Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, and a kind of electronic card coupler that provides more than one electronic cards to plant is provided especially.

[background technology]

The electronic cards that is applied at present in the Portable memory storage mainly can be divided into the disk sheet of magnetic memory, light storing technology and the erasable formula internal memory three major types of semiconductor technology.Wherein popularize the most with the product of Flash Memory kind again and also be subjected to most attracting attention of dealer and consumer, generally be referred to as storage card, such as: XD card (eXtreme Digita Card), SD (Secure Digital) card, MMC (MultiMedia Card) card, MS (Memory Stick Card) card etc.Because this series products no matter the convenience that carries, power saving, data preserve and the performance of functional characteristic such as message transmission rate on, it is many all far to surmount above-mentioned two kinds of traditional storing medias.Be widely used on the action message household appliances such as digital camera, digital camera, PDA at present.

State in the use when storing card, often will realize the electric connection of storage card and action message household appliances by electronic card coupler.But the memory khaki connecting point position of each specification is neither together, so the required cooperation of memory card of different size is pegged graft to such an extent that electronic card coupler is then inequality, so existing electronic card coupler, it only can provide the electronic cards slot of single specification, and can't be with the function of the electronic cards slot that plurality of specifications is provided, make electronic card coupler be restricted on using, and the essential corresponding electronic card coupler of individual design of the electronic cards of each specification, can make that production cost significantly promotes, cause the dealer to perplex greatly.

For consumption demand and promotion storage card in response to market can be widely used on the more products, and can integrate the storage card of various different sizes, the existing at present electronic card coupler that can support multiple different size storage card again.See also Figure 10, its a kind of existing electronic card coupler 1 ' that plurality of specifications is provided comprising: insulating body 10 ' and group are located at the first terminal 21 ', second terminal 22 ', the 3rd terminal 23 ' in this insulating body 10 '.Wherein the first terminal 21 ', second terminal 22 ', the 3rd terminal 23 ' electrically contact with the electronic cards (not icon) of different size respectively.During use, only need electronic cards is inserted in the electronic card coupler 1 ', but because the bearing of trend of the first terminal 21 ' is opposite with the direction of insertion of electronic cards, electronic cards will be conflicted with 21 ' the positive interference of the first terminal, very easily firmly cause the part terminal to be subjected to the undue influence excessive deformation of electronic cards thus, and then influence the terminal coplane degree because of the user is improper.And because the first terminal 21 ' can be supported the electronic cards of SD specification and the electronic cards of two kinds of specifications of MMC, after use repeatedly, the problem that easily causes terminal to subside again, and then cause the loose contact of electronic cards, the actual life of also reducing electronic cards and electronic card coupler.

[summary of the invention]

A purpose of the present utility model, be to provide a kind of terminal of electronic card coupler, it promotes the terminal non-deformability and avoids terminal and electronic cards is positive contacts according to the direction of insertion of electronic cards in order to the intensity of the adjutage of reinforcement terminal by increasing by a kink, makes thus between electronic cards and the connector to keep excellent electrical property to be connected.

The utility model provides a kind of electronic card coupler for solving the technological means that prior art problems adopted, and it includes an insulating body, group is located at the terminal group in the insulating body, and a shielding casing covers on body.

Wherein, this terminal group is provided with several terminals, above-mentioned terminal comprises main part respectively, be bent to form the kink of certain knuckle by an end of main part, this kink is in order to the intensity of reinforcement adjutage, the adjutage that extends forward by kink, and the contact site that is positioned at the adjutage top, this contact site has a sliding surface, the contact-making surface of this sliding surface and electronic cards is suitable, when making the insertion of electronic cards, the contact-making surface of electronic cards is little by little along the sliding surface slippage of terminal, and the moment that electronic cards and contact site produce equals the resultant couple that adjutage and kink produce.Promote the resistance to deformation function of terminal thus and obtain preferable terminal coplane degree, and the bearing of trend of adjutage is consistent with the direction of insertion of electronic cards, so avoid terminal to conflict with positive interference of the contact-making surface of electronic cards.

Via the technological means that the utility model adopted, the terminal that can guarantee electronic card coupler is through repeatedly plugging the function that still can remain unchanged shape.Guarantee the good electrical performance of electronic cards and electronic card coupler and the useful life of prolongation electronic cards and electronic card coupler thus.

For making the purpose of this utility model, structural feature and function thereof there are further understanding, cooperate diagram to be described in detail as follows now:
