Abstract
Abstract A carrier for components to be soldered includes an upper frame (1) pivotally connected to a lower frame (3). The upper frame includes longitudinal grid members (14) interlocked with transverse grid members (15) to define recessed zones (31) with stepped corners to locate the components. The lower frame (3) has slidably mounted strips (9) with projections (21) which engage the components when the lower frame is pivoted to a closed condition.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
147 words
Apparatus for holding electrical or electronic components, comprising a first set of parallel elongate members (14) and a second set of parallel elongate members (15) intersecting the first set so as to form a grid (5) of a plurality of quadrilaterals, the corners of which are the points of intersection (30) and alternate quadrilaterals in any direction constituting a zone (31) for receiving a component, wherein each of the four members defining such a zone is provided with a pair of facing abutments (34, 38), one outside each of its points of intersection, so as to resist lateral movement of a component positioned in the zone, and between each such pair of abutments is provided at least one portion (35, 39) to restrict vertical movement in the one vertical direction, the carrier also being provided with means (3) to restrict vertical movement in the other vertical direction.
Claim 2
Dependent Claim
147 words
Apparatus for holding electrical or electronic components, comprising a first set of parallel elongate members (14) and a second set of parallel elongate members (15) intersecting the first set so as to form a grid (5) of a plurality of quadrilaterals, the corners of which are the points of intersection (30) and alternate quadrilaterals in any direction constituting a zone (31) for receiving a component, wherein each of the four members defining such a zone is provided with a pair of facing abutments (34, 38), one outside each of its points of intersection, so as to resist lateral movement of a component positioned in the zone, and between each such pair of abutments is provided at least one portion (35, 39) to restrict vertical movement in the one vertical direction, the carrier also being provided with means (3) to restrict vertical movement in the other vertical direction.
Claim 3
Dependent Claim
38 words
Apparatus as claimed in claim 1 wherein there are provided two upwardly directed steps (35, 39) between the facing abutments (34, 38) on each member(14, 15), with the portion(36, 40) of the member between the steps being recessed.
Claim 4
Dependent Claim
17 words
Apparatus as claimed in claim 2 wherein a step (35, 39) is provided adjacent each abutment(34, 38).
Claim 5
Dependent Claim
38 words
Apparatus as claimed in claim 3 wherein each member (14, 15) is provided along its length with a plurality of equally spaced recesses (33, 37) each side of which is stepped, the members intersecting between the steps(35, 39).
Claim 6
Dependent Claim
18 words
Apparatus as claimed in any preceding claim wherein the grid comprises continuous members (14, 15) which are interlocked.
Claim 7
Dependent Claim
50 words
Apparatus as claimed in claim 5 wherein the members (14, 15) are interlocked by providing one set of members (14) with downwardly facing slots (22) for half the depth of the members, and the other set of members(15) with upwardly facing slots(24), again for half the depth of the members(15).
Claim 8
Dependent Claim
16 words
Apparatus as claimed in claim 5 or 6 wherein the members (14, 15) are thin strips.
Claim 9
Dependent Claim
88 words
Apparatus for holding electrical or electronic components including means (1) for holding a plurality of components in an array and restricting them against movement in lateral directions and in one vertical direction, wherein means (3) for restricting vertical movement in the other vertical direction comprises a plurality of parallel elongage members(9) each provided along its length with a plurality of projections (21) adapated to engage the components and each mounted to a frame (3) by means of a lug (20) and slot .(19) arrangement allowing for thermal expansion.
Claim 10
Dependent Claim
88 words
Apparatus for holding electrical or electronic components including means (1) for holding a plurality of components in an array and restricting them against movement in lateral directions and in one vertical direction, wherein means (3) for restricting vertical movement in the other vertical direction comprises a plurality of parallel elongage members(9) each provided along its length with a plurality of projections (21) adapated to engage the components and each mounted to a frame (3) by means of a lug (20) and slot .(19) arrangement allowing for thermal expansion.
Claim 11
Dependent Claim
26 words
Apparatus as claimed in claim 8 wherein the projections (21) are grouped in pairs longitudinally so as to be positioned on either side of a component.
Claim 12
Dependent Claim
17 words
Apparatus as claimed in claim 8 or 9 wherein the projections (21) are grouped in pairs laterally.
Claim 13
Dependent Claim
34 words
Apparatus as claimed in claim 10 wherein the laterally grouped pairs (21) are provided by pairs of elongate members (9) each mounted to the frame (3) by a lug (20) and slot (19) arrangement.
Claim 14
Dependent Claim
27 words
Apparatus as claimed in any of claims 8 to 11 wherein the elongate members (9) are mounted on posts (8) which project downwardly from the frame members.
Claim 15
Dependent Claim
61 words
Apparatus as claimed in any of claims 8 to 12 wherein the elongate members (9) are provided with slots--(19) having enlarged portions (46) which can be moved over the heads (49) of the lugs (20) and narrower portions (47) which, on relative movement of the lugs and members during assembly, will locate the members whilst providing sufficient room for thermal expansion.
Claim 16
Dependent Claim
49 words
Apparatus as claimed in any of claims 8 to 13 wherein the means (1) for holding the plurality of components in an array and restricting them against movement in lateral directions on the said one vertical direction, comprises the means set forth in any of claims 1 to 7.
