Cable clamp for the electrical
A Cable clamp for the electrical embodying my invention includes a single elongated back plate provided with parallel cable-receiving grooves, a plurality of shorter front plates each of which is also provided with Cable clamp for the electrical-receiving grooves, and means such as a bolt acting between the back plate and each of the front plates to draw the two plates toward each other and clamp; the cable between them.
At or near the longitudinal center-line of the clamp, the back plate and each of the front plates are provided with alined holes for the reception of clamping means shown in the drawing as a bolt. In addition, each of the plates, both front and back, is provided with a pair of parallel lon- gitudinal grooves of arcuate cross-section adapted to receive a cable of the size with which the clamp is to be used.
The Cable clamp for the electrical constructed as described has a materially higher holding power than has a clamp consisting of a single pair of opposed plates, even though both clamps may embody as many clamping bolts and be of the same length. I believe this to be due to the fact that each of the individual front plates II is free to swing relatively to the back plate about the axis of its associated bolt except as limited by the presence of the cable within the plate-grooves.
3/16" to 5/16"
5/16" to 1/2"
A Cable clamp for the electrical of the type described, comprising an elongated back plate and a plurality of individual front plates, said back plate and each of said front plates being provided in their opposed faces with two laterally spaced, parallel, cable-receiving grooves extending longitudinally of the back plate, each of said front plates being rotatable relatively to said back plate about an axis perpendicular to the two plates and intermediate the two grooves in each, and clamping means acting between the back plate and each of the front plates for forcing them toward each other.
