The patent US12015218B2 describes a cable locking device designed for securely connecting two electrical wires. The device consists of two main parts: a first part with a longitudinal axis featuring a cavity for the first electrical wire and a projection with a tapered convex surface, and a second part that includes a cavity for the second electrical wire and a corresponding cavity designed to receive the projection. The connection mechanism involves a pin extending from the projection, which fits into channels within the second part. This design allows the pin to slide longitudinally and twist within the channels, creating a frictional engagement that secures the connection between the two parts. The device is engineered to require a greater force for disengagement than for initial engagement, enhancing its reliability.

Additionally, the patent outlines several features that enhance the functionality and durability of the cable locking device. Both parts can be made of copper, and a watertight seal can be included to prevent moisture ingress. The design also incorporates set screws for securing the electrical wires within their respective cavities and a threaded sleeve for compressing a bushing against the wire's outer surface. The symmetrical curvature of the convex and concave surfaces, along with the specific dimensions of the pin and channel sidewalls, ensures a robust frictional connection. Overall, the invention aims to provide a secure, efficient, and user-friendly solution for connecting electrical wires in various applications.
