Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire splicing equipment, and more specifically, to a splicing tube for quick crimping. Background Technology
[0002] In the field of power transmission, conductor splicing is a crucial task, as its quality directly affects the safe and stable operation of the power system. Traditional carbon fiber composite conductors and steel-cored aluminum stranded wires typically use splicing conduits consisting of two parts: a steel tube for crimping the steel core and an outer aluminum tube. During conductor splicing, specific procedures must be strictly followed. First, the steel core of the conductor must be accurately placed inside the steel tube for crimping. This step requires highly skilled and experienced personnel to ensure a secure connection between the steel core and the tube. Next, the aluminum wire is crimped, placed inside the outer aluminum tube. Specific construction techniques can be found in relevant standard documents.
[0003] Traditional splicing pipe installation is complex and requires a high level of expertise from the installers. The process involves multiple steps and precise operations; any deviation in any step can affect the splice quality. In actual installation, it's difficult to ensure perfect symmetry between the two ends of the conductor when inserting into the splice pipe. Due to a lack of effective positioning methods, installers often rely on experience and visual judgment to determine the insertion position. If the insertion positions of the two ends are asymmetrical, the crimped conductors will experience uneven stress. During power line operation, this uneven stress can lead to localized stress concentration in the conductors, accelerating aging and damage, and significantly increasing the risk of line failure. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fast crimping splice tube.
[0005] The technical solution adopted in this utility model is:
[0006] A quick-press splice tube includes: a splice tube body, with a gasket crimped and fixed in the middle inside the splice tube body; and two liner structures for fitting onto the outside of the wire are disposed inside the splice tube body, with the two liner structures arranged opposite to each other on both sides of the gasket.
[0007] Furthermore, the grooves inside the liner structure are bonded with a diamond abrasive anti-slip layer formed of diamond abrasive.
[0008] Furthermore, the corundum is bonded to the groove of the liner structure using high-temperature resistant epoxy resin.
[0009] Furthermore, the liner structure includes: two liner bodies that are arranged in a relatively mating manner, each liner body having a snap-fit structure and a slot structure at both ends; when the two liner bodies are mated and fastened to the outside of the conductor, the snap-fit structure and slot structure of the two liner bodies engage with each other.
[0010] Furthermore, the outer sides of the snap-fit structure and the slot structure that mate the two liner bodies form a draft angle.
[0011] Furthermore, the liner body is a semi-circular tube.
[0012] Furthermore, the liner body is made of aluminum tubing.
[0013] Furthermore, the liner structure also includes: an O-ring; a semi-annular groove is provided on the outer ring surface of the liner body, and the O-ring is fitted into the annular groove formed by the two semi-annular grooves when the two liner bodies are joined.
[0014] Furthermore, the connecting pipe body includes: a straight pipe body and a tapered pipe body integrally formed at both ends of the straight pipe body, the straight pipe body and the tapered pipe body having the same inner diameter; the outer diameter of the tapered pipe body gradually increases from the end away from the straight pipe body to the end closer to the straight pipe body.
[0015] Furthermore, the end of the tapered tube away from the straight tube has a rounded corner.
[0016] As can be seen from the above solution, the beneficial effects of this utility model are as follows:
[0017] In this invention, a quick-crimping splice tube is constructed by pressing a fixed gasket into the middle of the splice tube body. The liner structure uses the gasket as a reference to accurately determine the position of the wire inserted into the splice tube body, improving the accuracy and efficiency of positioning. This avoids crimping offset caused by inaccurate insertion position, ensuring the stability and consistency of the crimping process. It also ensures that the stress on each part is evenly distributed after crimping, reducing the risk of damage to the wire due to uneven stress during long-term operation.

[0029] To ensure a clear and complete description of the technical solutions in the embodiments of this utility model below, in conjunction with the accompanying drawings, it is evident that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0030] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.
[0031] Example 1
[0032] Please see Figures 1-8 This utility model provides a quick-press splice tube, including: a splice tube body 1, with a gasket 2 pressed and fixed in the middle inside the splice tube body 1; two liner structures 3 are provided inside the splice tube body 1 for fitting on the outside of the wire, and the two liner structures 3 are arranged opposite to each other on both sides of the gasket 2.
[0033] The working principle and technical effects of the above technical solution are as follows:
[0034] In this invention, a quick-crimping splice tube has a gasket 2 fixedly crimped in the middle inside the splice tube body 1. During the crimping of two conductors, two liner structures 3 are respectively fitted onto the outside of the conductors. The liner structures 3 containing the conductors are then inserted into the splice tube body 1. Because the gasket 2 is fixed in position, the liner structures 3, using the gasket as a reference, can accurately determine the position of the conductor insertion into the splice tube body 1. Construction personnel do not need to rely on experience or visual judgment to determine the conductor insertion position, thus effectively improving the accuracy and efficiency of positioning. This allows the two liner structures 3 and the fitted conductors to be accurately inserted into the splice tube body 1 according to the preset position. During the crimping process, the conductor position is effectively constrained, thus avoiding crimping offset caused by inaccurate insertion position, ensuring the stability and consistency of the crimping process. Because the conductor insertion position is accurate, the stress on each part can be evenly distributed after crimping, avoiding localized stress concentration. This effectively reduces damage to the conductors caused by uneven stress during long-term operation, improves the mechanical and electrical performance of the conductor splice, and ensures the stable operation of the power line.
[0035] The inner groove of the liner structure 3 is bonded with a corundum anti-slip layer formed of corundum. The corundum is bonded to the groove of the liner structure 3 using high-temperature resistant epoxy resin. This corundum anti-slip layer effectively increases the friction between the liner structure 3 and the conductor under pressure. This increased friction makes the connection between the conductor and the liner structure 3 tighter and more stable, significantly improving the gripping force of the splice. In practical use, the conductor is less likely to detach from the splice, ensuring the reliability of conductor connections in power transmission lines and reducing faults and safety hazards caused by loose conductors. Especially in power lines operating under complex conditions such as vibration and tension, the higher gripping force helps maintain conductor stability within the splice. For example, in windy outdoor environments or industrial sites with mechanical vibration, the enhanced friction can resist the influence of external factors on the conductor connection, ensuring continuous and stable power transmission. Emery, with its high hardness and excellent wear resistance, acts as an anti-slip layer, resisting frictional loss between the conductor and the liner during long-term use and ensuring the long-term stability of its performance. The emery is bonded to the cable tray within the liner structure using high-temperature resistant epoxy resin. This high-temperature epoxy resin maintains excellent adhesion at high temperatures, ensuring the emery anti-slip layer is firmly attached to the inner wall of the liner. During power transmission, conductors may heat up due to current flow, especially under overload or short-circuit conditions, where the temperature can rise significantly. The high-temperature resistance of the emery anti-slip layer prevents it from detaching or failing under high-temperature conditions, ensuring the connector operates normally in various temperature environments.
[0036] Example 2
[0037] Please see Figures 1-8 This utility model provides a quick-pressing splice tube, in which the liner structure 3 includes: two liner bodies 310 arranged opposite to each other, each liner body 310 having a snap-fit structure 320 and a slot structure 330 at both ends; when the two liner bodies 310 are butted and fastened to the outside of the wire, the snap-fit structure 320 and the slot structure 330 of the two liner bodies 310 engage with each other. The snap-fit structure 320 and the slot structure 330 of the two liner bodies 310 form a draft angle on their outer sides. The liner body 310 is a semi-circular tube. The liner body 310 is an aluminum tube.
[0038] The working principle and technical effects of the above technical solution are as follows:
[0039] When fixing the conductor, the two liner bodies 310 are joined together from both sides of the conductor, so that the snap-fit structure 320 of one liner body 310 and the slot structure 330 of the other liner body 310 engage with each other. Due to the snap-fit and slot design, the two liner bodies 310 can be firmly connected together to form a complete liner structure that fits over the conductor. Through the engagement of the snap-fit structure 320 and the slot structure 330, the two liner bodies 310 can be quickly and easily joined and fastened to the outside of the conductor without the need for additional tools or complicated installation steps, which greatly improves installation efficiency and reduces labor costs. A draft angle is formed on the outside of the snap-fit structure 320 and the slot structure 330 of the two liner bodies 310, that is, a concave-convex clearance is formed on the outside of the snap-fit structure 320 and the slot structure 330 of the two liner bodies 310, which makes it easier for the product to be separated from the mold during the mold manufacturing process.
[0040] The liner body 310 is designed as a semi-circular tube. When two semi-circular tubes are joined together, they can form a complete circular tube, which can effectively wrap the wire and provide all-round protection. The liner body 310 is made of aluminum tube. Aluminum has good electrical conductivity, thermal conductivity and corrosion resistance. Good electrical conductivity can shield electromagnetic interference to a certain extent and protect the stable transmission of signals inside the wire. Thermal conductivity helps to dissipate the heat generated by the wire and prevent the wire from being damaged due to overheating. Corrosion resistance ensures that the liner can be used for a long time under different environmental conditions, extending the service life of the liner and the wire.
[0041] Furthermore, the snap-fit mechanism of the buckle structure 320 and the slot structure 330 ensures that the two liner bodies 310 are firmly connected, guaranteeing that the liner structure 3 will not easily separate during use, thus providing stable protection and support for the conductor.
[0042] The liner structure 3 also includes an O-ring 4. A semi-annular groove is provided on the outer ring surface of the liner body 310. The O-ring 4 is fitted into the annular groove formed by the two semi-annular grooves when the two liner bodies 310 are joined. The O-ring 4 abuts against the inner wall of the connecting tube body 1. The O-ring provides a certain radial pressure within the annular groove, making the two liner bodies 310 more tightly joined together when joined. The additional pressure enhances the connection stability between the two liner bodies 310, reducing the possibility of loosening or separation of the two liner bodies 310 due to external forces such as vibration and impact, ensuring the integrity and reliability of the conductor wrapping structure. Furthermore, when the liner structure 3 is subjected to external vibration or impact, the elasticity of the O-ring 4 can buffer and dampen the shock, absorbing some energy, reducing the direct impact of vibration and impact on the conductor, lowering the risk of conductor failure due to mechanical damage, and extending the service life of the conductor.
[0043] The connector body 1 includes a straight tube 110 and tapered tubes 120 integrally formed at both ends of the straight tube 110. The straight tube 110 and tapered tubes 120 have the same inner diameter. The outer diameter of the tapered tube 120 gradually increases from the end away from the straight tube 110 to the end closer to the straight tube 110. The end of the tapered tube 120 away from the straight tube 110 has a rounded corner. The rounded corner at the end of the tapered tube 120 away from the straight tube 110 avoids sharp edges from scratching or abrading the wire. During wire insertion, the rounded corner allows the wire to smoothly transition into the tapered tube 120, protecting the insulation layer and conductor of the wire and ensuring that the integrity and performance of the wire are not compromised.
