Abstract

A card connector is disclosed that includes an insulating housing and a plurality of contacts. The insulating housing defines a plurality of contact slots. Each of the contact slots extends outwardly and laterally to opposite sides to form two resisting protrusions respectively, wherein each of the resisting protrusions forms a resisting surface extending obliquely and inwardly from one side thereof. The contacts are respectively received in the contact slots of the insulating housing. Each of the contacts has a contact portion protruding upwardly for being pressed by a card and the contact portion is connected with a bearing portion resisting against the resisting surface for preventing the contact portion from flipping upwardly out of the insulating housing.

Claims

1. A card connector, comprising:

an insulating housing defining a plurality of contact slots, each of the contact slots extending outwardly and laterally to opposite sides to form two resisting protrusions respectively, each of the resisting protrusions defining a receiving cavity in a bottom portion thereof; and

a plurality of contacts respectively received in the contact slots of the insulating housing, each of the contacts having a contact portion protruding upwardly for being pressed by a card, the contact portion being connected with a bearing portion received in the receiving cavity for preventing the contact portion from flipping upwardly out of the insulating housing.

2. The card connector as claimed in claim 1, wherein the receiving cavity is of substantially an inverted V-shape and has a first resisting surface and a second resisting surface, the bearing portion received in the receiving cavity has a resisting portion extending downward and inward and a flank portion extending outward and downward opposite the resisting portion, the resisting portion resists against the first resisting surface and the flank portion resists against the second resisting surface.

3. The card connector as claimed in claim 1, wherein each of the corresponding two resisting protrusions and the contact slot cooperatively define a gap, where the bearing portion can move, the gap passes through a corresponding end portion of the insulating housing, the resisting protrusions are located above the corresponding gaps.

4. The card connector as claimed in claim 3, wherein the receiving cavity communicates with the corresponding gap.
