Problems solved by technology

[0003] However, in the above configuration, when rain, cleaning, etc. cause water droplets to immerse into the box, the water droplets sometimes wet the upper surface of the middle box or the bottom surface of the middle box.
In this way, there is a risk of short circuit between multiple terminals arranged on its upper surface or bottom surface

no. 1 approach

[0033] Referring to Figure 1 to Figure 5 A first embodiment of the present invention will be described.

[0034] FIG. 1 is an external perspective view of an electrical connection box 1 of the present embodiment. FIG. 2 is a perspective view showing a state before the frame body 21 and the lower connection body 40 are assembled on the circuit configuration body 10 .

[0035] Hereinafter, regarding the direction of each component constituting the electrical connection box 1, the left front side (cover 30 side) in FIG. , The bottom side is the bottom, the right side is the right side, and the left side is the left side.

[0036] Electrical junction box 1, as shown in Figure 1 and Figure 2, will have the circuit structure body 10 of circuit board 11 and bus bar (bus-bar) 12, vertically place and accommodate in the box body 20 that is made of frame body 21 and radiator plate 22 and cover the front side of the box body 20 with a cover 30 .

[0037] The circuit board 11 constitu...

no. 2 approach

[0072] Referring to Fig. 6, Fig. 7, Figure 8 A second embodiment of the present invention will be described.

[0073] 6 is a perspective view showing a state before the frame body 21 and the lower connector 40 are assembled to the circuit structure 10 in the electrical connection box 60 according to the second embodiment. FIG. 7 is a side sectional view of an electrical connection box 60 according to the second embodiment. Figure 8 It is a partially enlarged cross-sectional view showing a state in which the horizontal portion 16A of the lower bus bar terminal 16 is sandwiched between the first rib 45 and the second rib 58 in the electrical junction box 60 according to the second embodiment.

[0074] The electrical junction box 60 according to the second embodiment differs from the electrical junction box 1 according to the first embodiment in that the narrow portion 18 is provided on the horizontal portion 16A of the lower bus bar terminal 16 . The other configurations are...

no. 3 approach

[0083] A third embodiment of the present invention will be described below with reference to FIG. 9 .

[0084] FIG. 9 is a side sectional view of an electrical connection box 70 according to the third embodiment.

[0085] The electrical junction box 70 according to the third embodiment is different from the first embodiment or the second embodiment in that the displacement restricting portion 55 is not provided at the lower portion of the waterproof wall 50 . That is, in the third embodiment, the displacement restricting portion 55 that restricts the upward displacement of the horizontal portion 16A by pressing the horizontal portion 16A of the lower bus bar terminal 16 from above is not provided. In addition, the other configurations are the same as those of the first or second embodiment, so the same reference numerals are used, and repeated descriptions are omitted.

[0086] When the lower connector 40 of the electrical junction box 70 is fitted with an external connector,...

Abstract

An electric connection box provided with a circuit structure, a casing for accommodating the circuit structure therein, a plurality of bus bar terminals disposed on a cabling path crossing the casing in a horizontal direction and electrically connecting the circuit structure and an external connecter to each other, and a terminal support portion for supporting a horizontal portion crossing the casing in the horizontal direction in the plurality of bus bar terminals from below, in which a first rib capable of contact with the horizontal portion from below are projected on a surface opposite to the horizontal portion in the terminal support portion, and a space between the first rib is a first groove portion recessed downward.

Description

technical field [0001] The invention relates to an electrical connection box. Background technique [0002] A device described in JP-A-2004-40873 is known as an electrical connection box mounted on an automobile or the like. The electrical connection box has a circuit substrate joined with a bus bar and a box body for accommodating the circuit substrate. In addition, a plurality of fuse connection terminals and signal terminals are formed in the bus bar. The fuse connection terminal is arranged to extend from the upper end of the circuit board and along the upper end surface of the intermediate case provided in the case, and is formed so as to protrude upward at its tip. On the other hand, the signal terminals are arranged so as to extend from the lower end of the circuit board along the bottom surface of the intermediate case, and are formed so that their top ends protrude downward. [0003] However, in the above configuration, when water drops enter the housing due to r...
