  • the bottom plate 55e for fixing is formed at the end portion of the column 55c of each half 55H, on the other hand, a rectangular concavity 51e a little larger than said bottom plate 55e is provided on the bottom wall 51b of the groove 51, and more preferably, the depth of said concavity 51e is determined to be equal or more than the thickness of the bottom plate 55e.
  • the bottom plate 55e is fixed under the modular-jack 9, being fitted in the concavity 51e, and each half 55H is fixed to the bottom wall 51b of the groove 51.
  • the same effects as the first embodiment is obtained, and particularly, since each half 55H is accommodated in each transverse slot 52 perpendicular to the inserting groove 51 for the modular-jack 9, the thickness of said securing member 55 depends upon only the width of the transverse slot 52, and can be determined in no relation to the thickness of PC card 53. Therefore, it becomes to be possible to design the thickness of the securing member 55 to be greater than that of the connector in the fourth embodiment.
  • a plurality of modular-jack connectors with same function are provided at a rear end portion of a PC card, and at least one connector is provided on reverse side to the others, with regard to the obverse and reverse of the PC card.
  • a couple of modular-jack connectors 60 are provided on reverse side each other, with regard to the obverse and reverse of the PC card.
  • the same connectors 60 for a modular-jack as shown in the first embodiment are provided at the end portion of the PC card 63, however, the connectors are not to be limited to that type, and, another type of modular-jack connectors may be provided. Also, different types of modular-jack connectors may be provided on the obverse and reverse side of the PC card.
  • a cavity 74 is formed at an end portion of a PC card 73, and in said cavity 74, a connector unit 79 being fabricated separately from the card body 73 is contained drawably to rear side.
  • Said connector unit 79 is constructed, by forming a inserting groove 71 for a modular-jack in the plate-like base plate 78, and mounting the securing member 75 for securing modular-jack to said groove 71. Then, the connector unit 79 become to be available to use, by drawing the base plate 78 from the cavity 74.
  • securing member the same one as described in the fourth embodiment is shown in the Fig.24, however, another type of securing member may be provided alternatively.
  • a pair of rod-like slide guides 77 guided through the guide grooves 74g formed on the cavity side walls are provided, and stopper 77a for preventing from dropping off is formed at an end portion of each slide guide 77.
  • the connector unit 79 is designed so that its end face protrudes a little from the rear end face 73r of PC card 73, in the contained condition in the cavity 74.
  • the connector electrode (not shown) of the modular-jack connector 70 can be protected effectively, because the modular-jack connector 70 is provided on the connector unit 79 being formed as a separated component from the card body 73 and the connector unit 79 is contained in the cavity 74 provided at the end portion of the card body 73 when the modular-jack is not connected thereto. Also, when the modular-jack is not connected, the appearance of said end portion of the PC card 73 is improved.
  • a pair of holders 86 for holding the connector unit 89 are provided at the end portion of each slide guide 87 which can slide along the guide groove 84g on each side wall of the cavity 84, and the base plate 88 of the connector unit 89 is supported rotatablly by the pin 86p mounted to the holder 86.
  • the base plate 88 can be rotate continuously within 180 degrees at maximum around said pin 86p, and the angle of the connector unit 89 to the PC card 83 can be changed properly in accordance with the circumferential condition.
  • a desired one may be provided in the groove 81 formed on the connector unit 89.
  • drawer type of connector unit 79,89 shown in the seventh or the eighth embodiment to the rear end portion of the PC card, as shown in the sixth embodiment, and at least one may be provided on the reverse side to the others, with regard to the obverse and reverse side of the PC card.
  • a modular-jack connector allowing a modular-jack to connect with a plate member directly and being convenient to use is provided.
  • a groove 11 for inserting the modular-jack thereinto is provided at an end portion of a PC card 1, the groove is elongated from an end face of the end portion to inner side of the PC card 1 in a direction along the card plane, and opens on one side in a thickness direction of the PC card 1.
  • connector electrodes 12 being able to contact with an electrode of the modular-jack is provided on an inside wall 11b of the groove 11.
  • the modular-jack connector has a securing member 15 for securing the modular-jack, being formed as a separated part from the PC card 1, and a support means 11h,15b which supports the securing member changeably between an accommodated position in the direction along the plane of the PC card 1 and a securing position to secure the modular-jack.
