Abstract
Abstract An electrical connector means comprising a plurality of individual units which may be coupled end-for-end to provide a multiple-conductor connecting means of any desired length. Each of the individual units comprises an outer housing of an electrically non-conductive material and defining on its outer surfaces male and female dovetail coupling means so that a plurality of such units can be mechanically connected together. The outer housing defines an axial bore for receiving a metallic connector which includes a conductor clamping means. The housing further defines a transverse bore extending through one sidewall, other than the one defining a dovetail coupling means, into the axial bore. An electrical conductor can be inserted into the transverse bore so that the end of the conductor can be received into and clamped by the clamping means which includes a clamping screw. The conductor clamping means at the end thereof opposite the screw includes a projecting pin which fits into an axial aperture in the housing communicating with the axial bore, thereby permitting such pin to extend out of the bottom of the housing and be inserted into a corresponding aperture in, for example, a printed circuit card.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
209 words
Electrical connector means comprising in combination: an elongate electrically conductive conductor clamping element defining a longitudinal bore extending therein from one end and also a transversely extending bore, securing means in said longitudinal bore and movable along the axis of said longitudinal bore for bearing against a conductor inserted into said transverse bore, a pin projecting axially from said element at its other end, an elongate electrically insulating housing having an internal elongate substantially blind bore extending from one end for slidably receiving said element in the direction of the axis of said blind bore and with said axis of said blind bore being parallel to said longitudinal bore, said housing defining therein a bore transverse to said axis and extending through one sidewall thereof so as to communicate with said internal blind bore of said housing and being also aligned with said transverse bore in said element, an axial aperture in the other end of said housing extending into said blind bore in said housing through which projects said pin when said conductor clamping element is slidably inserted into said internal bore of said housing to permit external electrical connection thereto and thus to a conductor inserted into the aligned transverse apertures in said housing and said element.
Claim 2
Dependent Claim
209 words
Electrical connector means comprising in combination: an elongate electrically conductive conductor clamping element defining a longitudinal bore extending therein from one end and also a transversely extending bore, securing means in said longitudinal bore and movable along the axis of said longitudinal bore for bearing against a conductor inserted into said transverse bore, a pin projecting axially from said element at its other end, an elongate electrically insulating housing having an internal elongate substantially blind bore extending from one end for slidably receiving said element in the direction of the axis of said blind bore and with said axis of said blind bore being parallel to said longitudinal bore, said housing defining therein a bore transverse to said axis and extending through one sidewall thereof so as to communicate with said internal blind bore of said housing and being also aligned with said transverse bore in said element, an axial aperture in the other end of said housing extending into said blind bore in said housing through which projects said pin when said conductor clamping element is slidably inserted into said internal bore of said housing to permit external electrical connection thereto and thus to a conductor inserted into the aligned transverse apertures in said housing and said element.
Claim 3
Dependent Claim
64 words
The electrical connector of claim 1 wherein said conductor clamping element and also said internal blind bore in said housing which receives said element both having mating non-circular configurations permitting insertion of said element into said housing only with at least one predetermined relative orientation to facilitate thereby the alignment of said transverse bore of said element with said transverse bore of said housing.
Claim 4
Dependent Claim
28 words
The electrical connector of claim 1 wherein said conductor clamping element includes an outwardly projecting tab for frictionally retaining said element within said axial bore in said housing.
Claim 5
Dependent Claim
44 words
The electrical connector means of claim 1 wherein said conductor clamping element comprises first and second opposed portions which therebetween define said second transversely extruding bore, and ridges formed on said opposed portions for bearing frictionally against a conductor inserted into said connector means.
Claim 6
Dependent Claim
51 words
The electrical connector of claim 1 wherein said housing defines on opposite exterior sidewalls thereof and at right angles to the sidewall having said transverse bore therein matable female and male interconnecting means respectively for coupling together a plurality of said housings to provide a connecting means of any desired length.
Claim 7
Dependent Claim
47 words
The electrical connector means of claim 5 wherein said interconnecting means permit the slidable interconnection of a pair of said housings in the direction of the axis of said blind bore, and locking means for releasably locking said housings when they are slidably aligned with each other.
Claim 8
Dependent Claim
30 words
The electrical connector means of claim 6 wherein said locking means includes a protuberance on one said housing fitting into a recess on the other of said pair of housings.
Claim 9
Dependent Claim
23 words
The electrical connector means of claim 7 wherein said protuberance is supported on a resilient support which urges said protuberance into said recess.
