Abstract
An apparatus is provided that electrically insulates an elongate body from a rigid member. The apparatus includes an insulating part and a helically shaped securing part. The insulating part contacts either the elongate body or the rigid member thereby electrically insulating the elongate body from the rigid member. The helically shaped securing part prevents the insulating part from moving. The helically shaped securing part includes a multiple continuous rods, whereby the multiple rods are individual rods or sets of rods where at least two of the continuous rods are adhered together with an adhesive to form a set.
Claims24
An apparatus that electrically insulates an elongate body from a rigid member comprising:
- an insulating part that contacts either the elongate body or the rigid member thereby electrically insulating the elongate body from the rigid member;
- and
- a helically shaped securing part that prevents the insulating part from moving or becoming dislodged, the helically shaped securing part comprises a helically shaped first leg;
- a helically shaped second leg;
- and
- a substantially U-shaped part connecting the helically shaped first leg and the helically shaped second leg such that the helically shaped first leg, the helically shape second leg and the U-shaped part are continuous,
- wherein the helically shaped first leg and the helically shaped second leg are configured to wrap around the elongate body in an alternating arrangement;
- and
- wherein the insulating part includes an insulating material disposed between a bight part of the U-shaped part and the rigid member.
An apparatus that insulates an elongate body from a rigid member comprising:
- a helically shaped first leg;
- a helically shaped second leg;
- and
- a substantially U-shaped part connecting the helically shaped first leg and the helically shaped second leg such that the helically shaped first leg, the helically shaped second leg and the U-shaped part are continuous, the U-shaped part including a bight part and being encompassed by an insulating material disposed between the bight part and the rigid member, wherein the insulating material electrically insulates the elongate member from the rigid member, wherein the helically shaped first leg, the helically shaped second leg, and the U-shaped part are formed from a plurality of continuous rods.
A method of insulating an elongate member from a rigid member comprising:
- applying an insulating part to the elongate member;
- applying a casing around the insulating part;
- and
- securing the casing and insulating part the rigid member with a fastening device, wherein the fastening device includes:
- a helically shaped first leg;
- a helically shaped second leg;
- and
- a substantially U-shaped part connecting the helically shaped first leg and the helically shaped second leg such that the helically shaped first leg, the helically shaped second leg and the U-shaped part are continuous,
- wherein the helically shaped first leg and the helically shaped second leg are configured to wrap around the elongate body in an alternating arrangement;
- and
- wherein the insulating part includes an insulating material disposed between a bight part of the U-shaped part and the rigid member.
