Description

[Detailed description of the invention] This invention relates to a lighting device such as a street light, in which a lamp is attached to the tip of a pole, and prevents moisture from entering the device through the inside of the pole. The purpose is to prevent contact with the inner wall.

FIG. 1 shows a cross-sectional view of a conventional street light. At the tip of a hollow pipe-shaped pole 1 with an opening at its tip; A pole receiver 4 having a diameter is fitted onto the outside with a short cylindrical portion 20 provided at the lower center, and is secured by the locking portion 3.
A socket base 5, which has a socket 13 holding a lamp 14 on its center upper surface and a mounting bracket 10 with a terminal block 11 attached on its back surface, is placed on the crotch seat 2 of A substantially spherical glove 7 is placed on the top surface of the peripheral edge of the glove holder part 19 via a rubber cushion 6, and the stopper 8 fixed to the socket base 5 and the glove holder are attached to the part 19 in a detachable manner. The glove 7 is held and attached between them.

However, the power wire (not shown) inserted through the pole 1 is connected to the terminal block 11.
The terminal block 11 and the socket are connected by a lead wire 12.

In the above-mentioned conventional street light, moisture from the ground on which the pole is erected passes through the inside of the pole 1 and reaches the terminal block 11 and the socket 13.
The terminal block 11 may reach the socket base 5 due to uneven installation between the socket base 5 and the mounting bracket 10, resulting in poor insulation.
Pole 1 due to variations in installation to pole holder 4.
There was a risk that it would come into contact with the inner wall of the building and cause a short circuit.

The present invention has been made in view of the above points, and will be explained below based on the drawings.

2 and 3 show an embodiment of the present invention, which is a mounting bracket that replaces the mounting bracket 10 of the terminal block 11 in the conventional example shown in FIG. 1, and other configurations are the same as the conventional example. .

The mounting bracket 10 forms a substantially semicircular bent piece 15 at the lower end,
An electric wire holder 16 having a U-shaped cross section is attached with screws 21 below where the terminal block 11 is attached.

The lower piece 17 of the wire holder 16 has a substantially semicircular shape, and together with the bent piece 15 of the mounting bracket 10, forms a disc having a diameter slightly smaller than the inner diameter of the pole 1.

In addition, convex portions 18 are formed on both sides of the surface of the wire holder 16 facing the mounting bracket 10 to sandwich the power wire 22 in the gap formed between the mounting bracket 10 and the wire holder 16.
Even if a tensile force is applied to the power line 22 and the terminal block 11
This prevents the connection from becoming disconnected.

Then, the mounting bracket 10 with the power supply holder 16 attached while holding the power line 22 is inserted into the pole 1 as shown in FIG.
In this state, the bent piece 15 and the lower piece 17 substantially abut against the inner wall of the pole 1, positioning the mounting bracket 10 at substantially the center of the pole 1, and closing the inside of the pole 1.

In this way, the terminal block 11 attached to the mounting bracket 10 maintains a certain distance from the inner wall of the pole 1 so that there is no risk of short circuit, and also blocks moisture passing through the inside of the pole 1. socket 1
Prevents insulation defects such as 3.

The present invention is constructed as described above, and includes the bent piece 15 of the mounting bracket 10 to which the terminal block 11 is attached, and the lower piece 17 of the power presser 16 that holds the power line 22 connected to the terminal block 11.
By making the combined shape approximately equal to the inner shape of the hollow pole 1 and inserting it into the pole 1, the terminal block 11 attached to the mounting bracket 10 is positioned approximately at the center of the pole 1, and is connected to the inner wall of the pole 1. In addition, the inside of the pole 1 is substantially closed to block moisture from entering upward, thereby preventing poor insulation of the terminal block 11 and socket 13.
