DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 5 A radio frequency coaxial connector detection device includes a base 1, an L-shaped placement seat 2 is fixedly installed on the base 1, an electric control cylinder 3 is fixedly installed on the base 1, a mounting rod 4 is fixedly installed on the output shaft of the electric control cylinder 3, and a push rod 5 is installed on the end of the mounting rod 4 away from the electric control cylinder 3 through a connecting component, a contact plate 6 is fixedly installed on the push rod 5, a scale 7 is horizontally fixedly installed on the placement seat 2, an L-shaped indicator rod 8 is fixedly installed on the upper end of the contact plate 6, and one end of the indicator rod 8 points to the scale 7.

[0025] The placement seat 2 is used to place the RF coaxial connector. During testing, the RF coaxial connector is placed on the placement seat 2 so that one end of the RF coaxial connector contacts one end of the placement seat 2 and the other end faces the contact plate 6. Then the electric control cylinder 3 is started, and the output shaft of the electric control cylinder 3 drives the mounting rod 4 and the push rod 5 to move in the direction of the RF coaxial connector, thereby driving the contact plate 6 close to the RF coaxial connector. At the same time, when the contact plate 6 moves, it will drive the indicator rod 8 to move together. When the contact plate 6 contacts one end of the RF coaxial connector, the electric control cylinder 3 is closed. At this time, the staff can judge whether the size of the RF coaxial connector is qualified by observing the scale on the scale 7 pointed to by the indicator rod 8, thereby realizing the detection of the size of the RF coaxial connector, avoiding the error caused by manual measurement, and making the detection data more accurate.

[0026] A clamping assembly for clamping the RF coaxial connector is symmetrically provided on the placement seat 2, and the clamping assembly includes a support block 10 fixedly mounted on the placement seat 2, a moving rod 11 horizontally slidably mounted on the support block 10, a connecting block 12 fixedly mounted at one end of the moving rod 11, a clamping block 13 fixedly mounted at the other end of the moving rod 11 and a second telescopic spring 14 sleeved on the moving rod 11, and the two ends of the second telescopic spring 14 are respectively fixedly connected to the support block 10 and the connecting block 12.

[0027] Under the action of the elastic force of the second telescopic spring 14, the moving rod 11 and the clamping block 13 tend to move away from the electric control cylinder 3. When the RF coaxial connector is placed on the placement seat 2, the moving rod 11 will drive the clamping block 13 to move toward the RF coaxial connector until the clamping block 13 contacts one end of the RF coaxial connector. The RF coaxial connector is stably clamped on the placement seat 2 through the two clamping blocks 13 and one end of the placement seat 2, thereby avoiding the position of the RF coaxial connector from being offset during detection, affecting the detection results.

[0028] A rectangular plate 15 is fixedly sleeved on the mounting rod 4, and pull ropes 16 are fixedly installed at both ends of the rectangular plate 15. One end of the two pull ropes 16 is fixedly connected to the two clamping blocks 13 respectively. After the detection is completed, when the electric cylinder 3 drives the mounting rod 4 away from the RF coaxial connector, it will drive the rectangular plate 15 to move together, and then drive the clamping block 13 away from the RF coaxial connector through the pull rope 16, thereby releasing the clamping of the RF coaxial connector.

[0029] A movable groove is provided at one end of the push rod 5 close to the mounting rod 4. The connecting assembly includes a first telescopic spring 9 fixedly mounted at one end of the mounting rod 4. The end of the first telescopic spring 9 away from the mounting rod 4 is fixedly connected to the inner wall of the movable groove. One end of the mounting rod 4 is horizontally slidably mounted in the movable groove. A pressure sensor 17 is fixedly mounted on the rectangular plate 15 (the pressure sensor 17 is a prior art and will not be described in detail here). The pressure sensor 17 is electrically connected to the electronically controlled cylinder 3. A top block 18 is fixedly mounted at one end of the push rod 5. One end of the top block 18 points to the pressure sensor 17. The push rod 5 can When one end of the mounting rod 4 moves horizontally and the contact plate 6 contacts one end of the RF coaxial connector, the mounting rod 4 can move one end distance in the movable groove opened at one end of the push rod 5, and the first telescopic spring 9 is compressed to play a buffering role. At the same time, the top block 18 installed on the push rod 5 will move toward the pressure sensor 17 until the top block 18 contacts the pressure sensor 17. At this time, the pressure sensor 17 will turn off the electric control cylinder 3 to prevent the electric control cylinder 3 from continuing to drive the mounting rod 4 to move, and prevent the contact plate 6 from excessively squeezing the RF coaxial connector, thereby protecting the RF coaxial connector.

[0030] A protective pad is fixedly installed on one end of the contact plate 6 close to the placement seat 2. The protective pad is a rubber pad. When the contact plate 6 contacts the RF coaxial connector, the protective pad can protect one end of the RF coaxial connector and prevent one end of the RF coaxial connector from being worn.

[0031] In the present invention, during detection, the RF coaxial connector is placed on the placement seat 2, so that one end of the RF coaxial connector contacts one end of the placement seat 2 and the other end faces the contact plate 6, and then the electric control cylinder 3 is started, and the output shaft of the electric control cylinder 3 drives the mounting rod 4 and the push rod 5 to move in the direction of the RF coaxial connector, thereby driving the contact plate 6 close to the RF coaxial connector. At the same time, when the contact plate 6 moves, it will drive the indicator rod 8 to move together. When the contact plate 6 contacts one end of the RF coaxial connector, the electric control cylinder 3 is closed. At this time, the staff can judge whether the size of the RF coaxial connector is qualified by observing the scale on the scale 7 pointed to by the indicator rod 8, thereby realizing the detection of the size of the RF coaxial connector, avoiding the error caused by manual measurement, and making the detection data more accurate.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
