Abstract
Abstract An electrical device (2) intended for surface mounting has an insulating body (20) and leads (12) extending from the body (20). Each lead (12) has an integral spring portion and an end portion (50). The insulating body (20) has an aligning or locating stop (66) and the lead (12) adjacent to its end has a lead locating portion (80) biased against the locating stop (66) by the integral spring. The locating stop (66) thus ensures that the extreme ends (14) of the leads (12) will be in aligned coplanar relationship.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
223 words
An electrical device (2) which is intended to be surface mounted on a circuit board surface (4), the device (2) comprising an insulating body (20) having a mounting surface (22) which is opposed to, and proximate to, the circuit board surface (4) when the device (2) is mounted on the circuit board surface (4), a side surface (24) which extends transversely of the mounting surface (22), and a plurality of spaced apart leads (34) which extend from the side surface (24), each of the leads (34) having an adjacent portion (46) which is adjacent to the side surface (24) and an end portion (50) which extends away from the side surface (24), the end portions (50) having contact portions (14) which are connected to circuit board conductors (10) when the device (2) is mounted on the circuit board surface (4), the device (2) being characterized in that: the side surface (24) has at least one locating stop portion (66) and each lead (34) has a lead locating portion (80) which adjoins its end portion (50), the lead locating portions (80) being against the locating stop portions (66) whereby, the lead locating portions (80) are coplanar by virtue of their being against the locating stop portions (66), and the end portions (50) are maintained in coplanar aligned relationship by the lead locating portions (80).
Claim 2
Dependent Claim
223 words
An electrical device (2) which is intended to be surface mounted on a circuit board surface (4), the device (2) comprising an insulating body (20) having a mounting surface (22) which is opposed to, and proximate to, the circuit board surface (4) when the device (2) is mounted on the circuit board surface (4), a side surface (24) which extends transversely of the mounting surface (22), and a plurality of spaced apart leads (34) which extend from the side surface (24), each of the leads (34) having an adjacent portion (46) which is adjacent to the side surface (24) and an end portion (50) which extends away from the side surface (24), the end portions (50) having contact portions (14) which are connected to circuit board conductors (10) when the device (2) is mounted on the circuit board surface (4), the device (2) being characterized in that: the side surface (24) has at least one locating stop portion (66) and each lead (34) has a lead locating portion (80) which adjoins its end portion (50), the lead locating portions (80) being against the locating stop portions (66) whereby, the lead locating portions (80) are coplanar by virtue of their being against the locating stop portions (66), and the end portions (50) are maintained in coplanar aligned relationship by the lead locating portions (80).
Claim 3
Dependent Claim
49 words
A device (2) as set forth in claim 1 characterized in that each lead (34) has a spring portion (48) which is adjacent to its lead locating portion (80), the spring portion (48) functioning resiliently to bias the lead locating portion (80) against the associated locating stop portion (66).
Claim 4
Dependent Claim
44 words
A device (2) as set forth in claim 2 characterized in that flange means (52) are provided on the side surface (24), the flange means (52) being spaced from the side surface (24), the locating stop portion (66) being on the flange means (52).
Claim 5
Dependent Claim
24 words
A device (2) as set forth in claim 3 characterized in that the locating stop portions (66) are edges on the flange means (52).
Claim 6
Dependent Claim
33 words
A device (2) as set forth in claim 3 characterized in that two flange means (52, 54) extend from the side wall (24), each flange means having respective locating stop portions (66, 68).
Claim 7
Dependent Claim
40 words
A device (2) as set forth in claim 2 characterized in that the insulating body (20) has recess means (60) on the side surface (24) thereof, the spring portion (48) of each lead (34) being in the recess means (60).
Claim 8
Dependent Claim
102 words
A device as set forth in claim 6 characterized in that the recess means (60) has opposed first (62) and second (64) recess surfaces, the first recess surface (62) being proximate to the mounting surface (22), the second recess surface (64) being remote from the mounting surface (22), the recess means (60) having a recess mouth (56) and first and second lip portions (66, 68) which adjoin the first (62) and second (64) recess surfaces respectively, the spring portion (48) of each lead (34) being in the recess means (60), the locating stop portions (80) being on the first lip portion (66).
Claim 9
Dependent Claim
26 words
A device as set forth in claim 7 characterized in that the first lip portions (88) are inclined towards the mounting surface of the insulating body.
Claim 10
Dependent Claim
60 words
A device as set forth in claim 8 characterized in that the spring portion (48) of each lead is generally U-shaped and has a first arm (72), a second arm (74), and a bight portion (76), the first arm (72) being proximate to the first recess surface (62), the second arm (74) being proximate to the second recess surface (64).
Claim 11
Dependent Claim
59 words
A device (2) as set forth in claim 9 characterized in that the recess means (60) is defined by first (52) and second (54) flange means extending from the side surface (24) and the U-shaped spring (48) is spring loaded within the recess means (60) with the first said arms (72) spring loaded against the first lip portion (66).
