Abstract
Abstract An electrical connector includes a dielectric body mounting a flexible leaf-type terminal which has a spring contact portion for surface engagement with a contact element of a mating connector component. The body includes a partition-like wall defining oppositely facing sides and an end face thereof. The terminal is fixed adjacent one side of the wall, and the spring contact portion of the terminal is bowed around the end face of the wall and spaced therefrom for flexingly surface engaging the contact element of the mating connector component in a given direction generally perpendicular to the end face of the wall. The terminal has a distal end at the end of the spring contact portion located in a recessed area in the other side of the wall. The distal end thereby preloads the spring contact portion and resists flexing of the spring contact portion if engaged in a direction generally toward the one side of the wall.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
In an electrical connector which includes a dielectric body mounting a flexible leaf-type terminal which has a spring contact portion for surface engagement with a contact element of a mating connector component, the body including a partition-like wall defining oppositely facing sides and an end face thereof, the leaf-type terminal being fixed adjacent one side of the wall, and the spring contact portion of the terminal being bowed around the end face of the wall and spaced therefrom for flexingly surface engaging the contact element of the mating connector component in a given direction generally perpendicular to the end face of the wall, wherein the improvement comprises the terminal having a distal end at the end of the spring contact portion located in a recessed area in the other side of the wall to preload the spring contact portion and to resist flexing of the spring contact portion in a direction generally perpendicular to the end face of the wall if engaged in a direction generally toward the one side of the wall.
Claim 2
Dependent Claim
173 words
In an electrical connector which includes a dielectric body mounting a flexible leaf-type terminal which has a spring contact portion for surface engagement with a contact element of a mating connector component, the body including a partition-like wall defining oppositely facing sides and an end face thereof, the leaf-type terminal being fixed adjacent one side of the wall, and the spring contact portion of the terminal being bowed around the end face of the wall and spaced therefrom for flexingly surface engaging the contact element of the mating connector component in a given direction generally perpendicular to the end face of the wall, wherein the improvement comprises the terminal having a distal end at the end of the spring contact portion located in a recessed area in the other side of the wall to preload the spring contact portion and to resist flexing of the spring contact portion in a direction generally perpendicular to the end face of the wall if engaged in a direction generally toward the one side of the wall.
Claim 3
Dependent Claim
42 words
In an electrical connector as set forth in claim 1, wherein said recessed area in the other side of the wall comprises a notch defining a ledge extending into the wall at a reverse angle toward the end face of the wall.
Claim 4
Dependent Claim
40 words
In an electrical connector as set forth in claim 2, wherein the distal end of the terminal includes a lip portion bent inwardly and at an angle back toward the end face of the wall for seating against said ledge.
Claim 5
Dependent Claim
72 words
In an electrical connector as set forth in claim 1, wherein said terminal includes a generally flat leg portion fixed against said one side of the wall and a spacer leg portion projecting outwardly from the one side of the wall at an end of the flat leg portion, with the spring contact portion being bowed around the end face of the wall from an outer end of the spacer leg portion.
Claim 6
Dependent Claim
35 words
In an electrical connector as set forth in claim 4, wherein said flat leg portion and the distal end of the terminal are disposed in respective grooves respectively in the opposite sides of the wall.
Claim 7
Dependent Claim
217 words
An electrical connector assembly, comprising: a dielectric body including a partition-like wall defining a base, oppositely facing sides, an end face and a reverse angle ledge formed in one of the oppositely facing sides; and a leaf-type terminal including a generally flat leg portion fixed against the other side of the wall, a spacer leg portion projecting outwardly from the other side of the wall at an end of the flat leg portion spaced from the base of the wall, a spring contact portion for surface engagement with a contact element of a mating connector component, the spring contact portion projecting from an outer end of the spacer leg portion in a bowed configuration around the end face of the wall and spaced therefrom for flexingly surface engaging the contact element of the mating connector component in a given direction generally perpendicular to the end face of the wall, and a lip at a distal end of the bowed spring contact portion, the lip being bent inwardly and at a reverse angle back toward the end face of the wall for seating beneath the ledge to preload the spring contact portion and to resist flexing of the spring contact portion if engaged by an extraneous object in a direction generally toward the other side of the wall.
Claim 8
Dependent Claim
217 words
An electrical connector assembly, comprising: a dielectric body including a partition-like wall defining a base, oppositely facing sides, an end face and a reverse angle ledge formed in one of the oppositely facing sides; and a leaf-type terminal including a generally flat leg portion fixed against the other side of the wall, a spacer leg portion projecting outwardly from the other side of the wall at an end of the flat leg portion spaced from the base of the wall, a spring contact portion for surface engagement with a contact element of a mating connector component, the spring contact portion projecting from an outer end of the spacer leg portion in a bowed configuration around the end face of the wall and spaced therefrom for flexingly surface engaging the contact element of the mating connector component in a given direction generally perpendicular to the end face of the wall, and a lip at a distal end of the bowed spring contact portion, the lip being bent inwardly and at a reverse angle back toward the end face of the wall for seating beneath the ledge to preload the spring contact portion and to resist flexing of the spring contact portion if engaged by an extraneous object in a direction generally toward the other side of the wall.
Claim 9
Dependent Claim
31 words
The electrical connector of claim 6, wherein said flat leg portion and the lip portion of the terminal are disposed in respective grooves respectively in the opposite sides of the wall.
Claim 10
Dependent Claim
41 words
The electrical connector of claim 6, wherein the base of the wall includes a groove, and the terminal includes a solder tail portion disposed in the groove whereby the solder tail portion is generally flush with the base of the wall.
