Description

  The present invention relates to a memory card capable of automatically correcting an interface standard, and in particular, has a function of separately expanding a communication interface in addition to a standard interface and automatically correcting the standard of the connection size between the communication interface and the read / write device. Related to memory cards.

Small memory card that currently existing on the market, for example SD, CF, SM, MMC, X D, type, etc. MS is very large, common needs and features of these small memory card, while minimizing the size Therefore, the capacity is increased as much as possible, and the capacity has already reached 1 GB or more.
Although memory cards are making significant strides in capacity, each memory card is in principle only connected to read / write devices such as computers, electronic products, etc., rather than only to its own specific protocol. When it is desired to connect different memory cards to the computer, a card reader of the same protocol must be mediated and cannot be directly connected to the computer.

In order to solve the above problem, the industry is trying to develop a memory card having two types of connection interfaces.
One of these interfaces simply connects to the computer via a conversion module that conforms to the appearance of the interface.
The above-mentioned method certainly solves the problem that the memory card cannot be directly connected to the computer. However, a more advanced concept is that if the memory card itself can be directly inserted and connected to the interface port of the computer, the convenience in use will be further improved, that is, the other interface port will be This interface port is added directly to the memory card, and this interface port can be directly inserted and connected to the interface connector of the computer.
Before realizing this concept, the difference between the standard of the memory card itself and the standard of each interface currently used in computers must be considered.

Currently, the most popular interface connector for computers belongs to USB (Universal Serial Bus), and if a memory card is equipped with USB, it can be directly connected to many computers. However, it is the standard difference between the memory card itself and the USB interface port that needs to be taken into consideration, and it affects the normal use of the original interface of the memory card due to the fusion with the standard of the extended interface. There should be no such thing.
FIG. 18 discloses a USB interface plug (80). The front end of the USB interface plug (80) is a rectangular metal shell (81), and an insulating plate (82) is provided on the inner bottom surface of the shell (81). And four sets of terminals (820) which are data lines D +, D-, power supply lines VCC and GND, respectively, are provided on the insulating plate (82).

  When the USB interface type is divided into male and female, the USB interface plug (80) is a male plug, and a USB interface connector (90) (shown in FIG. 19) normally provided on a computer is a female plug. This USB interface connector (90) is provided with an insulating plate (92) at the upper end portion of a rectangular metal housing (91), and the upper surface of the insulating plate (92) and the inner upper surface of the housing (91) Four sets of elastic contacts (920) corresponding to the four sets of terminals (820) on the USB interface plug (80) are provided on the bottom surface of the insulating plate (92). The USB interface plug (80) inserted into the housing (91) is applied to the top and bottom ends of the housing (91). And a housing for fixing (91) four sets of positioning springs projecting respectively inside (910) is provided.

FIG. 20 discloses a state after the USB interface plug (80) is inserted into the USB interface connector (90).
When the shell (81) of the USB interface plug (80) is properly inserted into the housing (91) of the USB interface connector (90), the insulating plate (82) in the shell (81) is inside the housing (91). The elastic contact (920) on the insulating plate (92) is correspondingly electrically connected to the terminal (820) on the insulating plate (82) by being inserted between the bottom surface and the insulating plate (92). So that they are electrically connected.

As can be understood from the above description, in the case of the USB interface plug (80), the action of the shell (81) is in positioning, and it is substantially electrically connected that the insulating plate (82) and above it. Terminal (820).
Based on size considerations, if you want to integrate the USB interface plug on the memory card, only the insulating plate (82) that actually achieves the electrical connection purpose by providing the terminal (820) on the top It is possible to select
However, even if only a structure for actually achieving the electrical connection purpose is selected, the standard is still not compatible with the memory card.
As shown in FIG. 19, the clearance between the inner bottom surface of the housing (91) of the USB interface connector (90) and the insulating plate (92) thereabove, that is, the insulating plate (82) of the USB interface plug (80) is provided. In order to make the insertion space easy to insert, the height of the space is substantially larger than the thickness of the insulating plate (82), but a positioning spring (910) for locking is separately provided. ing.
Here, if the insulating plate (82) is integrated on the memory card, its thickness must correspond to the gap between the inner bottom surface of the housing (91) and the insulating plate (92) above it. If the thickness is insufficient, play may occur and contact failure may occur.
However, as long as it is integrated on the memory card, the standard requirement of the USB interface itself cannot be satisfied.
Taking an SD card as an example, the width / length / thickness are 24 mm, 32 mm, and 2.1 mm in this order, while the USB interface connector (90) has a bottom surface inside the housing (91) and an insulating plate (92 above it). ) Is about 2.5 mm.
In other words, when only the part that realizes electrical connection with the USB interface is integrated into the SD card and conforms to the standard of this SD card (thickness is 2.1 mm), the USB interface connector is about the thickness. Obviously, it is not enough to insert and lock firmly into (90) and will not meet the standards of the USB interface.

In order to correct the difference in the standard that occurs after the USB interface plug is integrated on the memory card, the inventor previously referred to “a memory card with an interface standard correction function and its standard in Taiwan Patent Application No. 0941099961. A specific solution is proposed by filing a patent for the “protective case” invention.
The above patent mainly provides a protective case for accommodating a memory card therebetween.
This memory card is provided with a first interface connection port at one end and a second interface connection port at the other end opposite thereto, and a protective cover is a shell and cover that can accommodate the memory card therebetween. And the second interface connection port of the memory card is exposed to the outside of the shell, and the shell extends outward at one edge of the opening to form a correction pad. Is suitable for being arranged at the bottom of the second interface connection port of the memory card, so as to compensate for the thickness of the second interface connection port and the size of the corresponding interface connector provided in the read / write device It conforms to the standard.

  As can be understood from the contents of the above-mentioned patent, the so-called second interface connection port is a USB interface plug, and the thickness of the second interface connection port is compensated with a correction pad on the protective case, so that a standard USB can be used. Because it conforms to the basic standard of interface plug, it can perfectly match the interface connector of the corresponding protocol on the read / write device to obtain a robust insertion connection, and the structure is simple, convenient and practical For this reason, a patent (Taiwan Invention Patent No. 1249884) has been obtained.

  However, the correction means in the above patent is effective only by a protective case provided outside the memory card. Although the structure is simple and easy to use, the correction means is built in the memory card. However, it is even more convenient for the user.

  Accordingly, the main object of the present invention is to correct the thickness of the communication interface port provided at one end by a correction mechanism built in the memory card, so that the memory card is connected to the interface connector of the read / write device by the communication interface port. A memory card capable of automatically correcting an interface standard that can be completely matched with the size standard of the interface connector and obtain a firm insertion connection relationship when inserted into the memory card.

The main technical technique adopted to achieve the above object is that the memory card is

  Since the correction mechanism is incorporated in the memory card, the communication interface port on the memory card is matched with the interface connector of the corresponding protocol on the read / write device without requiring any external auxiliary member, A firm insertion connection effect can be obtained.

  The correction mechanism has an opening formed in the first or second surface adjacent to the second end of the shell, and a support body on which a plurality of conductive contacts as communication interface ports are provided is provided in the opening. One or more biasing means are further provided below the support in the shell to support the conductive contact on the support to an appropriate height by being supported between the support and the inner bottom surface of the shell. .

  The correction mechanism has an opening formed in a first or second surface adjacent to a second end of the shell, and a push-up support body facing the conductive contact provided on the second or first surface of the shell One or more energizing forces that push through the openings from the inside to the outside and push up the conductive contacts on the opposite positions to the appropriate height when the push-up support is pushed outward. Means are further provided between the push-up support and the inner bottom surface of the shell.

  A plurality of through grooves are formed in the first or second surface adjacent to the second end of the shell, and metal pieces constituting conductive contacts of the communication interface port are respectively provided in the respective through grooves, The correction mechanism is composed of an urging plate provided on at least one end of each metal piece, and each urging plate is supported by being pushed up between the inner bottom surfaces facing each other to apply an urging force to the metal piece. In a normal state, each metal piece protrudes from the through groove and is positioned at an appropriate height to match the interface connector of the corresponding protocol. Is shrinking.

  The present invention is applied to various memory cards that extend communication interface ports in addition to existing interface ports. However, in order to help understanding, the following embodiments will be described using an MS DUO card as an implementation target. However, it is also stated in advance that this is merely a disclosure of an example that can be implemented and does not have a meaning to limit the application object of the present invention.

The MS DUO memory card disclosed in FIGS. 1 and 2 is provided with a standard interface port (11) on one end of one surface of the planar shell (10), and further a communication interface on the other end of the same or opposite surface. A port (12) is provided.
In this embodiment, the communication interface port (12) is a USB interface, and only the structure of the electrical connection portion in the standard interface port is employed. That is, it has a plurality of terminals on the insulating plate.
In this state, the communication interface port (12) is adapted to the standard of the MS DUO memory card in terms of thickness, but the USB interface port is narrower than the MS DUO memory card, so the communication interface port (12 ) May be located at the center or side of the rear end of the shell (10) of the memory card.
In the present embodiment, the communication interface port (12) is located in the center of the memory card shell (10), and the MS DUO memory card has a standard size. Even if it is expanded, conformity to the conventional standard should be made.
Since the communication interface port (12) uses the space at the rear of the shell (10), the length conforms to the MS DUO memory card standard, but a notch is formed at the rear of the shell (10). By this, it completely conforms to the size standard of the MS DUO memory card. That is, a flat slide cover (20) is also fitted on the shell (10), and the height / width of the slide cover (20) is provided with the standard interface port (11) of the shell (10). The slide cover (20) is slidable from an intermediate position of the shell (10) toward one end where the communication interface port (12) is provided, so that the end of the end The width is compensated, and this is brought close to one end having the standard interface port (11), and the outer size of the shell (10) is approximated to the standard of the memory card. When it is desired to insert and connect to the reading / writing device using the communication interface port (12), the slide cover (20) is pushed backward to expose the communication interface port (12), thereby reading / writing device. Insert and connect.

  The above-described configuration is the basic structure of the present invention. The main technical feature of the present invention is to compensate for the difference in standards between the communication interface port (12) and the standard USB plug.

The communication interface port (12) belonging to the USB interface is integrated with the memory card. If the MS DUO memory card is taken as an example, the standard thickness is 1.6 mm, but the thickness of the USB plug (part of the insulating plate) Only) is about 2.0 mm, and there is a difference of 0.4 mm between them.
Such a difference in thickness tends to cause backlash due to a gap when the communication interface port (12) is connected to the USB interface port connector, and in some cases affects the normal transmission of data.
Therefore, the present invention provides a correction mechanism at a position corresponding to the communication interface port (12) in the shell (10), and when the communication interface port (12) is used, the thickness difference is reduced. It compensates automatically. Specific technical contents and various embodiments that can be implemented will be described in detail below.

Please refer to FIG. 1 to FIG. 5 which disclose the detailed structure and operation method of the first preferred embodiment according to the present invention.
Refer first to what is shown in FIG. A circuit module (30) and a correction mechanism (not shown in the figure) are provided in the shell (10) of the memory card, and a slide cover (20) is covered on the outside thereof.

  The shell (10) has a planar shape and has a first end (101) and an opposing second end (102), and a second / second shell body (13) / (14) combined in opposition. The outer surface of the first shell body (13) is the first surface, and the outer surface of the second shell body (14) is the second surface. Among these, the first surface has a plurality of grooves (131) formed at the edge adjacent to the first end (101), and the second surface has the communication interface port (12) on the second end (102). In this embodiment, the communication interface port (12) is composed of a plurality of conductive contacts (120), and each conductive contact (120) is electrically connected to the circuit module (30). Has been.

  The circuit module (30) is provided in the shell (10), a memory and related circuits are provided on a circuit board, and a plurality of metal contacts are formed at one end, and each metal contact ( (Not shown) constitutes the standard interface port (11) by being arranged corresponding to the inside of each groove (131) on the first shell body (13) of the shell (10). .

  The correction mechanism is provided in the shell (10) and disposed on the second end (102), and corresponds to the communication interface port (12) thereabove. The correction mechanism has an opening (141) at a position adjacent to the second end (102) of the second shell body (14), and a support (15) is provided in the opening (141). One or more springs (16) are provided below the support (15).

  The size of the support (15) coincides with the opening (141) so as to penetrate between the openings (141), and the periphery of the lower edge of the support (15) extends outward and is continuous. Since the stopper edge (150) is formed, and the stopper edge (150) is larger than the opening (141), the support (15) is regulated by the stopper edge (150) to the opening (141), It does not completely detach from the shell (10). Furthermore, the surface on the support (15) serves to form the conductive contact (120) as a communication interface port (12).

  Further, the spring (16) is supported between the support (15) and the inner bottom surface of the shell (10), and the support (15) is moved outside the second surface by the pushing biasing force of the spring (16). This is because the conductive contact (120) on it is also pushed up to an appropriate height (as shown in FIG. 4), so that the memory card shell (10) is connected to the communication interface port (12). ) Having the thickness of the second end (102) is supplemented to match the interface connector of the corresponding protocol, which means that a firm insertion and connection effect is obtained.

  The communication interface port (12) is expanded at one end of the memory card to comply with the USB interface standard, and the width of the second end (102) of the shell (10) is narrower than the first end (101). Therefore, when inserting and connecting to the reading / writing device using the standard interface port (11), the memory card is returned to the standard specification by the slide cover (20). The slide cover (20) is a casing made of metal or synthetic resin and having an inner width / inner height coincident with the shell (10) and having a bowl-shaped cross section. In order to be clamped, each of them extends inward in the horizontal direction to form a clamping part (21). The slide cover (20) has an open shape at one end and a closed shape at the other end. An opening groove (22) is formed on the closed end, and the position and shape of the opening groove (22). Is coincident with the second end (102) of the shell (10) so that the communication interface port (12) on the second end (102) can protrude through the opening groove (22).

  In order to cover the slide cover (20) as close as possible on the shell (10), a recess corresponding to the shape of the slide cover (20) is formed on the first / second surface, and the width and thickness are At the second end (102) of the shell (10).

  When the memory card is inserted and connected to the read / write device using the standard interface port (11), the slide cover (20) is pushed and moved to the second end (102) of the shell (10) as described above. Thus (as shown in FIG. 2), the width of the second end (102) is supplemented to be the same as that of the first end (101), so that the appearance completely matches the memory card. In the support body (15) for facilitating the passage of the slide cover (20) through the second end (102), the support body (15) is provided at the corner facing the pushing direction of the slide cover (20). A slope (151) is formed that allows the slide cover (20) to pass through the front edge of the slide cover (20) along the slope (151), and the support (15) is urged to slide the slide cover (20). Press into (as shown in FIG. 5). At this time, the spring (16) below the support (15) is in a compressed state, and when the slide cover (20) is returned and separated from the support (15), the support (15) is in contact with the spring (16). It is pushed upward by the return biasing force (as shown in FIG. 1).

  Reference is now made to FIGS. 6-9 showing a second preferred embodiment of the present invention. Its basic structure is substantially the same as that of the first preferred embodiment, but the difference is in the design change of the correction mechanism.

  The difference from the previous embodiment is that in this embodiment, the conductive contact (120) of the communication interface port (12) is formed directly on the first surface of the shell (10), and the correction mechanism is An opening (141) is formed at a position adjacent to the second end (102) in the second shell body (14), and a push-up support (17) is provided in the opening (141). One or more springs (16) are provided below the push-up support (17).

  The size of the push-up support (17) coincides with the opening (141) so that the push-up support (17) can protrude through the openings (141), and the periphery of the lower edge of the push-up support (17) is outside. Since the stopper edge (170) is larger than the opening (141), the push-up support (17) is opened by the stopper edge (170). 141) and does not completely detach from the shell (10). Further, when the slide cover (20) is pushed to the second end (102) at the corner facing the pushing direction of the slide cover (20), the push-up support (17) 17) A slope (171) for facilitating passage is formed.

  Further, the spring (16) is supported between the push-up support (17) and the inner upper surface of the shell (10). 2 that protrudes out of the surface, the conductive contact (120) above it is also pushed up to the appropriate height (as shown in FIG. 8), so that the memory card shell (10) communicates. The thickness of the second end (102) having the interface port (12) is supplemented, which is consistent with the interface connector of the corresponding protocol, meaning that a firm insertion effect is obtained.

  Similar to the previous embodiment, when the slide cover (20) is pushed to the second end (102) of the shell (10), the width of the second end (102) is the same as the first end (101). Alternatively, it is supplemented to approximate, and at the same time, the push-up support (17) is also pushed back into the shell (10) by the slide cover (20) (as shown in FIG. 9).

  Further, please refer to FIGS. 10 to 13 showing a third preferred embodiment according to the present invention. Its basic structure is substantially the same as that of the first preferred embodiment, but the difference is in the design change of the correction mechanism.

  In this embodiment, a plurality of elongated through grooves (142) are formed on the second shell body (14) adjacent to the second end of the shell (10), and each through groove (142) is formed. Each of the metal pieces (121) is provided therein to form a conductive contact (120) of the communication interface port (12). The metal pieces are generally arcuate and both end portions thereof are through-grooves. It is located below (142) and is in contact with the edge of the through groove (142) to be regulated, and the projecting portion of the intermediate part is exposed from the through groove (142). The correction mechanism is composed of a biasing plate (122) on at least one end of each metal piece (121). In this embodiment, the biasing plate (122) has a U-shape, The arm is pushed up and supported between the opposed inner bottom surfaces of the shell (10) and is electrically connected to the circuit module (30). The urging plate (122) gives the metal piece (121) an urging force that expands and contracts in the through groove (142), and each metal piece (121) is outside the through groove (142) in a normal state. And the thickness of the communication interface port (12) that is insufficient is compensated by being positioned at an appropriate height.

  The metal piece (121) in the through groove (142) has an arcuate shape, and one end of the slide cover (20) facing the pushing direction forms a slope, so that the slide cover (20) can easily pass through. When the slide cover (20) is positioned above each metal piece (121), the metal piece (121) is simultaneously pushed back into the shell (10), and the biasing plate (122) at one end is also At the same time, they are compressed (as shown in FIG. 13).

  Reference is also made to FIGS. 14-17 which show a fourth preferred embodiment of the present invention. Its structure is quite close to the third preferred embodiment, but the difference is in the change in the design of the correction mechanism.

The metal piece is generally arcuate and has both ends thereof. Is positioned below the through-groove (142), is in contact with the edge of the through-groove (142), and is regulated, and the protruding portion at the middle is exposed from the through-groove (142).

  The correction mechanism is constituted by a spring (16) provided below each metal piece (121), and each metal piece (121) is further connected to a circuit module (in the figure, via a spring (16)). (Not shown). The spring (16) is supported by being pushed up between the metal piece (121) and the inner bottom surface of the shell (10), so that the metal piece (121) has a biasing force to expand and contract in the through groove (142). In the normal state, each metal piece (121) is pushed up and supported by the spring (16) and is located outside the through groove (142), and at the appropriate height, similarly. The communication interface port (12) is made up of an insufficient thickness.

  The metal piece (121) in the through groove (142) has an arcuate shape, and one end of the slide cover (20) facing the pushing direction forms a slope, so that the slide cover (20) passes through. When the slide cover (20) is pushed up above the metal pieces (121), the metal pieces (121) are simultaneously pushed back into the shell (10). At this time, the metal pieces (121) The lower spring (16) is in a compressed state (as shown in FIG. 17).

As can be understood from the above, the present invention automatically corrects the thickness of the memory card at the position of the communication interface port by providing a thickness correction mechanism at a position corresponding to the communication interface port in the memory card.
