Card connector
A card connector for receiving an inserted card module having electrode pads on one surface is provided. The card connector includes a housing and a plurality of terminals. The housing has a terminal holding portion. Each terminal has a base portion held in the terminal holding portion and a cantilevered arm portion extending from the base portion in a transverse direction relative to an insertion direction of the card module in plan view. The arm portion has a curved portion shaped so as to have a curved surface with a centerline of curvature positioned upwards in side view and a pair of oblique portions inclined relative to an extension direction of the arm portion on both sides of an apex portion positioned on a free end. The terminals contact the electrode pads of the card module.
1. A card connector for receiving an inserted card module having electrode pads on one surface, the card connector comprising:
a housing, the housing having a terminal holding portion; and
a plurality of terminals, each terminal having a base portion held in the terminal holding portion and a cantilevered arm portion extending from the base portion in a transverse direction relative to an insertion direction of the card module in plan view, the arm portion having a curved portion shaped so as to have a curved surface with a centerline of curvature positioned upwards in side view and a pair of oblique portions inclined relative to an extension direction of the arm portion on both sides of an apex portion positioned on a free end, the terminals contacting the electrode pads of the card module.
2. A card connector according to claim 1 , wherein the arm portion includes a flat panel portion connected to the base portion and extending parallel to an upper surface of the terminal holding portion, the apex portion connected to a leading end of the curved portion, and a forward portion positioned above the upper surface of the terminal holding portion.
3. A card connector according to claim 2 , wherein the shape of the arm portion in side view does not include an inflection point and a portion of the arm portion connected to the base portion is connected linearly to the base portion.
4. A card connector according to claim 3 , wherein the oblique portions include a section positioned above the upper surface of the terminal holding portion.
5. A card connector according to claim 3 , wherein the arm portion includes an opening passing through the arm portion in a thickness direction, and the opening has a diamond shape with one axis extending in the extension direction of the arm portion in plan view.
6. A card connector according to claim 5 , wherein a width dimension of the section of the arm portion excluding the opening gradually increases linearly towards the base portion from the free end of the arm portion.
7. A card connector according to claim 1 , wherein the terminals are arranged in rows extending in the insertion direction of the card module, and the position of the apex portion of each terminal in the rows is different relative to the transverse direction in the insertion direction of the card module.
