Description

Technical Field

[0001] This utility model specifically relates to a fixture for detecting the insertion and extraction force of an RF coaxial connector. Background Technology

[0002] A radio frequency (RF) coaxial connector is an interface element used to transmit radio frequency (RF) signals. It is typically attached to cables or mounted on instruments, achieving electrical connection and disconnection of the transmission system through the mechanical engagement and disengagement of the plug and socket. Its unique coaxial structure design enables efficient transmission of RF electromagnetic field signals.

[0003] After the production of RF coaxial connectors, it is necessary to determine whether the insertion and extraction force between the connector plug and socket meets the requirements. Currently, this is mostly done manually, which is not accurate enough and affects the later market application of the RF coaxial connectors. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for detecting the insertion and extraction force of an RF coaxial connector, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a RF coaxial connector insertion and extraction force detection fixture, comprising a frame, a socket positioning component, a plug positioning component, and an insertion and extraction force detection component. The socket positioning component is mounted on the frame via a positioning block, the plug positioning component is mounted on the frame via a movable seat, and the insertion and extraction force detection component is used to detect the insertion and extraction force after the plug is inserted into the socket.

[0006] Preferably, the socket positioning assembly includes a chuck disposed on the positioning block, and four slots are equally spaced around the chuck, with screws disposed in the slots.

[0007] Preferably, the slot is further provided with limiting blocks, and the four limiting blocks form a limiting area for fixing the socket, and the lower surface of the limiting blocks is provided with an internal thread that matches the outer thread of the screw.

[0008] Preferably, the plug positioning assembly includes a housing disposed on a movable base, a rotating shaft inserted into the housing, an installation head disposed at the end of the rotating shaft facing the socket positioning assembly, and a handle disposed at the end of the rotating shaft away from the installation head.

[0009] Preferably, the insertion / extraction force detection component includes a bearing housing mounted on the outside of the housing, a connecting rod disposed on the outside of the bearing housing, and a movable plate connected to the end of the connecting rod away from the bearing housing.

[0010] Preferably, the upper surface of the frame is provided with a protrusion, the protrusion is provided with a slide rail, and the lower surface of the movable plate is provided with a slide rod, the slide rod extending into the slide rail.

[0011] Preferably, the frame is further provided with a fixed plate, and a plurality of springs are provided between the fixed plate and the movable plate.

[0012] The technical effects and advantages of this utility model are as follows: This RF coaxial connector insertion and extraction force detection fixture places the connector socket between four limiting blocks. Rotating the screw causes the internal thread on the lower surface of the limiting blocks to engage with the external thread, driving the four limiting blocks closer together and clamping the socket in place. As the plug is inserted into the mounting head, rotating the handle drives the rotating shaft to rotate, allowing the plug and socket to reach a suitable insertion angle. With the movement of the movable base, the plug is inserted into the socket. At this time, a sliding rod slides along the length of the slide rail, causing the movable plate to move accordingly. Springs are used to engage between the fixed plate and the movable plate, increasing the number of springs to increase the pulling force on the plug after insertion. The insertion and extraction force of the RF coaxial connector can be judged and detected based on the spring force and the number of springs. The overall structure is simple, easy to use, and improves the practicality of detecting the insertion and extraction force of RF coaxial connectors. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] To improve the practicality of RF coaxial connector insertion and extraction forces, refer to Figure 1 , Figure 2 and Figure 3 As shown, the device includes a frame 1, a socket positioning assembly, a plug positioning assembly, and a insertion / extraction force detection assembly. The socket positioning assembly is mounted on the frame 1 via a positioning block 2, and the plug positioning assembly is mounted on the frame 1 via a movable seat 3. The insertion / extraction force detection assembly is used to detect the insertion / extraction force after the plug is inserted into the socket. The connector socket is placed between four limiting blocks 7. Rotating the screw 6 causes the internal thread 8 on the lower surface of the limiting block 7 to engage with the external thread, driving the four limiting blocks 7 closer together, thereby clamping and fixing the socket. As the plug is inserted into the mounting head 11, the screw 6 rotates... The handle 12 is turned to rotate the rotating shaft 10, so that the plug and socket are at a matching insertion angle. As the moving base 3 moves, the plug is inserted into the socket. At this time, the slide bar 18 slides along the length of the slide rail 17, causing the moving plate 15 to move accordingly. Springs 20 are used to fasten between the fixed plate 19 and the moving plate 15 respectively. The number of springs 20 is increased one by one, thereby increasing the pulling force on the plug after it is inserted into the socket. The insertion and extraction force of the RF coaxial connector can be judged and detected by the elasticity of the springs 20 and the number of springs 20. The overall structure is simple and easy to use.

[0023] To improve the stability of the socket during the testing process, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the socket positioning assembly includes a chuck 4 mounted on the positioning block 2. Four slots 5 are equally spaced around the chuck 4. A screw 6 is installed in each slot 5, and a limiting block 7 is also installed in each slot 5. The four limiting blocks 7 form a limiting area for fixing the socket. The lower surface of the limiting block 7 is provided with an internal thread 8 that matches the outer thread of the screw 6. As the screw 6 is rotated, the outer thread of the screw 6 engages with the internal thread 8 on the lower surface of the limiting block 7, thereby driving the limiting blocks 7 to move closer or further apart. The screw 6 is provided with two threads in opposite directions to facilitate the rotation of the screw 6 and control the movement of the limiting blocks 7. When the four limiting blocks 7 move closer together, the socket can be fixed. The plug positioning assembly includes a housing 9 disposed on a movable base 3. A rotating shaft 10 is inserted into the housing 9. An installation head 11 is provided at the end of the rotating shaft 10 facing the socket positioning assembly. A handle 12 is provided at the end of the rotating shaft 10 away from the installation head 11. The plug is placed on the installation head 11. The installation head 11 and the center of the limiting area formed by the four limiting blocks 7 are horizontally arranged. Therefore, after the plug is installed, it is only necessary to rotate the handle 12 to drive the rotating shaft 10 to rotate so that the plug and the socket are in a matching insertion direction. As the movable base 3 moves, the plug can be inserted into the socket. The insertion / extraction force detection component includes a bearing seat 13 mounted on the outside of the housing 9. Due to the bearing seat 13, when the rotating shaft 10 rotates, it does not cause the connecting rod 14 to rotate accordingly. A connecting rod 14 is provided on the outside of the bearing seat 13. A movable plate 15 is connected to the end of the connecting rod 14 away from the bearing seat 13. A protrusion 16 is provided on the upper surface of the frame 1, and a slide rail 17 is formed within the protrusion 16. A sliding rod 18 is provided on the lower surface of the movable plate 15, extending into the slide rail 17. The sliding rod 18... The slide plate 15 slides smoothly along the length of the slide rail 17 within the slide rail 17, improving the smoothness of its movement. The frame 1 is also equipped with a fixed plate 19, and several springs 20 are provided between the fixed plate 19 and the slide plate 15. When the plug is inserted into the socket, the slide plate 3 is close to the fixed block. At this time, the springs 20 are used to connect the slide plate 15 and the fixed plate 19 respectively. As the springs 20 are added one by one, the pulling force on the slide plate 15 can be increased. Different pulling forces are used to check whether the plug will fall out of the socket, thus realizing the detection of insertion and extraction force.

[0024] In use, first place the connector socket between the four limiting blocks 7, rotate the screw 6, and drive the four limiting blocks 7 to move closer together by engaging the internal thread 8 on the lower surface of the limiting block 7 with the external thread of the screw, thereby clamping and fixing the socket. Then, insert the plug into the mounting head 11, rotate the handle 12, and drive the rotating shaft 10 to rotate, so that the plug and socket are at a matching insertion angle. As the moving seat 3 moves, insert the plug into the socket. At this time, the slide rod 18 slides along the length of the slide rail 17, driving the moving plate 15 to move accordingly. Use springs 20 to fasten between the fixed plate 19 and the moving plate 15 respectively, and increase the number of springs 20 one by one, thereby increasing the pulling force on the plug after it is inserted into the socket. The insertion and extraction force of the RF coaxial connector can be judged and detected by the elasticity of the springs 20 and the number of springs 20.

[0025] 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.
