BACKGROUND OF THE INVENTION The present invention relates to an adapter capable of expanding a variation on an electronic device that can use a memory card by mounting a memory card, especially a small memory card such as RS-MMC.

Commercially available memory cards include ATA (PC) cards, smart media cards, CF cards, and MMC (registered trademark). Meanwhile, RS (Reduced Size) -MMC (registered trademark), which has the same thickness as MMC but is approximately half the width and internal depth (length), has recently been developed. The RS-MMC has the same specifications as the MMC, and can be used as an alternative to the MMC, and can be used for electronic devices such as computers and mobile phones.

However, RS-MMC is compact and cannot be used for computers or external drivers that can be used with other memory cards such as MMC. Currently, RS-MMC can only be used for dedicated computers or external drivers that are compatible with RS-MMC. It is supposed to be. For this reason, in a small memory card such as RS-MMC, there is a problem that the range of electronic devices that can be used is limited.

The present invention has been made in view of the above problems, and by mounting a small memory card such as RS-MMC, the present invention can be used for an electronic device corresponding to a memory card of a normal size such as MMC, thereby enabling the use of a small memory card. It is an object of the present invention to provide an adapter for a memory card which can extend the range.

In order to achieve the above object, the adapter for a memory card of the present invention according to claim 1 comprises a frame bracket for mounting the memory card so that the memory card is detachable by inserting an end portion of the memory card, and a resin molded body inserted into the frame bracket. At the same time as the core, the overall thickness is almost the same as that of the memory card. The frame brackets are formed in pairs in a substantially U shape at both ends of the mounting side of the memory card. A hook part installed between the holding part holding both sides of the card, and a pair of holding parts, the hook part being coupled to the end of the memory card by a spring force to prevent the memory card from falling off; It is provided with a caulking protrusion for fixing the core by caulking to the core It features.

In the invention of claim 1, by inserting the core into the frame bracket and caulking the caulking projection, the core is provided in the frame bracket to form an adapter for the memory card. In this adapter, by inserting the memory card into the frame bracket, the holding portion holds both sides of the memory card, while the hook portion is engaged by the spring force to the memory card to prevent its detachment, thereby mounting the memory card to the adapter.

In the attached state of the memory card, the combined dimensions of the memory card and the adapter are the same as those of the conventional memory card. The thickness of the adapter is almost equal to that of the memory card. As a result, when the memory card is mounted in the adapter, the size becomes the same as the memory card of a normal size, so that the memory card can be used in an electronic device for a memory card of a normal size, and the usable range of the small memory card can be expanded. have.

The invention of claim 2 is the adapter for a memory card according to claim 1, wherein the pair of holding portions are formed in a substantially U-shape and are provided with a spring force for elastically holding the memory card, and at least one holding.

In the invention of claim 3, since the opening preventing piece is engaged with the core, the opening of the holding portion is suppressed, so that the frame bracket maintains a constant thickness and the overall thickness of the adapter does not increase. For this reason, it can be reliably attached to an electronic device. In addition, since the memory card can be reliably held by the holding portion, it is possible to prevent the memory card from falling off. Furthermore, even when the memory card is frequently attached and detached, the holding portion maintains an approximately U-shape, so that durability can be provided.

The invention of claim 4 is the adapter for a memory card according to any one of claims 1 to 3, characterized in that the insertion side end surface of the memory card is recessed obliquely along the insertion direction in the pair of holding portions.

By digging the holding portion at an angle in this manner, the resistance becomes large when the memory card is correctly inserted, whereas the resistance increases when the memory card is inserted in the opposite direction. For this reason, it is possible to prevent it by the feeling at the time of inserting the reverse mounting of a memory card.

The invention of claim 5 is the adapter for a memory card according to any one of claims 1 to 4, wherein at least one holding portion of the pair of holding portions is engaged with the memory card to rotate the relative rotation of the memory card relative to the frame bracket. A notch portion serving as a center is formed.

In the invention of claim 5, the memory card can be attached to the adapter by relatively rotating the memory card around the notch, so that the memory card can be easily mounted.

In the present invention, the locking projection corresponding to the notch portion is formed at one end of the memory card, whereby the locking projection and the notch portion can be locked to form the rotation center described above. As a result, the relative rotation of the memory card can be performed stably, so that the memory card can be mounted more simply. Furthermore, since the directionality at the time of mounting is provided by forming the locking projection at one end with respect to the memory card, reverse mounting of the memory card can be prevented.

In the invention of claim 7, since the hook portion is restricted from being carried away from the core, the hook portion does not fall from the core. As a result, the posture of the hook portion with respect to the memory card is always constant, so that the memory card can be reliably engaged by the hook portion.

Invention of Claim 8 is formed by forming an insulating film in the whole outer surface of a frame bracket.

In the invention of claim 8, even if the adapter is incorrectly attached to the connector, a short circuit between the contacts of the connector can be completely prevented by the insulating coating formed on the entire outer surface of the frame bracket.

According to a ninth aspect of the invention, an insulating coating is formed by partially forming the outer surface of the frame bracket.

In the invention of claim 9, even if the adapter is incorrectly attached to the connector, the short circuit between the contacts of the connector can be sufficiently prevented by the insulating coating formed only on the necessary portion around the outer surface of the frame bracket.

Invention of Claim 10 is formed by forming an insulating film by thermoplastic or thermosetting resins, such as an acrylic resin, a polyethylene resin, a polyimide resin, a polyamide resin, a fluororesin, an epoxy resin, and a polyester resin.

In the invention of claim 10, since various thermoplastic or thermosetting resins are used as the insulating coating, insulation can be maintained for a long time without reducing the mechanical strength to the frame bracket.

The invention of claim 11 is the adapter for a memory card according to any one of claims 1 to 10, wherein the memory card is an RS-MMC.

In the invention of claim 11, the small RS-MMC can be used in the same manner as the MMC of a normal size.

EMBODIMENT OF THE INVENTION Hereinafter, if one Embodiment of this invention is described with reference to FIGS. 1-29, the adapter 1 of this embodiment is provided with the frame bracket 2 and the core 3. As shown in FIG.

On the other hand, before describing the adapter 1 of the present embodiment, the memory card 4 attached to the adapter 1 will be described. The memory card 4 is a small memory card whose length is shorter than that of a normal sized memory card. In this embodiment, RS-MMC (registered trademark) is used. In the compact memory card 4 made of RS-MMC, as shown in FIGS. 16 to 18, a pair of held portions 41 and 42 having a thin thickness at both ends in the width direction of the main body 40. ) Are formed on both sides. The held portions 41 and 42 are held by the holding portions 21 and 22 of the adapter 1. In addition, between the pair of held portions 41 and 42, a quadrangular engaging groove 43 which is lowered in a step shape is formed. Coupling groove 43 is formed on the lower surface of the main body 40, the hook portion 23 of the adapter 1 is engaged with the coupling groove 43. These to-be-held parts 41 and 42 and the engaging groove 43 are formed in the edge part of the adapter 1 side in the main body 40. As shown in FIG.

Furthermore, by coating a colored material of various colors on the surface of the memory card 4, it is possible to identify the memory card 4 by color, thereby improving convenience and at the same time being carried out during the coating process. By the heat treatment of about 200-300 degreeC, the frame bracket 2 becomes hard and mechanical strength can be improved. An increase of about 5% was observed in the measurement.

The frame bracket 2 in the adapter 1 is provided with a memory card 4, and is formed entirely of metal such as stainless steel. And if the adapter 1 is incorrectly attached to the connector 50 as shown in FIGS. 30 and 31 on the outer surface of the frame bracket 2 formed entirely of this metal, the connector ( The insulating film 60 is formed so as not to short-circuit between the contacts 51 of 50). This insulating film 60 is made of a thermoplastic or thermosetting resin such as an acrylic resin, a polyethylene resin, a polyimide resin, a polyamide resin, a fluorine resin, an epoxy resin, a polyester resin, or the like. In addition, you may employ | adopt any means, such as coating or coating, in formation of the insulating film 60 with respect to the frame bracket 2. Moreover, although the whole outer surface of the frame bracket 2 is preferable in the range which forms this insulating film 60, it is not necessarily limited to this, For example, as shown in FIG. 28 and FIG. 29, the frame bracket 2 It may be formed only on the outer circumference (about 2 to 4 mm). This is because the function of short circuit prevention is fully exhibited also by this.

Moreover, the frame bracket 2 has a substantially flat plate-shaped support plate 20 and a pair of left and right holding portions formed with respect to the support plate 20 as shown in FIGS. 1, 2 and 8. 21, 22, the hook part 23, and the caulking protrusion 24 are provided.

The holding parts 21 and 22 are formed in pairs by bending both left and right ends of the support plate part 20 on the mounting side of the memory card 4 in a substantially U shape. Each of the holding portions 21 and 22 is formed in a substantially U shape so that the openings face each other, and both ends of the memory card 4 are inserted into the holding portions 21 and 22, thereby holding the holding portions 21 and 22. 22 holds the to-be-held portions 41 and 42 at both ends of the memory card 4. This holding prevents the memory card 4 from being shifted in the left and right directions and in the vertical direction, so that the adapter 1 and the memory card 4 are less than shown in FIGS. 17 and 18. It is mounted in the same plane state without distance. In addition, by holding the both ends of the memory card 4 by the holding parts 21 and 22, the adapter 1 and the memory card 4 can be prevented from being bent to have a "u" shape. It is not twisted, and the detachment by a twist can be prevented.

The holding portions 21 and 22 are bent in a substantially U-shape so that spring forces are applied to the upper pieces 21a and 22a so that the upper pieces 21a and 22a are elastically attached to the memory card 4. Contact. By holding the inserted memory card 4 elastically by the holding portions 21 and 22, the memory card 4 can be reliably held.

On the other hand, the centering boss part 25 is formed in the lower piece 21b, 22b by the support plate part 20 side in the holding part 21, 22. As shown in FIG. The centering boss portion 25 is formed by partially raising the lower pieces 21b and 22b. Each of the centering bosses 25 inserts the memory card 4 into the holding portions 21 and 22 to thereby hold the held portions 41 and 42 and the main body portion 40 of the memory card 4. It contacts with the step part 45 which is a boundary part of. Since the centering of the memory card 4 is performed by this contact, the memory card 4 can be reliably mounted in the regular position with respect to the adapter 1. Moreover, what is necessary is just to form the centering boss part 25 in either of the holding parts 21 and 22 which are paired.

The opening prevention piece 26 is formed in the upper pieces 21a and 22a in the holding parts 21 and 22. As shown in FIG. The opening prevention piece 26 is formed by bending each upper piece 21a, 22a downward and extending in the direction of the core 3 in this bending state, as shown in FIGS. The opening preventing piece 26 is engaged with the core 3 by entering the slit 31 formed in the core 3. By this coupling, the opening preventing piece 26 prevents the upper pieces 21a and 22a from being deformed upward or curved upward. As a result, the holding portions 21 and 22 can be suppressed from being opened from the respective U-shape in the molded initial state. Therefore, since the frame bracket 2 maintains a constant thickness and the thickness of the whole adapter 1 does not increase, it can be reliably attached to an electronic device, and the memory card is carried out by the holding parts 21 and 22. FIG. (4) can be held firmly, and the fall can be prevented. In addition, even when the memory card 4 is frequently attached and detached, the holding portions 21 and 22 function to maintain a substantially U shape, so that durability can be provided.

Inclined surfaces 27 are formed on the upper pieces 21a and 22a of the paired holding portions 21 and 22, respectively (see Fig. 1). The inclined surface 27 is formed on the end surface of the insertion side of the memory card 4 in the upper pieces 21a and 22a of the holding portions 21 and 22, and the inside of the insertion direction of the memory card 4 is further inserted. It is formed by digging inwardly at an angle. By forming the inclined surface 27 in this way, the resistance becomes large when the memory card 4 is normally inserted, whereas the resistance increases when the memory card 4 is inserted in the opposite direction. For this reason, it can prevent by the feeling at the time of inserting the reverse mounting of the memory card 4. As shown in FIG. On the other hand, the lengths of the upper pieces 21a and 22a and the lower pieces 21b and 22b of the paired holding parts 21 and 22 are slightly different in the illustrated example, or approximately the same length along the short side. It may be formed.

The hook portion 23 is provided in the frame bracket 2 so as to be positioned between the pair of holding portions 21 and 22. The hook portion 23 is formed by bending an end portion of the support plate portion 20 in a substantially right angle in a downward direction. Like the holding portions 21 and 22, the hook portion 23 is formed on the mounting side of the memory card 4. It is formed in the frame fitting 2 so that it may become into the position slightly inward from the parts 21 and 22. FIG. The hook portion 23 is engaged with the engaging groove 43 of the memory card 4, and is fixed to prevent the memory card 4 from being detached from the adapter 1 by this engagement. On the other hand, by adjusting the height of the hook portion 23 can be coupled to the coupling groove 43 'provided on the opposite side to the coupling groove 43 of the memory card (4). This makes it possible to attach the memory card 4 to both the inside and the outside (see Figs. 19 to 21).

The hook part 23 is formed so that it may be provided in series with the support plate part 20, The extension part 20a with the hook part 23 in the support plate part 20 is shown in FIG.2 and FIG.8. As described above, the long straight slits 20b and 20b are formed in parallel. The spring force is applied to the extension formation part 20a by formation of these slit 20b, 20b. Therefore, the spring force is applied to the hook part 23 provided in connection with the extension formation part 20a. . Therefore, since the hook portion 23 is coupled to the memory card 4 together with the spring force, the hook portion 23 can be reliably engaged. In addition, as shown in FIG. 2, the letter 20c and the serration 20d of "PUSH" are engraved or printed near the extension formation part 20a. As a result, since the pressing position is displayed, the operability is improved and the anti-slip function is provided.

The caulking protrusion 24 is formed in the standing shape on both sides of the width direction of the support plate part 20, and it fixes the core 3 by caulking.

The core 3 consists of resin moldings, such as PBT resin, and is shape | molded so that it may become a substantially rectangular thin plate in planar view. Thus, by forming the core 3 by the resin molded object, weight reduction of the adapter 1 can be aimed at and handling property improves. In addition, the core 3 may be what coated or coated the coloring material to the molded object of metal die-casting (for example, aluminum, zinc, etc.). Although it becomes heavy when it is shape | molded in metal in this way, the strength can be raised significantly.

On the opposite surface to the frame bracket 2 in the core 3, an insertion portion 33 fitted to the holding portions 21 and 22 of the frame bracket 2 is formed by providing a recess in the upper surface. By inserting the insertion part 33 into the holding parts 21 and 22, the core 3 is attached to the frame fitting 2 in the state positioned in the left-right direction. In this case, since the spring force is applied to the holding parts 21 and 22 as mentioned above, when inserting the insertion part 33 into the holding parts 21 and 22, as shown in FIG. The upper pieces 21a and 22a of the 21 and 22 are elastically press-contacted with the insertion part 33. Thereby, the core 3 can be temporarily installed with respect to the frame bracket 2.

The core 3 is attached to the frame bracket 2 by sliding the upper surface of the support plate 20. In the state of being attached to the frame bracket 2, the upper surface 34 of the core 3 is It is in an exposed state. Since the exposed upper surface 34 can be held by hand and the memory card 4 can be mounted, the hand of the metal frame bracket can be prevented from being injured. In this case, the upper surface 34 of the core 3 may be subjected to texture processing, whereby unevenness due to sink marks of the resin at the time of molding becomes inconspicuous and the appearance is improved. At the same time, it is possible to prevent slipping when the frame fitting 2 is attached.

The slit 31 mentioned above is formed in the insertion part 33 side which is an edge part of the mounting side of the memory card 4 in the core 3. Moreover, the caulking accommodating part 32 corresponding to the caulking protrusion 24 is formed in the width direction on both sides. As shown in FIG. 15, the caulking receiving part 32 is formed so that the outer surface may become arch shape, and the caulking protrusion 24 of the frame bracket 2 will be cocked, and the caulking protrusion 24 and Combined. By this coupling, the core 3 can be fixed to the frame bracket 2. In this manner, in the fixing by caulking, unlike the fixing by indentation, a large fixing strength can be obtained, and there is no secular variation, and it can be stably fixed to the core 3 and the frame bracket 2. However, in addition to the caulking method, it may also be followed by a fixing method by an adhesive.

Moreover, the rib 35 is formed in the longitudinal direction in the lower surface of the core 3, as shown to FIG. 12, FIG. By so-called coring the core 3 in this manner, the strength is imparted and the amount of resin to be used can be reduced. Further, an elongated groove 36 is formed in the rear portion of the core 3 to facilitate the withdrawal from the electronic device. Although the long groove 36 is provided in the upper and lower surfaces in the illustrated example, it may be provided only in any one surface. In addition, since the long groove 36 can be operated without the original, the groove 36 is not essential.

In addition, the displacement control part is formed in the hook part 23 of the core 3 and the frame fitting 2. As shown in FIGS. 2 and 3, the displacement restricting portion is formed on the core 3 so as to correspond to the contact ear portion 28 and the contact ear portion 28 formed at both ends in the longitudinal direction of the hook portion 23. It is comprised by the part 37. In such a displacement restricting portion, when the core 3 is attached to the frame bracket 2, the pressing portion 37 abuts against the contact ear portion 28 from below and is pressed firmly. Because of this pressing, since the hook portion 23 and the extension forming portion 20a regulate the displacement (see FIG. 21) separated from the core 3, they do not fall off from the core 3. Thereby, since the posture of the hook portion 23 with respect to the memory card 4 is always constant, the hook portion 23 can be reliably coupled to the memory card 4.

8 to 15 show a process of manufacturing the adapter 1 by attaching the core 3 to the frame bracket 2.

As shown in FIG. 8, the core 3 is approached from the rear of the frame bracket 2, and as shown in FIGS. 9 and 10, the insertion portion 33 of the core 3 is moved to the frame bracket 2. Insert into the holding parts (21, 22) of the back. At this time, the caulking protrusion 24 stands up from the support plate 20.

11 shows a state in which the insertion part 33 is completely inserted into the holding parts 21 and 22. At this time, since the holding parts 21 and 22 have a spring force, the holding parts 21 and 22 can firmly support the insertion part 33. As a result, the core 3 and the frame bracket 2 are temporarily placed.

Fig. 15 shows a state in which caulking is performed with respect to the temporary installation state. The assembly in the temporary installation state is placed on the caulking die 5, and the caulking punch 6 is brought close to the caulking die 5 (state of FIG. 15A). An arched caulking recess 6a is formed in the caulking punch 6, and the caulking recess 6a touches the caulking protrusion 24 by access to the caulking die 5, and the projection 24 is provided. ) Is forcibly bent (states of Figs. 15B and 15C). Thus, the caulking protrusion 24 is caulked to the caulking receiving portion 32 of the core 3 so that the core 3 and the frame bracket 2 are firmly mounted, and FIGS. 13, 14, and 1, FIG. As shown in 2, the adapter 1 is manufactured. In the produced adapter 1, the overall thickness becomes almost the same as that of the memory card 4.

16 to 19 show a process of mounting the memory card 4 to the adapter 1 thus produced.

As shown in FIG. 16 and FIG. 19A, the adapter 1 and the memory card 4 are opposed to each other, and the held parts 41 and 42 of the memory card 4 are moved to the frame bracket 2. Is slowly inserted into the holding portions 21 and 22 of the apparatus. By this insertion, the rear end portion 46 of the memory card 4 abuts against the hook portion 23 of the frame bracket 2 (Fig. 19B), and pushes the hook portion 23 down. At this time, by forming the guide taper 46a at the rear end 46 of the mounting side of the memory card 4, the hook portion 23 slides the guide taper 46a, so that it can be smoothly pushed down. (FIGS. 19C and 19D). By this slide, when the hook portion 23 rides over the rear end 46 of the memory card 4, the hook portion 23 enters the engaging groove 43 of the memory card 4 by a spring force, It is engaged with the engaging groove 43 by the spring force (Fig. 19E). By this combination, the memory card 4 is attached to the adapter 1. In such mounting, the adapter 1 and the memory card 4 only need to be brought close to each other, so that the mounting can be performed simply.

In the mounting state of the memory card 4, the combined size of the memory card 4 and the adapter 1 is the same as that of a memory card of a normal size. In addition, as described above, the thickness of the adapter 1 is almost equal to the thickness of the memory card 4. For this reason, in the state where the memory card 4 is attached to the adapter 1, it becomes equal to the size of the memory card of a normal size. As a result, it can be used for electronic devices for mobile cards, mobile phones and the like of a normal size, so that the range in which a small memory card such as RS-MMC can be used can be expanded.

On the other hand, since the displacement in the half direction with the core 3 is restricted by the displacement control part which consists of the contact ear part 28 and the press part 37 of the core 3, the hook part 23 is hooked. The part 23 does not fall from the core 3. Thereby, the attitude | position of the hook part 23 with respect to the memory card 4 is not always made the same state as FIG. 21, and it can be reliably combined with the memory card 4. As shown in FIG.

20 shows an operation of removing the memory card 4 from the adapter 1. When removing, the hook 23 is pushed down to release the engagement with the engagement groove 43. In this release state, the memory card 4 can be removed by removing the memory card 4 and the adapter 1. Therefore, removal of the memory card 4 can also be performed simply.

In this embodiment, as shown in FIG. 1 and FIG. 2, the notch portion 29 is formed in the holding portion 21 or 22.
