Electric cable subassembly

A trunk line cable assembly for connecting a module inverter placed in the proximity of a photovoltaic module, comprising:

• an electrical cable with a cable jacket and one or more wires, wherein the cable is stripped in the region of the electrical connector and the wires are stripped to expose and electrically connect the wires at respective wire connection points;
• at least a first and a second housing part, which in the assembled state are joined together to define a dielectric connector housing enclosing the wire connection points;
• and
• wherein the connector housing has a cable inlet opening and a cable outlet opening opposite to the cable inlet opening through which the cable enters the connector housing on a first end and exits on an opposite, second end;
• wherein the connector housing has a second inlet opening through which, in an assembled state, wires of a drop line enter the connector housing and are electrically connected inside the connector housing with the respectively associated wire of the cable in the form of a tee branch;
• wherein the wires of the drop line are connectable to a module inverter;
• wherein strain relief means for the cable are provided at the cable inlet opening and at the cable outlet opening, which are effective when the first and second housing parts are joined together;
• and
• wherein further electrical connectors are mounted at the two ends of the cable facing away from the connector housing for interconnecting a plurality of the trunk line cable assemblies to form a string.

A method for producing an electrical cable assembly with a connector configured to connect a module inverter by a drop line, comprising the steps of:

• providing an electrical cable with a cable jacket and with one or more wires with wire insulations;
• providing first and second mating housing parts with strain relief means for the cable;
• stripping a portion of the cable jacket;
• partially removing the wire insulations in the area of the stripped jacket in order to expose the wires;
• providing a drop line with one or more wires;
• stripping a terminating end of the one or more wires of the drop line;
• electrically connecting the one or more wires of the drop line to the respective exposed one or more wires of the electrical cable to produce one or more wire connection points;
• inserting a portion of the cable including the wire connection points into the first or second housing part;
• placing the other housing part thereon and joining together the first and second housing parts so as to form a dielectric connector housing enclosing the wire connection points,
• wherein the strain relief means dig into the cable jacket when the first and second housing parts are firmly joined together.

An electrical cable assembly with a connector, comprising:

• at least one electrical cable with a cable jacket and one or more wires, wherein the cable is stripped in the region of the connector and the wires are stripped to expose and electrically connect the wires at respective wire connection points;
• and
• at least a first and a second housing part, which in an assembled state are joined together to define a dielectric connector housing enclosing the wire connection points;
• wherein the connector housing comprises strain relief means for the cable which are effective when the first and second housing parts are joined together;
• wherein the connector housing has at least one cable opening which is defined by a cable receiving sleeve on an end face of the connector housing, which encloses the cable at the at least one cable opening like a sleeve;
• wherein the cable receiving sleeve is formed as a separate part from the connector housing, and which is engaged in at least one of the first or the second housing part at an end face of the connector housing when the first and second housing parts are joined together;
• and
• wherein the cable receiving sleeve has holes along a circumference thereof, and wherein the strain relief means extends inwards through the holes to dig into the cable jacket.
