Problems solved by technology

Therefore, when the base member is warped beyond the required predetermined flatness, there is a possibility that one end of the fixed terminal portion cannot be fixed to the conductive layer of the wiring board.
In addition, since the contact portion of each contact terminal does not reliably contact the contact pad of the IC card, the electrical connection between the IC card and the electronic device may become unstable.
[0007] In the above case, as shown in the above-mentioned Japanese Patent Laid-Open No. 2003-331956, the soldering portion of the terminal portion of each contact fixed on the base member is formed from both sides along the longitudinal direction of the base member. When the part protrudes, the base member cannot avoid warping in the width direction perpendicular to its length direction due to insufficient rigidity of the base member.

Embodiment Construction

[0018] figure 1 The appearance of an example of the connector for IC cards of this invention is shown.

[0019] figure 1 The illustrated connector for an IC card electrically connects, for example, an electrode portion of a memory card SC that is an IC card and a connection terminal portion of a wiring substrate. In the card accommodating portion 10A, the above-mentioned wiring board is arranged inside a predetermined electronic device. The IC card connector is disposed inside electronic equipment such as a mobile phone, a telephone, a PDA (Personal Digital Assistant, a handheld computer), and a camera, for example. The thin plate-shaped memory card SC is, for example, a SIM card (Subscriber Identification Card), and six electrode pads are formed on one surface of the memory card SC corresponding to the arrangement of contact terminals described later. In addition, the thin plate-shaped memory card SC is not limited to the above example, and may be another memory card other...

Abstract

The invention provides a connector for an IC card. In an inlaid formed base component (10), a projection part (14d) corresponding with an adjacent another contact terminal (14ai) is inserted into a concave part (14r) in a movable slice supporting part (14D) of one contact terminal (14ai) by a preset clearance (Ga).

Description

technical field [0001] The present invention relates to an IC card connector for electrically connecting a mounted IC card and a wiring board. Background technique [0002] An IC card connector on which an IC card such as a SIM card is mounted is arranged on a wiring board in an electronic device as shown in, for example, Japanese Patent Application Laid-Open No. 2008-097947. In the IC card connector, a group of contact terminals for electrically connecting the IC card and the wiring board is provided in the card accommodating portion. Each contact terminal constituting such a contact terminal group is made of a sheet metal material, and is supported by a resin-made base member on the connector at a fixed terminal portion described later. One end of the fixed terminal portion of each contact terminal protrudes outward from the card insertion opening of the card accommodating portion, or protrudes outward from a rear wall forming the card accommodating portion facing the car...
