Description

The all in one card connector of the shared pin of terminal

Technical field

The utility model is relevant with electronic installation, more detailed it, be all in one card connector that refers to the shared pin of a kind of terminal.

Background technology

Present commercially available all in one card connector, the specification that can meet multiple storage card, MS (Memory Stick) for example, SM (Smart Media), MMC (Multi Media Card), SD specifications such as (Secure Digital), yet, because the contact number and the position difference of each storage card, therefore must cooperate the contact of various storage cards that many group terminal connections are set on the card connector, the number of this terminal connections is the sum total of the number of contacts of various storage cards, that is, in traditional all in one card connector, if be suitable for four kinds of storage cards, then the terminal connections number is the number of contacts sum total of these four kinds of storage cards, and is arranged at the pin of card connector root edge, is to be connected in each terminal connections in man-to-man mode in prior art.

With Fig. 5 four unification card connectors 70 commonly used extremely shown in Figure 6, have 40 pins 71, and be the card connector that typical pin 71 is connected in terminal connections 74 one to one, promptly, each card is corresponding to the pin 71 and terminal connections 74 of predetermined number, and the use that do not overlap each other to each other; This kind be connected mode one to one, can cause pin 71 numbers of card connector too many, if will add the specification of the 5th kind of storage card again, then may become about 50 pins.Because distance between must keeping necessarily between each pin, therefore can cause the volume of card connector or width can't reduce or even increase, again, if fruit is handled in the mode of dwindling spacing, though then can slightly reduce width, yet, too small between apart from the difficulty that causes on the contrary in the manufacturing, the coplane degree between pin difficulty is reached.

The utility model content

Main purpose of the present utility model is promptly at all in one card connector that the shared pin of a kind of terminal is provided, it sees through the shared some pins of the terminal on the card connector, reduce pin count purpose effect and reach, and then reduce the volume or the width of card connector itself.

Of the present utility model time a purpose is at all in one card connector that the shared pin of a kind of terminal is provided, and distance between it need not dwindle between pin is so as to easy manufacturing.

For reaching aforementioned purpose, the all in one card connector of the shared pin of a kind of terminal provided by the utility model, include: a pedestal, central authorities have a space, front end has an insertion mouth and can insert for card, the two side in this space respectively is provided with a guide rail, and by the subspace that forms different in width more than two kinds between this two sidewall and this two guide rail, and can be used to guide the card of different size; One circuit board, adhere on this pedestal, have most contacts on this circuit board, these contacts are divided at least two groups according to the specification of various cards, can be in order to cooperate the card of specification more than two kinds, be to have the part contact to be electrically connected to each other between this 2 winding point, the rear end of this circuit board has some pin solder joints, and these pin solder joints are electrically connected at the part contact of these contacts respectively; Plurality of terminals is electrically connected at the contact on this circuit board, and respectively the body portion of this terminal stretches in this space; Some pins are welded on these pin solder joints.

Embodiment

In order to describe structure of the present utility model and characteristics place in detail, lift following two preferred embodiments now and cooperate graphic explanation as back:

See also Fig. 1 to Fig. 3, all in one card connector 10 of the shared pin of a kind of terminal that the utility model first preferred embodiment is provided mainly is made up of a pedestal 11, a circuit board 21, plurality of terminals 31 and some pins 35, wherein:

This pedestal 11, central authorities have a space 12, front end has an insertion mouth and can insert for the card (not shown), this pedestal 11 respectively is provided with a guide rail 16 corresponding to the two side 14 in this space 12, and by the subspace 121,122 that forms different in width more than two kinds between this two sidewall 14 and this two guide rail 16, and can be used to guide the card (not shown) of different size;

This circuit board 21, adhere on this pedestal 11, have most contacts 22 on this circuit board 21, these contacts 22 are divided at least two groups (being to be three groups in the present embodiment) according to the specification of various cards, can be in order to the card (wherein winding point is that SD card and mmc card are shared) that cooperates four kinds of specifications, be to have part contact 22 to be electrically connected to each other between these contacts 22, the rear end of this circuit board 21 has some pin solder joints 24, and these pin solder joints 24 are electrically connected at the part contact 22 of these contacts 22 respectively;

These terminals 31 are located at this circuit board 21 with the one end respectively, and are electrically connected at the contact 22 on this circuit board 21, and respectively the body portion of this terminal 31 stretches in this space 12;

These pins 35 are welded on these pin solder joints 24.

Please consult Fig. 3 again, in the aforementioned structure, because it partly is connected to one another having between each the winding point 22 on this circuit board 21, that is 22 shared some pins 35 are put in each winding, therefore, originally the active card connector needs 40 pins, and the utility model can become by the shared technology of pin only needs 25 pins 35, and this can significantly reduce the utility model 10 integral width or volume, also need not to dwindle distance between 35 of the pins, can not cause the difficulty in the manufacturing because needs dwindle spacing.In addition, design of the present utility model can allow by shared same terminal 31, and is fashionable in different card insert, corresponding and produce the utilization of different function.For example.Fashionable at the A card insert, certain terminal 31 is to transmit signal, and fashionable at the B card insert, this 31 of certain terminal is to transmit power supply, is used for transmitting signal separately or is used for transmitting power supply separately and be not only.

Please consult Fig. 4 again, all in one card connector 40 of the shared pin of a kind of terminal that the utility model second preferred embodiment is provided is taken off embodiment before mainly generally being same as, and difference is:

This pedestal 41 more forms a plate body 48, and 51 of this circuit boards are attached at this plate body 48, and these terminals 49 are to be located at this plate body 48 with the one end, and is electrically connected at these contacts 52 of this circuit board 51.

By this second embodiment, can allow terminal 49 directly be arranged on the plate body 48 of this pedestal 41 earlier, once be welded in this circuit board 51 so as to convenient, can cross the mode of brazier and produce, and have the effect that reduces pin equally.

Via above-mentioned structure, the utility model can produce following advantage:

One, reduce pin number demand: the contact corresponding to all size card of the present utility model, Be the pin solder joint that has on the part common board, can reduce whereby pin number demand, in processing More easy, and the coplane degree of pin is that pin is also reached more easily at same plane.

Two, reduce volume: pin number demand of the present utility model is less, can reduce card and connect The volume of device itself or width.

Three, easy to manufacture: pin number demand of the present utility model is less, need not dwindle between pin Between distance, can not cause the difficulty in the manufacturing.
