Patent number: 8568172Abstract: An electrical connector includes a first insulating housing having a base board and a tongue board extending forwards from a front of the base board. Two opposite sides of the base board extend downward to form a pair of clamping boards spaced from each other. A second insulating housing is assembled to the first insulating housing. The second insulating housing has a base portion resisting against rear edges of the clamping boards. A tongue portion protrudes forwards from a front of the base portion to be clamped between the clamping boards. A terminal group includes a plurality of flat terminals and a plurality of spring terminals. The flat terminals are molded in the first insulating housing and the spring terminals are molded in the second insulating housing. A metal shell encloses both the first insulating housing and the second insulating housing.Type: GrantFiled: April 12, 2012Date of Patent: October 29, 2013Assignee: Cheng Uei Precision Industry Co., Ltd.Inventors: Rong-Qin Lan, Li-Jun Xu, Ming-Han Lin
