Abstract
Abstract A contact retention device is disclosed for positively retaining a contact within a housing in such manner that no special insertion or extraction tools are required to respectively mount and dismount the contact and which will provide an audible indication when the contact is positively latched properly. The subject retention device includes a spring member having one end mounted fixedly in a connector housing and the other end spring biased against a free end of a blade contact with a portion of the spring member projecting beyond the end of the contact to form a contact release tab. The retention device not only serves to secure the contact within the housing but it adds to the resilience of the contact to bias it into engagement with a mating contact.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
122 words
A contact retention device for use in combination with an electrical connector housing and a blade-like electrical contact received therein, said device comprising: a cantilever spring member having a first end fixedly secured in said housing, a profiled release tab on the free end of said member and a pair of latching ears projecting from one surface of said member spaced from said release tab, said latching ears being adapted to engage with shoulders of said contact and said release tab projecting beyond the end of said contact whereby the contact is retained in said housing by engagement of said ears with said shoulders and said contact is released simply by depressing the release tab to disengage said latches from said shoulders.
Claim 2
Dependent Claim
122 words
A contact retention device for use in combination with an electrical connector housing and a blade-like electrical contact received therein, said device comprising: a cantilever spring member having a first end fixedly secured in said housing, a profiled release tab on the free end of said member and a pair of latching ears projecting from one surface of said member spaced from said release tab, said latching ears being adapted to engage with shoulders of said contact and said release tab projecting beyond the end of said contact whereby the contact is retained in said housing by engagement of said ears with said shoulders and said contact is released simply by depressing the release tab to disengage said latches from said shoulders.
Claim 3
Dependent Claim
112 words
In combination with a blade contact mounted in a connector housing in cantilever fashion, a retention device comprising: an elongated member of spring material having a first end profiled to frictionally engage in said housing and a second end having a release tab extending beyond the free end of said blade contact and latching means spaced from said release tab and adapted to engage said contact, said member having a permanent bend intermediate its ends to constantly bias said second end into engagement with said contact whereby said contact is fully seated when engaged by said latching means of said member and is released by depressing said tab to free said latches.
Claim 4
Dependent Claim
112 words
In combination with a blade contact mounted in a connector housing in cantilever fashion, a retention device comprising: an elongated member of spring material having a first end profiled to frictionally engage in said housing and a second end having a release tab extending beyond the free end of said blade contact and latching means spaced from said release tab and adapted to engage said contact, said member having a permanent bend intermediate its ends to constantly bias said second end into engagement with said contact whereby said contact is fully seated when engaged by said latching means of said member and is released by depressing said tab to free said latches.
Claim 5
Dependent Claim
37 words
The combination according to claim 2 wherein: said blade contact includes a pair of shoulders spaced from its leading end; and said latching means includes a pair of tabs projecting from said member to engage said shoulders.
