Abstract
Abstract A telephone adapter for use with a telephone terminal unit having a plurality of contacts each of which is connected with a telephone wire. The adapter has a housing provided opposite an open side thereof with a transverse wall formed with a plurality of apertures therethrough. The number of apertures corresponds to the number of contacts on the terminal unit with which the adapter is to be used. In the interior of the housing is located a plurality of axially compressible helical contact springs each aligned with one of the apertures and so dimensioned as to frictionally engage a contact pin which is pushed through a respective aperture from the outer side of the housing. A plate member of insulating material is received through the open side in the housing and has at one major surface which faces the springs projecting pins which are each conductively received in an adjacent end of one of the springs, and on the opposite major surface the plate member has contact strips which are each conductively connected with one of the pins and which, when the housing is connected by means of connecting means provided for this purpose with the terminal unit, each engage one of the contacts on the terminal unit.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
172 words
An adapter for use with a telephone terminal unit having a plurality of contacts each connected with a telephone wire, comprising housing means having an interior, an opening, and a transverse wall opposite said opening and which has an inner and an outer side; a plurality of apertures in said wall corresponding to said plurality of contacts and eaCh extending from said outer side to said inner side; contact spring means in said interior and each adapted to be conductively engaged by a contact pin inserted through one of said apertures from said outer side; a plate member of electrically insulating material received in said interior through said opening and having two major surfaces and a corresponding plurality of contact members each exposed at both of said major surfaces; and connecting means for releasably connecting said housing means with a terminal unit so that the latter is at least partly received through said opening, with said contact members each engaging one of said contacts and one of said contact spring means, respectively.
Claim 2
Dependent Claim
172 words
An adapter for use with a telephone terminal unit having a plurality of contacts each connected with a telephone wire, comprising housing means having an interior, an opening, and a transverse wall opposite said opening and which has an inner and an outer side; a plurality of apertures in said wall corresponding to said plurality of contacts and eaCh extending from said outer side to said inner side; contact spring means in said interior and each adapted to be conductively engaged by a contact pin inserted through one of said apertures from said outer side; a plate member of electrically insulating material received in said interior through said opening and having two major surfaces and a corresponding plurality of contact members each exposed at both of said major surfaces; and connecting means for releasably connecting said housing means with a terminal unit so that the latter is at least partly received through said opening, with said contact members each engaging one of said contacts and one of said contact spring means, respectively.
Claim 3
Dependent Claim
92 words
An adapter as defined in claim 1, wherein said apertures each have an outer portion of smaller diameter extending inwardly from said outer side, and an inner portion of larger diameter extending from said inner side to a respective outer portion; said contact spring means comprising a plurality of axially compressible helical contact springs each partially received in and aligned with one of said inner portions and having an outer diameter and an inner diameter which are respectively greater and at least slightly smaller than said smaller diameter of said outer portion.
Claim 4
Dependent Claim
17 words
An adapter as defined in claim 1, wherein said housing means is composed of electrically insulating material.
Claim 5
Dependent Claim
58 words
An adapter as defined in claim 2, wherein said contact members each have one portion projecting from one of said major surfaces for engagement with a respective contact spring, and an other portion conductively connected with said one portion and projecting from the other of said major surfaces for engagement with a respective contact of a terminal unit.
Claim 6
Dependent Claim
29 words
An adapter as defined in claim 4, wherein said one portion are pins each of which is receivable in one of said helical contact springs in conductive engagement therewith.
Claim 7
Dependent Claim
16 words
An adapter as defined in claim 5, wherein said other portions are of substantially strip-shaped configuration.
Claim 8
Dependent Claim
55 words
An adapter as defined in claim 1, in combination with a telephone terminal unit comprising a terminal body, and a plurality of contacts each connectable with a telephone wire and engageable by one of said contact members in electrically conductive relationship therewith in response to releasable connection of said housing means with said terminal unit.
Claim 9
Dependent Claim
38 words
An adapter as defined in claim 7; and further comprising cooperating keying portions on said terminal body and said adapter so that the latter can be releasably connected with said terminal unit only in a predetermined relative orientation.
Claim 10
Dependent Claim
24 words
An adapter as defined in claim 1, wherein said housing means and said plate member are composed at least predominantly of synthetic plastic material.
Claim 11
Dependent Claim
52 words
An adapter as defined in claim 7, in combination with a telephone connector having a plurality of male contact pins each receivable in one of said apertures in conductive engagement with said contact spring means, and a similar plurality of female sockets each conductively connected with one of said male contact pins.
