    摘要: An electrical box cover for an electrical outlet box includes a back and four sides extending from the back. The back and the four sides define an interior of the box cover that is large enough to cover the exterior of the electrical outlet box. The box cover is made of a soft, flexible material that can be molded to a shape of the electrical outlet box and that has certain elastomeric qualities so that the box cover can be slipped on to the electrical outlet box and installed, thereby providing additional sound and fire protection to the electrical outlet box. The cover box may also include a flange surrounding the opening in the box cover to cover any gaps around the cutout of the wall. The box cover may include one or more knock-outs that correspond to one or more knock-outs in the electrical outlet box.

    摘要: An electrical junction box with a waterproof property where a box body and a lower cover are fitted to each other is provided. An electrical junction box includes a box body having a peripheral wall formed in a frame shape and a lower cover with which a lower opening portion of the box body is covered. A lower end portion of the peripheral wall is provided with a double wall portion in which an inner wall and an outer wall extending in a peripheral direction are arranged with a clearance therebetween. An insertion wall portion provided on a tip end portion of a peripheral wall of the lower cover is inserted between the inner wall and the outer wall. In such an electrical junction box, a flange portion that projects toward the outer wall is provided on a projecting end portion of the insertion wall portion of the lower cover.

    摘要: A branch box (100) includes: a branch portion (21) branching a power path (205A) into at least two branch paths (206A, 207A); a fuse (60) located on at least one of the branch paths; a conductive member (33) connecting the branch portion and the branch path having the fuse; a first housing portion (11) receiving the fuse and closing its opening with a lid portion (81) to define a housing space; and a second housing portion (12) receiving the branch portion. The first housing portion is sealed with a first sealing material (85) filling a gap between the lid portion and the opening and is out of contact with the fuse. The second housing portion is sealed with a second sealing material (86) independent from the first sealing material. The conductive member passes through a partition wall (25) separating the first housing portion and the second housing portion.
