Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a frame type component holder for holding a harness component such as a connector provided in a wire bundle such as a wire harness.
[0002]
[Prior art]
Generally, a wire bundle such as a wire harness is an electrical wiring system that constitutes a predetermined circuit by connecting a plurality of wires and a harness component such as a connector.
[0003]
When manufacturing such a wire harness, a holder for receiving the electric wire is provided on a drawing board called an assembly drawing board, and the electric wire constituting the wire harness is laid on the holder, and necessary exterior parts are attached. ing.
[0004]
By the way, in recent years, it has been required to minimize the tolerance in the finished dimensions of the wire harness. Therefore, recently, a frame-type component holder called a box jig is provided on the assembly drawing board. This frame-type component holder has a resin product that surrounds a harness component to be held along its outline, and the harness component is mounted in a housing space formed in the resin product. It is designed to be positioned precisely. And conventionally, the dimensional accuracy of the wire harness was kept high using such a frame type component holder.
[0005]
However, along with the demand for computerization of vehicles and the production of a variety of products in small quantities, the number of harness components used for wire harnesses has become very diverse.
[0006]
For this reason, the higher the dimensional accuracy, the greater the versatility of the frame-type component holder and the number of types.
[0007]
In particular, at the stage of producing a wire harness, a holder for receiving an electric wire is provided on a drawing board called an examination drawing board, and the electric wire constituting the wire harness is laid on the holder, and necessary exterior parts are attached. However, since the specification change is frequently repeated on the study drawing board, it is necessary to quickly prepare a wide variety of frame-type component holders.
[0008]
In order to solve such a problem, a general-purpose frame-type component holder has been developed to some extent. For example, Japanese Patent Laid-Open No. 10-106368 discloses a technique of a frame-type component holder corresponding to various connectors having different shapes depending on a structure in which a side surface of a connector is sandwiched as a harness component.
[0009]
[Problems to be solved by the invention]
However, in the prior art disclosed in the above publication, since the side surface of the connector is only sandwiched between two parallel members, it is difficult to maintain the dimensional accuracy of a connector having a complicated shape like a so-called box jig. Met. Even if the shape is simple, it is still difficult to maintain the posture of the connector when the two surfaces of the frame-type component holder that sandwich the connector are narrow, and the recently required dimensional accuracy is maintained. I couldn't. Further, in the conventional drawing board, since the dimensional accuracy is merely ensured only by the position restriction of the connector, the position restriction regarding other harness parts is not taken into consideration.
[0010]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and is a frame-type component holder that can maintain both high dimensional accuracy and versatility in a drawing board related to a wire harness such as an assembly drawing board or a study drawing board.
