Abstract

A connector for electrical cords and cables includes a tubular body, a plastic engaging sleeve, a connecting sleeve, a connecting plug and a metal ring. The tubular body has a longitudinal through hole formed with a stepped recess at an end thereof, a first hole at an intermediate portion thereof, and a second hole at another end thereof. The plastic engaging sleeve has a stepped outer surface and formed with a conical longitudinal hole with a smaller inner diameter at the larger end thereof. The connecting sleeve has a tubular hexagonal nut portion from an end of which extends a cylindrical portion and is formed with a through hole having a recess at the outer end of the tubular hexagonal nut portion for receiving an O-ring, a circular rib adjacent to the recess and internal threads extending from the circular rib to an outer end of the cylindrical portion. The connecting plug has a longitudinal through hole for passage of an electrical cord or cable. The metal ring has a central hole for passage of an electrical cord or cable and fitted on the larger end of the plastic engaging sleeve for protecting the plastic engaging sleeve from damage.

Claims

1. A connector for electrical cords and cables comprising:

a tubular body having a longitudinal through hole formed with a stepped recess at an end thereof, a first hole at an intermediate portion thereof, and a second hole at another end thereof, said stepped recess being made up of two countersunk holes, said second hole being smaller than said first hole thereby forming a shoulder therebetween, said tubular member being formed with a plurality of grooves on an outer surface thereof;

a plastic engaging sleeve having a stepped outer surface and formed with a conical longitudinal hole with a smaller inner diameter at the larger end thereof, said plastic engaging sleeve having a circular groove at the intermediate portion and a circular projection adjacent to the circular groove which is configured to fit snugly into a circular groove of said tubular body;

a connecting sleeve having a tubular hexagonal nut portion from an end of which extends a cylindrical portion, said connecting sleeve being formed with a through hole having a recess at the outer end of the tubular hexagonal nut portion for receiving an O-ring, a circular rib adjacent to the recess and internal threads extending from said circular rib to an outer end of said cylindrical portion;

a connecting plug having a longitudinal rough hole for passage of an electrical cord or cable, an outer side of said connecting plug being formed with a stepped conical portion at one end and a flange at another end, said stepped conical portion being configured to engage tightly with said tubular body thereby strengthening positioning of said electrical cord or cable, said flange bearing against said circular rib when said connecting plug is pushed into said connecting sleeve; and

a metal ring having a central hole for passage of an electrical cord or cable and fitted on the larger end of said plastic engaging sleeve for protecting said plastic engaging sleeve from damage.
