Abstract: A card connector base is mounted on a printed circuit board and has a metal-inserted housing, a pair of hooking assemblies and a card tray. The metal-inserted housing has a metal substrate and an insulative body. The insulative body is mounted securely on the metal substrate by an insert-molding process. The hook assemblies are mounted on the metal-inserted housing. The card tray is detachably mounted slidably in the metal-inserted housing. Because the metal substrate formed from the sheet-metal is thin and has fine structure strength such as tensile strength and compressive strength, the metal-inserted housing with the metal substrate is more compact and more structurally strong when compare to conventional insulative housings.

Abstract: An electrical connector for engaging with an electronic card has a insulative housing with a plurality of receiving spaces, a plurality of terminals respectively mounted in the receiving spaces of the insulative housing, and an operating member pivotally connected to the insulative housing. The operating member controls the terminals in the insulative housing to be moved for electrically and mechanically engagement with the electronic card. Each of the terminals has a base portion, an upper arm and a lower arm. The upper arm is connected to the base portion at a joint as a first fulcrum. The lower arm is connected to the base portion at another joint as a second fulcrum. As the operating member pivotally moves to a predetermined position, the upper arm and the lower arm respectively rotate about the first fulcrum and the second fulcrum to securely grasp the electronic card.
