Description

Technical Field

[0001] This utility model relates to the field of optical cable suspension clamp hardware, specifically an optical cable hardware for overhead lines. Background Technology

[0002] If the optical cable is in a loose state between the two clamping fittings after being held by the suspension fittings, it cannot be adjusted. This will cause the clamped position at the suspension end to be in a bent state for a long time. At this time, the optical fiber inside the cable will be bent, which will lead to increased loss and reduced signal-to-noise ratio. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 In this embodiment of the utility model, an optical cable fitting for an overhead line includes a first rotating seat 1, a second rotating seat 2 rotatably mounted on the outer periphery of the first rotating seat 1, and an annular groove formed on the mating surface of the first rotating seat 1 and the second rotating seat 2 to wrap the outer periphery of the optical cable. The two annular grooves form a circular groove. Two mounting grooves 3 are opened on the outer periphery of the first rotating seat 1 and the second rotating seat 2. A clamping mechanism 4 is rotatably mounted on the inner wall of the mounting groove 3. A portion of the clamping mechanism 4 extends into the interior of the circular groove. The clamping mechanism 4 is connected to the first rotating seat 1 and the second rotating seat 2 through a reset mechanism.

[0017] In this embodiment: First, after the device is connected to the cable, the first rotating seat 1 and the second rotating seat 2 are rotated. At this time, the optical cable is located in the annular groove of the first rotating seat 1 and the second rotating seat 2. Through the first annular groove, the optical cable between the two devices is relatively loose. The optical cable can be moved by pulling it to avoid excessive sag between the two devices. Since the clamping mechanism 4 has a movement restriction to prevent reverse movement, it can prevent the optical cable from moving in the opposite direction, thus achieving effective clamping and keeping the optical cable between the two devices in a suitable tension state. After adjustment, it can be effectively maintained in a non-interference state.

[0018] Please refer to this carefully. Figure 1 and Figure 2 Four clamping mechanisms 4 are equidistantly distributed in the circumferential direction. Each clamping mechanism 4 includes an outer inclined plate 401, a rotating plate 402, and an inner inclined plate 403. The rotating plate 402 is rotatably installed in the middle of the inner cavity of the mounting groove 3. An outwardly protruding outer inclined plate 401 is integrally formed on the outer periphery of the rotating plate 402, and an inwardly protruding inner inclined plate 403 is integrally formed on the inner periphery of the rotating plate 402. The vertical cross-sections of the outer inclined plate 401, the rotating plate 402, and the inner inclined plate 403 form a "Z" shaped structure.

[0019] In this embodiment: when clamping the optical cable, the optical cable is placed in the circular groove, and then the first rotating seat 1 and the second rotating seat 2 are rotated and closed. Then, the bolts and nuts are tightened. After that, the degree of sag between the two devices is observed. Then, the optical cable is pulled to move in the direction where the optical cable is not clamped. At this time, the optical cable between the two devices is tightened and is in a taut state, which avoids the situation where the optical cable cannot be adjusted after the device clamps the optical cable.

[0020] Please refer to this carefully. Figure 2 and Figure 3 The reset mechanism includes receiving grooves 5 opened at both ends of the rotating plate 402. A rotating shaft 7 protruding to the outside of the rotating plate 402 is fixedly installed on one end of the inner wall of the receiving groove 5. The rotating shaft 7 is rotatably connected to the first rotating seat 1 and the second rotating seat 2. A torsion spring 6 is fixedly installed between one end of the inner wall of the receiving groove 5 and the first rotating seat 1 and the second rotating seat 2. The torsion spring 6 is sleeved on the outer periphery of the rotating shaft 7.

[0021] In this embodiment: During the clamping process of the optical cable, the lower edge ends of the inner inclined plate 403 contact and squeeze each other according to the different diameters of the optical cable. At this time, the inner inclined plate 403 drives the rotating plate 402 and the outer inclined plate 401 to rotate simultaneously. At this time, the end of the torsion spring 6 that is engaged with the rotating plate 402 rotates accordingly, while the end of the torsion spring 6 that is engaged with the first rotating seat 1 and the second rotating seat 2 remains stationary. Therefore, the torsion spring 6 has an inward restoring force after deformation, which can form an effective clamping force on the surface of the optical cable. After clamping, the optical cable can be adjusted towards the inner inclined plate 403, and the optical cable can be prevented from moving towards the outer inclined plate 401, thus achieving the adjustment effect after fixing the optical cable.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
