Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cable radiation auxiliary equipment, and in particular relates to a grounding fixture for irradiated cables. Background Technology
[0002] Cable radiation technology is a technique that modifies the insulation and sheath materials of cables by cross-linking them with high-energy radiation (electron beams or gamma rays). The cross-linked materials can operate at higher temperatures, are more stable under physical and chemical conditions, have improved mechanical strength, and extended service life. The entire radiation process involves no chemical cross-linking additives, reducing environmental pollution.
[0003] During the cable irradiation process, a suitable cross-linked polymer material must first be selected. After the cable core is made through extrusion, the cable is sent into the irradiation chamber for irradiation treatment through a conveying system. After irradiation, the cable is cooled through a cooling system to prevent the material from overheating.
[0004] During cable irradiation, the cable insulation or sheath material may generate static electricity under high-energy radiation, attracting dust and impurities, affecting irradiation uniformity. Static discharge can also cause sparks, posing an explosion risk. Irradiation equipment can also generate electromagnetic interference or overvoltage during the irradiation process. Grounding can quickly conduct static electricity or high voltage to the earth, preventing static buildup and protecting equipment and personnel. In cable grounding, materials with good conductivity, such as conductors, shielding layers, and armor, are typically used as grounding conductors. It is crucial to ensure a secure grounding connection, preventing loosening or corrosion.
[0005] To connect the cable to be irradiated to the traction line, operators typically use wire strippers to remove the insulation and shielding layers at the cable ends and manually crimp the conductors to the front conductor. This serves both as a traction mechanism and as a way to ensure the grounding of the cable to be irradiated. However, this manual connection method is inefficient, complex, and prone to errors, requiring operators to have a high level of skill. In mass production, it is difficult to meet the requirements of high efficiency and high consistency. Utility Model Content
[0006] To address the aforementioned problems in the prior art, this utility model aims to provide a grounding fixture for irradiated cables, which solves the problems of low grounding efficiency, complex operation, and easy errors caused by the reliance on manual wiring for grounding existing irradiated cables.
[0007] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:
[0008] A grounding fixture for irradiated cables is provided, which includes a cable fixing device and a traction wire fixing device, and a conductive connector is provided between the cable fixing device and the traction wire fixing device.
[0009] Both the cable fixing device and the traction wire fixing device are equipped with at least one conductive puncture needle. The conductive puncture needle in the cable fixing device passes through the insulation layer and shielding layer of the cable to be irradiated and is electrically connected to the conductor inside it. The conductive puncture needle in the traction wire fixing device passes through the traction wire and is electrically connected to the conductor inside it.
[0010] The conductive puncture needles in the cable fixing device and the traction line fixing device are electrically connected to each other.
[0011] The working principle of the above-mentioned irradiated cable grounding fixture is as follows: First, the cable fixing device is fixed to the end of the cable to be irradiated, and the conductive puncture needle is inserted into the cable to contact its internal conductor. Next, the traction wire fixing device is fixed to the end of the traction wire, and the conductive puncture needle is inserted into the traction wire to contact its internal conductor. Simultaneously, due to the conductive connector, a traction connection is achieved between the cable to be irradiated and the traction wire. Because of the conductive puncture needles in the cable fixing device and the traction wire fixing device, the static electricity accumulated on the cable to be irradiated can be conducted to the traction wire, grounding the conductor in the traction wire, ultimately achieving grounding of the cable to be irradiated. The conductive path of static electricity on the cable to be irradiated is first through the conductive puncture needle on the cable fixing device to the conductive connector, and then through the conductive puncture needle in the traction wire fixing device into the conductor in the traction wire, thus achieving grounding of the cable to be irradiated.
[0012] Furthermore, as a specific arrangement of the cable fixing device and the traction line fixing device, both the cable fixing device and the traction line fixing device include a conductive fixing clamp. Each conductive fixing clamp includes an upper conductive clamp body and a lower conductive clamp body. A hinge is provided between the upper conductive clamp body and the lower conductive clamp body. One side of the upper conductive clamp body and the lower conductive clamp body is hinged together by the hinge. A conductive puncture needle is provided on the clamping surface of the upper conductive frame.
[0013] When fixing the cable fixing device and the traction line fixing device to the cable to be irradiated or the traction line, the upper conductive clamp and the lower conductive clamp can be opened first, then the cable to be irradiated or the traction line can be placed into the conductive fixing clamp, and finally the upper conductive clamp can be pressed down to insert the conductive piercing needle into the cable to be irradiated or the traction line and make it in contact with the conductor, so as to realize the conductivity and fixation of the conductive fixing clamp.
[0014] Furthermore, the clamping surfaces of both the upper and lower conductive clamps are arc-shaped curved surfaces, and the curvature of these surfaces matches the outer diameter of the cable to be irradiated and the traction wire. This design ensures a closer fit between the clamping surfaces of the upper and lower conductive clamps and the outer circumference of the cable to be irradiated and the traction wire, resulting in a more stable clamping action and preventing detachment.
[0015] Furthermore, multiple conductive puncture needles are evenly spaced along the axial direction on the clamping surface of the upper conductive clamp. This arrangement makes the connection between the conductive clamp and the cable to be irradiated and the traction wire more stable. At the same time, by increasing the number of conductive puncture needles, it is easier for the conductive puncture needles to contact the conductors in the cable to be irradiated and the traction wire.
[0016] Furthermore, as a specific configuration of the conductive puncture needles, each conductive puncture needle is a conical structure with its tip pointing downwards, and the tail end of the conductive puncture needle is fixedly connected to the clamping surface of the upper conductive clamp. By defining the conductive puncture needle as a conical structure, not only can it be more easily inserted into the irradiated cable and traction wire, but it also prevents the conductive puncture needle from deforming, thus increasing its service life.
[0017] Furthermore, the conductive connector is a metal chain, with both ends of the metal chain being fixedly connected to conductive clamps or hinges in the cable fixing device and the traction line fixing device, respectively. The metal chain provides a flexible connection between the cable fixing device and the traction line fixing device. The metal chain also has the advantage of high tensile strength, effectively ensuring that the fixture is not broken during traction, making it suitable for the traction process of the cable to be irradiated.
[0018] Furthermore, the upper and lower conductive clamps are vertically symmetrically arranged with the hinge central axis as the center. The clamping surfaces of the upper and lower conductive clamps form circular clamping grooves, and the length of each conductive puncture needle is 1 / 2 to 2 / 3 of the diameter of the circular clamping groove. By limiting the length of the conductive puncture needles, the insertion depth of the conductive puncture needles is controlled, ensuring a stable connection between the conductive puncture needles and the cable to be irradiated or the traction wire.
[0019] Furthermore, each conductive puncture needle and each conductive fixation clip is made of an alloy conductive material. The alloy conductive material combines the high conductivity of metals with the excellent mechanical properties and cost-effectiveness of alloys, ensuring the structural strength and conductivity of the conductive puncture needle and conductive fixation clip.
[0020] Compared with existing irradiated cable grounding systems that rely on manual wiring, the advantages of this invention are as follows:
[0021] This utility model discloses a grounding fixture for irradiated cables, which can replace manual wiring and significantly improve the wiring speed between the cable to be irradiated and the traction line, enabling batch wiring during the cable irradiation process. The grounding fixture ensures consistent wiring quality between the cable to be irradiated and the traction line through precise positioning and the crimping of conductive puncture needles, reducing human error. The conductive fixing clamp can adapt to different types and specifications of cables, has a wide range of applications, and can be used in a wide range of scenarios. Attached Figure Description

[0024] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All inventions utilizing the concept of this utility model are protected.
[0025] like Figure 1 As shown, this utility model provides a grounding fixture for irradiated cables, which includes a cable fixing device 1 and a traction wire fixing device 2. A conductive connector 3 is provided between the cable fixing device 1 and the traction wire fixing device 2. Both the cable fixing device 1 and the traction wire fixing device 2 are provided with at least one conductive piercing needle 4. The conductive piercing needle 4 in the cable fixing device 1 passes through the insulation layer and shielding layer of the cable to be irradiated and is electrically connected to the conductor inside it. The conductive piercing needle 4 in the traction wire fixing device 2 passes through the traction wire and is electrically connected to the conductor inside it. The conductive piercing needles 4 in the cable fixing device 1 and the traction wire fixing device 2 are electrically connected to each other.
[0026] When using the grounding fixture for irradiated cables, firstly, fix the cable fixing device 1 to the end of the cable to be irradiated and insert the conductive puncture needle 4 into the cable to be irradiated and make contact with its internal conductor. Next, fix the traction wire fixing device 2 to the end of the traction wire and insert the conductive puncture needle 4 into the traction wire and make contact with its internal conductor. At the same time, due to the setting of the conductive connector 3, the traction connection between the cable to be irradiated and the traction wire is realized. Due to the setting of the conductive puncture needle 4 in the cable fixing device 1 and the traction wire fixing device 2, the static electricity accumulated on the cable to be irradiated can be conducted to the traction wire, and the conductor in the traction wire is grounded, thus realizing the grounding of the cable to be irradiated. The conductive path of the static electricity on the cable to be irradiated is that it first flows through the conductive puncture needle 4 on the cable fixing device 1 to the conductive connector 3, and then through the conductive puncture needle 4 in the traction wire fixing device 2 into the traction wire and into the conductor, thus realizing the grounding of the cable to be irradiated.
[0027] As a specific arrangement of the cable fixing device 1 and the traction line fixing device 2, both the cable fixing device 1 and the traction line fixing device 2 include a conductive fixing clip 5. Each conductive fixing clip includes an upper conductive clip body 501 and a lower conductive clip body 502. A hinge 6 is provided between the upper conductive clip body 501 and the lower conductive clip body 502. One side of the upper conductive clip body 501 and the lower conductive clip body 502 is hinged by the hinge 6. A conductive piercing needle 4 is provided on the clamping surface of the upper conductive clip body. When the cable fixing device 1 and the traction line fixing device 2 are fixed on the cable to be irradiated or the traction line, the upper conductive clip body 501 and the lower conductive clip body 502 can be opened first. Then, the cable to be irradiated or the traction line can be placed into the conductive fixing clip 5. Finally, the upper conductive clip body 501 is pressed down to insert the conductive piercing needle 4 into the cable to be irradiated or the traction line and make contact with the conductor, so as to realize the conductivity and fixation of the conductive fixing clip 5.
[0028] Multiple conductive puncture needles 4 are evenly spaced along the axial direction on the clamping surface of the upper conductive clamp 501. This arrangement makes the connection between the conductive fixing clamp 5 and the cable to be irradiated and the traction wire more stable. Simultaneously, by increasing the number of conductive puncture needles 4, it is easier for the conductive puncture needles 4 to contact the conductors in the cable to be irradiated and the traction wire. Preferably, each conductive puncture needle 4 has a conical structure with its tip pointing downwards, and the tail end of the conductive puncture needle 4 is fixedly connected to the clamping surface of the upper conductive clamp 501. Limiting the conductive puncture needles 4 to a conical structure not only makes it easier for the conductive puncture needles 4 to be inserted into the cable to be irradiated and the traction wire, but also prevents the conductive puncture needles 4 from deforming, increasing their service life.
[0029] Preferably, but not limited to, the clamping surfaces of both the upper conductive clamp 501 and the lower conductive clamp 502 are arc-shaped curved surfaces, and the curvature of the clamping surfaces of the upper conductive clamp 501 and the lower conductive clamp 502 is adapted to the outer diameter of the cable to be irradiated and the traction wire. This configuration allows the clamping surfaces of the upper conductive clamp 501 and the lower conductive clamp 502 to fit more closely to the circumferential outer wall of the cable to be irradiated and the traction wire, making the conductive fixing clamp 5 more stable and preventing it from falling off.
[0030] As one specific configuration, the conductive connector 3 is a metal chain, with both ends of the metal chain fixedly connected to the conductive fixing clips 5 or hinges 6 in the cable fixing device 1 and the traction line fixing device 2, respectively. The metal chain provides a flexible connection between the cable fixing device 1 and the traction line fixing device 2. The metal chain has the advantage of high tensile strength, effectively ensuring that the fixture is not broken during traction, making it suitable for the traction process of the cable to be irradiated.
[0031] The upper conductive clamp 501 and the lower conductive clamp 502 are vertically symmetrically arranged with the horizontal plane containing the central axis of the hinge 6 as the center. The clamping surfaces of the upper conductive clamp 501 and the lower conductive clamp 502 form a circular clamping groove. The length of each conductive puncture needle 4 is 1 / 2 to 2 / 3 of the diameter of the circular clamping groove. By limiting the radius of the conductive puncture needle 4, the insertion depth of the conductive puncture needle 4 is controlled, ensuring a stable connection between the conductive puncture needle 4 and the cable to be irradiated or the traction wire.
[0032] Each conductive puncture needle 4 and each conductive clamp 5 is made of an alloy conductive material. The alloy conductive material combines the high conductivity of metals with the excellent mechanical properties and cost-effectiveness of alloys, ensuring the structural strength and conductivity of the conductive puncture needle 4 and the conductive clamp 5.
[0033] In summary, the irradiated cable grounding fixture of this invention can replace manual wiring, significantly improving the wiring speed between the cable to be irradiated and the traction line, and enabling batch wiring during the cable irradiation process. The irradiated cable grounding fixture ensures consistent wiring quality between the cable to be irradiated and the traction line through precise positioning and the crimping of the conductive piercing needle 4, reducing human error. The conductive fixing clamp 5 is adaptable to different cable models and specifications, has a wide range of applications, and is suitable for various application scenarios.
