Technical Problem

[0005]本发明的目的在于提供一种输电线路避雷器专业线夹，以解决上述背景技术中提出的采用了最常见的螺栓连接的方式对线缆进行固定夹紧，由于热膨胀、震动、外力等因素的影响，螺栓可能会逐渐松动，这会导致避雷器与电力线路之间的接触不良，进而影响电气性能，甚至可能导致电气故障的问题

Benefits of technology

[0019] 1. When clamping cables, the bidirectional threaded rod rotates, causing the linkage column and ratchet locking ring to rotate synchronously. The clamping teeth, under the action of the torsion spring, embed into the groove of the ratchet locking ring, restricting its reverse rotation. This mechanically prevents the bidirectional threaded rod from reversing. After clamping, the position of the clamping teeth is fixed by the plug pin, forming a double fixation of ratchet unidirectional lock and plug pin fixation. This design eliminates the risk of loosening, ensuring that the surge arrester and the transmission line always maintain a stable connection, avoiding electrical faults such as overheating and discharge caused by poor contact. In addition, when releasing the clamp, it is only necessary to pull out the locking block so that the linkage column can rotate freely relative to the ratchet locking ring. There is no need to move the clamping teeth to make the ratchet locking ring rotate in the opposite direction. The ratchet locking ring only participates in the work when locking and does not intervene when releasing. This means that there will be no interference from ratchet jamming or other problems during the unlocking process. This reduces the risk of failure or damage caused by ratchet or locking ring jamming, and increases the stability and reliability of the system.

Abstract

The application discloses a power transmission line lightning arrester professional wire clamp and relates to the technical field of cable wire clamps.The wire clamp main body is provided with a mounting groove in the upper portion, a bidirectional screw rod is rotatably connected to the middle position in the interior of the mounting groove through a deep groove ball bearing, an anti-loosening assembly is arranged at the right end of the bidirectional screw rod, and a locking hole is arranged at the position of the anti-loosening assembly on the right side of the wire clamp main body.The anti-loosening assembly comprises a linkage column and a fixing rod, the linkage column is fixedly connected to the right end of the bidirectional screw rod, the fixing rod is fixedly connected to the rear right side of the wire clamp main body, a ratchet locking ring is rotatably connected to the outer side of the linkage column, a clamping tooth is rotatably connected to the right end of the fixing rod through a torsional spring, and the end, away from the fixing rod, of the clamping tooth is triangular and extends into the tooth groove of the ratchet locking ring.The advantages are that the ratchet one-way lock and the double fixing of the plug-in pin are fixed in a double way, the design eliminates the loosening risk, and the lightning arrester and the power transmission line are always kept in stable connection.
