Abstract
Abstract A connector ensure the wired connection of a piece of equipment in series with a multiconductor cable for transmitting low currents. A support block (5) has a plate on which through and closed end grooves are formed respectively for the passage of the wires of the cable (2) and wires (3A, 3A') for connecting equipment in series. The closed end grooves be adjacent one of the through grooves, at the level of a connection piece (6) partially housed in these two grooves for interconnecting wires. Each of the through grooves (20A) is provided with a median cavity (21) which interrupts the grove locally and which receives a wire cutting device means (6C). The two connection pieces housed in the same through groove are situated on each side of the cavity (21) and each allows the connection of a second different wire (3A, 3A').

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
262 words
Connector for wiring up a piece of equipment in series with a first cable (2) via a second cable (3), both for transmission of low electrical currents, said first cable comprising at least a pair of first, insulated conducting wires (2A) and a first electromagnetic screen metal sheath (2B) to which a ground wire (2C) is electrically connected, said second cable including second, insulated conducting wires (3A) and a second electromagnetic screen metal sheath (3B), wherein said connector comprises a support block having a plate, through grooves (20A, 20C) formed in said plate for individual passages of each of said first wires from one side of the support block to another side thereof, each of said through grooves being locally interrupted by a median cavity (21) and partly housing two connection pieces (6) each located on a different side of said median cavity, said connection pieces (6) each including cutting means (6C) at a cavity edge of a respective through groove to effect a transverse cut of a said first wire passing through a respective through groove, said plate further including blind end grooves (23A'), each said blind end groove opening on one side of the support block and being closed at one end thereof proximate to one of said through grooves, said one end partly housing one of said connection pieces, each connection pieces being further provided with baring and holding slots (6A) for interconnecting a second wire received in the closed groove end where said connection piece is partly housed, with the first wire situated in an adjacent through groove.
Claim 2
Dependent Claim
262 words
Connector for wiring up a piece of equipment in series with a first cable (2) via a second cable (3), both for transmission of low electrical currents, said first cable comprising at least a pair of first, insulated conducting wires (2A) and a first electromagnetic screen metal sheath (2B) to which a ground wire (2C) is electrically connected, said second cable including second, insulated conducting wires (3A) and a second electromagnetic screen metal sheath (3B), wherein said connector comprises a support block having a plate, through grooves (20A, 20C) formed in said plate for individual passages of each of said first wires from one side of the support block to another side thereof, each of said through grooves being locally interrupted by a median cavity (21) and partly housing two connection pieces (6) each located on a different side of said median cavity, said connection pieces (6) each including cutting means (6C) at a cavity edge of a respective through groove to effect a transverse cut of a said first wire passing through a respective through groove, said plate further including blind end grooves (23A'), each said blind end groove opening on one side of the support block and being closed at one end thereof proximate to one of said through grooves, said one end partly housing one of said connection pieces, each connection pieces being further provided with baring and holding slots (6A) for interconnecting a second wire received in the closed groove end where said connection piece is partly housed, with the first wire situated in an adjacent through groove.
Claim 3
Dependent Claim
70 words
Connector according to claim 1, wherein the through grooves (20A) for the conducting wires (2A) of the first cable are situated parallel and on each respective sides of the through groove (20C) for the ground conductor (20C), the blind end grooves (23A, 23A') being laterally outside the through grooves and opening at the same end of the support block (5) in the vicinity of the opening of the through groove.
Claim 4
Dependent Claim
105 words
Connector according to claim 1, wherein a slide (13), is positioned on the other side of the cavities (21) of the support block (5) from said through grooves (2A) and being housed in a guide (32) within a lid (12) and fixed in a precise positioned above the grooves of the support block (5), slidable in the guide (32) and having two extensions (31B), penetrating into said cavities, each of said extensions having cutting means (22) complementary to said cutting edge at the edge of the cavity in each through groove (20A), for transversely cutting a wire (2A) passing longitudinally through a respective through groove.
