本考案はいわゆるスワンベース型のランプソケ
ツトを主たる対象として、ランプの接点に接点圧

コイルバネのストロークをさらにとり、収縮長さ
をさらに小さくできるように構成することが可能
ならば、付勢力をさらに強力にできるのである。 Generally, so-called swan base type lamp sockets are configured to make contact with the lamp using the biasing force of a coil spring, and the biasing force exerted when the coil spring is contracted, so-called spring pressure, is increased to reduce the contact resistance with the lamp. Care is taken to reduce the However, most conventional coil springs are cylindrical or conical, and when they are contracted and the pitches of the coil springs become clogged, they overlap each other, so the length cannot be reduced below a certain level, so it is difficult to attach It had the drawback of not being able to make its forces powerful. That is,
If it is possible to make the stroke of the coil spring larger and the length of contraction smaller, the biasing force can be made even stronger.

のを防止している。 In the drawings, 1 is a cylindrical body made of synthetic resin that constitutes a lamp socket, 2 is a main body that also constitutes a lamp socket, and the two are combined to constitute the main body of the socket. The main body 2 includes a base member 3 made of synthetic resin and a cylindrical receiver 4 inserted into the base member. A terminal 5 is pulled out from the receiver 4 to the lower surface through the base 3, and the inner bottom surface of the receiver 4 is That is, the terminal 8 is inserted from the circular metal seat 7 installed in the recess 6 formed on the upper surface of the base member 3.
is also pulled out through the base member 3 to the lower surface. A coil spring 9 is placed on the metal seat 7 and applies an upward force to the movable contact 10, and the coil spring 9 contacts the lower surface of the contact 11 fixed to the center of the movable contact 10. The contactor 11-coil spring 9-metal seat 7-terminal 8 is electrically connected.
The coil spring 9 has a central portion having a smaller diameter than its adjacent portions, and an end portion that contacts the lower surface of the contactor 11 has a shape that gradually becomes smaller in diameter.
The movable contactor 10 is prevented from coming off by a locking piece 12 cut and formed on the receiver 4. Reference numeral 13 denotes a lamp, which is attached to the receiver 4 while maintaining conductivity by pushing a pin 15 protruding from the side of the base 14 into a J slot 16 formed at the end of the receiver 4 and giving it a slight rotation. Ru. The contact 17 on the end surface of the base 14 contacts the contact 11 of the movable contact 10, and the coil spring 9
The contact is stabilized by the biasing force. A chassis 18 fixes the body 1 by screwing screws 19 into insert screws 20 inserted into both sides of the base of the body 1. The upper peripheral edge of the base member 3 of the main body 2 rests on an annular protruding edge 21 formed on the inner peripheral surface of the body 1, and the lower peripheral edge of the base member 3 rests on a flexible material sandwiched between it and the chassis 18. The main body 2 is also fixed to the chassis 18 by being received by the annular waterproof ring 22 . A terminal lead-out portion 23 with a step in the center of the bottom surface of the base 3
is provided protrudingly and passes through the chassis 18. Terminals 5 and 8 also protrude in a stepped manner. A waterproof packing 24 made of a flexible material is fitted around the periphery of the opening 25 of the body 1, and has an insertion hole 26 for the lamp 13 facing the center of the opening 25. 13
This prevents rainwater from entering through the gap created between the body 1 and the body 1.
以上の構成においては可動接触子１０を介さず
に、直にコイルバネ９の端部をランプ１３の接点
１７に接触させてももちろんよい。 In the above configuration, the end of the coil spring 9 may of course be brought into direct contact with the contact 17 of the lamp 13 without using the movable contact 10.

に低減せしめることができる。 When the lamp 13 is installed as shown in Fig. 1 in the above configuration, the coil spring 9 will contract under the action of the drag force, and the small diameter part formed in the center will not overlap with the two adjacent parts, but will be The coil spring 9 can be contracted, and the length of contraction of the coil spring 9 can be made smaller than that of the conventional coil spring. Therefore, the urging force of the coil spring 9 in the contracted state is greatly improved, and the contact pressure of the lamp 13 against the contact point 17 can also be greatly increased, thereby making it possible to significantly reduce the contact resistance.

特徴を有するものである。 More specifically, the coil spring 9 is installed between the contact point 17 provided on the end surface of the base 14 of the lamp 13 and the base member 3 with or without the movable contact 10, from the base member 3 side. Toward the contact 17 side, there is a large diameter base, a central small diameter part, a large diameter part,
are formed in the order of small diameter end, and the small diameter end is contact point 1.
The central small diameter portion has an outer diameter that can be contracted without overlapping the large diameter base and the large diameter portion.

わりはない。 In this embodiment, conduction is achieved through the coil spring 9, but a lead wire may be fixed to the lower surface of the contact 11 of the movable contact 10 and drawn out through the base member 3 to the lower surface. In this case as well, the effect regarding the biasing force of the coil spring 9 remains the same.
