Abstract

An electrical wire opening clipper comprises a telescopic knife and a clamp for retaining insulated conductors along a radial direction, which is characterized in that: the out-stretching knifepoint of the hilt of the telescopic knife is arranged on the clamp and the knifepoint of the telescopic knife can be stretched into the grip of the clamp. The insulated conductors are fixed by using the grip formed by the clamp, so the insulated conductors making no radial movement in the clamp channel but only making axial movement along the clamp channel when the insulated conductors are pulled by an external force. By using the knifepoint arranged on the clamp to act on the insulation layers of the insulated conductors which are fixed along the radial direction, when the insulated conductors are pulled along an axial direction and passing by the grip, relative movement happens between the knifepoint that inserted into the insulation layers of the insulated conductors and the conductors, and the knifepoint regularly exscinds the insulation layers of the insulated conductors which makes axial movement. The electrical wire opening clipper has scientific design, simple and reasonable structure, simple operation, high working efficiency and is convenient for use.

Description

The electric wire open cutting device

Technical field

The utility model relates to a kind of cutter, especially a kind of electric wire open cutting device that is used for various insulated conductors.

Technical background

At present, peeling off of the insulating barrier of various insulated conductors still do not have a kind of easy to operate specialist tools.Electrician or electric wire recovery personnel still adopt traditional electrician's knife when being used on carrying out insulated conductor insulation displacement.Electrician's knife is by cutter with forming, and is similar to general fruit knife, but it is owing to the object difference of using, and the edge of a knife is very sharp.During use, the operator hands electrician's knife, utilizes the sharp edge of a knife will be wrapped in irregular the peeling off of insulating barrier on the metal wire rod.Its inconvenient operation, work efficiency is low, and dangerous.Operating personnel often have by the accident of knife wound and hand takes place.

Summary of the invention

The purpose of this utility model is the deficiency at above-mentioned existence, and a kind of electric wire open cutting device of can be conveniently the insulating barrier of insulated conductor rule from the metal wire rod being peeled off is provided.

The utility model electric wire open cutting device comprises: flexible cutter, and it is characterized in that: one is used for the radially anchor clamps of clamping of insulated conductor; The point of a knife external part of the hilt of described flexible cutter is vertically mounted on the anchor clamps, and the point of a knife of flexible cutter can stretch into the folder mouth of anchor clamps.

The design principle of the utility model electric wire open cutting device is: the folder mouth fixed insulation lead that utilizes anchor clamps to form, and insulated conductor can not be moved radially in the anchor clamps passage, when external force pulling insulated conductor, insulated conductor can only be along the axial motion of anchor clamps passage.Utilization is installed in the insulating barrier that point of a knife on the anchor clamps acts on the insulated conductor that radially is fixed, and point of a knife inserts the degree of depth of insulated conductor can be according to the thickness adjusted of insulating barrier.When insulated conductor is axially spurred in the anchor clamps folder mouth, relative motion takes place between the point of a knife of insertion insulated conductor insulating barrier and lead, point of a knife is severed the insulating barrier of axially movable insulated conductor regularly.

The utility model electric wire open cutting device design science, simple and reasonable for structure, simple to operate, easy to use, high efficiency.Because the point of a knife of open cutting device is hidden in the anchor clamps passage, hand that can the operating of contacts person, fail safe improves greatly; Because the insulating barrier behind the stripping metal wire rod is a monoblock, can not cause the pollution of environment, and make things convenient for the recycling of insulating barrier.

The concrete structure of the utility model electric wire open cutting device is provided in detail by the following drawings and embodiment.
