Problems solved by technology

And, because it is the structure that the opposite contact point 92 elastically displaces with respect to the thickness direction of the card, it is difficult to miniaturize especially the thickness direction of the card.

Embodiment Construction

[0029] Next, for the card connector 1 of an embodiment of the present invention, use Figure 1 to Figure 5 Be explained. In addition, for convenience of explanation, the surface where the card 4 is inserted is described as the front surface of the card connector 1 .

[0030] refer to figure 1 with figure 2 , the main structure of the card connector 1 will be described. The card connector 1 has a housing 11 formed by injection molding an insulating resin on the lower side, and a shield case 12 formed by press-molding a conductive thin metal plate on the upper side. The shield cover 12 has three vertical surfaces 12a formed by bending the upper surface of the card connector 1 along the outer shape of the housing 11 to the left and right sides and the back of the card connector 1 perpendicularly. It has a clamping portion 12b formed by bending a part of the front end portion of the vertical surface 12a further vertically toward the inner side of the card connector 1 . The ...

Abstract

The invention provides a card connector provided with a card detecting switch. The card connector provided with the card detecting switch can prevent a condition that foreign matter adheres on a joint part of the switch used for detecting an inserted card, thereby improving the contact reliability with low cost. In the card connector, a joint between a first detecting contact (2) and a second detecting contact (3) of the card detecting switch (16) is arranged outside the card accommodating part (13), thereby avoiding the adherence of the foreign matter. Besides, through arranging the two joints between the first detecting contact and the second detecting contact and friction contact is realized through the slide along with the inserting and plugging of the card in each joint, thereby obtaining high contact reliability. Besides, through arranging the first detecting contact (2) and the second detecting contact (3) in the shapes that do not need to twist and process, the processing cost is controlled.

Description

technical field [0001] The present invention relates to a card connector for mounting various card-type storage media (hereinafter referred to as cards) such as IC cards, SD cards, and SIM cards. device. Background technique [0002] As a conventional card connector having a card detection switch, the card connector disclosed in Patent Document 1 will be described as an example. Such as Image 6 and Figure 7 As shown, the card connector has a card detection switch mechanism composed of a leaf spring-shaped movable contact 91 and a leaf spring-shaped counterpart contact 92. When a card is installed, the sliding contact portion 91f and the first counterpart contact portion 92f , The mating contact portion 91g is in contact with the second counterpart contact portion 92g respectively, so that the movable contact 91 and the counterpart contact 92 are short-circuited, and the installation of the card can be detected. In addition, as the card is inserted, the card detection sw...
