Description

Technical Field

[0001] This utility model relates to the field of testing tool technology, and in particular to a rotatable testing connector. Background Technology

[0002] Connector bases for plug-in boards are commonly used to connect gold finger type circuit boards. Currently, after the gold finger circuit board is connected to the connector, it is placed flat on the table for testing. If the signal to be measured simultaneously is located on both sides of the circuit board, the signal point to be measured must first be clamped on side A of the circuit board with a test clip, and then flipped to side B of the circuit board to clamp the signal point to be measured with another set of test clips. At this time, the test clips are between the circuit board and the table. In addition, the components on the circuit board are of different heights, which can easily cause the circuit board to wobble during testing. At the same time, the test clips are prone to shifting and hitting components on the circuit board, or the test clips may become loose and fall off, resulting in inaccurate test results or short circuits or even burnout of the circuit board. To avoid the problem of inaccurate test results caused by the test clips wobble between the circuit board and the table, two people need to operate simultaneously: one person stands the board upright and fixes it, and the other person clamps the signal point for testing.

[0003] However, this type of test, which involves two people working together, still has the following problems: the test process is time-consuming and labor-intensive, the test is inflexible, the test efficiency is low, and it is difficult for a single person to complete the test quickly. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this utility model provides a rotatable test connector. By installing a damping hinge between a flat plate and a U-shaped plate, a person can rotate the U-shaped plate installed on one side of the top of the flat plate, causing the plug-in board connector body installed on the inner side of the top of the U-shaped plate to rotate a certain angle and stop. If it is necessary to measure the A and B sides of the gold finger circuit board body at the same time, first rotate the U-shaped plate to the A side of the circuit board and stop, then select the signal point and place the test clip. Then rotate it to the B side of the circuit board and stop, select the signal point and place the test clip. The damping hinge can flexibly adjust the angle, which is convenient for testing the corresponding signal points of the A and B sides of the circuit board. Moreover, a single person can complete the test, which improves the testing efficiency.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a rotatable test connector, including a flat plate, a U-shaped plate disposed on one side of the top of the flat plate, and damping hinges respectively installed at both ends of the connection between the flat plate and the U-shaped plate.

T-shaped holes are respectively formed on the opposite surfaces of the first and second L-shaped mounting plates. The second L-shaped mounting plate is mounted to one side of the bottom U-shaped plate by a first screw, and the first L-shaped mounting plate is mounted to one side of the top of the flat plate by a second screw. Threaded holes are symmetrically formed on the surface where the first and second L-shaped mounting plates connect. One end of the threaded damping shaft extends through the threaded holes formed on the surfaces of the second and first L-shaped mounting plates, reaching the first L-shaped plate. A damping spring is fitted onto the outer surface of the L-shaped mounting plate. A hexagonal nut is fitted onto the outer surface of one end of the threaded damping shaft that passes through the damping spring. Limiting rings are fixedly installed on both sides of the first L-shaped mounting plate. One end of the damping spring is limited and installed on the limiting ring surface of the first L-shaped mounting plate on the side away from the second L-shaped mounting plate. A U-shaped groove is opened on the top surface of the U-shaped plate. Mounting grooves are symmetrically opened on opposite sides of the U-shaped plate near the U-shaped groove. I-shaped mounting holes are symmetrically opened on the outer surface of the U-shaped plate on one side of the two mounting grooves. A clamping block is installed at the top of the I-shaped mounting hole. A U-shaped locking block is fixedly installed on one side of the bottom end of the clamping block. A plug-in board connector body is limited and installed inside the U-shaped locking block. A gold finger circuit board body is connected to the pin side surface of the plug-in board connector body. The pin side surface of the plug-in board connector body is located inside the U-shaped groove.

[0006] As a preferred technical solution of this utility model, a square sleeve is fixedly provided on the bottom surface of the clamping block away from the U-shaped block. A through hole is opened on the surface of the clamping block near the square sleeve. The through hole is connected to the square sleeve. A screw is installed inside the through hole. A square limiting block is fixedly provided at the bottom end of the screw. A locking nut is sleeved on the surface of the top end of the screw, which passes through the I-shaped mounting hole, the square sleeve, and the through hole in sequence.

If it is necessary to measure the A and B sides of the gold finger circuit board body at the same time, first rotate the U-shaped plate to the A side of the circuit board and stop. At this time, select the signal point and place the test clip. Then rotate it to the B side of the circuit board and stop. Select the signal point and place the test clip. The damping hinge can flexibly adjust the angle, which is convenient for testing the corresponding signal points of the A and B sides of the circuit board.

The first L-shaped mounting plate 4 and the second L-shaped mounting plate 5 have symmetrically arranged threaded holes on their connecting surfaces. One end of the threaded damping shaft 3 passes through the threaded holes on the surfaces of the second L-shaped mounting plate 5 and the first L-shaped mounting plate 4, extending to the outer surface of the first L-shaped mounting plate 4, where a damping spring 21 is fitted. A hexagonal nut 6 is fitted on the outer surface of the end of the threaded damping shaft 3 that passes through the damping spring 21. Limiting rings 20 are fixedly installed on both sides of the first L-shaped mounting plate 4. One end of the damping spring 21 is limited and installed on the surface of the limiting ring 20 of the first L-shaped mounting plate 4 on the side away from the second L-shaped mounting plate 5. A U-shaped groove 7 is formed on the top surface of the mold plate 2. A mounting groove 8 is symmetrically formed on the opposite sides of the U-shaped plate 2 near the U-shaped groove 7. I-shaped mounting holes 9 are symmetrically formed on the outer surface of the U-shaped plate 2 on one side of each mounting groove 8. A clamping block 10 is mounted on the top of the I-shaped mounting hole 9. A U-shaped locking block 13 is fixedly set on one side of the bottom of the clamping block 10. A plug-in board connector body 11 is mounted and limited inside the U-shaped locking block 13. A gold finger circuit board body 12 is connected to the pin side surface of the plug-in board connector body 11. The side surface of the plug-in board connector body 11 away from the pins is inside the U-shaped groove 7. Through the flat plate 1 and the U-shaped... A damping hinge is installed between the two plates. Personnel can rotate the U-shaped plate 2 installed on one side of the top of the flat plate 1, so that the plug-in board connector body 11 installed on the inner side of the top of the U-shaped plate 2 rotates a certain angle and stops. If it is necessary to measure the circuits on the A and B sides of the gold finger circuit board body 12 at the same time, first rotate the U-shaped plate 2 to the A side of the circuit board and stop. At this time, select the signal point and place the test clip. Then rotate it to the B side of the circuit board and stop. Select the signal point and place the test clip. The damping hinge can flexibly adjust the angle, which is convenient for testing the corresponding signal points on the A and B sides of the circuit board.

Personnel can connect and fix the U-shaped plate 2 to the flat plate 1 by damping hinges. By rotating the U-shaped plate 2, the plug-in board connector body 11 can rotate and stop at any position. After the gold finger circuit board is connected to the plug-in board connector body 11, the U-shaped plate 2 can also rotate arbitrarily, making the corresponding signal point testing of the circuit board AB flexible and easy to adjust.

[0021] like Figure 1 , Figure 3 As shown, a square sleeve 17 is fixedly installed on the bottom surface of the clamping block 10 away from the U-shaped locking block 13. A through hole 14 is opened on the surface of the clamping block 10 near the square sleeve 17, and the through hole 14 is connected to the square sleeve 17. A screw 15 is installed inside the through hole 14. A square limiting block 19 is fixedly installed at the bottom of the screw 15. A locking nut 16 is sleeved on the top of the screw 15, passing through the I-shaped mounting hole 9, the square sleeve 17, and the through hole 14 in sequence. A limiting spring 18 is sleeved on the surface of the screw 15 inside the square sleeve 17.

[0023] like Figure 4 As shown, an adjusting block 22 is fixedly installed on the surface of the threaded damping shaft 3 near the hexagonal nut 6; by fixing the adjusting block 22 on the surface of the threaded damping shaft 3 near the hexagonal nut 6, it is convenient for personnel to rotate the adjusting block 22 to adjust the tightness of the threaded damping shaft 3.

[0024] like Figure 1 As shown, the bottom surface of the flat plate 1 is uniformly provided with anti-slip textures; by uniformly providing anti-slip textures on the bottom surface of the flat plate 1, the anti-slip properties of the bottom of the flat plate 1 are increased.

[0025] like Figure 1 , Figure 2 As shown, the square limiting block 19 is located inside the bottom end of the I-shaped mounting hole 9, and the square sleeve 17 is located inside the top end of the I-shaped mounting hole 9. By installing the square sleeve 17 and the square limiting block 19 at the top and bottom ends of the I-shaped mounting hole 9 respectively, the personnel can limit the clamping block 10 to the designated position of the I-shaped mounting hole 9, which facilitates the personnel to wire one side of the plug-in board connector body 11.
