Problems solved by technology

Therefore, the lower cover 103 must be coupled to the junction box body 101 when the installation position of the bellows C is predetermined, and this assembly operation must be performed while paying attention to the bellows and the lower cover, so the assembly operation appears troublesome.
In addition, when the position of the bellows C needs to be changed after the lower cover 103 is coupled to the junction box body 101, the lower cover 103 must be detached from the junction box body 101 again, and this operation is troublesome in this respect as well.

[0055]1 to 11 show the structure of the electrical junction box of the first embodiment. The electrical junction box includes a junction box body 10A for receiving a portion connected to an electric wire W (such as a relay, etc.), a lower cover 20A coupled to the junction box body 10A to cover the lower side of the junction box body 10A, and an upper A cover (not shown) is coupled to the junction box body 10A to cover the upper side of the junction box body 10A. An engaging portion 12 for locking engagement with the upper cover is formed on an outer wall (side wall) 11 of the junction box body 10A. Further, engagement portions (protrusions in the embodiment) 13 for locking engagement with engagement portions (frame-shaped engagement portions in the embodiment) 23 on the lower cover 20A, respectively, are formed on the outer wall 11 .

[0056] A first cutout 21 for wire drawing-out purpose is formed in the bottom wall 20a of the lower cover 20A. The second slit 22 is formed i...

[0068] 12 to 23 show the structure of the electrical junction box of the second embodiment.

[0069] The difference between the electrical junction box of the second embodiment and the electrical junction box of the first embodiment is that the cover 30B is not integrally connected with the junction box body 10B, but is integrally connected with the lower cover 20B. Therefore, the same constituent elements are denoted by the same reference numerals, respectively, and descriptions thereof are omitted.

[0070] That is, in the electrical junction box of the second embodiment, the cover 30B is pivotally connected to the side edge of the second cutout 22 in the lower cover 20B by the hinge (hinge portion) 31 so as to pivotally move left and right, and therefore, The cover 30B is integrally molded with the lower cover 20B.

[0071] Also in this case, when the electrical junction box is assembled, the lower cover 20B is coupled to the lower side of the junction box body 10B as show...

Abstract

An electrical connection box comprises: a main body for receiving the part to be connected to the wire; a lower cover connected to the main body for covering the lower part of the main body; a first notch formed in the lower cover; a second notch formed in the lower cover and connected with the first notch; a closure for opening and closing the second notch; surrounding walls formed on the lower cover and the closure respectively and defining the first notch as an opening when the closure is closed; and ridge portion formed on the inner surface of the surrounding walls of the lower cover and the closure respectively and installed in the ring concave portion in the periphery of a wire protective tube. The wire protective tube is installed on the wire and the wire is lead out by the first notch when the shield is closed.

Description

technical field [0001] The present invention relates to an electrical junction box (ie, an electrical connection box, or an electrical junction box) such as a relay box, a fuse box, etc. for mounting on a vehicle such as an automobile. Background technique [0002] When the electric wires are drawn out through the electric wire lead-out holes formed in the outer wall of the electrical junction box, relatedly, a corrugated tube (wire protection tube) is installed on the electric wires for the purpose of protecting the electric wires and also for the purpose of waterproofing, with convex / concave mounting The arranged waterproof structure is arranged between the bellows and the wire lead-out hole. [0003] FIG. 24 is a vertical sectional view of the electrical junction box described in Patent Document 1. FIG. The electrical junction box 100 includes a junction box body 101 , an upper cover 102 installed on the upper side of the junction box body 101 , and a lower cover 103 ins...
