of the front end of the inner wall of the shield, and a sliding block 2 is fixedly connected to the bottom side of the front end of the inner wall of the shield.
[0011] Furthermore, a reset spring is fixedly connected to both the left and right ends of the card block, and the other end of the reset spring is fixedly connected to the inner wall of the bottom end of the shield. The opposite end of the card block is detachably connected to the inner wall of the top end of the connecting shell.
[0012] Furthermore, the support assembly includes a transition piece rotatably connected to the bottom end of the adjusting ring, and a support plate is rotatably connected to one end of each transition piece.

[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the radio frequency unit inside the connecting housing transmits electrical signals via a data connection line. During shielding installation, pressing the pressing block causes the squeezing block to push the locking block outwards, allowing the shielding cover to snap into the connecting housing for quick installation. The locking lever, under the action of the second return spring, is limited along the sliding groove, ensuring the pressing block's position is stable. Upon pressing again, the locking lever disengages from the sliding groove, the squeezing block retracts, and the first return spring pushes the locking block inwards, enabling convenient disassembly of the shielding cover. This design simplifies the installation and disassembly process, improves operational efficiency, and ensures connection stability.
[0016] 2. In this invention, rotating the adjusting ring moves it along the mounting tube, causing the adapter plate to press down on the first support plate, causing the second support plate and the first support plate to open outwards, pushing the support block to expand radially. This adjusting mechanism enables rapid installation and stable support of the connecting shell and the mounting tube, and is suitable for mounting holes of different sizes. Its adjustable design improves the adaptability of the equipment, simplifies the installation process, and enhances connection stability, making it particularly suitable for the installation of radio frequency equipment in complex working environments.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an RF connector with a shield, comprising a connecting shell 1, an RF device body 17 mounted on the top of the connecting shell 1, a shield 2 mounted on the top of the connecting shell 1, a pressing block 3 slidably connected to the top of the shield 2, a locking block 10 connected to the bottom of the pressing block 3 via an installation assembly, the installation assembly including a pressing block 15 fixedly connected to the bottom of the pressing block 3, the bottom of the pressing block 15 being in close contact with the outer wall of the opposite end of the locking block 10, a locking rod 9 rotatably connected to the front end of the pressing block 3, a second return spring 12 fixedly connected to the rear end of the locking rod 9, the bottom end of the second return spring 12 fixedly connected to the inner wall of the top of the shield 2, a sliding block 13 fixedly connected to the top side of the front end of the inner wall of the shield 2, a sliding block 14 fixedly connected to the bottom side of the front end of the inner wall of the shield 2, a first return spring 11 fixedly connected to both ends of the locking block 10, the other end of the first return spring 11 fixedly connected to the inner wall of the bottom end of the shield 2, and a locking block 10 detachably connected to the inner wall of the top of the connecting shell 1 at the opposite end.
[0026] Specifically: The radio frequency unit body 17 is surrounded by an electromagnetic shielding layer to reduce signal interference. A shielding cover 2 is fixed to the top of the connecting housing 1 via a detachable snap-fit mechanism. The shielding cover 2 is made of nickel-plated copper alloy to enhance electromagnetic shielding effectiveness. The top of the shielding cover 2 is equipped with a guide rail, which forms a sliding connection with the dovetail groove at the bottom of the pressing block 3. The bottom of the pressing block 3 is linked to the locking block 10 via an installation assembly. Specifically, when the pressing block 3 is pressed vertically, the wedge-shaped pressing block 15 at its bottom will push the locking blocks 10 on both sides outward along the inclined surface. The anti-slip teeth on the outer edge of the locking block 10 engage with the preset limiting groove on the inner wall of the connecting housing 1, realizing the rapid locking of the shielding cover 2. The two sides of the locking block 10 are connected to the inner wall of the shielding cover 2 by a high-elasticity return spring 11 to ensure automatic reset after the pressing is released. When the shielding cover 2 needs to be installed, the operator presses the pressing block 3, and the linkage mechanism drives the locking block 10 to overcome the elastic force of the return spring 11 and expand outward until it is locked into the annular locking groove at the top of the connecting housing 1. At this time, the locking rod 9 inside the pressing block 3, under the action of the second return spring 12, slides along the 45° inclined groove of the second slide block 14 into the positioning groove of the first slide block 13, forming a mechanical self-locking. During disassembly, a second pressing causes the locking rod 9 to disengage from the positioning groove, and the locking block 10 retracts under the action of the first return spring 11, realizing the rapid separation of the shielding cover 2. This design, while ensuring electromagnetic shielding effectiveness, achieves tool-free disassembly and assembly of the shielding cover 2, making it particularly suitable for base station equipment scenarios requiring frequent maintenance.
[0027] Reference Figure 2 and Figure 5The bottom of the connecting shell 1 is fixedly connected to the mounting tube 4. The outer wall of the mounting tube 4 is threadedly connected to the adjusting ring 5. The bottom of the adjusting ring 5 is connected to the support block 6 through the support group. Several data connection lines are installed at the bottom of the mounting tube 4. The support group includes the adapter plate 7 located at the bottom of the adjusting ring 5 and rotatably connected to the opposite end of the adapter plate 7. The opposite end of the adapter plate 7 is rotatably connected to the support plate 1 8. The upper and lower sides of the opposite end of the support block 6 are rotatably connected to the support plate 2 16. The opposite end of the support plate 2 16 is rotatably connected to the outer wall of the mounting tube 4. The opposite end of the support plate 1 8 is rotatably connected to the opposite end of the support plate 2 16.
[0028] Specifically: A tapered mounting tube 4 extends from the bottom of the connecting housing 1, and its outer wall is machined with precision threads, forming a helical transmission mechanism with the internal thread of the adjusting ring 5. The bottom of the adjusting ring 5 is connected to the support block 6 through a support assembly, which includes four sets of telescopic linkage mechanisms—the annular adapter plate 7 at the bottom of the adjusting ring 5 is hinged to four symmetrically distributed support plates 1-8, and the ends of support plates 1-8 are hinged to support plates 2-16, forming a variable angle support structure. When the adjusting ring 5 is rotated, it moves axially along the mounting tube 4, causing the parallelogram mechanism composed of support plates 1-8 and support plates 2-16 to unfold or retract, causing the support block 6 to produce radial displacement, thereby adapting to mounting holes of different diameters. The mounting tube 4 has an integrated waterproof sealing ring at its end, and four sets of gold-plated data connection cables are arranged in the bottom cable tray. A coaxial shielding structure ensures signal transmission stability. The RF unit body 17 and the data connection cables employ impedance matching design. The outer braided copper mesh shielding layer of the cable and the shielding cover 2 form a continuous electromagnetic shield, which, according to actual measurements, reduces electromagnetic leakage by 35dB in the 2.4GHz band. The adjustment mechanism of the support block 6 allows for an angle adjustment range of ±15°, and the rubber anti-slip pad design ensures stable installation of the connector on irregular equipment surfaces. Vibration testing has verified that this structure maintains a contact impedance of less than 5mΩ under random vibration conditions of 5-2000Hz, meeting the requirements of military standard MIL-STD-810G.
[0029] Working principle: The RF unit 17 installed inside the connecting housing 1 emits an electrical signal under the action of the data connection line for use. When the shielding cover 2 is installed at the connecting housing 1, pressing the pressing block 3 causes the squeezing block 15 to squeeze the locking block 10 to both sides, thereby squeezing the locking block 10 out of the shielding cover 2 and locking the shielding cover 2 inside the connecting housing 1, thus achieving installation between the connecting housing 1 and the shielding cover 2. Meanwhile, the locking rod 9 at the pressing block 3 is squeezed by the second return spring 12, causing the second return spring 12 to remain in an inclined state, so that the second return spring 12 is locked in the groove of the second slide block 14. The sliding block 3 is positioned within the groove of 13, thus limiting its movement. When the pressing block 3 is pressed again, the locking rod 9 slides out from between the sliding block 13 and the sliding block 14, allowing the pressing block 15 to retract. The reset spring 11 then presses the locking block 10, allowing the shielding cover 2 to be detached from the connecting housing 1. Rotating the adjusting ring 5 causes it to move along the mounting tube 4, causing the adjusting ring 5 to press down on the support plate 8 via the adapter plate 7, thus allowing the support block 6 to open outwards between the support plate 16 and the support plate 8. This facilitates the installation of the connecting housing 1 and the mounting tube 4 at the work location.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
