Description

Technical Field

[0001] This utility model belongs to the technical field of high conductivity beryllium copper alloy rods, and particularly relates to an assembly structure for high conductivity beryllium copper alloy rods. Background Technology

[0002] High conductivity beryllium copper alloy rods are copper-based alloy rods containing 0.2% to 0.6% beryllium and added elements such as cobalt and nickel. After solution treatment and aging, the conductivity reaches 45% to 80% IACS. They have mechanical properties with tensile strength ≥800MPa and a wide temperature resistance of -200℃ to 300℃. Because they are non-magnetic, fatigue-resistant, and do not produce sparks upon impact, they are often used in semiconductor electrodes, high-frequency communication feeders, and conductive connectors for new energy batteries. They can meet the low resistance conduction requirements of precision circuits and can be cold-drawn or machined into various rod-shaped components. However, their production requires control of beryllium vapor toxicity, and the cost is 3 to 8 times higher than that of ordinary copper rods. They are suitable for industrial applications that require both high conductivity and mechanical properties.

[0003] When a highly conductive beryllium copper alloy rod is used as a ground electrode, the wire and the beryllium-containing beryllium copper alloy rod are exposed to the outside, resulting in a relatively fast oxidation rate. Applying paint is not conducive to inspection and maintenance, thus causing the problem of rapid oxidation at the connection point when the highly conductive beryllium copper alloy rod is used as a ground electrode.

[0004] To address this issue, we propose a highly conductive beryllium copper alloy rod assembly structure. Utility Model Content

[0005] The purpose of this invention is to solve the problem of rapid oxidation at the connection point when a highly conductive beryllium copper alloy rod is used as a ground electrode, and to propose an assembly structure for the highly conductive beryllium copper alloy rod.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An assembly structure for a highly conductive beryllium copper alloy rod includes a high-conductivity beryllium copper alloy rod body. A sealing shell, a sealing cap, and a steel hoop are fitted onto the high-conductivity beryllium copper alloy rod body. The steel hoop is clamped onto the high-conductivity beryllium copper alloy rod body. The sealing cap is in sealing contact with the high-conductivity beryllium copper alloy rod body. The sealing shell is in sealing contact with the high-conductivity beryllium copper alloy rod body. The sealing cap and the sealing shell are fitted together. The lower part of the sealing shell is fastened to the sealing cap. A screw is installed on the side of the steel hoop. A terminal is clamped between the steel hoop and the screw. A threaded sleeve is threaded onto the upper part of the sealing shell. A sealing ring is provided between the sealing shell and the threaded sleeve. First, place the sealing cap on the high-conductivity beryllium copper alloy rod body, then place the steel hoop on the high-conductivity beryllium copper alloy rod body. Place the terminal block on the screw and tighten the screw to fix it. Use the screw to tighten the steel hoop, so that the steel hoop is fixed on the high-conductivity beryllium copper alloy rod body. Then, pass the target wire through the threaded sleeve, sealing ring, and sealing shell to connect to the terminal block. Place the sealing shell on the high-conductivity beryllium copper alloy rod body, so that the sealing cap is fastened to the lower part of the sealing shell. Use the sealing cap to seal the lower part of the sealing shell, sealing the connection point between the target wire and the terminal block inside, reducing the oxidation rate at the connection.

[0008] Preferably, the sealing shell includes a housing, on which a threaded nozzle and a first sealing ring are fixedly connected. The first sealing ring is fitted onto the high-conductivity beryllium copper alloy rod body. The threaded nozzle is used for threaded installation of the threaded sleeve, and the first sealing ring is used to seal the gap between the housing and the high-conductivity beryllium copper alloy rod body.

[0009] Preferably, the sealing cover includes a cover body, and a second sealing ring is fixedly connected to the upper part of the cover body. The second sealing ring is embedded inside the housing. The lower part of the housing is sealed by the second sealing ring embedded inside the housing.

[0010] Preferably, the sealing cover further includes a spring clip, the lower end of which is fixedly connected to the cover body, and the spring clip engages with the lower part of the housing. By using the spring clip to engage with the lower part of the housing, the sealing cover is held at the bottom of the sealing shell, improving the stability of the mating state between the sealing shell and the sealing cover.

[0011] Preferably, the sealing ring includes a shrink sleeve, and a rubber ring is fixedly connected inside the shrink sleeve. The lower end of the rubber ring is in movable contact with the threaded nozzle. After the threaded sleeve is tightened, the threaded sleeve presses the shrink sleeve inward, causing the shrink sleeve to act inward on the rubber ring, so that the rubber ring seals the outer sheath of the target wire, facilitating the sealing of the gap between the target wire and the sealing shell.

[0012] Preferably, the threaded sleeve includes a sleeve body, the lower end of which is fixedly connected to a threaded ring. The sleeve body is movably fitted over the shrink frame, and the threaded ring is threaded onto the threaded nozzle. Tightening the threaded sleeve causes the threaded ring to spiral downwards along the threaded nozzle. The threaded ring acts downwards on the sleeve body, causing the sleeve body to tighten inwards towards the shrink frame, facilitating the tightening and sealing of the sealing ring.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. First, place the sealing cap on the high-conductivity beryllium copper alloy rod body, then place the steel hoop on the high-conductivity beryllium copper alloy rod body. Place the terminal block on the screw and tighten the screw to fix it. Use the screw to tighten the steel hoop, so that the steel hoop is fixed on the high-conductivity beryllium copper alloy rod body. Then, pass the target wire through the threaded sleeve, sealing ring, and sealing shell to connect to the terminal block. Place the sealing shell on the high-conductivity beryllium copper alloy rod body, so that the sealing cap is fastened to the lower part of the sealing shell. Use the sealing cap to seal the lower part of the sealing shell, sealing the connection point between the target wire and the terminal block inside, reducing the oxidation rate at the connection.

[0015] 2. The spring clip is used to fasten the cover to the bottom of the housing, keeping the sealing cover at the bottom of the housing and improving the stability of the mating state between the sealing cover and the sealing cover.

[0016] 3. After tightening the threaded sleeve, use the threaded sleeve to press the shrink bracket inward, so that the shrink bracket acts inward on the rubber ring, so that the rubber ring seals on the outer sheath of the target wire, which facilitates sealing the gap between the target wire and the sealing shell.

[0017] 4. Tighten the threaded sleeve so that the threaded ring spirals downward along the threaded nozzle. The threaded ring acts downward on the sleeve body, causing the sleeve body to tighten inward and shrink the sleeve, making it easier to tighten and seal the sealing ring.
