A card connector () comprises a first insulative frame () fixed to a mounting surface (), and a second metal frame () defining an insertion cavity () for a card () between the mounting surface () and the second frame (). The second frame () is of a channel shape, and has first and second side walls (). An inverted card insertion preventing projection () for preventing the card () from being inserted upside down into the insertion cavity () is provided on one of the first and second side walls (). The inverted card insertion preventing projection () projects in an area (A) of the insertion cavity () associated with the first half of a card inserting stroke.

Card connector

Providing an ejector mechanism for card connector which is of a type wherein a transmission pin retained by a drive member is circulated in a heart-shaped cam groove along a predetermined circulating direction in conjunction with reciprocal movement of a push rod. A resilient cantilever arm has its fixed end secured to the drive member. A free end of the cantilever arm defines a bent projection, which is provided with the transmission pin. The cantilever arm utilizes its own resilience for urging the transmission pin against a bottom of the cam groove.

Ejector mechanism for card connector

A contact capable of achieving the reduction of height in the direction of displacement, and of obtaining excellent contact pressure. A contact comprises substantially a belt-like elastic contact member having a terminal at one end and a contact part at the other end and substantially a belt-like elastic protection member having a fixing part at one end and a protecting part at the other end and an accommodation hole provided in the protection member between the fixing part and the protecting part , wherein the elastic contact member is spaced from and disposed in parallel with the protection member at a given interval while a tip end of the contact part of the elastic contact member is positioned inside and in parallel with the protecting part . The accommodation hole is formed such that a part of the elastic contact member enters accommodation hole as the elastic contact member is elastically deformed. When another contact contacts the contact part of the elastic contact member of the contact , the elastic contact member is moved downward-and displaced, and a part of the elastic contact member near the contact part , for example, a flat part , an inclined face and a tip end enter the accommodation hole
