Description

Electronic card coupler

Technical field

The utility model relates to a kind of electronic card coupler, especially refer to a kind of electronic installation that is applicable to, it can be in order to electronic cards such as plant smart card and card bus, and has the fool proof design, can be when smart card electronic cards misplugs in the slot of card bus electronic cards, the block effect is provided, avoids contact terminal by collision deformation, damage.

Background technology

Smart card typically refer to the prepaid card as fiscard, public telephone (stored value card), the TV programme of rectangle stored value card, save from damage card or personal identification card etc., the formation of these cards normally has a fixed standard, on the surface of every card, be evenly equipped with in appointed positions the store information that fixed with within deposit, in order to receive other electronic loop, so that carry out other electronics operation.

As Fig. 1 and Fig. 2, it is a kind of known electronic card coupler, this electronic card coupler 10a is a kind of connector of double-deck pattern, can be inserted in wherein for smartcard and two kinds of electronic cards of card bus, this electronic card coupler 10a is arranged on the motherboard 30a, but make these electronic cards mats this electronic card coupler 10a and motherboard 30a reach electric connection, so that carry out other electronics operation.

This electronic card coupler 10a is the contact terminal 11a that is provided with two rows and each row most (as four), and these contact terminals 11a is arranged on the circuit board 12a, and this electronic card coupler 10a is provided with one first slot 13a.When smart card electronic cards 20a is inserted among the first slot 13a, two row's contact points (figure slightly) that this electronic cards 20a goes up can with contact terminal 11a Elastic Contact, but make this electronic cards 20a mat electronic card coupler 10a and motherboard 30a reach electric connection.

This electronic card coupler 10a is provided with one second slot 14a in addition, and the height of this second slot 14a is many greater than the height of the first slot 13a, and is provided with a socket 15a in this second slot 14a.When being inserted among the second slot 14a, this electronic cards one end can be plugged in socket 15a when cardbus electronic cards (figure slightly), but makes this electronic cards mat electronic card coupler 10a and motherboard 30a reach electric connection, forms the connector of double-deck pattern by this.

Yet, above-mentioned known electronic card coupler 10a, because the height of its second slot 14a is greater than the height of the first slot 13a, therefore smartcard electronic cards 20a can be inserted among the second slot 14a easily, when smart card electronic cards 20a misplugs in the second slot 14a, this electronic cards 20a then can bump against the contact terminal among the socket 15a, cause contact terminal distortion, damage among the socket 15a, cause this socket 15a can't continue to use, and even make shorten many useful life of the whole electronic card coupler 10a of this socket 15a.

Therefore, as from the foregoing, above-mentioned known electronic card coupler on reality is used, obviously has inconvenience and exists with disappearance, and can treat in addition improver.

So can the improving of the above-mentioned disappearance of inventor's thoughts is that the spy concentrates on studies and cooperates the utilization of scientific principle, propose a kind of reasonable in design and effectively improve the utility model of above-mentioned disappearance finally.
