Abstract: A portable charger having a vacuuming function includes a power supply portion, a dust suction portion, and a connecting assembly. The power supply portion supplies power to the dust suction portion or an external device. The dust suction portion sucks dust. The connecting assembly connects the power supply portion to the dust suction portion or separates the power supply portion from the dust suction portion. The connecting assembly includes a driving piece, at least two connecting pieces, and an elastic piece. The elastic piece is fixedly connected to the at least two connecting pieces. The driving piece drives the at least two connecting pieces to move, and synchronously drives the elastic piece to deform to stretch, so that the driving piece, the elastic piece, and the at least two connecting pieces are switched from a first state to a second state.

Abstract: An electrical connector includes a base having a plurality of through holes, and a plurality of conducting pins respectively located in the through holes. There is a convex block located at the side wall of the base for each of the through holes. Each of the conducting pins has an arm portion. The arm portion and the convex block are located at the same side. The arm portion has a through opening, and one end of the arm portion is bent and extended to form a contacting portion. The contacting portion has an opening that links with the through opening to form a channel that makes the convex block pass through the channel without interference. Because of the lack of interference, the conducting pin will not be damaged due to contact with the convex block when the conducting pin is installed into the through hole.
