Description

  The present invention relates to an attachment device for mounting a circuit board on an electronic device.

  In an electronic device in which a plurality of circuit boards (also referred to as “cards”) can be mounted, a plurality of card slots are often provided side by side. However, in such an electronic device, when the user inserts the card into the card slot, the card may be inserted into an incorrect position, thereby causing damage to parts. For such a problem, a card guide having a function of guiding a card to a desired position is generally used.

  As a technique related to a structure for guiding a card, Patent Document 1 discloses a board mounting device. In the substrate mounting apparatus disclosed in Patent Document 1, a substrate guide groove is provided on the inner surface of the case body. The taper portion of the substrate guide groove is gradually and smoothly narrowed from the front (opening) to the back of the inner surface of the case body. In this board mounting apparatus, when the board is inserted, the circuit board can be smoothly and accurately inserted into the board guide groove via the tapered portion.

  Further, Patent Document 2 discloses a printed circuit board mounting structure having a connector guide member that is detachably provided. In the mounting structure disclosed in Patent Document 2, the connector guide is detachably provided on one of the connector on the motherboard side or the connector on the printed circuit board side. This connector guide realizes efficient mounting of the circuit board without manual correction work by guiding the other connector to the fitting position.

  Patent Document 3 discloses a structure of a housing for a circuit board having rail-like protrusions for holding the circuit board on the inner surface of the opening of the case. In the structure of the storage housing disclosed in Patent Document 3, grooves formed by two rail-like protrusions are formed on the left and right inner walls of the case. This rail-shaped protrusion forms an inclined surface on the inner surface on the opening side. The circuit board is guided by the inclined surface and smoothly inserted into the groove formed by the rail-shaped protrusion.

  However, in the board mounting apparatus disclosed in Patent Documents 1 to 3, when a plurality of card slots are close to each other, a portion that is separated from the card guide (opening of the case), such as a gap between the card slots. It cannot be prevented from being mistakenly inserted. This is because, in the above-described board mounting apparatus or the like, a card guide such as an inclined surface for guiding the card is provided on the inner surface of the case, so that the card cannot be guided when the opening is removed. For example, in a situation where a plurality of card slots are arranged, it is easy for a user to mistake the gap between the card slots and the correct insertion slot (card guide receiving slot). There is a lot of danger of inserting a card.

<First Embodiment>
FIG. 1 is a perspective view showing a server 20 including a mounting device 1 according to the first embodiment of the present invention. In FIG. 1, the top plate of the chassis of the server 20 and a part of the front side plate are removed. FIG. 1 shows a state in which several cards (circuit boards) 30 are inserted into the attachment device 1. FIG. 2 is a side view showing a state in which the card 30 is held in the card slots 2a to 2d of the mounting apparatus 1 according to the first embodiment. In FIG. 2, the frame 6 of the mounting device 1 shown in FIG. 1 is transparent.

  Referring to FIG. 1, the attachment device 1 according to the present embodiment is housed in a server 20 that is a server device. The attachment device 1 has a plurality of card slots 2 (corresponding to 2a, 2b, 2c, and 2d shown in FIG. 2) provided between two opposing frames 6. One card slot 2 has a pair of card guides 3 and a connector 4. One of the 12 frames 6 of the mounting device is fixed to the bottom plate 21 and the back plate 22 at a predetermined interval in parallel to the back plate 22 of the chassis of the server 20. The other frame 6 of the attachment device 1 is fixed to the bottom plate 21 so as to face the frame 6 fixed to the back plate 22 with the base board 5 interposed therebetween.

  A plurality of card guides 3 are attached to the inner surfaces of the pair of frames 6 facing each other so as to face each other. A base board 5 is attached to the bottom of the chassis of the server 20 in parallel to the bottom plate 21 with a predetermined distance from the bottom plate 21 of the server 20. A connector 4 corresponding to each set of each card guide 3 is fixed on the upper surface of the base board 5. The connector 4 is connected to a connection terminal provided at the lower end of the card 30 when the card 30 is inserted into the card slot 2.

  As shown in FIG. 2, the card guide 3 includes a card receiving member 15 and a pair of protrusions 10 provided at the upper end of the card receiving member 15.

  FIG. 3 is a perspective view showing the card guide 3 according to the first embodiment. Referring to FIG. 3, the card receiving member 15 has two main bodies 7. The two main bodies 7 are connected by two connecting portions 8 that connect the upper and lower portions of the main body 7 and a connecting portion 9 that connects the middle part of the main body 7. The card receiving member 15 has a receiving port for the card 30 between the two main bodies 7. The upper end of each main body 7 has a protrusion 10 that extends obliquely upward toward the outside with respect to the card receiving member 15 (card receiving port). Further, at least the protrusion 10 is made of a material having elasticity. Examples of the material of the protrusion 10 include a nylon material. A recess 11 having a small thickness is formed at the root of the protrusion 10. Due to the recess 11, the protrusion 10 can swing up and down.

  As shown in FIG. 2, the card slots 2 a to 2 d are arranged so that the protrusions 10 of the adjacent card guides 3 are in contact with each other. That is, the length of the protrusion 10 may be determined according to the interval (pitch) of the card slots 2. In FIG. 2, the interval 41, which is the interval between the card slots 2b, 2c, and 2d, is narrower than the interval 40 between the card slots 2a and 2b. In such a case, the projections 10 that are in contact with each other at a narrower interval 40 can swing upward due to the recess 11 and the elasticity of the material. Therefore, the card guide 3 having the protrusion 10 having the same length can correspond to different intervals of the card slot 2.

  In FIG. 3, each main body 7 has two semicircular holding parts 12 that hold the inserted card 30 inside the card guide 3 at the upper part and the lower part. The two holding portions 12 facing each other are formed at an interval equal to or greater than the thickness of the card 30. That is, the interval between the holding portions 12 facing each other may have a slight margin than the thickness of the card 30. A space between the holding portions 12 at the top of the card receiving member 15 is a receiving port for the card guide 3 (card slot 2) into which the card 30 can be inserted.

  As described above, the card guide 3 is fixed to the frame 6 of the attachment device 1. The two connecting portions 8 and 9 connect the side surfaces of the main body 7 on the side (one side) fixed to the frame 6 so as not to prevent the card 30 from being inserted. In FIG. 3, the connecting portions 8 and 9 join the main body 7 on the back surface in the drawing. Further, the holding part 12 is located in the front direction from the connecting part 8.

  Next, the mounting operation of the card 30 will be described with reference to FIGS. FIG. 4 is a side view showing an operation when the card 30 is inserted into the card slot 2. As shown in FIG. 1, in the server 20, when the card 30 is mounted in one of the card slots 2 of the mounting device 1, the operator can set the center of the pair of card guides 3 in the card slots 2 arranged side by side. It is necessary to insert the card 30 so as to be positioned in the vicinity. At this time, as shown in FIG. 2, since the space between the card slots 2 is blocked by the protrusion 10, the operator erroneously inserts the card 30 into the gap between the adjacent card slots 2. There is no fear.

  Further, as shown in FIG. 4, when the card 30 is inserted out of the receiving opening of the card guide 3, the protrusion 10 can guide the card 30 toward the center of the card guide 3. That is, even if the receiving opening of the card guide 3 is removed, the operator can normally insert the card 30 into the receiving opening of the card guide 3 by sliding the card 30 along the inclination of the protrusion 10. After the insertion, the operator inserts the card 30 to the connector 4 while receiving guidance from the upper and lower holding portions 12. This completes the mounting of the card 30.

  Thus, according to the present embodiment, there is an effect that it is possible to prevent erroneous insertion of the card (circuit board) 30 into the plurality of card slots 2.

  This is because the protrusion 10 provided on the upper portion of the card guide 3 and extending obliquely upward toward the outside of the card guide 3 can block the gap between the card slots 2. That is, the attachment device 1 according to the present embodiment does not have a gap that may cause the operator to mistakenly recognize the card slot 2 as a receiving port.

  In addition, this embodiment has an effect that it is possible to cope with different intervals of the card slot 2 by the same card guide 3.

  The reason is that the protrusion 10 provided on the upper portion of the card guide 3 can swing in the vertical direction by the recess 11 and the elasticity of the material.

  In addition, this embodiment has an effect that the card 30 can be smoothly inserted into the receiving port of the regular card guide 3 even when the card 30 is inserted out of the receiving port of the card guide 3.

  The reason is that the protrusion 10 can guide the card 30 toward the center of the card guide 3 along the inclination of the protrusion 10.

  In addition, the following can be considered as a modification of this embodiment.

  For example, the shape and size of the server 20 that houses the attachment device 1 are not limited to this embodiment. Further, the position where the mounting device 1 is mounted on the server 20 is not limited to this embodiment. For example, the attachment device 1 may be exposed outside the server 20. Moreover, the attachment apparatus 1 can be mounted also on apparatuses other than a server.

  Moreover, if the number of the card slots 2 which the attachment apparatus 1 has is one or more, it will not be restricted to this embodiment.

  Further, the shapes of the frame 6, the connecting portions 8 and 9 of the card guide 3, and the holding portion 12 are not limited to this embodiment. The numbers of the connecting portions 8 and 9 and the holding portions 12 are not limited to the present embodiment.

<Second Embodiment>
Next, a second embodiment based on the above-described first embodiment will be described. In the following, the characteristic part according to the second embodiment will be mainly described, and the components of the second embodiment having the same configuration as the first embodiment are attached in the first embodiment. The same reference numerals as those of the reference numerals are attached, and the detailed description of the constituent elements is omitted.

  This embodiment is different from the first embodiment described above in that the card 30 inserted into the card slot 2 is supported so as not to rattle due to vibration. FIG. 5 is a perspective view showing a card guide 103 according to the second embodiment of the present invention. As shown in FIG. 5, the card guide 103 according to the present embodiment further includes two sets of support portions 113 and a support plate 114 in addition to the structures of the card guide 3 according to the first embodiment. This embodiment is realized by replacing the card guide 3 of the attachment device 1 according to the first embodiment with a card guide 103.

  The main body 107 included in the card receiving member 115 of the card guide 103 has two arc-shaped support portions 113 inside the two holding portions 12. That is, two opposing support portions 113 are formed inside the card receiving member 115. Further, the connecting portion 9 in the middle of the card receiving member 115 has a dog-shaped support plate 114. The support portion 113 and the support plate 114 have a shape in which one end is supported by the main body 107, and thus have a spring property (elasticity). Note that the support portion 113 and the support plate 114 may be made of a material having elasticity.

  FIG. 6 is a side view showing the relationship between the distance between the support portions 113 of the card guide 103 and the thickness of the card 30 according to the second embodiment. Referring to FIG. 6, the interval 42 between the opposing support portions 113 is formed to be narrower than the thickness 43 of the card 30. Although omitted in FIG. 6, the interval between the lower support portions 113 is the same as the interval 42 between the upper support portions 113 described above. Further, the support plate 114 is formed obliquely so as to protrude from the connecting portion 9 located in the back direction of FIG. 6 toward the front side. That is, the support plate 114 is attached obliquely to the connecting portion so as to protrude in a direction opposite to the side surface of the main body 107 to which the connecting portion is connected. The interval between the support plates 114 of the opposing card guides 103 is formed to be narrower than the width 44 of the card 30 to be inserted.

  FIG. 7 is a side view showing a state in which the card 30 is inserted into the card slot 2 having the card guide 103 according to the second embodiment. When mounting the card 30, the operator inserts the card 30 while pushing down the two sets of support portions 113 and support plates 114 downward from the receiving port of the card guide 103. Therefore, as shown in FIG. 7, a part of the front and back surfaces of the inserted card 30 is always in contact with a part of the surface of the support 113 while being urged by the elastic force of the support 113. ing. That is, the inserted card 30 is held by the support portion 113 so as to reduce the vibration in the thickness direction. Further, a part of the side surface of the inserted card 30 is always in contact with the support plate 114 while being urged by the elastic force of the support plate 114. That is, the inserted card 30 is held by the support plate 114 so as to reduce the vibration in the width direction in particular.

  As described above, in addition to the same effects as those of the above-described first embodiment, the present embodiment also has an effect of reducing vibration with respect to the card 30 after insertion. As a result, the mounting apparatus 1 (card guide 103) according to the present embodiment can be expected to prevent a component failure of the card 30 caused by external vibration such as a fan of the server 20 being transmitted to the card 30.

  The reason is that the support portion 113 and the support plate 114 having elastic force reduce vibrations by holding the inserted card 30.

  In addition, the following can be considered as a modification of this embodiment.

  For example, the shape, size, position, and number of the support part 113 and the support plate 114 are not limited to the present embodiment. For example, the positions of the support part 113 and the holding part 12 may be switched. Moreover, a part or all of the holding part 12 may be omitted.
