Electrical breakaway conductor
First Claim
1. In an electrical breakaway connector for electrical conductor systems between a pair of selectively interconnectable vehicles having a flexible conductor member attached to one vehicle and an electrical receptacle member mounted on the other vehicle, one of said members having elongated male terminals and the other member having elongated female terminals connectively receiving the one member male terminals upon non-rotative linear movement of said members toward each other to establish an electrical connection therebetween, the improvement comprising, an actuator body mounted on the flexible conductor member adjacent to the receptacle member, actuator means mounted upon said body movable between a first position non-interfering with the interconnected members and a second separation-inducing position, and a flexible lanyard having a first end connected to said actuator means and a second end connectable to the one vehicle, the length of the flexible conductor member being greater than the length of said lanyard whereby attachment of said lanyard second end to the one vehicle causes said lanyard to be tensioned to displace said actuator from said actuator first position to said second position disconnecting the members upon the vehicle separating prior to significant tension being applied to the conductor member, said actuator body including a fitting having terminals defined within the fitting and in electrical connection with the receptacle terminals, fitting receiving means defined on said actuator body, said receiving means including holding means for holding the fitting within said fitting receiving means and comprising a concave cradle defined on said actuator body, said holding means comprising a bridge extending over said cradle, and threaded fasteners releasably mounting said bridge upon said body.

Abstract
An actuator for use with electric conductor systems using push-to-connect fittings, especially suitable for tractor/semi-trailer connections employing an actuator body having linearly displaceable plungers mounted upon a flexible conductor fitting which separates the conductor fitting and receptacle upon the plungers extending. A lever operator mounted upon the actuator body is connected to a flexible lanyard of a length less than that of the electrical conductor whereby tensioning of the lanyard occurs before damaging tension can be applied to the conductor and lanyard tensioning extends the plungers to disconnect the conductor fitting and receptacle.

- 6. An electrical breakaway connector actuator for electrical conductor systems for a pair of selectively interconnectable vehicles having a flexible member attached to one vehicle and an electrical receptacle member mounted on the other vehicle, one of said members having elongated male terminals and the other member having elongated female terminals connectively receiving the one member male terminals upon non-rotative linear movement of said members toward each other to establish an electrical connection between the members, the flexible conductor member including an end having a fitting, terminals defined in the fitting for selective electrical connection with the receptacle terminals, the improvement comprising, an actuator body, a cradle defined on said actuator body for receiving the conductor fitting, a clamp mounted on said body adjacent said cradle for clamping the conductor fitting in said cradle, a pair of linearly movable plungers displaceably mounted on said body movable in the direction substantially parallel to the length of the members, terminals, said plungers each being movable between a retracted position clearing the receptacle, and an extended position engaging the receptacle member, said plungers being located on opposite sides of said cradle, lever means pivotally mounted upon said body operatively associated with said plungers for displacing said plungers from said retracted position to said extended position, and a flexible lanyard connected to said lever means and the one vehicle having a length less than the length of the flexible conductor whereby tensioning of said lanyard pivots said lever means to extend said plungers to engage the receptacle and disconnect a fitting within said cradle from the receptacle.
