Adjacent to one side of the terminal module 40, a sliding channel 43 is defined extending along a card insertion direction. Corresponding to the screw hole of the first insulating housing 2, a pair of screw holes 30 are defined on the opposite ends of the second insulating housing 3.
As shown in FIG. 4 and FIG. 5, the structure of the first ejecting mechanism 5 and the second ejecting mechanism 5′ are almost the same. The first ejecting mechanism 5 and the second mechanism 5′ comprises, respectively, a bracket 50, 50′, a pushing member 51, 51′ surrounded by corresponding brackets 50, 50′, a subordinating member 52, 52′ actuated by corresponding pushing member, a rotary member 53, 53′ and an ejecting member 54, 54′. In the bracket 50, 50′, a limiting section (not shown) is formed, respectively, for dominating the push member 51, 51′ and the subordinating member 52, 52′ moving. A plurality of stabbing pieces 501, 501′ are provided on the upper portion and the lower portion of the bracket 50, 50′, respectively. On the rotary member 53, 53′, an axis part 530, 530′ is formed according with the combining section 210 of the first insulating housing, respectively. The ejecting member 54, 54′ has a pushing section 542, 542′ protruding into the first card slot 80 and the second card slot 90, and a joining section 541, 541′ connecting the ejecting member 54, 54′ with the rotary member 53, 53′, respectively. The pushing member 542, 542′ are capable of engaging with corresponding card directly.
Together with FIG. 1 to FIG. 5, the relationship of the elements of the card connector 100 as described above will be illustrated in flowing segment.
