The characteristics of the patented insertion force load curve machine. Since the patents of the two 1220S connector insertion force test machines and S205 load curve test machine have been obtained in 2006, they have achieved good results in the domestic market. The patent numbers are 200620057696.2, 200620061119.0. It can be found on the National Intellectual Property Office/Website. At the time, when we applied for a patent, our company took into account the practicality of the two test machines, so we applied for a utility model patent (a utility model refers to a new and practical one for the shape, structure or combination of products). Technical solutions). In view of the strong domestic imitation ability (in fact, many friends asked us why we didn't look for those imitations to go to court, but we looked at the lawsuits of many intellectual property rights in China, basically won the lawsuit and lost money), so it is very good in appearance. It is difficult to distinguish the difference between a patented product and a generic product, so a more professional identification can be started as follows: GUOLONG PRECISION VALVE CO.,LTD , https://www.glstovevalve.com
1. Sensor protection against fools. Generally, such test machines cannot be manually operated before the test procedure is started. The protection must be confirmed before operation. Manually operate the test machine and the upper and lower fixtures collide together, and the test machine can automatically stop. This is to show that the test machine has a foolproof protection function. Suppliers must be face-to-face verified. Secondly, the other verification is that when the sensor is damaged, when the test machine is down, the test opportunity automatically moves up. This is the action that protects the mechanical part of the test machine. If the test machine can still go down, because the sensor is damaged and there is no force to protect the rebound, the test machine will go down according to the operation command, resulting in damage to the transmission part.
2. Verify its speed. Generally, there are many domestic test machines that can't reach the highest speed at most, which is 200mm/min, but only 150mm/min. The verification method is very simple. Set the speed of 200. Vertically put a lever to see if the displacement of the crossbar moves for 30 seconds. The servo motor can reach a speed of at least 300mm/min. Because the general supplier does not want to disassemble to see the configuration, this is a way to indirectly verify its configuration.
3. Look at the test program running, set the stroke test, and observe whether the walking stroke is exactly the same as the set stroke. There can be no drift deviation, and the return trip can be zero. After the end of the action, the test machine interface shows whether the stroke is zero.
4, observe the test program function, because this type of test machine can not only test the insertion force, but also constant tensile test, constant pressure test, broken test. Can replace the general tensile tester function. It is also possible to set a powerful metering stroke (a simple test such as testing a button spring, a longitudinal force test of the connector). You can also ask the supplier to make some minor changes. If you can't agree, the software is externally purchased without development capability.
5, by the way you can observe the connection line between the host and the computer, generally have 30 pins and two wires of 60 pins or more, can not be a simple R232 interface connection. If it is a simple connection, it means that the hardware configuration of the acquisition card and the control card is too simple, sampling the data stream, the sampling rate can not meet the requirements of this test machine. (Travel accuracy requirements, sensor protection is required quickly)
6. Whether the software provides open calibration and cannot have password control. This is now reflected in the market. I used to buy those imitations. Now the sensor is broken and the original supplier price is expensive. Look for us but no password calibration. (Previously the supplier provided the password to the customer, but that was the initial password).
Throughout the above points, the customer can distinguish the difference between the imitation plug-in force load curve meter and the patent insertion force load curve meter. After all, there is a certificate issued by the state authority, which is more credible and credible than the oral presentation.
