Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric heating tool, especially relates to a kind of anti-static wire hot stripping scissors. BACKGROUND

[0002] Hot stripping scissors, as a kind of electrician tool specially used for stripping the outer insulation layer of wire, heat the insulation layer of wire to make it soften and easy to strip. This heating method not only improves the stripping efficiency, but also reduces the damage to the internal metal conductor of wire during stripping. Compared with cutters and pliers, shearing is more suitable for precise design scenarios, and cutting can ensure that the internal metal conductor of wire is not damaged during insulation layer stripping, which helps to maintain the integrity and conductivity of wire. It is widely used in electronic manufacturing, aerospace, medical equipment, communication equipment and other fields.

[0003] The tool has very small operating space in actual use, so the space occupied by the built-in heating device, such as common electric heating wire, is also very small. Therefore, the existing shearing blade built-in single-path electric heating wire is connected to the enameled wire at one end and provides heat through the tool bit to connect with the shell at the other end to form a loop. Since the shell cannot be grounded, the anti-static effect cannot be achieved. The articulation between a pair of shearing blades and the X-shaped appearance also increase the difficulty of implementing line grounding. However, in the military and aerospace fields, such as carbon fiber and ceramic matrix composite materials, they often have high insulation, which means they are not easy to conduct electricity, thus easily accumulating static electricity. When static electricity accumulates to a certain extent, it may cause discharge, and electrostatic discharge may cause tiny cracks, deformation or contamination on the surface of the material, thereby affecting the overall performance of the product and causing damage to electronic products and equipment, and even causing fire or explosion and other serious consequences. Since the materials used in these fields often have special electrical properties, such as high insulation and static sensitivity, how to ensure effective heating of the insulation layer in a small space while preventing the hazards caused by static electricity accumulation has become a technical problem that needs to be solved.

[0020] Firstly, the anti-static wire hot stripping shear according to the embodiment of the utility model will be described, which is widely applied in the scenes of processing wire and stripping insulation layer. In the embodiment, the shearing wire is taken as an example for description. Figure 1

It also contains: a pair of heating device built-in groove 41, a pair of conduction built-in groove 42 and insulation assembly. ​

[0022] Specifically, as shown in Figure 1 the pair of heat generator built-in grooves 41, the pair of heat generator built-in grooves 41 are respectively arranged in the first shearing blade 11 and the second shearing blade 12, in each heat generator built-in groove 41, the heat generating device 5 is in double parallel 51; such design can reduce heat loss, ensure that the heat is more evenly transmitted to the shearing blade, improve the shearing efficiency and quality, and at the same time provide a circuit structure basis for loop grounding; the pair of conductor built-in grooves 42, the pair of conductor built-in grooves 42 are respectively arranged in the first shell 21 and the second shell 22, in each conductor built-in groove 42, the conducting device 6 is in double parallel 51 and is connected with the heat generator; the conducting device 6 is connected with the heat generating device 5, responsible for transmitting electric energy to the heat generating device 5, the double parallel 51 conducting device 6 can realize grounding, has the effect of preventing static electricity, enhances the stability and safety of the hot stripping process. The insulation assembly insulates the heat generating device 5 from the first shearing blade 11 and the second shearing blade 12. The existence of the insulation assembly ensures the safe isolation of the circuit, effectively preventing safety accidents caused by current leakage or short circuit.

[0023] Preferably, as shown in Figure 1 the first shell 21 and the second shell 22 are arranged in parallel with each other, the pair of heat generator built-in grooves 41 are arranged in parallel with each other, and the pair of conductor built-in grooves 42 are arranged in parallel with each other. The structure of the scissors is changed from the traditional X type to the U type design, effectively reducing the frequent physical contact and friction between the lines caused by the hinged connection, thereby greatly reducing the risk of short circuit caused by line disturbance. In addition, in terms of the pair of shells of the scissors, parallel arrangement also helps to reduce friction and resistance during operation, prolonging the service life of hot stripping.

[0024] Preferably, as shown in Figure 1 the conductor built-in groove 42 is in the shape of a strip, and the heat generator built-in groove 41 is located on the extension line of the opposite conductor built-in groove 42. The layout makes the circuit connection more compact and orderly, reducing the interference and failure risk between the lines.

[0025] Preferably, as shown in Figure 1 the plane where the first shearing blade 11 and the second shearing blade 12 are located is perpendicular to the plane where the first handle 31 and the second handle 32 are located. While ensuring the positional relationship of the heat generating device 5 and the conducting device 6 on the same straight line, the vertical arrangement of the handle directly applies force, and the user can more intuitively grasp the shearing force and direction during operation, improving the accuracy and safety of the operation.

[0026] Preferably, as shown in Figure 1As shown, a third built-in groove 43 is arranged at the joint of the opposite built-in groove 41 of the heating device and the built-in groove 42 of the conductor, and the width of the third built-in groove 43 is greater than the width of the built-in groove 41 of the heating device and the built-in groove 42 of the conductor. The position is used to place the connecting solder joints of the heating device 5 and the conductor assembly, which effectively avoids the short circuit caused by the contact of the solder joints; in addition, the additional space is also used for heat dissipation at the solder joints, which enhances the reliability and stability of the thermal stripping.

[0027] Preferably, the heating device 5 is an electric heating wire. The electric heating wire has the advantages of fast heating speed, high efficiency and low cost. At the same time, the electric heating wire also has good flexibility and plasticity, which is convenient for complex wiring inside the thermal stripping.

[0028] Preferably, as shown, Figure 1 In addition to the parallel double electric heating wires 51 in the built-in groove 41 of the heating device, a single electric heating wire 52 is also arranged. Under the premise of reaching the required power, the additional electric heating wire can effectively reduce the heat loss of the thermal stripping and prolong the service life.

[0029] Preferably, the insulation assembly includes insulation paint, which is in a flowing state and fixes the heating device 5 after air drying. The insulation paint can be evenly applied to the heating device 5 to form an insulation layer, effectively insulating the circuit conductor and improving the insulation performance of the equipment. After air drying, the insulation paint can fix the heating device 5, making it more stably installed in the built-in groove 41 of the heating device, reducing the risk of loosening or damage caused by vibration or impact.

[0030] Preferably, the insulation paint is vulcanized silicone rubber, silicone resin glue or epoxy resin glue. The above insulation glue can be in a flowing state, allowing the heating device 5 to be suspended in the built-in groove 41 of the heating device, and after air drying, the heating device 5 is insulated from the shear blade. At the same time, the above glue has good high-temperature resistance and chemical corrosion resistance, which is suitable for the high-temperature working environment of the thermal shear.

[0031] During operation, once the heating device (such as an electric heating wire) in the thermal shear equipment is powered on, heat will be generated, which is transmitted to the position of the shear blade by heat conduction mechanism, making it warm up to a degree that can effectively cut or process the insulation layer of the wire. Under this condition, the shear blade can effectively shear without damaging the internal metal. In addition, the built-in insulation component plays a key role in protecting the circuit, which ensures that the current does not flow directly through the shear blade, thereby avoiding the risk of short circuit or electric shock.

[0032] The above, with reference to Figure 1The heat stripping shears for anti-static wire are described according to the embodiments of the utility model, through the design of embedding double-path 51 heating devices 5 in the inside of the shearing blade, the traditional method of forming a loop by relying on the shell is successfully abandoned, and the risk of static accumulation is fundamentally reduced. The shell is no longer a necessary part of the current loop, further, the entire loop is grounded, the anti-static effect is achieved, which not only significantly improves the safety factor of the operation process, but also ensures the high reliability of the product, especially for those high-precision military and aerospace products processing which are extremely sensitive in the static environment, this technical improvement is crucial. In addition, in order to effectively reduce the disturbance between the circuits, the structure of the scissors is also optimized, from the traditional X type to the U type design. Although the force of the operator increases slightly, but in the actual operation scene, the absolute value of the increase is very limited, and key, this change effectively reduces the frequent physical contact and friction between the lines due to the hinged connection, thereby greatly reducing the short circuit risk caused by the line disturbance, and significantly improving the service life of the product.
