Abstract

An optical connector cleaning tool includes: a tool body; and an extension that moves relatively with respect to the tool body. The extension extends out of the tool body and includes a head that presses a cleaning element formed with a tape-like adhesive element onto an optical connector. A relative movement of the extension with respect to the tool body carries the cleaning element to the head, and after carrying the cleaning element to the head, enables the cleaning element to contact the optical connector.

First claim

The invention claimed is:

1. An optical connector cleaning tool for cleaning an optical connector, comprising:
a cleaning element comprising a tape-like adhesive element;
a tool body; and
an extension
comprising a head that presses the cleaning element onto the optical connector, wherein
by moving relatively with respect to the tool body, the extension carries the cleaning element to the head, and then stays out of the tool body to cause the cleaning element to contact the optical connector while the cleaning element is fixed with respect to the head.

2. The optical connector cleaning tool according to claim 1 , wherein
the extension further comprises a blocking part,
while the cleaning element is carried to the head, the blocking part prevents the cleaning element from contacting the optical connector, and
after the cleaning element is carried to the head, the blocking part is released and the cleaning element is enabled to contact the optical connector.

3. The optical connector cleaning tool according to claim 2 , wherein
the blocking part moves relative to the head, and
by moving relatively with respect to the head, the blocking part shifts a state of the optical connector cleaning tool from a state in which the blocking part prevents the cleaning element from contacting the optical connector to a state in which the blocking part is released and the cleaning element is enabled to contact the optical connector.

4. The optical connector cleaning tool according to claim 3 , wherein, when the cleaning element is carried to the head, an endface of the blocking part projects toward the optical connector farther than an endface of the head.

5. The optical connector cleaning tool according to claim 4 , wherein, after the cleaning element is carried to the head, the endface of the head is exposed to the optical connector when a positional relationship between the blocking part and the head is changed.

6. The optical connector cleaning tool according to claim 5 , wherein, after the cleaning element is carried to the head, the endface of the head is exposed to the optical connector when the blocking part retracts with respect to the head.

7. The optical connector cleaning tool according to claim 5 , wherein, after the cleaning element is carried to the head, the endface of the head is exposed to the optical connector when the head is moved forward with respect to the blocking part.

8. The optical connector cleaning tool according to claim 5 , further comprising:
a first spring between the tool body and the extension, wherein the first spring restores a positional relationship between the tool body and the extension; and
a second spring on a side opposite to the optical connector with respect to the blocking part, wherein the second spring restores the positional relationship between the blocking part and the head.

9. The optical connector cleaning tool according to claim 8 , wherein a load on the first spring at a time when the cleaning element to the head has been carried to the head is smaller than a load on the second spring at a time when the cleaning element is enabled to contact the optical connector.

10. A method of cleaning an optical connector by using an optical connector cleaning tool comprising a cleaning element comprising a tape-like adhesive element, a tool body, and an extension that moves relative with respect to the tool body and extends out of the tool body, wherein the extension comprises a head that presses the cleaning element onto the optical connector, the method comprising:
carrying the cleaning element to the head by moving the extension relatively with respect to the tool body; and
contacting the optical connector with the cleaning element that was carried to the head while the cleaning element is fixed with respect to the head.
