Abstract

Systems and methods for designing and assembling form boards with attached wire routing devices for use in wire bundle assembly. The assembly method comprises: (a) establishing a coordinate system of a form board having a multiplicity of holes; (b) using a computer system to determine locations of form board devices of different types with reference to the coordinate system of the form board based on engineering data specifying a wire bundle configuration; and (c) fastening the form board devices of different types to respective holes of the form board having centers closest to respective locations determined in step (b). The form board devices may be inserted robotically or manually.

First claim

The invention claimed is:

1. A form board assembly comprising a form board and a first wire routing device fastened to the form board, wherein the form board comprises a perforated plate having a multiplicity of holes, and wherein the first wire routing device comprises:
a first frame having upper and lower arms which are mutually parallel, wherein the lower arm of the first frame has a hole and the upper arm of the first frame has first and second threaded bores;
a first temporary fastener fastened to the hole in the lower arm of the first frame and to a first hole in the form board;
a first post having a shaft with a threaded lower end which is threadably coupled to the first threaded bore in the upper arm of the first frame; and
a second post having a shaft with a threaded lower end which is threadably coupled to the second threaded bore in the upper arm of the first frame,
wherein the shafts of the first and second posts extend upward in parallel with a first gap therebetween, with axes of the shafts being separated by a first distance.

2. The form board assembly as recited in claim 1 , further comprising a second wire routing device fastened to a second hole in the form board, wherein the second wire routing device comprises:
a second frame having upper and lower arms which are mutually parallel, wherein the lower arm of the second frame has a hole;
a second temporary fastener fastened to the hole in the lower arm of the second frame and to the second hole in the form board;
a third post having a shaft with a lower end fastened to the second frame; and
a fourth post having a shaft with a lower end fastened to the second frame,
wherein the shafts of the third and fourth posts extend upward in parallel with a second gap therebetween with axes of the shafts being separated by the first distance, and wherein the first and second wire routing devices are located so that respective axes of the first through fourth posts are positioned at four vertices of a rectangle.

3. The form board assembly as recited in claim 1 , further comprising second, third, and fourth wire routing devices respectively fastened to second, third, and fourth holes in the form board, wherein each of the second, third, and fourth wire routing devices comprises a respective frame having upper and lower arms which are mutually parallel, a respective temporary fastener fastened to the hole in the lower arm of the respective frame and to a respective hole in the form board, and a respective pair of posts separated by the first distance and arranged parallel to the first and second posts of the first wire routing device, wherein the first through fourth wire routing devices are located so that respective axes of four posts of the first through fourth wire routing devices posts are positioned at four vertices of a square having sides of a length equal to a second distance less than the first distance.

4. The form board assembly as recited in claim 1 , wherein:
the first temporary fastener comprises a cylindrical housing having an external annular flange; and
the first frame comprises a fastener retaining block having an arc-shaped groove in which a portion of the annular flange of the first temporary fastener is seated.

5. The form board assembly as recited in claim 4 , wherein the first temporary fastener further comprises a plunger which is slidably coupled to the cylindrical housing, first and second locking pins extending through a hole in the lower arm of the first frame, and a spacer affixed to the cylindrical housing and disposed between respective portions of the first and second locking pins.

6. A form board assembly comprising a form board and first and second wire routing devices fastened to the form board,
wherein the form board comprises a perforated plate having a multiplicity of holes,
wherein the first wire routing device comprises:
a first frame having upper and lower arms which are mutually parallel, wherein the lower arm of the first frame has a hole;
a first temporary fastener fastened to the hole in the lower arm of the first frame and to a first hole in the form board;
a first post having a shaft with a lower end fastened to the first frame; and
a second post having a shaft with a lower end fastened to the first frame, wherein the shafts of the first and second posts extend upward in parallel with a first gap therebetween with axes of the shafts being separated by a first distance, and
wherein the second wire routing device comprises:
a second frame having upper and lower arms which are mutually parallel, wherein the lower arm of the second frame has a hole;
a second temporary fastener fastened to the hole in the lower arm of the second frame and to a second hole in the form board; and
a routing clip comprising:
a base fastened to the upper arm of the second frame;
first and second flexible clip arms configured to bend resiliently; and
first and second hooks respectively connected to or integrally formed with the first and second flexible clip arms,
wherein the first and second hooks have respective outer inclined surfaces configured to displace in opposite directions when a downward-moving object contacts both outer inclined surfaces, thereby causing the first and second flexible clip arms to bend outwardly to enable the second wire routing device to receive the object.

7. The form board assembly as recited in claim 6 , further comprising a wire end holder that comprises:
a third frame having upper and lower arms which are mutually parallel, wherein the lower arm of the third frame has a hole;
a third temporary fastener fastened to the hole in the lower arm of the third frame and to a third hole in the form board; and
a wire clip fastened to the upper arm of the third frame.

8. The form board assembly as recited in claim 7 , wherein the wire clip comprises:
a base; and
first and second prongs made of a material sufficiently flexible that the first and second prongs are configured to separate when pushed apart by an object and then resiliently return to their respective normal positions when the object is removed.

9. The form board assembly as recited in claim 8 , wherein the first and second prongs have mutually confronting toothed surfaces which interengage when the wire clip is closed.

10. The form board assembly as recited in claim 7 , wherein the third temporary fastener comprises a cylindrical housing, a plunger which is slidably coupled to the cylindrical housing, first and second locking pins having respective proximal ends connected to the plunger and respective distal ends extending through an underside of the lower arm of the third frame and through the third hole in the form board, and a spacer affixed to the cylindrical housing and disposed between respective portions of the first and second locking pins.

11. The form board assembly as recited in claim 6 , wherein the first and second hooks have respective inner inclined surfaces configured to displace in opposite directions when an upward-moving object contacts both inner inclined surfaces, thereby causing the first and second flexible clip arms to bend outwardly to enable the object to be removed from the wire routing device.

12. The form board assembly as recited in claim 11 , wherein the outer inclined surfaces have curved profiles and the inner inclined surfaces have linear profiles.

13. The form board assembly as recited in claim 6 , wherein:
the first temporary fastener comprises a cylindrical housing having an external annular flange; and
the first frame comprises a fastener retaining block having an arc-shaped groove in which a portion of the annular flange of
