Abstract

PURPOSE:To improve workability and reliability of maintenance and outfit wiring by connecting a conductor connected to an electric car control unit to an outfitting cable through a terminal block in an outfitting wiring duct so as to enlarge a space in a box. CONSTITUTION:A terminal block 5 is mounted on the upper face in a cylindrical outfitting wiring duct receiver 6c. And when a conductor 3 connected to an electric car control unit 4 in a box 6 is connected to an outfitting cable 4 arranged in an outfitting wiring duct 8, a small duct lid 12 is removed without removing a large side cover 7 and the conductor 3 and the outfitting cable 4 are mounted on a connection terminal part of the exposed terminal block 5 with a mounting screw 5a for connection. At maintenance work, by removing the small duct lid 12 without removing the large side cover 7, maintenance is done at the connection terminal part of the exposed terminal block 5. Thus, maintenance and outfitting wiring work can be done outside the body and workability can be improved.

It is composed of a terminal block 5 and a housing 6 for housing them. In addition, in the housing 6,
Openings 6a formed on both sides for maintenance and inspection
A side cover 7 for sealing the wire is detachably provided in the opening 6a with a mounting screw (not shown) or the like, and is provided on the outer surface of the peripheral edge of the wiring hole 6b formed in one upper part of both side surfaces thereof. Is provided with a tubular fitting wiring duct receiver 6c.

The electric vehicle control device 1 configured as described above
Is, for example, substantially at the center of the electric vehicle 10 in the longitudinal direction as shown in FIG. 6, and as shown in FIG.
No. 0 below the floor, the fitting wiring ducts 8 arranged in the center of the width direction of the vehicle body 11 are sandwiched, and they are arranged on both sides of the equipment wiring duct 8 and are attached to the vehicle body 11 by the attachment bases 9. Then, as a countermeasure against inductive obstacles, the equipment wiring duct 7 is connected to the equipment wiring duct receiver 6c with its inner surface in contact with the outer surface of the equipment wiring duct receiver 6c. The outfitting electric wire 4 arranged in the outfitting wiring duct 7 passes through the wiring hole 6b and the mounting screw 5a together with the conductor 3.
Then, it is clamped and fixed to the connection terminal portion (not shown) of the terminal block 5 and connected to the conductor 3. In this way, the terminal block 5 is arranged above the electric vehicle unit 2 in the housing 6 in order to connect the outfitting electric wire 4 and the conductor 3. The conductors 3 that connect the electric vehicle control units 2 and 2 arranged below the terminal block 5 and that connect the electric vehicle control unit 2 and the outfitting electric wires 4 are arranged in the wiring space in the upper part of the housing 6. It

[0004]

Since the conventional electric vehicle controller is constructed as described above, there is a space near the terminal block 5 in the housing 6 for wiring connection work and maintenance and inspection work. Although necessary, since the electric vehicle control device is attached to the lower portion of the vehicle body 5, the outer dimensions of the housing 6 are limited and the above space is taken, so that the housing 6 cannot be enlarged. Therefore, the electric vehicle control unit 2 below the terminal block 5 requires a cut 2a as shown in FIG. 4, which complicates the structure of the electric vehicle control unit 2 and the arrangement of the electric vehicle control unit 2 in the housing 6, and the electric vehicle control device. Since maintenance and inspection as well as outfitting and wiring work must be carried out with the vehicle 1 mounted on the vehicle body 11, the large side cover 7 must be removed during the above maintenance and inspection and outfitting and wiring work, and the electric vehicle control unit 2 However, there is a problem that it is difficult to work because it is necessary not to hit a tool etc.

The present invention has been made in order to solve the above problems, and can be installed in a housing without forming a cut as a space for inspection or outfitting wiring work in an electric vehicle control unit. An object of the present invention is to provide an electric vehicle control device which can be inspected and equipped with wiring without removing a large side cover and has good workability.

[0006]

An electric vehicle control device according to the present invention has an outfitting wiring duct receiver formed on a side surface of a housing attached to a lower portion of a vehicle body of an electric vehicle, and the outfitting wiring engaging with the above outfitting wiring duct receiver. In an electric vehicle control device in which an outfitting electric wire arranged in a duct and an electric vehicle control unit housed in the housing are electrically connected via a terminal block, the terminal block is provided with the outfitting wiring. It is arranged in the duct.

[0007]

With the electric vehicle control device according to the present invention, inspection and outfitting and wiring work can be performed outside the housing, and workability is improved. In addition, a space for inspection and outfitting and wiring work inside the housing is not required, and the electric car control unit can be cut. The structure is simplified without the need for the above, and the electric vehicle control unit can be efficiently arranged in the housing.
