Description

[0002] Insertion and extraction force measurement is usually used to detect the force required for the insertion and extraction of connectors, plugs, sockets and other components. By measuring these forces, the mechanical properties and durability of the product can be evaluated to prevent problems such as loosening and falling off during use, which may affect the normal use and safety of the product.

[0003] The existing plug-in and pull-out force measurement methods all have some major and minor drawbacks. When manually using a dynamometer to measure the product to be tested, the accuracy depends on the worker's reading, which has poor accuracy and is time-consuming and labor-intensive. Secondly, during the test, it cannot be guaranteed that the dynamometer and the product to be tested are on the same horizontal line, and the plug-in and pull-out force speed cannot be stable and controllable. In addition, the use of a dynamometer measurement method during the measurement process also increases the source of error: First, the error caused by the long-term use of the dynamometer leads to an unreasonable range and affects the true value of subsequent measurements; second, the visual fatigue caused by the worker's frequent observation of the dynamometer value during the measurement process will also lead to inaccurate readings and affect the measurement value.

[0004] Therefore, how to provide an automatic plugging and unplugging force detection device that can accurately control the plugging and unplugging speed and direction and can accurately read the readings and an automatic plugging and unplugging force detection system using the device is a problem that technical personnel in this field urgently need to solve.

[0048] The right angle bracket 4 is mounted on the guide rail slider 3, with one side parallel to the guide rail slider 3 and the other side parallel to the horizontal plane;

[0049] Considering that the position deviation of the pin has a great influence on the system test result, the present invention is provided with a fine-tuning slide, and the fine-tuning slide 5 is installed on the side of the right-angle bracket 4 parallel to the horizontal plane, and is used for X and Y bidirectional fine-tuning, and is used to eliminate the position deviation in the X and Y directions;
