Claim 2

A communication line plug coupler for use in a multiline equipment panel for receiving at least two communication line plugs, said coupler providing a primary demarcation point in determining system problems, said coupler comprising: a coupler body integrally formed as a single piece body having a front portion and a rear portion and side portions extending between said front and rear portions, said coupler body having at least one front receptacle formed in a surface of said front portion and at least one rear receptacle formed in a surface of said rear portion; flexible retention means formed on side portions of said coupler body for retaining said coupler in an aperture formed through said multiline equipment panel; said front receptacle and said rear receptacle being located in said coupler for maintaining electrical engagement between plugs inserted respectively therein; said coupler body being formed with keyway grooves along sides of said coupler body for receiving mating key means for joining a plurality of like coupler bodies together in a side-by-side fashion.

Claim 3

A plug coupler according to claim 1 wherein said coupler body is integrally formed of plastic.

Claim 4

A plug coupler according to claim 1 wherein said flexible retention means comprise at least one flexible arm portion having formed thereon at least one protruding tab portion, said arm portion and said tab portion being located and configured such that when said coupler is inserted through said aperture said flexible arm portion flexes slightly opposite the direction which said tab protrudes from said arm permitting said at least one front receptacle to enter the aperture and abut said multiline panel for receiving a plug therein and such that thereupon said arm returns to a relaxed position for engaging said tab against a surface of said panel to retain said coupler in engagement therewith.

Claim 5

A plug coupler according to claim 1 wherein said coupler body has a major axis extending generally parallel to axes extending through said front and rear receptacles, wherein said joining key grooves are formed integral with said coupler body in parallel axial alignment with said major axis and have generally trapezoidal cross sections opening towards the smaller base of said trapezoidal cross sections.

Claim 6

An assembly including at least one communication line plug coupler adapted to snap fit into a complimentary aperture, a panel having at least one aperture formed through the surface thereof for receiving said at least one coupler, said coupler comprising: a coupler body having a front portion and a rear portion; said front portion having at least one front receptacle formed therein and said rear portion having at least one rear receptacle formed therein; one of said front and rear portions abutting said aperture formed in said panel for receiving a matingly engagable plug inserted therethrough; said one of said front and rear portions abutting said aperture having flexible retention means integrally formed thereon for retaining said coupler in engagement through said aperture; said at least one front receptacle and said at least one rear receptacle being integrally formed in said coupler body and located for positioning removably engagable plugs inserted therein for electrical engagement therebetween, said coupler body being integrally formed as a single piece body; said coupler body being formed with keyway grooves along sides of said coupler body for receiving mating key members for joining a plurality of like coupler bodies together in a side-by-side fashion.

Claim 7

An assembly including at least one communication line plug coupler adapted to snap fit into a complimentary aperture, a panel having at least one aperture formed through the surface thereof for receiving said at least one coupler, said coupler comprising: a coupler body having a front portion and a rear portion; said front portion having at least one front receptacle formed therein and said rear portion having at least one rear receptacle formed therein; one of said front and rear portions abutting said aperture formed in said panel for receiving a matingly engagable plug inserted therethrough; said one of said front and rear portions abutting said aperture having flexible retention means integrally formed thereon for retaining said coupler in engagement through said aperture; said at least one front receptacle and said at least one rear receptacle being integrally formed in said coupler body and located for positioning removably engagable plugs inserted therein for electrical engagement therebetween, said coupler body being integrally formed as a single piece body; said coupler body being formed with keyway grooves along sides of said coupler body for receiving mating key members for joining a plurality of like coupler bodies together in a side-by-side fashion.

Claim 8

An assembly according to claim 5 wherein said coupler body is formed of a material having electrical insulating characteristics for electrically insulating said coupler from said panel.

Claim 9

An assembly according to claim 5 wherein said keyway grooves receiving said mating key members are formed on a sealing portion positioned over said coupler for sealing said coupler against detrimental environmental conditions.

Claim 10

An assembly according to claim 5 wherein a plurality of plug couplers are mounted in a common aperture and spaced relative to each other by said keyway grooves formed on said at least one side of each of said couplers and said mating key members engaged in neighboring keyway grooves.
