Abstract

An object of the present invention is to provide an electrical junction box having a new structure that can restrain noises from leaking through a support member and can advantageously secure a fixing strength onto the support member in the electrical junction box fixed on a support member by inserting an arm section projecting from a box main body into an attaching aperture in the support member. An arm section is loosely inserted into a support member. The arm section is provided on its extending distal end with an engaging portion that is pushed through an attaching aperture in the support member into an interior of the support member to be engaged with a rear surface of the support member. The arm section is integrally provided with a first wall portion opposed through the support member to the engaging portion. The first wall portion covers the attaching aperture.

Claims

1. An electrical junction box comprising:

an arm section projecting from a box main body that is loosely inserted into an attaching aperture in a support member, wherein said arm section is engaged with said support member, and said box main body is fixed on said support member,

said arm section is provided on a projecting distal end with an engaging portion that is inserted through said attaching aperture into an interior of said support member to be engaged with a rear surface of said support member,

said arm section is integrally provided with a first wall portion that is opposed through said support member to said engaging portion, and

said first wall portion is adapted to cover said attaching aperture.

2. An electrical junction box according to claim 1, wherein an insulator is adhered to a surface of said support member, said insulator is provided with a communication aperture that is communicated with said attaching aperture, and said arm section is integrally provided with a second wall portion for covering said communication aperture.

3. An electrical junction box according to claim 1, wherein said first wall portion is elastically deformable in a pushing direction onto said support member, and said engaging portion is pressed onto a rear surface of said support member by resilience of said first wall portion.

4. An electrical junction box according to claim 1, wherein said arm section is provided on said projecting distal end with a tapered sharp portion in a projecting direction of said arm section.

5. An electrical junction box according to claim 2, wherein said first wall portion is elastically deformable in a pushing direction onto said support member, and said engaging portion is pressed onto a rear surface of said support member by resilience of said first wall portion.

6. An electrical junction box according to claim 2, wherein said arm section is provided on said projecting distal end with a tapered sharp portion in a projecting direction of said arm section.

7. An electrical junction box according to claim 3, wherein said arm section is provided on said projecting distal end with a tapered sharp portion in a projecting direction of said arm section.
