Embodiment 1

[0035] First, a SiC coating with a thickness of 0.6 μm was formed on the surface of the carbon fiber by physical sputtering, and then the carbon fiber with the SiC coating on the surface was braided into a three-dimensional braided carbon fiber with a braiding angle of 20 degrees.

[0036] Then, the three-dimensional braided carbon fiber with a volume percentage content of 10% is fixed in the mold and poured into a metal liquid smelted from a copper alloy with a volume percentage content of 90% to obtain a semi-finished three-dimensional braided carbon fiber / copper alloy composite material. Among them, the copper alloy is composed of the following components (by mass percentage): Ni: 2.0%, Si: 0.5%, Zn: 2.0%, P: 0.01%, Fe: 0.01%, Zr: 0.05%, rare earth elements: 0.1% , Pb: 0.01%, Bi: 0.001%, and the balance is Cu and unavoidable impurity elements. The semi-finished product was kept under pressure at 0.12MPa for 25 minutes, and then taken out for heat treatment. The heat treatme...

Embodiment 2

[0039] First, a SiC coating with a thickness of 0.8 μm was formed on the surface of the carbon fiber by physical sputtering, and then the carbon fiber with the SiC coating on the surface was woven into a three-dimensional woven carbon fiber through three-dimensional five-way mixing with a braiding angle of 25 degrees.

[0040] Then, the three-dimensional braided carbon fiber with a volume percentage content of 9% is fixed in the mold and then poured into a metal liquid smelted from a copper alloy with a volume percentage content of 91% to obtain a semi-finished three-dimensional braided carbon fiber / copper alloy composite material. Among them, the copper alloy is composed of the following components (by mass percentage): Ni: 2.5%, Si: 0.6%, Zn: 2.1%, P: 0.02%, Fe: 0.02%, Zr: 0.08%, rare earth elements: 0.2% , Pb: 0.01%, Bi: 0.001%, and the balance is Cu and unavoidable impurity elements. The semi-finished product was kept under pressure at 0.13MPa for 22 minutes, and then take...

Embodiment 3

[0043] First, a SiC coating with a thickness of 1 μm was formed on the surface of the carbon fiber by physical sputtering, and then the carbon fiber with the SiC coating on the surface was woven into a three-dimensional woven carbon fiber through three-dimensional five-way mixing, with a braiding angle of 28 degrees.

[0044] Then, the three-dimensional braided carbon fiber with a volume percentage content of 8% is fixed in the mold and poured into a metal liquid smelted from a copper alloy with a volume percentage content of 92% to obtain a semi-finished three-dimensional braided carbon fiber / copper alloy composite material. Among them, the copper alloy is composed of the following components (by mass percentage): Ni: 2.8%, Si: 0.8%, Zn: 2.3%, P: 0.03%, Fe: 0.03%, Zr: 0.1%, rare earth elements: 0.3% , Pb: 0.01%, Bi: 0.001%, and the balance is Cu and unavoidable impurity elements. The semi-finished product was kept under pressure at 0.14MPa for 20 minutes, and then taken out f...

Abstract

The invention relates to a television closed circuit connector which comprises a connector body. The connector body is made of a three-dimensional woven carbon fiber / copper alloy composite material. The three-dimensional woven carbon fiber / copper alloy composite material comprises, by volume percentage, 5% to 10% of three-dimensional woven carbon fibers and 90% to 95% of copper alloy. The television closed circuit connector is made of the three-dimensional woven carbon fiber / copper alloy composite material and has the advantages of two materials of the carbon fibers and the copper alloy at the same time, and through the matching of the carbon fibers and the copper alloy, the electric conducting property, the heat conducting property and the mechanical property of the connector are improved to a great extent. The components of the copper alloy in the three-dimensional woven carbon fiber / copper alloy composite material are reasonably matched, so that the copper alloy has the excellent properties such as strength, hardness and stress relaxation resistance, and the electric conductivity is excellent and is over three times of the electric conductivity of tin-phosphor bronze alloy.

Description

technical field [0001] The invention relates to a connector, in particular to a television closed-circuit connector.
