Publication number: 20080009150Abstract: The chip connection device's main feature is a structurally simple and rigid engagement member. The engagement member mainly contains a knob having only a top cylinder for turning and indication, an eccentric base cylinder to cause reliable relative lateral movement of the top and base plates of the chip connection device, and a flange between the top and base cylinders. The flange is sandwiched between a top board and a base board of the engagement member and the engagement member is in turn housed between the extensions from the top and base plates of the chip connection device. A clamping member is further provided to clamp the extensions from the top and base plates vertically together and, therefore, the plates can only be engaged into relative lateral movement.Type: ApplicationFiled: June 28, 2007Publication date: January 10, 2008Inventor: KUANG-CHIH LAI

Patent number: 7247043Abstract: A land grid array integrated circuit (LGA IC) connector uses a pressing rod assembly linked with a cover for opening/closing operation. The LGA IC connector includes a first tooth and a second tooth driven by a first post and a second post of a positioning section to enhance the rotation angle thereof. A sufficient pressure can be provided with smaller operation angle of the pressing rod and cover, thus facilitating operation. A protection board is assembled to the terminal stage and then arranged on a frame. A V-shaped spring element is provided between the protection board and the terminal stage such that the protection board is higher than the terminal to protect the terminal. The terminal can be protected from deformation. In the present invention, the terminal is received in the terminal hole and the annular cone at terminal tail can clamp the solder ball.Type: GrantFiled: November 14, 2005Date of Patent: July 24, 2007Inventor: Kuang-Chih Lai

Patent number: 5466169Abstract: An improved zero insertion force socket suitable for engaging with terminals of an integrated circuit such as a CPU of a personal computer. The terminals are permitted to be inserted into and withdrawn from the socket with very little or even zero insertion and withdrawal force. The socket includes multiple contacts and multiple insertion holes each of which has a relatively wide first insertion space for receiving the contacts and a relatively narrow second insertion space for receiving the terminals. Two locating walls are formed at an adjoining portion between the first and second insertion spaces and the each contact has an elastic engaging portion formed with two stopping portions, whereby when the contact is inserted into the first insertion space, the two stopping portion abut against the two locating walls to bias and pre-load the elastic engaging portion of the contact and accurately locate the same at its true position.Type: GrantFiled: August 3, 1994Date of Patent: November 14, 1995Inventor: Kuang-Chih Lai
