Abstract
Abstract Releasably removable and adjustable polarizing means (30) for mateable assemblies (10,20) and comprising a keyway (72) disposed in one assembly and a polarizing pin (40) mounted in a slotted bore disposed in the other assembly, the pin having a roud base (42) and a polarizing key (52) extending axially from the base, the base being provided with a plurality of longitudinally disposed projections (50) extending radially therefrom. A transverse cross-section of the slotted bore is somewhat smaller than the transverse cross-section of the base so as to provide a tight interference fitment therebetween. Another embodiment includes the one assembly having a like slotted bore and provides a multisided insert (60) having the keyway disposed therein, the insert and base being interchangeably fitable within the slotted bore of either assembly (10,20).

Claim 1
Independent Claim
284 words
Polarizing means for mateable units such as electrical connectors (100) of the type having first (10) and second (20) engageable assemblies carrying mateable electrical contacts comprising a round bore (14) disposed in the first assembly (10) a polarizing key (52) removably mounted in the first assembly and a keyway (72) disposed in the second assembly (20), the key (52) and the keyway (72) having opposite ends with one end (55) of the key (52) being interfitable within the keyway (72) when properly oriented and in confronting relation on a common axis, an adjustable multi-sided base (42) having top (43) and bottom (47) portions and a generally symmetrical transverse cross-section, said base (42) extending from the other end (53) of the key (52) and adapted to be mounted in the first assembly bore (14) characterized in that the polarizing means further comprises a plurality of projections (50) extending outwardly from the sides of the base, each projection (50) being longitudinally disposed between the top and bottom portions (43,47) of and spaced from each other around the sides of the base, said bore (14) in the first assembly (10) including a plurality of slots (16) extending outwardly therefrom and defining registrable positions for receiving the projections (50), a transverse cross-section of the bore (14) and its slots (16) corresponding to but being somewhat smaller than the transverse cross-section of the base (42) and its projections (50), whereby when the base is inserted into the bore, a tight interference fit is developed between the sides of the base and the bore and the projections and slots, whereby depending on the orientation of the base (42) and the keyway (72), the assemblies either engage or do not engage.
Claim 2
Dependent Claim

Polarizing means for mateable units such as electrical connectors (100) of the type having first (10) and second (20) engageable assemblies carrying mateable electrical contacts comprising a round bore (14) disposed in the first assembly (10) a polarizing key (52) removably mounted in the first assembly and a keyway (72) disposed in the second assembly (20), the key (52) and the keyway (72) having opposite ends with one end (55) of the key (52) being interfitable within the keyway (72) when properly oriented and in confronting relation on a common axis, an adjustable multi-sided base (42) having top (43) and bottom (47) portions and a generally symmetrical transverse cross-section, said base (42) extending from the other end (53) of the key (52) and adapted to be mounted in the first assembly bore (14) characterized in that the polarizing means further comprises a plurality of projections (50) extending outwardly from the sides of the base, each projection (50) being longitudinally disposed between the top and bottom portions (43,47) of and spaced from each other around the sides of the base, said bore (14) in the first assembly (10) including a plurality of slots (16) extending outwardly therefrom and defining registrable positions for receiving the projections (50), a transverse cross-section of the bore (14) and its slots (16) corresponding to but being somewhat smaller than the transverse cross-section of the base (42) and its projections (50), whereby when the base is inserted into the bore, a tight interference fit is developed between the sides of the base and the bore and the projections and slots, whereby depending on the orientation of the base (42) and the keyway (72), the assemblies either engage or do not engage.
Claim 3
Dependent Claim
36 words
Polarizing means according to Claim 1, characterized in that each pair of adjacent sides defining the multi-sided base (42) have a common longitudinal edge, one projection (50) being disposed along each of said common longitudinal edges.
Claim 4
Dependent Claim
210 words
Polarizing means according to Claim 1 wherein the second assembly (20) is provided with a second round bore (24) an adjustable multi-sided insert (60) having top (65) and bottom (69) surfaces and a generally symmetrical transverse cross-section, the keyway (72) extending into the insert (60) from the top surface (65), the insert being adapted t6 be removably mounted in the second bore (24), characterized in that a second plurality of projections (70) extends outwardly from the sides of the insert (60), each of said second projections (70) being longitudinally disposed between the top and bottom surfaces (65,69) of and spaced from each other around the sides of the insert, and in that the second bore (24) in the second assembly (20) includes a plurality of second slots (26) extending outwardly therefrom and defining registrable positions for receiving said second projections (70) a transverse cross-section- of the second bore (24) and its slots (26) corresponding to but being somewhat smaller than the transverse cross-section of the insert (60) and its projections (70), whereby when the insert (60) is inserted into. the second bore (24), a tight interference fit is developed between the sides of the insert (60) and the second bore (24) and second projections (70) and respective second slots (26).
Claim 5
Dependent Claim
49 words
Polarizing means according to Claim 3 characterized in that the transverse cross-section of the base (42) and the insert (60) and of their associated projections (50,70) correspond in size and location, thereby allowing the base or the insert to be inserted in either the first and/or second assembly respectively.
Claim 6
Dependent Claim
21 words
Polarizing means according to any of the preceding claims characterized in that the key (52) and associated keyway (72) are Y-shaped.
Claim 7
Dependent Claim
57 words
Polarizing means according to any of the preceding claims characterized in that the one end (55) of the key (52) and the end of each projection (50,70) disposed adjacent the bottom of the base and the insert respectively is chamfered, thereby facilitating entry thereof into the keyway or into the slots (16,26) of the respective bores (14,24).
