[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a harness mounting structure in a resin shroud designed to prevent a motor harness from coming off.

[0002]

[Prior Art]

 In order to forcibly cool the cooling water guided to the radiator, conventionally, a motor is fixed to the rear of the radiator via a shroud, and this motor rotates a motor fan mounted on the rotary shaft to generate cooling air. It is designed to blow air to the radiator.

The shroud is often made of metal because of its strength problem. However, due to the recent advances in composite materials made of synthetic resin, a resin as disclosed in Japanese Utility Model Laid-Open No. 63-96228. Shrouds have been widely used, and the use of such resin shrouds has made it possible to reduce the weight and cost of the shroud.

Thus, conventionally, in this type of resin shroud, as shown in FIGS. 4 to 6, a motor fan mounting stay (hereinafter referred to as “stay”) in which the motor supporting portion 1 is molded is formed. 3, two locking claws 5 projecting to the engine side are provided so as to closely face each other, and the motor harness 7 is locked between the two locking claws 5 to attach the harness 7 to the stay 3. I was wiring along.

[0005]

[Problems to be solved by the device]

 However, as shown in FIG. 6, the locking claws 5 are successively formed to be thicker toward the front ends thereof, so that the intervals between the front ends of both the locking claws 5 are narrowed and the locking claws 5 are arranged inside the locking claws 5. Although the structure is such that the distance between the protruding claw portions 5a is narrower than the diameter of the harness 7, the portion (the portion A in the figure) extending from the relevant claw portion 5a to the inside of the locking claw 5 is respectively. Since the harness 7 has a gentle curved surface with a curvature larger than that of the outer shape of the harness 7, there is a possibility that the harness 7 may come off from between the claw portions 5a due to vibration during traveling of the vehicle.

When the harness 7 is pulled out from between the locking claws 5 in this way, the harness 7 is broken due to vibration, and the cooling air blown to the radiator collides with the harness 7 to generate wind noise. There were drawbacks such as.

The present invention has been devised in view of such an actual situation, and is a resin shroud for fixing a harness through a locking claw provided on a stay, and a resin shroud for preventing the harness from coming off. An object is to provide a harness mounting structure.

[0008]

[Means for Solving the Problems]

 In order to achieve such an object, the harness mounting structure in the resin shroud according to the present invention is a harness for a motor that drives a motor fan in a stay where the motor fan is arranged in the motor fan opening of the shroud body. The two locking claws for locking are provided so as to face each other, and a folding back stop portion is provided at the tip of each locking claw.

[0009]

[Action]

 According to the present invention, even if the harness tries to come out of the locking claw due to vibration during traveling of the vehicle, the folded back claw portion bites into the outer cover of the harness to prevent the harness from coming off.

[0010]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 9 denotes a stay. The stay 9 is formed with a motor support portion 11 for arranging a motor fan in a motor fan opening 10 of a shroud body, and a reinforcing piece protruding toward the engine side. 9a and 9b are integrally formed along both side edges of the stay 9, and a plurality of ribs 9c are formed between the reinforcing pieces 9a and 9b.

Thus, in this embodiment, as shown in FIGS. 1 and 2, the reinforcing pieces 9a and 9b corresponding to the width m between the two ribs 9c located substantially in the center of the stay 9 are formed. The portion is made to function as a locking claw 11 for locking the harness 7 of the motor for driving the motor fan, and the tip of the locking claw 11 (reinforcing pieces 9a, 9b) has a cross section of FIG. As shown in the drawing, the folded back clasps 13 which are folded back inwardly and have a sharp tip are provided over the width m, and the distance n between the folded clasps 13 is made smaller than the diameter of the harness 7. It is characterized by being provided by.

In addition, in FIG. 1, 15 is a die-cutting hole formed between the ribs 9c, 17 is a mounting portion of the motor, and 19 is a reinforcing protrusion provided in the vertical direction of the locking claw 11. When the resin shroud according to the embodiment is integrally molded, the mold is removed from the mold removal hole 15 to form the folded back blocking portion 13.

Since the mounting structure of the harness in the resin shroud according to the present embodiment is configured as described above, the motor having the motor fan attached to the rotating shaft is mounted on the motor supporting portion 11, and The harness 7 of the motor may be wired along the stay 9, and the harness 7 may be press-fitted and locked between the folded back bite portions 13 as shown in FIG.

Further, even if the harness 7 tries to come out of the locking claw 11 due to vibration during traveling of the vehicle, the tip of the folded back clasp 13 bites into the outer cover of the harness 7 to prevent the harness 7 from coming off. According to this embodiment, as compared with the locking claws 5 in the conventional resin shroud shown in FIG. 4, there is an advantage that the harness 7 can be reliably prevented from coming off.

In the above embodiment, the locking claws 11 are formed by utilizing the reinforcing pieces 9a and 9b integrally formed along the both side edges of the stay 9, but the present invention is limited to such a structure. However, for example, as shown in FIG. 3, the locking claw 5 is provided with only the locking claw projecting from the stay 3, and the inner end of the locking claw is folded back inward as shown in FIG. It is also possible to provide the stop portion 13, and even with such a structure, the intended purpose can be achieved as in the above-described embodiment.

[0016]

[Effect of the device]

 As described above, according to the present invention, it is possible to more reliably prevent the harness from coming off, as compared with the related art.
