Description

  The present invention relates to an adapter holder used to collectively hold adapters for connecting optical cable connectors in mounting holes of an adapter mounting panel.

  2. Description of the Related Art Conventionally, as a structure for attaching an adapter for connecting an optical cable connector to a mounting panel, a structure in which a screw hole is provided in the adapter and directly screwed to the mounting panel is known. However, since this structure screws individual adapters directly onto the mounting panel, it takes a considerable amount of time and labor for the mounting operation. In order to solve this problem, structures shown in Patent Documents 1 and 2 have been proposed.

  Patent Document 1 describes a structure in which an adapter equipped with a locking tool is attached to the mounting panel by sandwiching the adapter between the locking tool and the mounting panel. However, since this structure requires one locking tool for each adapter, the number of parts increases. In addition, the adapter is not fixed to either the locking tool or the mounting panel, and the adapter may fall during work.

  On the other hand, Patent Document 2 describes a structure in which a plurality of adapters are sandwiched between a locking tool and a mounting panel, and are attached to the mounting panel by screwing four corners of the locking tool. In this structure, the adapter can be temporarily held on the mounting panel when being attached to the mounting panel, but since the adapter is not fixedly held, there is still a risk that the adapter will fall during work. Further, even when it is desired to replace one adapter, since the locking tool must be removed from the mounting panel, there arises a disadvantage that the adapter that is not scheduled to be replaced is detached from the mounting panel.

  Hereinafter, preferred embodiments of the present invention will be described. An adapter holder according to the present invention is used in an optical line distribution device called a splice unit, and collectively holds a plurality of adapters for connecting a connector of a primary side optical cable and a connector of a secondary side optical cable in the splice unit. Used for. The optical cable is a bundle of a plurality of optical fibers.

  As shown in FIGS. 1 and 2, the splice unit 1 includes a box-shaped fixing portion 2 that is attached to a rack mounting angle and the like, and slide rails 31 on both side surfaces. The slide part 3 is slidable back and forth. A plurality of cable guides 5 a are formed inside the fixed portion 2 to hold the cable drawn from the optical cable insertion port 4 into the splice unit 1 so that the cable can be stretched and contracted. On the other hand, a cable guide is formed in the slide portion 3 so as to communicate with the plurality of cable guides 5 a formed in the splice unit 1 and guide the primary side optical cable held by the cable guide 5 a to the slide portion 3. 5b, a fusion tray 6 formed so as to be stackable and fusing the cores of the optical cables on the primary side and the secondary side inside, and the extra length of the optical cable or the core of the optical cable below the fusion tray 6 A surplus length tray 7 is provided. An attachment panel 8 having a plurality of attachment holes 81 is attached to the outer surface of the slide portion 3, and the adapter holder 9 is attached to the attachment hole 81. As shown in FIG. 3, the adapter holder 9 can hold four square cylindrical adapters 10.

  As shown in FIGS. 4 and 5, the adapter holder 9 includes a hollow body 91 having a substantially quadrangular prism shape whose front and back surfaces are open, and two pairs of adapter holding pieces 92 formed on both side surfaces of the hollow body. It consists of a pair of panel locking pieces 93 formed behind the adapter holding pieces 92. Both side surfaces of the hollow main body 91 include a clamping piece mounting surface 94 on which the adapter clamping piece 92 is formed, and a locking piece mounting surface 95 extending from the rear end side of the clamping piece mounting surface 94 in the insertion direction of the adapter. It is composed of

Two pairs of adapter clamping pieces 92 are formed on the clamping piece mounting surface 94 in two upper and lower stages. Each adapter clamping piece 92 is inclined inward along the insertion direction of the adapter 10 and clamps the two adapters 10 as a pair with the adapter clamping piece 92 on the opposite surface. Thereby, since the adapter 10 is hold | maintained in the hollow main body 91 by a pair of adapter clamping piece 92, the adapter 10 does not fall from a hollow main body in the case of an operation | work.
Moreover, since the adapter clamping piece 92 is an elastic piece, the adapter 10 can be firmly clamped without using a screw. Further, a protrusion 96 for releasing the holding by the adapter holding piece 92 is formed above or below the tip of the adapter holding piece 92. When it is necessary to remove the adapter, for example, when the adapter is replaced, it is possible to release the holding by the adapter holding piece 92 by hooking a tool on the protrusion 96 and spreading the tool outward. In the present embodiment, the two pairs of adapter holding pieces 92 are used. However, appropriate modifications such as holding four adapters with a pair of adapter holding pieces are possible.

  A panel locking piece 93 is formed at the center of the locking piece mounting surface 95. Each panel locking piece 93 is inclined outward along the adapter removal direction. When the adapter holder is attached to the mounting panel 8, the panel locking piece 93 is paired with the panel locking piece 93 on the opposite surface and the periphery of the mounting hole 81. Lock to. Thereby, the several adapter 10 accommodated in the hollow main body 91 can be attached to the attachment panel 8 by one touch. Moreover, since the panel latching piece 93 is made into the elastic piece, it can attach firmly, without using a screw. In the present embodiment, the adapter holding piece 92 and the panel locking piece 93 are provided on both side surfaces of the hollow body 91. Thus, if both pieces 92 and 93 are formed on the same surface, it is only necessary to provide a working space outside the surface on which both pieces 92 and 93 are formed. Therefore, adapter holding piece 92 and panel locking piece 93 are provided. More adapters 10 can be arranged on the mounting panel 8 than when the two are formed on different surfaces.

  Further, in the present embodiment, the sandwiching piece attachment surface 94 is formed to be stepped slightly outward from the locking piece attachment surface 95. In the case where the clamping piece mounting surface 94 and the locking piece mounting surface 95 are formed flat, if the inclination angle of the adapter clamping piece 92 is increased, the insertion range of the adapter 10 becomes narrow, so that the insertion becomes difficult, and if the inclination angle is reduced. The adapter 10 is easily pulled out. On the other hand, as in this embodiment, the adapter holding piece 92 can be formed long if formed in a stepped manner, so that the adapter 10 can be easily inserted even if the inclination angle is small, and the structure is difficult to remove. be able to.

  Moreover, the step part 97 which connects the clamping piece attachment surface 94 and the latching piece attachment surface 95 is formed by forming in a level | step difference. As will be described later, the stepped portion 97 is composed of one side for holding the protruding piece 11 of the adapter 10 and one side for holding the mounting panel 8. In addition, when the clamping piece attachment surface 94 and the locking piece attachment surface 95 are formed flat, it is necessary to separately form a clamping portion that clamps the adapter 10 and the mounting panel 8.

Further, the adapter 10 in the hollow body 91 is sandwiched from the front and rear by the stepped portion 97 and the end of the adapter sandwiching piece 92 in addition to the sandwiching from the left and right by the adapter sandwiching piece 92, so Retained. On the other hand, the adapter holder 9 attached to the attachment panel 8 has the attachment panel 8 formed by the stepped portion 97 and the end of the panel engagement piece 93 in addition to the panel engagement piece 93 being engaged with the periphery of the attachment hole 81. Is securely held by the mounting panel 8. That is, one surface of the stepped portion 97 becomes a panel clamping surface that sandwiches the mounting panel 8 with the panel locking piece 93, and the other surface sandwiches the protruding piece 11 of the adapter 10 with the adapter clamping piece 92. It is the adapter clamping surface. Here, as shown in FIG. 5, in the present embodiment, a gap is formed between the protruding piece 11 of the adapter 10 and the tip of the adapter holding piece 92, but it is not limited to this shape. Needless to say, the protruding piece 11 and the adapter holding piece 92 may be formed so as to be in contact with each other and clamped. In any structure, even if the adapter 10 is pushed in, the protruding piece 11 comes into contact with the stepped portion 97, and even when trying to pull out, the protruding piece 11 comes into contact with the holding piece 92, so that the adapter 10 will not fall out.

  Hereinafter, the mounting structure of the adapter 10 will be described. As shown in FIG. 6, the adapter 10 accommodated in the hollow main body 91 has a quadrangular cylindrical shape, and a protruding piece 11 is formed in a vertical direction at the center of both side surfaces. As shown in FIG. 7, when the adapter 10 is inserted into the front opening of the hollow body, the adapter 10 moves in the hollow body while the protruding piece 11 bends the adapter holding piece 92 outward, and the protruding piece 11 is a stepped portion. Stop when 97 is touched. In this state, the protruding piece 11 is fitted between the stepped portion 97 and the end portion of the adapter holding piece 92. In addition, when the protruding piece 11 contacts the stepped portion 97, the adapter 10 stops at a fixed position without passing through the hollow body 91.

  Next, when the hollow main body 91 is pushed into the attachment hole 81 of the attachment panel 8, the panel locking piece 93 is pressed against the periphery of the attachment hole 81 and passes through the attachment hole 81 while bending inward. As shown in FIG. 8, the panel locking piece 93 that has passed through the mounting hole 81 is locked to the periphery of the mounting hole 81 while sandwiching the mounting panel 8 between the end portion and the stepped portion 97. In addition, although the adapter 10 was attached to the adapter holder 9 and the adapter holder 9 was attached to the attachment panel 8 in the order of attaching the adapter 10 here, it is not limited to this.

  As described above, since the adapter holder 9 according to the present invention can hold the adapter 10 by the adapter holding piece 92, the risk of the adapter 10 falling during work can be avoided. Moreover, since the several adapter 10 hold | maintained at the adapter holder 9 can be collectively attached to the attachment panel 8 with the panel latching piece 93, it is excellent in workability | operativity. Furthermore, when it is desired to remove the adapter 10 such as when the adapter 10 is replaced, it is possible to replace only the desired adapter 10 by hooking a tool on the protrusion 11 and releasing the clamping by the adapter clamping piece 92.
