Embodiment 1
[0030] combine figure 1 , a carbon fiber graphite grounding body in this embodiment, comprising a core 1 formed by parallel arrangement of graphite wires, a plurality of graphite wires are braided to form a braided conductive layer 2 on the periphery of the core 1, and one end of the carbon fiber graphite grounding body is fixed with a first metal fixing member 3. The other end is fixed with a second metal fixing part 4; the first metal fixing part 3 is formed with a fixing hole 5, and the second metal fixing part 4 is protrudingly formed with spikes 6, and the number of spikes 6 is not less than two.
[0031] The production method of graphite wire is as follows: carbon fibers are bonded into a row through the first conductive adhesive; graphite is expanded through an expansion furnace to obtain graphite worms; the upper and lower sides of the carbon fiber are respectively compounded with graphite worms, and then pressed by a pressure roller to form graphite paper. After the gr...
Embodiment 2
[0035] In order to prevent the first metal fixing part 3 and the second metal fixing part 4 from being corroded, the surfaces of the first metal fixing part 3 and the second metal fixing part 4 are coated with a conductive anti-corrosion layer.
[0036] The conductive anticorrosion layer includes graphite, resin and second conductive glue. Wherein, the mass ratio of graphite, resin and second conductive glue is: 7:2:1.
[0037] The second conductive glue includes 40-60 parts by weight of epoxy resin, 30 parts by weight of graphite powder, 10-30 parts by weight of diluent and 1.5-3 parts by weight of amine curing agent.
[0038] Since the main component of the second conductive adhesive is graphite, it has good electrical conductivity and heat dissipation capability, and the second conductive adhesive increases adhesion.
Embodiment 3
[0040] A method for making a carbon fiber graphite grounding body, comprising the steps of:
[0041] Step 1. Making graphite wire: carbon fibers are bonded into a row through the first conductive adhesive; graphite is expanded through an expansion furnace to obtain graphite worms; the upper and lower sides of the carbon fiber are respectively compounded with graphite worms, and then pressed by a pressure roller to form graphite paper, and the graphite paper is cut into strips After winding, the graphite wire is obtained;
[0042] Step 2: According to the product specifications, a number of graphite wires are arranged in parallel to form a wire core 1, and graphite wires are used outside the wire core 1 to form a braided conductive layer 2 to form a carbon fiber graphite grounding body;
[0043] Step 3: making conductive anticorrosion layer;
[0044] Step 4: Apply a conductive anti-corrosion layer on the surface of the first metal fixing part 3 and the second metal fixing part...
