Terminal tab strip and applicator

Claim 2

An applicator for weld tab or like components to be staked into a printed circuit board or like panel, comprising a feeding, severing and staking assembly having a strip providing said components, said assembly including a strip feeding and component cut-off unit, and a staking unit, a pivotal connection between said units, and operating means for successively moving said units relative to one another about said connection and bodily together in linear movement for a strip severing, component cutoff and staking stroke, said operating means including a toggle linkage operatively connecting said units to one another and to a linearly travelling operator bar of said operating means for a pivotal strip clamping action of said units during a staking stroke of said operator bar.

Claim 3

The applicator of claim 1, in which said operator bar carries one of said units in a linear travel, said operating means including a power member to reversibly actuate said bar for said travel and said units for a relative pivotal movement, said toggle linkage including a first arm pivotally connected between said operator bar and said power member, and a second arm pivotally connected between said first arm and the other unit of said assembly, and means controlling the operation of said power member and toggle linkage on said units to produce sequential actions of the latter to clamp a strip component therebetween and to cut and stake an end component of said strip in said panel.

Claim 4

ThE applicator of claim 2, including means providing the pivotal action of said linkage prior to the linear travel of said operator bar.

Claim 5

The applicator of claim 3, and further comprising drag means acting frictionally on said operator bar to delay its said linear travel pending an operation of said toggle linkage by said power member to pivotally operate said units relative to one another.

Claim 6

The applicator of claim 1, and further comprising means operated in timed relation to the operation of said units to position said strip in a different relation to said units after a staking of an end strip component by the units.

Claim 7

The applicator of claim 1, and further comprising means operated in timed relation to the operation of said linkage and operator bar to position said strip in a different relation to said units after a staking of an end strip component by the units.

Claim 8

The applicator of claim 2, and further comprising means operated in timed relation to the operation of said linkage and operator bar by said power member to position said strip in a different relation to said units after a staking of an end strip component by the units.

Claim 9

The applicator of claim 3, and further comprising means operated in timed relation to the operation of said linkage and operator bar by said power member to position said strip in a different relation to said units after a staking of an end strip component by the units.

Claim 10

The applicator of claim 4, and further comprising means operated in timed relation to the operation of said linkage and operator bar by said power member to position said strip in a different relation to said units after a staking of an end strip component by the units.

Claim 11

Apparatus for staking weld tabs or like connector components to a printed circuit board or like panel, comprising means to manipulate a strip presenting a longitudinally articulated series of such components to position the latter to be clamped in proper relation to the length of said series and to said panel for a subsequent staking step, means to clamp the strip as thus positioned and to advance the clamped strip toward the plane of said panel, means operating in conjunction with said clamping and advancing means for severing from the strip the end-most component of said strip and staking that component to the panel, all of said aforementioned means being operated for said actions by a common reversing stroke power device in a stroke of the latter, such device being operatively connected to said clamping and advancing means to effect said actions progressively in the named order, the operative connection of said device to said clamping and advancing means occasioning the unclamping of the unsevered portion of said strip at the outset of a reverse retractal stroke of said device, said strip manipulating means being operable to advance said strip in said one stroke and including means acting on said strip during said reverse stroke to prevent retraction of the unsevered and unclamped strip portion in the same direction.

Claim 12

Apparatus for staking weld tabs or like connector components to a printed circuit board or like panel, comprising means to manipulate a strip presenting a longitudinally articulated series of such components to position the latter to be clamped in proper relation to the length of said series and to said panel for a subsequent staking step, means to clamp the strip as thus positioned and to advance the clamped strip toward the plane of said panel, means operating in conjunction with said clamping and advancing means for severing from the strip the end-most component of said strip and staking that component to the panel, all of said aforementioned means being operated for said actions by a common reversing stroke power device in a stroke of the latter, such device being operatively connected to said clamping and advancing means to effect said actions progressively in the named order, the operative connection of said device to said clamping and advancing means occasioning the unclamping of the unsevered portion of said strip at the outset of a reverse retractal stroke of said device, said strip manipulating means being operable to advance said strip in said one stroke and including means acting on said strip during said reverse stroke to prevent retraction of the unsevered and unclamped strip portion in the same direction.
