Modular cord coupler jack having a disconnection encumbrance

DETAILED DESCRIPTION The foregoing requirements are provided by a cord in accordance with this invention by which available length telephone cords having an overall maximum length in combination can be quickly and easily connected end-to-end as is necessary in a particular installation.
If a wall outlet jack is positioned so that an existing line cord to a proposed telephone set location is of insufficient length, the telephone set is disconnected by removing the modular plug of the line cord from the wall jack.
The disconnected plug of the line cord is inserted into one of two opposed cavities of the coupler jack of this invention, said coupler jack having a modular plug at one end of a stranded conductor line cord of a desired length inserted into its opposing cavity.
The uncoupled end of the stranded conductor line cord is inserted into the jack in the wall outlet.
On the other hand, if the telephone set has been positioned at a location extremely remote from a wall outlet by the use of a line cord in combination with a coupler jack of this invention, and it is desired to move the set closer to the outlet, the stranded conductor line cord is easily removed.
The uncoupled end of that line cord is removed from the wall outlet and the end of the original line cord is unplugged from the coupler jack and inserted into the wall outlet.
A coupler jack for connecting telephone cords which are terminated with modular plugs includes a housing which is made of a dielectric material and which may be assembled from mating parts or which may be unipartite.
The housing has a base and a top with walls extending therebetween to form an externally communicating plug-receiving cavity at each end and a plurality of spaced passageways that extend from one end to the other.
A contact element in the form of a wire having a linear portion is received in each passageway so that the wires are mounted at a predetermined spacing.
Each end portion of each wire is formed into a retroflexed configuration.
The externally communicating cavity at each end of the coupler is adapted to receive a modular plug having terminals which engage aligned ones of retroflexed portions of the contact elements when the plug is inserted into one of the cavities
