Abstract
Abstract A tab portion (2) of a folded tab terminal comprises a first layer (12) and a second layer (14). The first layer (12) has a rabbet (16) exposing a length (9) of the second layer (14), the length (9) having been pressed into the rabbet (6) so as to be bisected by the central longitudinal axis (X) of the tab portion (2). A sleeve (8) of spring tempered metal comprising opposed, identical latching tongues (10) is welded about the exposed length (9). As the exposed length (9) is bisected by the central axis (X), the tongues (10) are located in precise symmetry with respect to that axis (X).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
208 words
An electrical terminal for insertion into a cavity (42) in an insulating housing (44) and having an elongate mating portion (2) and a wire connecting portion (6), the mating portion (2) having a central longitudinal axis (X) and having secured snugly there about, a one-piece metal sleeve (8) comprising latching tongues (10) which project obliquely towards the wire connecting portion (6), for engagement with shoulders (50) in the cavity (42); characterized in that the mating portion is in the form of a flat electrical tab (2) comprising first and second superposed layers (12 and 14) of the tab material, the first layer (12) having formed therein a rabbet (16) exposing the second layer (14) so that it provides a reduced cross section length (9) of the tab portion (2); and in that the sleeve (8) which is made of a spring tempered metal, is welded about said reduced cross section length (9) which has been pressed into said rabbet (16) so that said length (9) is bisected by said central axis (X); whereby the latching tongues (10) are located in rotational symmetry with respect to said axis (X), end walls (18 and 20) of the rabbet (16) preventing movement of the sleeve (8) lengthwise of said axis (X).
Claim 2
Dependent Claim
208 words
An electrical terminal for insertion into a cavity (42) in an insulating housing (44) and having an elongate mating portion (2) and a wire connecting portion (6), the mating portion (2) having a central longitudinal axis (X) and having secured snugly there about, a one-piece metal sleeve (8) comprising latching tongues (10) which project obliquely towards the wire connecting portion (6), for engagement with shoulders (50) in the cavity (42); characterized in that the mating portion is in the form of a flat electrical tab (2) comprising first and second superposed layers (12 and 14) of the tab material, the first layer (12) having formed therein a rabbet (16) exposing the second layer (14) so that it provides a reduced cross section length (9) of the tab portion (2); and in that the sleeve (8) which is made of a spring tempered metal, is welded about said reduced cross section length (9) which has been pressed into said rabbet (16) so that said length (9) is bisected by said central axis (X); whereby the latching tongues (10) are located in rotational symmetry with respect to said axis (X), end walls (18 and 20) of the rabbet (16) preventing movement of the sleeve (8) lengthwise of said axis (X).
Claim 3
Dependent Claim
71 words
A terminal according to claim 1, characterized in that the sleeve (8) was applied to said length (9) by wrapping a spring tempered metal blank (8′) there about so that adjacent edge portions (34 and 36) of the blank (8′) define a seam (40) extending longitudinally of the tab portion (2), and by laser welding the edge portions (34 and 36) together at a plurality of points (P) spaced there along.
Claim 4
Dependent Claim
47 words
A terminal according to claim 1 or 2, characterized in that the sleeve (8) is retained against a movement relative to said axis (X) between end edges (18) of the first layer (12) and end edges (20) of walls (22) bent up from the second layer (14).
Claim 5
Dependent Claim
23 words
A terminal according to claim 3, characterized in that root portions (24) of said tongues (10) extend between said bent up portions (22).
Claim 6
Dependent Claim
31 words
A terminal according to any one of the preceding claims characterized in that the outer surface of the sleeve (9) is flush with the outer surface of the tab portion (2).
Claim 7
Dependent Claim
21 words
A terminal according to any one of the preceding claims, characterized in that the spring tempered metal is spring tempered steel.
