Abstract: A screw lamp cap and a screw lamp socket are provided. The screw lamp cap includes a screw lamp cap socket, an insulating fixed plate, an electrode piece of a hot wire, and an electrode piece of a null wire. The null wire electrode is fixed to the screw lamp cap socket. The hot wire electrode is mounted to the screw lamp cap socket via the insulating fixed plate. The hot wire electrode is provided with a flexible plate. The flexible plate extends through the insulating fixed plate and extends into the screw lamp cap socket. The insulating fixed plate is provided with a barrier bar. The barrier bar is disposed between the null wire electrode and the hot wire electrode. The barrier base is configured to increase a creepage distance.

Abstract: A mounting assembly for an electrical box is provided, which includes a power socket, a bracket and a connecting member. The connecting member is configured to act on the bracket and the electrical box to restrictively mount the bracket on the electrical box. The bracket is provided with a plurality of connecting protrusions at intervals. The socket box is provided with a groove, and the plurality of connecting protrusions are corresponding to the groove. The connecting member is mounted on the groove of the electrical box, and a part of the connecting member in the groove successively penetrates through the plurality of connecting protrusions.

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 steering knuckle, including a rod part, a disc part, an ear part including a first ear and a second ear. The rod part and the ear part are disposed on two sides of the disc part, respectively. The first ear is longer than the second ear. The first ear and the second ear each include a pin hole; the connection line of two pin holes of the first ear and the second ear is perpendicular to the axis of the rod part. The first ear extends parallel to the axis of the rod part in the direction away from the disc part to form a pulling arm configured to connect to a steering drag link. The second ear extends perpendicularly to the axis of the rod part and perpendicularly to the connection line of the two pin holes to form a steering arm configured to connect to a steering tie rod.

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.
