Folding storage type optical fiber cleaning device

The present invention relates to a fiber cleaning device, and more particularly to an optical fiber cleaning device that adopts a fiber cleaning tape folding storage mode.

In order to ensure that the fiber is affected by foreign matter through the fiber connector assembly connector, the fiber connector must be cleaned by a fiber cleaning device before the fiber connector is connected to the connector.

At present, the structure of the conventional optical fiber cleaning device mainly comprises a fiber cleaning tape wound by a long strip of optical fiber cleaning tape, which is installed in a housing space of a casing, and is also installed in the casing. A rotating take-up mechanism is coupled to the end of the fiber cleaning belt. The user can rotate the rotating retracting mechanism to pull the unused fiber cleaning belt section to the cleaning port of the casing, and provide the user to wipe the fiber optic connector on the fiber cleaning tape exposed outside the cleaning port. The used fiber cleaning belt section is transferred to a storage space in the casing by the rotary retracting mechanism. The accommodating space and the accommodating space inside the casing are independent spaces, and the used fiber cleaning belt section is prevented from contaminating the unused fiber cleaning tape in the fiber cleaning tape roll.

However, the optical fiber cleaning device disclosed above still provides an easy-to-use optical fiber cleaning device for the user. However, the housing space and the storage space in the casing of the optical fiber cleaning device are independent spaces, and cannot mutually mutually exist. Since the size of the accommodating space and the accommodating space must each be sufficient to provide the volume of the fiber cleaning tape roll, that is, at least twice the fiber cleaning tape roll volume must be provided inside the casing. Therefore, the existing optical fiber cleaning device has a storage space that cannot be changed. The length of the optical fiber cleaning tape has a certain limit, and a large amount of the optical fiber cleaning tape cannot be installed to provide the optical fiber connector for wiping and cleaning. Therefore, the existing optical fiber cleaning device exists. The problem of less use.

In addition to the previously disclosed problems, existing fiber cleaning devices also have the problem of wasting materials because they use a rotating retracting mechanism to provide user rotation to move unused fiber cleaning belt segments to the cleaning port of the casing during operation. In the user, it is difficult for the user to control the length at which the rotating retracting mechanism drives the optical fiber cleaning belt to move to the cleaning opening of the casing. If the rotating retracting mechanism drives the optical fiber cleaning belt to have insufficient moving length, some of the used optical fiber cleaning tape segments are still located at the cleaning opening, which is disadvantageous for the user to clean the optical fiber connector; if the rotating retracting mechanism drives the optical fiber If the moving length of the cleaning tape is too long, the optical fiber cleaning tape cannot be fully utilized, and there is a problem of wasted material.

The main purpose of the present invention is to provide a folding and accommodating optical fiber cleaning device, which solves the problem that the existing optical fiber cleaning device has separate spaces for the accommodating space and the storage space in the casing, and cannot be mutually shared, so that a certain size of the casing The volume of the optical fiber cleaning tape that can be installed is limited and has a small number of uses.
