Abstract

An integrated opposite hook cable clamp includes a clamping plate, a connecting plate, and at least two J-shaped clamps. Side bars of the J-shaped clamps are locking bars. Locking holes corresponding to the locking bars are provided on the clamping plate, and at least two of the locking holes are diagonally arranged on the clamping plate. The locking bars of the J-shaped clamps vertically pass through the locking holes on the clamping plate and are movably connected with the clamping plate by a locking mechanism. A back surface of the connecting plate is lap-jointed to the inner sides of hooks of each of the J-shaped clamps. A front surface of the connecting plate is opposite to a front surface of the clamping plate (22).

Abstract

A dual-wheel cable fixing device, relating to the field of cable installation, comprising a street code support (1) and at least one pair of insulating wheels, each pair of insulating wheels comprising a first insulating wheel (11) and a second insulating wheel (12). The street code support (1) comprises a vertical pedestal (13) and at least two transverse mounting bases (14) arranged on the pedestal (13) in parallel. The second insulating wheels (12) are sleeved on one mounting base (14), separately. The first insulating wheels (11) are provided between two adjacent mounting bases (14) and pass through the mounting bases (14) by means of a vertical connecting rod (15). A first cable clamp (201) and a second cable clamp (202) which are used for fixing cables (3) are mounted on the first insulation wheel (11) and the second insulation wheel (13), respectively. According to the dual-wheel cable fixing device, a cable is fixed on an insulating wheel by means of a cable clamp so as to replace an approach of binding the cable with a binding wire. The cable sheath is not liable to damage and the fixed cable is not liable to fall off. The street code support is simultaneously provided with two groups of cable clamps so that one, two, three or four groups of cables can be fixed simultaneously. The cables are arranged compactly and space is saved.

Abstract

An integrated opposite hook cable clamp, relating to the field of cable installation. The cable clamp comprises a clamping plate (22), a connecting plate (23), and at least two J-shaped clamps (21). Side bars of the J-shaped clamps (21) are locking bars (212). Locking holes (222) corresponding to the locking bars (212) are provided on the clamping plate (22), and at least two locking holes (222) are diagonally arranged on the clamping plate (22). The locking bars (212) of the J-shaped clamps (21) vertically pass through the locking holes (222) on the clamping plate (22) and are movably connected with the clamping plate (22) by means of a locking mechanism. The back side of the connecting plate (23) is lap-jointed to the inner sides of hooks (211) of the J-shaped clamps (21). The front side of the connecting plate (23) rightly faces the clamping plate (22). The integrated opposite hook cable clamp locks and fixes a cable to a conventional cable fixing tool so as to replace a mode of binding the cable by winding a wire around the cable. The sheath of the cable is not liable to damage, can be firmly fixed and is not liable to fall off. The cable can be firmly fixed to the cable fixing tool no matter passing through the cable fixing tool straightly or in a bent way. The connecting plate (23) or the clamping plate (22) can clamp the cable in cooperation with an insulator. The cable is arranged flexibly

Abstract

A cable end fastening device comprises a cable presser (11), a movable pressing block (12) and a tightening threaded rod (13). The cable presser (11) comprises a top portion and a bottom portion arranged opposite thereto. The movable pressing block (12) is located between the top portion and the bottom portion of the cable presser (11) and is arranged opposite to the bottom portion of the cable presser (11). Cable holding structures are respectively arranged at the bottom portion of the cable presser (11) and a lower surface of the movable pressing block (12) to operate together to hold a cable. The tightening threaded rod (13) vertically passes through a threaded hole at one side of the movable pressing block (12) and is connected to the threaded hole via a thread connection. Two ends of the tightening threaded rod (13) are rotatably connected to the top portion and the bottom portion of the cable presser (11) respectively. The tightening threaded rod (13) can be employed to adjust the movable pressing block (12) to move to and fro in relation to the bottom portion of the cable presser (11). A position limiting mechanism is arranged at the cable presser (11) to limit the movable pressing block (12) and prevent the movable pressing block (12) from rotating in relation to the cable presser (11). The cable end fastening device is used to bend and tightly press a cable end of a cable wound around a ceramic insulation frame in a labor-saving and rapid manner. When in use, there is no need to move the position of the tightening tool, reducing a required operation space and operation difficulty.

Abstract

A self-locking cable fastening holder comprises a U-shaped male holder (21) and a female holder (22). A first cable holding part (211) is arranged at a bent portion of the U-shaped male holder (21). A second cable holding part (221) is arranged at the female holder (22). The first cable holding part (211) and the second cable holding part (221) can cooperate to hold a cable. Locking rods (212) are arranged at two sides of the U-shaped male holder (21), and corresponding locking holes (222) are arranged at the female holder (22). A non-return shaft (2121) is arranged at each of the locking rod (212), and a movable locking block (223) is arranged at a side each of the locking holes (222) and has a corresponding locking thread (2231). The locking block (223) abuts against a locking spring (224) such that the locking spring (224) pushes the locking block (223) against the non-return shafts (2121) of the locking rods (212), so as to limit the locking rod (212) to only move forwards and not in reverse, forming a non-return self-locking mechanism. The U-shaped male holder (21) can only move forwards, and not in reverse, in the female holder (22). When in use, the U-shaped male holder (21) is directly inserted into the female holder (22) and is automatically locked. When opening the lock, the locking spring (224) is pushed to retract the locking block (223), so as to freely remove the U-shaped male holder (21) from the female holder (22). The embodiment is simple in operation and easy to use, and is particularly suitable for use in overhead power line installation.
