Description

Special wire stripper for cable core

technical field

The utility model relates to a cable core stripper, in particular to a special cable core stripper for cables with a specification of 4×2.5.

Background technique

The cable with a specification of 4×2.5 is the most commonly used cable in the secondary cable. The stripping of the cable core is mainly realized by ordinary wire strippers. Common wire strippers mainly have the following disadvantages: 1. The stripping accuracy is low, and the stripping 2. The copper wire is easy to be damaged during the stripping process. Once the copper wire is damaged, it is easy to break during use, causing the protection device to malfunction or 3. The four wire cores can only be stripped one by one, resulting in slow stripping speed.

Utility model content

According to the deficiencies of the prior art above, the technical problem to be solved by the utility model is: provide a special wire stripper for cable cores, which has a simple structure and a reasonable design, prevents copper wires from being damaged during the stripping process, and has a fast stripping speed. The stripping process is smooth and easy to use.

The cable core special wire stripper described in the utility model includes a left handle and a right handle, the left handle and the right handle are hinged through a pin shaft, the left handle and the right handle are made of high-strength resin material, the ends of the left handle and the right handle are Both are connected to a metal arm by bolts, and the front end of the metal arm is provided with symmetrically distributed stripping knives. The joints of the handle, the right handle and the metal arm are all crimped with a guide piece, wherein the guide piece at the left handle is connected with the ringing device arranged on the side of the left handle and the battery arranged at the lower end of the left handle through wires, and the right handle The leads are connected to the battery.

The left handle and right handle made of high-strength resin have good insulation performance. The positive and negative electrodes of the battery are respectively connected to the two metal arms through the guide plate. During the stripping process, the blade cuts the insulation layer of the cable and touches the inner part When the copper wire is connected, the ringing device will sound a reminder, so as to avoid continuous cutting of the copper wire and avoid damage to the copper wire. By setting four sets of relative blades, it can simultaneously strip the four wire cores of the 4*2.5 specification cable at the same time, rapidly increasing the stripping speed, and easy to use.

The sounding device includes a buzzer and an LED light, and simultaneously performs an audible and visual alarm.

The material of the blade is copper, and copper is used as the blade to prevent the blade from being too hard and damage the copper wire, and at the same time ensure the sharpness of the blade to facilitate cutting of the insulating layer.

The pin joint of the left handle is provided with a left shell, and the pin joint of the right handle is provided with a right shell. There is a ratchet on the shell, an internal gear is fixed on the right side of the ratchet wheel, and external teeth are set on the outside of the internal gear; a square hole is set in the center of the right shell, and a square rod is set on the pin shaft in the square hole, and a square rod is set on the left end of the square rod. The external gear is provided with internal teeth cooperating with the internal gear inside the external gear. A driving lever is fixed on the upper side of the square rod. The corresponding right housing is provided with a movable groove, and the upper end of the driving rod is arranged on the outside of the right housing. Turn the lever inward to make the outer gear and the inner gear snap together. At this time, the square rod cannot rotate under the restriction of the square hole in the right shell, so that the ratchet is fixed and cannot rotate. At this time, the left handle and the right handle are snapped together. The pawl on the left shell cooperates with the ratchet wheel to gradually lock the left handle and the right handle. When the ringing device reminds, stop using force. At this time, the left handle and the right handle are maintained in the corresponding lock under the action of the ratchet pawl position, pull the stripping knife outward to complete the stripping work. Toggle the lever outward, the outer gear and the inner gear are separated, at this moment, the ratchet can rotate freely, and the left handle and the right handle can be reset.

When in use, place the four wire cores on the four groups of blades in turn, and move the lever inward to engage the outer gear with the inner gear to limit the rotation of the ratchet, and forcefully engage the left and right handles. When the two blades of the blade both cut through the insulating layer and connect with the copper wire, the sounding device connects with the battery through the guide piece, and an audible and visual alarm is given. , Keep the right handle in the original position, pull the stripping knife outward, cut off the insulation layer, and complete the stripping process, move the lever outward to separate the external gear from the internal gear. At this time, the ratchet can rotate freely, and the The left handle and the right handle can be reset.

Compared with the prior art, the utility model has the beneficial effects of:

The special wire stripper for cable cores can be set to sound reminders by setting the ringing device, so as to avoid excessive force and prevent copper wires from being damaged; by setting four sets of opposite blades, it can strip the four cores of the 4*2.5 specification cable at the same time , to increase the stripping speed; by setting the ratchet and pawl to cooperate, the left handle and the right handle are automatically locked, which is convenient to use.
