Detailed Description

As described in the background art, before the network transformer is put into use, the insertion loss of the network transformer needs to be tested by using a testing jig so as to meet the use requirement. The testing part is generally two and is respectively positioned on two sides of the body, one end of the testing part is connected with the flat cable, and the other end of the testing part penetrates through the through holes to be in one-to-one corresponding contact with the pins, so that signals of the pins are obtained, and the signals are transmitted through the flat cable.

However, the inventor finds that the conventional test fixture can only test one network transformer at a time, and the efficiency is low, so that the high-efficiency test requirement of an enterprise is difficult to meet. Based on this, the inventor has created a many stitch comprehensive test fixture for network transformer of this application.
