2. Description of the Related Art Conventionally, an optical cable adapter (hereinafter referred to as an optical adapter) that optically connects a first optical cable and a second optical cable provided with a connector on one end side has been widely used.
The optical adapter has a substantially rectangular shape in sectional view having a pair of first side walls and a pair of second side walls facing each other, and is provided with a flange extending outwardly between one end side and the other end side, and one end Connector mounting holes are provided on the side and the other end side, respectively, to which the connectors of the first and second optical cables are detachably connected.

Further, an adapter mounting panel for holding the optical adapter, which is provided with a mounting hole into which the optical adapter is inserted, has been widely used conventionally (see, for example, Patent Document 1 below). .
Patent Document 1 discloses an adapter mounting bracket that is mounted on the optical adapter in order to mount the optical adapter in the mounting hole of the adapter mounting panel without rattling.
FIG. 11 is a perspective assembly view when an optical adapter is mounted on an adapter mounting panel using a conventional adapter mounting bracket.

  Specifically, as shown in FIG. 11, the adapter mounting bracket P4 is bent in a direction substantially orthogonal from both ends of the connecting plate portion P5 and the connecting plate portion P5, and to the optical adapter (LC type optical adapter) L1. Are integrally provided with a pair of side plate portions P6 respectively opposed to the pair of side walls (first side walls) L11 of the optical adapter L1.

  Each of the pair of side plate portions P6 has a distal end portion which is in contact with the side wall L11 of the optical adapter L1 corresponding to the proximal end portion and extends from the proximal end portion to one side in the axial direction of the optical adapter L1 as a free end portion. The elastic locking claw P8, which is spaced from the corresponding first side wall as it goes from the base end portion to the distal end portion, and from the elastic locking claw P8 to the connecting plate portion P5 A first side plate P10 that is located on the adjacent side, has a proximal end abutting against the corresponding side wall L11, and a distal end extending from the proximal end to one side in the axial direction of the optical adapter L1 as a free end. The first side plate piece P10 that is spaced from the corresponding side wall L11 as it goes from the base end portion to the front end portion, and the first side plate piece P10 is located on the opposite side of the elastic locking claw P8. And the base end portion corresponds to the side wall L11. A second side plate portion P11 that is in contact with and extends from the base end portion to one side in the axial direction of the adapter L1 is a free end portion, and from the corresponding side wall L11 as it goes from the base end portion to the front end portion. It has the 2nd side board part P11 spaced apart.

Both the first side plate piece P10 and the second side plate piece P11 have tip portions extending from the tip portion of the elastic locking claw P8 to one side in the axial direction of the optical adapter L1.

The adapter L1 is prevented from rattling with respect to the mounting hole 110.

Thus, in the conventional adapter mounting bracket P4, the first side plate piece P10 is prevented while the optical adapter L1 is unexpectedly detached from the mounting hole 110 by the elastic locking claw P8. In addition, the elastic force of the second side plate piece P11 prevents the optical adapter L1 from rattling in the mounting hole 110, but only the tip portions of the first side plate piece P10 and the second side plate piece P11 are the mounting panel. There is a problem that it is difficult to obtain a sufficient holding elastic force because it is not engaged with the inner peripheral surface of the 100 mounting holes 110.
Further, since the structure of the adapter mounting bracket P4 is complicated, the manufacturing cost increases, and the adapter mounting bracket P4 must be attached to each of the optical adapters L1, so that the work cost increases. There was also a problem of inviting.

However, the present invention is not limited to this, and an LC type optical connector capable of individually inserting optical cables one by one into the two connector mounting holes L17 may be used.

  On the other hand, the connector mounting hole L17 of the LC type optical adapter L1 has a first space L171 for receiving the LC type optical connector main body L22 and a second space for receiving a part including the base end portion of the engagement piece L23. L172, and the second space L172 includes the engaging protrusions such that the engaging piece L23 is elastically deformed downward as the LC optical connector L2 is inserted from the outside into the first space L171. A guide surface L173 that guides L24 and is disengaged from the engaging protrusion L24 when the LC optical connector L2 is inserted to a connecting position where the ferrule L21 is inserted into the sleeve L16; An engagement surface L174 extending upward from the inner end side of the guide surface L173, and the guide surface L1 when the LC optical connector L2 is located at the coupling position. 3 and the engagement protrusion L24 are disengaged, and the engagement piece L23 is moved upward by the retained elasticity to engage with the engagement protrusion L24 to prevent the LC optical connector L2 from coming off. Engaging surface L174.

  In the configuration as described above, the LC type optical connector main body L22 of the LC type optical connector L2 is inserted into the opening end L18 of the connector mounting hole L17 of the LC type optical adapter L1 to connect them. First, the LC type optical connector L2 is positioned with respect to the LC type optical adapter L1 by inserting the LC type optical connector main body L22 into the first space L171 of the connector mounting hole L17.

The ferrule L21 is movable in the axial direction with respect to the LC optical connector L2, and is urged toward the distal end side in the axial direction. Therefore, when the first optical cable and the second optical cable are connected to the LC type optical adapter L1, the ferrules L21 come into contact with each other in a state in which the tip portions are pressed against each other. Thereby, the light transmission loss at the time of connection can be reduced as much as possible. Further, even when engaged, the engagement protrusion L24 presses the inner surface on the upper wall L12 side of the connector mounting hole L17 by the retained elasticity of the engagement piece L23, so that the position of the ferrule L21 is intentionally moved to the sleeve. Since it is biased in the state of being decentered in the direction of the bottom wall L13 within L16, the first optical cable and the second optical cable are connected at the same eccentric position. Accordingly, the ferrules L21 can be arranged at the same position without causing the axial centers of the ferrules L21 to be displaced.

  By the way, when the LC optical connector L2 is pulled out from the LC optical adapter L1, the engagement protrusion L24 and the engagement surface L174 are engaged by pressing the engagement piece L23 in the axial center direction. Since the connection is released, the LC optical connector L2 can be pulled out from the LC optical adapter L1 in this state.
