Embodiment 1

[0132] 1. Make the conduction parts

[0133] (1) Preparation of multilayer carbon nanotubes

[0134] As mentioned above, the multilayered carbon nanotubes of the present invention are obtained by annealing the intermediate body produced by heating at a temperature of 800 to 1300°C at a high temperature of 2400 to 3000°C. The preferred preparation method is described in detail.

[0135] Although not particularly limited, when producing the above-mentioned carbon fiber structure, it is preferable to use at least two or more carbon compounds having different decomposition temperatures as carbon sources. The so-called at least two or more carbon compounds here do not necessarily use two or more substances as raw organic compounds. Reaction such as hydrodealkylation (hydrodealkylation) of toluene or xylene, which turns into two or more kinds of carbon compounds with different decomposition temperatures in the subsequent thermal decomposition reaction system is also included. Fur...

Embodiment 2

[0148] Multilayered carbon nanotubes were produced in the same manner as in Example 1, and conducting members were produced in the same manner as in Example 1 except that 15 parts by weight of the obtained multilayered carbon nanotubes were used. The transfer characteristics of the obtained conduction member were evaluated in the same manner as in Example 1. The results are shown in Table 1. In the transfer characteristics, a further improvement in performance was observed.

Embodiment 3

[0150] In addition to using 10 parts by weight of carbon nanofiber [VGCF (registered trademark), Showa Denko Co., Ltd.] synthesized by the gas phase method instead of the multilayer carbon nanotube used in Example 1, the others are the same as in Example 1. Conductive parts were fabricated. The transfer characteristics of the obtained conduction member were evaluated in the same manner as in Example 1. The results are shown in Table 1. Compared with the conduction member of Example 1, the transfer characteristic was slightly inferior, but it was still at a level that could be used as a conduction member.

Abstract

A conductive member composed of a conductive resin transmits a signal by being conductively connected with a body to be connected. The conductive resin includes fiber nanocarbon in the resin.

Description

technical field [0001] The present invention relates to a conducting member and a contact device using the conducting member, wherein the conducting member is formed of a conductive resin containing fibrous nanocarbon in the resin. Background technique [0002] Contact devices are used in a wide range of fields requiring electrical connection, and examples include contact devices used in glass antennas for vehicles. Conventionally, connectors have been used to connect such glass antennas to the body of the vehicle, but using connectors to connect is not only cumbersome, but also increases the number of parts and increases production costs. [0003] Figure 8 Shows an example of a conventionally used contact device. The contact device 70 has a fixed part 74 fixed on a part 72, a movable contact 76 formed by a conductor freely movably accommodated in the fixed part 74, and a movable contact 76 formed by a conductor also freely movably accommodated in the fixed part 74. The s...
