Abstract
Abstract An electrical tab receptacle (2) formed from sheet metal has a box-like body (3) with spring arms (7, 8) extending forwardly in convergent manner and having turned out ends (9, 10) defining a divergent entry to a tab receiving space. A latch projection (13) is formed on one arm (8) and presents a rear-facing shoulder in the tab receiving space, arranged to engage a tab recess or aperture (16) of a complementary tab to resist withdrawal of the tab (17) from the receptacle. Outward flexure of the arm (8) serves to release the latch projection (13) and the receptacle (2) is suitably mounted in a housing (1) with the capacity for limited movement in the tab receiving direction between forward and rearward housing shoulders (11, 6). The forward shoulder (11) is formed on its rearward face with a ramp (12) adapted to deflect the arm (8) transversely outwards on rearward movement relative to the receptacle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
206 words
An electrical tab receptacle formed from sheet metal with a box-like body of generally rectangular section and open at an end, the body having spring arms extending forwardly from a pair of opposite sides at that end, the spring arms converging forwardly, and an end of at least one arm being bent outwardly to define a divergent entrance to a tab receiving space between the arms, characterised in that the box-like body (3) is of open-seam form, the seam (4) extending between ends at one side, and a pair of spring arms (7) extending forwardly from that side, one on each side of the seam (4) and at the other side a single spring arm (8) of width corresponding to the overall width of the pair (7), the single spring arm (8) having an outwardly bent end portion (10) and being formed centrally with a latch projection (13) which presents a rear-facing shoulder (15) in the tab receiving space arranged to engage a recess or aperture (16) in a tab (17) when received between the opposing spring arms (7, 8) to resist withdrawal, the single spring arm (8) also being formed with an aperture (14) extending rearwardly of the latch projection (13), to the body (14).
Claim 2
Dependent Claim
206 words
An electrical tab receptacle formed from sheet metal with a box-like body of generally rectangular section and open at an end, the body having spring arms extending forwardly from a pair of opposite sides at that end, the spring arms converging forwardly, and an end of at least one arm being bent outwardly to define a divergent entrance to a tab receiving space between the arms, characterised in that the box-like body (3) is of open-seam form, the seam (4) extending between ends at one side, and a pair of spring arms (7) extending forwardly from that side, one on each side of the seam (4) and at the other side a single spring arm (8) of width corresponding to the overall width of the pair (7), the single spring arm (8) having an outwardly bent end portion (10) and being formed centrally with a latch projection (13) which presents a rear-facing shoulder (15) in the tab receiving space arranged to engage a recess or aperture (16) in a tab (17) when received between the opposing spring arms (7, 8) to resist withdrawal, the single spring arm (8) also being formed with an aperture (14) extending rearwardly of the latch projection (13), to the body (14).
Claim 3
Dependent Claim
83 words
A tab receptacle as claimed in claim 1 mounted in a housing cavity and retained between forward and rearward housing shoulders arranged to permit limited relative movement between the housing and the receptacle in the tab receiving direction, characterised in that the forward shoulder (11) is formed on its rear face (12) with a ramp arranged to engage the arm (8) of the receptacle on relative rearward movement of the housing, to bias the arm (8) with its latch projection (15) transversely outwardly.
Claim 4
Dependent Claim
161 words
An electrical tab receptacle formed from sheet metal with a box-like body of generally rectangular section and open at an end, the body having spring arms extending forwardly from a pair of opposite sides at that end, the spring arms converging forwardly, and an end of at least one arm being bent outwardly to define a divergent entrance to a tab receiving space between the arms, characterised in that pairs of spring arms (25, 26) are formed at opposite sides of the body and a latch projection (27) is formed on one arm of each pair and presents a rear-facing shoulder in the tab receiving space arranged to engage a recess or aperture (28) in a tab (17) when received between the opposing spring arms (25, 26) to resist withdrawal, the latch projections (27) being on opposite sides relatively of the tab receiving space so that the projections (27) engaged the tab aperture (28) at opposite sides and do not interfere.
Claim 5
Dependent Claim
161 words
An electrical tab receptacle formed from sheet metal with a box-like body of generally rectangular section and open at an end, the body having spring arms extending forwardly from a pair of opposite sides at that end, the spring arms converging forwardly, and an end of at least one arm being bent outwardly to define a divergent entrance to a tab receiving space between the arms, characterised in that pairs of spring arms (25, 26) are formed at opposite sides of the body and a latch projection (27) is formed on one arm of each pair and presents a rear-facing shoulder in the tab receiving space arranged to engage a recess or aperture (28) in a tab (17) when received between the opposing spring arms (25, 26) to resist withdrawal, the latch projections (27) being on opposite sides relatively of the tab receiving space so that the projections (27) engaged the tab aperture (28) at opposite sides and do not interfere.
Claim 6
Dependent Claim
37 words
A tab receptacle as claimed in claim 3, characterised in that the latch projections (27) are formed by lateral projections extending from inner sides of the arms (26) and which are bent into the tab receiving space.
Claim 7
Dependent Claim
86 words
A tab receptacle as claimed in claim 4 or claim 3 mounted in a housing cavity and retained between forward and rearward housing shoulders arranged to permit limited relative movement between the housing and the receptacle in the tab receiving direction, characterised in that the forward shoulder (11) is formed on its rear face (12) with a ramp arranged to engage the arms (26) of the receptacle on relative rearward movement of the housing, to bias the arms (26) with its latch projection (27) transversely outwardly.
Claim 8
Dependent Claim
69 words
A tab receptacle and housing as claimed in claim 5, characterised in that the housing is formed with forward shoulders (30) at opposite sides of the cavity, arranged to engage arms (26) at opposite sides of the receptacle, the shoulders (30) being recessed adjacent the arms (25) so that only the arms (26) formed with latch projections (27) are flexed transversely outwards on relative rearward movement of the housing.
Claim 9
Dependent Claim
28 words
A tab receptacle as claimed in claim 5, characterized in that each arm (25, 26) formed with a latch projection (27) has an outwardly bent end portion (29).
