Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A unipartite electrical terminal for piercing, securing and making electrical contact with a wire having a conductor and outer insulation on said conductor comprising: a body having an opening for receiving said wire and terminal connecting means thereon; a movable member depending from and projecting over said body; said movable member being movable into engagement with said body; first contact means on said body for retentive receipt of said wire and having insulation piercing members for piercing said outer insulation and electrically contacting said conductor upon retentive receipt of said wire; and second contact means on said movable member for engaging said wire and having insulation piercing portions for piercing said outer insulation of said wire and electrically contacting said conductor, said second contact means further including a securement member for locking said second contact means into direct engagement with said first contact means said upon movement of said movable member.
Claim 2
Dependent Claim
151 words
A unipartite electrical terminal for piercing, securing and making electrical contact with a wire having a conductor and outer insulation on said conductor comprising: a body having an opening for receiving said wire and terminal connecting means thereon; a movable member depending from and projecting over said body; said movable member being movable into engagement with said body; first contact means on said body for retentive receipt of said wire and having insulation piercing members for piercing said outer insulation and electrically contacting said conductor upon retentive receipt of said wire; and second contact means on said movable member for engaging said wire and having insulation piercing portions for piercing said outer insulation of said wire and electrically contacting said conductor, said second contact means further including a securement member for locking said second contact means into direct engagement with said first contact means said upon movement of said movable member.
Claim 3
Dependent Claim
28 words
A terminal in accordance with claim 1, wherein said first contact means includes an aperture having wall surfaces, the edges of which serve as said insulation piercing members.
