JP 2002-372634 A

  In the conventional mounting structure shown in FIGS. 6 and 7, the latch 107 is provided at both ends of the two adapter panels 106, and the adapter panel 106 is mounted by inserting the latch 107 into the hole 102 on the front surface of the chassis 101.

  In the conventional mounting structure shown in FIG. 8, when three adapter panels 206 are mounted, the space occupied by the latch 207 is reduced by forming both ends of the adapter panel 206 so as to overlap each other.

  Further, as shown in FIGS. 6 and 8, protective covers 116 and 216 for receiving a large number of optical cords are integrally formed with the chassis 101 and 201, and extended to the front of the adapter panels 106 and 206, so that the optical adapter 108, Techniques for protecting 208 are also known.

  However, according to the prior art shown in FIGS. 6 and 7, a space for arranging the two latches 107 is required at a place where the two adapter panels 106 are adjacent to each other. Therefore, there is a problem that the number of optical adapters 108 that can be installed on the adapter panel 106 is limited.

  According to the prior art of FIG. 8, the space occupied by the latch 207 is reduced by shifting the position of the latch 207 above and below the adapter panel 206, but the shape of the adapter panel 206 is complicated, and the processing location is There are problems such as an increase in the number of latches 207 and the like.

  An object of the present invention is to provide an adapter panel mounting structure that can solve the above problems, reduce the number of latches, and improve the mounting density of optical adapters.

  In order to achieve the above object, an adapter panel mounting structure according to the present invention includes a plurality of optical adapters for connecting optical cords, and an adapter panel that can be attached to and detached from a chassis by a latch. The adapter panel is attached to the chassis by providing a claw-like protrusion at the other end and fitting the protrusion into an opening provided in the chassis.

  Moreover, this invention provides the structure suitable for attaching both an adapter panel and a separation-type protective cover to a chassis. In this mounting structure, the opening is provided in a latching part separate from the chassis, the latching part is attached to the center part of the chassis, both ends of the separable protective cover are attached to both ends of the chassis, and the center part of the cover is attached. Is reinforced by a reinforcing portion provided in the latching part.

  According to the mounting structure of the present invention, a claw-like protrusion is provided at one end of the adapter panel, and the protrusion is fitted into the opening, so that the space for mounting the latch can be reduced, and the mounting density of the optical adapter can be reduced. It can be higher than before.

  In addition, by providing an opening and a reinforcing portion in a latching component that is separate from the chassis, this component can be used both for attaching the adapter panel and reinforcing the separation type protective cover.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the chassis and the adapter panel separately. FIG. 2 shows a procedure for attaching the adapter panel to the chassis. FIG. 3 shows an embodiment in which the adapter panel mounting portion is integrally formed with the chassis. FIG. 4 shows a separable protective cover. FIG. 5 shows a mounting structure of the separation type protective cover.

  As shown in FIG. 1, in this embodiment, two left and right adapter panels 6 are detachably attached to the front end of the chassis 1 by a latch 7 and a latching part 11. A plurality of optical adapters 8 are attached to the adapter panel 6. The chassis 1 is attached to a splice unit or an optical patch panel (not shown), and an optical cord is connected to the optical adapter 8.

  The front panel 1a of the chassis 1 is formed with a mounting hole 2 for the latch 7, a pair of left and right slits 3 into which the optical adapter 8 on the adapter panel 6 is fitted, and a mounting portion 4 for the latching component 11. .

  On the adapter panel 6, a plurality of optical adapters 8 for connecting optical cords are mounted obliquely with respect to the adapter panel 6. One end of the adapter panel 6 is provided with a latch 7 that is locked to the latch mounting holes 2 located at both ends of the front panel 1a. At the other end of the adapter panel 6, a claw-like protrusion 9 is provided that is hooked by a hooking part 11 located at the center of the front panel 1 a.

  As shown in FIG. 2, the latching component 11 is formed separately from the chassis 1, and is attached to the attachment portion 4 of the front panel 1 a from the back side by the fastening tool 10. The latching part 11 has a pair of left and right latching parts 12 and a reinforcing part 13 bent forward. The hook 12 is provided with an opening 5 for hooking the claw-shaped protrusion 9 of the adapter panel 6, and a hole 14 for attaching the separation type protective cover 16 to the reinforcing part 13.

  As shown in FIG. 3 (a), the opening 5 into which the claw-shaped protrusion 9 is fitted is formed in the latch piece 15 integrated with the front panel 1a, and as shown in FIG. It is also possible to bend the piece 15 forward so that it functions in the same manner as the hooking part 11.

  In order to attach the adapter panel 6 to the chassis 1, first, the claw-shaped protrusion 9 at one end of the adapter panel 6 is fitted into the opening 5 of the latching portion 12 or the latching piece 15, and then the other end of the adapter panel 6 is The latch 7 is locked in the latch mounting hole 2 of the front panel 1a. In this way, the adapter panel 6 can be attached to the chassis 1 with one latch 7.

  As shown in FIGS. 4 and 5, when using the separation type protective cover 16, the right and left ends of the cover 16 are attached to the mounting holes 21 provided at both ends of the front panel 1 a with the fastening tool 19. Then, the central portion of the protective cover 16 is reinforced by the reinforcing portion 13 of the latching component 11. The separation type protective cover 16 is provided with a through hole 20 corresponding to the mounting hole 21 of the front panel 1 a and a through hole 17 corresponding to the mounting hole 14 of the reinforcing portion 13. The separation type protective cover 16 is provided with an optical cord binding tool 22 that binds and holds the optical cord connected to the optical adapter 8.

  In order to attach the separation type protective cover 16 to the chassis 1, the fastening tool 19 is fastened to the attachment hole 21 of the front panel 1 a through the through hole 20 of the separation type protective cover 16, and the fastening tool 18 is attached to the through hole of the separation type protective cover 16. 17, and tightens into the mounting hole 14 of the reinforcing portion 13. If it carries out like this, the deflection | deviation of the separation-type protective cover 16 can be prevented using the latching component 11 which is an attachment component of the adapter panel 6. FIG.

According to the adapter panel mounting structure having the above configuration, the following effects can be expected.
(A) By providing the claw-shaped protrusion 9 at one end of the adapter panel 6, the adapter panel 6 can be attached to and detached from the chassis 1 by one latch 7.
(B) Since the number of latches 7 is reduced, the mounting density of the optical adapters 8 in the adapter panel 6 can be improved.
(C) The shape of the adapter panel 6 can be simplified and the processing cost can be reduced.
(D) The latching component 11 can have both the attachment function of the adapter panel 6 and the reinforcement function of the separation type protective cover 16.
