Abstract
This open sleeve support is consisting of a central flat or slightly curved part (1), preferably of constant thickness, provided with two lateral branches (2) growing more narrow downwards, the latter being connected through a small fillet, to the two flat and parallel flanges (4) bent inwards and almost reaching the center of the sleeve, so that the support can be easily fitted on cables of various size (7) by slipping the sleeve on laterally, without risk of failure, while remaining firmly in place.
Claims12
An open sleeve identification device for electrical cables, which comprises:
- (a) a central body portion having opposed side edges;
- (b) a pair of opposed leg portions extending from said side edges and terminating in distal ends thereof, said leg portions being tapered towards said distal ends;
- and
- (c) a pair of resilient flange portions, each connected at one end thereof to a said distal end of said leg portions by a close bend fillet and terminating in a free end thereof at approximately the mid-point of the leg portion, said flange portions having a normal position in which they are parallel,
- (d) said resilient flange portions being operable to be urged apart from said normal position to a more widely spaced apart position when a cable of a first size is forced therebetween toward said central body portion and to return to said normal position when said first size cable contacts said body portion, whereby said first size cable contacts and is secured between said free ends of said flange portions and said central body portion;
- and
- (e) said resilient flange portions being further operable to be urged apart from said normal position to a more widely spaced apart position when a cable of a larger size than said first size is forced therebetween toward said central body portion and to remain in a said more widely spaced position when said larger size cable contacts said body portion, whereby said larger size cable is gripped by said flange portions and contacts said central body portion.
