Abstract
Abstract A wire clamp for a wire bonding machine, wherein the wire clamp includes a pair of relatively shiftable wire-clamping jaws, one of the jaws having a magnet thereon which is normally attracted to a stop and engages the stop when the jaws are open. A coil adjacent to and spaced from the magnet moves the magnet away from the stop to close the jaws when the coil is energized.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
A wire clamp comprising: a support; a pair of wire-clamping jaws mounted on the support, one of the jaws being movable relative to the other jaw; a magnet secured to one of the jaws, said support having a projection thereon, the magnet being attracted to the projection to hold said one jaw away from the other jaw to open the wire-receiving gap therebetween; and means adjacent to the magnet for creating a magnetic field having a magnitude and direction sufficient to cause the magnet to move away from the projection to move said one jaw toward the other jaw to clamp a wire in said gap.
Claim 2
Dependent Claim
106 words
A wire clamp comprising: a support; a pair of wire-clamping jaws mounted on the support, one of the jaws being movable relative to the other jaw; a magnet secured to one of the jaws, said support having a projection thereon, the magnet being attracted to the projection to hold said one jaw away from the other jaw to open the wire-receiving gap therebetween; and means adjacent to the magnet for creating a magnetic field having a magnitude and direction sufficient to cause the magnet to move away from the projection to move said one jaw toward the other jaw to clamp a wire in said gap.
Claim 3
Dependent Claim
30 words
A wire clamp as set forth in claim 1, wherein said magnet comprises a bar magnet, said projection comprising an adjustable stop in the path of movement of the magnet.
Claim 4
Dependent Claim
26 words
A wire clamp as set forth in claim 2, wherein said stop includes a screw, said support having a side member threadably mounting said screw thereon.
Claim 5
Dependent Claim
26 words
A wire clamp as set forth in claim 1, wherein said creating means includes a solenoid having an end spaced from and adjacent to the magnet.
Claim 6
Dependent Claim
49 words
A wire clamp as set forth in claim 4, wherein said support includes a bar, said jaws being adjacent to one end of the bar, the solenoid being adjacent to the opposite end of the bar, said magnet extending longitudinally of the bar between the jaws and the solenoid.
Claim 7
Dependent Claim
57 words
A wire clamp as set forth in claim 5, wherein said one jaw has means intermediate its ends for pivotally mounting said one jaw on said bar, there being means mounting said magnet on said one jaw at the end thereof remote from said gap with the magnet extending away from said jaws and toward said solenoid.
Claim 8
Dependent Claim
19 words
A wire clamp as set forth in claim 6, wherein said magnet is adjustably mounted on said one jaw.
Claim 9
Dependent Claim
27 words
A wire clamp as set firth in claim 5, wherein said projection includes an adjustable stop, said magnet normally engaging said stop when said gap is open.
Claim 10
Dependent Claim
38 words
A wire clamp as set forth in claim 8, wherein said bar has a side member secured thereto and extending upwardly therefrom, said stop including a screw threadably carried by said side member near the upper end thereof.
Claim 11
Dependent Claim
30 words
A wire clamp as set forth in claim 1, wherein said one jaw has means between the gap and the magnet for pivotally mounting said one jaw on the support.
