Description

[Detailed Description of the Invention] The present invention relates to a light bulb mounting device for an automobile lamp.

Various mounting devices (structures) of this kind have been proposed in the past, but each has its own merits and demerits, and none of them is completely satisfactory in terms of manufacturing, cost, and use. To provide a light bulb mounting device that is easy to replace and can prevent damage to a light bulb cord and short circuit without adding any special parts.

Below, an example of implementing the present invention will be explained based on the drawings.
is a reflector formed by press-molding a metal plate, and a support plate 4 for supporting a light bulb 3 is removably engaged with the center edge 2 of the reflector, and is pressed and supported by a set spring 5.

A set plate 9 having an approximately V-shaped cross section is spot welded to the center edge 2 of the reflector 1, and a light bulb 3 is placed in the concave portion 10 of this set plate 9.
The support plate 4 is removably inserted and engaged.

At this time, in order to avoid mounting the light bulb 3 on the set plate 9 and the support plate 4 in the wrong direction, the uneven portions 11a having different shapes are used.
, llb.

The support plate 4 is integrally fixed to the socket 12 of the light bulb 3.
A set plate 9 is attached to the center edge 2 of the reflecting mirror 1.
The set spring 5 is inserted into and engaged with the recessed part 10 of the set spring 5.
The mirror 1 is supported by pressure and is detachably attached to the reflecting mirror 1.

The set spring 5 is formed by bending an elastic metal wire, and its bent part 5a is swingably connected to the central rim 2 of the reflecting mirror 1, specifically, to the hook part 13 of the set plate 9. 5
One side 5b of b and 5c is freely hooked onto a hook-shaped hook 6 formed on the center edge 2 of the reflecting mirror 1, and the support plate 4 of the light bulb 3 is attached.
is pressed and supported on the center edge 2 of the reflecting mirror 1.

The leg portions 5b and 5c of the set spring 5 are extended parallel to the bent portion 5a, and the portions 5'b and 5'c of both leg portions 5b and 5c that face the support plate 4 are curved toward the support plate 4, and the other leg portions 5b and 5c are bent toward the support plate 4. The leg portion 5c is cut off at this portion 5'c, and one of the leg portions 5b is further extended so that it can be freely hung on the hook-shaped hook portion 6 on the set plate 9. At the same time, the end portion 5''b is bent up and further bent into a flat shape to form the clamp 7 which also serves as an operation section.

That is, one leg 5b has an end 5''b at the tip end thereof, which is hooked to the hook-shaped hook 6, bent at right angles to the reflecting mirror 1 and the reflective force, and further shaped into a square or circular shape when viewed from the front. The clamp 7 which also serves as an operation part is formed by bending the shape into a flat shape.

Incidentally, the end 7' of the clamp 7 which also serves as an operating section is curved so as not to damage the cord 8 when the cord 8 is attached or detached.

The clamp 7 which also serves as an operation part bends the end 5''b of one leg 5b of the set spring 5 into a flat shape so that it can be easily pressed and operated with the pad of a finger, and corresponds to the end of the one leg 5b. An opening 14 into which the cord 8 is inserted is formed at the end 7'.

Note that 15 in the figure is a ground terminal.

Since the present invention is configured in this manner, it has the following effects.

■ The support plate that supports the light bulb can be attached to and detached from the set plate by simply pressing the clamp that also serves as the operating part of the set spring with the pad of your finger and detaching one leg from the hook-shaped latching part of the set plate. Therefore, the work of setting and replacing light bulbs can be done easily and quickly.

■ The clamp that also serves as the operating part of the set spring is formed by bending the end of one leg and then folding it into a flat shape, so it makes good contact with the pads of your fingers, so you don't have to worry about damaging your fingers when setting or replacing light bulbs. do not have.

■ Since the set plate and the support plate that supports the light bulb are provided with uneven parts of different shapes that engage with each other, there is no risk of the support plate, that is, the light bulb, turning inadvertently, and it also prevents the filament of the light bulb from being oriented incorrectly. (reverse mounting)
There is no fear at all, and even if the spring force of the set spring becomes weak, there is no need to worry about the support plate accidentally falling off from the set plate.

■ Since the light bulb cord can be engaged and held in the clamp that also serves as the operating part of the set spring, it is possible to prevent the cord from being damaged or short-circuited, and no special parts are required to hold the light bulb cord. , easy to manufacture and assemble, and can be provided at low cost.

■ The end of the set spring that makes up the clamp that also serves as the operating section is curved outward, further eliminating the risk of damaging the cord.

■ Since the cord insertion port is provided in the clamp that also serves as the operating section, the cord of the light bulb can be freely and easily connected to and removed from the clamp that also serves as the operating section.

■ The light bulb cord is engaged and held in the clamp that also serves as the operation unit, so when replacing the light bulb, if you remove the set spring from the hook-shaped hook on the set plate, the light bulb cord will rise with the set spring (see Figure 2). (state shown by imaginary line),
The light bulb cord does not get in the way, making it easier to replace the light bulb.

Therefore, the intended purpose can be achieved.
