Description

Technical Field

[0001] This utility model relates to the field of radio frequency connector technology, and in particular to the SBMA-JJ hermetic radio frequency connector. Background Technology

[0002] Hermetic radio frequency connectors are commonly used in electronic devices to prevent the internal air pressure from communicating with the external environment. This hermetic seal protects internal chips or electronic components from oxidation and moisture damage. They are frequently used in aerospace products.

[0003] The existing patent CN202977920U describes the SBMA-JJ hermetic RF connector, which includes a socket and an insulator. The insulator is disposed within the glass sintered assembly housing, and the socket is disposed within the insulator. The hermetic RF coaxial connector provided by this utility model utilizes a glass sintered assembly to ensure the connector's hermeticity requirements and simultaneously achieves reliable contact between the socket and the inner conductor, thereby ensuring the connector's elastic contact and good signal transmission function. Furthermore, the connector incorporates a staggered design between the socket step and the glass sintered assembly step, and a gap between the socket step and the inner conductor of the glass sintered assembly at the insertion point. This achieves high impedance compensation during signal transmission, ensuring the connector has excellent RF transmission performance.

[0004] However, when using the existing patented SBMA-JJ hermetic RF connector, the connection between the connector and the fitting is threaded, which can cause the interface to loosen during long-term use, thus affecting the transmission of current or signals. Utility Model Content

[0005] The purpose of this invention is to provide the SBMA-JJ hermetic RF connector, which solves the problem mentioned above where the connector and the joint are threaded, causing the interface to loosen over time, thus affecting the transmission of current or signals.

[0006] To achieve the above objectives, this utility model provides an SBMA-JJ hermetic radio frequency connector, including an installation tube, a sealing tube, an anti-wear component, and a fixing component. The sealing tube is fixedly installed on the installation tube, the anti-wear component is installed on the installation tube, and the fixing component includes a fixing plate, a horizontal plate, a sliding rod, a clamping plate, and a rotating component. The fixing plate is fixedly installed on the installation tube, the horizontal plate is fixedly installed on the fixing plate, the sliding rod is installed on the horizontal plate and rotatably connected to the horizontal plate, the clamping plate is fixedly installed on the sliding rod, and the rotating component is installed on the fixing plate.

[0007] The rotating component includes a first extension plate, a second extension plate, a threaded rod, and a limiting component. The first extension plate is fixedly mounted on the fixing plate, the second extension plate is fixedly mounted on the clamping plate, the threaded rod is mounted on the second extension plate, and the threaded rod is threadedly connected to the second extension plate; the limiting component is mounted on the threaded rod.

[0008] The limiting component includes a limiting block and a throttle. The limiting block is fixedly installed on the threaded rod. The throttle is fixedly installed on the threaded rod and located at the end of the threaded rod away from the limiting block.

[0009] The wear-resistant component includes a rubber strip, a movable plate, and a telescopic component. The rubber strip is fixedly installed on the movable plate, and the movable plate is installed inside the mounting tube via the telescopic component.

[0010] The telescopic component includes a support plate and a telescopic spring. The support plate is fixedly installed inside the mounting tube. One end of the telescopic spring is installed on the movable plate, and the other end of the telescopic spring is installed on the support plate.

[0011] The SBMA-JJ hermetic radio frequency connector of this utility model has a fixing plate fixedly mounted on the mounting tube, a horizontal plate fixedly mounted on the fixing plate, a sliding rod mounted on the horizontal plate, and a clamping piece fixedly mounted on the sliding rod. When the connector is inserted into the mounting tube, the handle is rotated, causing the threaded rod to rotate on the second extension plate and the first extension plate, causing the second extension plate to abut against the first extension plate, and causing the limiting block to abut against the second extension plate, thus fixing the second extension plate onto the first extension plate and fixing the clamping piece to the mounting tube. This secures the connector and the mounting tube, preventing loosening and ensuring the transmission of current or signals. Attached Figure Description

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The first embodiment of this application is as follows:

[0019] Please see Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of the overall structure of the SBMA-JJ hermetic radio frequency connector according to the first embodiment of this utility model; Figure 2 This is a schematic diagram of the installation structure of the threaded rod according to the first embodiment of this utility model.

[0020] This utility model provides an SBMA-JJ hermetic RF connector, comprising an mounting tube 101, a sealing tube 102, an anti-wear component, and a fixing component. The fixing component includes a fixing plate 103, a horizontal plate 104, a sliding rod 105, a clamping plate 106, and a rotating component. The rotating component includes a first extension plate 107, a second extension plate 108, a threaded rod 109, and a limiting component. The limiting component includes a limiting block 110 and a throttle 111. This solution addresses the problem that, during the use of the hermetic RF connector, the threaded connection between the connector and the joint can cause loosening at the interface over time, affecting current or signal transmission. It is understood that this solution can be used in scenarios involving the interconnection of electronic devices and can also be used to solve the problem of anti-wear on the joint surface.

[0021] In this embodiment, the sealing tube 102 is fixedly installed on the mounting tube 101, the anti-wear component is installed on the mounting tube 101, and the fixing component is installed on the mounting tube 101, thereby preventing loosening and affecting the transmission of current or signals.

[0022] The fixing plate 103 is fixedly installed on the mounting tube 101, the horizontal plate 104 is fixedly installed on the fixing plate 103, the sliding rod 105 is installed on the horizontal plate 104 and is rotatably connected to the horizontal plate 104, the clamping plate 106 is fixedly installed on the sliding rod 105, and the rotating component is installed on the fixing plate 103. The fixing plate 103 is made of stainless steel. It works in conjunction with the clamping plate 106 to secure the connector 112 within the mounting tube 101. The horizontal plate 104 supports the sliding rod 105. The sliding rod 105 rotates on the horizontal plate 104, acting as a hinge. The clamping plate 106 is movably sleeved on the mounting tube 101 via the sliding rod 105, facilitating the fixing and removal of the connector 112. The rotating component fixes the fixing plate 103 and the clamping plate 106, securing the clamping plate 106 to the mounting tube 101. When the connector 112 is inserted into the mounting tube 101, the rotating component causes the clamping plate 106 to abut against the mounting tube 101 and fix it in place, thus securing the connector 112 and the mounting tube 101 and preventing loosening that could affect current or signal transmission.

[0023] Secondly, the first extension plate 107 is fixedly installed on the fixing plate 103, the second extension plate 108 is fixedly installed on the clamping plate 106, the threaded rod 109 is installed on the second extension plate 108, and the threaded rod 109 is threadedly connected to the second extension plate 108; the limiting component is installed on the threaded rod 109. The first extension plate 107 is made of stainless steel and is fixedly mounted on the fixing plate 103 by welding. The second extension plate 108 is fixedly mounted on the clamping plate 106 by welding. When the second extension plate 108 abuts against the first extension plate 107, the clamping plate 106 is fixed on the mounting tube 101. The threaded rod 109 is mounted on the first extension plate 107 and the second extension plate 108 and is threadedly connected to the first extension plate 107 and the second extension plate 108, so that the second extension plate 108 abuts against the first extension plate 107. The limiting component limits the movement of the threaded rod 109. Rotating the threaded rod 109 causes the second extension plate 108 to abut against the first extension plate 107, and the limiting component fixes the threaded rod 109 on the second extension plate 108, thereby causing the clamping plate 106 to abut against the mounting tube 101 and be fixed on the mounting tube 101.

[0024] Then, the limiting block 110 is fixedly installed on the threaded rod 109; the throttle 111 is fixedly installed on the threaded rod 109 and located at the end of the threaded rod 109 away from the limiting block 110. The limiting block 110 is made of stainless steel. The limiting block 110 limits the movement of the threaded rod 109 and fixes the second extension plate 108 on the first extension plate 107; the throttle 111 facilitates the rotation of the threaded rod 109; rotating the throttle 111 causes the threaded rod 109 to rotate on the second extension plate 108 and the first extension plate 107, causing the second extension plate 108 to abut against the first extension plate 107, and causing the limiting block 110 to abut against the second extension plate 108, thereby fixing the second extension plate 108 on the first extension plate 107.

[0025] When using the SBMA-JJ hermetic RF connector of this embodiment, the connector 112 is inserted into the mounting tube 101, and the throttle 111 is rotated to make the threaded rod 109 rotate on the second extension plate 108 and the first extension plate 107, so that the second extension plate 108 abuts against the first extension plate 107, and the limiting block 110 abuts against the second extension plate 108, fixing the second extension plate 108 on the first extension plate 107, and fixing the clip 106 on the mounting tube 101, thereby fixing the connector 112 and the mounting tube 101 to prevent loosening and affecting the transmission of current or signal.

[0026] The second embodiment of this application is as follows:

[0027] Please see Figure 3 ,in Figure 3 This is a schematic diagram of the installation structure of the rubber strip according to the second embodiment of this utility model.

[0028] The wear-resistant component provided by this utility model includes a rubber strip 201, a movable plate 202, and a telescopic component, wherein the telescopic component includes a support plate 203 and a telescopic spring 204.

[0029] The rubber strip 201 is fixedly mounted on the movable plate 202; the movable plate 202 is installed inside the mounting tube 101 via the telescopic member. The rubber strip 201 is made of rubber and serves to prevent wear on the surface of the connector 112; the movable plate 202 supports the rubber strip 201; the telescopic member allows the movable plate 202 to extend and retract; during the insertion of the connector 112 into the mounting tube 101, the connector 112 contacts the rubber strip 201, and under the action of the telescopic member, the movable plate 202 moves and resets, thereby protecting the outer surface of the connector 112.

[0030] Then, the support plate 203 is fixedly installed inside the mounting tube 101; one end of the telescopic spring 204 is installed on the movable plate 202, and the other end of the telescopic spring 204 is installed on the support plate 203. The support plate 203 supports the telescopic spring 204; the telescopic spring 204 is made of carbon spring steel, and the telescopic spring 204 causes the movable plate 202 to move; the connector 112 contacts the rubber strip 201, and under the action of the telescopic spring 204, causes the movable plate 202 to move and reset, thereby causing the connector 112 to engage inside the mounting tube 101.

[0031] In this embodiment, when the SBMA-JJ hermetic RF connector is used, during the process of inserting the connector 112 into the mounting tube 101, the connector 112 contacts the rubber strip 201, and under the action of the telescopic spring 204, the moving plate 202 moves and resets, thereby locking the connector 112 into the mounting tube 101 and protecting the outer surface of the connector 112 to prevent wear.
