Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative light used for decorating a Christmas tree or the like.

[0002]

2. Description of the Related Art Generally, in this type of decorative lamp, a terminal plate and lead wires are assembled to a socket body. That is, a through hole penetrating in the axial direction of the socket body is formed, and a terminal plate to which a lead wire having a relatively large-diameter coated outer cover is connected is inserted into the through hole from the bottom side of the socket body, The pair of terminal plates are fixed in the terminal plate mounting grooves on the inner wall of the socket body.

[0003]

However, the subsequent work, that is, the base end of the bulb support to which the bulb is assembled is inserted into the socket body from the top side of the socket body,
When attempting to bring the lead wire of the light bulb into contact with the pair of terminal plates fixed to the inner wall of the socket body, it is necessary to align and insert the light bulb support with respect to the socket body. There was a problem that they could not be fitted. On the other hand, when detaching the bulb support from the socket body, a part of the bulb support is grasped and pulled out.In this case, most of the bulb support is housed in the through hole of the socket body. Therefore, there is a problem that there is no place suitable for gripping and the detachment work cannot be performed smoothly.

The present invention has been made in view of the above circumstances, and it is easy to align the bulb support with respect to the socket body, the mounting operation is easy, and the bulb support is easily detached from the socket body. The purpose is to provide a decorative light.

[0005]

An ornamental electric lamp according to claim 1 comprises a light bulb, a light bulb support into which the light bulb is fitted, and a socket body having an opening portion for mounting the light bulb support at one axial end. In the decorative electric lamp, a pair of terminal plates that are electrically connected to the lead wires of the light bulb are assembled in the inner portion of the opening portion, wherein the opening portion is formed into a rectangular tube portion at the other end side in the axial direction of the socket body. The light bulb support has a prismatic portion that fits into the square tube portion, and the light bulb support comes into contact with the one end side of the release portion when mounted on the socket body. Is provided with the lid body portion, and the lid body portion is released at a position corresponding to a pair of parallel side surfaces of the prismatic portion when the light bulb support is mounted on the socket body. Notch that forms an opening between the end portion and the one end side It is characterized in that is provided.

[0006]

According to the ornamental electric lamp of the present invention, the lid portion of the light bulb support has a notch for forming an opening between the lid body and the one end of the opening when the light bulb support is mounted on the socket body. Since the portion is provided, it is easy to perform the attaching / detaching work of the socket body and the light bulb support by hooking the claw on the notch, and the notch is, of course, a pair of parallel to each other of the prismatic portion. Since it is provided at the position corresponding to the side surface,
It is easy to perform the alignment work when fitting the prismatic portion into the prismatic tubular portion of the socket body.
