Abstract:
A cable release apparatus, comprising:a housing; a latch mounted at one end of the housing, the latch having a central opening and a plurality of projecting members extending into the housing; a releasable connector mounted inside the housing; and an actuator disposed in the housing, the actuator having one end disposed in the central opening in the latch and another end in contact with the releasable connector, the actuator being movable between a first position prior to activation of the releasable connector and a second position when the releasable connector is activated; wherein the projecting members comprise inner wedged surfaces for engagement with an outer wedged surface on the actuator; and wherein prior to activation of the releasable connector, the latch is held in place by an interference fit between the projecting members and the housing, and when the releasable connector is activated, the projecting members are deflected by applying tension to the latch, thereby releasing the latch from the housing.
