[Means for solving the problem]
The waterproof socket according to claim 1 comprises a socket body having a threaded cylindrical portion on a front surface thereof and a lamp mounting portion for mounting a straight tube fluorescent lamp within the threaded cylindrical portion;
a waterproof ring having a substantially cylindrical shape and adapted to be threadedly engaged with the threaded cylindrical portion of the socket body, through which the straight tube fluorescent lamp is inserted;
a waterproof packing that is approximately cylindrical and is fitted into the waterproof ring, and through which the straight tube fluorescent lamp is inserted;
In this waterproof socket, the waterproof ring is screwed onto the threaded cylindrical portion of the socket body, and the waterproof ring presses the waterproof packing against the socket body, thereby tightly adhering the waterproof packing to the straight-tube fluorescent lamp and the socket body , thereby waterproofing the lamp mounting portion of the straight-tube fluorescent lamp,
the socket body is provided with a lamp pin insertion groove at least at one location of the threaded cylindrical portion, the lamp pin of the straight-tube fluorescent lamp being inserted through the groove so as to be penetrated from inside to outside, and the straight-tube fluorescent lamp is disposed in the lamp mounting portion; and a substantially annular waterproof packing abutment surface is provided on the same plane as a rear end surface of the lamp pin insertion groove or on an inner bottom surface of the threaded cylindrical portion located deeper than the rear end surface,
the waterproof ring has a waterproof ring abutment portion at a front end portion;
the waterproof packing has a lamp contact surface on its inner circumferential surface,
By screwing the waterproof ring into the threaded cylindrical portion, the lamp contact surface is brought into close contact with the straight-tube fluorescent lamp, and the waterproof ring contact portion presses the front end of the waterproof gasket in the axial direction, causing the rear end to contact the waterproof gasket contact surface.

請求項１記載の防水ソケットによれば、ソケット本体のランプピン挿通溝の後端面以上の奥のねじ筒部の内底面に、略環状の防水パッキン当接面を設け、防水パッキンの前端部を防水リングにより押圧して後端部をソケット本体内の防水パッキン当接面に当接させて防水構造としたため、従来例のＯリングを削減でき、Ｏリングの紛失の問題がなくなり、防水面も減らすことができる。その結果、防水リングの締付けによる防水パッキンへの摩擦力を低減し操作性を向上しながら、防水面への密着力を向上させることができ、従来より低コストかつ組立が容易で、さらに小さな締付け力の安定した防水性能が得られる。[0006]
According to the waterproof socket of claim 1, a generally annular waterproof gasket abutment surface is provided on the inner bottom surface of the threaded cylindrical portion deeper than the rear end surface of the lamp pin insertion groove of the socket body, and the waterproof structure is achieved by pressing the front end of the waterproof gasket with a waterproof ring so that the rear end abuts against the waterproof gasket abutment surface inside the socket body, thereby eliminating the need for an O-ring as in the conventional example, eliminating the problem of O-ring loss, and reducing the waterproof surface. As a result, the friction force on the waterproof gasket caused by tightening the waterproof ring is reduced, improving operability, while improving adhesion to the waterproof surface. This makes it cheaper and easier to assemble than conventional sockets, and provides stable waterproof performance with even smaller tightening forces.

請求項２記載の防水ソケットは、請求項1において、前記防水パッキンを前記防水リングに挿入し、前記防水リングを前記ねじ筒部に螺合して締付ける前の状態において、前記防水パッキンはその後端部を前記防水リングの外に突出する寸法をもつものである。
請求項２記載の防水ソケットによれば、請求項1と同様な効果のほか、防水リングに防水パッキンを挿入した状態で、ソケット本体のねじ部へ螺合しながら締めつける際、ランプピン挿通溝から防水パッキンの状態を確認できる。[0007]
The waterproof socket described in claim 2 is the same as claim 1, in that when the waterproof gasket is inserted into the waterproof ring and before the waterproof ring is screwed onto the threaded cylindrical portion and tightened, the waterproof gasket has a dimension such that its rear end protrudes outside the waterproof ring.
According to the waterproof socket described in claim 2, in addition to the same effect as claim 1, when the waterproof gasket is inserted into the waterproof ring and tightened while screwing it into the threaded portion of the socket body, the state of the waterproof gasket can be checked from the lamp pin insertion groove .

防水パッキン３はその前端部を防水リング当接部１６に当接するとともに後端部を防水パッキン当接面１ａに当接する。実施の形態では、ソケット本体１のランプピン挿通溝１２の後端面以上の奥のねじ筒部１１の内底面すなわち防水パッキン当接面１ａに先端が当接する円筒部４と、ランプＬと防水リング２の円筒内面との間に挾装される主筒部５から構成される。円筒部４の断面積は主筒部５より小さく形成される。防水パッキン３の円筒部４のソケット本体１の防水パッキン当接面１ａとの当接面には、円筒部４の断面積よりも小さくなった略環状の凸部９を設けてある。また主筒部５の防水リング２の内面の防水リング当接部１６の当接面にも同様の凸部７を設けている。これらの凸部７、９は防水パッキン当接面１ａおよび防水リング当接部１６の当接面に対して線接触に近い状態で接触するようになっており、防水リング２をソケット本体１のねじ筒部１１に螺合して、防水リング２を締めつけることにより防水パッキン３に作用する摩擦力を低減することができる。[0012]
The waterproof gasket 3 has its front end abutting against the waterproof ring abutment portion 16 and its rear end abutting against the waterproof gasket abutment surface 1a. In this embodiment, it is composed of a cylindrical portion 4 whose front end abuts against the inner bottom surface of the threaded cylindrical portion 11, i.e., the waterproof gasket abutment surface 1a, which is located deeper than the rear end surface of the lamp pin insertion groove 12 of the socket body 1, and a main cylindrical portion 5 which is sandwiched between the lamp L and the cylindrical inner surface of the waterproof ring 2. The cross-sectional area of the cylindrical portion 4 is smaller than that of the main cylindrical portion 5. A substantially annular protrusion 9, whose cross-sectional area is smaller than that of the cylindrical portion 4, is provided on the abutment surface of the cylindrical portion 4 of the waterproof gasket 3 with the waterproof gasket abutment surface 1a of the socket body 1. A similar protrusion 7 is also provided on the abutment surface of the main cylindrical portion 5 with the waterproof ring abutment portion 16 on the inner surface of the waterproof ring 2. These protrusions 7, 9 are designed to come into close to line contact with the waterproof packing abutment surface 1a and the abutment surface of the waterproof ring abutment portion 16, and by screwing the waterproof ring 2 onto the threaded cylindrical portion 11 of the socket body 1 and tightening the waterproof ring 2, the frictional force acting on the waterproof packing 3 can be reduced.
