The chip card 200 is mounted on the reinforcement board 30 and electrically connected to the protruding part of the flexible circuit board 20 .

The supporting frame 10 is formed with a pair of guiding walls 11 and blocking walls 13 , and the pair of guiding walls 11 are bent and extended from opposite sides of the supporting frame 10 and together form a path for inserting the chip card 200 . The blocking wall 13 is disposed at one end of the pair of guiding walls 11 and forms a receiving space 15 with the pair of guiding walls 11 . The receiving space 15 communicates with the mounting groove 301 correspondingly.

The flexible circuit board 20 is installed on the supporting frame 10 and accommodated in the receiving space 15 . The flexible circuit board 20 includes a body 21 , a plurality of metal springs 23 disposed on the body 21 , and a connecting terminal 25 electrically connected to the metal springs 23 . The body 21 is made of insulating material.

The body 21 includes a first surface 211 and a second surface 213 opposite to each other, and positioning holes 215 are defined on opposite sides. The first surface 211 is adhered to the support frame 10 , and the two positioning holes 215 are fastened to the guide wall 11 . A plurality of metal domes 23 are juxtaposed on the second surface 213 and located between the pair of positioning holes 215 for electrical contact with the chip card 200 . Each metal dome 23 includes a foot portion 231 and a contact portion 233 bent and extended from one side of the foot portion 231 . The leg portion 231 of the metal dome 23 is soldered to the body 21 and electrically connected to the connection end 25 . The connection end 25 is electrically connected to a circuit board (not shown). In this embodiment, the metal elastic pieces 23 are in two groups.

The reinforcement board 30 is accommodated in the receiving space 15 and adhered to the second surface 213 of the main body 21 . The reinforcing plate 30 includes a plurality of locking portions 31 arranged in parallel, and defines a limiting groove 33 between two adjacent locking portions 31 , or between the locking portions 31 and a side wall. Receiving grooves 35 communicating with the plurality of limiting grooves 33 are defined on the reinforcing plate 30 . The engaging portion 31 is approximately T-shaped, and includes a connecting end 311 and an extending end 315 extending along the connecting end 311 . The extending end 315 is wider than the connecting end 311 . Each limiting groove 33 includes a connection groove 331 located between two adjacent connection ends 311 or between the connection end 311 and the side wall, and a connection groove 331 located between two adjacent extension ends 315 or between the extension end 315 and the side wall The extension slot 333 between them. The extension slot 333 is narrower than the connection slot 331 . The receiving groove 35 is defined on one side of the extending end 315 and communicates with the plurality of extending grooves 333 . The leg portion 231 of each metal dome 23 is received in the connecting groove 331 on the reinforcing plate 30 . The contact portion 233 of the metal dome 23 is partially accommodated in the extending groove 333 and extends upward toward the receiving groove 35 . When the contact portion 233 of the metal dome 23 is in contact with the smart card 200 , the contact portion 233 is bent toward the receiving groove 35 . The reinforcing plate 30 is made of insulating material.

During assembly, the first surface 211 of the flexible circuit board 20 is bonded to the support frame 10 , and the two positioning holes 215 are fastened to the pair of guide walls 11 . The reinforcement board 30 is covered and glued on the second surface 213 of the flexible circuit board 20 . The leg portion 231 of the metal dome 23 is accommodated in the limiting groove 33 on the reinforcing plate 30 . The contact portion 233 of the metal dome 23 protrudes above the receiving groove 35 . The support frame 10 is mounted on the electronic device casing 300 .

When in use, insert the chip card 200 into the receiving space 15 along the path of the two guide walls 11, and abut against the blocking wall 13, so that the chip card 200 is clamped on the guiding wall 11 and the blocking wall 13 between. At this time, the smart card 200 is pressed and held against the contact portion 233 of the metal dome 23 .

Since the reinforcing plate 30 is covered on the flexible circuit board 20, and accommodates the metal dome 23 through the limiting groove 33 on it, thereby preventing the chip card 200 from pushing against the metal dome 23 when it is inserted, so that the chip card holding structure 100 is not easily damaged. , prolonging the service life of the portable electronic device 100 . In addition, since the limiting groove 33 accommodates the leg portion 231 of the metal dome 23 therein, the thickness of the chip card holding structure 100 is relatively reduced, which is beneficial to thinning the portable electronic device 500 . Since the support frame 10 can accommodate and hold the chip card 200 through the guide wall 11 and the blocking wall 13 , there is no need to provide an additional engaging mechanism for holding the chip card, which saves costs.

It can be understood that the reinforcement board 30 can be mounted on the supporting frame 10 and covered on the flexible circuit board 20 by means of engagement.

It can be understood that the connecting groove 331 and the extending groove 333 can be designed to have the same width.

In addition, those skilled in the art can also make other changes within the spirit of the present invention. Of course, these changes made according to the spirit of the present invention should be included in the scope of protection claimed by the present invention.
