Patent ID: 7408110

Claim:
An electrical junction box for receiving an electrical component, comprising: (a) a generally rectangular hollow housing ( 1 ) having a pair of opposed parallel spaced vertical housing end walls ( 30 ) and a pair of opposed parallel spaced housing side walls ( 32 ) cooperating to partially define a chamber ( 34 ), one of said housing end walls containing at least one horizontal access passage ( 3 ) having a generally circular cross-sectional configuration, said housing being sectional and including upper( 102 ) and lower ( 2 ) sections defined by a horizontal plane passing through said access passage; and (b) a cylindrical sealing bush ( 6 ) mounted horizontally in and extending through said access passage, said bush being formed from a resilient electrically insulating synthetic plastic material and containing a longitudinal through bore ( 17 ), said bore having an inner circumferential wall surface upon which is mounted at least one integral annular elastically deformable sealing lip ( 20 ) having a given diameter, whereby when one end of an electrical conductor ( 15 ) having an outer diameter corresponding generally with said given diameter is inserted into said chamber via said through bore, said sealing lip will come into sealing engagement with the outer circumferential surface of the conductor, thereby to seal the housing chamber.
