Description

Technical Field

[0001] This utility model relates to the field of crimping pliers technology, specifically a cable connector crimping pliers. Background Technology

[0002] Crimping pliers are essential tools in the power industry for crimping conductors during basic line construction and line maintenance.

[0003] For example, announcement number CN217934529U (named "A Cable Crimping Pliers") includes a crimping pliers body and a housing. One end of the crimping pliers body is equipped with a lever. One end of the housing is connected to the crimping pliers body. A screw is rotatably mounted inside the housing. A threaded sleeve is threaded onto the surface of the screw. A pull rod is hinged to the threaded sleeve. The other end of the pull rod is hinged to the lever. A rotating component is mounted on the housing. One end of the screw is connected to the rotating component. Two levers and two pull rods are provided, symmetrically arranged. Each lever corresponds to one pull rod. By pulling simultaneously from both sides, the force is evenly distributed, avoiding uneven force distribution. The uneven friction caused by the screw is addressed by a rotating component mounted on the housing, with a screw rotatably mounted inside. One end of the screw is connected to the rotating component, which drives the screw to rotate. A threaded sleeve is threaded onto the screw surface, causing the threaded sleeve to move. A pull rod is hinged to the threaded sleeve, and the other end of the pull rod is hinged to a lever. This causes the threaded sleeve to push the pull rod, which in turn pushes the lever. The lever then connects to the pull rod at its end, replacing the traditional handle pressing operation. This allows for the clamping of cables and cable connectors without repeated manual pressing, reducing worker arm fatigue. Furthermore, the number of rotations of the screw in both directions allows for precise control of the clamping force, further reducing fatigue and minimizing rest periods, thus improving work efficiency.

[0004] The aforementioned crimping pliers use a pull rod structure instead of a lever structure for labor-saving crimping operations. However, manual crimping is inefficient, and the deformation can only be compressed once during the crimping process, resulting in poor crimping strength. To address this, we provide a cable connector crimping pliers. Utility Model Content

[0005] The purpose of this utility model is to provide a cable connector crimping pliers to solve the problem mentioned in the background art that the existing crimping pliers use a pull rod structure instead of a lever structure to perform labor-saving crimping operations, but the manual crimping efficiency is low, and the crimping process can only be compressed and deformed once, resulting in poor crimping firmness.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable connector crimping pliers, including a main clamp seat, a top platform seat provided directly above the main clamp seat, a telescopic hydraulic cylinder provided at the upper end of the top platform seat, and a central loading groove provided inside the main clamp seat;

[0007] Also includes:

[0008] The first clamp plate and the second clamp plate are disposed inside the central loading groove, and the first clamp plate and the second clamp plate are provided with a first pressing groove and a second pressing groove on their outer edges, and a gap groove is provided between the first pressing groove and the second pressing groove.

[0009] A through slot is provided at the center of the top platform. The piston rod of the telescopic hydraulic cylinder passes through the through slot and extends to the outside of the top platform. A lower pressure plate is welded to one end of the piston rod of the telescopic hydraulic cylinder.

[0010] Preferably, guide grooves are provided on both outer walls of the central loading groove, and two limiting sliders are movably arranged inside each of the two guide grooves. The four limiting sliders are arranged in pairs and are integrated with the first clamp plate and the second clamp plate respectively.

[0011] Preferably, an inner roller is movably disposed in the internal groove of the limiting slider via a bearing and a connecting shaft, and the limiting slider is rolledly connected to the guide groove via the inner roller.

[0012] Preferably, two adjacent first crimping grooves and two adjacent second crimping grooves are located on the same horizontal line, and the telescopic hydraulic cylinder abuts against the top of the second clamping plate through the lower pressure plate.

[0013] Preferably, handle blocks are provided on the front and rear outer walls of the first and second clamping plates, and the handle blocks are integral with the first and second clamping plates.

[0014] Preferably, two support rods are provided between the main clamp seat and the top platform seat, and the two ends of the two support rods are welded to the main clamp seat and the top platform seat respectively.

[0015] Preferably, gripping handles are provided on both outer walls of the main clamp seat, and both ends of the gripping handles are welded to the outer wall of the main clamp seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention utilizes a telescopic hydraulic cylinder to drive the lower pressure plate downwards, saving manpower and improving efficiency. After the lower pressure plate abuts against the upper end of the second clamping plate, it drives the second clamping plate to press down, thereby crimping the cable connector between two adjacent first crimping grooves and two adjacent second crimping grooves into two clamping rings. Compared to the single clamping ring of traditional crimping pliers, this improves the firmness of the cable connector crimping. It overcomes the problem that existing crimping pliers use a pull rod structure instead of a lever structure for labor-saving crimping operations, but the manual crimping efficiency is low, and the crimping deformation can only be performed once, resulting in poor crimping firmness.
