Abstract

A cable anchor assembly for facilitating ready anchored connection of cables to components while protecting the cables from external forces and from moisture. The assembly includes a plurality of plates slidably engageable along a rail for facilitating relative movement between the plates. Each plate has an engaging edge that defines a portion of a formable collar in which a cable is receivable. A fixture, such as a rubber boot, is placed over a section of the cable and, with the plates separated, the cable section is placed between the formable collar portions, whereupon the plates are brought into sliding edge-to-edge contact with each other to enclose the cable section and boot. With the plates in contact, a securing mechanism is operated to maintain contact between the plates. In a preferred embodiment, the boot is configured to create a substantially water-resistant seal between the cable section and the movable plates.

Claims

1. A cable anchor assembly, comprising:

a first plate having a securing edge and an engaging edge, said engaging edge defining a portion of a formable collar;

a second plate having a securing edge and an engaging edge, said second plate engaging edge defining a remainder of the formable collar;

a first rail capable of receiving said securing edges of said first and second plates for accommodating slidable relative movement of said plates with respect to each other, said plates being mounted to said first rail so that said engaging edges of said first and second plates form the formable collar and the formable collar defines an opening through the cable anchor assembly when said plates are slid into contact with each other to accommodate placement of a cable between said collar portion and said remainder portion and extending through said opening; and

means for releasably securing said first and second plates together to retain a cable within said formable collar and extending through said opening, said securing means comprising a groove formed on a surface of each of said first plate and said second plate, a member pivotally connected at one end to one of a fixed surface and said first rail and dimensioned for seating within said groove, and a tightening clip for releasably fastening to a second end of said member.

2. The assembly of claim 1, wherein each of said first and second plates includes a second securing edge opposite said first securing edge of said each plate, said assembly further comprising a second rail spaced from said first rail for receiving, for slidable relative movement, said second securing edges of said first and second plates so that said plates are slidable along and between said first and second rails.

3. The assembly of claim 1, wherein one of said first and second plates has a surface in which a fixed collar opening is defined through said one plate, said fixed collar opening being surrounded by a fixed collar for accommodating passage of a cable through said fixed collar and said fixed collar opening.

4. The assembly of claim 3, wherein said formable collar and said fixed collar each have an inner surface defining a protrusion for engaging a cable positioned through each said collar.

5. The assembly of claim 1, wherein said formable collar has an inner surface defining a protrusion for engaging a cable placed between said formable collar portion and remainder portion and extending through said opening when said first and second plates are secured together.

6. A cable anchor assembly, comprising:

a first plate having a securing edge and an engaging edge, said engaging edge defining a portion of a formable collar;

a second plate having a securing edge and an engaging edge, said second plate engaging edge defining a remainder of the formable collar;

a flexible boot having a longitudinal axis and configured for placement along said longitudinal axis about a cable to be anchored by said assembly, said boot having a first tapered portion, a second tapered portion and a center portion, said first and second tapered portions each having a wide end and a narrow end and oriented relative to said longitudinal axis so that said wide ends are connected to said center portion;

a first rail configured for receiving said securing edges of said first and second plates for accommodating slidable relative movement of said plates with respect to each other, said plates being mounted to said first rail so that said engaging edges of the first and second plates form the formable collar and the formable collar defines an opening through the cable anchor assembly when said plates are slid into contact with each other to accommodate placement of the cable with said boot placed thereon between said collar portion and said remainder portion with the cable extending through said opening so that said boot interfaces the cable with said formable collar; and

means for releasably securing said first and second plates together to retain the cable and said boot within said formable collar with the cable extending through said opening.

7. The assembly of claim 6, wherein each of said first and second plates includes a second securing edge opposite said first securing edge of said each plate, said assembly further comprising a second rail spaced from said first rail for receiving, for slidable relative movement, said second securing edges of said first and second plates so that said plates are slidable along and between said first and second rails.

8. The assembly of claim 6, wherein said formable collar has an inner surface defining a protrusion for engaging said boot and the cable placed between said formable collar portion and remainder collar portion when said first and second plates are secured together.

9. The assembly of claim 6, wherein said boot is constructed of a substantially water-resistant material.

10. The assembly of claim 6, wherein said formable collar has an upper surface and wherein said boot further comprises an upper radially protruding ridge disposed between said center portion and said first tapered portion, said upper ridge being seated on said formable collar upper surface when a cable is secured within said formable collar so that said upper ridge seats on said upper surface of said formable collar.

11. The assembly of claim 10, wherein said formable collar has a lower surface and wherein said boot further comprises a lower radially protruding ridge disposed between said center portion and said second tapered portion, said lower ridge being seated on said formable collar lower surface when a cable is secured within said formable collar so that said lower ridge seats on said lower surface of said formable collar.
