The chip card fixedly holding structure of preferred embodiment of the present invention is an example with the fixing SIM card of mobile phone, and this SIM card holding structure is in order to use with the sim card connector collocation of being located in the mobile phone.

Please be simultaneously with reference to Fig. 2 and Fig. 3, this mobile phone comprises a body 10, this body 10 comprises a first surface 102 and a second surface 104 relative with this first surface 102.Have a host cavity 120 on this first surface 102, this host cavity 120 is a rectangular cavities, and in order to the battery 20 of ccontaining mobile phone, this battery 20 can link to each other with the printed circuit board (PCB) that is positioned at host cavity 120 1 sides, so that the mobile phone electric energy to be provided.This host cavity 120 comprises a bottom surface 122, and this bottom surface 122 is between first surface 102 and second surface 104.

This SIM card holding structure comprises a holding part 30, a holding section 40 and a locking part 50, and this locking part 50 is fixed on body 10 in this holding section 40.

This holding part 30 is located on the bottom surface 122 of host cavity 120 of this body 10, and this holding part 30 is roughly a cuboid cavity, and its volume roughly volume with SIM card 60 is suitable, and it is used to hold a SIM card 60.This holding part 30 surrounds and limits SIM card 60 by 2 first fins 32 of outstanding host cavity 120 bottom surfaces 122 and 2 second fins 34 and moves, and this 2 first fin 32 and 2 second fins 34 roughly are symmetrical distribution.This 2 first fin 32 and 2 second fins 34 are all roughly L-shaped, each fin one end is tool one a vertical bar portion and a bending end respectively, the bending end of these 2 first fins 32 is oppositely arranged respectively and keeps at a certain distance away, and between two bending ends, form an opening, the bending end of these 2 second fins 34 also is oppositely arranged respectively and keeps at a certain distance away, and forms another opening.And the vertical bar portion of the vertical bar portion of this first fin 32 and second fin 34 is provided with at interval, and is positioned on the straight line.Holding part 30 bottom center are provided with a connector 140, and this connector 140 is used for being electrically connected with SIM card 60.

Please be simultaneously with reference to Fig. 2 and Fig. 3, this holding section 40 comprises two flutings 44 of two projections 42 and ccontaining this two projection 42 of difference.This two projection 42 and this two fluting 44 are divided into two groups of vertical bar portion both sides that are symmetricly set in first fin 32 and second fin 34 of holding part 30, and wherein every group comprises a projection 42 and a fluting 44.This two projection 42 is L-shaped, and it comprises a level board 422 and a vertical panel 424.This level board 422 is the part of host cavity 120 bottoms, and this level board 422 is between first fin, 32 vertical bar portions and second fin, 34 vertical bar portions, and this level board 422 is provided with two symmetrical cambered surfaces 426, and this cambered surface 426 is for preventing that scratch locking part 50 from establishing.Vertical panel 424 and this vertical connection of level board 422 1 ends, the one end protrudes the second surface 104 of body 10, as the usefulness of baffle plate.This fluting 44 becomes " ㄈ " shape for running through the through hole of host cavity bottom surface 122 and body second surface 104.

Please be simultaneously with reference to Fig. 2 and Fig. 5, this locking part 50 is an elastic component, it is fixed in holding part 30 both sides by projection 42.This locking part 50 comprises that an elasticity main leaf 52 reaches and this main leaf 52 two ends elastic side panels 54 connected vertically, and when dress was got SIM card 60, strains took place for this main leaf 52 and lateral plate 54 under external force.This main leaf 52 is roughly a rectangular slab, its middle part is provided with the square boss 522 of relative lateral plate 54 directions, and this boss 522 is integrally formed with main leaf 52, and this boss 522 is used to replace battery 20, make SIM card 60 middle parts stressed, be beneficial to SIM card 60 and better contact with connector 140.This two lateral plate 54 is integrally formed with main leaf 52, and wherein portion has a rectangle perforate 542 respectively, and by the elasticity of lateral plate 54, this perforate 542 can enlarge under the external force effect.During installation, lateral plate 54 1 ends put in fluting 44 and expose the second surface 104 of body 10, apply pulling force in lateral plate 54 two ends, this perforate 542 enlarges and overlapped the vertical panel 424 of projection 42, after the cancellation external force, perforate 542 reinstatements are enclosed within on the cambered surface 426 of projection 42

level boards

422, and 424 of the vertical panels of projection 42 become the block that prevents that locking part 50 lateral plates 54 from moving.

Please when SIM card 60 is installed, SIM card 60 be tilted to insert between locking part 50 and holding part 30 bottoms simultaneously with reference to Fig. 2, Fig. 6 and Fig. 7, SIM card 60 is replaced the main leaf 52 of locking part 50.Apply external force along SIM card 60 incline directions, locking part 50 deforms, and makes SIM card 60 and holding part 30 bottom surfaces keep this SIM card 60 1 ends under the certain angle to slide into and replace the bending end of these 2 first fins 32 down in the vertical bar portion guiding of this 2 first fin 32.SIM card 60 is put down, and locking part 50 recovers automatically, is pressed on the SIM card 60.Battery 20 is loaded onto, and the boss 522 that it replaces locking part 50 makes SIM card 60 middle parts stressed, and SIM card 60 contacts closely contact with the pin of connector 140.

When taking out SIM card 60, earlier battery 20 is opened, by the elasticity of locking part 50, between 2 first fins 32 or the opening part that forms between 2 second fins 34 with up perk of SIM card 60, the contact of SIM card 60 tilts to take out with SIM card 60 by external force away from holding part 30 bottom surfaces.

Alternate manner can be adopted in the holding section 40 that is appreciated that locking part 50, can directly melt by glue or heat lateral plate 54 is fixed on the dividing plate 10, also two lateral plates 54 can be passed body 10 host cavities 120 bottoms and be connected and fixed for 104 times in second surface; Holding part 30 can be depressed in the bottom surface of host cavity 120, moves by sidewall restriction SIM card 60.

Compare prior art, described SIM holding structure is fixed in SIM 60 in the holding part 30 by a snap lock firmware 50, utilize its elasticity, dress makes the contact of SIM 60 avoid being worn when getting SIM 60, increased the service life of SIM 60, the boss 522 that utilizes snap lock firmware 50 middle parts to arrange makes SIM 60 middle parts stressed, has improved the yield that is connected with connector 140, and it is simple in structure, low cost of manufacture.
