Abstract

Abstract A reusable cap encapsulates an electrical terminal in a junction box which routes communication lines such as phone wires. The cap includes a tubular body having a self tearing slot which receives a phone wire radially extending from a stud of a terminal. The cap also has an indicator knob having a pointed end which is angularly aligned with said self tearing slot. A technician can insert the cap over the terminal by aligning the indicator end of the knob with the phone wire, thereby aligning the self tearing slot with the wire. As the cap is inserted over the terminal, the wire penetrates and splits the self tearing slot. The cap is filled with a water impermeable elastic electrical insulating semi solid gel which encapsulates the terminal upon insertion of the cap. When the cap is removed, the gel is retained in the cap and cleanly pulls away from the terminal. A color coded indicator tab may be inserted onto the knob of the cap for indicating secured status of the phone wire.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 174 words
A cap for encapsulating a terminal having a substrate with an extending stud suitably adapted to receive a wire thereon comprising: a tubular body having a distal end and a proximal end, said proximal end sized to surround said terminal; a water impermeable gel disposed within said tubular body, said gel being semi-solid and elastic through ambient temperatures for conforming about said stud upon insertion of said cap onto said terminal; self-tearing slot means for receiving said wire radially extending from said stud, said slot means extending from said proximal end of said tubular body toward said distal end of said tubular body; said slot means comprising a reduced thickness web portion upon said tubular body adapted to be torn by said wire upon insertion of said cap upon said terminal; indicator means formed on said distal end of said tubular body for indicating the position of said slot means; and a tab adapted to be removably attached to said indicator means to indicate the secure status of said wire associated with said terminal.
Claim 2
Dependent Claim 174 words
A cap for encapsulating a terminal having a substrate with an extending stud suitably adapted to receive a wire thereon comprising: a tubular body having a distal end and a proximal end, said proximal end sized to surround said terminal; a water impermeable gel disposed within said tubular body, said gel being semi-solid and elastic through ambient temperatures for conforming about said stud upon insertion of said cap onto said terminal; self-tearing slot means for receiving said wire radially extending from said stud, said slot means extending from said proximal end of said tubular body toward said distal end of said tubular body; said slot means comprising a reduced thickness web portion upon said tubular body adapted to be torn by said wire upon insertion of said cap upon said terminal; indicator means formed on said distal end of said tubular body for indicating the position of said slot means; and a tab adapted to be removably attached to said indicator means to indicate the secure status of said wire associated with said terminal.
Claim 3
Dependent Claim 26 words
The cap of claim 1 further comprising a flange formed adjacent said proximal end of said tubular body, said flange formed to rigidify said tubular body.
Claim 4
Dependent Claim 23 words
The cap of claim 1 wherein said tab is color coded to indicate the secure status of said wire associated with said terminal.
Claim 5
Dependent Claim 25 words
The cap of claim 1 further comprising a plurality of struts disposed within said tubular body and sized to engage a portion of said terminal.
Claim 6
Dependent Claim 25 words
The cap of claim 1 wherein said plurality of struts are formed having a wear resistant surface for engagement with a portion of said terminal.
Claim 7
Dependent Claim 161 words
A cap for encapsulating terminals having a boss with an extending stud for interconnecting said terminal with a wire, comprising: a tubular body having a distal end and a proximal end, said proximal end sized to cover said terminal; self-tearing slot means for receiving said wire in said tubular body permitting said wire to be radially extended from said extending stud; knob means connected to said tubular body at said distal end, said knob means having a pointer reference thereon for indicating the location of said self-tearing slot with said wire; a color coded tab suitably shaped for attachment to said knob means for indicating the status of said wire; said knob means including a pointed end, said knob means also including a recess, said recess having a corresponding pointed end and an aperture extending therethrough; and said color coded tab is shaped complimentary to said recess and includes a pin, said pin insertable through said aperture of said knob means.
Claim 8
Dependent Claim 161 words
A cap for encapsulating terminals having a boss with an extending stud for interconnecting said terminal with a wire, comprising: a tubular body having a distal end and a proximal end, said proximal end sized to cover said terminal; self-tearing slot means for receiving said wire in said tubular body permitting said wire to be radially extended from said extending stud; knob means connected to said tubular body at said distal end, said knob means having a pointer reference thereon for indicating the location of said self-tearing slot with said wire; a color coded tab suitably shaped for attachment to said knob means for indicating the status of said wire; said knob means including a pointed end, said knob means also including a recess, said recess having a corresponding pointed end and an aperture extending therethrough; and said color coded tab is shaped complimentary to said recess and includes a pin, said pin insertable through said aperture of said knob means.
Claim 9
Dependent Claim 58 words
The cap of claim 6 wherein said tubular body further comprises a neck portion disposed between said proximal end and said knob means, said neck portion having a plurality of struts within a cavity of said tubular body for supporting said neck portion, said struts having a wear resistant surface for engagement of threads of said terminal stud.
