(54) DEVICE FOR REMOVAL OF INSULATION FROM WIRE ENDS

The main technology of the company to technologists: equipment for the preparation of electrical wires for installation and can be used by us in the field of radio communication equipment.

A device is known for removing aa 1SchI from the wires, to keep it sneaky, moved inside the pipe with the help of a carriage, and a spring between the stationary heads & 1.

A disadvantage of the known device is that in order to melt and isolate the insulation around the perimeter, it is necessary to manually rotate the wire. In addition, the filament is possible due to mechanical loads caused by the insulation of the wire; , -

The closest to the technical essence is the tool for stripping insulation from the ends of the Wires, containing two hinged arms connected between each other, on the hinge. Two-sided p & ptarii.

However, this tool does not opytnecTvolves circular circular insulation. When working with it, it is necessary to rotate the wire with your hand or to apply additional manual force to break the non-cut part of the insulation when pulling it out. wires from the tool, which leads, ultimately, to a lower quality of wire processing.

The purpose of the invention is to improve the quality of wire processing.

This goal is achieved by

10 that the device is provided with two forks, each of which is mounted on the handle so that it can be rotated into opposite sides relative to one another; at the same time, the axes of rotation are located along the axis of the tool, and the two shoulders are pivotally mounted in the slots of the forks.

FIG. 1 shows the device, a general view; FIG. 2 is a view lio of arrow 20 ke A in FIG. 1, in FIG. 3.- a section in FIG. one; FIG. 4 shows a section B-B in FIG. 1 in fig. 5 is a schematic diagram of the operation of the sponge lips; FIG. 6 diagram of the filament.

The device for removing insulation from the ends of the wires contains two pivotally interconnected If handles held together in divorced position (spring position 2 (Fig. 1). 30 At the end of the amp x the arm is pivotally secured with the fingers 3 (Fig. 4 4) pivotally connected to two shoulders ryochag 5. The latter have a filament binder for cutting the insulation and clamping jaws 7, which are made in one piece with the levers. 5 together with forks 4 are spring-loaded springs 8, about Squeezing hands when connecting the handle to the wire of the filament. the wires are working with them; the sharpnesses are made with notches in the longitudinal and transverse directions. The adjusting screw 9 serves as a stop for the final position of the handle. The device works as follows. The end 6 of the treated wires is inserted between the sponges and the filaments. Then the hand knobs are folded down. When approaching them in the first herd, the filaments contact with the wire and the insulation melts. However, since the filaments do not form a closed loop (Fig. 2), insulation does not melt around the entire perimeter of the wire. In the second stage, the clamping jaws clamp the wire, which causes the forces of the P L FIG. five). The force P acting on the clamping jaws from the wire and arising as a reaction to the shear force of the hand causes the appearance of multidirectional torques acting on the clamping jaws and the Pt g dei E é - the shoulder of the application of force R. reaches a value dp to overcome the forces of friction and elasticity of the spring. Under the influence of the torque generated by this force, the clamping jaws rotate an angle a, and the clamped wire expands around the perimeter, respectively, for a distance h until the handle stops against the adjusting screw. Together with the clamping lips, the filaments (Fig. 6) are also rotated by an angle o (opposite to the direction of rolling), which increases the rolling length. While holding the handles in the flattened position, the wire is pulled out of the jaws, while taking away the jaws with it, it turns the levers and the threads of the poke away from the wire, respectively. The intact end of the wire is removed from the clamped insulation. The effect1) of the device lies in the convenience of operation and improving the quality of wire processing, since circular insulation is provided without additional manual turning of the wire, which eliminates the presence of uncut insulation sections.
