Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packing that prevents tension and waterproofs electric wires passing through the main body of a lighting device, for example.

Conventional gaskets have a through hole in the center that penetrates in the axial direction, and two outer flanges that are parallel to the outer periphery.A wire is passed through the through holes, and one is inserted into the power supply hole of the device body. It was fitted around the power supply hole on the main body of the device.

However, in such conventional packings, when tension is applied to the wire, the wire may slip if the tension exceeds the frictional force at the through hole, and the wire is not effective in preventing the tension, and water may enter along with the slippage.

The present invention was developed in view of the above points and will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention, in which two outer flanges 2 are provided protruding from a substantially cylindrical base 1 at a distance approximately equal to the thickness of the instrument main body 6, and two outer flanges 2 are provided at the center of the base 1 is provided with a through hole 4 that penetrates in the axial direction, and a horizontal hole 41 that is approximately perpendicular to the through hole 4.
It is a packkin made up of.

However, this gasket is fitted into the power supply hole of the instrument main body 6 and is attached by fitting around the power supply hole of the instrument main body 6 between the two outer collars 2, and the power supply 3 is bent after passing through the through hole 4. Side hole 4
’ is inserted.

In this way, when tension is applied to the electric wire 3 to the left as shown in the opening in Figure 2, the electric wire 3 is inserted through the through hole 4 and the horizontal hole 4' in a curved manner, and due to the curvature, the electric wire 3 is inserted into the packing. It is firmly attached and the electric wire 3 is firmly tensioned without coming off, and the tension acts as a force of adhesion of the outer flange 2 to the instrument body 6, and the more the tension is applied, the more effectively the waterproofing effect works.

As described above, the present invention provides a packing having an outer flange 2 on the outer periphery that fits around the power supply hole of the main body of the device, and having an electric wire inserted through the central through hole penetrating in the axial direction. A horizontal hole 4' that intersects the through hole 4 is provided, and the electric wire 3 inserted through the through hole 4 is inserted into the horizontal hole 4'.
It is a packing that is characterized by being penetrated by the electric wire 3.
The tension is firmly fixed without being pulled out from the packing, and the more tension is applied to the electric wire, the closer the outer flange 2 is to the appliance body, increasing the waterproof effect.
