この発明は防爆型照明器具に関するものであ

従来の防爆型照明器具を第１図に示している。

続するリード線である。 A conventional explosion-proof lighting fixture is shown in FIG.
That is, in this explosion-proof lighting fixture, a socket adapter 1 is fitted to both ends of a cylinder 2, a socket 3 is inserted into this adapter 1, and a fluorescent lamp L placed inside the cylinder 2 is connected. It is used for. Therefore, adapter 1 is connected to cylinder 2.
It is cylindrical and has a collar 4 projecting from its end. Furthermore, a lead wire terminal insertion hole 6 is formed for installing the relay lead wire 5 inside the cylinder 2.
In addition, 7 is a plunger that receives the lamp pin, 8 is a pressing spring, 9 is a lamp pin holder, 10 is a pin provided in the socket 3 and connected to the lead wire terminal 11, and 12 is a lead that connects the pin 10 and the lamp pin holder 9. It is a line.

た。 However, since the adapter 1 and the relay lead wire 5 cannot be connected within the cylinder 2, the connection work is as shown in FIG. 2. That is, Figure a shows a state in which one end of the relay lead wire 5 is connected to one adapter 1 and inserted into the cylinder 2, and Figure b shows a state in which the other adapter 1' is connected to the other end of the relay lead wire 5. Figure c shows the state in which the adapter 1' has been fitted into the cylinder 2 and the installation has been completed. As a result, the relay lead wire 5 needs to be longer than the length of the cylinder 2 for connection, and in the completed state, the relay lead wire 5 becomes slack as shown in Figure c, and the shadow of the lead wire is cast when the light is turned on. A problem arose that I didn't like.
そこでこのリード線をカールコードにしたり、
たれないように仕切り板を入れてることや、あら
かじめランプ、ソケツト、中継リード線を組立て

た。 So I made this lead wire into a curl cord,
It could be considered to insert a partition plate to prevent the lamp from dripping, or to assemble the lamp, socket, and relay lead wire in advance and insert them into the cylinder as one, but this is not suitable in terms of ease of assembly and lamp replacement.
したがつて、この発明の目的は、組立性および
ランプ交換性を抵下させることなく、中継リード
線のたるみを防止できる防爆型照明器具を提供す
ることである。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an explosion-proof lighting fixture that can prevent the relay lead wire from sagging without compromising ease of assembly and lamp replacement.
この発明の一実施例を第２図に示す。すなわ

第１図と同様である。 An embodiment of this invention is shown in FIG. That is, this explosion-proof lighting fixture is compatible with the above-mentioned adapter 1.
In this embodiment, grooves 14 are formed on both sides of the collar 13, which is formed intermittently in the circumferential direction, so that the collar 13 can be bent in the radial direction. Other details are the same as in FIG.
第４図はその接続順序を示している。同図ａは

状態である。 FIG. 4 shows the connection order. Figure a shows a state in which one end terminal of the relay lead wire 5 is inserted into one adapter 15 and connected to the end of the cylinder 2, and Figure b shows a state in which the collar 13 is recessed inward using the split groove 14. Figure c shows the state in which the adapter 15 is inserted into the cylinder 2 and the other end terminal of the joint lead wire 5 is connected to the other adapter 15'.
At the same time, the adapter 15' is pulled out to the end of the cylinder 2 and hung on the collar, and at the same time, the adapter 15' is hung on the other end of the cylinder 2.
その結果、中継リード線５の長さをシリンダ２

果を達成できる。 As a result, the length of the relay lead wire 5 was changed to the length of the cylinder 2.
By making the length approximately the same as that of , it is possible to prevent slack from occurring within the cylinder 2 . Moreover, adapter 15,
The operation of 15' is extremely simple. Next, attach the lamp to cylinder 2 from one of adapters 15 and 15'.
When the socket is inserted into the adapter 15, 15', the socket and lamp pin are connected. To replace the lamp, remove only the socket. In addition to the above-mentioned means, the same effect can be achieved by means of engagement such as a concave-convex engagement or a pawl engagement between the cylinder and the adapter.

線のたるみを防止できるという効果がある。 As described above, the explosion-proof lighting equipment of this invention is
Prepare an adapter that allows you to attach a lamp socket.
One adapter is attached to both ends of the cylinder so that it can slide a certain distance into the cylinder, and a lead wire is stretched between the adapters and the lamp is inserted into and removed from the cylinder through the adapter, improving ease of assembly and lamp replacement. This has the advantage that it is possible to use a lead wire length that matches the cylinder length, and to prevent the lead wire from sagging.
