B2B connector in-place assembly detection device

The invention provides a B2B connector in-place assembly detection device simple in structure, low in cost, fast in testing and capable of predicting whether the connection assembly is in place correctly. The device comprises a comparison reference voltage source (1), two comparators (2), an AND gate (3) and an inverter (4), wherein the comparison reference voltage source (1) inputs two differentvoltages into the two comparators (2) respectively; the output ends of the two comparators (2) are connected to the AND gate (3); the AND gate (3) and the inverter (4) are connected to each other; theinverter (4) outputs a test result; and test probes (5) extend from the inverting ends of the two comparators (2) and are connected to metal pieces on both ends of a B2B connector to be tested respectively. The device can be used in the field of testing. 本发明提供了一种结构简单、成本低、测试快速且能够提前预警连接装配是否正确到位的B2B连接器装配到位检测装置。本发明包括比较基准电压源（1）、两个比较器（2）、与门判断（3）以及反相器（4），所述比较基准电压源（1）分别输入两个不同的电压到两个所述比较器（2），两个所述比较器（2）的输出端与所述与门判断（3）连接，所述与门判断（3）与所述反
