Description

  The present invention relates to a substrate removal structure, and more particularly to a PCI (Peripheral Component Interconnect) card removal structure.

  In recent years, PCI cards mounted on electronic devices are often mounted with high density components. When replacing this PCI card, the PCI card already mounted is pulled out and a necessary PCI card is inserted. At this time, if the components are mounted at a high density on the already mounted PCI card, it is difficult to pick up the PCI card at the time of removal. In addition, parts may be damaged in an attempt to force picking.

  FIG. 5 is a diagram showing a board removal structure of a related PCI card. In FIG. 5, the PCI card 103 is vertically connected to the connector 109 of the motherboard 104. The PCI card 103 is connected to a bracket 105 with a screw 110, and the bracket 105 is fixed to a housing 108 of the electronic device with a screw 106. From the bracket 105, an interface terminal (not shown) of the electronic device is installed outward from the casing 108 of the electronic device. Here, the bracket 105 is fixed to the housing 108 of the electronic device with a screw 106 without a gap, and there is no space for gripping the bracket 105 even if the screw 106 is removed.

  In response to such a problem, a technique for removing a PCI card has been developed.

  For example, in Patent Document 1, in order to easily and reliably mount / remove a PCI card using the lever principle, the position of the fulcrum is separated from the PCI card, and the PCI card can be moved vertically up and down. Mechanism technology is disclosed.

Patent Document 2 discloses a technology of a circuit board mounting structure in which a circuit board card such as a PCI card can be smoothly inserted and removed from the front surface or the back surface of an information processing apparatus.
That is, a circuit board mounting structure in which an interface part of a circuit board can be inserted into and removed from a connector part of the apparatus in a direction different from the direction in which the circuit board is attached to or detached from the apparatus, and the operation part that rotates by receiving a force from an operator And is fixed to the circuit board so that it can be rotated in the direction opposite to the direction in which the operation unit rotates, and the force received by the operation unit is converted into a force in a direction different from the attaching / detaching direction, and the circuit board is moved in that direction.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram showing a substrate removal structure according to the first embodiment of the present invention. The substrate removal structure in this embodiment will be described with reference to FIG.

  In FIG. 1, a PCI card 3 as a substrate has a card edge 11 and is connected vertically to a connector 9 on the motherboard 4. The connector 9 is a connector having a structure for inserting an edge terminal of the board.

  The PCI card 3 is connected to the bracket 5 with screws 10 as fastening means, and the bracket 5 is fixed to the housing 8 of the electronic device with screws 6. From the bracket 5, an interface terminal (not shown) of the electronic device is installed outward from the housing 8 of the electronic device. The bracket 5 and the housing 8 of the electronic device are fixed together with screws 6 with the stopper 2 placed on top as a restraining portion. The stopper 2 is connected to the lever 1 with the rotating shaft 7 as a common axis. Further, instead of screws, fastening means such as bolts and nuts or push rivets may be used.

  2 and 3 are views showing the details of the substrate removal structure in the first embodiment of the present invention. The details of the substrate removal structure in this embodiment will be described with reference to FIGS. The same parts as those in FIG. 1 are given the same numbers.

  The end portion of the stopper 2 includes a rotating portion 26 at a portion wound in a cylindrical shape that passes through the rotating shaft 7. In addition, a hole 25 through which the screw 6 is passed is formed on the surface of the stopper 2 that contacts the bracket 5.

  The lever 1 is substantially L-shaped, and includes a rotating portion 15 of a cylindrical portion that passes through the rotation shaft 7 at the corner portion of the L-shape. The cylindrical rotating part 15 is divided into two parts in the axial direction, and the stopper rotating part 26 at the portion wound in the cylindrical shape of the stopper 2 is fitted therein. The lever 1 and the stopper 2 are independently rotatable with the rotation shaft 7 as a common axis. Further, both end portions of the rotating shaft 7 are bent and connected to the housing 8.

  When the stopper 2 is holding the bracket 5 from above and the screw 6 is removed, the stopper 2 can rotate upward independently of the lever 1 with the rotating shaft 7 as a fulcrum. The stopper 2 has an abutting surface 27 that is a surface bent in a direction substantially perpendicular to the surface to which the screw 6 is attached, and has a shape that abuts against the lever 1 when rotated upward about the rotating shaft 7. ing.

  The operation of the substrate removal structure in this embodiment will be described with reference to FIG.

  When the screw 6 is removed and the stopper 2 is lifted, the stopper 2 rotates in the direction of the lever 1 with the rotating shaft 7 as a fulcrum. When the corner of the abutment surface 27 of the stopper 2 abuts against the lever 1, the lever 1 rotates about the rotation shaft 7, and the push-up portion 16 on one side of the L-shaped lever 1 is the lever receiving portion of the bracket 5. Push 51 up from below.

  The lever 1 lifts the bracket 5 away from the housing 8 of the electronic device, creating a gap. As a result, the bracket 5 can be picked, so that the PCI card 3 can be easily pulled up.

  As described above, with the simple and compact structure, the PCI card 3 can be easily removed in conjunction with the release of the bracket presser. Whereas the extraction structures of Patent Documents 1 and 2 are about the same length as the width of the substrate, the extraction structure of the present embodiment fits only around the lever receiving portion 51 of the bracket 5 and is very compact. .

(Second Embodiment)
FIG. 4 is a diagram showing details of the substrate removal structure in the second embodiment of the present invention. The details of the substrate removal structure in the present embodiment will be described with reference to FIG. The same parts as those in FIG. In FIG. 4, a retaining screw 20 is used instead of the screw 6 of FIG. 1, and a stopper 22 is used instead of the stopper 2.

  The retaining screw 20 has a structure in which an outer cylindrical portion is fixed to the stopper 22, and the screw portion 21 in the cylindrical portion does not come off from the cylindrical portion even if it is detached from the bracket 5.

  Therefore, when the screw portion 21 of the retaining screw 20 is removed and the stopper 22 is lifted, the stopper 22 rotates in the direction of the lever 1 with the rotating shaft 7 as a fulcrum. When the stopper 22 hits the lever 1, the lever 1 rotates about the rotation shaft 7, and one side of the lever 1 pushes up the bracket 5 from below.

  The lever 1 lifts the bracket 5 away from the housing 8 of the electronic device, creating a gap. Thereby, since the bracket 5 can be pinched, the PCI card 3 can be pulled up.

  As described above, with the simple structure, it is possible to easily remove the PCI card 3 substrate in conjunction with the release of the bracket press, and to remove the PCI card 3 substrate during operation. However, it is possible to eliminate the possibility of dropping the screw in the energizing portion.

  As described above, according to the present embodiment, it is possible to easily remove the PCI card board in conjunction with the release of the bracket press with a simple structure.

  In addition, this invention is not limited to the above-mentioned embodiment, It can implement in various changes and deformation | transformation in the range which does not deviate from the summary of this invention. For example, the present invention is not limited to a PCI card but can be applied to other types of substrates.

  INDUSTRIAL APPLICABILITY The present invention can be used for a structure for removing a substrate connected to a card edge connector.
