Abstract
Abstract A connector assembly for electrically connecting a first wire to a second insulation clad wire. A connector assembly generally comprises a unitary terminal including a relatively rigid portion having a wire trap means for receiving a conductive part of the first wire and a wire piercing side with a first insulation cutting edge formed thereon. The terminal also includes a resilient portion spaced from the wire piercing side having a second insulation cutting edge thereon facing the first cutting edge. The space between the first and second cutting edges defines an insulation displacement slot for receiving the second wire. The cutting edges are spaced a distance not less than the diameter of the conductive part of the first wire. The assembly also comprises a housing with an opening through which the terminal is receivable. The housing generally includes a first compartment for receiving the rigid portion of the terminal and the first wire. The housing also includes a second compartment spaced from the first compartment for receiving the resilient portion of the terminal. A wire loading slot is defined between the first and second compartments for receiving the second wire prior to engagement with the terminal. The compartments have means allowing communication with the loading slot. The second compartment has a cam surface formed thereon for engagement with the resilient portion for moving the second cutting edge toward the first cutting edge as the terminal is inserted into the housing. In this manner the cutting edge displaces the insulation of the second wire at the loading slot and engages the conductive part thereof.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
251 words
A connector assembly for electrically connecting a first wire to a second insulation clad wire comprising: a unitary terminal including a relatively rigid portion having a wire trap means for receiving a conductive part of the first wire and a wire piercing side with a first insulation cutting edge formed thereon, said terminal further including a resilient portion spaced from said wire piercing side having a second insulation cutting edge formed thereon facing and movable toward said first cutting edge, the space between said first and second cutting edges defining an insulation displacement slot for receiving said second wire and being spaced a distance not less than the diameter of the conductive part of said first wire; and a housing with an opening through which said terminal is receivable, said housing including a first compartment for receiving the rigid portion of the terminal and said first wire, a second compartment spaced from the first compartment for receiving the resilient portion of the terminal, and a wire loading slot defined between said first and second compartments for receiving said second wire prior to engagement with said terminal, said compartments having means allowing communication with the loading slot, said second compartment having a cam surface formed thereon for engagement with the resilient portion for moving the second cutting edge toward the first cutting edge as the terminal is inserted into the housing, whereby said cutting edges displace the insulation of the second wire at the loading slot and engage the conductive part thereof.
Claim 2
Dependent Claim
251 words
A connector assembly for electrically connecting a first wire to a second insulation clad wire comprising: a unitary terminal including a relatively rigid portion having a wire trap means for receiving a conductive part of the first wire and a wire piercing side with a first insulation cutting edge formed thereon, said terminal further including a resilient portion spaced from said wire piercing side having a second insulation cutting edge formed thereon facing and movable toward said first cutting edge, the space between said first and second cutting edges defining an insulation displacement slot for receiving said second wire and being spaced a distance not less than the diameter of the conductive part of said first wire; and a housing with an opening through which said terminal is receivable, said housing including a first compartment for receiving the rigid portion of the terminal and said first wire, a second compartment spaced from the first compartment for receiving the resilient portion of the terminal, and a wire loading slot defined between said first and second compartments for receiving said second wire prior to engagement with said terminal, said compartments having means allowing communication with the loading slot, said second compartment having a cam surface formed thereon for engagement with the resilient portion for moving the second cutting edge toward the first cutting edge as the terminal is inserted into the housing, whereby said cutting edges displace the insulation of the second wire at the loading slot and engage the conductive part thereof.
Claim 3
Dependent Claim
24 words
The connector assembly of claim 1 including means cooperating between said housing and terminal for locking the terminal in the housing after insertion thereof.
Claim 4
Dependent Claim
203 words
A connector assembly comprising: an insulation displacement terminal including a relatively rigid portion with a first insulation cutting edge formed thereon and a resilient portion spaced from said rigid portion having a second insulation cutting edge formed thereon facing and movable toward the first cutting edge, the space between said first and second cutting edges defines an insulation displacement slot for receiving a wire and being spaced a distance not less than the diameter of the conductive part of the wire; and a housing with an opening through which said terminal is receivable, said housing including a first compartment for receiving the rigid portion of the terminal and said wire and a second compartment spaced from the first compartment for receiving the resilient portion of the terminal, said compartments having means allowing communication with a loading slot defined therebetween for receiving said wire prior to engagement with said terminal, said second compartment having a cam surface formed thereon for engagement with the resilient portion for moving the second cutting edge toward the first cutting edge as the terminal is inserted into the housing, whereby said cutting edges displace the insulation of the wire at the loading slot and engage the conductive part thereof.
Claim 5
Dependent Claim
203 words
A connector assembly comprising: an insulation displacement terminal including a relatively rigid portion with a first insulation cutting edge formed thereon and a resilient portion spaced from said rigid portion having a second insulation cutting edge formed thereon facing and movable toward the first cutting edge, the space between said first and second cutting edges defines an insulation displacement slot for receiving a wire and being spaced a distance not less than the diameter of the conductive part of the wire; and a housing with an opening through which said terminal is receivable, said housing including a first compartment for receiving the rigid portion of the terminal and said wire and a second compartment spaced from the first compartment for receiving the resilient portion of the terminal, said compartments having means allowing communication with a loading slot defined therebetween for receiving said wire prior to engagement with said terminal, said second compartment having a cam surface formed thereon for engagement with the resilient portion for moving the second cutting edge toward the first cutting edge as the terminal is inserted into the housing, whereby said cutting edges displace the insulation of the wire at the loading slot and engage the conductive part thereof.
