Abstract
A connector assembly for use with a mining cable coupler includes a first connector and a second connector. The first connector includes a front portion including a plug and a rear portion including a barrel configured to receive a first conductor. The second connector includes a front portion including a socket having a channel defined therein and a rear portion including a barrel configured to receive a second conductor. An annular groove is defined in an inner surface of the channel. An annular spring held in the annular groove. The channel is sized and configured to receive the plug such that the plug resiliently contacts the spring to electrically connect the first conductor received in the first connector barrel and the second conductor received in the second connector barrel.
