Description

Technical Field

[0001] The invention relates to the electrical field, in particular to a novel elbow-type cable terminal head operating rod. Background Art

[0002] With the rapid development of the economy, urban construction is changing with each passing day. Modern urban design has completely eliminated the original overhead lines and poles, replacing them with cables, ring network cabinets, box transformers and cable branch boxes. With the continuous increase of these devices, the operation frequency is also getting higher and higher.

[0003] For the elbow type cable terminal, we must use the operating lever to pull out the elbow. The operation process is complicated and cumbersome. It is affected by the weight of the cable, unstable, unsafe, and requires a high level of skill from the operator. Summary of the invention

[0010] The driving assembly is fixedly connected to the other end of the insulating sleeve and is used to drive the pull rod to move along the insulating sleeve. By setting the expansion part, the fixation is more secure during the actual operation, reducing the problems such as slipping caused by the clamp being not secure enough during the operation, greatly increasing the safety of the operation, and setting the slide groove to connect the chuck to the pull rod through the connecting rod structure, so that the pull of the pull rod can quickly tighten the chuck.

[0011] Furthermore, the driving assembly includes a base, which is fixedly connected to the insulating sleeve, and the base is provided with a through hole along the axial direction of the insulating sleeve for the pull rod to pass through, and the base is provided with a partition plate to divide the base into two sections laterally, and a trigger, a shift block, and a compression spring are provided along the axial direction of the base in a section of the base close to the insulating sleeve, and the trigger is hingedly fixed to the base, and the shift block is sleeved on the pull rod, and the two ends of the compression spring are respectively pressed against the shift block and the partition plate, and a limit stop rod is fixed on the trigger, and when the trigger is moved, the limit stop rod can force the shift block The upper part tilts toward the insulating sleeve to lock the pull rod and drive the pull rod to pull out the insulating sleeve. A locking plate and a locking spring are provided in a section of the base away from the insulating sleeve. The locking plate and the locking spring are both sleeved on the pull rod. The locking spring is axially arranged between the locking plate and the wall away from the insulating sleeve. The two ends of the locking spring respectively press against the locking plate and the wall away from the insulating sleeve. A limit block is provided on the inner wall of the base above the locking plate. Under the joint action of the locking spring and the limit block, the upper part of the locking plate tilts toward the side away from the insulating sleeve to lock the pull rod. By setting a driving component that can drive the pull rod to move in one direction, the pull rod can be pulled by pressing the trigger by hand, so that the chuck closes and clamps the elbow-shaped cable end. The pull rod is locked by the locking plate so that the pull rod remains in place after being pulled into place, so that the chuck will not open again after closing.
