Description

The structure of card connector detecting terminal

Technical field

The structure of the relevant a kind of card connector detecting terminal of the utility model refers to a kind ofly when moving back card for memory card especially, can not produce the sense terminal minor structure of short circuit.

Background technology

The memory card connector that habit has, it can be made as various kenels such as single plug-in card or compound plug-in card, so that single memory card or the general card-reading function of multiple memory card to be provided; Habit has memory card connector, it is formed main city and comprises that an exhausted first pedestal and most group connect terminal, and be provided with single slot or compound slot with multi-form memory card coupling, after memory card inserts, can with connect terminal and form the effect of depositing that connects and give information.

Above-mentioned habit has memory card connector, also there is memory card after inserting card connector, must connect one or two detecting terminal earlier, makes and activate data access, so card connector is provided with one group of detecting terminal in addition in this insulating base, could cooperate memory card to produce function.Promptly as shown in Figure 1, habit has the memory card connector 1 with detecting terminal, its correspondence is located at one of them selected terminal 12 that connects of insulating base 11, set up one again and be alternate detecting terminal 13 up and down, after memory card 2 is inserted, conductive junction point 21 on its memory card is except that connecting terminal 12 and be the conducting that contacts with selected, and can compress touch the detecting terminal 13, order detecting terminal 13 is subjected to contacting with connecting terminal 12 formation to the active force of lower compression, obtains detecting function by this and makes the conducting of telecommunication loop.

And this memory card connector more than 1 can be combined with a trip mechanism (not indicating among the figure), make memory card withdraw from card connector, it utilizes the push rod mode to move back card or repeated presses memory card mode is moved back card designs such as (being commonly called as Push-Push), all is in order to provide the user at operational convenience.Wherein the Push-Push mode is moved back the design of card, its be haply utilize that memory card interlock slide after inserting card connector for example carries out " heart type " move back the card path, the pulling force that moves back card path and elastic parts that mat is somebody's turn to do " heart type " produces the effect of location and reduction, because this technology partly just will not be given unnecessary details at this to continue to use for many years.

After having had above-mentioned this Push-Push mode to move back the design of card, though solved the unhandy problem of user, but because the active force of elastic parts is excessive in the trip mechanism, flown situation outside card connector and produce memory card by bullet, when causing memory card to withdraw from easily, this situation produces skew, make conductive junction point 21 on the memory card 2 may be simultaneously can connect terminal 12 and contact, and cause the detecting short circuit with two.

The utility model content

In view of this, the purpose of this utility model is: provide a kind of and when moving back card, can not produce the sense terminal minor structure of detecting for memory card.

For reaching above-mentioned purpose, card connector of the present utility model includes at least: one is provided with the pedestal of accommodation space, its accommodation space one side is provided with retreat-card device, earth terminal and detecting terminal, this retreat-card device is provided with one and passes piece, guide rod and guide groove, its guide groove also can supply guide rod locating slip thereon, be provided with an elastic parts and pass between piece and pedestal, its earth terminal can form an appropriate gap with detecting between terminal or closely contact, guide rod slippage in guide groove when moving back card, can pass the earth terminal displacement, so that it is with the detecting termination contact or do not contact and produce detection signal, and then the telecommunication loop is closed, can not produce short circuit in the time of can allowing memory card move back card.

The beneficial effects of the utility model are: can obtain a kind ofly when moving back card, can not producing the sense terminal minor structure of short circuit for memory card.
