Description

  The present invention relates to an optical connector clip and an optical connector plug that hold a plurality of optical connector plugs, and an optical harness including these.

  A technique is known in which an optical connector plug provided with a ferrule is detachably connected to another member such as an adapter (see Patent Document 1). For example, as shown in FIG. 6, this type of optical connector plug 100 is disposed along the side wall of the optical connector plug 100 and includes a latch piece 103 that engages with a mating member 102 to be connected, and a latch. A displacement lever 104 for displacing the piece 103 is provided. The shape of the displacement lever 104 is formed such that the pressing surface is substantially flat.

  When the optical connector plug 100 is attached to the mating member 102, it is inserted as it is, and the displacement lever 104 is deformed to engage the latch piece 103 with the mating member 102. As a result, the optical connector plug 100 cannot be removed from the mating member 102. When the optical connector plug 100 is removed from the mating member 102, the displacement lever 104 is pushed down to release the engagement between the latch piece 103 and the mating member 102. Thereafter, the optical connector plug 100 is pulled out.

JP 2001-305392 A (FIG. 1)

  In the above-described technique, since the pressing surface of the displacement lever 104 is formed to be substantially flat, when the optical connector plug 100 is to be removed from the mating member 102 with the displacement lever 104 pressed down, The finger is slippery and the operability is not good.

  Accordingly, a main object of the present invention is to provide an optical connector clip, an optical connector plug, and an optical harness that are easy to operate at the time of removal.
