Description

  The present invention relates to a vehicular electrical component container that houses an electrical component that supplies electric power to a drive unit of a vehicle and a power feeding cable.

  Conventional vehicles are mainly gasoline vehicles driven with gasoline as fuel, and members that use high-voltage power in the vehicles are limited. However, in the case of an electric vehicle or a hybrid vehicle that uses an electric motor as a driving force, it is driven using electric power stored in a power storage device such as a secondary battery mounted on the vehicle, so an opportunity to use a member that uses high-voltage power Accordingly, countermeasures such as electric leakage, short circuit, electric shock, etc. are required.

  As a safety measure for such a component that uses high-voltage power used in a vehicle, for example, Patent Document 1 discloses a battery pack including a buffer portion that absorbs an impact. The battery pack includes a module assembly (battery) and an exterior member (battery cover) that covers the module assembly, and the battery cover includes a buffer portion. The buffer portion is provided so as to face the conductive member (terminal, main battery cable, battery plug cable, harness) connected to the module assembly, and deforms in the thickness direction to absorb the impact. Thereby, since the impact from the outside is relieved by the buffer portion, it is possible to prevent the impact from being directly transmitted to the conductive member and short-circuiting.

  The charging device 30 is fixed to the frame 22 and controls charging of a secondary battery provided in the vehicle 1. The secondary battery stores electric power supplied from an external power source and supplies electric power to the electric motor or the like of the vehicle 1.

  The service plug device 40 is a circuit shut-off component for shutting off the power supply circuit when performing an inspection operation or the like of an electrical component that is supplied with electric power from the charging device 30. It is configured. The charging device 30 and the power supply harness 50 are connected via the service plug device 40. When the service plug 41 is inserted into the service plug insertion port 42, the electric circuit is energized, and the service plug 41 is connected. In the state where it is not inserted into the service plug insertion port 42, the electric circuit is cut off. That is, the service plug device 40 can be switched between a state in which power is supplied to the power supply harness 50 and a state in which the power supply harness 50 is not supplied by an operation of attaching and detaching the service plug 41.

  The service plug insertion port 42 is provided at a position directly below the opening 23 of the protective cover 21, and the opening 23 is formed slightly larger than the service plug 41. Thereby, without removing the protective cover 21 from the electrical component case 2, the operator can insert and remove the service plug 41 by inserting a finger from the opening 23.

  As shown in FIG. 4, the power supply harness 50 includes a plurality of power supply cables 50 a, 50 b, 50 c, 50 d, and 50 e that are arranged horizontally. From the charging device 2 to various electric devices of the vehicle 1 such as an electric motor. To supply power. Terminals 51, which are connection portions with other electrical components, are provided at the ends of the power supply cables 50a to 50e. The terminal 51 from which the conductor is exposed becomes a live part when energized.

  Further, as shown in FIG. 5, the side and upper side of the power supply harness 50 housed in the electrical component case 2 are covered with a cable protector 60 to protect the power supply harness 50 from impact and to prevent electromagnetic waves. Noise is prevented from leaking outside. The cable protector 60 is a plate-like member that is provided on both sides of the power supply harness 50 and that is a plate-like member that extends vertically and connects the upper ends of the side-wall portions 61 and extends in parallel with the protective cover 21. A certain ceiling portion 62 is included. The lower end portion of the side wall portion 61 is fixed to the bottom plate 25 of the electrical component case 2, and the power supply harness 50 is held by the electrical component case 2 by being covered with the cable protector 60.

  As shown in FIG. 6, the cable protector 60 is formed larger than a size necessary for covering the power supply harness 50. That is, the height of the side wall portion 61 is formed higher than the height of the power supply harness 50 (the height of the cable having the largest cross-sectional area among the power supply cables 50a, 50b, 50c, 50d, and 50e). . In addition, the width of the ceiling portion 62 (the length in the width direction of the power supply harness 50) is formed wider than the width of the power supply harness 50 (a total width of the power supply cables 50a, 50b, 50c, 50d, and 50e). ing. The ceiling portion 62 of the cable protector 60 is not formed above each terminal 51 of the power supply harness 50. Therefore, it is possible to perform connection confirmation of each terminal 51, connection work, and the like without removing the cable protector 60 from the electrical component case 2.

  Since the cable protector 60 is thus formed large, the interior of the electrical component case 2 is an electrical component except for the periphery of the terminal 51 of the power supply harness 50 as shown in FIGS. 4 and 5. The charging device 30, the service plug device 40, and the cable protector 60 are arranged with almost no gap. The arrangement is such that there is almost no gap between the ceiling 62 and the protective cover 21. Therefore, the interior of the electrical component case 2 is covered with the cable protector 60 except for the periphery of the terminal 51 of the power supply harness 50 and the portion where the charging device 30 and the service plug device 40 are disposed. Here, the terminal 51 is provided at a position slightly away from the service plug device 40, and the cable protector 60 is disposed between the terminal 51 and the service plug device 40. Moreover, the ceiling part 62 of the cable protector 60 is formed higher than the power supply harness 50 so that there is almost no gap with the protective cover 21 (see FIG. 6). Therefore, in the electrical component case 2, the space between the terminal 51 and the service plug device 40 is partitioned by the side wall portion 61 and the ceiling portion 62 of the cable protector 60.

  Next, an inspection / maintenance operation of each electrical component housed in the electrical component case 2 by the operator will be described. First, an operator performs an operation of interrupting an electric circuit in the electric component case 2 in order to prevent an electric shock or a leakage due to contact with the electric component in the electric component case 2. The operation of cutting off the electric circuit is performed by inserting a finger or the like into the opening 23 formed in the protective cover 21 and operating the service plug device 40 provided directly below the opening 23. That is, the service plug 41 is removed from the service plug insertion port 42 and taken out from the opening 23. Thereby, it will be in the state by which electric power is not supplied to each electrical component from the charging device 30. FIG.

  When the electric circuit in the electric component case 2 is interrupted, the operator removes the protective cover 21 from the electric component case 2 and inspects and maintains each electric component. At this time, since electric power is not supplied to the power supply harness 50, even if an operator contacts the terminal 51, no electric shock or electric leakage occurs.

  When the inspection and maintenance of each electrical component is completed, the protective cover 21 is returned to its original state, and the state in which the upper surface of the electrical component case 2 is covered with the protective cover 21 is restored. Then, the service plug 41 is inserted into the opening 23 and attached to the service plug insertion port 42. As a result, the electric circuit in the electric component case 2 is energized, and power is supplied from the charging device 30 to each electric component.

  Thus, the electrical circuit of the electrical component in the electrical component case 2 is shut off before the protective cover 21 is removed by the opening 23 provided directly above the service plug device 40, and the protective cover 21 is attached. Later, the electrical circuit can be energized. Therefore, it is possible to prevent leakage, short circuit, electric shock, etc. during inspection and maintenance work of each electrical component in the electrical component case 2.

  On the other hand, even when the protective cover 21 is attached, for example, a bolt or the like falls into the opening 23 during the work of removing the service plug 41, and foreign matter enters the electrical component case 2 from the opening 23. There is a risk that. In this case, in a state where the electrical circuit in the electrical component case 2 is energized, each terminal 51 of the power supply harness 50 becomes a live part, and when an invading foreign object comes into contact, leakage, short circuit, electric shock, etc. occur. End up. However, the space between the terminal 51 and the service plug device 40 is partitioned by the cable protector 60. Therefore, even if foreign matter enters the electrical component case 2 from the opening 23, the side wall portion 61 and the ceiling portion 62 of the cable protector 60 serve as a barrier so that the foreign matter cannot reach the terminal 51.

  As described above, the protective cover 21 covering the upper surface of the electrical component case 2 is provided with the opening 23 for operating the service plug device 40, so that the protective cover 21 is attached to the electrical component case 2. The electric circuit in the electric component case 2 can be switched between a cut-off state and an energized state. Even if foreign matter enters from the opening 23, the cable protector 60 that covers the power supply harness 50 can serve as a barrier to prevent foreign matter from reaching the terminal 51.

  In the present embodiment, the opening 23 is formed directly above the service plug device 40 so that the service plug device 40 can be operated with the protective cover 21 attached. For example, the opening may be used for operating other electrical components such as a power switch of the charging device.

  In the present embodiment, the cable protector 60 is formed larger than the size necessary for covering the power supply harness 50, and the terminal 51 and the service plug device 40 are connected by the side wall portion 61 and the ceiling portion 62 of the cable protector 60. The space between them is partitioned. However, the present invention is not limited to this, and the cable protector 60 has a size that only covers the power supply harness 50, and partitions the space between the terminal 51 and the service plug device 40 on the side wall portion 61 and the ceiling portion 62 of the cable protector 60. You may make it provide a convex part and a partition plate.
