[0002] A card connector is an electrical connector installed on portable electronic devices such as mobile phones, which can realize signal transmission between an electronic card and a portable electronic device such as a mobile phone. The card connector specifically includes a card seat and a card tray.

[0003] Chinese Patent CN103367951B discloses a digital card fixing device. Please refer to Figure 1 This fixing device includes: a tray 1 and a card seat 2; the tray 1 includes: a first groove 11 for accommodating a first digital card 3; a second groove 12, which is orthogonally arranged perpendicular to the first groove 11, for accommodating a second digital card 4; the first groove 11 and the second groove 12 have partially overlapping hollowed-out parts. Therefore, the placement position of the first digital card 3 in the tray 1 is perpendicular to the placement position of the second digital card 4 in the tray 1. Specifically, the tray 1 further includes an insertion end 14 and an outer end 15, and the card seat 2 further includes an insertion surface 23.
