Description

Safety Secondary Cable Stripper

technical field

The utility model relates to a wire stripping tool, in particular to a safe secondary cable stripper.

Background technique

In the process of wiring the secondary circuit of electrical equipment, secondary cables are usually used. In the process of laying wires and connecting equipment, it is necessary to remove part of the outer insulation layer of the secondary cable according to actual needs, and then connect the secondary wires in the insulation layer of the secondary cable according to the relevant design and connect them to related equipment. In this process, it is usually necessary to use a utility knife to cut the insulation layer of the secondary cable. There is no metal protection layer between the insulation layer of ordinary secondary cables and the secondary line (due to factors such as the high price of secondary cables with metal protection layers, increased wire diameter, increased weight, and poor heat dissipation, it is currently common The secondary cable used has no metal protective layer), therefore, when the worker cuts the insulation layer with a tool knife, if the force is too large, it is easy to scratch the secondary wire insulation under the insulation layer (affected by temperature, winter The insulation layer is hard, and the insulation layer is soft in summer), causing potential safety hazards. In addition, in the process of using a tool knife to cut the insulation layer of the secondary cable, it is usually necessary to hold the secondary cable firmly with one hand, and the other hand holds the tool knife to cut the insulation layer. hand. In such an extremely inconvenient situation, there is currently no safe and compact wire stripper that can solve such problems.

Contents of the invention

The purpose of the utility model is to provide a secondary cable that can avoid the secondary wire under the insulation layer being scratched in the process of cutting the insulation of the secondary cable, thereby causing potential safety hazards or losses caused by replacing the wire, and is low in cost and practical. safe secondary cable stripper.

The technical solution provided by the utility model is: the safety secondary cable stripper includes a handle and a cutting device, and is characterized in that: the cutting device is composed of a blade seat, an arc-shaped partition and a cutting blade. There is a blade installation groove on the bottom of the blade, the cutting blade is embedded in the blade installation groove, and its knife edge faces the outside, and the arc-shaped partition is arranged below the cutting blade in parallel, and protrudes from the edge of the knife toward one end of the knife edge; the arc-shaped The partition is fixedly connected with the handle, and the protruding arc of the curved partition faces upwards; a finger ring is arranged on the handle.

A further technical proposal of the utility model: the cross-section of the arc-shaped partition is semi-circular, and the diameter of the arc-shaped partition is equal to the diameter of the inner wall of the secondary cable insulation layer, and one side of the arc-shaped partition is provided with The threaded connecting rod is provided with a threaded connecting hole correspondingly on the side where the handle is connected with the arc-shaped partition, and the curved partition is threadedly connected with the threaded connecting hole on the handle through the threaded connecting rod.

A further technical solution of the utility model: the cutting blade is fixed in the blade installation groove by bolts.

The preferred technical solution of the utility model: the length of the curved partition protruding from the edge of the cutting blade is 1-4cm.

The preferred technical solution of the utility model: the diameter of the finger ring is 2-3cm.

The preferred technical solution of the utility model: the arc-shaped partition is made of hard plastic.

The preferred technical solution of the utility model: the length of the cutting blade is 2/3 of the length of the blade installation groove.

The utility model is simple in structure, small in size, easy to carry, and strong in safety. When the utility model is used for secondary cable cutting, the arc of the arc partition is the same as that of the inner wall of the secondary cable insulation layer, and is just embedded between the secondary cable insulation layer and the secondary wire, thus avoiding the need to cut the secondary cable. During the insulation process of the secondary cable wires, the insulation of the secondary wires under the insulation layer is scratched, resulting in potential safety hazards or losses caused by the replacement of wires.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. In Fig. 1, 2, described a kind of safe secondary cable wire stripper, comprises handle 1 and cutting device, is characterized in that: described cutting device is made up of blade seat 2, arc partition 5 and cutting blade 6, in The bottom of the blade holder 2 is provided with a blade installation groove 7, and the cutting blade 6 is embedded in the blade installation groove 7, and its edge of a knife 4 faces the outside, and the arc-shaped partition 5 is arranged below the cutting blade 6 in parallel, and faces the edge of the knife 4. One end protrudes from the edge of the knife; the arc-shaped partition 5 is fixedly connected with the handle 1, and the protruding arc-shaped surface of the arc-shaped partition 5 faces upward; a finger ring 3 is provided on the handle 1. The cross-section of the arc-shaped partition 5 is semi-circular, and the diameter of the arc-shaped partition 5 is equal to the diameter of the inner wall of the secondary cable insulation layer, which can just be embedded between the secondary cable insulation layer and the secondary wire. The two are separated; a threaded connecting rod 8 is provided on one side of the arc-shaped partition 5, and a threaded connection hole 9 is correspondingly opened on the side where the handle 1 and the arc-shaped partition 5 are connected, and the arc-shaped partition 5 is connected by threads The rod is threaded with the threaded connection hole 9 on the handle 1.

The cutting blade 6 is fixed in the blade installation groove 7 by a bolt 10, which can be easily disassembled.

The length of the curved partition 5 protruding from the edge of the cutting blade is 1-4cm. The curved partition 5 first extends into the inside of the secondary cable, and then cuts after being fixed, which is safe and improves the accuracy of operation.

The diameter of the finger ring 3 is 2-3cm. The diameter of the finger ring 3 needs to be greater than the thickness of the finger, and the finger ring 3 is to facilitate the staff to hold the wire stripper more firmly, so as to work better.

The curved partition 5 is made of stainless steel or hard plastic, and can be easily embedded in the secondary cable.

The length of the cutting blade 6 is 2/3 of the length of the blade mounting groove 7 .

When the utility model is in use, it is only necessary to first turn the edge of the cutting blade 6 outwards so that the upper and rear parts of the cutting blade 6 are close to the handle 1, and the cutting blade 6 is fixed in the blade installation groove 7 by bolts 10 to fix the cutting blade. Blade 6, according to the thickness of the secondary cable to be cut, select the appropriate arc partition 5, then align the arc partition 5 with the threaded connection hole 9 on the handle 1 through the threaded connecting rod 8, and tighten it, The wire stripper is ready to use. When stripping, hold the secondary cable firmly with one hand, hold the wire stripper with the other hand, aim at the stripping opening of the secondary cable, and slowly push the wire stripper so that the arc-shaped partition 5 extends into the secondary cable 11 Then continue to push between the outer insulating layer and the secondary line, and the cutting blade 6 will start to scratch the outer insulating layer, and judge the length of the scribed line according to the needs, which is simple and convenient to use.
