Description

  The present invention relates to a cabinet for storing electrical and electronic equipment having a handle device on a door. In particular, the internal equipment is an information communication equipment, and the electrical and electronic equipment is suitable for applications in which a large number of communication lines such as optical fibers are drawn. The present invention relates to an equipment storage cabinet.

  In general, electrical and electronic equipment storage cabinets have a structure in which a handle device is attached to a door and locked for the purpose of safety and security for preventing third parties from touching internal equipment. As a handle device, for example, as disclosed in Patent Document 1, a handle device that is disposed at a position inside an opening of a cabinet body at the end of a door is generally used. In the locked state, the handle device has a handle housed in the handle body. When the handle is raised and rotated 90 degrees, the locking piece attached coaxially with the handle rotates to engage the cabinet body. It is a structure that can be detached from the part and open the door.

  In this case, the handle faces the 6 o'clock direction in the locked state so as to maintain a stable position by its own weight, and in the case of a right-open cabinet with a hinge on the right side, the locking piece is at the 9 o'clock position. Is engaged with the cabinet body. If the handle is pushed into the handle body and fixed in this position, the locked state is maintained. When unlocking, the handle is raised from the handle body and operated from the 6 o'clock position to the 3 o'clock direction. In accordance with this operation, the locking piece rotates from the 9 o'clock position to the 6 o'clock position, and is released from the handle body to enter the unlocked state. Needless to say, when locking, the locking piece rotates from the 6 o'clock position to the 9 o'clock position.

  However, in the unlocked state, when the locking piece at the 6 o'clock position is rotated to the 9 o'clock position for locking, the locking piece moves from the inside to the outside of the right-open cabinet, There is a possibility that a communication line such as an optical fiber wired with the door opened is pulled outside while being caught by the locking piece and damaged. If this happens, the discovery will be delayed because the door is locked.

  In addition, it is also performed to form a partition wall at the end portion of the cabinet to prevent such wiring from being caught. However, there is a problem that the cabinet structure becomes complicated and the cost increases.

Embodiments of the present invention will be described below.
FIG. 1 is an external perspective view showing a cabinet for storing electrical and electronic equipment according to an embodiment. 1 is a cabinet body, and 2 is a door that covers the opening. Although all the drawings are drawn with the cabinet body 1 in a horizontal state, the cabinet body 1 is in a vertically upright state in use. The door 2 is a right opening door pivoted on the right side with a hinge (not shown). The electrical / electronic equipment storage cabinet of this embodiment is an optical fiber junction box. On the opposite side of the door 2 from the hinge, a handle device 4 having a rotary handle 3 is provided as in the prior art.

As shown in FIGS. 2 and 3, the handle device 4 includes a substantially rectangular handle device body 5 and a rectangular handle 3 pivotally attached to the handle device body 5 so as to be raised and lowered. . 2 and the subsequent drawings are drawn with the door 2 omitted. 4 is a rear view in the state of FIG. 2, and FIG. 5 is a rear view in the state of FIG. As shown in FIGS. 2 and 4, the handle device 4 includes a locking piece 6 extending in the longitudinal direction of the handle 3. As shown in FIGS. 4 and 5, the distance OA from the rotation center O of the locking piece 6 to the end A is set larger than the distance OB to the end B. The locking piece 6 is provided in the longitudinal direction of the handle 3, and has a shape that fits within the lateral width of the handle device body 5 at the locked position as shown in FIG.

  The locking piece 6 is rotated by rotating the handle 3. In the state shown in FIG. 2, the locking piece 6 engages with the hook-shaped engaging portion 7 of the cabinet body 1 to lock the door 2. The handle device 4 is located in front of the engaging portion 7 of the cabinet body 1. As shown in FIG. 6, the engaging portion 7 of the cabinet body 1 is provided with a right-opening engagement portion 7 a and a left-opening engagement portion 7 b at the upper and lower sides, which are the open ends of the cabinet body 1. It is formed in a vertical side portion 8 that is bent to the door 2 side. As shown in FIG. 6, the protruding portion on the back surface of the handle device main body 5 is accommodated in the space between these engagement portions with the door closed. As shown in FIGS. 2 and 3, the engaging portion 7 is located outside the opening end portion 9 of the cabinet body 1.

When the rotary handle 3 is raised from the state of FIG. 2 and rotated in the direction of the arrow 10, the locking piece 6 rotates on a plane parallel to the plane of the door as shown in FIGS. , Disengaged from the hook-shaped engagement portion 7. For this reason, the locked state is released and the door 2 can be opened. At this time, the distal end portion of the locking piece 6 is positioned outside the vertical side portion 8 formed at the opening end portion 9 of the cabinet body 1. On the contrary, when the handle 3 is rotated in the opposite direction of the arrow 10 from the state of FIG. 3, the locking piece 6 is rotated in the clockwise direction to the position of FIGS. That is, when going from the unlocked position to the locked position, the locking piece 6 has a rotation trajectory from the outside to the inside of the cabinet.

  The movement of the locking piece 6 described above will be described again. When the handle 3 is in the unlocked state of FIG. 3, the locking piece 6 is in a position disengaged from the hook-shaped engagement portion 7. When the handle 3 is rotated in the direction of FIG. 2 from this state, the locking piece 6 rotates from the outside of the cabinet body 1 toward the inside position and engages with the engaging portion 7. That is, when the handle 3 is rotated from the 3 o'clock position to the 6 o'clock position, the locking piece 6 moves from the 9 o'clock position to the 12 o'clock position. Thus, when performing the locking operation, the locking piece 6 has a rotation trajectory from the outside of the cabinet body 1 toward the inside position, and the engaging portion 7 is located outside the opening end 9 of the cabinet body 1. Therefore, there is no possibility that the communication line such as the optical fiber is broken by the locking piece 6 at the time of locking. Therefore, unlike the conventional case, even if the cabinet body 1 is not provided with a partition wall for preventing the wiring from being caught, there is no possibility that the communication line such as the optical fiber is broken by the locking piece 6 at the time of locking.

  In the above-described embodiment, the engaging portion 7 on the cabinet body 1 side is formed in the vertical side portion 8 where the opening end portion 9 of the cabinet body 1 is bent to the door 2 side, and when the door 2 is to be opened. Since the force received by the engaging portion 7 acts in the direction of the plate surface of the vertical side portion 8, the structure can be made excellent in strength. Further, as shown in FIG. 7, the width of the handle device 5 can be reduced, the handle device 5 can be positioned at the outer end of the door 2, and the engaging portion 7 is also an open end of the cabinet body 1. 9, the internal space of the cabinet body 1 can be widely used.

  In the above-described embodiment, the handle 3 is a type in which the handle 3 is erected from the handle device body 5 and rotated. However, the structure of the handle 3 is not limited to this. Various types can be used, such as a type in which the handle is rotated or a type in which a substantially T-shaped or L-shaped handle is detachable.

  In the above-described embodiment, the engaging portion 7 of the cabinet body 1 is provided with the right-opening engagement portion 7a and the left-opening engagement portion 7b in the vertical direction. Therefore, if the locking piece 6 is formed in the longitudinal direction of the handle 3 as described above, the opening direction of the door 2 can be easily changed to either the left or right simply by turning the handle device 4 upside down. At this time, since the handle 3 and the engagement piece 6 have the same relative position, it is only necessary to remove the handle device from the door and invert it, and there is no need to change the attachment direction of the engagement piece. For this reason, workability | operativity can be improved.

  In the above-described embodiment, the engaging portion 7 of the cabinet body 1 is formed on the bent vertical side portion 8. However, as shown in FIG. 8, the plate material may be bent from the top and bottom to have a substantially C shape. Good. With this structure, since the guide portion can be provided on the engaging portion side, a smooth locking operation can be performed.

  Hereinafter, the internal structure of the cabinet body 1 according to the embodiment will be briefly described with reference to FIG. As described above, this electrical / electronic equipment storage cabinet is used as an optical fiber junction box. In the optical fiber connection box, there are connection parts that may be operated by a person and parts that are unlikely to be operated by a person. Therefore, the interior of the cabinet body 1 is divided into a plurality of stages, and the first stage close to the bottom is a storage part for parts with a low possibility of operation, and the second stage is a storage part for parts with a high possibility of operation. In this embodiment, a third stage is also provided.

  Specifically, the first stage of the cabinet body 1 has an optical fiber connecting portion 11 for receiving an optical fiber and an extra length tray 12 for accommodating the extra length portion of the optical fiber (on the engaging portion 7). It is arranged on the near side. A leg portion 13 is arranged on the right side, and a lower space thereof is an electric wire storage space 14.

  A rotating first wiring partition plate 15 is pivotally mounted above the surplus length tray 12 via a vertical plate 16, and when the first wiring partition plate 15 is lowered as shown in FIG. The media converter 17 is mounted with the upper surface as the second stage. The power line 18 of the media converter 17 is stored in the above-described electric wire storage space 14.

  An adapter connection portion 19 is mounted on the upper portion of the leg portion 13. The adapter connection portion 19 is located on the lateral side of the first wiring partition plate 15. The end of the leg 13 supports and fixes the tip of the first wiring partition plate 15. Specifically, as shown in FIG. 11, the first wiring partition plate 15 and the hole portion 20 of the leg portion 13 are combined and engaged by a one-touch engagement portion.

  In the third stage, as shown in FIGS. 12 and 13, the second wiring partition plate 21 is provided above the second stage and is formed on the upper surface thereof. Although the second wiring partition plate 21 is attached to the cabinet body 1, it can also be attached to the first wiring partition plate 15 or the mounting portion of the adapter connection portion 19. In the third stage, devices connected to communication devices are arranged. Specifically, a switching hub, which is a metal device, and a communication device 22 such as a router are mounted.

  Usually, the adapter connection portion 19 of the optical fiber is attached to a device mounting plate, and even in a laminated structure, it is often arranged at the first stage, but in this embodiment, it is positioned at the second stage and the first stage below it. Since the wiring storage space 14 is used as an eye, the internal space can be used effectively, the cabinet size of the cabinet body 1 can be reduced, and the workability is improved.
