[First Embodiment]
An optical connector cap according to a first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a perspective view showing a state before the optical connector cap 40 (hereinafter also simply referred to as “cap 40”) is attached to the optical connector 10, and FIG. A state in which the connector 10 is mounted is shown in a perspective view. As shown in these drawings, the optical connector 10 is provided with a wedge 26 as an auxiliary part for assisting in assembling the optical connector. As shown in FIG. 2, the cap 40 can be attached to the optical connector 10 to which the wedge 26 is attached.

  First, the configuration of the optical connector 10 will be briefly described. FIG. 5 shows the optical connector 10 as viewed from the direction of the arrow 5 in FIG. In FIG. 5, the wedge 26 indicated by a two-dot chain line is shown in a transparent state. As shown in FIG. 5, the optical connector 10 includes a substantially rectangular tube-shaped housing 14, and a part of the ferrule 12 is accommodated on one end side (left side in the drawing) of the housing 14 in the longitudinal direction. Yes. The ferrule 12 incorporates an optical fiber, and the distal end surface 12A side protrudes from the housing 14.

  A substrate 18 is disposed inside the housing 14, and a groove portion for holding an optical fiber to be connected is formed in the substrate 18. Further, the surface of the substrate 18 where the groove is formed is covered with a lid member 20. A pressing member 22 having a C-shaped cross section is placed on the outer peripheral side of the lid member 20 and the substrate 18, and the pressing member 22 presses the lid member 20 toward the substrate 18 side. A wedge insertion port 16 is formed through the housing 14 so as to correspond to the facing portion between the lid member 20 and the substrate 18.

  Next, the configuration of the wedge 26 will be briefly described. The wedge 26 is a member that pushes the gap between the substrate 18 and the lid member 20, and is inserted between the substrate 18 and the lid member 20 through the wedge insertion port 16 to increase the gap between the substrate 18 and the lid member 20. An insertion blade 28 that spreads out is provided.

  FIG. 4 shows a side view of the wedge 26 attached to the optical connector 10. As shown in FIG. 4B, the insertion blade 28 is formed so as to protrude from the back surface of the holding piece 30, and an operation portion 32 for operator operation is provided on the proximal end side of the holding piece 30. And is integrally formed. Further, as shown in FIG. 1, sandwiching portions 34 are formed to hang from both sides of the operation portion 32, and these sandwiching portions 34 sandwich the side surface of the housing 14 of the optical connector 10. ing. As shown in FIG. 4B, a fulcrum 36 (a linear support portion serving as a rotation center) is provided on the back surface side of the operation portion 32 to be supported by contacting the upper surface on the other end side of the housing 14. The wedge 26 can be rotated around the fulcrum 36. That is, the wedge 26 is attached so as to be movable relative to the housing 14.

  The optical fiber 24 shown on the right side in the figure is connected to the optical fiber of the ferrule 12 in the housing 14 of the optical connector 10. That is, as shown in FIG. 4A, the tip end of the optical fiber 24 is connected to the optical connector 10 with the wedge 26 pushing the gap between the substrate 18 (see FIG. 5) and the lid member 20 (see FIG. 5). As shown in FIG. 4B, the optical fiber 24 is inserted into the housing 14 and the optical fiber 24 is optically connected to the optical fiber 24 as shown in FIG. It is held by the connector 10.

  Next, the configuration of the cap 40 according to this embodiment shown in FIG. 1 and the like will be described. 6 to 11 are six views of the cap 40, FIG. 6 is a front view of the cap 40, FIG. 7 is a rear view of the cap 40, FIG. 8 is a left side view of the cap 40, and FIG. 40 is a plan view, and FIG. 10 is a bottom view of the cap 40. The right side view is omitted because it appears symmetrically with the left side view (FIG. 8).

  As shown in FIGS. 1 and 2, the cap 40 is detachably attached to the optical connector 10, and one end side of the optical connector 10 in the longitudinal direction of the housing 14 (left side in the figure). The cover part 42 which covers 12 A of front end surfaces of the ferrule 12 is provided. The covering portion 42 is formed in a bottomed rectangular tube shape, and includes a concave portion 44 that is directed toward the distal end surface 12A side of the ferrule 12 as shown in FIG.

  On the opening side of the recess 44 of the covering portion 42, a rectangular cylindrical mounting portion 46 is integrally formed (provided integrally) with the covering portion 42. The mounting portion 46 can be mounted (closely attached) to the outer peripheral surface 14B on one end side in the longitudinal direction of the housing 14 (left side in the drawing). Further, a boundary portion between the inner peripheral surface 46A of the mounting portion 46 and the inner peripheral surface 44A of the concave portion 44 in the covering portion 42 has a step shape. That is, the inner diameter D1 of the opening inner peripheral surface 144 of the recess 44 is smaller than the inner diameter D2 of the inner peripheral surface 46A of the mounting portion 46. The connection surface 48 connecting the opening inner peripheral surface 144 of the concave portion 44 of the covering portion 42 and the inner peripheral surface 46A of the mounting portion 46 abuts on the distal end surface portion 14A on one end side in the longitudinal direction of the housing 14, thereby The cap 40 in a state of being attached to the head 10 is positioned.

  As shown in FIG. 1, an overhang 50 is integrally formed (provided integrally) with the mounting portion 46 on the side opposite to the covering portion 42 side of the mounting portion 46. The protruding portion 50 has a shape of a cross section perpendicular to the axis that is formed when the mounting portion 46 is cut in a direction perpendicular to the cylinder axis direction, and has a shape in which the left and right ends of the hat shape are suspended. That is, the overhang 50 is formed by being bent in a direction away from each other from the lower end of the regulation part 52 that constitutes the upper wall, the hanging part 54 that hangs down from both sides of the regulation part 52, and the lower end of the hanging part 54. The horizontal portion 56 and side wall portions 58 respectively suspended from both sides of the horizontal portion 56 are provided. Here, the side wall part 58 constitutes an extension part of the side wall part 146 in the mounting part 46, and the horizontal part 56 constitutes an extension part of the upper wall part 246 in the mounting part 46.

  Here, as shown in FIG. 3A, the restricting portion 52 is in contact with (in close contact with) the surface of the holding piece 30 (site on the action point side) of the wedge 26 when the mounting portion 46 is mounted on the housing 14. The movement of the wedge 26 is restricted. That is, the function of preventing the wedge 26 from being detached is added to the cap 40 by the restricting portion 52. The shape of the projecting portion 50 including the restricting portion 52 depends on the upper surface position of the optical connector 10 and the upper surface position of the holding piece 30 of the wedge 26 when the insertion blade 28 of the wedge 26 is inserted into the optical connector 10. Is set.

  As shown in FIG. 1, a cutout portion 58 </ b> A is formed on the lower side of the side wall portion 58 in order to avoid interference with a jig when the optical connector 10 is installed. Further, a protective cap 59 indicated by a two-dot chain line in FIG. 1 may be attached to the tip side of the ferrule 12 of the optical connector 10 inside the cap 40.

(Action / Effect)
Next, the operation and effect of the above embodiment will be described.

  As shown in FIG. 3 (A), in the cap 40 according to the present embodiment, the covering portion 42 covers the distal end surface 12A of the ferrule 12 at one end side in the longitudinal direction of the housing 14 (left side in the drawing) and covers the covering. A mounting portion 46 formed integrally with the portion 42 can be mounted in close contact with the outer peripheral surface 14B on one end side in the longitudinal direction of the housing 14 by fitting. Further, the restricting portion 52 formed integrally with the mounting portion 46 restricts the movement of the wedge 26 by contacting the wedge 26 in close contact with the mounting portion 46 attached to the housing 14. For this reason, when the mounting portion 46 of the cap 40 is mounted on the housing 14 of the optical connector 10, the distal end surface 12A of the ferrule 12 is covered, and the insertion blade 28 is prevented from coming off (detachment of the wedge 26).

  Here, a supplementary explanation will be made while comparing with the comparison structure. For example, in a comparison structure cap in which the restriction portion 52 is not formed, if the operation portion (32) of the wedge (26) is accidentally pressed, the insertion blade (28) comes off (wedge (26) comes off). If the optical fiber is inserted while the insertion blade (28) of the wedge (26) is half-inserted, connection failure occurs. On the other hand, in the cap 40 according to the present embodiment, the insertion blade 28 is prevented from being pulled out, so that the connection failure of the optical fiber due to the half insertion of the insertion blade 28 can be prevented. On the other hand, in order to prevent the insertion blade (28) from coming off, for example, in another configuration in which the wedge (26) is regulated by a tape or a binding band, it becomes difficult to remove the insertion blade (28). In the case of a tape, there is a disadvantage that the glue sticks to the wedge (26), and there is also a problem that new dust is generated. On the other hand, such a problem does not occur in the cap 40 according to the present embodiment.

  Further, as shown in FIGS. 4A and 4B, around the fulcrum 36 (see FIG. 4B) where the wedge 26 is supported on the other end side (right side in the drawing) of the housing 14. In contrast to the rotational movement (turning), as shown in FIG. 3 (A), the restricting portion 52 is located on the working point side of the wedge 26 when the mounting portion 46 is mounted on the housing 14. The movement of the wedge 26 is restricted by coming into close contact with the surface of the holding piece 30. For this reason, in a state where the mounting portion 46 is mounted on the housing 14, even if the wedge 26 is rotated about the fulcrum 36 with respect to the housing 14, the movement of the wedge 26 is caused by a relatively small reaction force of the restricting portion 52. Is regulated.

  In the cap 40 according to the present embodiment, the connection surface 48 that connects the opening inner peripheral surface 144 of the recess 44 of the covering portion 42 and the inner peripheral surface 46A of the mounting portion 46 is on one end side in the longitudinal direction of the housing 14. The cap 40 in a state of being attached to the optical connector 10 is positioned by contacting the tip surface portion 14A. Therefore, when the mounting portion 46 is mounted in close contact with the outer peripheral surface 14B on one end side in the longitudinal direction of the housing 14, interference between the covering portion 42 and the front end surface 12A of the ferrule 12 is easily avoided. However, the movement of the wedge 26 is regulated by the regulation unit 52.

  As described above, according to the optical connector cap 40 of the present embodiment, the wedge 26 can be prevented from coming off while covering the distal end surface 12A side of the ferrule 12 of the optical connector 10.

  In the optical connector cap 40 according to the present embodiment, the mounting portion 46 is mounted in close contact with the outer peripheral surface 14B on one end side of the housing 14, so that as shown in FIG. Even when the wedge 26 (see FIG. 3A) is removed from the optical connector 10, it can be attached to the optical connector 10.
