Abstract
Abstract An integral transmitter and modular jack assembly for a telephone set has a hollow housing for the transmitter and the modular jack molded as one member connected by a web. In one form the axes of the housing transmitter and acoustic chamber at the front end of the transmitter are coaxial and normal to the surface of the handset. In another form, the axes of the housing and transmitter are coaxial, but are normal to the surface of the handset, with the axis of the acoustic chamber normal to the axis of the transmitter. Preferably a circuit pattern of lead frame form, has the spring contact members of the jack formed integral with the connecting leads to the transmitter and the connecting leads to the handset receiver.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
163 words
An integral transmitter and modular jack assembly, for a telephone set, comprising: a housing having a cylindrical bore having a central axis; a transmitter positioned in said bore, said transmitter having a front end and a back end surface; a modular jack extending laterally from said housing, the jack having a rectangular bore having an axis entending normal to said central axis of said cylindrical bore; said modular jack having a back surface extending in a plane parallel to said back end surface of said transmitter; a web extending between said housing and said modular jack, said web being co-planar with said back surface of said jack and a back surface of said housing; spring contact members extending down into said rectangular bore from said back surface of said modular jack; contact members on said back end surface of said transmitter; and a circuit pattern on said web and connected to said spring contact members and to said contact members on said transmitter.
Claim 2
Dependent Claim
163 words
An integral transmitter and modular jack assembly, for a telephone set, comprising: a housing having a cylindrical bore having a central axis; a transmitter positioned in said bore, said transmitter having a front end and a back end surface; a modular jack extending laterally from said housing, the jack having a rectangular bore having an axis entending normal to said central axis of said cylindrical bore; said modular jack having a back surface extending in a plane parallel to said back end surface of said transmitter; a web extending between said housing and said modular jack, said web being co-planar with said back surface of said jack and a back surface of said housing; spring contact members extending down into said rectangular bore from said back surface of said modular jack; contact members on said back end surface of said transmitter; and a circuit pattern on said web and connected to said spring contact members and to said contact members on said transmitter.
Claim 3
Dependent Claim
21 words
An assembly as claimed in claim 1, said circuit pattern and said spring contact members being an integral lead frame structure.
Claim 4
Dependent Claim
19 words
An assembly as claimed in claim 1, including an acoustic chamber extending from said front end of said transmitter.
Claim 5
Dependent Claim
19 words
An assembly as claimed in claim 1, said acoustic chamber being coaxial with the axis of said cylindrical bore.
Claim 6
Dependent Claim
22 words
An assembly as claimed in claim 1, said acoustic chamber having an axis extending normal to the axis of said cylindrical bore.
Claim 7
Dependent Claim
37 words
An assembly as claimed in claim 5, said axis of said cylindrical bore and said axis of said rectangular bore being in a common plane, said axis of said acoustic chamber extending normal to said common plane.
Claim 8
Dependent Claim
39 words
An assembly as claimed in claim 5, said acoustic chamber comprising a semi-circular tapered first portion connected at a small end to the front end of said transmitter and connected at a large end to a circular second portion.
Claim 9
Dependent Claim
26 words
An assembly as claimed in claim 6, including a web extending in a plane parallel to said common plane, between said modular jack and said housing.
Claim 10
Dependent Claim
19 words
