Circular device for making electrical connections

摘要

Two cables containing electric wires are electrically connected via a connecting device. The device includes a plurality of electrical connection units arranged in parallel and linked via a flexible linking portion. Each of the electrical connection units includes a groove adapted for stacking an electric wire of a first cable and an electric wire of a second cable to be connected thereto. Each groove is mounted with a cutting element. When the electric wires are received in the groove, the cutting element cuts into the electric wires and contacts a wire core included in the electric wire. Adjacent electrical connection units are connected through a flexible linking portion. By virtue of this connecting device, the cables are easily connected on the installation site and generation of an excess length of the cable is avoided.
