Embodiment Construction

[0050] A first embodiment of the present invention will be described below with reference to the drawings.

[0051] Such as Figures 2 to 4 As shown, an electrical junction box 1 includes: a first busbar 2; a busbar installation body 4, on which a second busbar 3 is installed; an inner cover 5, which is installed on the busbar installation body 4 and Covering the relay part 6; a housing 7, which accommodates the first bus bar 2, the bus bar mounting body 4 and the inner cover 5; a fuse chamber 8, which is installed to the upper side of the housing 7; and four fuses 9, which It is mounted on the fuse terminals 11 and 18 which are provided in the fuse cavity 8 in a protruding state. Figure 4 The arrow 30 in the arrow 30 shows the direction in which water droplets W entering the case 7 through the fuse mounting portion 8 b are discharged through the drain channel in the electrical junction box 1 .

[0052] The first bus bar 2 is manufactured by press-forming a rigid hard condu...

Abstract

A relay part is housed in a case, a fuse mounting part is provided above the relay part in the case and a fuse is attached / detached to / from the fuse mounting part from above the case. In the case, provided are an internal cover and a bus bar supporting resin body, which cover the periphery of the relay part. A drainage channel is provided in outer surfaces of the internal cover and the bus bar supporting resin body. In addition, a drainage hole which drains water flowing through the drainage channel to the outside of the case is provided in the case. The drainage channel includes an upper groove which is formed in an upper surface of the bus bar supporting resin body and has an inclined surface on its bottom and a side groove which is communicated with a lowest portion of the inclined surface of the upper groove and is formed on a side of the internal cover.

Description

[0001] The patent application for the present invention is a divisional application of the patent application for invention with the application number 200410035392.1 and the title of the invention as "electric junction box". technical field [0002] The present invention relates to an electrical junction box in which fuse and relay components are housed. Background technique [0003] A conventional electrical junction box is disclosed in German Patent Application Publication No. 3209915. As shown in FIG. 1 , in this electrical junction box 50 , a relay unit 52 is accommodated in a case 51 . In the case 51 , a fuse mounting part 53 is provided above the relay part 52 . The fuse 54 can be freely attached to or detached from the fuse attachment member 53 from the above-mentioned case 51 . [0004] The electric junction box 50 described above has an advantage that the state of the fuse 54 can be checked and the fuse 54 can be replaced from the case 51 described above. [000...
