Abstract
Abstract A connecting block for telephone systems comprises insulating supports carrying input and output terminals for connecting the wires of the telephone lines. It comprises a case provided with guides cooperating with ribs formed on insulating plates. Each insulating plate carries on its inner face one input terminal and one output terminal. Each input terminal has an extension which, in the inoperative condition, contacts an extension of the corresponding output terminal. Channels are formed on the plate for facilitating the insertion of the wires having their ends connected to the input terminals, the same applying to the output terminals.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
243 words
A connecting block for telephone systems comprising: a prismatic case having opposed parallel end walls and opposed parallel first and second side walls connecting said end walls, at least one side of said case being open, and a plurality of parallel guide means on the inner face of said side walls, said guide means extending in from said open side and being parallel to said end walls, a plurality of pairs of insulating plates insertable in said case through said open side thereof, said plates being guided by said guide means, the two plates of each pair having inner faces facing one another and opposite outer faces, rows of conductive input terminals and corresponding output terminals between said plates of a pair and secured to at least one of said plates, said terminals having end portions projecting out beyond edges of said plates which are perpendicular to said side walls of said case, and means for electrically connecting said input terminals with corresponding output terminals, one of said plates of each of said pairs of plates having on its outer face a plurality of spaced parallel ribs forming a plurality of parallel channels extending from the vicinity of said projecting end portions of said input and output terminals to one or the other of said side walls to receive wires connected to said projecting end portions of said terminals, and said side walls of the case having openings through which said wires extend.
Claim 2
Dependent Claim
243 words
A connecting block for telephone systems comprising: a prismatic case having opposed parallel end walls and opposed parallel first and second side walls connecting said end walls, at least one side of said case being open, and a plurality of parallel guide means on the inner face of said side walls, said guide means extending in from said open side and being parallel to said end walls, a plurality of pairs of insulating plates insertable in said case through said open side thereof, said plates being guided by said guide means, the two plates of each pair having inner faces facing one another and opposite outer faces, rows of conductive input terminals and corresponding output terminals between said plates of a pair and secured to at least one of said plates, said terminals having end portions projecting out beyond edges of said plates which are perpendicular to said side walls of said case, and means for electrically connecting said input terminals with corresponding output terminals, one of said plates of each of said pairs of plates having on its outer face a plurality of spaced parallel ribs forming a plurality of parallel channels extending from the vicinity of said projecting end portions of said input and output terminals to one or the other of said side walls to receive wires connected to said projecting end portions of said terminals, and said side walls of the case having openings through which said wires extend.
Claim 3
Dependent Claim
39 words
A connecting block according to claim 1, in which said case is open at only one of its sides and has a third side wall connecting said end walls at the side of said case opposite said open side.
Claim 4
Dependent Claim
22 words
A connecting block according to claim 2, in which all of said terminals extend out of said open side of said case.
Claim 5
Dependent Claim
48 words
A connecting block according to claim 2, in which said input terminals extend out of one side of said case and said output terminals extend from the opposite side of said case, said third side wall having openings for terminals extending from said third side of said case.
Claim 6
Dependent Claim
33 words
A connecting block according to claim 2, in which all of said terminals extend out of said third side of said case, said third side wall having openings through which said terminals extend.
Claim 7
Dependent Claim
18 words
A connecting block according to claim 1, in which said prismatic case is open at two opposite sides.
Claim 8
Dependent Claim
33 words
A connecting block according to claim 6, in which said input terminals extend from one open side of said case and said output terminals extend from the opposite open side of said case.
Claim 9
Dependent Claim
26 words
A connecting block according to claim 1, in which said input terminals and said output terminals are secured to the same insulating plate of a pair.
Claim 10
Dependent Claim
35 words
A connecting block according to claim 1, in which said input terminals are secured to one insulating plate of a pair and said output terminals are secured to the other insulating plate of said pair.
Claim 11
Dependent Claim
18 words
A connecting block according to claim 8 or 9, in which said input terminals overlap corresponding output terminals.
Claim 12
Dependent Claim
51 words
A connecting block according to claim 10 in which overlapping portions of said input terminals and output terminals are resilient and are normally in contact with one another, and in which an insulating element is insertable in said case between said overlapping portions to separate said input terminals and output terminals.
Claim 13
Dependent Claim
51 words
A connecting block according to claim 10, in which overlapping portions of said input terminals and output terminals are normally spaced from one another and in which a conducting element is insertable in said case between said overlapping portions to effect electrical conduction between said input terminals and corresponding output terminals.
Claim 14
Dependent Claim
26 words
A connecting block according to claim 9, in which said input terminals and corresponding output terminals are electrically connected with one another by bridge-like extensions thereof.
Claim 15
Dependent Claim
53 words
A connecting block according to claim 1, in which both of said plates of each said pair of plates have on their outer faces a plurality of ribs forming said wire-receiving channels, and in which additional plates of insulating material are insertable in said case between successive pairs of said pairs of plates.
Claim 16
Dependent Claim
45 words
A connecting block according to claim 1, in which at said case has projections projecting from said first and second side walls of said case, said projections providing wire passages to receive said wires extending through said openings in said first and second side walls.
Claim 17
Dependent Claim
34 words
A connecting block according to claim 1, in which pivot studs projecting from said end walls provide for pivotal mounting of said case for pivotal movement about an axis perpendicular to said end walls.
