Total Claims: 10
Claim 1
Independent Claim
207 words
A telephone terminal connector block for connection between a telephone cord and an interconnecting cable in a receptacle box, said terminal block comprising: a central section having a hole therethrough for the passage of the telephone cord; a plurality of terminal posts on said central section, with at least one terminal post for each wire in a telephone cord to be interconnected; a strain relief post adjacent said terminal post for the mounting of strain relief means thereon for connection to the telephone cord to prevent strain thereof; said central section, said terminal post, and said strain relief post being integrally molded of electrically insulative synthetic polymer composition material; a cover plate having a pair of screw holes for receiving securing screws therethrough and into a wall receptacle box, said cover plate having a pair of respective bosses surrounding said screw holes; and said central section having first and second securing ears integrally formed therewith and extending oppositely therefrom, said securing ears having holes therein engaging around said bosses in press-fit engagement so that the securing screws will pass through said screw holes and securing holes into the wall receptacle box to secure said cover plate and said terminal block with respect to the wall receptacle box.
Claim 2
Dependent Claim
207 words
A telephone terminal connector block for connection between a telephone cord and an interconnecting cable in a receptacle box, said terminal block comprising: a central section having a hole therethrough for the passage of the telephone cord; a plurality of terminal posts on said central section, with at least one terminal post for each wire in a telephone cord to be interconnected; a strain relief post adjacent said terminal post for the mounting of strain relief means thereon for connection to the telephone cord to prevent strain thereof; said central section, said terminal post, and said strain relief post being integrally molded of electrically insulative synthetic polymer composition material; a cover plate having a pair of screw holes for receiving securing screws therethrough and into a wall receptacle box, said cover plate having a pair of respective bosses surrounding said screw holes; and said central section having first and second securing ears integrally formed therewith and extending oppositely therefrom, said securing ears having holes therein engaging around said bosses in press-fit engagement so that the securing screws will pass through said screw holes and securing holes into the wall receptacle box to secure said cover plate and said terminal block with respect to the wall receptacle box.
Claim 3
Dependent Claim
45 words
The terminal block of claim 1 wherein said strain relief post and said terminal posts have holes therein, said hole in said strain relief post being for reception of a securing screw and said holes in said terminal posts being for reception of terminal screws.
Claim 4
Dependent Claim
26 words
The terminal block of claim 2 wherein said central section is substantially circular and said telephone cord opening is substantially centrally located through said central section.
Claim 5
