Multipurpose boot for round-to-flat electrical cable

Details

Primary Examiner: Desmond; Eugene F.

A multipurpose boot for use with a jacketed round-to-flat multiconductor electrical cable comprises in one embodiment a sheet of adhesive coated flexible plastic material appropriately cut and scored to define a center panel, a pair of fold-over flaps and a tab. In use, the boot is placed about the cable and secured to the jacket with the end of the conductors lying on the tab. When the end of the cable is inserted into the connector for mass termination the tab is inserted along with it. When the connector is crimped closed the boot effectively connects the connector to the cable jacket so as to physically protect the cable in the area where it is neither flat nor round and to provide strain relief. In an alternate embodiment, the multipurpose boot is attached to the connector, but is not secured to the jacket. Instead, the boot is shaped to include guides for directing the conductors of the cable in a preselected orientation with respect to the connector.

DETAILED DESCRIPTION The present invention overcomes the problems set forth hereinabove by providing according to one embodiment of the invention a thin, low profile, flexible, multipurpose boot for incorporation with a round-to-flat multi-conductor electrical cable.
The boot has the capability of protecting the conductors against adverse external conditions while simultaneously providing relief from undesirable strain which may be placed on the conductors.
Several versions of this embodiment are disclosed.
In another embodiment of the present invention, the boot is configured so as to selectively position and neatly maintain the conductors, as a group, in any one of a number of predetermined different angular orientations with respect to the connector to which it is attached so as to accommodate a wide variety of uses to which the round-to-flat cable may be utilized.
Also, as will hereinafter become readily apparent, the invention can be utilized with all type of insulation displacement (IDC) type connectors.
More specifically, in the first embodiment of the present invention the boot is made of a single sheet of flexible plastic material such as PVC, polyester or polyurethane.
The sheet has a unique configuration which enables it to encompass the unjacketed and loosely bundled portion of the conductors and at the same time be fixedly secured to the connector to which the cable may be attached in a unique manner as well as to the jacket of the cable.
This configuration enables the plastic material to form a boot which acts not only as a means of protecting the conductors, but also because of its shape and method of assembly as a means of substantially eliminating undesirable strain which may be placed on the conductors in the transition area.
The strain relief is accomplished by inserting a tab integrally formed at one end of the boot directly into the connector along with the ends of the conductors of the round-to-flat cable and securing the other end of the boot to the (round) jacket of the cable with a suitable adhesive
