DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for facilitating the cutting of a wire harness arranged on a vehicle body, and more particularly to a structure for easily removing the wire harness when disassembling or repairing a vehicle.

[0002]

2. Description of the Related Art Recently, the necessity of separate disposal and recycling of discarded automobile parts and materials has been increasing, and it has been demanded that the automobile can be easily dismantled in order to increase their efficiency. In particular, batteries,
Not only air conditioners and radiators, but also wire harnesses that are routed on the car body, are removed from the car body to recycle electric wire conductors.

Conventionally, as shown in FIG. 7, the wire harness is removed by using a crane truck 1 and operating a gripping portion 3 of a crane 2 to grasp an arbitrary portion of the wire harness W / H. In this state, the gripping portion 3 is forcibly peeled off from the vehicle body by a traction force that pulls the grip portion 3 away from the vehicle body. Alternatively, there is a case where a hook is attached to the grip portion 3, the wire harness W / H is hooked with the hook, and the wire harness W / H is similarly pulled off by the pulling force of the crane.

[0004]

However, as shown in FIG. 8, the wire harness W / H includes an engine room 4, a vehicle room 5, a trunk room 6, left and right back doors 7, and the like.
Since the vehicle body panels 8a and 8b that separate each room become obstacles because they are routed in various places of the car, the wire harness W / H cannot be pulled out or is torn off in the middle.
It is very difficult to take out the entire wire harness W / H.

[0005] In connection with this, recently, it has been attempted to pull out the wire harness while cutting it using a small-sized hydraulic or electric cutter. Pulling out is difficult, and the fact that the wire harness is not fixed for cutting at the cutting point is an obstacle. In addition, it is often difficult to insert a cutter into the wiring harness wiring location in the first place, and it is presently difficult to cut the wire harness.

The present invention has been made in view of the above problems, and has as its object to make it easy to take out a wire harness when disassembling or repairing a vehicle body.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a method for mounting a wire from a position above a wire harness passing through the through hole on a side surface of a vehicle body panel having a through hole through which the wire harness passes. A cutting blade guide plate having a deep-angle hole with an upper surface opening is attached to a position below the harness, and the cutting blade guide plate is provided with a through hole communicating with the through hole of the vehicle body panel. A structure for facilitating the cutting of a wire harness routed to a vehicle body, wherein the wire harness is configured to be cut by lowering a cutting blade from an upper opening of a square hole.

[0008] According to the above configuration, since the wire harness is cut at the place where the vehicle body panel penetrates, the wire harness can be divided for each room partitioned by the vehicle body panel. Therefore, when the wire harness is taken out by the crane, the wire harness can be easily pulled out without the body panel being hindered or being torn off in the middle. Also, at the time of cutting, the through holes of the two plates of the vehicle body panel and the cutting blade guide plate communicating with the wire harness support the wire harness from below, so that the wire harness can be fixed on both sides at the pressing down position of the cutting blade. ,
The cutting operation can be performed efficiently and easily. further,
Since the wire harness is divided and collected for each room, the wire harness of one divided portion is shortened, and the collection rate is increased.

[0009] As the cutting blade, a so-called guillotine-shaped cutting blade or a cutting machine such as a chain saw that matches the dimension of the deep angle hole is used. Further, it is desirable that the shape and size of the deep angle hole be standardized by each car maker and each car model.

[0010] It is preferable that the position of the upper surface opening of the deep angle hole of the cutting blade guide plate is located immediately above the wire harness and at a position where there is no external interference material and the cutting blade can be inserted into the deep angle hole. .

By providing a deep-angled hole directly above the wire harness, the direction and position of the cutting blade can be guided stably, and the cutting blade comes into contact with the wire harness vertically.
The shearing force is the highest and cutting is easy, and the cutting operation is safe and accurate. Further, a deep angle hole is provided at an upper position where there is no external interference material so that a cutting operation can be performed by the cutting blade. At the stage of designing the wiring harness routing route,
It is preferable to consider the optimal cutting position of the wire harness.

A grommet is attached to a wire harness passing through the through hole of the vehicle body panel and the cutting blade guide plate, and a peripheral edge of the through hole of the vehicle body panel and the cutting blade guide plate is provided in a vehicle body locking groove provided on an outer periphery of the grommet. And the wire harness inside the body locking groove of the grommet and the inside thereof can be cut by the cutting blade.

Since the grommet is attached to the wire harness at the portion where the vehicle body panel through-hole passes, the grommet is cut at the same time as the wire harness as described above. Unlocking and removing the grommet from the through-hole in the vehicle body panel is troublesome, and the wire harness is often fixed via the grommet and the waterproofing agent. In addition, the wire harness can be efficiently removed from the vehicle body panel when dismantling the vehicle.

[0014] The cutting blade guide plate may have a shape in which a flange is projected from both sides of a concave cross section, and the flange is welded to a side surface of the vehicle body panel to form the deep angle hole between the cutting blade guide plate and the vehicle body panel. preferable. In this way, by making the cutting blade guide plate have a concave cross section, it is possible to position and guide not only the front and back but also the side surface of the cutting blade.

Preferably, the wire harness to be cut by the cutting blade is a main line, and display means is provided on the vehicle body panel side or the wire harness side at a position where the cutting blade guide plate is installed. By cutting the trunk line, branch lines branching off from the trunk line can be easily pulled together. Also, considering the ease and efficiency of the cutting work, it is possible to determine the optimum cutting position in advance, and by displaying the location, the dismantling contractor etc. need only cut the displayed location, The work of collecting the wire harness can be standardized, and the workability can be improved and the work time can be shortened. Regarding the lifting position with the crane, the position where the wire harness can be pulled out most efficiently is determined in advance and determined, and by displaying the position, the wire harness collection operation can be performed more efficiently.
