Problems solved by technology

[0023] However, in such a card connector, when the contact terminals 105, 106 and the conductive foil of the substrate are soldered by reflow soldering heating, the resin case 100 will soften, so the movable contact terminal 107 will receive a pressing force. The housing 100 where the fixed contact terminal 108 is fixed warps due to the pushing force, causing the fixed contact terminal 108 to fall toward the center side of the housing 100. If the thin wall to which the fixed contact terminal is fixed falls down, the fixed contact terminal 108 and the The contact load of the movable contact terminal 107 is reduced

Embodiment Construction

[0066] Hereinafter, a card connector according to an embodiment of the present invention will be described with reference to the drawings.

[0067] Such as Figure 1 to Figure 5 As shown, the card connector 1 of this embodiment includes a resin housing 10 , a metal shield 20 , and a normally closed switch SW-NC composed of fixed contact terminals 30 and movable contact terminals 40 .

[0068] Such as figure 2 , Image 6 As shown, the housing 10 has: a card support portion 11, an edge portion of the upper surface of the card support portion 11, and a side wall portion 12 extending from the front R side of the card medium insertion direction toward the front F side of the card medium insertion direction, and the card support portion 11. The other edge of the upper surface of the support portion 11 is connected to a side wall portion 13 extending in the same direction as the side wall portion 12, and a spacer is formed between the side wall portions 12,13. Figure 4 , Figur...

Abstract

The invention relates to a card connector. The portion, of the housing, fixed with a fixed contact terminal can be prevented from being warped during the reflow soldering heating process, and the load on the contact of the fixed contact terminal and a movable contact terminal can be prevented from being reduced. The card connector (1) is provided with a housing (10), a shielding case (20), the fixed contact terminal (30) and the movable contact terminal (40). Two marginal parts on the upper surface of a card supporting portion are provided with sidewall portions (12, 13) which extend from one side to the other side, and a card media is inserted between the sidewall portions (12, 13). The shielding case (20) is installed in the housing (10) and covers the card media which is inserted between the sidewall portions (12, 13). The fixed contact terminal (30) is arranged on the sidewall portion (12) in a manner that a fixed contact (31) faces the side of the housing (10). In the movable contact terminal (40), a force is applied to the movable contact (41) towards the fixed contact (31), and the shielding case (20) is provided with a transformation prevention portion (70) which supports the sidewall portion (12) and prevents the sidewall portion (12) from falling down towards the central part of the housing (10).

Description

technical field [0001] The present invention relates to card connectors. Background technique [0002] Conventionally, card connectors used in electronic devices such as mobile phones and information terminals are known to include a switch element for detecting the insertion state of a card into the card connector (for example, refer to Patent Document 1). [0003] Such as Figure 9 As shown, the existing card connector is provided with a contact terminal 105, 106 and a switch element SW in a housing 100 into which unillustrated card media such as SD cards and MMC cards are inserted. 1 . [0004] The casing 100 is formed of a resin material, and has: frame portions 121, 122 extending toward the card medium insertion direction and facing the card medium width direction; The frame part 123 that the end part connects. [0005] The housing 100 has a card medium accommodating portion 124 that is recessed in the thickness direction of the card medium in a range surrounded by th...
