ABSTRACT:

SUMMARY OF THE INVENTION
Average miniature light bulb sets mainly comprise a miniature light bulb seated in a socket that is composed of a holding element and a shell element. The holding element of a prior art socket structure is provided with a receiving portion and an insertion portion; the receiving portion accommodating a light bulb and the insertion portion being housed in the shell element. Both portions have fixed shapes. If the size of the receiving portion is too large, the holding element can not firmly secure a light bulb. On the other hand, if the size of the receiving portion is too small, it is hard to insert a light bulb. Besides, such structure needs more material to build and so it affects product weight. Thus it is not cost effective.
In view of these problems, the object of the invention is to provide a simplified miniature light bulb socket structure that makes use of a specially designed holding element in conjunction with a shell element to provide a better grasping effect while the structural material is reduced. Now the features and advantages of the invention will be enumerated with reference to the accompanying drawings.
