Embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to Fig. 2-Fig. 7, contact making device one preferred embodiment of the present utility model is proposed, described contact making device is installed on the IC-card deck, comprises base 100, spring stylus 200 and this spring stylus 200 is installed on the first fixed axis 300 of base 100.Described base 100 is provided with the some grooves 110 that extend along its length, groove 110 quantity are decided according to the actual requirements, and the groove 110 in the present embodiment has two rows, four totally eight of every rows, and each groove 110 bottoms also are provided with through hole 120, and groove 110 sidewalls are provided with the first perforation 130.Spring stylus 200 also has eight, it has one and is wound in helical form and is placed in the interior spring body 210 of described groove 110, the first fixed axis 300 has two, each root passes same row's four grooves 110 and spring body 210 by the first perforation 130 of groove 110 sidewalls, thereby spring body 210 is fixed in groove 110.And spring body 210 1 ends extend a pin 220 by the through hole 120 in groove 110 to described base 100 bottoms, and this pin 220 is used for and the circuit board conducting; Spring body 210 other ends are to base 100 oblique extension one haptic elements 230 in top, and it protrudes from backward these base 100 directions bendings of described base 100, and the position of described haptic element 230 and IC-card 10 butts is the contact 231 with the chip conducting of IC-card 10.
In addition, except being fixed in spring body 210 in groove 110 with the first fixed axis 300, can also buckle be set at groove 110 sidewalls, and the tubular, hollow of spring body 210 itself can be used as draw-in groove, thereby form a buckle structure, therefore can spring body 210 be fastened in groove 110 by buckle.
Accordingly, the present embodiment realize spring stylus 200 directly and IC-card 10 and circuit board conducting by spring stylus 200 elastic forces own, so stability is higher by pin 220 and contact 231 are integrally formed at spring stylus 200; Simultaneously, tilt due to haptic element 230 with IC-card 10 butts, with respect to vertically being connected to IC-card 10, the contact 231 on haptic element 230 is less with the wearing and tearing of IC-card 10, is conducive to extend the useful life of IC-card 10 and contact making device.
Further, in the present embodiment, contact 231 is curved, to reduce friction, reduces the wearing and tearing to IC-card 10; Contact 231 is gold-plated simultaneously, improves the anti-wear performance of contact 231.Thereby, further extended useful life of IC-card 10 and contact making device.
Further, base 100 holds 150 for the end that IC-card 10 passes through at first for entering card, and the haptic element 130 of the present embodiment tilts toward entering card end 150 directions.Usually slower when card enters, but when card release, the user is extracting rapidly sometimes, if haptic element 130 toward tilting away from entering card end 150 directions, extract rapidly the tractive effort of card might cause spring stylus 200 upsets and impact stable.The present embodiment tilts effectively to have avoided this problem toward entering card end 150 directions with haptic element 230, has further improved the stability of contact making device.
Further, the contact making device of the present embodiment also comprises two second fixed axis 400, every the second fixed axis 400 is interspersed in four grooves 110 of same row by the second perforation 140 that is arranged at groove 110 sidewalls, haptic element 230 ends that are fixed in the spring stylus 200 in groove 110 bend in groove 110 and form a barb 232, and this barb 232 is fastened on the second fixed axis 400.Thereby, the two ends of spring stylus 200, namely spring body 210 and haptic element 230 all are fixed in groove 110, so IC-card 10 can not cause the upset of spring stylus 200 when inserting and extracting, and have further improved the stability of contact making device.Simultaneously, the haptic element 230 of spring stylus 200 is held 150 directions or tilts all can away from entering card end 150 directions toward entering card at this moment.
In addition, haptic element 230 can also be arranged to the entering card direction inclination certain angle of IC-card 10 not that to enter the card direction parallel with this; Perhaps, a through hole is set in groove 110 again, haptic element 230 ends pass and form barb after the through hole of groove 110 and deviate to prevent it.Above scheme can solve the problem of spring stylus 200 upsets.
