Patent number: 7621788Abstract: A pin-carrier for a connector has a main panel defining a plane, a secondary panel, a first pin set with multiple first pins and a second pin set with multiple second pins being connected between the main panel and the secondary panel, wherein the first and second pins have connecting segments being raised or lowered relative to the plane. Therefore, manufacturing the pin-carrier requires fewer steps, fewer tools and since the pins are connected to both panels, has higher yields. Therefore, manufacturing the pin-carrier is low cost and convenient.Type: GrantFiled: January 13, 2009Date of Patent: November 24, 2009Assignee: Comtek Electronics Co., Ltd.Inventor: Dong-Chu Feng

Publication number: 20090149070Abstract: An all-in-one card connector has a insulating case, a first base, a second base, a single card terminal assembly and multiple modular card terminal assemblies. The single card terminal assembly is formed on the first base and is inserted into one end of the insulating case. The modular card terminal assemblies are formed on the second base and are inserted into the other end of the insulating case. After inserting, the bases are cut from the single and modular card terminal assemblies. Because multiple modular card terminal assemblies are all formed on the second base, the material for the base is saved to reduce the cost and the mounting process is also simplified.Type: ApplicationFiled: November 7, 2008Publication date: June 11, 2009Applicant: Comtek Electronics Co., Ltd.Inventor: Dong-Chu Feng

Patent number: 7267561Abstract: A card connector includes a base having an opening at a front end thereof, two guide channels at bilateral sides inside, and a plurality of terminals mounted at a rear end thereof; at least one movable member movably mounted in the guide channels and having a stopping portion and a bevel formed at upper and lower sides of a front end thereof; a stopping plate pivotably mounted to the base for pivoting movement between a stopping position and a releasing position. While the stopping plate is located at the stopping position, the movable member engages to lock the stopping plate. While the movable member is close to the guide channel, the movable member releases the lock-up status. At least one resilient member is provided for generating resilience keeping movement of the stopping plate toward the stopping position. Therefore, the card connector allows/blocks the normally/erroneously inserted card.Type: GrantFiled: December 29, 2005Date of Patent: September 11, 2007Assignee: Tai-Sol Electronics Co., Ltd.Inventors: Yaw-Huey Lai, Dong-Chu Feng

Patent number: 7153165Abstract: A terminal-protective card connector includes a shell and a pressing member. The shell includes at least two groups of terminals mounted to the shell. The second group of terminals each have a part elastically rising upward and backward. The pressing member includes a plurality for elongated slots formed therein and a plurality of pressing points each defined under a front end of each elongated slot. The pressing member is provided with two ends pivotally mounted in the shell for pivoting movement. One group of terminals extends through bottom sides and then top sides of the elongated slots respectively, having a part contacting against and supporting the pressing points to enable the pressing member to rise for a predetermined height. Thus, a specific group of terminals can be optionally pressed to avoid deformation or short circuit resulted from impact of or contact with uncorresponding cards to be protected.Type: GrantFiled: August 2, 2005Date of Patent: December 26, 2006Assignee: Tai-Sol Electronics Co., Ltd.Inventors: Yaw-Huey Lai, Dong-Chu Feng

Patent number: 7040928Abstract: A terminal-protective card connector includes a shell and a pressing member. The shell includes at least two (first and second) groups of terminals mounted thereto, and two upright guiding portions formed at two internal sidewalls thereof. The pressing member includes two guided parts formed at two ends thereof and slidably mounted to the two guiding portions, a plurality of through holes formed therein, and at least one bevel formed at a front end thereof. The second group of terminals has contact portions running through bottom sides and then top sides of the through holes respectively to support the terminals of the second group. Thus, a specific group of terminals can be optionally pressed to avoid deformation or short circuit resulted from impact of or contact with uncorresponding cards to be protected.Type: GrantFiled: August 2, 2005Date of Patent: May 9, 2006Assignee: Tai-Sol Electronics Co., Ltd.Inventors: Yaw-Huey Lai, Dong Chu Feng
