Patent number: 7637787Abstract: An audio jack connector has an insulative housing and a plurality of conductive terminals mounted in the housing. The housing includes a body, a mating head and an insertion hole, wherein the body has a rear wall, two opposite sidewalls, a top wall and a bottom wall. A plurality of terminal slots and notches is only defined through the bottom wall, keeping other walls of the housing from forming any opening against the entry of the moisture and dust. The mating head is mounted on the body opposite to the rear wall. The insertion hole is defined through the mating head, extends into the body and communicates each terminal slot. Each notch is parallel to one another and communicates a corresponding terminal slot. Each conductive terminal has a base portion, a mounting portion, a connection portion, a contacting portion and a resilient portion.Type: GrantFiled: November 25, 2008Date of Patent: December 29, 2009Assignee: Advanced Connectek Inc.Inventors: Min-Lung Chien, Kai-Ray Cheng, Hong-Wei Zheng, Ya-Ping Liang
