Machine and Tool Corporation - Inventors: Marvin Kober; Eugene Battaglia - Web page: https://patentgrep.com/patent/US4399844A ## CPC - H05K 13/023: {with bending or straightening of the terminal leads} - H05K: PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS ## Abstract A novel component lead bending and crimping tool comprises a generally triangularly-shaped handle with recessed sides forming grooved raised edges providing plural component positions for forming right-angle bends in its leads. A crimping apparatus is mounted at the wide end of the tool for forming crimps in the wire leads at desired locations. Various slots and holes are provided in the handle and in the crimping apparatus walls to accommodate the wire leads during various wire bending and crimping procedures. ## Claims ### Claim 1 A component lead bending and crimping tool for adjustably bending and crimping one or more of its axial leads, comprising a handle portion having a generally triangularly shaped body portion with converging outer raised edges having plural parallel aligned grooves for receiving the component's oppositely-extending axial leads for transverse bending of its leads, said handle portion further comprising a block having recessed front and back surfaces for receiving the component body when its leads are positioned in one set of aligned grooves, the raised edges formed by the recess on the front surface having a stepped outline forming raised lands of varying width, the raised edges formed by the recess on the back surface having a straight outline forming raised lands of uniform width, the depth of the grooves on the front surface of the handle portion being different from the depth of the grooves on the back surface, the recess on the back surface being sufficiently deep to allow the component body axis to be located below the depth of the grooves on the raised lands on said back surface, means on the tool for receiving and vertical bending of one or more of the component's leads, and means on the tool under control of the user for receiving and crimping one or more of its leads at a preselected location along the lead. ### Claim 2 (depends on 1) A component lead bending and crimping tool as claimed in claim 1, characterized in that an elongated through-slot is formed in the side of the handle portion in a position to accommodate a right-angle bent lead of the component while its other right-angle bent lead is positioned in the lead-receiving means during a crimping operation on said other lead. ### Claim 3 (depends on 1) A component lead bending and crimping tool as claimed in claim 1, characterised in that the vertical bending means comprises a hole adjacent a corner of the tool and sized to receive a component lead. ### Claim 4 (depends on 3) A component lead bending and crimping tool as claimed in claim 3 and further comprising means on the external surface of said tool and located above the said hole for guiding the component during the bending process so that the component is aligned with the said hole. ### Claim 5 A component lead bending and crimping tool for adjustably bending and crimping one or more of its axial leads, comprising a handle portion having a generally triangularly shaped body portion with converging outer raised edges having plural parallel aligned grooves for receiving the component's oppositely-extending axial leads for transverse bending of its leads, means on the tool for receiving and vertical bending of one or more of the component's leads, means on the tool under control of the user for receiving and crimping one or more of its leads at a preselected location along the lead, said crimping means comprising a body portion that is an extension of the handle portion and comprises a compartment having outer walls and inner walls defining a wire lead receiving slot on an outer wall aligned with a lead receiving groove inside the compartment, means forming a crimping gap on one side of the wire when positioned within its receiving groove, means forming a crimping blade on the opposite side of the wire when so positioned, and means for displacing the crimping blade toward and into the crimping gap, said crimping gap forming means comprising means for independently adjusting the gap width. ### Claim 6 (depends on 5) A component lead bending and crimping tool as claimed in claim 5, wherein the crimping gap forming means comprises a first fixed block and a second cooperating moving block, and means for displacing the moving block with respect to the fixed block to adjust the gap width. ### Claim 7 (depends on 6) A component lead bending and crimping tool as claimed in claim 6, wherein the displacing means comprises an elongated screw having a first right hand threaded section for threadingly engaging a similarly threaded hole in the first block and a second left hand threaded section for threadingly engaging a similarly threaded hole in the second block, the screw having a user adjustable end extending external to the compartment. ### Claim 8 A component lead bending and crimping tool for adjustably bending and crimping one or more of its axial leads, comprising a handle portion having a generally triangularly shaped body portion with converging outer raised edges having plural parallel aligned grooves for receiving the component's oppositely-extending axial leads for transverse bending of its leads, means on the tool for receiving and vertical bending of one or more of the component's leads, means on the tool under control of the user for receiving and crimping one or more of its leads at a preselected location along the lead, said crimping means comprising a body portion that is an extension of the handle portion and comprises a compartment having outer walls and inner walls defining a wire lead receiving slot on an outer wall aligned with a lead receiving groove inside the compartment, means forming a crimping gap on one side of the wire when positioned within its receiving groove, means forming a crimping blade on the opposite side of the wire when so positioned, and means for displacing the crimping blade toward and into the crimping gap, said crimping blade comprising one end of a U-shaped flat metal spring mounted in the compartment. ### Claim 9 (depends on 8) A component lead bending and crimping tool as claimed in claim 8, wherein the crimping blade displacing means comprises an external lever journalled on a compartment wall and having a camming portion for engaging the metal spring for displacing the crimping blade when the lever is actuated by a user. ### Claim 10 (depends on 9) A component lead bending and crimping tool as claimed in claim 9, characterized in that the compartment is closed off by a transparent lid through which the compartment interior is visible to the user. ### Claim 11 (depends on 10) A component lead bending and crimping tool as claimed in claim 10, characterized in that adjustable stop means is mounted on a compartment wall for stopping the lever movement and thus controlling the depth of a crimp to be formed in a wire. ### Claim 12 (depends on 11) A component lead bending and crimping tool as claimed in claim 11, characterized in that the stop means comprises an adjustable screw whose end located in the compartment is located in a position to receive and stop the lever camming portion.
