Abstract:
1. An electric cable connecting device comprising: a base member including a terminal post having an outer thread formed on said terminal post and having an orifice formed in said terminal post for engaging with an electric cable, an actuating device including a housing having a chamber formed in said housing, and a casing attached to said housing and having a non-circular compartment formed in said casing, a torque limiting mechanism including a follower rotatably engaged in said chamber of said housing and having an inner thread formed in said follower for engaging with said outer thread of said terminal post, and having a plurality of ratchet teeth provided on said follower, and a release member slidably engaged in said chamber of said housing and having a plurality of ratchet teeth for engaging with said ratchet teeth of said follower, said release member including a non-circular stud for slidably engaging with said non-circular compartment of said casing and for limiting said release member to slide relative to said housing and said casing and for preventing said release member from rotating relative to said housing, and a spring biasing member engaged between said release member and said casing for biasing said ratchet teeth of said release member to engage with said ratchet teeth of said follower, wherein said release member is forced to slide onto said spring biasing member and to move away from said follower with a sliding engagement between said ratchet teeth of said release member and said ratchet teeth of said follower when a torque applied to said housing and onto said terminal post is greater than a predetermined torque value of said spring biasing member, allowing said follower to be released.
