Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a component fixing structure for attaching various components to a panel.

[Prior Art] Conventionally, a connector as shown in FIG. 4 has been known as a connector for connecting and fixing various parts to a panel. This connector has a screw insertion hole b formed in a flange body a, and two legs c, c that are integrally protruded from the outer periphery of the lower end of the insertion hole B, facing each other at a predetermined distance. The legs c, c are made of plastic, and each of the legs c, c has a proximal end portion (a portion connected to the flange member a) having a thickness that is almost the same as that of the other portions.

To use this connector, insert the above-mentioned legs c and c into the mounting square holes e of panel d while bending them inward, and after inserting the legs c and c from the outside. When the pressing force is released, the legs c and c are elastically returned to their original states, and the panel d is brought into contact with the lower surface of the flange body a supported at the proximal ends of the legs c and c, and this state is maintained. Then pass the shaft of the screw sequentially through the mounting hole g of the mounted part f and the insertion hole b of the flange body a, and then attach the two leg bodies c and c.
By inserting the screw between them and rotating the screw, the screw shaft can be screwed into the inner surfaces of both legs c and c using the threaded part formed on the outer periphery of the screw shaft. The legs c and c are extended between the legs c and c, and the lower parts of the legs c and c are expanded outward, respectively, and the panel d
is pressed and fixed to the connecting tool, and the above-mentioned mounted part f is connected and fixed to the panel d.

[Problems to be solved by the invention] However, in the case of the component mounting structure using the above-mentioned coupling tool, especially the flange body a of the coupling tool is
If it is thick, it will be difficult for the legs c, c to bend inward, and unless a considerable pressure is applied from the outside, these legs c, c
There is a problem in that it is difficult to insert the panel into the hole e of the panel d. In particular, since the insertion of the legs c, c into the holes e is usually done manually, if the insertion force is high, the work is difficult and the work efficiency is reduced.

In addition, especially when using a plurality of the above-mentioned connectors and connecting and fixing the attached part f to the panel d at multiple places, when connecting and fixing one place and then connecting and fixing the other places, the attached part There are cases where the hole g of f and the hole b of the connector do not match well, making positioning difficult.

The present invention was made to improve the above-mentioned situation, and it is possible to easily insert both legs into the square mounting hole with a relatively small force, and it is also possible to securely screw the screw between both legs. The screw tightening force can be reliably exerted by
Another object of the present invention is to provide a component mounting structure using a connecting tool that allows reliable and easy positioning even when the mounted component is connected and fixed to a panel at a plurality of locations.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a screw insertion hole bored in the flange body, and a screw insertion hole that faces each other at a predetermined distance from each other on the outer peripheral edge of the lower end of the insertion hole. Using a connector with two protruding legs, insert the legs of this connector into the rectangular mounting hole of the panel to bring the panel into contact with the lower surface of the flange body, and Arranging the part to be attached on the upper surface, inserting the shaft part of the screw between the legs through the through hole formed in the part to be attached and the screw insertion hole, and rotating the screw,
The threaded portion formed on the outer periphery of the screw shaft is threaded into the inner surface of both legs, and the screw shaft is advanced between these two legs, so that the lower part of the screw shaft extends outward. The connecting tool is fixed to the panel by pressing the square mounting hole of the panel with the spread legs, and the part to be installed is held between the head of the screw and the flange of the connecting tool, and the part to be installed is fixed. In the component mounting structure for attaching the component to the panel, the through-hole forming portion of the mounted component is a protrusion that protrudes outward, and
A recess corresponding to the protrusion is formed on the upper surface of the flange body of the connector so that the protrusion and the recess are fitted together, and a cutout groove is formed on the inner surface of the proximal end of both legs of the connector. To provide a component mounting structure characterized in that a thin wall portion is formed at the base end portions of both legs, and a locking protrusion for preventing rotation that projects inward is provided.

In this case, the connecting tool is provided with a thin walled portion with a cutout groove formed on the inner surface of one end in the width direction of the proximal end of one leg, and a locking protrusion protruding from the other end,
A locking protrusion is provided protruding from one end in the width direction of the proximal end of the other leg, and a thin wall portion formed by a notch groove is formed on the other end side, so that the thin wall portion of one leg and the locking projection are connected to the other leg. It is preferable that the locking protrusion and the thin wall portion of the leg body are provided so as to face each other.

[Function] According to the component mounting structure of the present invention, the notch grooves are formed on the inner surface of the base end portions of both legs of the connector, and the thin wall portions are formed on the base ends of both legs, so that the external When the legs are pressed from the opposite direction, the thin parts of the legs easily bend inward, and the legs can be elastically deformed inward with a small pressing force, making it easy to attach the legs to the panel. It can be easily inserted into a square hole, and even when such an insertion operation is performed manually, only a small insertion force is required, which facilitates the operation and improves work efficiency.

In this case, according to the inventor's study, if the entire base end of both legs is made thin, inward flexibility will be improved; When tightening the screw, that is, when rotating the screw and screwing the screw shaft between the legs to form a threaded part on the inner surface of both legs with the screw shaft, use the square mounting hole on the outside of the base end of both legs. The locking force to the circumferential surface is weak, and the threaded part of the screw shaft easily bends inward due to the thread forming force (engraving force) when screwing the threaded part into the inner surface of both legs, and the screw Co-rotation, in which the connector rotates together with the rotation of the screw, often occurs, making it impossible to tighten the screw. However, according to the connector constituting the mounting structure of the present invention, since locking protrusions for preventing rotation protruding inward are provided on the inner surfaces of the proximal ends of both legs, the above-mentioned thread forming force (engraving force) is provided. ) acts on both legs, the outer surface of the locking protrusion strongly contacts and presses the inner peripheral surface of the square mounting hole, so the rotation of both legs is reliably locked by the locking protrusion. As a result, the joints do not rotate together, so that the screw portions can be reliably screwed into the inner surfaces of both legs, and the screw shaft portion can be screwed into the screw portions, so that the screws can be tightened reliably.

Further, in the mounting structure of the present invention, the through-hole forming portion of the mounted component is formed as a protrusion that protrudes outward, and a recess corresponding to the protrusion is formed on the upper surface side of the flange body of the connector, Since these protrusions and recesses are configured to fit together, even when connecting and fixing the mounted parts to the panel at multiple locations, the screw insertion hole of the connector temporarily fixed to the panel and the through-hole of the mounted part The parts can be reliably and easily aligned and positioned, and the parts to be mounted can be reliably connected and fixed to the panel at a plurality of locations.
