Abstract
Abstract Polarizing means for the main parts of a separable electrical connector which carry mating electrical contacts. The polarizing means has two polarizing inserts removably mounted in selected angular positions on the respective connector parts, such inserts having portions which interfit to permit the connector parts to be mated only when the correct connector parts are presented to each other. In the embodiments shown, the polarizing inserts are made of yieldable plastic material, and are of such dimensions as to provide sufficient tolerances to prevent binding between them when the correct connector parts are mated.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
209 words
In a separable electrical connector including bodies carrying mateable contacts the improvement which comprises at least one connector-body polarizing means, said polarizing means including two parts of relatively rigid, though slightly resilient material, each of which is mounted on a respective connector body and is in the form of a rod having a base portion of multisided transverse section and a stem portion projecting longitudinally from the base portion, recesses in the connector bodies which confront and register with each other when the contacts are mated, the recesses having multisided transverse sections corresponding to but somewhat larger than the transverse sections of said base portions of the rods with inwardly extending projections on the walls of the recesses around said base portions for compressively engaging the sides of the latter to center the same in the recesses, hold the same against appreciable angular movement in the recesses and yieldably resist axial movement of the same in the recesses, whereby each recess receives and yieldably retains a said part in any one of a number of angular positions, the stem portion of each said part being so constructed and arranged that the connector bodies are mateable only when such parts are in complementary angular positions in their respective connector bodies.
Claim 2
Dependent Claim
209 words
In a separable electrical connector including bodies carrying mateable contacts the improvement which comprises at least one connector-body polarizing means, said polarizing means including two parts of relatively rigid, though slightly resilient material, each of which is mounted on a respective connector body and is in the form of a rod having a base portion of multisided transverse section and a stem portion projecting longitudinally from the base portion, recesses in the connector bodies which confront and register with each other when the contacts are mated, the recesses having multisided transverse sections corresponding to but somewhat larger than the transverse sections of said base portions of the rods with inwardly extending projections on the walls of the recesses around said base portions for compressively engaging the sides of the latter to center the same in the recesses, hold the same against appreciable angular movement in the recesses and yieldably resist axial movement of the same in the recesses, whereby each recess receives and yieldably retains a said part in any one of a number of angular positions, the stem portion of each said part being so constructed and arranged that the connector bodies are mateable only when such parts are in complementary angular positions in their respective connector bodies.
Claim 3
Dependent Claim
41 words
An electrical connector as defined in claim 1 wherein the base portions of said two parts of the polarizing means have longitudinal openings therethrough, whereby the resiliency of the same in response to the compressive action of said projections is enhanced.
Claim 4
Dependent Claim
64 words
An electrical connector as defined in claim 2 comprising means for securing the connector bodies together with the contacts and polarizing parts in mated relation, including an internally threaded nut fixedly captured in one said body in axial alignment with said recesses and a bolt rotatably captured in the other said body and extending through said polarizing parts into threaded engagement with said nut.
Claim 5
Dependent Claim
25 words
An electrical connector as claimed in claim 1 wherein the said two parts of the polarizing means are of substantially the same size and shape.
Claim 6
Dependent Claim
36 words
An electrical connector as claimed in claim 1 wherein said projections are axially extending ribs on pairs of opposite walls of the recesses, said ribs compressively engaging the base portions of the said parts between them.
Claim 7
Dependent Claim
32 words
An electrical connector as defined in claim 5 wherein said ribs are centrally disposed on the sidewalls of the recesses and centrally engage sidewalls of said base portions of the polarizing parts.
