Abstract

The invention features a universal harness board for wiring harnesses of different configurations. The board is of box-like construction. A plurality of pins are disposed inside the board. The pins are spring biased to extend above the work surface of the board. Each pin has a locking mechanism to hold it in a retracted position until a plunger is depressed to release it to its extended position. The release of certain ones of the pins will provide the desired wiring pattern.

Claims

1. A universal-type harness board having the capacity for fabricating harnesses with different configurations upon said board by changing a pin pattern to accommodate each different configuration, said harness board comprising

a board-like structure having a work surface upon which an array of pins is disposed;

means defining an array of pins positioned about said work surface, each pin of said array being biased in an extended position whereby each pin will project above said work surface, each pin being disposed in a movable sleeve;

individual pin locking means for locking each responsive pin in said array in a retracted position, such that each retracted pin will not substantially extend above said work surface; and

releasing means for individually releasing any of said pin locking means, whereby any pin in said array can be extended above said work surface by depressing the sleeve of said pin to provide a pattern for accommodating each different harness configuration.

2. The universal-type harness board of claim 1, wherein said array means further defines a grid-pattern.

3. The universal-type harness board of claim 1, further comprising an over-lay for covering said work surface.

4. The universal-type harness board of claim 3, wherein said over-lay comprises a sheet having holes in select positions for allowing certain ones of said pins to extend above said work surface to form a desired pattern.

5. The universal-type harness board of claim 1, wherein said pin locking means comprises a ball detent, each pin having means defining a groove for receiving said ball detent, said ball detent holding said pin in a retracted position, when said detent is disposed within said groove.

6. The universal-type harness board of claim 1, wherein said board-like structure has a box-like configuration.

7. The universal-type harness board of claim 6, wherein said box-like configuration is essentially solid.

8. The universal-type harness board of claim 7, further comprising means defining a plurality of wells disposed in said box-like configuration for supporting said pins.

9. The universal-type harness board of claim 6, wherein said box-like configuration is essentially hollow.

10. A universal-type harness board having the capacity for fabricating harnesses with different configurations upon said board by changing pin pattern to accommodate each different configuration, comprising

a board-like structure having a work surface upon while an array of pins is disposed;

means defining an array of pins positioned about said work surface, each pin of said array being biased in an extended position whereby each pin will project above said work surface;

individual pin locking means for locking each respective pin in said array in a retracted position, such that each retracted pin will not substantially extend above said work surface, said pin locking means comprising a ball detent, each pin having means defining a groove for receiving said ball detent, said ball detent holding said pin in a retracted position when said detent is disposed within said groove; and

releasing means for individually releasing any of said pin locking means, whereby any pin in said array can be extended above said work surface to provide a pattern for accommodating each different harness configuration, said releasing means comprising a movable sleeve, each pin being disposed within said movable sleeve, and each sleeve being depressable for displacing said ball detent from said groove, whereby each pin becomes releaseable from its retracted position.

11. The universal-type harness board of claim 10, wherein each pin is biased towards the extended position by a coil spring.

12. The universal-type harness board of claim 10, wherein each sleeve is depressable manually or by a programmable robot arm.

13. The universal-type harness board of claim 10, wherein each sleeve and pin are disposed within a cylindrical housing.

14. A universal-type harness board having the capacity for fabricating harnesses with different configuration upon said board by changing a pin pattern to accommodate each different configuration, said harness board comprising

a board-like structure having a work surface upon which an array of pins is disposed;

array means defining an array of pins positioned about said work surface in a grid pattern, each pin of said array being biased in an extended position whereby each pin will project above said work surface;

individual pin locking means for locking each respective pin in said array in a retracted position, such that each retracted pin will not substantially extend above said work surface;

releasing means for individually releasing any of said pin locking means, whereby any pin in said array can be extended above said work surface to provide a pattern for accommodating each different harness configuration; and

overlay means for covering said work surface, said over-lay means comprising a sheet having holes in select positions for allowing certain ones of said pins to extend above said work surface to form a desired pattern.

15. The universal-type harness board of claim 14, wherein said pin locking means comprises a ball detent, each pins having means defining a groove for receiving said ball detent, said ball detent holding said pin in a retracted position when said detent is disposed within said groove, and said releasing means comprises a movable sleeve, each pin being disposed within said movable sleeve, and each sleeve being depressable for displacing said ball detent from said groove, whereby each pin becomes releasable from its retracted position, each pin being biased towards the extended position by a coil spring, each sleeve being depressable manually or by a programmable robot arm and each sleeve and pin being disposed within a cylindrical housing.

16. The universal-type harness board of claim 14, wherein said board-like structure has a box-like configuration having a plurality of wells disposed therein for supporting said pins.
