摘要： A printed circuit board has two contact areas on each surface near one end. The board is sandwiched between two halves of a shell to form a plug in such a way that the contact areas are exposed. The contact areas on one surface are nearer the exposed end than the contact areas on the other. The tip and ring conductors of a pair of wires in a test cord are connected, respectively, with the two contact areas which are nearer the exposed end. A keeper spring which is connected to the shield of the jumper cable, the ground potential, insures that the plug will be retained within a jack into which the plug is inserted by engaging a detent. The detent is connected to ground potential. The jack has two long electrical contacts and two short electrical contacts. The long electrical contacts engage the two contact areas which are farther away from the exposed end and the two short electrical contacts engage the nearer contact areas. A circuit housed within the plug insures that when the plug is inserted within a jack, a tracing lamp associated with the jack will flicker for a predetermined period.

摘要翻译： 印刷电路板在靠近一端的每个表面上具有两个接触区域。 板被夹在壳的两半之间以形成插头，使得接触区域被暴露。 一个表面上的接触区域比另一个表面上的接触区域更接近暴露端。 测试线中的一对导线的尖端和环形导体分别与更接近暴露端的两个接触区域连接。 与跳线电缆的屏蔽层连接的保持器弹簧，即接地电位，确保插头通过接合制动器而保持在插头插入插座中。 制动器连接到地电位。 插座有两个长的电触点和两个短的电气触点。 长电触头接合远离暴露端的两个接触区域，并且两个短电触头接合更近的接触区域。 容纳在插头内的电路确保当插头插入插座时，与插孔相关联的跟踪灯将闪烁预定时间。
