Description

  The present invention relates to an electrical component for an industrial vehicle or a construction vehicle, an electrical wiring, and a fixture for hydraulic piping.

  Conventionally, in industrial vehicles such as forklifts and construction vehicles such as excavators, various fixing devices for hydraulic pipes and fixing devices for electric wiring are known (for example, Patent Documents 1 to 5). Due to the layout of vehicle components such as engine parts, electrical wiring and hydraulic piping may be passed to the left and right of the vehicle. In such a case, electrical wiring and hydraulic piping are routed independently. If they are installed, their installation work becomes complicated, and when electrical components or electrical wiring and hydraulic piping are stretched close to each other, depending on the arrangement relationship, for example, oil leaked from the hydraulic piping adheres to the electrical wiring. This may cause a fire.

It is fixed to the suspension plate 2 by screwing so as to straddle the electric wiring C placed thereon.

  Since the suspension plate 2 is formed with the guide plate portion 2e, the electrical wiring C is less likely to drop off when the electrical wiring C is placed on the suspension plate 2. Further, since the foot pieces 12a, 12b and the foot pieces 12c are fixed so as to straddle the electric wiring C, the electric wiring C is placed on the suspension plate 2 even if it is not fixed on the suspension plate 2. Only can prevent the dropout. Further, the electrical wiring C is further stabilized on the suspension plate 2 by guiding the electrical wiring C along the longitudinal direction of the guide surface 3b.

  Since the foot pieces 12a and 12b are engaged with the male recessed portions 7 protruding outward from the guide plate portion 2e by engaging the engaging concave portions 13 formed at the respective lower end portions from above. Mounting is easy, and even before fixing with the nut 8, the standing plate 3 is easy to stand on its own and is not easily toppled, so that it is easy to fix the standing plate 3 to the suspension plate 2.

  In addition, the electrical components 9 to 11 and the electrical wiring C fixed to the fixture 1 in this way are separated from the hydraulic piping P by the suspension plate 2, and the hydraulic piping P is connected to the electrical components 9 to 11 and the electrical components. Because it is placed under the wiring C, oil that has oozed out from the joints of the hydraulic piping P due to age deterioration etc. does not adhere to the electrical components 9 to 11 and the electrical wiring C, thus reducing the risk of fire. can do.
