Description

Technical Field

[0001] This invention relates to the technical field of electrical connection clamp structures, specifically to electrical connection clamp assemblies for electrical connection wires. The invention also provides a method for manufacturing the electrical connection clamp assembly. Background Technology

[0002] The overhead contact system is a crucial component of electrified railways. The pantograph on an electric locomotive directly contacts the contact wire to obtain current, providing the power needed for train operation. The electrical connecting wire is a key component of the catenary-type overhead contact system. Its use enables series and parallel connections between contact suspensions, thus ensuring current flow between different devices in the contact system, balancing potentials, and guaranteeing power supply reliability. Therefore, the reliability of the electrical connecting wire is critical to the safe and stable power supply of the electrified railway's overhead contact system.

[0003] The current standard for overhead contact lines, TB / T 2075.11-2024, mainly consists of two parts: the electrical connection cable body and the positioning clamps. Only TJR1 type soft copper stranded wire is allowed to be used for the electrical connection cable. There are three types of clamps: bolt type, crimp type, and crimp and bolt type. Because crimp type clamps have the characteristics of low contact resistance, strong current carrying stability, compact structure, and light weight, they can reduce the extra load on the overhead contact line and increase the vibration resistance of the overhead contact line. Therefore, crimp type clamps are mostly used in current railway construction. However, the crimp type clamps currently used in railway overhead contact lines often cause damage to the wires during installation, which reduces the fatigue resistance of the electrical connection cable device, thereby shortening its service life and increasing railway maintenance costs.

[0004] Currently, there is no clear and efficient solution in China to improve the damage problem of crimp-type clamps. Therefore, it is of great significance to study the damage-free electrical connection clamps and high-durability electrical connection devices. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an electrical connection clamp assembly for electrical connection wires, which reduces the damage to the electrical connection wires during the crimping process, thereby increasing the overall service life of the electrical connection mechanism.

[0006] An electrical connection clamp assembly for electrical connection wires, characterized in that it comprises: A catenary cable connector clamp includes a C-type clamp, a C-type clamp anti-pressure pad, and a pressure block. The C-type clamp anti-pressure pad is positioned inside the inner cavity of the C-type clamp. The notches of the C-type clamp and the C-type clamp anti-pressure pad are arranged in the same direction. The inner cavity of the C-type clamp anti-pressure pad forms an installation cavity for the catenary cable and the electrical connector. The pressure block separates and arranges the catenary cable and the electrical connector. The contact wire connection clamp includes an E-type clamp, an E-type clamp anti-pressure pad, and a pair of threaded clips. The E-type clamp includes a contact wire clamping cavity with an upper closed circular cavity and a lower downward open contact wire clamping cavity. The E-type clamp anti-pressure pad is positioned inside the upper closed circular cavity. The E-type clamp anti-pressure pad has a circular ring structure. The inner cavity of the E-type clamp anti-pressure pad is used to place the electrical connection wire. The lower part of the E-type clamp is provided with a pair of clamping claws that expand outward from top to bottom. The inner wall of each clamping claw is concave to form an arc-shaped positioning groove. Part of the arc surface of the threaded clip is positioned and embedded in the arc-shaped positioning groove, and part of the arc surface of the threaded clip is positioned and embedded in the corresponding side suspension groove of the contact wire. Both the C-type wire clamp anti-pressure pad and the E-type wire clamp anti-pressure pad are annealed, and their hardness after annealing is 35-45HV.

[0007] Its further features are: The inner cavity of the C-type clamp is provided with a first concave positioning groove at the center position of the width direction away from the notch, and the outer surface of the anti-pressure pad of the C-type clamp is provided with a first protruding positioning at the center position of the width direction away from the notch. In the assembled state, the first protruding positioning is embedded in the first concave positioning groove to ensure reliable alignment and assembly of the C-type clamp and the anti-pressure pad of the C-type clamp, so that the overall structure is stable when clamping the load-bearing cable and the electrical connection wire. The pressure block has concave contoured arc grooves on both sides facing the end faces of the load-bearing cable and the electrical connection wire, which allows the load-bearing cable and the electrical connection wire to be reliably embedded in the corresponding concave contoured arc grooves. The pressure block is provided with a bottom horizontal partition at the position facing the notch. When the pressure block is in the clamping position, the bottom horizontal partition is located directly above the notch position to ensure the stable and reliable position of the load-bearing cable and the electrical connection wire. At least one circumferential groove is provided on the inner wall of the upper closed circular cavity of the E-type clamp, and the outer circumference of the anti-pressure pad of the E-type clamp is provided with the same number and position of the second protrusion positioning as the second concave positioning groove. In the assembled state, the second protrusion positioning is correspondingly embedded in the second concave positioning groove to ensure reliable and stable clamping of the electrical connection wire. The C-type wire clamp, C-type wire clamp anti-pressure pad, pressure block, E-type wire clamp, and E-type wire clamp anti-pressure pad are all made of T2 copper, and the threaded clip is made of copper-nickel-silicon. The hardness of the C-type clamp, pressure block, and E-type clamp is 75-80 HV.

[0008] The method for manufacturing electrical connection clamp assemblies for electrical connection wires is characterized in that: C-type clamps, C-type clamp anti-pressure pads, pressure blocks, E-type clamps, and E-type clamp anti-pressure pads are all first smelted into oxygen-free copper rods by electrolytic copper in an upward continuous casting furnace, then directly extruded into shape by a continuous extrusion press, and then laser-cut to the required dimensions; threaded clips are obtained by machining. The C-type wire clamp anti-pressure pad and E-type wire clamp anti-pressure pad are annealed, and their hardness is 35-45HV after annealing. The C-type wire clamp, pressure block and E-type wire clamp do not require annealing and their hardness is 75-80HV.

[0009] A further feature is that the specific operating steps of the C-type wire clamp, C-type wire clamp anti-pressure pad, pressure block, E-type wire clamp, and E-type wire clamp anti-pressure pad are as follows: S1 upward continuous casting smelting: Electrolytic copper plate and trace alloys are added to an industrial frequency furnace to melt copper. The surface is covered with charcoal to isolate and absorb oxygen. It is cooled by cooling water to produce an upward continuous casting copper rod with a diameter of φ20mm. S2 Extrusion Processing: Using a horizontal continuous extrusion press, the upward continuous casting copper rod obtained in step S1 is extruded to obtain C-type wire clamps, C-type wire clamp anti-pressure pads, pressure blocks, E-type wire clamps, and E-type wire clamp anti-pressure pads of corresponding shapes. S3 Laser Cutting: Using laser cutting, the wire clamp rod blank obtained in step S2 is cut to obtain C-type wire clamp, C-type wire clamp anti-pressure pad, pressure block, E-type wire clamp, and E-type wire clamp anti-pressure pad respectively. S4 Annealing treatment: The C-type wire clamp anti-pressure pad, E-type wire clamp anti-pressure pad, and pad block are annealed, and their hardness after annealing is 35-45HV. S5 Surface Polishing and Deburring Treatment: The cut C-type wire clamps, C-type wire clamp anti-pressure pads, pressure blocks, E-type wire clamps, and E-type wire clamp anti-pressure pads are surface treated using a shot blasting machine.

[0010] When using the electrical connector clamp assembly of the present invention, both the C-type clamp anti-pressure pad and the E-type clamp anti-pressure pad are in an annealed state, with low hardness. They will deform preferentially during the crimping process, thereby reducing the pressure damage to the electrical connector. At the same time, the C-type clamp anti-pressure pad and the E-type clamp anti-pressure pad are positioned in the corresponding cavity, and the strength of the C-type clamp and the E-type clamp body remains unchanged, ensuring that the clamp meets the sliding load requirements. Therefore, when the electrical connector is connected to the catenary and contact wire located at the upper and lower positions through the electrical connector clamp assembly, it has better fatigue durability than conventional electrical connectors, thus having a longer service life.
