Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a mounting structure between a housing and a socket holder in a vehicle lamp such as an automobile.

(Prior Art) This type of mounting structure between a housing and a socket holder is known as shown in FIGS. 6 to 8.
In this known structure, 1 is a housing, and a socket holder mounting hole 2 is provided in the housing.
is provided, and the mounting hole 2 has a plurality of notches 3, 4.
is provided. The socket holder 5 attached to this housing has a pair of wings 6 along the length direction on its body, and an attachment side end,
That is, an insertion portion 7 and a flange portion 8 are provided on the front end side, and claw portions 9 and 10 are formed on the insertion portion 7 in correspondence with the notches 3 and 4. Ribs 11 and 12 are provided at the center, respectively.

When assembling the housing 1 and socket holder 5 having such a configuration, first install the socket 13 into the socket holder 5, install the light bulb 14 into the socket, and then insert the housing 1 with the light bulb side first. The insertion part 7 is inserted into the attachment hole 2. At this time, the socket holder 5 is pushed in with the claws 9 and 10 corresponding to the notches 3 and 4. When pushed in in this manner, the flange portion 8 comes into contact with the outside of the housing 1, and the claw portions 9 and 10 come to face the inside of the housing 1. In this state, if you turn the socket holder, for example, to the right, the ribs 11 of the claws 9, 10,
12 comes into contact with the inside of the housing 1, moves over the notches 3 and 4 while rubbing against the housing, and the ribs 11 and 1 of the flange part 8 and the claw parts 9 and 10
It can be installed by holding the housing between 2 and 2.

However, with such a mounting structure,
When the socket holder 5 is attached or removed, the ribs 11, 12 rub against the housing 1, so the ribs 11, 12 are significantly worn down, and if the socket holder 5 is continued to be used, the clamping pressure will decrease. There is a backlash between the two, and there is a tendency for the socket holder to loosen due to the transmission of vibrations and fall off, making it unusable for a long period of time.

(Purpose of the invention) The invention was made in order to eliminate these drawbacks, and its purpose is to reduce the wear and tear of the ribs by half when attaching the socket holder to the housing, so that it can be used for a long time. Rather, the present invention aims to provide a mounting structure between the housing and the socket holder, which allows the mounting operation to be performed with a single touch.

(Structure of the invention) The present invention, which has been made to achieve the above object, has a housing provided with a mounting hole having a plurality of notches, an insertion part and a flange part on the front end side, and an insertion part and a flange part. and a socket holder provided with a claw portion corresponding to the cutout portion, and the housing is held between the flange portion and the claw portion, the socket holder having the cutout portion along the mounting hole on the housing side A plurality of chamfered portions are provided at positions shifted by an appropriate angular range from A housing and socket holder mounting structure characterized by having elasticity and providing alignment marks on the housing and the flange portion for positioning during press-fit mounting, We have added elasticity to the part where the claw part is formed, so just by aligning the alignment marks and pressing, the claw part will go beyond the chamfer and be located inside the housing, and will be clamped between it and the flange part. The socket holder can be installed with one touch, and the wear of the ribs provided on the claws is halved, allowing for long-term use.

(Examples) Next, the present invention will be explained in more detail with reference to illustrated examples. In order to facilitate understanding, the same parts as in the conventional example are given the same reference numerals and the explanation thereof will be simplified.
The mounting hole 2 of the housing 1 has a plurality of notches 3,
4, a plurality of chamfered parts 21 and 22 are provided along the mounting hole at positions shifted by an appropriate angle range (approximately 30 to 60 degrees) from the notch, and one surface of the chamfered parts is provided. An alignment mark 23 is provided on the housing 1 to indicate the position of the handle 21. In addition, the other notch 4 of the notches is formed by cutting out the angle range (approximately 30 to 60 degrees) more than the conventional notch, and serves to prevent rotation in the opposite direction as described later. fulfill.

The socket holder 5 is the same as the conventional example in that it includes a wing portion 6, an insertion portion 7, a flange portion 8, claw portions 9, 10, and ribs 11, 12, but it is further modified according to the present invention. As shown in FIGS. 3 and 4, the insertion portion 7 has slits 24, 25,
The feature is that 26 and 27 are provided. In this case, the slits are formed close to both sides of each claw portion 9, 10, so that the portion where the claw portions are formed has elasticity as a whole. Furthermore, a stopper protrusion 28 that fits into the notch 4 is integrally formed in the insertion part 7 in the vicinity of the other claw part 10. It is possible to move up to the end, thereby determining the direction of rotation of the socket holder 5.

Alignment mark 23 on the housing 1 side described above
Correspondingly, similar alignment marks 29 are provided on the socket holder 5 side as well. In this case, since the mark 23 on the housing side is provided at a position to indicate the position of the chamfered portion 21, the corresponding position on the socket holder 5 side is also provided to indicate the position of one of the claw portions 9. and is provided on the flange portion 8. These alignment marks 23,
29 does not necessarily need to indicate the positions of the chamfers and claws, and alignment marks may be provided in other parts so that the corresponding chamfers and claws match.

(Function) In the mounting structure of the present invention configured as described above, the socket 13 is inserted and fixed in the socket holder 5 in the same way as in the conventional example, and after the light bulb is attached to the socket 13, the fifth light bulb is attached. As shown in the figure, align the alignment marks 23 and 29 and place the socket holder 5 facing the mounting hole 2 of the housing 1, and then press the socket holder 5 further, so that the claws 9 and 10 align with the corresponding surface. Abuts against the handles 21 and 22,
The entire claw forming part divided by the claw and the slit along the chamfer is pushed inward, and when the claw exceeds the thick part of the housing, it restores itself by its own elastic force, and the housing 1 is It comes to be held between the claw part and the flange part 8. Therefore, when attaching the socket holder 5, it can be easily attached by simply pressing the rib 1.
1 and 12 will not rub against the housing 1. When the socket holder 5 is installed in this state, the stopper protrusion 2 provided on the insertion part 7
8 is located near the lower end of the notch 4 in the drawing.

The socket holder 5 may be damaged due to a disconnection of the light bulb 14, etc.
When removing the socket holder 5, rotate the socket holder 5 to the left by a predetermined angle, for example, about 60 degrees, as in the conventional example, so that the claw part 9 is located in the notch part 3, and the claw part 10 is in the notch part 4. It can be located and removed. At this time, the stopper protrusion 28 fitted in the notch 4 moves toward the upper end of the notch 4 in the drawing and comes into contact with the end of the notch, making it unable to rotate any further. If you accidentally try to remove the socket holder 5 by rotating it clockwise, the stopper projection 28 will be in contact with the lower end of the notch 4, making it impossible to rotate it clockwise. , it is impossible to make a mistake from the beginning.

(Effects of the invention) As explained above, the mounting structure of the housing and socket holder according to the present invention is such that the housing is held between the flange part and the claw part of the conventional example, and the structure is such that the housing is held between the flange part and the claw part of the conventional example, and the mounting structure is such that the housing is held between the flange part and the claw part of the conventional example. We improved the structure in which the housing and the ribs of the claw part rub against each other when rotated, and provided multiple chamfers on the housing side, and provided slits close to both sides of the claw part on the socket holder side. The structure has alignment marks, so it can be easily installed with one touch by simply pressing.
Since the ribs of the claw part and the housing only rub against each other when they are removed, the degree of abrasion of the ribs is halved compared to the conventional one, and the service life is doubled, which is an excellent effect.

Furthermore, the installation process is extremely simple since it requires only one-touch operation of pressing as described above, and it also has the excellent effect of being able to be quickly installed in the correct position using the alignment marks. .
