Patent ID: 8641438

Claim:
An electronic device comprising: a circuit board that has an electrode-formed surface on which a plurality of electrodes are formed at least on one side of an edge portion of the circuit board; and a card edge connector that provides electric connection with the circuit board, the card edge connector including: a housing defining an insertion opening for receiving the edge portion of the circuit board, the insertion opening having a first end that opens on an end surface of the housing and a second end opposite to the first end, the insertion opening extending in the housing in a first direction, the housing having insertion opening surfaces that are opposed to each other in a second direction perpendicular to the first direction and defines the insertion opening therebetween; a plurality of terminals including housing-fixed portions fixed in the housing and terminal projections extending from the housing-fixed portions and projecting into the insertion opening from at least one of the insertion opening surfaces, which faces the electrode-formed surface of the circuit board, toward the second end of the insertion opening, the terminal projections being arranged in the insertion opening in a third direction perpendicular to the first direction and the second direction, the terminal projections being resiliently deformable and including contacts to be in contact with the electrodes of the circuit board; and a slider disposed in the insertion opening between the contacts of the terminal projections and the second end of the insertion opening with respect to the first direction, wherein each of the terminal projections includes a slider-contact portion between the contact and a tip end of the terminal projection, the slider is movable from an initial position before the circuit board is inserted into the insertion opening from the first end to an insertion completed position where an insertion of the circuit board is completed when the circuit board is inserted into the insertion opening, the slider has a support surface, when the slider is at the initial position, the slider-contact portions of the terminal projections are supported on the support surface of the slider so that the terminal projections are resiliently deformed toward the one of the insertion opening surfaces and the contacts are separated from the electrode-formed surface of the circuit board with respect to the second direction, when the slider is at the insertion completed position, the slider-contact portions are completely separated from the slider, the contacts are in contact with the electrodes, and the terminal projections are in a state of applying a spring back force of resilient deformation to the circuit board through the contacts; the slider has a plurality of grooves corresponding to the slider-contact portions of the terminal projections, and the support surface of the slider is provided by a bottom surface of each of the grooves.
