話用保安装置に挿入できない等の欠点があつた。 Conventionally, carbon lightning arresters have been used in telephone security devices with emphasis on fail-safe properties for telephone subscribers. This carbon lightning arrester has carbon electrodes facing each other to form a discharge gap, and a long groove is formed on the top surface of the carbon electrode, and this long groove is used to attach it to a telephone security device. Because the discharge gap was made very narrow in order to obtain voltage, the application of lightning surges created discharge marks on the discharge surface, changing the discharge gap and making it easier to shoot.
Maintenance operations during periods of frequent thunderstorms were a problem.
For this purpose, a gas-filled lightning arrester element with a long life and good discharge characteristics is used, by sealing the openings at both ends of a cylindrical insulating tube with metal electrodes and sealing the discharge-inducing gas inside to widen the discharge gap. It has become like that. However, this gas-type lightning arrester has a different external shape from the above-mentioned carbon arrester, and does not have a long groove on its top surface like the carbon arrester, so it is easily
It had drawbacks such as not being able to be inserted into existing telephone security devices such as No.-31295 and No. 128230/1983.

When the upper electrode 10 is inserted into the long groove 2 from the insertion port 6a side of the guide groove 6, that is, from the direction of the arrow in FIG. The engagement step portions 13, 13 of the portions 11, 11 abut against the terminal end portion 7 of the guide groove 6, and the upper electrode 10 is positioned within the long groove 2 and fixed by the springiness of the sleeve portions 11, 11. The upper electrode 10 has both convex portions 2a,
It is supported on 2a, and a slight gap is formed between it and the bottom surface of the long groove.

Similarly, the other engaging claw 15, 15
is assembled by engaging the engagement protrusion 9 of the other engagement groove 8. With this assembly, the lightning arrester element 16 is pushed up by the lower electrode 14, so that the metal electrode 17 on the upper part of the lightning arrester element 16 is exposed between the protrusions 2a, 2a of the long groove 2 and comes into contact with the upper electrode 10.

However, since it has a plate-like insertion structure, it can be easily pulled out from the insertion port, making it easy to replace the lightning arrester element. In particular, since it has only a plug-in structure, there is no elasticity deterioration of the upper electrode due to repeated replacement, which is advantageous when the lightning arrester element is frequently replaced, such as in a lightning-prone area.

完全な接触を図ることができる。 In addition, when attached to the safety device, the contact piece of the safety device presses the upper electrode, so the lightning arrester electrode exposed from the bottom of the long groove can be reliably brought into contact with the upper electrode. The pressure using the spring force tightly presses the lower electrode and the upper electrode, and the convex portion and the lightning arrester electrode contact the upper electrode without loosening, thereby preventing contact failure. If a thin plate is used for the upper electrode,
Full contact can be achieved.

る。 Further, since the sleeve portion of the upper electrode is inserted into and guided by the long guide groove, insertion and removal can be performed freely and easily. Furthermore, by forming the starting end of the sleeve part into an engaging stepped part, it can be engaged with the terminal end of the guide groove for positioning, and the position can be fixed by the springiness provided by the use of the notch.
When the safety device is pulled out from the contact piece, the upper electrode can be prevented from coming off by the contact piece spring pressure.
