[0004] However, the prior art electrical junction box has a structure integrated with electrical parts and circuit substrates
Therefore, the entire electrical junction box must be designed and manufactured every time the installation specifications of the electrical parts or the circuit substrate are changed, resulting in high cost of the electrical junction box

Embodiment Construction
[0012] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. figure 1 is an exploded perspective view showing an electrical junction box and its ground connection structure according to the embodiment. figure 2 A is a sectional view showing the state before the inner box is accommodated in the outer box, and figure 2 B is a sectional view showing a state after the inner box is housed in the outer box.
[0013] Such as figure 1 , 2 As shown in A and 2B, the electrical junction box 5 in this embodiment is to be fixed by bolts 2 to the body 1 of an automobile as a fixing target, and is divided into both an outer box 10 and an inner box 30 .
[0014] The outer box 10 is configured to be fixed directly to the vehicle body 1 (an example of a fixing target). The inner box 30 is configured to be detachably accommodated in the outer box 10 . Electrical components such as relays and fuses and circuit s...

An electrical junction box includes an outer box and an inner box accommodated in the outer box. The outer box includes: an outer box body; a first locking part, which locks the inner box; and a grounding part, which is electrically connected to a grounding conductor, and the grounding part includes a first ground contact part, which is arranged at the first locking part or connected to the first The locking portions are adjacent. The inner box includes: an inner box body; a second locking portion engaged with the first locking portion; a ground circuit element to which the circuit base is connected to ground the circuit base; and a contact conductor electrically connected to the ground In the circuit component, the contact conductor includes a second ground contact portion, and when the first locking portion and the second locking portion engage with each other, the second ground contact portion is electrically connected to the first ground contact portion.
Description
technical field [0001] The invention relates to an electric junction box installed on a vehicle and its ground connection structure. Background technique [0002] An electrical junction box that connects the battery to various electrical devices is mounted on the vehicle (see, for example, JP2013-226019A). Electrical components (relays, fuses, etc.) and circuit substrates (circuit boards, bus bars, etc.) are installed on the electrical junction box. [0003] The ground conductor is provided in a part of the circuit base, and many ground conductors are connected to a ground point outside the electrical junction box through wires such as electric wires in an appropriately aggregated form. Alternatively, the ground circuit is incorporated into the connector of the electrical junction box such that the ground conductor is grounded through the ground circuit of the mating connector. [0004] However, the prior art electrical junction box has a structure integrated with electric...
