Description

[Detailed description of the invention] The present invention relates to the structure of a support part of a vibration-resistant incandescent light bulb, in particular, which supports a light emitting body by bending the tip of the support. The purpose is to improve vibration resistance by preventing wire breakage.

Normally, the structure of this type of light emitter support part is as shown in Fig. 1, where the flat part of the support S is folded in half, and the flat part of the support S has the same thickness at the tip. The end of the light emitting body f is inserted into this, and in this state, the light emitting body is crushed and fixed from both outer surfaces so as to be sandwiched therebetween.

However, when this type of crush fixation is performed,
Since the thickness of the flat part is uniform, more force than necessary is applied to the inner side of the support S at point a, resulting in excessive caulking, which causes mechanical distortion due to direct vibration due to the weight of the light emitter f. wire breakage is likely to occur,
Moreover, if the wire is broken, the outer point b side will not play any role and will lose its existence value.

The present invention aims to eliminate the above-mentioned drawbacks as much as possible, and the configuration of a specific embodiment thereof will be described in detail with reference to FIG. 2 and subsequent figures.

Figure 2B is an enlarged front view of the flat end of the support S, and as seen in Figure 2A, which is a cross-sectional view taken along the It is thin and thick on the outer side b as shown in t, and is formed so that the inner surface is inclined with respect to the outer surface.

The present invention has the above-mentioned configuration.Next, the operation and effect will be described with reference to FIG. 3 showing an enlarged plan view of the pinched part. Because it is formed so that it is inclined at an angle, even if it is crushed and fixed with a constant pressure, the inner side will be weaker and the outer side will be stronger due to the difference in wall thickness.
As a result, the inner side prevents excessive crimping and maintains a good clamping force, while the outer side prevents the light emitter f from coming off, and also controls the crimping pressure. It has excellent effects, such as being easy to use and easy to use, to fully achieve the intended purpose stated at the beginning of this section.
