Abstract
An insulating tubular connector is formed of layers of heat shrinkable plastic with the inner layer having a plurality of inwardly extending retention tabs for physically engaging wires or the like over which the tube is fitted to mechanically retain said tube on the wires until permanent bonding can be effected by heat shrinkage of the tube of the connector.
Claims10
An insulating connector comprising:
- a. a heat shrinkable tube comprising a spiral laminate formed of plural ribbons of heat recoverable plastic material, said tube having an inner surface;
- and
- b. said tube including a plurality of tab members formed of portions of said spiral laminate bent inwardly from remaining portions of said spiral laminate and extending unitarily inwardly from said inner surface of said tube for physically engaging wires or the like over which said tube can be fitted to mechanically retain said tube thereon until permanent retention thereon can be effected by subsequent heat shrinkage of said tube over such wires or the like.
An insulating connector comprising:
- a. a heat shrinkable tube comprising a spiral laminate formed of a plurality of plastic ribbons formed of heat recoverable material, said tube having an inner surface and a cylindrical shape;
- and
- b. said tube including a plurality of tab members formed of portions of said spiral laminate bent inwardly from remaining portions of said spiral laminate and extending unitarily inwardly from said inner surface of said tube for physically engaging wires or the like over which said tube can be fitted to mechanically retain said tube thereon until permanent retention thereon can be effected by subsequent heat shrinkage of said tube over which such wires or the like.
An insulating connector comprising:
- a. a heat shrinkable tube comprising a spiral laminate formed of heat recoverable plastic material, said tube having an inner surface;
- and
- b. said tube including a plurality of tab members having a pointed inner end, said tab members being formed of portions of said spiral laminate bent inwardly from remaining portions of said spiral laminate and extending unitarily inwardly from said inner surface of said tube for physically engaging wires or the like over which said tube can be fitted to mechanically retain said tube thereon until permanent retention thereon can be effected by subsequent heat shrinkage of said tube over such wires or the like.
An insulating connector comprising:
- a. a heat shrinkable tube comprising a spiral laminate formed of heat recoverable plastic material, said tube having an inner surface;
- and
- b. said tube including a plurality of tab members having a curved inner end, said tab members being formed of portions of said spiral laminate bent inwardly from remaining portions of said spiral laminate and extending unitarily inwardly from said inner surface of said tube for physically engaging wires or the like over which said tube can be fitted to mechanically retain said tube thereon until permanent retention thereon can be effected by subsequent heat shrinkage of said tube over such wires or the like.
An insulating connector comprising:
- A. a tube formed of heat-shrinkable material and comprising a spiral laminate formed of a plurality of plastic ribbons, one end of said tube being closed;
- and
- B. said tube including a plurality of tab members formed of a portion of said spiral laminate bent inwardly from remaining portions of said spiral laminate for physically engaging wires or the like over which said tube can be fitted to mechanically retain said tube thereon until permanent retention over such wires or the like.
