Abstract
This disclosure depicts a novel cable clamp for use with a non-metallic electrical outlet box having rectangular apertures in the walls thereof and for securing a non-metallic sheathed electrical cable to the electrical outlet box. The cable clamp comprises a substantially U-shaped base which is slightly larger than the rectangular aperture in the wall of the electrical outlet box and first and second claw members attached on opposite sides of the base for securing the electrical cable after the cable clamp is positioned on the electrical cable and one of the claw members is inserted through the rectangular aperture in the wall of the electrical outlet box. The cable clamp securely holds the cable in position when either pushing or pulling tension is applied to the cable.
Claims6
A cable clamp for use with a non-metallic electrical outlet box having rectangular apertures in the walls thereof and for securing a non-metallic sheathed electrical cable to the electrical outlet box, said cable clamp comprising:
- a substantially U-shaped base which is slightly larger than the rectangular aperture in the wall of the electrical outlet box;
- and
- first and second claw members, each having a different size so that said cable clamp may be utilized with two different sized rectangular apertures in the non-metallic electrical outlet box and attached on opposite sides of said base for securing the electrical cable after said cable clamp is positioned on the electrical cable and one of said claw members is inserted through the rectangular aperture in the wall of the electrical outlet box;
- wherein said claw member which is inside of the electrical outlet box digs into the electrical cable when a tension attempting to pull the cable out of the electrical outlet box is applied to the cable and also wherein the claw member outside of the electrical outlet box digs into the cable when a tension is applied to the cable attempting to force the cable into the electrical outlet box, thereby said cable clamp securely holds the cable in position when either a pushing or pulling tension is applied to the cable.
A cable clamp for use with non-metallic electrical outlet boxes having rectangular apertures in the wall thereof and for securing a non-metallic sheathed electrical cable to the electrical outlet box, said cable clamp comprising:
- a substantially U-shaped base which is slightly larger than the rectangular aperture in the wall of the electrical outlet box;
- first and second claw members, each having a different size for use with different sized rectangular apertures in the non-metallic electrical outlet boxes and attached on opposite sides of said U-shaped base for securing the electrical cable, said first and second claw members each having first and second clamp sections;
- said first and second clamp sections being spaced a predetermined distance apart and each having,
- a positioning block which fits inside the rectangular aperture in the wall of the electrical outlet box,
- a flexible section having a first end attached to the inside edge of said positioning block,
- a cable retainer attached to a second end of said flexible section for contacting the electrical cable, and
- a holding portion having a first end attached to said second end of said flexible section and to said cable retainer, said holding portion also having a second end which contacts the wall of the electrical outlet box when said cable clamp is inserted in said rectangular aperture,
- wherein said claw member which is inside of the electrical outlet box digs into the electrical cable when a tension attempting to pull the cable out of the electrical outlet box is applied to the cable and also wherein the claw member outside of the electrical outlet box digs into the cable when a tension is applied to the cable attempting to force the cable into the electrical outlet box, thereby said cable clamp securely holds the cable in position when either a pushing or pulling tension is applied to the cable.
A non-metallic cable clamp for use with non-metallic electrical outlet boxes having rectangular apertures in the wall thereof and for securing a non-metallic sheathed electrical cable to the electrical outlet box, said cable clamp comprising:
- a substantially rectangular U-shaped base which is slightly larger than the rectangular aperture in the wall of the electrical outlet box;
- different size first and second claw members attached on opposite sides of said U-shaped base for securing the electrical cable, said first and second claw members each having first and second clamp sections;
- said first and second clamp sections being spaced a predetermined distance apart and each having,
- a positioning block which fits inside the rectangular aperture in the wall of the electrical outlet box, the height of said positioning block being substantially the same as the height of the aperture in the wall of the outlet box,
- a flexible section having a first end attached to the inside edge of said positioning block,
- a cable retainer attached to a second end of said flexible section for contacting the electrical cable, and
- a holding portion having a first end attached to said second end of said flexible section and to said cable retainer, said holding portion also having a second end which contacts the wall of the electrical outlet box when said cable clamp is inserted in said rectangular aperture,
- wherein said claw member which is inside of the electrical outlet box digs into the electrical cable when a tension attempting to pull the cable out of the electrical outlet box is applied to the cable and also wherein the claw member outside of the electrical outlet box digs into the cable when a tension is applied to the cable attempting to force the cable into the electrical outlet box, thereby said cable clamp securely holds the cable in position when either a pushing or pulling tension is applied to the cable.
