- FIGS. 6A and 6D show the state of the front surface of the lens plate 62 of the ferrule 60 at each time point.
- the cleaning body 1 is hung around the head portion 12.
- the head portion 12 is not provided with the protruding portion 22, and there is no member protruding from the head body side pressing surface 36 of the head portion 12. Therefore, the cleaning body 1 hung around the head portion 12 has a larger curvature of the cleaning body 1 at the tip portion of the head portion 12 than the cleaning tool 10 of the first embodiment.
- dust 5 is attached to the inner surface 65 of the recess 63 of the lens plate 62 (ferrule 60). If the dust 5 adheres to the inner surface 65 in this way, it may cause an increase in connection loss. Therefore, it is necessary to remove the dust 5 with the cleaning tool 10.
- the cleaning body 1 at the tip portion of the head portion 12 comes into contact with the lens plate 62, as shown in FIG. 6B.
- the cleaning tool 10 of the comparative example has a larger curvature of the cleaning body 1 at the tip portion of the head portion 12 than the cleaning tool 10 of the first embodiment. May come into contact with the edge 65B before it comes into contact with the inner surface 65. Then, as shown in FIG. 6B, the air 6 is confined between the cleaning body 1 and the inner surface 65 of the recess 63. Even if the operator tries to further move the head portion 12 (cleaning tool 10) from this state to the lens plate 62 side, as shown in FIG. 6C, the cleaning body 1 is moved to the inner surface 65 of the recess 63 due to the presence of air 6. It will not be possible to press it on the entire area of.
- the dust 5 adhering to the vicinity of the upper end of the inner surface 65 of the recess 63 and the vicinity of the lower end of the inner surface 65 of the recess 63 is not attracted to the contact surface 2 side, and the dust 5 is on the inner surface 65 of the recess 63. It remains in. That is, as shown in the figure on the right side of FIG. 6D, the cleaning range 3 may be narrowed in the cleaning tool 10 of the comparative example.
- FIGS. 7A and 7D show the state of the front surface of the lens plate 62 of the ferrule 60 at each time point.
- the cleaning body 1 is hung around the head portion 12.
- the head portion 12 has a head main body 21 and a protruding portion 22 protruding from the head main body 21.
- the cleaning body 1 hung around the head portion 12 has a tip of the head portion 12 as compared with the cleaning tool 10 of the comparative example only in the height portion of the protruding portion 22 protruding from the head body side pressing surface 36 of the head body 21.
- the curvature of the cleaning body 1 in the portion is small.
- the cleaning body 1 at the tip portion of the head portion 12 comes into contact with the lens plate 62, as shown in FIG. 7B.
- the cleaning tool 10 of the first embodiment has a smaller curvature of the cleaning body 1 at the tip portion of the head portion 12 than the cleaning tool 10 of the comparative example, so that the cleaning body 1 First contacts the central portion of the inner surface 65 of the recess 63 in the vertical direction, and does not contact the edge 65B. Then, as shown in FIG. 7B, the air 6 is suppressed from being trapped between the cleaning body 1 and the inner surface 65 of the recess 63.
- the cleaning body 1 is pressed against the inner surface 65 of the recess 63 by the protrusion-side pressing surface 37 of the protrusion 22.
- the cleaning body 1 only contacts the central portion of the inner surface 65 of the recess 63 in the vertical direction, and is located near the upper end of the inner surface 65 of the recess 63 or near the lower end of the inner surface 65 of the recess 63. The cleaning body 1 has not yet touched.
- the protruding portion 22 When the operator further moves the head portion 12 (cleaning tool 10) toward the lens plate 62 from the state shown in FIG. 7B, the protruding portion 22 in contact with the inner surface 65 of the recess 63 moves rearward from the inner surface 65 of the recess 63. Under the pressing pressure of. As described above, since the protruding portion 22 is movable with respect to the head main body 21, the protruding portion 22 retracts with respect to the head main body 21 due to the pressing force received from the inner surface 65 side of the recess 63 (protruding portion). 22 moves in the direction opposite to the protruding direction). At this time, the protruding portion 22 retracts against the elastic force of the protruding portion spring 27. In the present embodiment, the elastic force of the head spring 26 is stronger than the elastic force of the projecting spring 27. Therefore, the projecting spring 27 precedes the head spring 26 shown in FIG. Will be compressed.
- the cleaning body 1 is pressed against the inner surface 65 by the head body side pressing surface 36 of the head body 21 that has advanced with respect to the protruding portion 22.
- the cleaning body 1 is already in contact with the vertical center portion of the inner surface 65 of the recess 63 by the protruding portion side pressing surface 37, and sequentially contacts the inner surface 65 of the recess 63 in the upward and downward directions. I will go. Therefore, it is possible to prevent the air 6 from being trapped between the cleaning body 1 and the inner surface 65 of the recess 63.
- the air 6 is suppressed from being trapped between the cleaning body 1 and the inner surface 65 of the recess 63. Therefore, as shown in FIG. 7C, the cleaning body 1 is placed over the entire area 65 of the inner surface 65 of the recess 63. Can be pressed against.
