post 251 and the second protrusion post 252. The guide member 52
can slide freely in the heart-shape slot 26.
[0023] Referring to FIGS. 5 and 6, when the SIM card 200 is
assembled with the card connector 100 of the present invention, the
tray 30 is pulled firstly. The outer tray 33 is pulled down, and
the second protrusions 353 are loosed from the second locking holes
323, so that the outer tray 33 pivots downwardly. Then, the SIM
card 200 is put in the receiving groove 31 on the inner tray 32.
The outer tray 33 pivots upwardly until the outer tray 33 and the
inner tray 32 are horizontally connected together. In the meantime,
the second protrusions 353 are received in the corresponding second
locking holes 323 to implement the connection between inner tray 32
and the outer tray 33. The tray 30 is pushed inwardly, and the rear
end 30 of the tray 30 leans against the card ejecting arm 511 of
the card ejecting mechanism 50, so that the card ejecting arm 511
forces the slide block 51 to slide backwardly and the elastic
member 53 is compressed to store elastic energy. The guide member
52 slides in the heart-shaped slot 26 until the slide block 51 is
locked at a latch position. The elastic stopping sheet 113 leans
against the guide member 52 for preventing the guide member 52 from
popping out. The sheets 111 are fixed in the locking slots 312, and
the assembling of the SIM card 200 is achieved. The disassembled
processes of the SIM card 200 are opposed to the above-mentioned
assembled processes of the SIM card 200 and not described in detail
herein.
[0024] The tray 30 is formed by pivotally connecting the inner tray
32 to the outer tray 33, and therefore the card connector 100
according to the present invention can be used more conveniently
than the traditional card connector.
[0025] As is understood by a person skilled in the art, the
foregoing preferred embodiments of the present invention are
illustrative rather than limiting of the present invention. It is
intended that they cover various modifications and similar
arrangements be included within the spirit and scope of the
appended claims, the scope of which should be accorded the broadest
interpretation so as to encompass all such modifications and
similar structure.
