Description

  The present invention relates to a card connector for electrically connecting a PC card and a printed board, and more specifically to a method for mounting the card connector on the printed board.

  In general, portable personal computers tend not to incorporate a selective expansion device in order to pursue portability and reduce weight. When connecting an expansion device to a personal computer, it is connected using a connector capable of accommodating a card-type device generally called a PC card such as SCSII and an electric cable. The electrical connection between the PC card and the printed circuit board in the personal computer is made through a connector that can insert and remove the PC card and has a large number of electrical contact pins. The pins provided in the connector are usually arranged in a line along the width direction of the PC card, and one or more stages thereof are provided and arranged.

  The card connector is required to have various mounting forms on the printed circuit board in accordance with circuit design in manufacturing and market needs. For example, it may be the front and back surfaces of the printed circuit board or the edge of the printed circuit board. However, since most of them have a form in which a PC card is inserted and removed parallel to the surface of the printed circuit board, the mounting of the connector on the printed circuit board is preferably attached on any surface of the printed circuit board. Regardless of whether the card connector is mounted on either side of the printed circuit board, the PC card must be identical on the front and back sides in order to prevent incorrect insertion of the PC card taking into account the pin arrangement (pin polarity). Note that it must be inserted into the connector in a maintained state.

  In addition, even when the card connector is attached to any surface, the card connector is required to have a certain degree of durability against an impact or an external force. Therefore, the card connector usually has a structure in which a reinforcing portion is incorporated in the card connector.

Patent Document 1 discloses a card connector that can be attached to either the upper side or the lower side of a printed circuit board. The card connector uses a pair of mounting brackets, and when the card connector is mounted on either side of the printed circuit board, each connecting portion along the width direction and insertion / removal direction of the PC card can be obtained simply by reversing the mounting bracket. Can be held at the same position.
