Abstract

The present disclosure relates to and envisages an electrical junction box assembly. The electrical junction box assembly (10) comprises a housing (100) having lateral openings (120) and a lid (130). In one aspect, the housing (100) has mounting feet (140) with at least one of them having a slit (144). In another aspect, the base (110) has bosses (150) for fixing a terminal block (200). In yet another aspect, the housing (100) is provided with an external drainage protrusion (160) configured to be sheared off to provide a drainage hole. In still another aspect, the lid (130) is captively joined to the rest of said housing (100).

First claim

We claim:

1 . An electrical junction box assembly ( 10 ) comprising:
a housing ( 100 ) having:
a space for containing an electrical terminal block ( 200 ):
a lateral surface surrounding said space;
an operative top opening for placement and removal of the terminal block ( 200 );
a plurality of lateral openings ( 120 ) on said lateral surface for allowing insertion of electrical wires to be connected to said terminal block ( 200 );
a base ( 110 ) providing a closed end to said lateral surface, wherein said base ( 110 ) is for fixing said terminal block ( 200 ); and
a removable and detachable lid ( 130 ) for covering said operative top opening of said housing ( 100 ); characterized in that said housing ( 100 ) has at least one pair of mounting feet ( 140 ), each mounting foot of said pair of mounting feet ( 140 ) extending from the periphery of said base ( 110 ) external to said housing ( 100 ), a first mounting foot of said pair of mounting feet ( 140 ) having an aperture ( 142 ), and a second mounting foot of said pair of mounting feet ( 140 ) having a slit ( 144 ), said aperture ( 142 ) configured to receive a first fastener for precise placement on a surface of a fastener therein, and said slit ( 144 ) configured to receive a second fastener therethrough for fixing said junction box assembly ( 10 ), wherein said mounting feet ( 140 ) of said pair of mounting feet ( 140 ) are located on diagonally opposite positions of said base ( 110 ) of said housing ( 100 ); and wherein said lateral surface of said housing ( 100 ) is provided with a drainage protrusion ( 160 ) in an unsheared state, said drainage protrusion ( 160 ) is configured to be sheared, wherein a drainage hole is provided after shearing said drain protrusion ( 160 ) such that said drain protrusion ( 160 ) is in a sheared state, for facilitating drainage of fluid within said space of said housing ( 100 ).

2 . The junction box assembly ( 10 ) as claimed in claim 1 , wherein said drainage protrusion ( 160 ) has a circular cross-section provided with a first center, wherein at least one of said plurality of lateral openings ( 120 ) also has a circular cross-section with a second center, wherein said first center and said second center are provided along a plane.

3 . The junction box assembly ( 10 ) as claimed in claim 1 , wherein said drainage protrusion ( 160 ) is diametrically opposite of at least one of said plurality of lateral openings ( 120 ).

4 . The junction box assembly ( 10 ) as claimed in claim 1 , wherein said first mounting foot of said pair of mounting feet ( 140 ) and said second mounting foot of said pair of mounting feet ( 140 ) are integrally formed with said base ( 110 ).

5 . An electrical junction box assembly ( 10 ) comprising:
a housing ( 100 ) having:
a space for containing an electrical terminal block ( 200 );
a lateral surface surrounding said space;
an operative top opening for placement and removal of said terminal block ( 200 );
a plurality of lateral openings ( 120 ) on said lateral surface for allowing insertion of electrical wires to be connected to said terminal block ( 200 );
a base ( 110 ) for fixing said terminal block ( 200 ); and
a removable and detachable lid ( 130 ) for covering said operative top opening of said housing ( 100 ); characterized in that said lateral surface of said housing ( 100 ) is provided with a drainage protrusion ( 160 ) having an entirely closed end in an unsheared state, said drainage protrusion ( 160 ) configured to be sheared, wherein a drainage hole is provided after shearing said drain protrusion ( 160 ) such that said drain protrusion ( 160 ) is in a sheared state, for facilitating drainage of accumulated fluid within said space of said housing ( 100 ).

6 . The junction box assembly ( 10 ) as claimed in claim 5 , wherein said drainage protrusion ( 160 ) has a thickness less than a radial width of said protrusion, thereby defining a concave operative inner profile ( 162 ) of said drainage protrusion ( 160 ).

7 . The junction box assembly ( 10 ) as claimed in claim 6 , wherein maximum thickness along said concave operative inner profile ( 162 ) of said drainage protrusion ( 160 ) is equal to the thickness of said lateral surface of said housing ( 100 ).

8 . The junction box assembly ( 10 ) as claimed in claim 5 , wherein said drainage protrusion ( 160 ) is configured to be sheared off by drilling or tapping.

9 . The junction box assembly ( 10 ) as claimed in claim 5 , wherein said junction box assembly ( 10 ) includes a drainage valve ( 164 ) configured to be fitted on said drainage hole obtained by shearing off said drainage protrusion ( 160 ) by drilling or tapping.
