Description

  The present invention relates to an electrical component mounting structure, and more particularly to an electrical component mounting structure that has wiring and needs to be mounted in a state of being exposed or semi-exposed on the surface of a vehicle interior.

  When mounting a part such as an electrical component in a vehicle, in order to firmly fix this part to the mounting counterpart part, use a plurality of screws as fixtures and tighten these screws to attach the part to the mounting counterpart part. It is fixed to.

Japanese Patent No. 40621136 JP-A-10-108337 The vehicle antenna attaching / detaching structure according to Japanese Patent Application Laid-Open No. 57-104006 includes a pawl portion formed in the first bracket and a hole portion formed in the second bracket. By hooking the claw part into the hole of the second bracket, the second bracket is attached to the first bracket, the antenna body is attached to the second bracket to constitute the antenna assembly, and the first bracket is After attaching to an instrument panel, the nail | claw part of a 1st bracket is hooked in the hole part of a 2nd bracket. In the mounting structure of the electric junction box according to Patent Document 2, an appropriate number of claw portions as one of the hook portions and a fastening tongue piece as one of the fastening portions are provided on the box body, and the panel is provided with the claw portion. A hooking piece as the other of the hooking parts to be engaged, a claw part, and a fastening plate as the other of the fastening part are provided, and when the hooking part is hooked on the hooking piece, a fastening tongue piece and a fastening plate, A shift amount is interposed between the two. The component mounting structure according to Patent Document 3 is provided with a locking claw or a locking portion that can be engaged with an engaging portion or a locking claw of a mounting panel and a screw insertion hole on the joint surface of the mounting component. In the vicinity of the insertion hole, a cover having an opening is provided on the surface of the locking claw in the engagement slide direction, and an opening into which the cover can be inserted is provided on the mounting panel.

By the way, conventionally, when fastening a screw and fixing a part, if only one screw is tightened, if only one part of one part of the part is tightened with a screw, it cannot be firmly fixed to the mounting counterpart part. There is a risk of rattling or the like, and when multiple screws are tightened, the number of screws increases, which increases costs and increases the number of mounting steps due to multiple tightening locations. There was an inconvenience.
In addition, when mounting electrical components around the instrument panel as a vehicle interior, consideration is given to securing and storing a dedicated mounting space for relatively large AV devices such as navigation systems, audio, and speakers. However, there are still few structures in consideration of attachment about the fixtures accompanying them, ie, small electrical components, such as an antenna.
And not only AV devices but also communication devices using radio waves such as ETC are steadily increasing, and accordingly, small electrical components such as antennas are also increasing.
However, since many electrical components are interchangeable as after-parts, small electrical components such as antennas that accompany them can be easily fixed using double-sided adhesive tape or strong magnets, even if a bracket is interposed. Is the mainstream. Moreover, as a place to be disposed, the instrument panel is often provided so as to be as inconspicuous as possible in a dead space that is close to the glass that transmits radio waves and is far from the occupant on the upper surface of the instrument panel.
However, when such an electrical component is mounted as a standard equipment, it is required to have a good appearance as a product, stable quality over a long period of time, and ease of assembly in a factory. In the case of such an electrical component, considering the versatility of the mounting method, the wiring extraction direction is extended along the mounting surface of the electrical component (or the mounting surface of the plate-shaped bracket). Therefore, it is necessary to consider the processing of wiring.
Furthermore, the above-mentioned Patent Document 1 is complicated and large in size, high in cost, and unsuitable for deployment in a small vehicle. Further, in Patent Documents 2 and 3 described above, mounting methods by hooking and fixing (bolts and clips) are disclosed, but wiring of electrical components is not considered.

  Accordingly, the object of the present invention is to provide an electrical component mounting structure that can be mounted with good appearance, mounted so that the wiring is not improperly sandwiched, and can stably support and fix the electrical component over a long period of time. It is to provide.

  According to the present invention, an electrical component having wiring is supported in a proper position in the vehicle interior through a base bracket having a hook portion and a fixed portion provided corresponding to the hook portion and the fixed portion provided in a proper position in the vehicle interior, respectively. In the mounting structure of the electrical component to be fixed, an insertion hole of the hooking portion provided continuously to the hooked portion and a wiring opening through which the wiring of the electrical component passes are provided as a continuous opening portion, and the insertion of the opening portion is performed. A portion excluding a part of the hole is shielded by the base bracket fixed to the electrical component.

  According to the mounting structure of the electrical component of the present invention, the base bracket to which the electrical component is fixed is attached to the vehicle interior by being hooked and fixed, so that the electrical component having the wiring is mounted with a good appearance and the wiring is not improperly sandwiched. In addition, the electrical component can be supported and fixed stably over a long period of time.
