Description

  The present invention relates to a card connector for connecting a card such as an IC card or a flash memory card to an electronic device such as a mobile phone device or a digital camera, and more particularly to a card connector that can support standoff.

  Conventionally, in this type of card connector, the housing into which the card is inserted is placed in a position that is floated by a certain height with respect to the mounting substrate surface, so that an IC chip and other semiconductor components can be mounted under the housing. The thing of the structure corresponding to what is called standoff is known (for example, refer to patent documents 1).

  The card connector has a housing having a card insertion portion into which a card-like body such as a card tray is inserted, and an elastic contact piece that protrudes into the card insertion portion and contacts a signal transmission terminal exposed on one side of the card-like body. A plurality of contacts are provided, and the card and the mounting substrate are electrically connected through the contacts.

  This contact includes an extension part that is shaped to extend a certain length from the housing toward the mounting board side, and a board connection piece that is bent in the horizontal direction from the lower end of the extension part. The piece is soldered to a signal pattern formed on the mounting substrate.

  However, in the conventional technology as described above, the standoff distance depends on the length of the contact extension, so that the proper thickness of the semiconductor component mounted under the housing is naturally limited, and a plurality of types having different thicknesses are used. The semiconductor component has a problem that it is difficult to deal with.

  That is, in the conventional card connector as described above, when the thickness of the semiconductor component is thin relative to the standoff distance, a wasteful space is generated between the semiconductor component and the housing, and the semiconductor is thicker than the standoff distance. Since parts cannot be mounted under the housing, the degree of freedom of design is limited.

  On the other hand, by adjusting the contact extension mold or its length by adjusting the contact extension length, it is possible to cope with multiple types of semiconductor components with different thicknesses as described above. However, it is difficult to manage the coplanarity, that is, the uniformity of the connection state of each contact connecting terminal piece with respect to the mounting board. There was a problem that there was.

  Furthermore, when the card connector has a conductive component (for example, a shield cover or a timing switch) that is soldered to the mounting board other than the contact, other conductive components such as the shield cover are changed along with the change in the length of the contact extension. The length of the stand-off-corresponding portion needs to be changed, and a plurality of molding dies or pieces for the part must be prepared, which further increases the cost.

  Also, in the card connector corresponding to this type of standoff, the longer the standoff distance, that is, the longer the contact extension, the more the board connection piece due to the force and moment (card tilt) acting on the housing with the card insertion / extraction operation. Since the burden on the soldering portion with the signal connection pattern, that is, the moment acting on the soldering portion also increases, there is a concern about solder peeling due to the moment.

  In view of such a conventional problem, the present invention has been made for the purpose of providing a card connector that can cope with a desired standoff distance and is inexpensive.
