Patent number: 8262400Abstract: A card connector includes an insulating housing defining a first receiving chamber and a second receiving chamber. A fool-proofing member has a pivot pillar vertically pivoted in one side of the insulating housing, a first fool-proofing portion and a second fool-proofing portion protruded on an outside face of the pivot pillar and apart designed at an upper position and a lower position of the pivot pillar at an angle. An elastic element is put around a top of the pivot pillar to make the first fool-proofing portion hidden in the insulating housing and the second fool-proofing portion stretched in the second receiving chamber for receiving one card in the first receiving chamber. The first fool-proofing portion stretches into the first receiving chamber under the rotation drive of the fool-proofing member realized by another card being inserted into the second receiving chamber to push the second fool-proofing portion rearward.Type: GrantFiled: July 19, 2011Date of Patent: September 11, 2012Assignee: Cheng Uei Precision Industry Co., Ltd.Inventors: Zhi-Cheng Qu, Bing-Tao Yang, Yin-Lung Wu, Ming-Chiang Chen

Patent number: 8246391Abstract: A connector terminal is assembled in an insulating housing defining a receiving cavity of which front and rear sides protrude face-to-face to form two blocking eaves. The connector terminal has a fastening strip of which a bottom edge protrudes downward to form two elastic arms spaced from each other, and a soldering portion between the two elastic arms. The elastic arms are apart from two opposite side edges of the soldering portion to define two receiving intervals between the soldering portion and the elastic arms. Distal ends of the elastic arms oppositely protrude to form two fastening barbs. The soldering portion and the elastic arms are inserted in the receiving cavity. The fastening barbs slide through the blocking eaves to be hooked under the blocking eaves respectively and the fastening barbs can be avoided scraping the connector by means of cushion effects of the receiving intervals.Type: GrantFiled: April 20, 2011Date of Patent: August 21, 2012Assignee: Cheng Uei Precision Industry Co., Ltd.Inventors: Zhi-Cheng Qu, Bing-Tao Yang, Yin-Lung Wu, Ming-Chiang Chen
