  • Patent number: 8402587
    Abstract: An optical connector cleaning tool includes a holder, cleaner, and cap. The holder includes, a cylindrical slider, a cylindrical body which is rotatable and movable in the axial direction with respect to the slider, and a slider return spring which biases the body forward to return the slider to the initial position. The slider has a pair of elastic pieces having guide projections. In the outer circumferential surface of the body, spiral grooves with which the guide projections engage are formed within the angular range of 360°. When the slider moves forward, the body rotates by the cam action of the guide projections and spiral grooves. The cleaner includes, a cleaning thread accommodated in a rotary pod, a supply reel, a take-up reel, and a cleaning pin, and is connected to the body.

  • Publication number: 20110047731
    Abstract: An optical connector clearing tool (1) includes a holder (2), cleaner (5), and cap (6). The holder (2) includes, e.g., a cylindrical slider (10), a cylindrical body (12) installed to be rotatable and movable in the axial direction with respect to the slider (10), and a slider return spring (13) which biases the body (12) forward to return the slider (10) to the initial position. The slider (10) has a pair of elastic pieces (16) having guide projections (17). In the outer circumferential surface of the body (12), spiral grooves (25, 26) with which the guide projections (17) engage are formed within the angular range of 360°. When the slider (10) moves forward, the body (12) rotates by the cam action of the guide projections (17) and spiral grooves (25, 26). The cleaner (5) includes, e.g., a cleaning thread (41) accommodated in a rotary pod (40), a supply reel (42), a take-up reel (43), and a cleaning pin (44), and is connected to the body (12).
