ABSTRACT:
An improved suspended line cable breakaway device includes a first body portion for connecting to a first end of a support cable and a second body portion for connecting to a second end of the support cable. The first body portion includes resilient fingers having nubs, which are releasably received by slots contained in a cavity wall of the second body portion. A biased spreader, slidably contained in a cavity in the second body portion, is displacable axially along the cavity by an external force along the support cable to urge the nubs outwardly such that the second body portion is disengaged from the first body portion, simultaneously disconnecting component lines of a first end of a suspended line from corresponding component lines of a second end of the suspended line. A shield protects the component line connections, which are spaced internal to the device, from the elements. One embodiment provides a breakaway device for a three-component line and a first modified embodiment provides a breakaway device for a four-component line. A second modified embodiment provides a breakaway device without internal component line connections.
