Embodiment
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that execution mode is mentioned is not to restriction of the present utility model.See Fig. 1 to Fig. 3, below in conjunction with accompanying drawing, the utility model is described in detail.
Provided by the utility model
oneplant the SIM card holder of end detecting, include plastic body 1, metal bottom shell 2 and metal front cover 3, the both sides of described metal front cover 3 are provided with buckle, and described metal front cover 3 is removably connected to the top of metal bottom shell 2 by buckle, and form the accommodation space inserted for SIM card; The end of described metal bottom shell 2 is provided with the first inspection terminal 5, the end of metal front cover 3 is provided with the second inspection terminal 6, described first inspection terminal 5 is one-body molded with metal bottom shell 2, the second inspection terminal 6 is one-body molded with metal front cover 3, be provided with contact gap between the contact jaw of described first inspection terminal 5 and the contact jaw of the second inspection terminal 6, only have the first inspection terminal 5 oppressed after just can abut with the second inspection terminal 6; When SIM card is inserted into the end of SIM card holder, SIM card makes the first inspection terminal 5 and the second inspection terminal 6 contact with each other, and after SIM card is fixed on SIM card holder, the first inspection terminal 5 and the second inspection terminal 6 are in released state.When applying this SIM card holder, SIM card has two processes when grafting; First be that SIM card is inserted described accommodation space and is inserted into end always, the top of SIM card makes the first inspection terminal 5 abut with the second inspection terminal 6 and form detection signal loop mutually, therefore application system can according to loop whether conducting thus judge whether SIM card is inserted into position, this process just abuts instantaneously, and namely the conducting of the first inspection terminal 5 and the second inspection terminal 6 is formed and detects loop instantaneously; SIM card back shrinkage be fixed in accommodation space at once after abutting instantaneously, now SIM card completely grafting put in place, but the first inspection terminal 5 and the second inspection terminal 6 are in released state, do not need the detecting state that continuation is lasting.In addition, described first inspection terminal 5, second inspection terminal 6 is shaped in the end of described metal bottom shell 2, metal front cover 3 respectively, not only be beneficial to the ultra-thin and small-sized design of electronic product indoor design, electronic product, and eliminate the mould of stand-alone development for shaping described first inspection terminal 2 and the second inspection terminal 3, effectively save production cost.
In the utility model, described metal bottom shell 2 is provided with some splicing ears 4, described plastic body 1 corresponds to described splicing ear 4 place and be provided with terminal groove 7, described splicing ear 4 has elastic contact part 8 protruding upward, and described elastic contact part 8 stretches in described terminal groove 7.When being after SIM card inserts accommodating sky, the signal end of SIM card abuts with elastic contact part 8, preferably, described elastic contact part 8 is for having the flexure strip of arcwall face, therefore the arcwall face of flexure strip and the signal end contact of SIM card, effectively reduce the impulsive force of SIM card to elastic contact part 8, avoid the plastic deformation of elastic contact part 8, ensure that SIM card in use can not be short-circuited fault, ensure that the normal use of mobile phone.
Further, as shown in Figures 2 and 3, this SIM card holder also includes lock mechanism 9, the left side of described metal bottom shell 2 is provided with the clamping projection 21 for limiting lock mechanism for card 9 installation site, this clamping projection 21 forms holding tank with the left plate of metal bottom shell 2, and described lock mechanism 9 is clamped in described holding tank.Wherein, described lock mechanism 9 includes slide block 10, slide block sheet metal 11, guide rod 12 and spring 13, and described slide block 10 is provided with the draw-in groove suitable with slide block sheet metal 11, and described slide block 10 is fitting for one mutually with slide block sheet metal 11; Described guide rod 12 is fixed on the front end, left side of metal bottom shell 2, and described slide block 10 is provided with the Y shape groove 16 for blocking described guide rod 12, and described slide block 10 is free to slide by the relative guide rod 12 of described Y shape groove 16; Described slide block 10 is provided with an inserting column 101, is protruding with an insert-connecting plate 14 in the left distal end of metal bottom shell 2, the two ends of spring 13 are sheathed on described inserting column 101 and insert-connecting plate 14 respectively; The chute 22 being convenient to slide block 10 movement and the clamping slot 23 for clamping slide block sheet metal 11 is also provided with in the left side of metal bottom shell 2, the below of described slide block sheet metal 11 is provided with clamping projection (not marking in the drawings), when slide block 10 moves on to the end of chute 22 along chute 22, described clamping projection and clamping slot 23 clamping.
Further, the end of described slide block 10 is provided with the triangle push and block block 102 of anti-mis-insertion, described triangle push and block block 102 is one-body molded with slide block 10, described slide block sheet metal 11 corresponds to triangle push and block block 102 and is provided with leg-of-mutton reinforced sheet 15, and described reinforced sheet 15 is one-body molded with slide block sheet metal 11.
SIM card during insertion, by the triangle push and block block 102 of conflict lock mechanism 9 on the left of its front end, and be with movable slider 10 along chute 22 together forward slip, spring 13 is put aside elastic potential energy by compressing, guide rod 12 slides in Y shape groove 16 simultaneously, deformation occurs contact with the second inspection terminal 6 until the front end of SIM card abuts to the first inspection terminal 5, first inspection terminal 5 and form primary Ioops, therefore according to loop conducting, application system can judge that SIM card is inserted into position.Then SIM card under the effect of elastic potential energy back shrinkage once, the clamping projection on slide block 10 is connected to clamping slot 23, now all in metal bottom shell 2 splicing ears 4 are all reached with SIM card and are electrically connected.When SIM card exits by needs, driven forward SIM card is to remove the breech lock effect of guide rod 12 pairs of slide blocks 10 again, and finally under the effect of the elastic-restoring force of spring 13, slide block 10 drives SIM card to exit SIM card holder.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
