Abstract
Abstract An electrical contact has a portion for securing the contact in a rectangular aperture in a housing, the contact securing portion being a flat flexible plate slotted to define a spring arm and having a projection on a flat side of the plate such that when the contact is inserted into the associated aperture the spring arm and the projection engage two adjacent walls and force the contact securing portion into engagement with a second two adjacent walls thus positioning the contact accurately in the housing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
An elongate contact for an electrical connector comprising a contact portion, a wire connecting portion and a contact securing portion, the contact securing portion being a generally rectangular cross-section flexible flat plate having a through slot extending generally in the axial direction of the contact to define with an edge of the securing portiOn a spring arm, the spring arm having a projection extending laterally of the contact, said spring arm being flexible in the plane of the securing portion, and a dimple being located on a flat side of the securing portion, said projection and dimple extending in mutually perpendicular directions, said slot being disposed nearer one edge than the other edge of the securing portion and said dimple disposed adjacent to the slot and nearer the other edge than the one edge of the securing portion.
Claim 2
Dependent Claim
138 words
An elongate contact for an electrical connector comprising a contact portion, a wire connecting portion and a contact securing portion, the contact securing portion being a generally rectangular cross-section flexible flat plate having a through slot extending generally in the axial direction of the contact to define with an edge of the securing portiOn a spring arm, the spring arm having a projection extending laterally of the contact, said spring arm being flexible in the plane of the securing portion, and a dimple being located on a flat side of the securing portion, said projection and dimple extending in mutually perpendicular directions, said slot being disposed nearer one edge than the other edge of the securing portion and said dimple disposed adjacent to the slot and nearer the other edge than the one edge of the securing portion.
Claim 3
Dependent Claim
76 words
An electrical connector comprising a housing made of insulating material and having a plurality of generally rectangular apertures each of which removably receives a contact as claimed in claim 1, the spring arm engaging a first wall of the respective aperture and the dimple on the flat side of the securing portion engaging an adjacent second wall of the respective aperture to urge the securing portion against adjacent third and fourth walls of the respective aperture.
Claim 4
Dependent Claim
143 words
An elongate contact for an electrical connector comprising a contact portion, a wire connecting portion and a contact securing portion, the contact securing portion being a generally rectangular cross-section flexible flat plate having a through slot extending generally in the axial direction of the contact to define with an edge of the securing portion a spring arm, said slot having a relatively long side extending adjacent the spring arm parallel to the longitudinal axis of the contact securing portion and an opposed parallel relatively short side to assist in maintaining the other edge of the securing portion rigid, the spring arm having a projection extending laterally of the contact, said spring arm being flexible in the plane of the securing portion, and a dimple being located on a flat side of the securing portion, said projection and dimple extending in mutually perpendicular directions.
Claim 5
Dependent Claim
143 words
An elongate contact for an electrical connector comprising a contact portion, a wire connecting portion and a contact securing portion, the contact securing portion being a generally rectangular cross-section flexible flat plate having a through slot extending generally in the axial direction of the contact to define with an edge of the securing portion a spring arm, said slot having a relatively long side extending adjacent the spring arm parallel to the longitudinal axis of the contact securing portion and an opposed parallel relatively short side to assist in maintaining the other edge of the securing portion rigid, the spring arm having a projection extending laterally of the contact, said spring arm being flexible in the plane of the securing portion, and a dimple being located on a flat side of the securing portion, said projection and dimple extending in mutually perpendicular directions.
