一种用于电子式电度表的磁保持继电器
摘要：
本实用新型公开了一种用于电子式电度表的磁保持继电器，包括箱体和箱门，所述箱体一侧通过铰链连接有箱门，所述箱体内壁活动连接有滑块，所述滑块下方通过螺钉连接有散热片，所述散热片一侧转动连接有风扇，所述滑块上表面通过螺钉连接有一号弹簧，所述一号弹簧一端通过卡扣连接有陶瓷纤维垫片，所述箱体内壁开设有滑槽，所述滑槽一侧固定连接有二号弹簧，所述二号弹簧一侧通过螺钉连接有金属网罩，所述接线孔表面粘连有遇水膨胀止水条。本实用新型通过二号弹簧可有效的缓冲带给滑块的应力作用，从而使陶瓷纤维垫片收到一个缓冲力，并通过蓄电池驱动风扇运转，可加快散热片周围空气的流动，提高散热效率。
摘要（英）：

The utility model discloses a magnetic latching relay for electronic type electric meter, which comprises a box body and a box door, there is the chamber door box one side through hinged joint, box inner wall movably connected has the slider, there is the fin slider below through the screw connection, fin one side is rotated and is connected with the fan, the slider upper surface has the spring no. One through the screw connection, no. One spring one end is connected with the ceramic fibre gasket through the buckle, the spout has been seted up to the box inner wall, no. Two springs of spout one side fixedly connected with, no. Two there is the metal screen panel spring one side through the screw connection, the surface adhesion of wiring hole has the water of chance inflation sealing rod.The utility model discloses a no. Two springs can effectual buffering bring the stress action of slider to make the ceramic fibre gasket receive a cushion effect, and through battery drive fan operation, can accelerate fin surrounding air's flow, carry high heat dissipation efficiency.
