This lamp holder 1 has a light emitting diode (L
ED) 2 is held, and this light emitting diode 2 is provided in an emergency lighting device (not shown), a guide light, or the like, and functions as a pilot lamp (charging monitor) indicating the charging state of the built-in storage battery. The lamp holder 1 is composed of a substantially cylindrical holder body 3 made of a soft synthetic resin, an electric component unit 4 engaged with and held by the holder body 3, and the like. It is attached to the lower part of the emergency lighting fixture via the mounting bracket 5 formed as described above.

The electric component unit 4 has a rectangular plate-shaped mounting board 6, and the lead pins 2a of the light-emitting diode 2 are soldered and fixed to the lower surface of the mounting board 6, and the upper surface of the mounting board 6 is fixed. Is fixed by soldering while the base ends of the pair of lead wires 7 are electrically connected to the respective lead pins 2a of the light emitting diode 2, and the connector 8 is crimped to the end parts of these lead wires 7. Etc. are mechanically and electrically connected.

A substantially cylindrical outer cylinder portion 9 is formed on the upper side (back surface side) of the holder body 3 and has a substantially cylindrical fitting portion 10.
Is formed on the lower side (front side), and a mounting hole 11 having a circular cross section that vertically penetrates is formed in the central portion.

Further, on the outer cylinder portion 9 of the holder main body 3, engagement holding portions 14 having locking claws 12 are cut out so as to face each other, and the mounting substrate 6 is attached to the engagement holding portions 14. It is engaged and held from the upper side. In this state, the mounting board 6
The light emitting diode 2 attached to the lower surface of the holder is inserted from the upper side into the attachment hole 11 at the center of the holder body 3 and held therein.

Further, the outer cylinder portion 9 of the holder main body 3 is formed with a lead wire through hole 15 which is located in the middle of each engagement holding portion 14 and which communicates the inside and outside of the outer cylinder portion 9. The lead wire 7 connected to the mounting substrate 6 is drawn out through the lead wire through hole 15.

Further, since the lead wire 7 is inserted through the lead wire through hole 15, even if the lead wire 7 is pulled upward in a use state, an external force is not directly applied upward to the mounting substrate 6 on which the light emitting diode 2 is mounted. The mounting board 6 is designed so as not to fall off the holder body 3.

[0010]

SUMMARY OF THE INVENTION In the above conventional configuration,
Since both the mounting substrate 6 and the connector 8 connected to both ends of the lead wire 7 are large in size and cannot be inserted through the lead wire through holes 15 of the holder main body 3, the electric component unit 4 is installed in the assembly process of the lamp holder 1. The electric component unit 4 cannot be attached to the holder body 3 after completion.

Therefore, after inserting the base end portion of the lead wire 7 having the connector 8 connected to the tip end thereof into the lead wire passage hole 15,
After fixing the base end portion of the lead wire 7 to the mounting substrate 6 by soldering, or after inserting the lead wire 7 with the mounting substrate 6 connected to the base end portion into the lead wire through hole 15 over substantially the entire length. It is necessary to connect the connector 8 to the tip of the lead wire 7, and especially when the length of the lead wire 7 is large, the work of inserting the lead wire 7 into the lead wire through hole 15 is not required. It becomes complicated.

Further, since complicated work is required in the assembling process, there is a problem that workability is poor and manufacturing efficiency is poor.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an electric component holding device which can be easily assembled with good workability and has good manufacturing efficiency.
