  • Patent number: 9653827
    Abstract: A battery connector includes an insulating body, a plurality of electrical terminals and a plurality of conducting pieces. The insulating body defines a plurality of terminal grooves penetrating through a front and a rear thereof and a plurality of inserting grooves communicating with the respective terminal grooves. The electrical terminals are assembled into the terminal grooves of the insulting body. The conducting pieces are assembled into the inserting grooves of the insulating body and contact with the electrical terminals. When the battery connector electrically connects the battery and the circuit board, part of the current passes through the conducting pieces, therefore heat generated by the electrical terminals is reduced to ensure that the temperature of the battery connector is within the normal range.

  • Patent number: 9640917
    Abstract: An electrical connector includes an insulating housing, a plurality of terminals located in the insulating housing, a main shielding shell and an auxiliary shell. The insulating housing has a main body, and a tongue portion protruded frontward from a front surface of the main body. The main shielding shell surrounds the main body and the tongue portion of the insulating housing. The main shielding shell has a main plate, a bottom plate and two lateral plates. A middle of the bottom plate defines an avoiding gap. The auxiliary shell has a base plate, and two flanks extended outward from two opposite sides of the base plate. The two flanks are fastened to bottom surfaces of two side walls of the avoiding gap and the base plate is located under the avoiding gap.
