The ball head 22 is disposed in the socket 11. A ball housing passageway 14 passes through the ball housing 10; a ball pin passageway 25 passes through the ball pin 24, and a ball head passageway 23 passes through the ball head 22. The ball pin passageway 25, ball head passageway 23 and ball housing passageway 14 are in communication with each other for routing the cable 2 through the ball joint 1. A limiter may extend from an internal surface of the socket 11 having a passageway connected to the ball housing passageway 14.
