The present invention mainly relates to an IC card connector for attaching an IC card to a mobile phone as a removable material.

When using an internationally available mobile phone in a country other than your own country, purchase an IC card for your country. In the form of the IC card, a European standard SIM card is generally used. However, since the stored software programs and data are unique to the country, the IC card must be replaced with an IC card dedicated to that country.

In the cellular phone, the insertion / ejection of the IC card is performed by opening the back cover of the cellular phone and removing the battery if necessary. However, a slide type is generally used as the method of inserting / removing the IC card. 2001-326028, Japanese Patent Laid-Open No. 2003-173844, and the like.

An IC card is inserted into or ejected from an insertion hole of a connector by grasping one end with a thumb and forefinger. Since the IC card is extremely small in length x width x thickness = 25 mm x 15 mm x 0.5 mm, it is necessary to protrude from the insertion opening of the connector as much as the grip part of the IC card.

As a method of reducing the protrusion, there is a push-in / push-out method (Japanese Patent Laid-Open No. 2003-317860). The push-in / push-out method uses a heart-shaped cam and moves one side of the heart-shaped cam with the first push to engage the lock groove, and moves the other side out of the lock groove with the next push. To return to the original. With this configuration, the grip portion is not required, and only the distance of the heart cam is moved back and forth (round trip).

Problems to be solved are as follows.

In the case of a slide type, there is an unnecessary space for lighting that requires a space enough for the finger to be held in order to be gripped by the thumb and forefinger, as long as the grip of the IC card needs to protrude from the insertion hole of the connector.

In addition, the grip of the IC card protruding from the insertion hole of the connector may be deformed or malfunction due to different external force.

On the other hand, the push-in / push-out method eliminates the drawback of the slide type because the protrusion may be small, but the heart-shaped cam mechanism for push-in / push-out is complicated and expensive, and the appearance is also increased. .

It is an object of the present invention to provide a connector having a simple structure and a low cost, in which the projection from the connector insertion port of the IC card is as small as possible when the IC card is inserted or removed.

In the present invention, the IC card 12 is not directly inserted into or inserted into the insertion hole of the connector housing 14, but the IC card 12 is placed on the tray 33 to be withdrawn. By using the tray portion 33, the takeout knob portion 42 is formed in the front edge portion of the tray portion 33 corresponding to the cutout surface 32 of the IC card 12. A nail or the like is applied to the drawer handle 42 to pull out the IC card 12 together with the tray 33. The opening / closing lid 36 at the tip of the tray 33 is made of a hinge material by the hinge portion 39, the tray 33 is pulled out, and the opening / closing lid 36 is interrupted to cut off the IC card 12. Only the IC card 12 can be pulled out by exposing the end of.

The lid 36 approaches the protruding hole 22 side, and the tray 33 is integrally inserted with the IC card 12.

A special structure is added to the IC card 12 by adding a structure that gives a click feeling at the time of insertion, and a structure in which the tray 33 stops in the middle when the IC card 12 is removed. There is no need to have.

In the present invention, in order to insert the IC card into the connector housing and to connect the electrodes of the IC card to the contacts in the connector housing, the connector housing is provided with a slider that can be inserted and removed together with the IC card.

The slider is composed of a tray for placing the IC card, an opening and closing lid provided to be interrupted through a hinge portion in front of the tray, and a protruding jaw for preventing the IC card from being provided at the edge of the opening and closing lid.

In addition, the slider may form an opening / closing lid so as to be able to be interrupted through a thin portion for bending in the front of the tray part without using a hinge for the interruption.

The IC card can be put in and taken out even if the slider is not interrupted and a drawout notch is provided in front of the tray.

In order to be able to insert / extract as much as possible to protrude as necessary, the draw-out handle part is formed in the position of the front edge part of the tray part corresponding to the cutout surface which an IC card has.

Regardless of the shape of the IC card, in order to provide a feeling of click and a function as a stopper, the slider has a click-uneven portion formed in the middle of the lower surface of the narrow arm which extends inwardly from both sides of the tray portion for placing the IC card and the lower surface of the arm.
