The metal strip 30 can be made of steel, aluminum or the like, and includes a main body segment 32 and two clamping ends 34 formed at two ends of the main body segment 32. The body segments 32 are straight strips, and each of the clamping ends 34 has an "L" shape that is generally "Z" shaped in connection with the body segments 32. Each clamping end 34 includes a connecting section 342 and a tail section 344. The connecting section 342 is inclined with respect to the main body section 32, and each tail section 344 is connected to one end of the connecting section 342 and substantially corresponding to the main body Segment 32 is parallel.

A stopper 42 is formed on the circuit board 40, and the stopper 42 has a rectangular body structure, and a wedge-shaped protrusion 422 is formed on one side thereof.

Referring to FIG. 3 and FIG. 4 , when the chip card holding structure 100 is assembled, the locking piece 20 is first assembled to the second surface 142 of the bottom plate 14 , and the abutting portion 26 of the locking piece 20 extends into the second surface 142 of the bottom plate 14 . The clamping opening 1564, the hooking portion 24 of the locking piece 20 extends into the matching hole 16 and is hooked with the end of the protrusion 162. At this time, the locking piece 20 is farther away from the card slot structure 15.

The metal strips 30 are then assembled such that the clamping ends 34 of each of the metal strips 30 are clamped to the clamping assembly 18, and the tail segments 344 of the metal strips 30 are respectively abutted against the studs 184 of the respective clamping assemblies 18. The two ends of the main body segment 32 of the metal strip 30 are respectively clamped by the catching opening 1822 of the convex body 182 of the clamping assembly 18 and the clamping groove 2224 of the locking piece 20.

Then, a chip card 200 is inserted into the card slot 152 along the inclined wall 154. One end of the chip card 200 is locked by the card cover 159, and the chip card 200 and the electrical connection plate 158 in the card slot 152 are electrically connected. Turn on.

Referring to FIG. 5, one end of the hooking portion 24 of the locking piece 20 is moved toward the slot structure 15, so that the bump 2212 of the locking piece 20 is engaged with the latching hole 1622 of the protrusion 162. buckle. The body segment 32 of the metal strip 30 moves along with the locking piece 20 such that the body segment 32 is deformed and maintains a deformed shape, and one end of the locking piece 20 is pressed by the metal strip 30. The hook portion 24 abuts against an end of the protrusion 162 , and the blocking portion 28 abuts against the inclined wall 154 .

Referring to FIG. 4 again, the abutting portion 26 of the locking piece 20 passes through the clamping opening 1564 into the cutout 1542 and abuts the chip card 200, so that the chip card 200 can be blocked. The inside of the card slot 152 is taken along the inclined wall 154, and one end of the abutting portion 26 of the locking piece 20 is abutted by the extension plate 1562.

Finally, the circuit board 40 is assembled into the housing 10 of the electronic device, so that the wedge-shaped protrusion 422 of the stopper 42 of the circuit board 40 abuts against the blocking portion 28 of the locking piece 20 to lock the locking piece 20 The blocking portion 28 is sandwiched between the wedge-shaped projection 422 and the inclined wall 154 of the card slot structure 15, so that the locking piece 20 can be prevented from being withdrawn from the clamping opening 1564. The circuit board 40 is electrically connected to the electrical connection board 158, that is, electrically connected to the chip card 200. Then, the assembly of the chip card holding structure 100 is completed.

The chip card 200 is locked by the chip card holding structure 100. Since one end of the chip card 200 is locked by the holding cover 159, the other end is abutted by the resisting portion 26 of the locking piece 20. The latching portion 20 cannot be moved because the bump 2212 of the locking piece 20 is buckled with the latching hole 1622 of the bottom plate 14 of the receiving frame 11, so that the chip card 200 is Once assembled into the card slot 152, it can no longer be easily removed.

It can be understood that the latch 42 of the circuit board 40 can be omitted because the latch 2212 of the locking piece 20 is fastened with the latching hole 1622 of the bottom plate 14 to fix the locking piece 20.

It can be understood that the two clamping members 18 for clamping the metal strip 30 on the bottom surface of the bottom plate 14 can be designed as other structures, such as including only two protrusions 184, and a radial hole is formed on the side of the protruding column 184. When assembled, the two ends of the metal strip 30 respectively pass through the radial holes.

It can be understood that the matching hole 16 of the bottom plate 14 can be omitted, and the hooking portion 24 of the locking piece 20 can be omitted, only by opening the locking hole 1622 on the bottom plate 14 and the bump 2212 of the locking piece 20. Can be combined.

It can be understood that the extension plate 1562 extending from the bottom wall 156 of the card slot can be omitted.
