Card connector

Abstract

The invention provides a card connector. The card connector comprises an insulating body, a plurality of conductive terminals and a pair of switch terminals, wherein the conductive terminals and the switch terminals are installed in the insulating body; a first housing groove for housing a butting electronic card is arranged in the insulating body; each switch terminal comprises a first switch terminal and a second switch terminal adjacent to the first switch terminal; the first switch terminal comprises a first contact part; the second switch terminal comprises a second contact part which is adjacent to the first contact part and protrudes and stretches into the first housing groove; and the second contact part is provided with dust scraping blocks which protrude and stretch toward the first contact part and carry out frictional contact with the first contact part in the butting electronic card insertion process so as to remove the insulating foreign matters on the first contact part.

Description

technical field [0001] The invention relates to a card connector, in particular to a card connector provided with dust scraping blocks on switch terminals. Background technique [0002] A conventional card connector for receiving an electronic card usually includes an insulating body, a plurality of conductive terminals fixed on the insulating body, a pair of switch terminals, and a shielding case covering the insulating body. The insulating body and the shielding case form a storage space for accommodating the electronic card; the conductive terminal includes a contact portion extending into the receiving space at one end to cooperate with the electronic card and a welding portion extending out of the insulating body at the other end; The switch terminal includes a fixed terminal and a movable terminal matched with the fixed terminal. The fixed terminal and the movable terminal are arranged on one side of the insulating body on the left and right. When the electronic card i...

Problems solved by technology

[0003] In order to make the electrical connection between the movable terminal and the fixed terminal better, the existing card connector usually has a convex structure on the contact area of ​​the movable terminal, but when the card connector is used for a long time, the convex structure Insulating foreign matter will adhere to the place, which will lead to poor contact of the switch terminal, which will lead to the phenomenon that the electronic card cannot be read.
