るものである。[Detailed description of the invention] The present invention relates to a device for connecting a lead wire to a terminal of a lightning arrester, and its purpose is to connect the end of a lead wire drawn out from an overhead wire to a terminal on the side of the lightning arrester line. In this case, instead of tightening the lead wire by turning a set screw with a screwdriver, it can be easily and safely connected to and removed from the terminal of the surge arrester, and the lead wire connected to the surge arrester can be easily and safely disconnected at the connection point due to slight vibrations caused by wind pressure, etc. This is a terminal connection device for a lightning arrester that is free from the risk of connection failure due to loosening of the set screw, and is intended to be provided with a simplified structure and a reduced number of parts while being easy to attach and detach.

避雷器の端子接続装置として実公昭４６−７７２５号公
報に１電気機器の線路側端子接続装置ヨが提案されてい
る。As a terminal connection device for a lightning arrester, a line side terminal connection device for electrical equipment is proposed in Japanese Utility Model Publication No. 1987-7725.

これは、リード線を避雷器の端子に着脱を容易にしたも
のであるが、構造が複雑で部品数が多く組立てに時間を
要しコストダウンの支障となっていた。This makes it easy to attach and detach the lead wire to the terminal of the lightning arrester, but the structure is complex and the number of parts is large, requiring time to assemble, which is an obstacle to cost reduction.

また、リード線の避雷器への接続が押ネジで行なわれて
いるためリード線Ｃに疵がつき架空線及びリード線が風
圧等によって微振動を起し、接続部分に振動負荷が集中
して疲労断線するか、或いは該振動によって押ネジが緩
み電気的接続不良となる恐れがある。In addition, since the lead wire is connected to the lightning arrester with a set screw, the lead wire C may be damaged and the overhead wire and lead wire may vibrate slightly due to wind pressure, etc., and the vibration load concentrates on the connection part, resulting in fatigue. There is a risk that the wire may break or the set screw may become loose due to the vibration, resulting in poor electrical connection.

特に、避雷器のように保安機器が前記断線や接続不良と
なることは、肝心なときに保安機器としての用を威さず
、重大な問題である。In particular, when a safety device such as a lightning arrester becomes disconnected or has a poor connection, it impedes its use as a safety device at a critical time, and is a serious problem.

It has a vibration/bending protection tube 12 extending to the side, and this protection tube 1
2 supports the insulating cover 2, and the lightning arrester a is supported by the bottom plate 1 which is screwed into the insulating cover 2, and the slight vibration of the lead wire C caused by wind pressure etc. is caused by the vibration supporting the insulating cover 2.
Vibration is gradually absorbed by the bending protection tube 12, making it difficult for the vibration to be transmitted to the connection part of the lead wire C. Also, the lead wire C is compressed or soldered rather than screwed, so there is no loosening of the screw, and the vibration of the lead wire is It is possible to completely suppress the occurrence of wire breakage or poor connection at the connection part.
