Each of the terminals, which terminals are attachment targets , is interposed between the nut 92 and the lower section 91a, and a female screw is formed on a su internal circumferential surface. That is, when the nut 92 is screwed onto the stud / set screw 91, the rotation of the lower section 91a about the shaft 91b in association with the nut 92 is regulated and therefore in order to regulate the rotation of the stud 91, the stud 91 is not retained by means of afferent means. As a result, it is possible to easily attach the fastening elements 9A and 9B.
    Next, an example of the assembly of the relay box and fuses 1 according to the present embodiment will be described. First, an operator causes the power distribution unit 3 which is attached to the cover member 25 to face the first containment space 2b so that the first electronic component 33 faces the wall 22, and it inserts the power distribution unit 3 inside the first capacity space 2b from the first opening section 21a in the X direction. Here, when the operator inserts the distribution unit of power 3 within the first capacity space 2b, the operator inserts the tip section of the first power source input terminal 32 which is positioned within the first capacity space 2b to the 22b and it positions the tip section inside the second capacity space 2c. Then, the operator inserts the shaft 91b into the through hole 32b of the first power source input terminal 32 which is positioned within the second capacity space 2c so that the lower section 91a of the stud 91 is on the side of the first substrate 31. Moreover, when the operator inserts the power distribution unit 3 inside the first capacity space 2b, the operator inserts the first section of the adaptation 51 within the through hole 22a and positions a portion of the first matching section 51 within the second capacity space 2c. Then, in the case where the operator further inserts the power distribution unit 3 within the first capacity space 2b in the X direction, the first capacity space 2b is blocked / blocked by means of the cover member 25, and the power distribution unit 3 is contained within the containment space 2a. At this time, at the first power source input terminal 32, the first exposed terminal section 32a is contained within the terminal capacitance space 23c which is formed on the outside of the main body section 21, in association with the stud 91 in a state in which the shaft 91b is inserted into the through hole 32b. Here, the cover member 25 is engaged with the main body section 21 by means of an engagement mechanism (not shown) or the like.
    Then, the operator causes the voltage conversion unit 4 which is attached to the heat sink element 6 to face the second capacity space 2c so that the second electronic component 44 faces the wall 22, and inserts the power / voltage conversion unit 4 within the second capacity space 2c from the second opening section 21b in the X direction. Next, the operator inserts the shaft 91b. within the through hole 42b of the second power source input terminal 42 such that the lower section 91a of the stud 91 is on the side of the second substrate 41. Then, in the case where the operator further inserts the power / voltage conversion unit 4 within the second capacity space 2c in the X direction, the second capacity space 2c is blocked / obstructed by the heat dissipation element 6, and the unit tens conversion ion 4 is contained within the containment space 2a. At this time, at the second power source input terminal 42, the through hole 42b is inserted on the shaft 91b on which the through hole 32b is inserted, and the second terminal exposed section 42a is contained in FIG. the inside of the terminal capacitance space 23c which is formed on the outside of the main body section 21. Furthermore, at the charge output terminal 43, the exposed charge terminal section 43a is contained within the terminal containment space 24c which is formed on the outside of the main body section 21, in association with the stud 91 in a state in which the shaft 91b is inserted through the through hole 43b. Moreover, the second fitting / connecting section 52 is inserted within the opening section of the first matching section 51, which section is positioned within the second holding space 2c, and the second matching section 52 is connected / fitted inside the first matching section 51. Here, the heat dissipating element 6 is engaged with the main body section 21 by means of a mechanism commitment (which is not represented) or similar.
    Then, the operator inserts the ring section 71 of the power source connection terminal 7 on the shaft 91b of the stud 91 which is contained within the terminal capacity space 23c, and inserts the ring section 81 of the load connection terminal 8 on the shaft 91b of the stud 91 which is contained within the terminal capacity space 24c.

Therefore, even in the case in which each of the terminals 32, 42 and 7 generates heat, it is possible to release / discharge the heat outside the housing 2 via the first exposed section of terminal 32a and the second exposed terminal section 42a. Therefore, it is possible to attenuate or even eliminate an increase in the temperature inside the housing 2, compared to the case in which each of the terminals 32, 42 and 7 is attached to the interior of the housing. 2.
    Moreover, the first power source input terminal 32 and the second power source input terminal 42 are electrically connected directly to a single power source connection terminal 7. power distribution 3 is arranged to be separated from the voltage conversion unit 4 and consequently, it is possible to reduce the number of electrical cables / wires that are connected to the power source connection terminal 7 and to the power source such that this number is equal to the unit, as compared with the case in which each terminal of the first power source input terminal 32 and the second source input terminal power 42 is connected to the power source. As a result, it is possible to reduce the weight of a bundle of cables (W / H) including the relay box and fuses 1 or simplify its operation of routing the various cables. Moreover, the first power source input terminal 32 and the second power source input terminal 42 are directly connected to the power source connection terminal 7 by means of the attachment member 9A and as a result, a wire / electrical cable that is routed between the first power source input terminal 32 and the second power source input terminal 42 is not required. Therefore, it is possible to suppress a power loss due to the resistance of the electric wire itself, as well as to improve the performance of the relay box and fuses 1.
    Moreover, the load output terminal 43 is exposed outside the housing 2 and is attached to the load connection terminal 8 which is connected to the power source by means of the attachment member 9B and therefore, even in the case in which each of the terminals 43 and 8 generates heat due to the power that is supplied / applied from the power source, it is possible to release / evacuate the heat outside the housing 2 via the exposed charging terminal section 43a. Therefore, it is possible to attenuate or even eliminate an increase in the temperature inside the housing 2, compared to the case in which each of the terminals 43 and 8 is attached to the interior of the housing 2.
    Moreover, the exposed first terminal section 32a, the second exposed terminal section 42a and the exposed charging terminal section 43a are exposed outside the housing 2 and therefore, it is possible for the operator to perform easy maintenance / intervention at the relay box and fuses 1, such as its attachment or removal, and it improves its working efficiency in relation to the relay box and fuses 1.

Thus, the first electronic component 33 and the second electronic component 44 are arranged on an air layer between the first substrate 31 and the second substrate 41. The conductivity The thermal temperature of the air is lower than the thermal conductivity of a solid such as a resin or a metal that configures the power distribution unit 3 and the voltage conversion unit 4 and therefore it It is possible to attenuate or even eliminate the thermal interference between the power distribution unit 3 and the voltage conversion unit 4 in the case in which the power distribution unit 3 and the conversion of voltage 4 produce heat.
    Moreover, within the main body section 21 according to the present embodiment, the partition wall 22 is formed within the containment space 2a, but the configuration is not limited to this building arrangement, and the partition wall 22 may not be disposed. In this case, the first electronic component 33 faces the second electronic component 44 in the X direction and therefore it is possible to arrange the second electronic component 44 within a space in which the first electronic component 33 is not mounted.
