Abstract
Abstract A device for splicing insulated wires such as drop wires comprised of a housing for containing the ends of two insulated wire lengths or sections with the housing adapted to receive a contact member with the ends of said sections extending over and around portions of the contact member and forming a reverse bend. The splice accommodates a two conductor splice. The contact member has a non-conductor portion to separate the conductors of a wire and a plurality of teeth which penetrate the insulation and engage conductors in the wires being spliced and effect electrical continuity between the conductors. A closure member is placed in the housing over the wires and the contact member with force being applied to the closure member to cause the teeth to penetrate the insulation and make the connection. Means are provided on the housing to hold the closure member in engagement with the wires to maintain the clamped electrical engaged condition of the wires and the assembly. A viscous pressure flowable insulating material is in the housing and flows under the clamping pressure to fill the voids and surround the splice forming a substantially waterproof structure excluding moisture and air for a long life corrosion resistant splice.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
An electrical wire splice comprising: a. a body member having spaced apart side walls and a web therebetween and having opposed ends with openings sized for receiving a wire therethrough; b. a clamp member disposed between said wall walls being movable toward said web; c. an anchor member received between said member having opposite ends adjacent the opposite ends of said body and having conductor means cooperating therewith; d. wire members each extending through a respective one of said body openings and reversely bent around a respective end of said anchor member with said wires electrically engaging said conductor means effecting electrical continuity therebetween; e. cooperating means on said body and said clamp member holding the same in clamping engagement with said wires and said anchor member and holding said wires in electrical contact with said conductor means.
Claim 2
Dependent Claim
138 words
An electrical wire splice comprising: a. a body member having spaced apart side walls and a web therebetween and having opposed ends with openings sized for receiving a wire therethrough; b. a clamp member disposed between said wall walls being movable toward said web; c. an anchor member received between said member having opposite ends adjacent the opposite ends of said body and having conductor means cooperating therewith; d. wire members each extending through a respective one of said body openings and reversely bent around a respective end of said anchor member with said wires electrically engaging said conductor means effecting electrical continuity therebetween; e. cooperating means on said body and said clamp member holding the same in clamping engagement with said wires and said anchor member and holding said wires in electrical contact with said conductor means.
Claim 3
Dependent Claim
75 words
The splice as set forth in claim 1 wherein: a. said wires including conductors surrounded by insulation; b. said anchor member being of electrically insulating material having said conductor means therein and extending longitudinally thereof, said conductor means including a plurality of insulation penetrating teeth extending from said anchor member with certain of said teeth extending from opposed surfaces of said anchor member in opposed directions and penetrating said wire insulation and contacting said conductors.
Claim 4
Dependent Claim
82 words
The splice as set forth in claim 2 wherein: a. said anchor member has opposed faces and has recessed portions in said opposed faces with each said recessed portion extending from a respective opposed end of said anchor member and terminating short of a longitudinal center of said anchor member, said recessed portions being in opposed relation; and b. certain of said teeth extending from one of said recessed portions and the remaining said teeth extending from the other said recessed portion.
Claim 5
Dependent Claim
81 words
The splice as set forth in claim 3 including: a. tongue members on at least one of said body member and said clamp member and positioned adjacent respective ends of said body and overlying the body openings, each of said tongue having a through aperture receiving one of said wires therethrough; b. an ear on each of said tongues and extending away from said body and engaged with a respective wire preventing same from contacting the edge defining said through aperture.
Claim 6
Dependent Claim
29 words
The splice as set forth in claim 4 including: a. a pressure flowable insulating material in said body encapsulating the electrical connection between said wires and said conductor means.
Claim 7
Dependent Claim
64 words
The splice as set forth in claim 4 wherein: a. said clamp member has a pair of spaced apart ribs each adjacent a respective one of said side wall; and b. said cooperating means includes tangs on said side walls bent over in engagement with respective one of said ribs holding said clamp member in clamping engagement with said wires and said anchor member.
Claim 8
Dependent Claim
70 words
The splice as set forth in claim 6 including: a. means cooperating with said body and said clamp member for limiting relative longitudinal movement therebetween, said means including notches in said ribs with each said notch receiving a respective one of said tangs therein wherein engagement between said tangs and edges defining said notches prevents said relative longitudinal movement; and wherein b. said body being an open top channel member.
Claim 9
Dependent Claim
118 words
The splice as set forth in claim 4 wherein: a. said wires each including a pair of conductors surrounded by insulation with a groove in the insulation between said conductors; b. said conductor means includes a pair of conductor members in side by side electrically isolated relation in said anchor member and extending longitudinally thereof, each said conductor meMber having a plurality of said teeth thereon, each said conductor member and respective teeth effecting electrical continuity between one conductor of each said wire, said teeth on each conductor member being in a row; and c. a rib on each said recessed portion positioned between the rows of teeth and received in the groove of a respective said wire.
