Problems solved by technology

[0007] However, in the attachment structure of the conventional electrical junction box as disclosed in Patent Document 1, there is a problem that it is difficult to provide a large gap between the outer peripheral surface of the electrical junction box and the opening peripheral portion of the attachment hole.
This will cause a problem that the strength of the flange portion itself and the fixing strength of the flange portion when it is fixed to the vehicle body panel are greatly reduced.
[0008] Furthermore, in the attachment structure of the electrical junction box disclosed in Patent Document 1, when the electrical junction box is detached from the vehicle body panel after installation, there is a problem that it is difficult to release the engaging claws from the rear side surface of the vehicle body panel.
This will lead to a problem that the mold for the electrical junction box becomes complicated, and since a tool must be inserted into a small hole to release the engagement claw, the release work is troublesome

Embodiment Construction

[0022] Referring now to the drawings, an embodiment of an electrical junction box according to an exemplary preferred embodiment will be described in detail below to clarify aspects of the preferred embodiment.

[0023] Figure 1 to Figure 3 One embodiment of a connector holder 10 is shown, which is an example of an electrical junction box according to an exemplary preferred embodiment. The connector holder 10 is a molded product made of a material such as synthetic resin. The connector holder 10 includes a main body 12 serving as a main body of an electrical junction box. The main body 12 is basically formed on both upper and lower sides ( image 3 A rectangular box-shaped structure with openings on the upper and lower sides of the middle. This main body 12 constitutes a connector accommodating portion. Such as figure 2 As shown, the connector 13 can be received and secured in the body 12 in an engaging or fitting manner using a rod.

[0024] The connector holder 10 ca...

Abstract

The invention provides an electrical junction box having a new structure that can be securely attached to a hole and can be readily removed even if a large clearance is required between the electrical junction box and a peripheral edge section around the attachment hole. An elastic projecting piece is integrally provided on a main body of an electrical junction box. The elastic projecting piece protrudes from an outer surface of the main body. The elastic projecting piece is provided with an engagement projection and an attachment projection that protrude outward from the main body opposite from each other in an extending direction of the elastic projecting piece to constitute an engagement fixing section. Elastic deformation of the elastic projecting piece permits the main body to be fitted into the attachment hole. A second inner peripheral edge portion around the attachment hole is clamped between the engagement and attachment projections.

Description

[0001] cross reference [0002] This application claims priority from JP 2009-156377 filed in Japan on Jun. 30, 2009, the disclosure of which is hereby incorporated by reference. technical field [0003] According to an aspect of an exemplary embodiment, the embodiment relates to an electric junction box mounted on a motor vehicle or the like, and more particularly, to an electric junction box fitted into an attachment hole of a vehicle body panel to be mounted on the vehicle body. Background technique [0004] Electrical equipment in motor vehicles is usually housed in boxes, for example in fuse boxes, junction boxes or connector holders. Electrical junction boxes are typically attached to body panels in the vehicle compartment or engine compartment. There is an electric junction box in which, when the electric junction box is mounted on a vehicle body panel, the amount of protrusion into a vehicle compartment or the like is reduced only by fitting the electric junction bo...
