Description

Technical Field

[0001] This utility model relates to the field of electric heat tracing technology, and in particular to an electric heat tracing cable that is easy to install. Background Technology

[0002] Existing easy-to-install electric heating cables all have tear-off ropes and tear positioning holes on the surface of the insulating outer sheath. By pulling the tear-off rope in the direction of the tear positioning holes, the insulating outer sheath can be quickly peeled off. However, the insulating outer sheath can only be torn along the positioning holes and cannot be cut to the required length. For example, an easy-to-install electric heating cable disclosed in Chinese Patent Application No. CN202223332600.7, although it has a no-cut rope and disassembly positioning holes on both sides of the insulation layer, which makes it easy to peel off and remove the outer layer without tools, and the electric heating cable can be fixed with a fixing clip, still cannot easily cut off the outer layer. Moreover, the fixing effect of the fixing clip is limited and it cannot be fixed to objects that cannot be clamped, thus limiting its use. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an electric heating cable that is easy to install. By using a sliding positioning block to drive the punching nail to punch positioning holes at any position of the insulating outer sheath, the insulating outer sheath can be easily cut off by the positioning holes and the tear-through holes, which improves the convenience of electric heating cable installation. At the same time, the sliding block can slide on the insulating outer sheath, and the insulating outer sheath can be effectively fixed by the adhesive layer. When the adhesive layer fails, the connecting plate can be replaced, so that the electric heating cable can be reused.

[0004] This utility model also provides an electric heating tape with the above-mentioned easy-to-installation feature, comprising: an insulating outer sheath, a fixing component provided on the side surface of the insulating outer sheath, a tear-aiding through hole provided on the side surface of the insulating outer sheath, a protective rope fixedly connected to the inner side wall of the insulating outer sheath, a metal shielding mesh fixedly connected to the inner side wall of the insulating outer sheath, and an adjustable heat-conducting layer fixedly connected to the inner side wall of the metal shielding mesh.

With these components, the insulating outer sheath can be drilled at a designed position using the punching pin, allowing the insulating outer sheath to be cut at any location. This improves the convenience of installing the electric heating cable and enhances the fixing effect by using fixing components to secure the electric heating cable.

[0006] According to the present invention, an easy-to-install electric heating cable is characterized in that the fixing component includes a sliding block, and the lower surface of the sliding block is provided with a slot.

These components allow the locking block to engage with the slot, fixing the connecting plate and the sliding block together. The adhesive layer then adheres to the area requiring fixation, effectively securing the electric heating cable.

[0008] According to the present invention, an easy-to-install electric heating tape includes a sliding block whose inner surface is slidably connected to an insulating outer sheath, and a locking block whose side surface is fixedly connected to the sliding block inside a locking groove during operation. These components allow the sliding block to slide on the surface of the insulating outer sheath, facilitating adjustment and fixing of its position.

[0009] According to the present invention, an easy-to-install electric heating tape includes a positioning hole on the side surface of the insulating outer sheath. The end of the punching pin away from the pressing block extends through the upper surface of the positioning block into the interior of the insulating outer sheath. Using these components, a positioning hole can be punched at the location where the insulating outer sheath needs to be cut, facilitating the cutting of the insulating outer sheath.

[0010] According to the present invention, an easy-to-install electric heating cable is provided, wherein the insulating outer sheath is made of polytetrafluoroethylene (PTFE), and the protective rope is made of tough fiber. These components provide the insulating outer sheath with good insulation and high-temperature resistance, and the protective rope enhances the toughness of the insulating outer sheath.

These components provide the metal shielding mesh with good flexibility, and the metal wires enhance the plasticity of the electric heating cable, facilitating its installation.

[0012] According to the present invention, an easy-to-install electric heating tape is provided, wherein the adjustable heat-conducting layer is made of PTC material, and a conductor core wire is fixedly connected to the inner side wall of the adjustable heat-conducting layer. These components enable the adjustable heat-conducting layer to achieve good temperature control, and the conductor core wire connects it to the circuit.

[0013] Beneficial effects:

At the same time, the sliding block can slide on the insulating outer sheath, and the adhesive layer can be used to effectively fix the insulating outer sheath. When the adhesive layer fails, the connecting plate can be replaced, making the electric heating cable reusable. Attached Figure Description

The protective rope 3 is made of tough fiber, improving the toughness of the insulating outer sheath 1. A metal shielding mesh 4 is fixedly connected. The metal shielding mesh 4 is woven from tin-plated soft round copper wire, which improves the shielding effect of the electric heating tape against electromagnetic interference and has good toughness. Metal wires 5 are fixedly connected to the inner side wall of the metal shielding mesh 4, which improves the plasticity of the metal shielding mesh 4. An adjustable heat conduction layer 6 is fixedly connected to the inner side wall of the metal shielding mesh 4. The material of the adjustable heat conduction layer 6 is PTC material, which enables the electric heating tape to automatically limit the temperature during heating and automatically adjust the output power according to the temperature of the heated system without any additional equipment. A conductor core wire 7 is fixedly connected to the inner side wall of the adjustable heat conduction layer 6 for connecting the circuit.

[0024] A positioning block 8 is slidably connected to the side surface of the insulating outer sheath 1, which can slide along the insulating outer sheath 1, so that the punch 13 can punch the positioning hole 12 in a suitable position. A spring 14 is fixedly connected to the upper surface of the positioning block 8, which drives the punch 13 to pop out from the positioning hole 12. A pressing block 9 is fixedly connected to the end of the spring 14 away from the positioning block 8. Pressing the pressing block 9 can make the punch 13 punch the positioning hole 12 in the insulating outer sheath 1. A punch 13 is fixedly connected to the end of the pressing block 9 near the spring 14, so that the positioning hole 12 can be punched in the insulating outer sheath 1 when the pressing block 9 is pressed. A limiting block 10 is fixedly connected to the upper surface of the positioning block 8, which restricts the sliding of the pressing block 9, so that the punch 13 can punch the positioning hole 12 vertically. The side surface of the pressing block 9 is slidably connected to the limiting block 10.

[0025] The fixing component 11 includes a sliding block 15, which can slide along the insulating outer sheath 1 to fix the electric heating cable in a suitable position. A slot 16 is provided on the lower surface of the sliding block 15, into which a locking block 18 can be inserted to fix the connecting plate 17 together with the sliding block 15. The locking block 18 is slidably connected to the lower surface of the sliding block 15, and can be inserted into the slot 16 to fix the connecting plate 17. The connecting plate 17 can be removed and replaced when the adhesive layer 19 loses its function. The end of the locking block 18 away from the sliding block 15 is fixedly connected to the connecting plate 17. 7. An adhesive layer 19 is fixed on the surface and can be replaced along with the locking block 18. The end of the connecting plate 17 away from the locking block 18 is fixedly connected to the adhesive layer 19, which can fix the electric heating cable to the item to be adsorbed. The inner side of the sliding block 15 is slidably connected to the insulating outer sheath 1. The side surface of the locking block 18 is fixedly connected to the sliding block 15 inside the locking groove 16 in the working position. The side surface of the insulating outer sheath 1 is provided with a positioning hole 12. The end of the punching nail 13 away from the pressing block 9 passes through the upper surface of the positioning block 8 and extends into the interior of the insulating outer sheath 1.

[0026] Working principle: When the electric heat tracing cable needs to be installed, slide the positioning block 8 to the appropriate position and press the pressing block 9. The pressing block 9 drives the drilling nail 13 to drill the positioning hole 12 in the insulating outer sheath 1. Together with the tear-through hole 2, a section of the insulating outer sheath 1 can be removed. Then, the excess metal shielding mesh 4 and the adjusting heat conduction layer 6 are removed and the conductor core wire 7 is connected. The adjusting heat conduction layer 6 of the electric heat tracing cable has the function of regulating temperature, and the metal shielding mesh 4 effectively improves the shielding effect of the electric heat tracing cable against electromagnetic interference. Then, slide the sliding block 15 to the appropriate position and fix the electric heat tracing cable with the adhesive layer 19. When the electric heat tracing cable needs to be re-fixed, the locking block 18 drives the connecting plate 17 to slide out of the slot 16, and a new connecting plate 17 is replaced and re-inserted into the slot 16 to fix the electric heat tracing cable.
