  The electronic device described in the embodiment is configured by slidingly storing a plug-in package in which a plurality of electronic components are mounted on a multilayer board in a shelf (also referred to as a housing). In the plug-in package, an external power source connected to a shelf or the like and a connector for electrical or optical connection with an external device are disposed.

  A spring member that suppresses the sliding speed of the slide-in package is provided on the inner wall of the shelf. When the slide-in package is slid and stored in the shelf, the pair of both sides is pressed by the spring member, and the resistance to the storage operation increases due to the frictional force.

  As a result, even if the slide-in package is to be vigorously inserted into the shelf, the storage speed of the slide-in package is reduced, so that it is possible to reduce the concern that the slide-in package will be fitted into the shelf with excessive momentum. Therefore, the connectors of the slide-in package and the shelf are less likely to collide at an excessive speed, and the connectors can be fitted safely and securely.

  Further, for example, the pressing force of the spring member may be increased toward the back so that the slide-in package receives a larger pressing force and the resistance of the storing operation is further increased as it is slid and stored back. As a result, the slide-in package can be decelerated with gradually strong braking so that the connector can be securely and reliably fitted.

  In addition, a plurality of spring members may be attached to any location on a straight line on which the slide rail is arranged so as to press a pair of both sides of the slide-in package. Further, the spring member can be disposed, for example, in an intermittent portion of the slide rail, a through hole, a groove, or the like. Thereby, a space-saving electronic device can be realized.

(First embodiment)
FIG. 1 to FIG. 3 are cross-sectional views in plan view for explaining the configuration and the outline of the slide storage operation from the top of the electronic device 4000 of the first embodiment. The operation of inserting the slide-in package 2000 into the shelf 3030 is sequentially described with reference to FIGS.

  As shown in FIG. 1, the slide-in package 2000 includes a connector 2020 that ensures optical or electrical connection with the shelf 3030. Further, the shelf 3030 includes a connector 3040 that fits with the connector 2020. Further, the shelf 3040 includes a plurality of spring members 3100 that press both sides inward when the slide-in package 2000 is inserted, along the slide rail 3010 on the inner wall.

  Here, opposite side edges of the slide-in package 2000 are fitted into the slide rail 3010, guided by this, and inserted into the back of the shelf 3030. In this case, the spring member 3100 may be provided in the intermittent portion of the slide rail 3010 so that the spring member 3100 can press both sides of the slide rail 3010.

  Further, the slide-in package 2000 may include a card lever 2040 so that the connectors 2020 and 3040 can be more securely and safely fitted. Further, the tip 3150 of the spring member 3100 can be formed in an arc shape so as not to be caught when the slide-in package 2000 is pulled out. The distal end portion 3150 may be formed by, for example, bending the spring member 3100 outward and bending it.

  As can be understood from FIGS. 2 and 3, as the slide-in package 2000 is inserted into the shelf 3030, the spring members 3100 sequentially follow the inner wall of the shelf 3030 from the insertion port (opening) side of the shelf 3030. Tilt and compress. As a result, the side of the slide-in package 2000 is biased by the spring member 3100, and the slide-in package 2000 is braked by the frictional force with the tip 3150 of the spring member 3100.

  Further, it is preferable to provide a plurality of spring members 3100 along the guide direction of slide storage. Thus, the slide-in package 2000 is given a stronger braking force because the number of spring members 3100 that are sequentially pressed increases as the slide-in package 2000 is guided to the back of the shelf 3030. In other words, the slide-in package 2000 immediately before the connectors 2020 and 3040 are fitted is given the braking force by the maximum pressing force as a total from the largest number of spring members 3100, and therefore, the occurrence of collision and impact is suppressed. be able to.

  As shown in FIG. 3, in a state where the slide-in package 2000 is completely inserted into the shelf 3030, the slide-in package 2000 is always pressed from the spring member 3100. For this reason, even when the electronic device 4000 is shaken or vibrated, a pair of both sides of the slide-in package 2000 is pressed and fixed and is preferably firmly held by the shelf 3030.

  FIG. 4 is a diagram for conceptually explaining the spring member 3100 of the first embodiment. 4A is a diagram illustrating a state where the slide-in package 2000 is started to be inserted into the shelf 3030, and FIG. 4B is a diagram illustrating a state where the slide-in package 2000 is being inserted into the shelf 3030. It is a figure to do.

  As can be understood from FIG. 4, the slide rail 3010 of the first embodiment is provided intermittently with respect to the guide direction. In addition, spring members 3100 are provided in the intermittent portions of the slide rail 3010. The spring member 3100 is erected so that the angle with the inner wall of the shelf 3030 gradually increases from the insertion opening of the slide-in package 2000 toward the back.

That is, as shown in FIG. 4A, the spring member 3100 is erected on the inner wall of the shelf 3030 such that θ ₁ <θ ₂ <θ ₃ with respect to the angle between the spring member 3100 and the shelf. Further, for example, the shape and material of the spring may be changed so that the elastic force of the spring member 3100 gradually increases from the insertion opening of the slide-in package 2000 in the depth direction.

  Thereby, as the slide-in package 2000 is guided to the back of the shelf 3030, a larger pressing force is applied from the spring member 3100. That is, as the slide-in package 2000 is guided to the back of the shelf 3030, the sliding operation is braked with a large braking force that is increased at an accelerated rate, so that the connectors 2020 and 3040 can be fitted more safely. be able to.

  Further, as can be understood from FIG. 4B, a space 3155 in which the tip 3150 of the spring member 3100 is accommodated is formed on the inner wall side of the shelf 3030 in a state where the slide-in package 2000 is accommodated. Since the distal end portion 3150 is formed in a spherical shape or is curved outward and formed in an arc shape, an accommodation space corresponding to the case where the spring member 3100 is compressed is required. Correspondingly, a space 3155 in which the distal end portion 3150 of the compressed spring member 3100 is stored is secured on the inner wall of the shelf 3030 of the first embodiment, so that the smooth compression of the spring member 3100 is prevented. Is possible.
