Example of the Insertion Force Tester Test
The 1220SA plug-in force tester is not only capable of measuring the insertion force of a connector, but it also supports multiple testing functions such as break force test, constant tensile stress test, impedance test, single PIN retention test, and positive force test. Below are detailed operation instructions to guide users through each process. One: Insertion Force Test
1. Set the movement mode to bidirectional measurement with a speed range of 1–300 (standard machine speed). You can adjust the number of tests from 1 to 10,000,000. Make sure to "start measuring position" and check the origin once before beginning.
2. Insert the male and female connectors of the product into the clamps, ensuring that the clamps are vertical. The automatic centering device should be near the center position and must not be misaligned, as this could affect the automatic centering function or damage the device.
3. Apply load, reset to zero, and press the move button on the panel to separate the male and female ends slightly—without fully removing them. Observe the display to ensure smooth movement.
4. Set the test stroke, which should be less than the actual stroke by 0.1–0.2 mm.
5. After setting all parameters, click “File†and then “Pre-set Storage†to save the file. The file name should only include letters, numbers, periods, and hyphens—no spaces allowed.
6. Begin the screen test.
If the stroke cannot be found, use a height gauge to measure the insertion stroke of the male plug. Adjust the position of the connectors and set the stroke accordingly. Ensure the stroke does not exceed the measured value, and the starting position is critical for accurate results. Two: Break Force Test
1. Clamp the test product into either the upper or lower clamp and adjust the height so that the product is securely held.
2. Select the “Break Test†mode. Set the stroke based on the actual stroke of the product to ensure it can be completely pulled out.
3. Adjust the speed and number of cycles, then save the file.
4. Return to zero and re-clamp the product. Note: Do not return to zero after clamping.
5. Start the test. Three: PIN Retention Test
1. Connect the sensor interface to the test rod and lower the fixture to the appropriate position.
2. Set the load measurement range to be greater than the force required to withdraw the PIN. The stroke measurement range should be less than the distance from the PIN to the insulation surface to avoid missing the actual force value during the test.
3. Select “Load Zero Position†(only when the force starts to count) and archive the settings.
4. Perform the test.
Alternatively, you can set the movement mode to “Single-direction Measurement.†In this case, only a black return force curve will appear on the graph. Four: Constant Tension and Tensile Test
1. Choose the constant tension mode; the software will automatically open the “Force†and “Time†data windows. Enter the desired force and time values and save the file.
2. Clamp the product and adjust its position.
3. Begin the test. When the set force is reached, the timer will start and stop after the set time is completed.
For constant pull tests, the setup is similar, except there is no return stroke.
Note: These tests tend to be slower, typically around 30 seconds per cycle. Five: Longitudinal Force Test
1. Select the load zero position and enable “Origin Detection Each Time.†Set the unit to “gram.â€
2. Attach the test rod to the corresponding test head.
3. Adjust the position and perform the test to measure the stress at a specific stroke.
Some customers require the stress value at the bottom point of the stroke. In such cases, contact the after-sales technician for assistance with the millimeter instrument. Six: Load-Displacement Test
If you need to determine how much deformation occurs under a certain force or what force is needed to cause a certain displacement, follow these steps:
1. Set the load measurement range to the required force and ensure the stroke is large enough.
2. Select the load zero position and enable “Origin Detection Each Time.â€
3. Set the speed (usually around 30), number of tests, and save the file.
4. Begin the test and observe the waveform diagram. The maximum value (imax) represents the stroke you want to measure. Seven: Contact Resistance Test
1. Set the parameters as in the normal insertion force test.
2. Select the “Insertion Point Resistance†option in the last column of the measurement items.
3. Clamp the male and female connectors using the impedance test fixture.
4. Proceed with the test.
Additional tests such as anti-bending test, peel force test, displacement load test for switch contacts, constant tensile life test, and force value measurement at break can also be performed using the 1220SA model. Detailed operation methods are available upon request. Please note that the above procedures apply only to the 1220SA insertion force tester with a patent certificate. Http://news.chinawj.com.cn
