Electrical connector with removable spacer
An electrical connector for receipt of EMT or rigid conduit has a body with first and second body portions, the first portion having a hollow interior with an inner smooth cylindrical surface having a radius of curvature dimensioned for receipt of a rigid electrical conduit, a removable spacer having an inner smooth surface with a radius of curvature substantially corresponding to a radius of curvature of an outer surface of an EMT, the removable spacer also having an outer surface corresponding to the inner smooth cylindrical surface of the first body portion, and wherein the second body portion forms a stop adjacent the second end of the first body portion so as to contact a terminating end of a rigid conduit or EMT. The second body portion has a central bore for the passage of electrical conductors.
1. An electrical connector for receipt of an electrical metallic tubing (EMT) or a rigid electrical conduit, comprising:
a body formed from an electrically conductive material, the body having a first body portion and a second body portion,
the first body portion having a first end and a second end, and a hollow interior extending from the first end to the second end with an inner smooth cylindrical surface having a radius of curvature dimensioned for receipt of a rigid electrical conduit, and a threaded hole extending through the first body portion to the hollow interior, the threaded hole dimensioned for receipt of a screw so as to secure a rigid electrical conduit or an electrical metallic tubing (EMT) received in said hollow interior;
a removable spacer fabricated from metal, the removable spacer having a shape that is a section of a cylinder, the removable spacer having an inner smooth surface with a radius of curvature substantially corresponding to a radius of curvature of an outer surface of the EMT, the removable spacer also having an outer smooth surface having a radius of curvature substantially corresponding to the radius of curvature of the inner smooth cylindrical surface of the first body portion so that the removable spacer makes secure contact with the outer surface of the EMT; and
wherein the second body portion of the body is integrally formed at the second end of the first body portion, the second body portion having an internal ridge that forms a stop adjacent the second end of the first body portion, the stop dimensioned to contact a terminating end of the rigid electrical conduit or the EMT received in the first body portion, the second body portion having a central bore for the passage of electrical conductors associated with the rigid electrical conduit or the EMT secured to the first body portion, and also having a threaded outer surface for receipt of a locknut.
2. The electrical connector according to claim 1 , wherein the removable spacer includes a post extending from the outer surface of the removable spacer, the post dimensioned for insertion into an aperture formed in the inner smooth cylindrical surface of the first body portion.
3. The electrical connector according to claim 2 , wherein the aperture passes through the first body portion.
4. The electrical connector according to claim 3 , wherein the removable spacer further includes a slot formed therein dimensioned for insertion of a tool between the removable spacer and the inner smooth cylindrical surface of the first body portion so as to assist in removal of the spacer from the body.
5. The electrical connector according to claim 1 , wherein the removable spacer further includes a slot formed therein dimensioned for insertion of a tool between the removable spacer and the inner smooth cylindrical surface of the first body portion so as to assist in removal of the spacer from the body.
6. The electrical connector according to claim 1 , wherein the removable spacer metal is zinc alloy.
7. The electrical connector according to claim 1 , wherein the body is zinc die cast.
