  Exemplary embodiments will be described in detail with reference to the drawings. In each drawing, the same or corresponding elements are denoted by the same reference numerals, and redundant description is omitted as necessary for clarification of the description.

  FIG. 1 illustrates an example embodiment communication device.

  In FIG. 1, the communication device 1 has a receptacle 2. An optical module to be described later is inserted into and removed from the communication device 1 via the receptacle 2.

  FIG. 2 shows a cutaway perspective view of the communication device 1 shown in FIG.

  In FIG. 2, the communication device 1 includes a printed circuit board 3, an optical module 4, and a cage 5 in addition to the receptacle 2.

  The printed board 3 is a plate-like circuit board that constitutes an electronic circuit. The printed circuit board 3 is connected to the cage 5. The printed circuit board 3 transmits and receives electrical signals transmitted on the printed circuit board to and from the optical module 4 through the cage 5.

  The cage 5 is provided on the printed circuit board 3 and accommodates the optical module 4 so that it can be inserted and removed. The cage 5 is a box-shaped member having a rectangular section in the front-rear direction with an insertion slot for inserting the optical module 4 on the front side. When the optical module 4 is inserted into the cage 5, the circuit board of the optical module 4 is electrically or mechanically connected to a connector (not shown) in the cage 5. Thereby, an electrical signal is transmitted between the optical module 4 and the printed circuit board 3.

  The optical module 4 is configured to be inserted into and removed from the cage 5. The optical module 4 includes a photoelectric conversion element (not shown), a circuit board, and the like (not shown). On the front surface of the optical module 4, an opening through which an optical fiber connector (optical connector) can be inserted is formed. When the optical connector is connected to the optical module 4, the optical signal transmitted / received by the optical fiber and the electric signal processed by the printed circuit board 3 are mutually converted.

  Here, the optical module 4 is configured to be lockable with a cage 5 that houses the optical module 4. For example, one end of the cage 5 is engaged with a lock portion provided on the bottom surface of the optical module 4, and the optical module 4 and the cage 5 are locked. This one end can be constituted by a leaf spring.

  This lock is released, for example, by rotating a lock release lever provided in the optical module 4.

  For example, when the communication device 1 including the cage 5 that houses the optical module 4 is used outdoors, the space of the opening of the receptacle 2 is limited. For this reason, when exchanging the optical module 4 accommodated in the cage 5, the lock release lever must be operated in a limited space. Thus, since the space for unlocking is limited, it is difficult to operate the unlock lever.

  Furthermore, when downsizing of the communication device 1 is required, the space inside the communication device 1 is further limited. For example, the space between the receptacle 2 and the optical module 4 is limited. In such a case, it is difficult to operate the lock release lever.

  Further, the lock release lever often differs depending on the specification of the provider of the optical module 4. For this reason, the jig | tool for the unlocking according to each provider is required.

  FIG. 3 shows an example of a jig for an optical module in an exemplary embodiment.

  The jig 9 includes a plate 10, a lock release member 11, a folding member 12, a folding member 13, and an operation unit 18.

  The lock release member 11 presses one end of the cage 5 when the jig 9 is moved in the direction in which the optical module 4 is inserted into the cage 5. By this pressing, the lock between the lock part (or convex part) provided on the bottom surface of the optical module 4 and the engagement hole (not shown) provided at one end of the cage 5 is released.

  In FIG. 3, the lock release member 11 is provided between the folding member 12 and the folding member 13. The unlocking member 11 is bent in two stages. The lock release member 11 includes a first member 111 and a second member 112.

  A folding member 12 and a folding member 13 are provided at both ends of one end of the jig 9.

  In FIG. 3, the folding member 12 and the folding member 13 are bent in one stage like a claw.

  The folding member 12 and the folding member 13 are contact surfaces provided on the optical module 4 when the jig 9 moves in the direction of pulling out the optical module 4 after the lock between the optical module 4 and the cage 5 is released. Abut.

  When the jig 9 is moved in the direction in which the optical module 4 is pulled out with the folding member 12 and the folding member 13 in contact with the contact surface of the optical module 4, the optical module 4 is also pulled out together with the jig 9. .

  The operation unit 18 is provided at the other end of the jig 9 and is a part for operating the jig 9.

  As described above, when the jig 9 is pulled back, the folded shape at both ends is caught by the optical module and the optical module is pulled out.

  Note that the unlocking member 11 is not necessarily required to be bent in two stages, and may be one stage. Further, the two-stage bending angle is not limited to the angle shown in FIG.

  FIG. 4 is a cutaway perspective view of another example of the jig of the optical module indicated by the dotted line A in FIG.

  In FIG. 4, an unlocking member 14 is provided at one end of the plate 10 instead of the unlocking member 11 of FIG. 3.

  The unlocking member 14 includes a first member 141 and a second member 142. The second member 142 is bent with respect to the plate 10 at the same angle as the second member 112 of FIG.

  The first member 141 is bent at an angle different from that of the first member 111 in FIG. The first member 141 is bent in a direction away from the extension line of the second member 142.

  FIG. 5 is a cutaway perspective view of another example of the jig of the optical module indicated by the dotted line A in FIG.

  In FIG. 5, an unlocking member 15 is provided at one end of the plate 10 instead of the unlocking member 11 of FIG. 3.

  The lock release member 15 includes a first member 151 and a second member 152. The unlocking member 11 is a substantially rectangular plate. The unlocking member 15 has a curved corner.

  A predetermined space may be provided between the unlocking member 15 and the folding member 12. Similarly, a predetermined space may be provided between the folding member 13 and the lock release member 15.

  When one end of the first member 151 presses (presses down) the leaf spring of the cage 5, the locked state between the optical module 4 and the cage 5 is released. Depending on the width of the leaf spring of the cage 5, the width of the first member 151 or the second member 152 may be determined.

  As described above, the first member 151 of the lock release member 15 has a claw that rises in an R shape at the center of the tip. When the jig 9 is inserted into the communication device 1 from the opening of the receptacle 2, the leaf spring of the cage 5 is pressed by the claw portion at the center of the tip, and the lock is released.

  By being configured in an R shape, the unlocking member 15 can effectively press the leaf spring 6 of the cage 5. Further, when the unlocking member 15 comes into contact with the optical module 4, the receptacle 2, or the like, it is possible to suppress the occurrence of scratches and failures. As described above, the workability of unlocking and drawing out can be improved, and the lifetime of the optical module 4 and the receptacle 2 can be extended.

  FIG. 6 is a cutaway perspective view of another example of the jig of the optical module of FIG.

  In FIG. 6, instead of the folding member 12 and the folding member 13, a folding member 16 and a folding member 17 are provided.

  The folding member 12 and the folding member 13 are formed by being bent linearly with respect to the plate 10. The folding member 16 and the folding member 17 are formed by being bent with respect to the plate 10 in a curved manner. In FIG. 5, the folding member is folded into a V shape. In FIG. 6, the folding member can be folded back into a U-shape.

  FIG. 7 illustrates the unlocking operation in the exemplary embodiment. FIG. 7 is a cross-sectional view of the communication device 1.

  In FIG. 7, the optical module 4 is locked to the cage 5. At this time, the jig 9 is inserted from the opening (opening) of the receptacle 2.

  The jig 9 is inserted into the space between the bottom surface of the optical module 4 and the receptacle 2 along the bottom surface of the optical module 4. When the plate 10 of the jig 9 is inserted in the direction of the arrow, one end of the plate 10 comes into contact with one end of the cage 5. Details of portion B of FIG. 7 are shown in FIG.

  FIG. 8 is a partially enlarged view showing the unlocking operation in the exemplary embodiment.

  In FIG. 8, the lock portion 7 of the optical module 4 is locked in the engagement hole of the leaf spring 6 of the cage 5. At this time, when the plate 10 of the jig 9 is inserted from the direction of the arrow, the lock release member 11 provided at one end of the plate 10 contacts the plate spring 6.

  Thereafter, when the plate 10 further moves in the direction of the arrow, the lock release member 11 presses the plate spring 6. By this pressing, the leaf spring 6 is pushed down in a direction away from the optical module 4, and the lock is released. Details of the operation after the lock is released are shown in FIG.

  FIG. 9 illustrates an optical module removal operation in an exemplary embodiment.

  In FIG. 9, the lock between the lock portion 7 of the optical module 4 and the leaf spring 6 of the cage 5 is released.

  When the plate 10 of the jig 9 moves in the direction of the arrow, one end of the plate 10 comes into contact with a predetermined surface of the bottom surface of the optical module 4. Details of this C portion are shown in FIG.

  FIG. 10 is a partially enlarged view showing the operation of taking out the optical module in the exemplary embodiment.

  In FIG. 10, when the plate 10 of the jig 9 moves in the direction of the arrow, one end of the folding member 13 (and the folding member 12) comes into contact with the contact surface 8 formed on the bottom surface of the optical module 4.

  Thereafter, when the plate 10 further moves in the direction of the arrow, the folding member 13 presses the contact surface 8. By this pressing, the optical module 4 moves in the arrow direction. As a result, the optical module 4 is pulled out from the cage 5. The optical module 4 is taken out of the communication device 1 via the receptacle 2.

  Thus, the optical module 4 is taken out by folding the optical folding module 13 and the folding member 12 by hooking the optical module 4.

  As described above, according to the present embodiment, in the structure in which the optical module can be exchanged from the opening of the receptacle, the optical module which is disposed behind the receptacle and is difficult to take out can be easily exchanged.

  Moreover, even if the member for unlocking the optical module (the shape of the lever, etc.) is different, the lock can be released by the common jig shown in this embodiment.

  By using the jig of this embodiment, the optical module can be easily taken out by an operation from the outside of the receptacle regardless of the shape of the lock release lever of the optical module.

<Other exemplary embodiments>
The folding member 12 and the folding member 13 described above are formed by folding a part of the plate 10. Further, the folding member 12 and the folding member 13 described above may be formed by adding a member different from the plate 10.

  The plate 10 described above has a thin plate shape. However, a shape different from the thin plate shape may be adopted as long as the shape can be inserted into the space between the receptacle 2 and the optical module 4.

  Even if the folding member 13 and the folding member 12 that are opposed to the bottom surface of the optical module (the end portion that abuts against the abutting surface 8) and the first member 111 of the unlocking member 11 are formed to have the same length. Good. As a result, in order to form the folding member 12 and the folding member 13, when part of the plate 10 is folded, the unlocking member 11 111 can be formed at the same time.

  In this case, for example, the folding member 12, the folding member 13, and the first member 111 are first formed. Subsequently, the folding member 12, the folding member 13, and the lock release member 11 are separated. Finally, in order to form the second member 112, only the unlocking member 11 is bent with respect to the plate 10.

  Thus, the jig 9 can be formed by a simple process.

  Further, the unlocking member 11 may be formed to be longer than the folding member 12 or the folding member 13.

  As shown in FIG. 3, the operation unit 18 may be chamfered. For example, the chamfering may be an R chamfering process in which at least one corner is rounded and chamfered. Further, the chamfering may be C (Chamfering) chamfering.

  The plate 10, the folding members 12, 13, 16, 17 and the unlocking members 11, 14, 15 may be formed from a single material.

  The plate 10, the folding members 12, 13, 16, 17 and the unlocking members 11, 14, 15 may be formed by bending a material such as metal.

  Further, the plate 10, the folding members 12, 13, 16, and 17 and the unlocking members 11, 14, and 15 may be formed of resin or the like.
