A card edge connector includes an elongated insulative housing, a number of terminals retained to the housing, and a metallic member formed integrally with the housing via an insert-molding process. The housing includes two lengthwise walls, a central slot defining by the two lengthwise walls, and two protrusions located at two opposite ends of the two lengthwise walls. The protrusions protrude upwardly out of an upper surface of the lengthwise walls. The metallic member includes two main portions retained respectively in the two lengthwise walls and a pair of connecting portions connecting therebetween. The connecting portions are located at the bottom of the metallic member.

A connector includes a housing that has a fitting chamber with an insertion opening for a flat conductor in the upper surface thereof and whose lower side is placed on a circuit board, a locking spring that locks the flat conductor, and an unlocking member. The locking spring is provided with a housing fixing portion, an elastic arm that is rotationally displaced about the housing fixing portion away from the flat conductor, an engaging piece that engages with a locking portion of a through-shape provided in the flat conductor, and a sliding contact portion that comes into oblique sliding contact with the unlocking member displaced by a pressing operation, rotates the elastic arm, and extracts the engaging piece from the locking portion.

A memory socket includes a frame having a base portion and a side portion, and a push-eject locking mechanism in physical communication with the base portion and with the side portion. The push-eject locking mechanism to transition between an unlocked position and a locked position. The push-eject locking mechanism includes an eject bar component and a lever component. The weight of the eject bar component biases the push-eject locking mechanism towards the unlocked position. Based on a force being exerted on the lever component, the lever component pivots and transition the push-eject locking mechanism from the unlocked position to the locked position.

A card edge connector with latches that improve the connector's reliability. The connector comprises a housing having a slot for receiving a card and latches on opposite ends of the slot for locking the card in the slot. Each latch includes a body and a projection extending in a transverse direction from a side surface of the body. The latch is pivotably connected to the housing by the projection. The latch may rotate about the projection between a locked position and an unlocked position. The body includes a lower body and an upper body wider than the lower body in the transverse direction. The projection is disposed on the lower body. The latch further includes a protrusion extending between the projection and the upper body. Such a configuration restricts the latches from moving in the housing and therefore improves the reliability of the connector.

An electronic card retaining device includes a seat mounted on a motherboard and having stopper sections; and a movable retaining member pivotally connected to the seat and having a retaining end facing toward a position to where an electronic card is to be fixed, and an operating end provided with guide sections, which can pass the stopper sections to move between a retaining and a releasing position when the movable retaining member rotates pivotally. The electronic card has an end electrically connected to the motherboard and another end for engaging with the retaining end of the movable retaining member. To retain the electronic card, simply push the engaging end thereof downward and the guide sections will move to the retaining position. To release the electronic card, simply sidewardly deform the elastic arm for the guide sections to move from the retaining position to the releasing position.

Provided is an electrical connector to which a flat conductor is connected includes: a housing; terminals; and a movable member, the movable member is movable between a closed position and an open position while rotating, each terminal has an arm part, the movable member maintains a connection state between the electrical connector and the flat conductor when being located in the closed position and allows removal of the flat conductor when being located in the open position, and has a groove that houses a rear end portion of the arm part, when the movable member is located in a predetermined position different from the closed position, the rear end portion is housed in a wide portion of the groove, and when the movable member is located in the closed position, the rear end portion is housed in the wide portion and a narrow portion of the groove.

Provided is an electrical connector to which a flat conductor is connected includes: a housing; terminals; and a movable member, the housing has a receiving portion that receives the flat conductor, a main body of the movable member has a side reinforcement portion that includes an inclined portion that extends inward, a side part of the housing has a shaft restriction portion that is located outside of the side reinforcement portion and restricts movement of a shaft part of the movable member, the side reinforcement portion and the shaft restriction portion are provided adjacent to each other within a predetermined range, and at least a part of the shaft restriction portion is provided in a range that overlaps with the inclined portion, and an inner surface of at least the part of the shaft restriction portion extends at an angle along an outer surface of the inclined portion.
