Abstract

A motor programming tool is disclosed for associating with a connection block of a motor and sending signals to a programmable controller of the motor, where the connection block includes a plurality of terminals coupled to the controller. The programming tool includes a tool body with an interface generally corresponding with the connection block of the motor, wiring operable to carry the signals, and a plurality of terminal connecting assemblies to associate with the motor terminals. The tool body includes a shiftable locking mechanism operable to selectively secure the tool body relative to the electrical connection block of the motor. The locking mechanism includes a pivotable latch moveable between an open position, wherein the connecting assemblies are freely moveable into and out of contact with the motor terminals, and a closed position, wherein at least a portion of the pivotable latch is in contact with the motor and the connecting assemblies are restricted from moving out of contact with the motor terminals.

Claims

1. A motor programming tool for temporarily associating with an electrical connection block of a motor and sending electrical signals to a programmable controller of the motor, wherein the electrical connection block of the motor houses a plurality of motor terminals coupled to the controller, said programming tool comprising:

a tool body including an interface generally corresponding with the electrical connection block of the motor for selective association therewith;

wiring operable to carry the electrical signals,

said wiring presenting terminal ends disposed in the tool body; and

a plurality of terminal connecting assemblies configured to associate with the plurality of motor terminals, with each connecting assembly operably contacting a respective motor terminal upon association of the tool body with the electrical connection block of the motor,

said tool body including a shiftable locking mechanism operable to selectively secure the tool body relative to the electrical connection block of the motor,

said locking mechanism including a pivotable latch moveable between an open position, wherein the connecting assemblies are freely moveable into and out of contact with the motor terminals, and a closed position, wherein at least a portion of the pivotable latch is in contact with the motor and the connecting assemblies are restricted from moving out of contact with the motor terminals.

2. The motor programming tool as claimed in claim 1, said interface including a shroud configured to receive a portion of the motor therein, said latch being configured to engage the portion of the motor.

3. The motor programming tool as claimed in claim 2, said portion of the motor comprising a motor programming interface controller.

4. The motor programming tool as claimed in claim 1, said latch being yieldably biased into the closed position.

5. The motor programming tool as claimed in claim 1,

said tool body moving in a first direction when the interface is associated with the connection block of the motor and in an opposite second direction when the interface is disassociated with the connection block of the motor,

said latch being configured to prevent movement of the tool body in the second direction when contacting the motor in the closed position.

6. The motor programming tool as claimed in claim 5, said latch including a catch element that at least in part faces the second direction.

7. The motor programming tool as claimed in claim 6, said latch being yieldably biased into the closed position.

8. The motor programming tool as claimed in claim 7,

said latch being pivotal about a pin,

said latch including a manually operable lever portion projecting from the pin,

said latch including an arm portion projecting from the pin in a generally opposite relationship to the lever portion,

said arm portion including the catch element.

9. The motor programming tool as claimed in claim 1;

and

a flexible conduit having a distal end at which the tool body is located,

said wiring extending along the conduit and into the tool body.

10. The motor programming tool as claimed in claim 9,

said tool body including a proximal handle portion connected to the conduit and a distal connector portion that presents the interface.

11. The motor programming tool as claimed in claim 1,

each connecting assembly including a mounting element electrically connected to at least one terminal end of the wiring and a plunger element shiftable relative to the mounting element while maintaining electrical connection therewith.

12. The motor programming tool as claimed in claim 11,

each plunger element being biased toward an extended condition and being yieldably retracted inwardly relative to the extended condition when the tool body is associated with the electrical connection block of the motor to facilitate electrical communication between the tool and motor controller.

13. The motor programming tool as claimed in claim 12,

each connecting assembly including a tool terminal element configured to directly contact and thereby electrically connect to a respective motor terminal upon association of the tool body with the electrical connection block of the motor,

each plunger element being configured to directly contact and thereby electrically connect to a respective tool terminal element, such that each tool terminal element is electrically interposed between the respective plunger element and motor terminal,

each tool terminal element being positioned to cause the respective plunger element to retract from the extended position when in contact therewith.

14. The motor programming tool as claimed in claim 13,

said tool terminal elements being replaceable, with electrical decoupling of each tool terminal element from the wiring requiring only removal from the yieldably biased contact with the respective plunger element.

15. The motor programming tool as claimed in claim 12,

each plunger element being configured to directly contact and thereby electrically connect to a respective motor terminal upon association of the tool body with the electrical connection block of the motor, with contact with the respective motor terminal causing the plunger element to retract from the extended position.

16. The motor programming tool as claimed in claim 1;

and

circuitry being electrically connected to the wiring and including a time-delay relay element,

said time-delay relay element being configured to sense when the connecting assemblies are operably contacting the respective motor terminals, initiate a delay, and then automatically transmit the electrical signals to the motor controller.

17. The motor programming tool as claimed in claim 16,

said delay of the relay being selectively variable.

18. The motor programming tool as claimed in claim 16,

said time-delay relay element initiating a delay of approximately 1.2 seconds before completing a circuit to automatically transmit the electrical signals to the motor controller.

19. The motor programming tool as claimed in claim 16,

said circuitry including a power input connectable to a power source and a programming input connectable to a programming unit that generates the electrical signals.
