Electric junction box
View Patent ↗There is provided an electric junction box for ensuring a watertight performance even when a harness with various thickness is applied, including a box body, a tubular guide portion projecting from the box body and guiding a harness out of the box body, wherein the guide portion is provided with a plurality of wall portions, divided along the axial direction of the guide portion, and at least one of the wall portions is provided with a movable spurtle as a spurtle and a bending portion formed between the movable spurtle and the box body elastically deformable in the outside direction of the guide portion, and wherein the inner diameter of the guide portion in neutral state that the bending portion is not in elastic deformation is formed to fit the harness with a minimum outer diameter.
1. An electric junction box comprising:
a box body;
a tubular guide portion projecting from the box body and guiding a harness out of the box body;
a plurality of wall portions provided with the guide portion and divided along an axial direction of the guide portion; and
a spurtle and a bending portion provided with at least one of the plurality of wall portions, the bending portion being formed between the spurtle and the box body elastically deformable in the outside direction of the guide portion,
wherein the inner diameter of the guide portion in neutral state that the bending portion is not in elastic deformation is formed to fit the harness with a minimum outer diameter, and
wherein the bending portion is bent so that the spurtle is directed outward with the increase of the diameter of the harness.
2. The electric junction box as claimed in claim 1 ,
wherein the spurtle includes a stand portion standing from the spurtle and stacked on the inner surface of the adjoining wall portion.
3. The electric junction box as claimed in claim 1 or 2 ,
wherein the guide portion includes a rib formed convexly in the outside direction of the spurtle for preventing a fixing member wound continuously from the guide portion to the harness with the harness through the inside of the spurtle from being dislocated, and wherein the rib is spaced from an end portion of the guide portion away from the box body.
