Description

This invention relates to an electrical connection box, such as a relay box or fuse box, which is mounted in a vehicle, such as an automobile, and houses a circuit board on which electronic components such as fuses and electronic control circuits are mounted. In vehicles such as automobiles, an electrical junction box is provided, for example, in the engine compartment, which houses a circuit board on which electronic components such as fuses and electronic control circuits are mounted within a junction box body (see Patent Document 1). Such electrical junction boxes are positioned, for example, between the battery and electrical equipment, and are connected to the battery and electrical equipment via wires. In this case, the wires are secured to a fixing point on the vehicle body using clamps or the like, for example, between the battery and the electrical junction box. Incidentally, in recent years, there has been a need to place electrical junction boxes close to the vehicle body and onboard components in order to make effective use of the limited space in vehicles. However, if the electrical junction box is placed too close to the vehicle body or onboard components, the wires routed to the junction box may come into contact with the vehicle body or onboard components, potentially causing unintended malfunctions. Therefore, it is conceivable to restrict the routing of the electric wires by providing a fixing point for the wires in the vicinity of the electrical junction box to avoid contact with the vehicle body or onboard components. However, in this case, there was a risk that no surrounding components suitable for providing a fixing point existed in a location appropriate for restricting the routing of the electric wires.
