Abstract

A low profile modular telephone receptacle (15) is shown. A unitary housing (16) having a pair of transverse support members (35, 36) is provided. A top plate (17) having the necessary plurality of conductors (20) embedded therein is also provided. During assembly, the ends (22, 25) of the conductor are bent to predetermined angles (62, 65) and the top plate is joined to the bottom plate by ultrasonic welding. The resultant receptacle is one in which a minimum height dimension (h) above the necessary height dimension of the opening (18) to accept a standard modular plug is provided. In the preferred method of construction, the top plates (17) are injection molded onto continuous strands of filaments to form the conductors (20). A plurality of slots (55, 56) are provided at one end of the top plate to guide the conductors corresponding openings (46) in the bottom plate when the ends of the conductors forming a terminal set for connecting the receptacle to a utilization circuit are fabricated.

Dependent claims

A low profile modular receptacle for modular telephone plugs comprising in combination:

a housing comprising a pair of side walls, a bottom plate connected to said side wall, said bottom plate including a plurality of slots in the rear end thereof;
a first transverse support member extending between said side walls and including a portion extending above said side walls;
a second transverse support member extending between said side walls below said first transverse support member and forward of a rear end of a top plate;
said top plate being constructed of an electrical insulating material engaging said first transverse support member and connected to said side walls;
a plurality of longitudinally extending elongated conductors embedded in said top plate so as to be completely surrounded by said insulating material over a substantial portion of the entire length of said top plate and so that said insulating material forming the upper surface of said top plate completely covers said conductors;
the rear ends of said plurality of conductors being bent downwardly and engaging said plurality of slots in said bottom plate, said top plate including a plurality of slots below said plurality of conductors characterized by a projection onto said bottom plate substantially equal to said plurality of slots in said bottom plate;
the front ends of said plurality of conductors being bent downwardly and backwardly behind said second transverse support member and being urged against the top of said second transverse support member.

A method of constructing a modular receptacle comprising the steps of:

forming a housing comprising a bottom plate, said bottom plate including a plurality of openings in a rear portion thereof, a pair of side walls connected to said bottom plate, a first transverse support member extending between said side walls and including a portion extending above said side walls, and a second transverse support member extending between said side walls below said first transverse support member;
providing a plurality of elongated conductive filaments;
molding a plurality of top plates onto said plurality of elongated conductive filaments so that said filaments are embedded within said plurality of top plates and are extended longitudinally from each end of said plurality of top plates;
cutting said plurality of elongated filaments between each of said top plates to provide said top plate having a plurality of conductors embedded therein, the remaining portions of said elongated conductive filaments forming said plurality of conductors;
providing a set of slots at each end of said top plate below said plurality of conductors for guiding said plurality of conductors into a predetermined spatial relationship in response to said plurality of conductors being urged downwardly;
bending the rear ends of said plurality of conductors downwardly to a first angle within a first predetermined range of angles;
bending the front ends of said plurality of conductors downwardly and backwardly to a second angle within a second predetermined range of angles;
placing said top plate over said housing in engagement with said first transverse support member and said pair of side walls guiding said rear ends of said plurality of conductors into said plurality of openings and guiding said front ends of said plurality of conductors so as to be urged against said second transverse support member;
and
securing said top plate to said housing.
