Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a card edge connector for inserting and connecting a card incorporating an electronic circuit and having terminals lined up at one end thereof.

Specifically, we have developed an improved card design that allows cards of different thicknesses to be connected using the same connector.
edge connector.

[Conventional technology] With the advancement of semiconductor technology, so-called IC cards containing LSIs are increasingly being used, but there are many types of IC cards depending on their purpose and function, and the thickness of the IC card also varies. Something exists.

In order to connect electronic cards with built-in electronic circuits, including these IC cards, to electronic equipment, an extraction electrode was provided on one edge of the electronic card, and this was inserted into a card edge connector.
The width of the slot into which the electronic card is inserted in this card edge connector was manufactured to match the thickness of the electronic card.

[Problem that the invention aims to solve] However, for example, as electronic cards have come to be equipped with RAM (random access memory) and ROM (read only memory), it has become possible to store large amounts of memory using the same card edge connector. There has been a demand for cards with larger capacity, but when the thickness of the card is increased to increase the storage capacity, the problem arises that it cannot be inserted into the same card edge connector.

[Means for solving the problem] The present invention was devised to solve the above problem, and the remaining thickness of the edge of the thick electronic card is placed on the back side of the side where the extraction electrode is located. In order to make it possible to insert such an electronic card, the card edge has at least one cut groove that is the thickness of the thinnest electronic card.
A convex portion was provided on the surface of the card insertion groove of the connector facing the notch of the electronic card so as to fit into the notch.

[Function] The thinnest electronic card is inserted between the top of this protrusion and the surface where the contacts are arranged, and the thicker electronic card is inserted so that the notch of the electronic card fits into the protrusion of the card edge connector. Therefore, the same connector can accommodate the insertion of electronic cards of different thicknesses.

[Example] An embodiment of the present invention is shown in FIG. 1 and will be described.

10 is a connector main body, 11 is a card insertion groove into which an electronic card is inserted, 12 is a contact for contacting the extraction electrode of the electronic card, 13 is a contact groove for the contact 12, and 15 is a cut groove of the electronic card. It is a convex part to fit into.

20 is card A, which is a thick electronic card;
It has a cut groove 25.

30 is card B, which is a thin electronic card;
Its thickness is equal to the thickness of the kerf 25 portion of the card A20.

With this configuration, when the card B is inserted into the card insertion groove 11, the top of the convex portion 15 comes into contact with one side of the card B, so that the card A is inserted into the card insertion groove 11.
The contact between the contact 12 and the extraction electrode 20 (not shown) is maintained completely. Also card A
When the connector 20 is inserted, the protrusion 15 provided on the main body 10 of the connector fits into the cut groove 25, so that the connector 20 is completely inserted.

In the above explanation, the card edge connector for processing cards of two thicknesses, card A20 and card B30, was illustrated.
5, and the thickness of the remaining part of the card A20 at the deepest cut groove 25 is the thickness of the card B30, and this electronic card A2
Convex portion 1 in connector body 10 into which 0 is inserted
The groove width of the card insertion groove 11 at the top of 5 can also be provided with a convex portion 15 having a plurality of different heights so that a plurality of types can be obtained in accordance with the depth of the cut groove 25. It will be clear from the above explanation.

[Effects of the invention] As is clear from the above explanation, the present invention allows electronic cards of different thicknesses to be processed using the same card edge connector, so the functionality of electronic equipment using this invention is greatly improved. It is expanded and extremely convenient to use, and the effects of the present invention are extremely large.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A card insertion groove for inserting electronic cards having various thicknesses, and one side of the card insertion groove is provided on one side of the edge of the electronic card. In a card edge connector in which a contact for making contact with an extraction electrode is arranged, the electronic card is thick and the thickness of the remaining part is on the back side of the surface where the extraction electrode is provided in the insertion part. In the case where there is at least one cut groove that has the thickness of the thinnest electronic card among electronic cards having various thicknesses, a protrusion that fits into the cut groove is provided on the other surface of the card insertion groove. A card edge connector, characterized in that the width of the card insertion groove corresponds to the thickness of the remaining portion of the convex portion. (2) When the electronic card has a plurality of groove depths, the protrusion is made up of a plurality of protrusions whose tops have different heights corresponding to the depths of the grooves.
