[0003] With the development of the market, there is an increasing demand for customized products with multiple varieties and small batches. Since multiple varieties and small batches of test pieces are not suitable for special automated test production lines, the testing of different types of products requires the replacement of a whole set of special tooling, which has poor flexibility; and the demand for small batch testing cannot reach the peak capacity of automation, resulting in excess test capacity and low production line utilization. At the same time, the early construction of the production line requires a lot of financial and material resources, and it is difficult to recover the cost in the short term. Usually, RF connector loading and unloading test tooling is used, but the loading and unloading process requires frequent removal of screws and welding of wires. The two test methods have strong compatibility for testing different types of products, but are not suitable for batch testing. Therefore, it is necessary to develop new test tooling.
