Claim 5

An electrical terminal which is adapted to be connected to a wire conductor comprising: a one-piece metal member of relatively thin gauge metal stock and which has a forward generally box shaped main body portion and a rearward crimping wing portion which is adapted to be crimped to an electrical connector, the main body portion comprising a generally planar bottom, a pair of spaced sides extending transversely of said bottom, a first upper member defining a deflectable contact arm integral with one of the sides at its upper end and extending transversely thereof toward the other side, and a second upper member defining a deflectable back up spring integral with the other of the sides at its upper end and extending transversely thereof toward the one side and overlying and engaging said contact arm, said deflectable contact arm having a forward end section including a first leg extending downward toward said bottom, a second leg extending upwardly toward a forward end of the terminal and a bight between said legs, said bight having a rounded undersurface which is spaced from said bottom to define a gap and with the bight adapted to slideably engage a mating male blade terminal when the latter is inserted between said bottom and said forward end section, said contact arm deflecting and exerting a force generally normal to the male blade terminal when the latter is connected between said bottom and said forward end section, a substantially rigid tab extending transversely of said other side and being engageable with said contact arm along its underside to control the spacing of said gap between the bight of said forward end section of the contact arm and said bottom, said deflectable back up spring exerting a further generally normal resisting spring force in addition to the spring force exerted by the forward section of the contact arm when mated to a mating male terminal.

Claim 6

An electrical terminal which is adapted to be connected to a wire conductor comprising: a one-piece metal member of relatively thin gauge metal stock and which has a forward generally box shaped main body portion and a rearward crimping wing portion which is adapted to be crimped to an electrical connector, the main body portion comprising a generally planar bottom, a pair of spaced sides extending transversely of said bottom, a first upper member defining a deflectable contact arm integral with one of the sides at its upper end and extending transversely thereof toward the other side, and a second upper member defining a deflectable back up spring integral with the other of the sides at its upper end and extending transversely thereof toward the one side and overlying and engaging said contact arm, said deflectable contact arm having a forward end section including a first leg extending downward toward said bottom, a second leg extending upwardly toward a forward end of the terminal and a bight between said legs, said bight having a rounded undersurface which is spaced from said bottom to define a gap and with the bight adapted to slideably engage a mating male blade terminal when the latter is inserted between said bottom and said forward end section, said contact arm deflecting and exerting a force generally normal to the male blade terminal when the latter is connected between said bottom and said forward end section, a substantially rigid tab extending transversely of said other side and being engageable with said contact arm along its underside to control the spacing of said gap between the bight of said forward end section of the contact arm and said bottom, said deflectable back up spring exerting a further generally normal resisting spring force in addition to the spring force exerted by the forward section of the contact arm when mated to a mating male terminal.

Claim 7

An electrical terminal, as defined in claim 3, and wherein said contact arm and said backup spring adjacent their rearward end have aligned raised portions which are engageable with each other.

Claim 8

An electrical terminal, as defined in claim 3, and wherein said contact arm has rearward end sections which are folded to be juxtaposed to one another so as to increase the rigidity of the rearward end of the contact arm, said rearward end section being engageable with said backup spring when the contact arm is deflected.

Claim 9

An electrical terminal, as defined in claim 3, and wherein said bottom has a flat raised portion located beneath said bight of said forward end section of said contact arm which is adapted to engage one side of a mating blade terminal when the latter is inserted between the bight and said raised portion.
