A retention latch mechanism having corresponding retention features and stress reducing members is provided herein. In an example embodiment, the retention latch mechanism comprises a pair of spring arm retention features of a receptacle engageable with a corresponding pair of recessed retention features of an insertable tab and one or more backup spring members for reducing stress within the spring arms during insertion of the tab into the receptacle. The backup spring is positioned adjacent an outward facing surface such that outward lateral deflection of the spring arms deflects the backup spring thereby reducing force within the spring arm. In some embodiments, the backup spring includes any or all of a bent portion of an associated bracket or arm member, a wire, a loop, a complementary spring arm, dual backup springs, elastomeric members and self-lubricating members. Methods of providing retention of a tab within a receptacle are also provided herein.

1. A method of connecting electrical components comprising: providing a first connector having a cavity with one or more retention springs disposed therein and a second connector for insertion into the cavity to electrically couple the first connector with the second connector, wherein the one or more retention springs are slidably engageable with a retention feature of the second connector;receiving the second connector within the cavity of the first connector by displacing the one or more retention springs laterally outward as the second connector is inserted;lubricating the one or more retention springs of the first connector and the retention feature of the second connector by releasing a lubricant from a lubricating member; andengaging the retention feature with the one or more retention springs to impart a retention force to secure the second connector to the first connector when the second connector is mated within the first connector. 2. The method of claim 1, wherein lubricating the one or more retention springs of the first connector and the retention feature of the second connector comprises lubricating an interface between the one or more retention springs of the first connector and the retention feature of the second connector by releasing the lubricant from the lubricating member as the one or more retention springs are laterally displaced outward. 3. The method of claim 2, wherein lubricating the interface comprises contacting the lubricating member with the one or more retention springs as the one or more retention springs are laterally displaced. 4. The method of claim 1, wherein lubricating comprises releasing the lubricant through a porous surface of the lubricating member as the one or more retention springs presses against the lubricating member during outward displacement. 5. The method of claim 1, wherein lubricating comprises releasing the lubricant from a lubricant reservoir within the lubricating member as the one or more retention springs presses against the lubricating member. 6. The method of claim 1, wherein the lubricating member comprises an elastomeric cylindrical member disposed adjacent an outer facing surface of the one or more retention springs. 7. The method of claim 1, wherein each of the one or more retention springs comprises a spring arm, wherein the lubricating member acts as a backup spring when contacted by the spring arm so as to reduce the stress in the spring arm. 8. The method of claim 7, wherein the one or more retention springs comprise a pair of opposing retention springs, the retention feature comprises a pair of retention features, and the lubricating member comprises a pair of lubricating members positioned adjacent outside of the pair of opposing retention springs. 9. The method of claim 8, wherein the pair of lubricating members are provided on a strip, the method further comprising: replacing the pair of lubricating members positioned within a receptacle of the first connector by removing the strip and replacing with another strip having lubricating members provided thereon in pre-determined positions to facilitate insertion of the lubricating members through holes within the receptacle housing. 10. A lubricating component for use with an electrical connector, the lubricating component comprising: a pair of lubricating members for placement adjacent opposing retention springs in a connector receptacle so that insertion of a connector plug tab into the connector receptacle displaces the retention springs to engage the lubricating members, the opposing retention springs being affixed within the connector receptacle so as to engage with corresponding retention features of the connector plug tab when mated within the connector receptacle, wherein each of the lubricating members includes a lubricant releasable upon engagement with the retention springs and acts as a backup spring upon engagement with the retention springs during insertion of the connector plug tab; anda strip on which the pair of lubricating members are attached to facilitate positioning and/or replacement of the pair of lubricating members by positioning the strip on a receptacle housing of the connector receptacle. 11. The lubricating component of claim 10, wherein the strip comprises a thin plastic substrate and each of the lubricating members comprises a head and a shaft, the head being wider than the shaft, wherein the head of the lubricating member is attached to a bottom surface of the strip. 12. The lubricating component of claim 11, wherein each of the lubricating members comprises a porous elastomeric material infused with the lubricant so that the lubricant is released when the lubricating member is contacted by the respective retention spring. 13. The lubricating component of claim 10, wherein the pair of lubricating members are spaced apart on the strip so as to correspond to a pair of holes on the receptacle housing such that positioning of the strip on the receptacle housing inserts the pair of lubricating members into the corresponding pair of holes into position within the connector receptacle. 14. An electronic connector comprising: a receptacle housing that defines a cavity;a plurality of electrical contacts positioned within the cavity;a retention mechanism for releasably coupling an electronic connector plug tab inserted within the cavity, the retention mechanism including first and second opposing retention springs disposed on opposite sides of the cavity, each configured to engage with a retention feature of the connector plug tab when the connector plug tab is mated within the cavity; andfirst and second elastomeric back-up springs positioned within the cavity and spaced apart from the first and second opposing retention springs, respectively, such that each retention spring is disposed between the respective elastomeric back-up spring and the cavity, wherein each of the first and second back-up springs comprise a porous elastomeric material infused with a lubricant and is positioned such that during insertion of the connector plug tab into the cavity, the respective retention spring contacts the back-up spring compressing the elastomeric material thereby releasing the lubricant to the retention spring.
