Abstract
Abstract The invention relates to a structure including a cleat connector for providing an electrical connection between an insulated wire and a bifurcated terminal element of electrically conductive resilient material. The terminal element includes a pair of leaf-spring contact arms lying in a plane and defined by a centrally located slot therein having sharp edges and adjoining an enlarged entry opening. The width of the slot is less than the diameter of the metallic conductor of the wire so that when the wire is pressed into the slot, the wire insulation is cut through, and an electrical connection is established between the wire conductor and the terminal element. A clamping element is associated with the terminal element for gripping the insulated wire.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
214 words
A structure including a cleat connector for providing an electrical connection with an insulated wire, said connector comprising: a carrier plate; a flat bifurcated terminal element of electrically conductive resilient material mounted on said carrier plate, said terminal element including a pair of leaf-spring contact arms lying in a plane defined by a centrally located slot therein having sharp edges and adjoining an enlarged entry opening in the terminal element, said slot in the terminal element having a width which is less than the diameter of the metallic conductor of the wire so that when the wire is pressed into the slot, the wire insulation is cut through and an electrical contact connection is established between the wire conductor and the terminal element; and a clamping element attached to said carrier plate and associated with the terminal element for gripping the insulated wire; wherein the improvement comprises: said clamping element being constructed as an insulating member and having an open slot extending centrally with respect to a rectangular cross-sectional surface area thereof and vertically downward; said terminal element being fixedly disposed on said carrier plate at an angle offset by about 45° with respect to the slot in said clamping element; and said clamping element substantially enclosing the terminal element in its structural configuration.
