Description

  The present invention relates to an electronic device, and more particularly to a card adapter with a terminal protection function.

The known multi-card adapter has multiple sets of terminals, and the terminals extend into the housing and can be applied to various standard cards by being positioned to correspond to the contact end of each standard memory card. is there.
However, since all the terminals of the known card adapter extend into the housing, when a card is inserted, a terminal that does not correspond to the card may be rubbed or the terminal may be deformed by impact. Therefore, the writing and reading of the card may be affected. In view of this problem, how to protect the terminal in the multi-card adapter industry is the most important issue to be solved.

The well-known terminal protection technology has a slide portion that can slide inside the card adapter as shown in US Pat. No. 6,641,413, and corresponds to the SD / MMC card of the card adapter by the terminal pressure control technology. By controlling the terminals, it is possible to prevent the terminals from colliding with each other when the MS card is inserted.
On the other hand, the technology that can protect the terminal inside the card adapter devised by the inventor not only can protect the terminal inside the card adapter, but the technology and structure are different from the well-known US patent proposal. .

A main object of the present invention is to provide a card adapter with a terminal protection function capable of protecting a terminal from deformation or damage due to an impact applied from another type of card.
Another object of the present invention is to provide a card adapter with a terminal protection function which has an effect of selecting a specific terminal in the card adapter and controlling it.

In order to achieve the above object, a card adapter with a terminal protection function according to the present invention includes a housing and a pressure control plate. The housing has an opening located at the front end and at least two sets of terminals disposed in the housing and extending into the housing. Of the terminals, the first set of terminals is positioned at the rear end of the housing, the second set of terminals is positioned at the bottom of the housing, and the body of the second terminal springs up elastically and contacts its end. Part is formed. The housing has rails along the vertical direction on both side walls, and has an installation portion on the bottom surface. The pressure control plate has guide portions mounted on two rails so that it can slide up and down at both ends, has at least one inclined surface at the front end, and has a plurality of perforations in its body. The body of the second set of terminals hits the bottom surface of the pressure plate upward, and the contact portion penetrates the hole from the bottom to the top and is exposed above the pressure plate.
Since the present invention selects a specific terminal by pressing the second set of terminals by lifting and lowering the pressure plate and controls it, the card may be impacted or deformed by a card with a different standard. And it is possible to prevent a problem that a short circuit occurs between terminals when a card having a different standard is inserted. Therefore, the effect of protecting the terminal can be achieved.

Hereinafter, the structure and characteristics of a card adapter with a terminal protection function according to an embodiment of the present invention will be described with reference to the drawings. First, the description of the drawings is as follows.

FIG. 8 is an exploded perspective view of a card adapter with a terminal protection function according to a second embodiment of the present invention.

As shown in FIGS. 1 to 4, the card adapter 10 with a terminal protection function according to the first embodiment of the present invention includes a housing and a pressure plate.
The housing 11 is composed of a base 12 and a cover plate 14, and the housing 11 is composed of an opening 16 positioned at the front end so as to be used for insertion of a card and a plurality of terminals, and is disposed on the base 12 and There are at least two sets of terminals 18 extending between the base 12 and the cover plate 14, and the first set of terminals 181 among the terminals 18 is based on an MS (Memory Stick) standard memory card. The second set of terminals 182 is positioned on the top surface of the base 12 so as to correspond to an XD (Extreme Digital) standard memory card. Further, the body of the second set of terminals 182 springs up elastically, and a contact portion 183 is formed at the end thereof. The second set of terminals 182 has a support portion 184 formed by bending the end of the contact portion 183, and the base 12 has rails 19 along the vertical direction on both side walls. The rail 19 is two parallel concave tubs and has an end point 191. The base 12 has an installation part 121 on the top surface.

  The pressure control plate 21 has guide portions 22 at both ends, and the guide portions 22 are divided into two protruding ear portions, and are mounted in the rail 19 so as to be slidable up and down. The front end of the pressure control plate 21 has at least one inclined surface 24, and the inclined surface 24 is formed to extend forward and downward from the front end of the pressure control plate 21. The body of the pressure control plate 21 has a plurality of perforations 26. The second set of terminals 182 can raise the pressure control plate 21 when the body portion and the support portion 184 face the bottom surface of the pressure control plate 21 upward. When the two guide portions 22 are positioned so as to abut against the two end points 191, the contact portion 183 penetrates the perforation 26 from the bottom to the top and is exposed above the pressure control plate 21. Further, when the pressure control plate 21 is lowered, it is located in the installation part 121.

As shown in FIG. 4, before inserting the card into the card adapter 10 with terminal protection function, the pressure control plate 21 is supported and raised by the force of the second set of terminals 182 jumping up, and is raised by the two end points 191. To stop.
As shown in FIG. 5, when the MS card 91 is inserted into the card adapter with terminal protection function 10, the front end of the MS card 91 hits the slope 24. When the MS card 91 is continuously advanced, the slope 24 is pressed downward, and the pressure control plate 21 descends along the two rails 19 to press the second set of terminals 182 downward. As shown in FIG. 6, when the MS card 91 is continuously advanced to the end in the housing 11 and brought into contact with the first set of terminals 181, the insertion operation is completed. At this time, the pressure control plate 21 is pressed from the MS card 91 and falls into the installation portion 121, and the contact portion 183 of the second set of terminals 182 is completely pressed into the installation portion 121 without contacting the MS card 91. As a result, in the process of inserting the MS card 91, the second set of terminals 182 is not contacted, so that a situation where a collision occurs, the terminals are broken, or a short circuit occurs between the terminals does not occur. found.

  The step of extracting the MS card 91 is reverse to the order of the above-described operations. When the MS card 91 is extracted and the state as shown in FIG. 5 is exhibited, the second set of terminals 182 is in a state of being suppressed. When the MS card 91 is continuously retracted and takes a state as shown in FIG. 5, the pressure control plate 21 is released and is raised by receiving an elastic action facing the second set of terminals 182. At this time, the bottom surface of the MS card 91 is completely separated from the second set of terminals 182, so that a situation of contacting or colliding with the second set of terminals 182 does not occur. As a result, in the process of extracting the MS card 91, it has been found that the terminal protection effect can be achieved because the situation that the second set of terminals 182 is not touched or collides does not occur.

As shown in FIG. 7, when the XD card 92 is inserted into the card adapter 10 with a terminal protection function, there is a gap below the XD card 92, so the slope 24 at the front end of the pressure plate 21 does not act, and the pressure plate 21 Therefore, the second set of terminals 182 directly contact the XD card 92 without being pressed downward.
As shown in FIG. 8, the card adapter 30 with a terminal protection function according to the second embodiment of the present invention is substantially the same as the first embodiment. The difference is that a plurality of guide tanks 48 are provided on the bottom surface of the pressure control plate 41, and the second set of terminals 382 are attached to these guides 48.

  Since the operation method of the second embodiment is the same as that of the first embodiment, a detailed description is omitted. Further, since the position of the second set of terminals 382 is limited by the guide tank 48 in the process of raising and lowering the pressure control plate 41, the contact portion 383 accurately controls the perforation 46 of the pressure control plate 41 in the process of operating the second set of terminals 382. Hold to aim. Therefore, it is possible to prevent the problem that the contact portion 383 does not aim at the perforation 46 and cannot be fitted in the process of raising the pressure control plate 41.

In summary, the advantages of the embodiments of the present invention are as follows.
First, the terminal can be protected. In the embodiment of the present invention, in the process of inserting the MS card 91, the terminal corresponding to the XD card 92 (that is, the second set of terminals) is pressed downward to prevent the MS card 91 from colliding with the first card. The two sets of terminals are protected without being shocked or deformed, and the reliability of the card adapter is ensured.
Second, selectively control the terminal. In the embodiment of the present invention, when the MS card 91 is inserted, the second set of terminals are suppressed, and when the XD card 92 is inserted, the second set of terminals are not pressed and contacted. Therefore, it is possible to achieve a protective effect by selecting a specific terminal and controlling it when inserting a specific card. In addition, when the MS card 91 of the metal housing is inserted, it is possible to prevent a problem that a short circuit occurs between the second set of terminals.
3. The operation stroke is short. The slide part mentioned in the above-mentioned United States patent proposal does not raise the SD card terminal unless it slides a predetermined distance, whereas in the embodiment of the present invention, it directly lowers the pressure control plate to control the terminal. The effect of selecting the terminal with is achieved. Comparing the two, the embodiment of the present invention has a short process of pressing the pressure plate downward, the structure is simple, and the precision is easy to control.
Since the description of the MS card 91 and the XD card 92 given in the embodiments of the present invention is only an example, the present invention cannot be limited to cards of the above standards. Also, when a structure similar to the present invention is applied to other types of cards, it should belong to the claims of the present invention.
