Connector for cards

Abstract

This invention provides a connector device for a card allowing the improvement of contact reliability of a contact part of a detection switch detecting insertion / installation of the card, and allowing miniaturization of the connector device. This connector device has: a lock member 7 holding a slide member 10 movable according to the insertion and discharge of a card in a card insertion / installation position; and a detection means detecting the insertion / installation of the card. The detection means has: first and second fixed contacts 5a, 5b provided in a housing 1; and a movable contact 9 connecting the first and second fixed contacts 5a, 5b. The movable contact 9 is formed of one twist coil spring having two end turn parts, the twist coil spring is formed with a first contact spring 9a abutting on the first fixed contact 5a and a second contact spring 9b abutting on the second fixed contact 5b, and the first contact spring 9a and the second contact spring 9b are respectively extended from the different end turn parts.

Description

technical field [0001] The present invention relates to the structure of a card connector device used for small memory cards and the like used in various portable information terminals such as mobile phones and PCs, digital cameras, digital AV equipment and other memory-applied devices. Background technique [0002] As an additional storage device for electronic equipment such as a personal computer or a digital camera, a card connector device is generally used. As a storage medium of this card connector device, a PC card, a memory card, etc. are widely used. As this conventional card connector device, there is known one in which a housing portion for inserting a card is formed inside a casing such as a casing, and a plurality of connector terminals (contacts) are arranged in parallel on the housing portion, so that the connector A device in which contacts of a terminal are connected to external contacts of a memory card or the like inserted in an accommodating portion to w...

Problems solved by technology

[0011] However, in the structure of the conventional card connector device, the contact (connector terminal) 52 held on the insulator (housing) 51 is inserted into the card 20 by forming the free end side of the contact 52a. direction from the inside to the front (card insertion slot direction), so there is a problem that, for some reason, the contact 52a is mounted to the lower side of the card housing portion, When the card 20 is inserted, the front end of the card 20 will collide with the front end of the contact 52a, which will cause the contact 52 to buckle or deform, resulting in poor contact.

[0012] In addition, in order to prevent the front end of the contact 52a from colliding with the front end of the card 20, and to bend it upward and protrude in advance, it is necessary to set the height of the insulator high so as not to touch the contact when the card 20 is inserted. The point 52a protrudes from the insulator (housing) 51, so there is another problem of increasing the size of the connector device

[0013] In addition, as long as the contact (connector terminal) 52 held on the insulator (housing) 51 is formed in such a manner that the free end side forming the contact 52a extends inward with respect to the insertion direction of the card 20, But in this case, just become the form that the holding part of contact 52 is oppositely positioned at the insertion port side of card accommodating part, so when card is inserted, when contact 52a of contact 52 contacts with card, as insulator The card insertion port side on the free end side of 51 will be bent toward the card receiving part side due to the elastic pressure of the contact 52, and the contact pressure with the card cannot be ensured.

[0014] In addition, in the structure of the conventional card connector device, the contact portion of the detection switch that detects the insertion state of the card is formed by a contact spring that rotates around the pivot point, and the contact spring is obtained by the same contact spring. The self-restoration of the point spring uses the elastic pressure and the contact pressure of the contact part. Therefore, after a long period of use, there will be problems such as the contact spring slack and falling down, the contact pressure drops, and the contact is unstable.

In addition, in order to increase the contact pressure, the contact spring must be enlarged, so the housing must be enlarged, so there is a problem that it is difficult to realize the miniaturization of the connector device.
