Abstract: An electrical connection assembly includes a first electrical member and a locking structure configured to lock the first electrical member to a second electrical member cooperating with the first electrical member. An adjusting sleeve is sheathed on an outer surface of the first electrical member and movable along an axis of the first electrical member. A collar is sheathed on an outer surface of the adjusting sleeve. A connecting bracket is rotatably connected to the collar. The second electrical member includes a first end coupled to the first electrical member and a second end opposite to the first end. The connecting bracket is rotatable to the second end of the second electrical member for limiting the second end of the second electrical member.

Abstract: A wire connecting device for connecting and electrically communicating a first electrical wire and a second electrical wire can include: an electrical connector having a first end, a second end, and a concave portion between the first end and the second end, wherein the concave portion is configured for accommodating a second core wire of the second electrical wire; and a connecting member cooperating with the electrical connector and configured for guiding the first end and the second end of the electrical connector connected with the first electrical wire. A wire connection method using the wire connecting device can be further provided.
