Abstract: A connector is fixable to an object such as a printed circuit board. The connector comprises a shell having a body portion and two fixed portions for fixing the body portion to the object. The body portion has two side portions and an upper portion coupling the side portions with each other in a lateral direction. The side portions are connected to the respective fixed portions. The fixed portion has a base portion and a strengthener. The base portion is located outward of the side portion in the lateral direction. The strengthener extends inward in the lateral direction from the base portion beyond the side portion.

Abstract: A connector is able to accommodate an object (for example, a tray on which a card is mounted). The connector comprises an ejection member and a backup portion. The ejection member includes a receiver and an ejecting portion. The receiver is able to be pressed by an operating member (for example, a pin). The ejection member pivots from an accommodating position to an eject position when the receiver is pressed. The ejecting portion ejects the object when the ejection member pivots toward the eject position. When the receiver receives an excessive force from the operating member, the backup portion is brought into abutment with the receiver so as to backup the receiver.
