Description

The shared electric connector of multiple IC chip card

Technical field

The present invention is meant the shared electric connector of a kind of IC of connection chip card especially relevant for a kind of electric connector.

Background technology

The IC chip card is widely used in our daily life at present, for example credit card, ATM card, phonecard or the like all are, see also Fig. 1, the present big IC chip card of traditional type (hereinafter to be referred as kilocalorie 10) that widely uses, its width is about 5cm, which is provided with a contact 11, these contact 11 instrument account for the sub-fraction of card area, so obviously this kilocalorie 10 still has the very big space of simplifying.

Seeing also Fig. 2, is the little IC chip card (above abbreviation lesser calorie 15) of a new generation, half of the only about kilocalorie 10 of these lesser calorie 15 width, and comparatively compact, it is comparatively convenient to carry, and still has enough areas that one contact 16 is set on it.

Because the specification difference of large and small card, the machine that is suitable for kilocalorie 10 then can't use for lesser calorie 15, the same machine that is suitable for lesser calorie 15 then can't use for kilocalorie 10, two kinds of boards are inconsistent, under the operating position of market, the inconsistent board of this kind will cause user's inconvenience to large and small card like this simultaneously.

Embodiment

See also Fig. 3 and Fig. 4, the shared electric connector of multiple IC chip card of the present invention, it can make, and a big IC chip card (hereinafter to be referred as kilocalorie) and is that little little IC chip card (hereinafter to be referred as lesser calorie) all can insert connection than this big IC chip card, it includes: a plastics pedestal 20, several terminals 35, two limit elements 40, a guide plate 50, two trip shell fragments 60, wherein: form one in the plastics pedestal 20 and can block shared draw-in groove 21 more, the front end of this draw-in groove 21 is provided with one and inserts mouth 22, and the size of inserting mouth 22 is corresponding with the width of big IC chip card; One kilocalorie can insert mouth 22 and enter this draw-in groove 21 location.

Several terminals 35 is to be located on this plastics pedestal 20.

Two limit elements 40 are metal clips, its from bottom to top fastening be located at insertion mouth 22 near the draw-in groove 21 of this plastics pedestal 20, has elasticity springing up and down, the one end is provided with

fastening portion

41 and 20 fastenings of plastics pedestal, its stage casing is provided with higher main body 42, the other end is provided with lower Extendible flake 43, two limit elements 40 extend in parallel in the pedestal and are a spacing by inserting mouthful, the spacing of this two limit element 40 is corresponding with the width of little IC chip card, and its both sides can be 42 limit lateral positions of main body of this two limit element 40 and form the fastening effect when a lesser calorie inserts this draw-in groove 21.

This guide plate 50 is to be provided with drive-connecting shaft 54 to be articulated on the pedestal and to be positioned at and insert mouthfuls 22, this guide plate is provided with a recess 51 and thin card 52 is established in both sides, these recess 51 dual side-edges are provided with and import inclined-plane 53, the width of this recess 51 system is to spacing that should two limit elements 40, and lesser calorie be in harmony can be from these recess 51 processes.

Please cooperate and consult Fig. 5, this two trips shell fragment 60 from bottom to top fastening is located at the both sides of plastics pedestal 20, this guide plate 50 of its trip is erectility, it is provided with a location division 61 and an elastic arm 62, fastening is used in plastics pedestal 20 in this location division 61, and the front end of this elastic arm 62 is provided with guiding incline 65 and is formed with formation one recess 64 between two protuberances, 63, two protuberances near front end, but the card 52 of these these guide plate 50 both sides of recess 64 fastenings makes guide plate 50 be erectility.

By above structure, see also Fig. 6 and Fig. 7, when kilocalorie 10 inserts draw-in groove 21, its both side edges can compress the guiding incline 65 of this trip shell fragment 60, trip shell fragment 60 is flicked laterally and break away from the card 52 of buckle guide plate 50, so this guide plate 50 can pivot and depress this limit element 40, so can insert draw-in groove 21 to the location.

See also Fig. 8 and Fig. 9, when lesser calorie 15 inserts draw-in groove 21, owing to these guide plate both sides are erectility for these two trips shell fragment, 60 fastenings, so it can insert lesser calorie 15 according to the recess 51 of guide plate 50, its both sides can be 42 limit lateral positions of main body of this limit element 40 and form the fastening effect, thus can be very clear and definite be positioned in the draw-in groove 21.

Have the following advantages by above explanation the present invention:
