The insulator mainly plays a role in supporting and insulating, and is combined with the peripheral flange ferrule and the probe for transmitting signals through high-temperature vacuum brazing. Usually, when evaluating the performance of the feedthrough connector, one very important factor is the bonding strength between the signal transmission wire and the insulator in the feedthrough connector. Therefore, during the product verification process, it is necessary to conduct a pulling force test on the wire of the product. Considering that the self-weight of the feedthrough connector and the tooling will affect the accuracy of the measurement results, a horizontal measuring instrument can be used to avoid the influence of gravity. However, the existing pulling force test fixtures are not suitable for horizontal pulling force measuring instruments. Content of the Utility Model

First, place the feedthrough connector on the left fixture, lay one end of the wire flat on the left and right wire placement plates, and extend the other end of the wire into the right wire groove of the right fixture. Use a bolt to screw down vertically from the bolt hole of the fixing plate to press the wire tightly in the wire groove and fix it, then the tensile strength measurement can be carried out. After the test is completed, unscrew the bolt and take out the feedthrough connector. Using this device is convenient for measurement and has high measurement efficiency, which is suitable for batch testing of the same product. This utility model is used in conjunction with a horizontal tensile tester for measurement, avoiding the influence of gravity, making the test results accurate. The wire is placed on a fixed plane and passes through the wire groove, achieving the effect of fixing the wire and avoiding wire bending during the measurement process.
