There is a drawback that this is easily lost and that the waterproof ring has poor tightening operability due to the large contact surface and high frictional resistance. Therefore, an object of the present invention is to reduce the number of waterproof parts, reduce the frictional resistance of a waterproof portion caused by tightening of a waterproof ring, and provide a large force for compressively deforming a conventional O-ring in a lamp having a lamp pin insertion groove. It is an object of the present invention to provide a waterproof socket which can improve the tightening operability of a waterproof ring without requiring a waterproof ring.

Is formed smaller than the main cylindrical portion 5. On the contact surface of the cylindrical portion 4 of the waterproof packing 3 with the waterproof packing contact surface 1a of the socket body 1, a substantially annular convex portion 9 smaller than the cross-sectional area of the cylindrical portion 4 is provided. Further, a similar convex portion 7 is provided on the contact surface of the inner surface of the waterproof ring 2 of the main cylindrical portion 5 with the waterproof ring contact surface 1a. The projections 7 and 9 come into contact with the waterproof packing contact surface 1a and the contact surface of the waterproof packing contact portion 16 in a state close to linear contact. The frictional force acting on the waterproof packing 3 can be reduced by screwing the waterproof ring 2 by screwing into the screw cylinder 11.

る。A thin portion 8 is provided near the front end of the main cylindrical portion 5 and a lamp contact surface 8a is provided on the inner peripheral surface of the thin portion 8. A waterproof ring contact portion 16 is formed by tightening the waterproof ring 2.
Then, the compressive force acting on the waterproof packing 3 in the axial direction is released while being deformed in the lamp direction by the thin portion 8, and the lamp contact surface 8a of the inner peripheral surface of the thin portion 8 is brought into close contact with the lamp tube wall. Acts to compress the waterproof packing 3 in the axial direction. At this time, since the cross-sectional area of the cylindrical portion 4 is smaller than that of the main cylindrical portion 5, the compressive force in the lamp axis direction is reduced by the convex portion at the tip of the cylindrical portion 4. 9 and the waterproof packing 3
Can reliably add adhesion to the two waterproof surfaces,
Stable waterproofing performance can be obtained with a smaller tightening force than before.

The rear end of the waterproof packing 3 is projected outside the waterproof ring 2 by a dimension b in a state of contact with the front end of the waterproof ring 2. Further, an outer flange portion 6 is provided at an intermediate portion of the cylindrical portion 4 of the waterproof packing 3 so as to be in contact with the inner surface of the waterproof ring 2 and engage with the waterproof ring. In the embodiment, the outer flange portion 6 is locked to a locking concave portion, for example, a screw portion 10. Further, the outer flange portion 6 is formed so as to be continuous with the step portion 24 due to a difference in wall thickness at the boundary between the cylindrical portion 4 and the main cylindrical portion 5. The length from the outer flange 6 to the rear end of the waterproof packing 3, that is, the projection 9 is substantially equal to the length of the lamp pin of the lamp L.

Waterproof. According to this embodiment, the socket body 1
Screw cylinder portion 1 deeper than the rear end face of the lamp pin insertion groove 12
A waterproof packing contact surface 1a having a substantially annular shape is provided on the inner bottom surface of the socket 1. The waterproof packing 3 has a front end portion in contact with the waterproof ring contact portion 16 and a rear end portion with the waterproof packing contact surface in the socket body 1. Since the waterproof structure is provided by contacting the O-ring 1a, the number of O-rings in the conventional example can be reduced, the problem of loss of the O-ring can be eliminated, and the waterproof surface can be reduced. As a result, the frictional force on the waterproof packing 3 due to the tightening of the waterproof ring 2 can be reduced, and the operability can be improved, and the adhesion to the waterproof surface can be improved.
Further, stable waterproof performance with a small tightening force can be obtained.

Since it is thinner than the main cylinder part 5, the compression force in the lamp axis direction per unit area of the cylinder part 4 is larger than that of the main cylinder part 5, and the cylindrical part 4 is further contacted with the socket body 1. Is formed, the contact force can be improved while reducing the frictional force generated at the waterproof packing contact surface 1a, and is stable with a smaller tightening force than before. Waterproof performance is obtained.

ば防水性が保てるのか分かりにくかった。When the waterproof packing 3 is inserted into the waterproof ring 2 and the front end of the waterproof packing 3 is in contact with the front end of the waterproof ring 2, the rear end of the waterproof packing 3 is projected out of the waterproof ring 2. Therefore, when the waterproof ring 2 is screwed into the socket body 1, the waterproof packing 3 first comes into contact with the waterproof packing contact surface 1a, so that a waterproof effect can be obtained immediately, and a tightening of the waterproof ring 2 provides a locking effect. Can be Alternatively, in the case of a pinched socket, the socket body 1 has a lamp pin insertion groove 12 and the waterproof ring 2 with the waterproof packing 3 inserted therein.
When tightening while screwing in, the tight contact state of the contact portion of the waterproof packing 3 can be confirmed from the lamp pin insertion groove 12.
In the past, since the waterproof packing was attached inside the end face of the waterproof ring, it was difficult to understand to which position the waterproof ring could be secured to maintain waterproofness.

きる。Further, since the waterproof packing 3 is provided with an outer flange 6 which is in contact with the inner surface of the waterproof ring 2 and is engaged with the waterproof ring 2 at a middle portion of the outer surface thereof, the outer flange 6 of the waterproof packing 3 is provided.
Is locked to the waterproof ring 2, the waterproof packing 2 is hard to come off and hard to come off. That is, even when the waterproof ring 2 is removed from the use state of the appliance, the waterproof packing 3 does not fall off the waterproof ring 2, and acts by tightening the waterproof ring 2 on the main cylindrical portion 5 and the cylindrical portion 4 of the waterproof packing 3. The step 24 is adjusted by adjusting the position of the step 24 or the outer flange 6 continuous with the step 24 so that the step 24 is connected to the socket body 1.
Of the waterproof packing 3
Can be set in the main cylinder 4 and the cylindrical section 5,

The waterproof ring 2 is provided with an inclined step 23 in the middle to reduce the diameter at the front end side. The inclined surface of the waterproof ring contact portion 16 at the front end is enlarged. The waterproof packing 3 reduces the diameter of the main cylindrical portion 5 in accordance with the waterproof ring 2, inclines the front end portion toward the center side, forms a convex portion 9 that abuts against the waterproof ring contact portion 16, and forms an inner peripheral edge of the front end. It is a lamp contact portion 8a. When the waterproof ring 2 is tightened, the convex portion 9 becomes the waterproof ring contact portion 1
While being pushed toward the center in the radial direction along the slope of 6, it adheres closely,

A substantially annular waterproof gasket contact surface is provided on the inner bottom surface of the screw cylinder part deeper than the rear end surface of the lamp pin insertion groove of the socket body. Since the waterproof structure is formed by contacting the portion with the waterproof packing contact surface in the socket body, the O-ring of the conventional example can be reduced, the problem of loss of the O-ring can be eliminated, and the waterproof surface can also be reduced. As a result, it is possible to improve the adhesion to the waterproof surface while reducing the frictional force on the waterproof packing by tightening the waterproof ring and improving operability,
Low cost, easy to assemble, and stable waterproof performance with small tightening force are obtained.
