Patent ID: 8517775

Claim:
An electrical connector adapted for connecting with a mating part, comprising: an insulating housing having a base portion and an inserting tongue extending forward from a front side of the base portion, an inserting mouth being opened in the inserting tongue and penetrating through a front side of the inserting tongue, the inserting tongue defining a plurality of terminal grooves communicating with the inserting mouth and each further extending longitudinally to penetrate through the base portion; a plurality of electrical terminals assembled in the terminal grooves of the insulating housing respectively, each electrical terminal having a connecting arm, a contact arm and a soldering tail connected with two opposite ends of the connecting arm, the contact arm elastically stretching into the inserting mouth and defining a contact end, the soldering tail projecting behind the base portion; and a pair of locking parts and a pair of holding parts, the locking parts are inserted forward in two opposite sides of the insulating housing and have a pair of locking blocks oppositely protruding sideward out of two opposite side faces of the inserting tongue for securing the mating part and the electrical connector together, the holding parts are mounted to two ends of a rear of the base portion and located behind the corresponding locking parts to restrain the locking parts in the insulating housing, wherein the inserting tongue further defines a plurality of through holes penetrating vertically through the inserting tongue to connect with the inserting mouth and arranged in accordance with the contact ends of the electrical terminals, the through holes are used to provide action space for meeting movements of the contact ends and receiving the contact ends therein, when the mating part is inserted into the inserting mouth of the electrical connector and pressure contacts with the contact ends.
