Description

Network cable easy pull pliers

technical field

The utility model relates to an easy-to-extract pliers for network cables.

Background technique

In the process of network operation and maintenance, it is often necessary to unplug the network cable on the switch or network adapter to troubleshoot or change the jumper. During the general working process, due to the dense network cables in the wiring cabinet, and most of the plastic shrapnel of the crystal head go deep into the network cable socket, it is difficult for fingers to touch the plastic shrapnel and exert force on it. Therefore, the operator needs both hands to complete the operation, one hand holds down the plastic shrapnel of the crystal head, and the other hand grabs the network cable to take out the crystal head. In some environments, due to the long-term effect of temperature, humidity and dust, the network cable head and the network cable socket are stuck together. This operation is more difficult to pull out the network cable, and it will cause the network cable to swing relative to the crystal head, making the contact between the inner core wire and the metal sheet of the crystal head loose. The twist distance of the wire pair is also affected, resulting in damage to the network cable.

The patent application number is "201220601023.4" and the patent application document named "a network cable head plugging pliers" introduces a network cable plugging pliers, which includes a pliers handle, a pole, and a pliers head. The metal plate is provided with a rubber pad, and the clamp handle includes a multi-section support rod. When in use, the jaws clamp the network cable, and the metal plate on the clamp head provides the clamping force to pull out the network cable. The rubber pad set on the metal plate can Prevent damage to the cable head. However, the pliers head is too short, and it does not consider the interference of many network cables bundled together on the removal work. It is only suitable for situations where the network cables are relatively small and loose, and the 4mm metal plate is suitable for the 4.5mm longitudinal socket spacing of the 48-port switch. The margin is not enough; the patent application number is "201220201150.5", and the patent application document named "Switch network cable quick disassembly tool" introduces a switch network cable disassembly tool, which includes an inverted U-shaped body, with elasticity on both sides of the body, and two sides of the body. There is a catch at the bottom of the side, and the catch protrudes toward the inner side of the bottom of the body. There is a stopper on the upper part of the inner end of the protruding part of the catch. During use, you only need to clip the special tool to the crystal head of the network cable, and apply it slightly to the crystal head of the network cable. The network cable can be released by external force, which will minimize the possibility of damage to the crystal head. However, it is still difficult to connect the card to the crystal head in dense network cables.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned problems existing in the prior art and provide an easy-to-pull pliers for network cables. , has an opening, and the size of the opening matches the thickness of the crystal head, which can clamp the crystal head for plugging and unplugging work, and avoid damage to the crystal head caused by clamping the crystal head flat due to excessive force.

The above-mentioned technical purpose of the utility model is mainly solved by the following technical solutions: the network cable easy-to-pull pliers includes two pliers petals and two pliers handles, the tails of the two pliers petals are pivotally connected to the corresponding The handles of the forceps are connected, and it is characterized in that a jaw closure limiter is set between the two petals of the forceps. When the two petals of the forceps are closed, a U-shaped cavity is formed between the two petals of the forceps. The length is between 50 mm and 100 mm, and the material of the two pincer flaps, the two pincer handles and the pivot is insulating hard rubber. Increase the length of the clamp flaps, so that the length of the clamp head composed of two flaps can be increased, and it can penetrate into the wiring cabinet with dense network cables to clamp the crystal head of the network cable. U-shaped cavity, that is, no matter whether the crystal head is clamped or not, the outer ends of the pliers can never be closed together, and there is an opening, and the size of the opening matches the thickness of the crystal head, so that the crystal head can be clamped for plugging and unplugging. Avoid clamping the crystal head with excessive force, which may cause damage to the crystal head. When the jaws are closed, the size of the opening is controlled by the jaw closure limiter.

As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: A jaw opening limiter is set between the two pliers handles, and the jaw opening limiter is a tension spring, or an elastic A rubber strip, the two ends of the jaw opening limiter are respectively fixed on the two pliers handles. The setting of the jaw opening limiter is to ensure that the pliers can smoothly withdraw from the operation area and avoid damage to surrounding objects while being able to clamp the crystal head smoothly. On the other hand, avoid over-opening the handle of the pliers, which is not conducive to one-handed operation, and requires the cooperation of both hands, which brings inconvenience to the operation.

In order to facilitate production and processing, and also to avoid damage to the network cable due to the edges and corners on the jaw closure limiter of the assembly, the jaw closure limiter is a clamp with an integral structure with the two jaws respectively. Mouth closure limiter.

The thickness of the head of the two petals is 0.5-2 mm, and the width is 4-10 mm. The inner sides of the heads of the two petals are respectively provided with fine-grain anti-skid parts, and the length of the fine-grain anti-skid parts is 7-12 mm. mm. Under the premise of ensuring the strength, this structure makes the head of the clamp valve thin enough to be easily inserted into the wiring cabinet with dense network cables to clamp the crystal head, and the fine-grained anti-slip part can generate enough friction to prevent the crystal head from detaching. Improve work efficiency.

The bottom of the U-shaped cavity is a circular arc transition part, which is beneficial to avoid damage to the network cable.

When the two pincer valves are closed, the distance between the head openings of the two pincer valves is 6.5-7.5 mm. There is a gap in the stroke of the jaws, which matches the thickness of the crystal head, so as to prevent the operator from pinching the crystal head with excessive force.

The utility model has the beneficial effects: 1. The length of the clamp flap can penetrate into the wiring cabinet with dense network cables to clamp the crystal head of the network cable. 2. When the two petals are closed, there is an opening, and the size of the opening matches the thickness of the crystal head, which can clamp the crystal head for unplugging and insertion work, and avoid damage to the crystal head caused by excessive force and flattening of the crystal head. 3. The insulating hard rubber is used to improve the operation safety. 4. The inner wall of the U-shaped cavity is smooth, and the bottom is a circular arc transition part, which is beneficial to avoid damage to the network cable. 5. On the premise of ensuring the strength, the head of the clamp valve is made thin enough to be easily inserted into the wiring cabinet with dense network cables to clamp the crystal head, and the fine-grained anti-slip part can generate enough friction to prevent the crystal head from detaching and improve work efficiency. 6. The setting of the jaw opening limiter is beneficial to avoid damage to surrounding objects, and avoid the over-opening of the jaw handle, which is convenient for one-handed operation.
