摘要： A continuity tester for a lamp, coaxial, plug connector has a receptacle connector with first and second coaxial, annular receptacle contacts at a same axial spacing apart as power and ground contacts of the lamp connector for electrical engagement when plugged therein and, a probe contact engageable with only the power contact. First and second LEDs connect to a battery via first and second parallel circuits. A biasing resistor in the second circuit ensures that battery power is provided to only the first LED when a battery circuit is completed only by electrical engagement of the first contact and the probe contact with the power contact of the male coaxial connector to signal absence of a short circuit and to only the second LED when a circuit is completed also by engagement of the second tester contact with the ground contact of the lamp connector to signal a short circuit.

摘要翻译： 用于灯，同轴插头连接器的连续性测试器具有插座连接器，其具有第一和第二同轴的环形插座触头，该插座连接器具有与灯连接器的电源和接地触点相同的轴向间隔，用于当插入其中时用于电接合，并且探针接触 只能与电源接触。 第一和第二LED通过第一和第二并联电路连接到电池。 第二电路中的偏置电阻确保仅当第一LED仅通过第一触点的电接合和与阳同轴连接器的电源触点的探针接触而完成电池电路而仅提供给第一LED，因为信号不存在 通过第二测试器接触与灯连接器的接地触点的接合来发出短路，当电路完成时也仅仅是第二个LED。
