Problems solved by technology

[0011] Conventionally, if a card (hereinafter, referred to as a non-target card B) thicker than the target card A is inserted, and the surface of the non-target card B is in contact with the contacts 100, then as Image 6 (a), Image 6 As shown in (b), there is a problem that the elastic contact piece 101 is more deflected than the original deflection amount according to the thickness difference D between the applicable target card A and the non-target card B.
[0012] In addition, such excessive deflection generates excessive stress, thereby plastically deforming the elastic contact piece, which may cause poor contact or the like.
[0013] In particular, with the miniaturization of mobile terminals and cards, such card connectors are also required to be miniaturized, and the influence of plastic deformation caused by such excessive deflection tends to be significantly manifested.

Embodiment Construction

[0034] Next, based on Figure 1 to Figure 5 The illustrated embodiment illustrates an implementation of the card connector of the present invention.

[0035] In this embodiment, a card tray-type card connector is taken as an example for description. The card connector 1 is equipped with: a card capable of selectively accommodating multiple (two types in this embodiment) cards A and B with different specifications. a tray 2; a housing 3 into which a card is inserted using the card tray 2; and various contacts 4, 5 arranged on the housing 3 and corresponding to the respective cards A, B.

[0036] One card A is an IC card such as a micro SIM card, and the other card B is a memory card such as a micro SD card. Compared with the one card A, the other card B is partially or entirely thicker.

[0037] In addition, in this embodiment, on the basis of the contact 4 of the invention of the present application, the card A is called a target card, and the other card B is called a non-tar...

Abstract

The present invention provides a card connector capable of maintaining a stable contact state in accordance with a card having a different thickness and capable of suppressing excessive deflection of the elastic contact piece. The elastic contact piece (43) is provided with a resilient base portion (431) having one end supported on the housing (3), a main elastic piece portion (432) swingably supported on the elastic base portion (431), and a resilient contact piece (433), and the elastic base portion (431) is provided with a base portion (311) disposed at a distance from the support end (431a) supported by the housing (43) ) The abutment portion (6) is detected by the inner non-object card, and the spring constant is large and difficult to flex with the main elastic piece portion (432).

Description

technical field [0001] The present invention relates to a card connector for connecting cards such as IC cards and flash memory cards to electronic devices such as mobile phones and smart phones. Background technique [0002] Conventionally, IC cards and flash memory cards have been used as external storage media for mobile terminals such as mobile phones and smartphones, and card connectors have been used to connect these cards. [0003] This card connector has a housing with a card insertion portion for inserting a card, and a plurality of contacts disposed on the housing and protruding toward the card insertion portion. When a card is inserted into the card insertion portion, it is formed on the card ( Hereinafter, the pad portion on one side of the object card) is in contact with the appropriate contact portion of each contact, so that the object card is electrically connected to the mounting substrate via each contact. [0004] The contact includes, for example, an ela...
