Abstract

A strain relief clamp suitable for protecting power cables, fuel lines, wire harnesses, and the like, which includes first and second identical metallic clamp members. Each of the first and second clamp members includes first and second ends and a right angle bend which forms first and second leg portions which respectively extend from the first and second ends to the bend. The first leg portions are corrugated to define curved recesses which cooperatively define elongated apertures when the first leg portions are fixed in assembled relation via aligned openings defined by the first leg portions. The second leg portions include openings adapted to fix the assembled first and second clamp portions to a housing associated with the items to be protected.

Claims

1. A strain relief clamp comprising:

first and second identical metallic clamp members,

said first and second clamp members each having first and second ends, and a bend intermediate said ends which defines first and second right angle leg portions which respectively extend from said bend to said first and second ends,

the first leg portion of each of said first and second clamp members being corrugated to define a plurality of uniformly spaced, integrally joined, curved recesses separated by flat portions,

and means for fixing said first and second clamp members in assembled relation wherein the spaced curved recesses of the first leg members of the assembly cooperatively define a plurality of elongated open-ended apertures,

said means for fixing the first and second clamp members in assembled relation including openings defined by the first leg portions located in said flat portions between the spaced curved recesses, and fastener means disposed to link adjacent openings in the first and second clamp members,

said second leg portions of the first and second clamp members each defining openings adapted to fix one of the first and second clamp members of the assembly to an associated structure,

said bend which joins the first and second right angle leg portions being a radiused bend which defines a circular arc having a radius of at least about .75 inch to enable each of said first and second clamp members to be formed by a single break and form operation,

said curved recesses extending in parallel relation from the first end of said first leg portion, through said radiused bend, and partially into said second leg portion.

2. The strain relief clamp of claim 1 wherein the first and second clamp members are formed of stainless steel.
