It will be noted that a rectangular hole 13 (shown in dotted lines on Figure 2) is provided in the lid portion 1 of the PC card enclosure. This hole 13 provides for the insertion, and removal, of S.I.M. cards into, and out of, the card holding device 4.
  • the card holding device 4 comprises a card insert region 6 and a card holding region 7, both regions being integrally formed together from sheet metal material.
  • the card insert region 6 comprises a so-called "ramp" 8 which is essentially a sloping metal surface.
  • the card holding region 7 comprises an apertured surface 9, 11, defining an aperture 15.
  • Upwardly-projecting alignment members 12 are provided along the edges of the surface 9, 11 the alignment members being bent at their upper regions to form attachment surfaces 10. Although two alignment members 12 are shown in Figure 2, it will be appreciated that a single alignment member is sufficient to hold a S.I.M. card in position.
  • the card holding device 4 is attached to the inner lid surface 2 so that ramp region 8 of the card holding device is located directly beneath the hole 13.
  • the card is placed in the hole 13
  • the apertured region 15 is dimensioned so as to expose the active area of any inserted S.I.M. card to a S.I.M. card connector located directly beneath. Accordingly, it will be appreciated that alignment of the S.I.M. card within the holding region 7 must be accurate to ensure that a correct connection is achieved. This is achieved by the provision of the upwardly-projecting alignment members 12, which prevent lateral movement of the S.I.M. card when in position.

  • alignment edges are provided along both sides of the ramp 8, their edges enabling the S.I.M. card to be slidably moved up and down the ramp, without moving from side to side.

  • this may be achieved by cutting the hole 13 in the lid portion 1 so that the edges may be folded-down to provide any necessary alignment along the edges of the ramp 8.
  • the dimensions of the holding region 7 ensure that, when the S.I.M. card is secured in position within the card holding device 4, a portion of the S.I.M. card will remain within the card insert region 6, i.e. on the lower part of the ramp 8. This allows for easy removal of the S.I.M. card by use of a finger to press on the upper surface of the S.I.M. card and withdrawing it into the card insert region 6, and will not require the use of special tools etc. Of course, should the S.I.M. card become stuck for some reason, it may be removed using a simple tool such as a paper clip, access being gained via a small hole (not shown) in the lid portion 1.
  • the above-described two-piece holding device may be attached to the inner lid surface 2 by soldering, welding, or any suitable adhesive.
  • the card holding device 4 may be formed as part of the actual lid portion 1.
  • the rectangular hole 13 is formed by cutting the lid portion along three sides, and bending down the resulting "tongue". This tongue is thereafter shaped to form the card holding device 4 .
  • no holes or gaps should be visible through the lid portion 1.
  • the card holding device may be formed by cutting and pressing (or otherwise forming) part of the lid portion 1 down to form the features of this device. In this case, no additional formed part is required, and only one edge needs to be cut.
  • the dimensions of the card holding device 4, whichever embodiment is used, should be such so as to ensure that there is sufficient room beneath to avoid touching components on the PC card printed circuit board.
  • the underside of the lid portion 1 in the region of the S.I.M. card connector may be covered with an insulating material, such as a label, to ensure that the contacts of the S.I.M. connector or the S.I.M. card do not short, if they happen to touch the casing.
  • the ramp 8 may be modified to enhance the retention of the S.I.M. card when inserted in the card holding device 4. This may comprise a small flexible member, located in the middle of the ramp 8, which member is pushed down by the S.I.M. card during insertion, and then springs up behind the S.I.M. card when it is fully inserted. Removal is achieved by pushing the flexible member down.
  • the card holding device described above provides for design flexibility, in that it can be positioned on almost any part of the PC card lid portion 1. Accordingly, if the circuitry of the PC card is redesigned, with the S.I.M. card connector being positioned in a different area of the board, the card holding device may be moved accordingly. In the case of the first described embodiment, this is achieved by simply repositioning the hole in the design of new lid portions, and attaching the card holding device 4 beneath it, or, in the case of the second or third embodiments, cutting the tongue or cutting and pressing in the new location.
  • a side-sectional view of the card holding device 4 shows the sloping arrangement of the ramp 8 and the means by which an inserted S.I.M. Card (not shown) can be secured between the upper surface of the card insert region 6 and the card holding region 7.
  • the device could have a recessed surface (see Figure 4 which shows a second embodiment of card holding device having a recessed region 8a through which the S.I.M. card can be inserted, prior to being slid into position).
  • the device could also be modified to accommodate the newly-proposed S.I.M. card which has even smaller dimensions than those of the smaller size mentioned above.
  • the device itself could be made of any suitable material such as a plastics material. It would also be possible to replace the alignment edges 12 by parts of the casing of the PC card, parts of the casing of the S.I.M. card holding device, or even components of the PC card.
  • FIG. 5 to 7 A third embodiment of the present invention is shown in Figures 5 to 7. This embodiment is similar to that of Figures 1 to 3, so like reference numerals will be used for like parts, and only the modifications will be described in detail.
  • the card holding region includes a separate card guide member 17.
  • the guide member 17 comprises a generally U-shaped member.
  • the card guide member 17 is fixedly located (e.g. by solder or screws) onto a printed circuit board 19 which forms part of a communications device and is positioned over a S.I.M. card connector 21 with an open end 17a of the guide member being aligned to the card insert region 6.
  • the card guide member 17 is dimensioned so as to receive an inserted S.I.M. card 23 within the U-shaped body, and is arranged such that the card is positioned just below the top inner surface of the U-shaped body. In this way, the electrical contacts (not shown) of the S.I.M. card 23 remain secured against contacts 22 of the S.I.M. card connector 21, without requiring the inner lid surface 2 of the lid portion to maintain the contact engagement.
  • the tolerances involved in producing the lid portion in such a way that the S.I.M. card 23 is maintained in correct engagement with the S.I.M. card connector 21, can make the lid difficult and/or expensive to produce. Further, the lid portion may become damaged or deformed in normal use, and so, without the card guide member 17, there is a possibility that the electrical connection between the S.I.M. card 23 and the S.I.M. card connector 21 may be disrupted.
  • the card insert region 6 of the S.I.M. card holding device 4' is shown from beneath the inner lid surface 2. It will be seen that the card insert region 6 is the same as that shown in Figure 2. However, in this case, the card holding region is formed by the combination of the planar surface 27 at the end of the ramp 8, and the card guide member 17 (not shown in Figure 7) which forms a card holding member.
  • the S.I.M. card guide member 17 may be formed from any rigid material, e.g. a metal or plastics material.
  • the internal dimensions of the U-shaped body should be such that its width corresponds closely with the width of the S.I.M. card 23, so as to prevent or minimise lateral movement.
  • alignment tabs 25 may be included at the side-portions of the generally U-shaped body.
  • a further tab could also be included at the upper portion of the generally U-shaped body to ensure that the S.I.M. card 23 enters the body just beneath the upper inner surface.
  • the card holding device described above has further advantages over prior art devices, in that the area occupied by the holding device within a PC card enclosure is reduced. Alternative devices may not maintain good continuity of electromagnetic screening, which can cause problems in meeting electromagnetic compatibility (EMC) performance requirements.
  • EMC electromagnetic compatibility
  • the card holding device described above provides good EMC screening, is robust and is less fragile than prior art devices.
