Definitions

  • This invention relates to an improved method of forming wire harness for use in an automobile, particularly, in a wiring harness assembly placed within a limited space such as a door structure, or ceiling space in a room cabinet.
  • a wiring harness assembly placed within a limited space such as a door structure, or ceiling space in a room cabinet.
  • an apparatus for manufacturing the wiring harness assembly is disclosed where insulated wires are placed in a parallel alignment followed by bonding the neigbouring wires so that the wiring harness exhibits a predetermined, desired flattened shape.
  • the wiring harness for motor vehicle is composed of a variety of elements. Those include groups of insulated electric wires, connectors consisting of electrical terminals and plastic housing of connectors, grommet and outer binding materials such as clamps and tapes.
  • a design table with guide-pins is used to manufacture a set of wire harness assembly where an approximate length of insulated electric wire with an electrical terminal in its one end portion is wired along a drawing on the table in which the guide-pins stand aside the trail of wire and desired numbers of wires are set to form a harness configuration.
  • the set of wires are then bundled together by mean of binding materials resulting in a group of an assembled but shapeless wire collection.
  • the above manual method of making an assembled wires therefore, requires a lot of man-hours and wires are likely to be used in excess due to its suspension between neighbouring guide-pins caused by uneven stretching.
  • the product wire harness assembly becomes bulky which finds difficulty when it is intend to use for wiring in a limited space such as in a door structure.
  • the present invention is aimed to solve the above inefficiency in assembling operation and to reduce bulkiness of the product by making a parallel wire alignment and by affording the product with a predetermined specific patten through bonding the neighbouring wires in the alignment.
  • the method of forming wire harness of the present invention comprises the steps of selecting a group of the insulated electric wires to be assembled, clamping the starting ends of the wires in order followed by applying a metallic terminal to each wire end if desired, placing measured and cut wires on a forming table with a program controlled travelling means along the Y axis which is perpendicular to the longitudinal direction of wires X, making a parallel alignment of wires by handling them with a wiring head which consists of a wavering guide and a press mechanism with or without grooves for disentangling wires while the wiring head traces back along axis X, bonding the neighbouring wires as the wiring head proceeds by either thermal fusion of the outer surface of the insulating layer of the wire or utilizing suitable adhesives on the surface of the wire, controlling both the movement of the wiring head along the coordinate X and that of the forming table along the coordinate Y, the wires are shaped into any desired flattened harness pattern which is particularly useful for wiring door harness of motor vehicles.
  • a process layout for forming a wire harness for use in a automobile door harness is explained. It is composed of a wire-forming table (2) having a travelling mechanism along Y axis which is perpendicular to a longitudinal direction X of a group of insulated electric wires to be assembled, and of a wiring head (3) having a wavering mechanism and a press means with or without grooves for wires equipped with heating means.
  • the wiring head (3) hangs over the wire-forming table (2) and is movable along the axis X and thus the table (2) and the wiring head (3) constitute a X-Y plotting element.
  • a wire supply (4) In front of the wire-forming table (2), it is located a wire supply (4), a clamp (5) which is able to turn toward a terminal crimp machine (7), and a cutting machine (6).
  • wire-carrier (8) having clamp mechanism for holding the starting ends of wires, A, insulation remover (9), terminal crimper (10) and applicator for connector housing (11), both applicable to the terminating ends, B, and terminal supplier (12).
  • a group of wires (1) are selected for a set of wiring harness to be assembled. The selection is usually made out of the wires which share a common connector within total harness structure.
  • the wires are drawn out of a wire supply (4) and are held in order by a wire clamp means (5) which is able to turn into a direction perpendicular to the longitudinal direction X of the wires where a terminal crimp elements including wire-insulation remover and terminal crimper (7) with terminal feeder (12) are located.
  • the destined wire ends (B) which is in the opposite side of the staring wire ends (A), is shifted toward Y2 and Y3 direction along axis Y.
  • the wire ends (B) is subjected to extra steps including insulation removal at (9), terminal crimping at (7), and connector housing is attached at (11) and thus flat wire harness is obtained.
  • the starting ends A of the wires are crimped with terminals, and then lead along X axis while the A ends are held by the clamp (5) until it reaches to a cutter (6).
  • a wire carrier (8) proceeds to the cutter (6) and holds the wire end A and the clamp (5) moves back to the original position along axis X while wires are brought to an table end portion (13) where the wire ends A is fixed.
  • Each of the wires are measured by means of dancer-roller passway (14) in length according to their anticipated distance in an assembled harness on the table (2) and is cut by the cutter (6).
  • Fig. 1 (C) illustrates a harness pattern formed by the method of the present invention.
  • a wiring head (3) having a wavering mechanism and a press means is hanging over the wires on the table (2).
  • the wiring head (3) comes down to the table (2) and touches the wire-surfaces in its press means such as a guiding roll (20) with or without grooves for wires.
  • the wires (1) are disentangled and simultaneously the neighbouring wires are bonded together by either thermal fusion in the surfaces of their insulation or using an adhesive.
  • the corner portions R1 and R2 are formed by moving the wiring head (3) and the forming-table (2) into X and Y directions respecitively according to a programmed design for an anticipated harness pattern.
  • Preferred embodiment of the present invention of forming wire harness is that a both-sided adhesive tape having larger width than that of the actual harness pattern to be traced is placed on the wire-forming table (2) along the passage or wires before the wires are lead on the table (2) through wire-guide (3).
  • the tape sticks to the wire surfaces and is useful for as a substrate maintaing the wires (1) on the predetermined position in a parallel alignment until the neighbouring wires are become bonded.
  • the tape can be removed off after the harness is formed in a pattern.
  • a flat harness with integrating unit pattern can be formed in which a number of branches are included in a single pattern.
  • a complexed flat harness is provided by integration of unit harness elements which consist of a group of wires as described in the present invention.
  • FIG. 2 An apparatus for achieving the same object of forming a flat harness with parallel wire alignments is described referring to Fig. 2.
  • the Figure illustrate a front view of the device.
  • To the wire-forming table (2) are equipped two guide rails (17A) and (17B) along which the wire-forming table (2) can be slidably moved in a direction of Y axis.
  • 16A is a rotatable driving rod located in the middle and underneath the table (2).
  • 16B is also a rotatable driving rod to which the hanger (18) of wiring head (3) is attached.
  • the rod is literally the X coordinate and is parallel to the longitudinal wire direction.
  • roller (20) is an indexing roller whose course is directed by a computer program and the other two are ones for disentangling the wires (1) into an parallel alignment between each other.
  • the latter rollers (21A) and (21B) have spaced grooves for wires and are equipped with heating means which are useful for bonding neighbouring wires by thermal fusion. The latter two rollers follow the trail of the former roller (20).
  • the wires (1) are introduced into a hollow pipe (23) and are drawn to the forming-table (2) and are disentangled and bonded together as the three rollers (20), (21A) and (21B) pass over them.
  • index roller (20) has completed its programmed tracing around an desired harness pattern, the wires (1) on the forming table (2) are aligned in parallel showing formed flat pattern of wire harness.
  • wires (1) are lead into their common longitudinal direction X by moving the wiring head (3) which is driven by rotating the driving rod (16B) and also wires (1) are directed toward Y direction by travelling of the forming table (2).
  • wires (1) are directed toward Y direction by travelling of the forming table (2).
  • a flat, two dimensionally plotted wire harness is provided.
  • an accurate harness pattern is achieved.
