Abstract

一种压力开关簧片接触结构，它主要由簧片及压片机构组成，所述的簧片为W形状，形成三个端臂和一个端部，其中二侧端臂的端点固定，中间端臂的端点和端部上各设置有方向相反的电触点，它们分别与上部固定触点常接触，与下部固定的触点常断开，在簧片中间位置上方设置有由传动环和传动杆构成的压片机构，从而使其具有结构简单、紧凑，使用方便、可靠，装配精度高，产品加工简单，制造成本低等特点。

Description

压力开关簧片接触结构
技术领域
本实用新型涉及的是一种压力开关或类似产品上的簧片接触开关装置，属于机械式接触式开关装置。
背景技术
在现有技术中，压力开关的簧片接触开关结构如附图1所示，它由上下簧片11、12及上部的压片机构组成，簧片上相应设置有电触点13。所述的压片机构由传动环14和中间传动杆15构成。传动环14与上簧片11接触，低压动作时，传动环14向下推动上簧片11使上下电触点接触，电路导通；传动杆15与下簧片12接触，高压动作时，传动杆向下推动下簧片12使已接触的两个触点分开，电路断开。另外，三态开关的中压动作采用独立的动作机构。上述结构的簧片接触开关基本上采用了至少二个动簧片并分别由压片机构带动工作，因而结构较为复杂，执行动作不够灵活，可靠性差，制造成本也高。
发明内容
本实用新型的目的在于提供一种结构简单，制造成本低，装配安装精度高的压力开关簧片接触结构。它主要由簧片及压片机构组成，簧片上设置有电触点，所述的簧片为W形状，形成三个端臂和一个端部，其中二侧端臂的端点固定，中间端臂的端点和端部上各设置有方向相反的电触点。
所述的中间端臂端点的上面设置有电触点，它与上部固定触点常接触，簧片的端部下面设置有电触点，它与下部固定的触点常断开。
所述的簧片中间位置上方设置有由传动环和传动杆构成的压片机构。本实用新型与现有技术相比，具有结构简单、紧凑，使用方便、可靠，装配精度高，产品加工简单，制造成本低等特点。
附图说明
图1是现有技术的结构示意图。
图2是本实用新型的簧片结构示意图。
图3是本实用新型的结构示意图。
具体实施方式
下面将结合附图对本实用新型作详细的介绍：图2、图3所示，本实用新型主要由簧片21和压片机构组成。簧片21为W形状，形成有三个端臂22、23、24和一个端部25，其中二侧端臂A臂22和C臂23的端部固定，而中间端臂B臂24和簧片21的端部25上分别设置有方向相反的电触点26、27，其中B臂24上面设置有电触点26并与上部的触点28常接触；簧片的端部25下面设置有电触点27并与下部的触点29常断开。在簧片21的中间上部设置有由传动环30和传动杆20构成的压片机构。低压时，传动环30向下压A臂22和C臂23，簧片21下移，簧片21的端部25上的电触点与下部的触点29接触，电路接通；高压时，中间传动杆20向下压B臂24，B臂24上的电触点26与其上部的触点28断开，电路断开。
