ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an assembly jig for wire harness to be fastened to a perforated panel In which multiple holes are formed and arranged with predetermined spacing, and to a perforated panel fixture for fastening the assembly jig.
2. Description of Background Information
When assembling a wire harness, a wiring base board is used on which a number of wiring jigs are provided. Consequently, holes are formed at predetermined positions in the base board and a lower end of the wiring jig is fitted into the holes and fastened with bolts on both the top and the bottom surfaces of the perforated board. The board mounted with the wiring jig becomes the exclusive article for assembling the particular kind of wire harness.
On the other hand, since the wire harnesses follow a trend of diverse/small batch production and require assembling for test production, a wiring board which allows common use for assembly of different kinds of wire harnesses is highly desirable.
Therefore, a perforated panel in which a number of jig mounting holes are made in a matrix form has conventionally been used for a base board, and a wiring board of general configuration with wiring jigs in predetermined holes of the perforated panel has been proposed (for example, see Japanese Unexamined Utility Model Publication No. (Hei 5-69823).
This general-use type wiring board allows a wiring jig to be mounted on the top surface, but the mounting position of wiring jigs is determined by the mounting hole position that is preliminarily formed. Thus, it can be impossible to arrange the wiring jigs in the desired position on the perforated panel.
In addition, although it is considered that the mounting position can be adjusted after mounting the wiring jigs by adopting a mounting hole with an elliptical shape on the perforated panel, fastening with bolts from the top and bottom surfaces of the perforated panel is necessary in this case, thus requiring additional time and labor for mounting the wiring jigs.
Therefore, an object of the present invention is to provide a wire harness assembly jig capable of being easily fitted and removed, and which can be arranged at any position on the top surface of the perforated panel, and also to provide a perforated panel fixture for supporting this assembly.
SUMMARY OF THE INVENTION
According to a first aspect of the invention there is provided a fixture for fastening a wire harness assembling jig on a perforated panel in which multiple holes are formed and arranged with a predetermined spacing. The fixture includes a supporting member for supporting an assembly jig and a pressing mechanism for securing the supporting member onto the perforated panel. The pressing mechanism includes a pressing member having a pair of feet for positioning the pressing mechanism on one side of the panel by interfitting with two mounting holes in close proximity to each other. By the present invention, since the feet of the pressing member are fastened respectively to two mounting holes, the mounting strength of the assembly jig is high.
According to another aspect of the present invention, the pair of feet penetrate through each hole in the perforated panel and are provided with protrusions for engaging with the other side of the perforated panel. In this way, operation of the pressing mechanism from the top surface of the perforated panel can mount and remove the assembly jig.
In another aspect of the present invention, the supporting member includes a pillar supporting area which interfits with a pillar and a bench board arranged on the perforated panel. The pressing member has a transverse portion which spans the bench board and is provided at opposite ends with the pair of feet, and a pressing screw is provided on the transverse portion for pressing against the bench board. As a result, the assembly jig can be mounted at any desired position without restriction to the position of holes pre-formed with predetermined spacing in the perforated panel.
In a further aspect of the present invention, after mounting the assembly jig, a mere adjustment of the pressing screw allows the mounted position of the assembly jig to be easily changed. Furthermore, mounting and removing the assembly jig from the top surface of the perforated panel, as well as arranging it onto any position, can be implemented from one side of the perforated panel.
According to another aspect of the invention, there is provided an assembly jig for assembling wire harnesses with the assembly jig being fastened on a perforated panel in which multiple holes are formed and arranged with a predetermined spacing. The jig includes predetermined parts for use of assembling, including a pillar having a pointed lower end which supports the parts from a lower end, a supporting member for supporting the pillar, and a pressing mechanism for pressing and fastening the supporting member onto the perforated panel. The pressing mechanism includes a pressing member having a pair of feet for positioning the pressing mechanism from one side of the panel by interfitting with two mounting holes in close proximity to each other.
In a preferred embodiment of the invention, bracket assembly is provided for mounting a wiring harness jig on a base panel, and the wiring jig is provided with a cable receiving area which receives cables. A crank-shaped supporting member supports a pillar which supports the cable receiving area. The supporting member is fastened to a perforated panel by tightening a pressing screw of a pressing member having a pair of feet mounted in adjacent holes of the panel. Loosening the pressing screw allows the supporting member to rotate and also to slide so that the pillar can be installed at any desired position without being restricted by the position of the holes and are pre-formed with predetermined spacing in the perforated panel.
The pressing member includes a transverse bridge portion connecting the feet, with the bridge portion being spaced above the upper surface of the panel and mounting a clamping member, and the supporting member includes a base portion located under the bridge portion between the feet and engaged by the clamping member for securing the supporting member.
The support member may include a locating portion that receives a pillar of the wire harness jig, with the locating portion and the base portion being arranged at opposite ends of a connection portion, whereby in use, the locating portion is spaced from the upper surface of the panel. The pillar may include a pointed lower end that positions the pillar on the panel. Additionally, the locating portion may include a hole in which the pillar is received and fixed intermediate its ends, and the base portion and the locating portion may extend parallel to each other in opposite directions from opposite ends of the connection portion.
According to a further aspect of the invention, the combination of the bracket assembly with a perforated panel formed with a plurality of holes having a predetermined spacing for receiving the feet of the pressing member is provided. The holes in the panel may be aligned in two directions at right angles to each other, and the holes may be uniformly spaced apart in each direction or the spacing of the holes in one direction is different to that in the other direction.
