Abstract
The utility model relates to a shell structure capable of maintaining IC card contact pressure. The shell structure comprises a shell. An IC card seat used for reading and writing IC card data is arranged in the shell. A metal elastic piece which is in contact with an IC card chip is arranged on the IC card seat. The shell is provided with a protruding rib which enables the IC card chip and the IC card seat metal elastic piece to keep in good contact in a zone corresponding to the IC card chip. According to the shell structure capable of maintaining IC card contact pressure, the protruding rib is arranged in the zone corresponding to the IC card chip, so that the IC card chip and the IC card seat metal elastic piece are kept in good contact, successful card reading is effectively guaranteed, the shell structure capable of maintaining IC card contact pressure has the advantages of being simple in structure, easy to manufacture, low in manufacturing cost and the like, and magnitude of pressing force can be adjusted by adjusting the height of the protruding rib in practical use.
Description
Technical field
The utility model relates to a kind of shell structure that keeps IC-card contact pressure.
Background technology
In the existing IC-card seat product; more commonly adopt complete deck (namely comprising the plug-in card stopper slot); the fewer application of independent deck; and the situation of IC-card loose contact usually can appear in the deck of using separately, mainly is because the IC-card chip can't stably keep good with the metal clips of IC-card seat and contact.
The utility model content
The utility model is made improvement at the problem that above-mentioned prior art exists, be the technical problems to be solved in the utility model provide a kind of simple in structure, make easily and the shell structure of the maintenance IC-card contact pressure that cost of manufacture is low, the shell structure of this maintenances IC-card contact pressure can make the metal clips maintenance of IC-card chip and IC-card seat stablize excellent contact.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of shell structure that keeps IC-card contact pressure, comprise housing, be provided with the IC-card seat for the reading and writing IC card data in the described housing, described IC-card seat is provided with and the contacted metal clips of IC-card chip, and described housing is provided with in the corresponding region of IC-card chip and makes IC-card chip and IC-card seat metal clips keep the protruding bar that well contacts.
Preferably, described protruding bar comprises at least one lengthways of rod.
Preferably, described protruding bar comprises at least one horizontal rib.
Preferably, described protruding bar comprises at least one lengthways of rod and at least one horizontal rib, and described lengthways of rod is staggered into one with horizontal rib cross.
Further, described housing is provided with the guide vane end stop of IC-card insertion depth position, location.
Compared with prior art, the utlity model has following beneficial effect: the shell structure of this maintenance IC-card contact pressure so that the IC-card chip keeps well contacting with IC-card seat metal clips, has guaranteed the Card Reader success by in the corresponding region of IC-card chip protruding bar being set effectively; Advantages such as that the shell structure of this maintenance IC-card contact pressure has is simple in structure, make easily and cost of manufacture is low can be regulated the size of thrust in actual applications by the height of adjusting protruding bar.
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the organigram of the utility model housing.
Fig. 3 is the use state diagram of the utility model embodiment.
Among the figure: 1-housing, 2-IC card, 3-IC deck, 4-protruding bar, 5-guide vane end stop.
Embodiment
Shown in Fig. 1 ~ 3, a kind of shell structure that keeps IC-card contact pressure, comprise housing 1, be provided with the IC-card seat 3 for reading and writing IC card 2 data in the described housing 1, described IC-card seat 3 is provided with and the contacted metal clips of IC-card 2 chips, and described housing 1 is provided with in the corresponding region of IC-card 2 chips and makes IC-card 2 chips and IC-card seat 3 metal clipss keep the protruding bar 4 that well contacts.
In the present embodiment, described protruding bar 4 comprises four lengthways of rod and two horizontal ribs, and described lengthways of rod is staggered into one with horizontal rib cross; Certainly, the bar number of described lengthways of rod and horizontal rib is not limited thereto, and can increase or reduce according to actual needs.Described housing 1 is provided with the guide vane end stop 5 of IC-card 2 insertion depth positions, location.
In the present embodiment, this IC-card contact pressure controlled housing 1 structure by in the corresponding region of IC-card 2 chips (be IC-card chip area under) protruding bar 4 is set so that IC-card 2 chips keep well contacting with IC-card seat 3 metal clipss, guaranteed that effectively Card Reader is successfully.In actual applications, can regulate the size of thrust by the height of adjusting protruding bar 4, the design of those protruding bars 4 follows that product adds the principle that glue subtracts the glue difficulty easily on the mould, the little protruding bar 4 of design thrust strengthens thrust up to optimal compression power by the height that increases protruding bar 4 more earlier.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
