Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plug-in unit housing of an electronic device, and more particularly to a retaining structure for a plug-in unit housed in a plug-in unit housing.

[0002]

[Prior Art]

 FIG. 5 shows a conventional plug-in unit housing for electronic equipment, which has a mother board 1 and a pair of guide rails 2 and 3 projecting from the mother board 1, and a mother board 1 on which a connector jack 4 is provided. is set up. The pair of guide rails 2 and 3 are held by the frame 5 so as to face each other in parallel, and a guide groove 6 is formed in each of the guide rails 2 and 3. Each of the plurality of plug-in units 7 has a connector plug 8 at its tip and is guided by the guide groove 6 when inserted between the pair of guide rails 2 and 3. The connector plug 8 is connected to the connector jack 4 of the motherboard 1 by pushing the plug-in unit 7 when the insertion is completed.

In order to prevent the connector plug 8 of the plug-in unit 7 from coming off from the connector jack 4 of the motherboard 1 due to vibrations and shocks that occur during transportation and use of electronic equipment, a mechanism for preventing the plug-in unit 7 from coming off is provided in the housing. It is provided. The retaining mechanism is composed of a stopper member 10 attached to the frame 5 with screws 9. The stopper member 10 comes into contact with the end portion of the inserted plug-in unit 7, and the plug-in unit 7 comes out of the housing due to the vibration or shock during the transportation or use, that is, the withdrawal connector plug 8 The connector jack 4 is prevented from coming off.

[0004]

[Problems to be solved by the device]

 However, in the conventional plug-in unit housing of the electronic device described above, the stopper member 10 is detached from the frame 5 at each time of maintenance / inspection of the housed plug-in unit or expansion of the plug-in unit, and maintenance / inspection is performed. There was a problem that the workability was poor because it had to be reattached at the end of the expansion. Therefore, an object of the present invention is to provide a plug-in unit accommodating housing for an electronic device, which makes it possible to perform addition, maintenance, and inspection of the plug-in unit very easily.

[0005]

[Means for Solving the Problems]

 In order to achieve this object, the present invention is provided on a motherboard, a pair of guide rails that project substantially perpendicularly to the motherboard and are parallel to each other, and a plug-in unit is sandwiched between the guide rails. The plug-in unit is inserted between the pair of guide rails, and when the insertion is completed, a plug-in unit accommodating housing of an electronic device comprising a connector to be connected to the connector of the plug-in unit is provided. The protruding end of the guide rail is movable so as to be movable between a withdrawal position that engages with the inserted plug-in unit and prevents the plug-in unit from retreating from the guide rail, and a retracted position that allows the retreat. It is characterized by comprising a stopper member attached to the front of the. In this structure, the stopper member is provided with a crank-shaped through-hole and extends along the projecting end, and the stopper member is bent substantially at a right angle to engage with the plug-in unit. It is desirable that it is movably attached to the front of the projecting end by a screw that penetrates the through slot.

[0006]

[Action]

 When the stopper member is in the disengagement position, it engages the plug-in unit housed in the housing and prevents it from exiting to the outside, that is, performs the disengagement function of the plug-in unit and thereby the plug-in unit. Prevent the connector of the unit from coming off the connector of the motherboard. When inserting the plug-in unit into the housing for adding a plug-in unit, or when pulling out the plug-in unit from the housing for maintenance and inspection, move the stopper member from the stopper position to the retracted position. .. This allows the plug-in unit to be inserted into and withdrawn from between the pair of guide rails. In this way, by simply moving the stopper member between the stopper position and the retracted position, it is possible to switch between preventing the plug-in unit from moving out and permitting insertion / removal of the plug-in unit.

[0007]

【Example】

 An embodiment of a plug-in unit housing for an electronic device according to the present invention will be described below with reference to FIGS. 1 to 4, in which the same parts as those in FIG. 1 to 4, the plug-in unit housing 11 of the electronic device has a stopper member 12 installed in front of the upper guide rail 2 of the pair of guide rails 2 and 3. As shown in FIG. 1, the stopper member 12 is composed of a long plate portion 13 having a long plate shape and a stopper portion 14 bent from the long plate portion 13 at a substantially right angle. The long plate portion 13 has a crank-shaped one end portion 13a, and a crank-shaped through long hole 15 is formed in the other end portion.

One end 13 a of the crank shape is inserted into the rectangular hole 16 of the frame 5, a screw 17 penetrates through the through hole 15, and the screw 17 is screwed into a bent portion of the ceiling plate 18 of the housing 11. It Thus, one end 13a of the stopper member 12 is inserted and supported in the rectangular hole 16 of the frame 5 and the other end is supported by the screw 17, so that the stopper member 12 is positioned in front of the protruding end 2a (FIG. 4) of the upper guide rail 2. Extend along. As shown in FIGS. 1 and 3, when the stopper member 12 is in the retaining position 12A shown by the solid line, the stopper portion 14 contacts the plug-in unit 7, and when it is in the retracted position 12B shown by the broken line, the stopper portion 14 is in contact. Does not contact the plug-in unit 7. The screw 17 fixes the stopper member 12 to the retaining position 12A and the retracted position 12B by tightening. Other configurations are the same as those in FIG.

Next, the operation of this embodiment will be described. As shown in FIG. 4, the stopper member 12 in the stopper position 12A prevents the stopper portion 14 from coming into contact with the plug-in unit 7 housed in the housing 11 and the plug-in unit 7 from coming off. Therefore, the connector plug 8 of the plug-in unit 7 is prevented from being detached from the connector jack 4 of the mother board 1 even if vibration or shock occurs during transportation or use of the electronic device.

When the plug-in unit 7 is added or maintenance is performed, when the screw 17 is loosened and the stopper member 12 is slid to the right in FIGS. 1 and 3, the stopper member 12 becomes a through-hole 15. It is guided by engagement with the screw 17 and moves upward with the above sliding to reach the retreat position 12B. In this state, by tightening the screw 17 to fix the stopper member 12 at the retracted position 12B, the plug-in unit 7 can be easily inserted into the housing 11 or taken out therefrom.

In the above embodiment, the stopper member 12 is attached to the ceiling plate 18 with the screw 17 so as to extend in front of the protruding end of the upper guide rail 2. However, the stopper member 12 can also be directly attached to the projecting end of the upper guide rail 2 by the screw 17. Further, the stopper member 12 can be attached in front of the protruding end of the lower guide rail 3.

[0012]

[Effect of the device]

 As is clear from the above description, according to the present invention, the plug-in unit can be inserted and withdrawn by simply moving the stopper member from the stopper position to the retracted position. It is possible to perform such work extremely easily. Further, since the stopper member does not need to be removed when the plug-in unit is added or maintenance and inspection work is performed, there is no fear that it will be lost during the work.
