Abstract A gel-filled cap member having a retaining nut member therein for receiving a threaded contact member and a notch, at the open end of the cap member, for at least partially receiving a wire to be connected to the threaded contact member. The cap member may also have a portion at the open end of the cap member which is defined by reinforced wall having an increased cross-sectional area. Further, the cap member may have a plunger portion at the closed end of the cap member for applying increased pressure to the gel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
A cap member for a threaded contact member, the cap member comprising: (A) a hollow body having a closed end, an open end and a wall; (B) a retaining nut member positioned within said body for engaging the threads of the contact member; (C) a gel substantially filling said body, said gel having a cone penetration value from approximately 100 to 350 (10 -1 mm) and an ultimate elongation of at least approximately 200%; said body at the open end having a notch for receiving a wire connected to the threaded contact member; the notch having a first axially disposed portion which is positioned generally parallel to the longitudinal axis of the cap member and a second circumferentially disposed portion which is (a) positioned generally perpendicular to the longitudinal axis of the cap member and (b) as adapted to lift and hold the wire away from the open end when the cap member is rotated about the longitudinal axis.
Claim 2
Dependent Claim
159 words
A cap member for a threaded contact member, the cap member comprising: (A) a hollow body having a closed end, an open end and a wall; (B) a retaining nut member positioned within said body for engaging the threads of the contact member; (C) a gel substantially filling said body, said gel having a cone penetration value from approximately 100 to 350 (10 -1 mm) and an ultimate elongation of at least approximately 200%; said body at the open end having a notch for receiving a wire connected to the threaded contact member; the notch having a first axially disposed portion which is positioned generally parallel to the longitudinal axis of the cap member and a second circumferentially disposed portion which is (a) positioned generally perpendicular to the longitudinal axis of the cap member and (b) as adapted to lift and hold the wire away from the open end when the cap member is rotated about the longitudinal axis.
Claim 3
Dependent Claim
17 words
The cap member of claim 1 wherein said notch is formed by being molded into said body.
Claim 4
Dependent Claim
44 words
The cap member of claim 1 further comprising a plunger portion at the closed end of said body wherein the wall immediately surrounding said plunger portion is flexible, said plunger portion when activated in use causing a decrease in the volume of said body.
Claim 5
Dependent Claim
21 words
The cap member of claim 1 wherein the gel has a cone penetration value between 240 and 280 (10 -1 mm).
Claim 6
Dependent Claim
21 words
The cap member of claim 4 wherein the gel has a cone penetration value between 250 and 270 (10 -1 mm).
Claim 7
Dependent Claim
215 words
A cap member for a threaded contact member comprising: a hollow body having a closed end, an open end and a wall; a retaining nut member positioned within said body for engaging the threads of the contact member; a gel substantially filling said body, said gel having a cone penetration value from approximately 100 to 350 (10 -1 mm) and an ultimate elongation of at least approximately 200%; said body at the open end having a notch area which contains a notch for receiving a wire connected to the threaded contact member; and a reinforced wall adjacent to and surrounding said notch area except for a side of the notch area at the open end of the body wherein the reinforced wall is thicker than the body area outside the reinforced wall and is thicker than any body area in the notched area inside the reinforced wall before the notch is formed and has sufficient thickness to prevent tearing of the body area outside the reinforced wall when the notch is formed or when the notch receives the wire; said body at the closed end comprising a plunger portion wherein the wall immediately surrounding said plunger portion is flexible, said plunger portion when activated in use causing a decrease in the volume of said body.
