The present invention provides an electrical connection device, which includes a position holding bar, a switching device sleeved outside of the position holding bar, and a wire twining device with position limiting button. The wire twining device comprises an active turnplate, an electrical connection wire enlaced on one surface of the turnplate, an activation point fixed on the other surface of the turnplate, and a reset spring fixed on the annular groove of the bottom of the turnplate; the outer end of the enlaced wire is electrically connected with an active wire port, the inner end of the enlaced wire is connected with the active touching point of the turnplate; a fixed touch point that corresponding to the active touching point is set on the connection device, so that the active touching point keeps the electrical connection with the fixed touching point of the connecting device while the electrical connection wire is twined with the turnplate. When implementing the electrical connection device, it is very convenience to control and use the wire, and makes the wire extending and retracting easily, thus reduces the mass caused by wires and saves the space.
