Abstract
A ground clamp having upper and lower clamp members interconnected by clamping screws for mechanical and electrical connection with a grounding member, and a frontally projecting boss on the lower clamp member having a downwardly opening slot for receiving a ground wire which is retained by a set screw forward of the clamping screws whereby the various screws may be independently tightened without interference from adjacent screws.
Claims4
A ground clamp for electrically connecting a ground wire to a parallel grounding member, said ground clamp comprising:
- an upper clamp member having an upper center section and outwardly extending upper end sections;
- a downwardly opening transverse upper groove on said upper center section having laterally opposed surfaces for engaging an upper surface of the grounding member;
- a lower clamp member a lower center section and outwardly extending lower end sections underlying said upper end sections of said upper clamp member;
- an upwardly opening transverse lower groove on said lower center section having laterally opposed surfaces for contacting a lower surface of the grounding member;
- a threaded hole in each of said lower end sections of said lower clamping member;
- a through hole in one of said upper end sections axially registering with one of said threaded holes in said lower clamping member;
- a transversely opening slot in the other of said upper end sections axially registering with the other of said threaded holes in said lower clamp member;
- a first clamping screw having a threaded shank extending through said hole in said one of said upper end sections and one of said threaded holes, and having a slotted head engaging a top surface of said one of said upper end sections;
- a second clamping screw having a threaded shank extending through said slot in said other of said upper end sections and the other of said threaded holes, and having a slotted head engaging a top surface of said other of said upper end sections;
- a boss formed integrally with said center section of said lower clamp member below said lower groove, said boss having laterally spaced side walls forming a downwardly opening slot;
- a recessed section formed on an inner surface of one of said side walls whereby the ground wire may be inserted through said downwardly opening slot and against said recessed section;
- a laterally threaded hole formed in the other of said side walls;
- a set screw received in said laterally threaded hole having an end portion for engaging the ground wire and clamping the ground wire against said recessed section.
A ground clamp for electrically connecting a ground wire to a parallel grounding member, said ground clamp comprising:
- an upper clamp member and a lower clamp member having opposed transversely grooved surfaces for contacting the grounding member;
- a pair of laterally spaced threaded clamping screws interconnecting opposed lateral end portions of said clamp members and disposed in a first vertical plane;
- a boss formed integrally with said lower clamp member below said grooved surface therein and projecting forwardly thereof;
- a downwardly opening slot formed in said boss for receiving the ground wire;
- a set screw transversely formed in said boss and intersecting said slot, said set screw disposed in a second vertical plane space sufficiently forward of said first vertical plane whereby said screws may be independently operated without interference from adjacent screws.
