Abstract

本实用新型涉及一种先合后断式继电器,包括底座、线圈、衔铁、支架、拉簧、上触点端子、下触点端子,其特征在于:上下触点端子间有滑杆,滑杆上有上下两片触桥,上下两片触桥由压簧连接,衔铁前有拨叉与上下两片触桥配合。本实用新型的优点是能使继电器在动作时,消除触头在切换过程中存在瞬间开路的过渡现象,不对电路或用电器造成损害。

Description

先合后断式继电器
技术领域
本实用新型涉及一种继电器,特别是一种先合后断式继电器。
背景技术
目前在日常使用的继电器在动作时,触头的切换过程中存在瞬间开路的过渡现象,对电路或用电器造成损害。
发明内容
本实用新型的目的是解决现有技术中继电器在动作时,触头的切换过程中存在瞬间开路的过渡现象,对电路或用电器造成损害的问题。本实用新型技术方案设计先合后断式继电器,包括底座、线圈、衔铁、支架、拉簧、上触点端子、下触点端子,其特征在于:上下触点端子间有滑杆,滑杆上有上下两片触桥,上下两片触桥由压簧连接,衔铁前有拨叉与上下两片触桥配合。本实用新型的优点是能使继电器在动作时,消除触头在切换过程中存在瞬间开路的过渡现象,不对电路或用电器造成损害。
附图说明
附图1为本实用新型的结构示意图,附图2为本实用新型的触桥示意图。
具体实施方式图中包括底座1、线圈2、衔铁3、支架4、拉簧5、上触点端子6、下触点端子7,其特征在于:上下触点端子6、7间有滑杆8,滑杆8上有上下两片触桥9、10,上下两片触桥9、10由压簧11连接,衔铁3前有拨叉12与上下两片触桥9、10配合。未加载时上下两片触桥9、10与上下触点端子6、7分别接触,当电磁线圈加载时,衔铁3被往下吸,衔铁3拨叉12拉动上下两片触桥9、10向下运动,上触桥9脱离上触点端子6,下触桥10始终接触下触点端子7,而当线圈2断电时,衔铁3拨叉12在拉簧5的作用下,反力将上下两片触桥9、10往上运动,上触桥9接触上触点端子6,压簧11随之将下触桥10拉离下触点端子7,保证触头在切换过程中不存在瞬间开路的过渡现象。
