Description

[Detailed explanation of the idea] This invention relates to a holder for a light bulb.

There is a light bulb holder that is used by inserting a small light bulb and attaching it to a printed board, etc. For example, as shown in Figure 1, the holder body a is made of synthetic resin, and the side wall has locking holes. In addition, a flange C is provided at the lower end, and the lead wire e of the light bulb d inserted into the holder body a is pulled out from the bottom "JLf", and the lead wire e of the light bulb d inserted into the holder body a is pulled out from the groove g formed on the bottom of the flange C. Bend and insert each along the
Further, pull it out from the end of the groove g to the upper surface side of the flange C,
It has a structure in which the lead wire is hooked into a notch h provided on the edge of the flange C, guided to the bottom side again, and the tip of the lead wire is bent and fitted into a groove i formed on the bottom surface of the flange C.

When the holder main body a is inserted and locked into the mounting hole of the printed board j, the printed board j is held between the protrusion of the holder main body a and the flange C, and as mentioned above, the upper surface of the flange C The part of the lead wire pulled out to the side,
It is designed to be electrically connected by press-contacting the printed conductor (not shown) of the printed board j.

As mentioned above, this light bulb holder has the bulb lead wire exposed on the bottom of the holder body, which can cause a short circuit, and the hole for inserting the lead wire through, which can cause light leakage. Furthermore, since the groove is formed on the bottom surface of the holder body, there are various drawbacks such as a narrow plane space for displaying marks.

The present invention was made to eliminate these conventional drawbacks, and by attaching a cover to the bottom of the holder body,
The gist of this is a structure that prevents exposure of lead wires and light leakage.

Hereinafter, the present invention will be explained with reference to the illustrated embodiments. Reference numeral 1 denotes a holder body made of synthetic resin, a side wall of which is provided with locking protrusions 2, and a flange 3 provided at the lower end of the holder body. A groove 4 is formed in the circumferential direction.

Reference numeral 5 denotes a tray-shaped cover made of non-transparent synthetic resin, on the inside of the side wall, protrusions 6 that fit into the grooves 4 are formed in the circumferential direction, and the side walls are provided with appropriate intervals. Several notches 7 are provided at the openings.

This cover 5 can be fitted onto the flange 3 by fitting the convex strip 6 into the groove 4, and the lead wire of the light bulb 8 inserted into the holder body 1 can be attached to the bottom side of the flange 3 as in the conventional case. This allows you to cover the exposed parts.

In this way, the cover 5 is attached to the flange 3 of the holder body 1.
If you fit the lead wire on the bottom side of flange 3,
Also, the hole through which the lead wire is inserted can be hidden, and problems such as short circuit accidents and light leakage that have conventionally occurred can be prevented.

Further, according to the present invention, markings can be easily displayed using the bottom surface of the cover 5, and the display space is large, making marking easy and extremely convenient.
