Memory card adaptor

Abstract

The present invention relates to a memory card adaptor which enables a small memory card to be used in a card connector for a large memory card that is larger than the small memory card. Even a contact spring piece portion of the different shape can maintain stable contact with a terminal 303a of a micro SD card.

Claims

1. A memory card adaptor comprising: an adaptor body which is configured by a base, and a cover covering said base, and in which a card insertion port into which a small memory card is to be inserted is disposed in a front side face, a card attaching portion which communicates with said card insertion port, and to which a small memory card is to be attached is disposed in an inner front portion, and outer dimensions are identical with outer dimensions of a large memory card that is larger than the small memory card; and an electrical connection part between the small memory card and a card connector for the large memory card, said electrical connection part being a composite part configured by an insulative member and plural conductive members, and formed by insert molding, said insulative member being housed in an inner rear portion of said adaptor body, cantilevered front end portions of said conductive members being protruded from said insulative member into said card attaching portion, and forming contact spring piece portions which are to be elastically contacted with terminals of the small memory card attached to said card attaching portion, rear end portions of said conductive members being exposed from a rear face side of a rear end portion of said adaptor body, and forming contact piece portions with which terminals of the card connector for the large memory card are to be elastically contacted,at least one of said contact spring piece portions being formed into a different shape not by a front end portion of a conductive member protruded from said insulative member into said card attaching portion of said adaptor body in a straight manner in a plan view, but by a front end portion of a conductive member protruded in an L-like shape, whereinsaid memory card adaptor further comprises a resin-made pressing member which interposes a root part of said contact spring piece portion of the different shape between said pressing member and said adaptor body.

2. A memory card adaptor according to claim 1, wherein a plug portion which is fitted into a tool insertion hole is disposed integrally in said the pressing member, said tool insertion hole being formed in said insulative member when insert molding is performed on said insulative member and said plural conductive members in a state where said conductive members are integrally coupled to a hoop material, and being used for, after the insert molding, cutting off unwanted coupling portions of plural conductive members in an integrally coupled state.
