Description

换向开关 技术领域 本发明涉及电气系统开关技术领域， 特别地， 涉及一种换向开关。 背景技术 目前， 市场上的换向开关所采用的正、 反转机构， 基本分为两大类型： 第一类， 电子类正、 反转机构： 通过电子线路联接实现电机 （马达） 正、 反转功 能； 第二类， 机械类正、 反转： 通过机械结构联接实现电机 （马达） 正、 反转功能； 前者由于成本高昂， 应用极少； 后者因为成本较低、 易实现， 应用广泛。 其中， 机械类正、 反转的机构又包括侧面接触型： 相对于正、 反转联接部件的工 作部位， 输入端 1、输入端 2及输出端 1、输出端 2的对应工作部位都在其侧面。 这种 类型的正、 反转机构存在如下的问题： 每条回路 （例： 输入端 1 (2)， 正、 反转联接 部件， 输出端 1 (2)构成正、 反转一条回路）都通过单独一个正、 反转联接部件连通， 即每路回路的联接接触点都是单一的。 众所周知， 在每条回路的联接部位， 存在接触 电阻， 在材料相同、接触压力相等的情况下， 接触电阻的大小取决于接触面积的大小。 接触电阻越大， 回路的内阻 （回路内阻 =材料内阻 +接触电阻） 就越大， 通电情况下， 内阻越大， 发热量就越高。 另外， 在通电工作状态下， 开关不可避免需要承受一定的 冲击和振动， 单一的联接接触点容易使接触部位产生接触不良的现象， 从而发热严重， 影响开关工作性能。 发明内容 本发明目的在于提供一种换向开关， 以解决现有侧面接触型的换向开关的换向回 路内阻大、 容易发热， 而且抗冲击和抗振动性能差的技术问题。 为实现上述目的， 本发明提供了一种换向开关， 包括幵关本体及设置在幵关本体 上的成对设置并相互独立的输入端子和输出端子， 每对中包括一个输入端子和一个输 出端子， 一个输入端子通过多个相互独立的换向连接体与一个输出端子连通或断开， 多个相互独立的换向连接体同步运动地设置。 进一步地， 输入端子包括第一输入端子和第二输入端子； 输出端子包括第一输出 端子和第二输出端子， 第一输入端子、 第一输出端子、 第二输入端子以及第二输出端 子沿开关本体的周向顺次设置； 换向连接体包括第一组换向连接体和第二组换向连接 体， 第一输入端子可选择地通过第一组换向连接体与第一输出端子相连或通过第二组 换向连接体与第二输出端子相连， 第二输入端子可选择地通过第一组换向连接体与第 一输出端子相连或通过第二组换向连接体与第二输出端子相连。 进一步地， 第一组换向连接体包括沿开关本体的厚度方向平行设置的第一换向连 接体和第二换向连接体， 第二组换向连接体包括沿开关本体的厚度方向平行设置的第 三换向连接体和第四换向连接体。 进一步地， 开关本体内设置有转子安装槽， 转子安装槽内设置有换向转子， 换向 连接体设置在换向转子的侧壁上。 进一步地， 换向转子的侧壁上设置有与换向连接体的数量及位置相对应的相互独 立的连接体安装卡槽， 每个换向连接体相应地设置在一个连接体安装卡槽内。 进一步地， 换向转子的第一侧设置有沿轴向平行设置的相互独立的第一连接体安 装卡槽和第二连接体安装卡槽， 第一换向连接体和第二换向连接体分别设置在第一连 接体安装卡槽和第二连接体安装卡槽内； 换向转子的第二侧设置有沿轴向平行设置的 相互独立的第三连接体安装卡槽和第四连接体安装卡槽， 第三换向连接体和第四换向 连接体分别设置在第三连接体安装卡槽和第四连接体安装卡槽内。 进一步地， 输入端子和输出端子位于开关本体的外侧， 且输入端子和输出端子分 别通过位于开关本体内的输入端子连接体和输出端子连接体与换向连接体相连， 输入 端子连接体和输出端子连接体位于换向转子的外表面与转子安装槽的内侧壁之间。 进一步地， 换向连接体为 U形的换向连接体， 连接体安装卡槽为 U形槽， U形的 换向连接体的弧形底部与输入端子连接体和 /或输出端子连接体相连。 进一步地， 换向转子的顶端设置有用于控制换向转子转动的换向手柄。 本发明具有以下有益效果： 本发明提供的换向开关包括开关本体及设置在开关本体上的成对设置并相互独立 的输入端子和输出端子， 每对中包括一个输入端子和一个输出端子， 其中， 一个输入 端子通过多个相互独立的换向连接体与一个输出端子连通或断开， 多个相互独立的换 向连接体同步运动地设置。 本发明提供的换向开关在输入端子和输出端子之间采用多 个相互独立的换向连接体实现输入端子与输出端子之间的连通和断开， 增加了换向连 接体与输入端子或输出端子之间的接触面积， 降低了接触电阻， 提高了换向开关的承 载电流的能力； 同时， 由于触点增多， 在通电工作时， 能保证接触可靠性， 有效抗击 冲击和振动对开关性能的影响。 除了上面所描述的目的、特征和优点之外， 本发明还有其它的目的、特征和优点。 下面将参照图， 对本发明作进一步详细的说明。 附图说明 构成本申请的一部分的附图用来提供对本发明的进一步理解， 本发明的示意性实 施例及其说明用于解释本发明， 并不构成对本发明的不当限定。 在附图中： 图 1是本发明优选实施例的换向开关处于断开状态时内部结构示意图： 图 2是本发明优选实施例的换向开关处于第一方向连通时内部结构示意图； 图 3是本发明优选实施例的换向开关的整体结构示意图； 图 4是本发明优选实施例的换向转子与换向连接体的装配结构示意图； 以及 图 5是本发明优选实施例的两组换向连接体的结构示意图。 具体实施方式 以下结合附图对本发明的实施例进行详细说明， 但是本发明可以由权利要求限定 和覆盖的多种不同方式实施。 如图 1、 图 2和图 3所示， 本发明提供了一种换向开关， 包括开关本体 60及设置 在开关本体 60上的成对设置并相互独立的输入端子和输出端子，每对中包括一个输入 端子和一个输出端子， 一个输入端子通过多个相互独立的换向连接体与一个输出端子 连通或断开， 多个相互独立的换向连接体同步运动地设置。 本发明提供的换向开关在 输入端子和输出端子之间采用多个相互独立的换向连接体实现输入端子与输出端子之 间的连通和断开， 增加了换向连接体与输入端子或输出端子之间的接触面积， 降低了 接触电阻， 提高了换向开关的承载电流的能力： 同时， 由于触点增多， 在通电工作时， 能保证接触可靠性， 有效抗击冲击和振动对开关性能的影响。 输入端子包括第一输入端子 11和第二输入端子 31 ; 输出端子包括第一输出端子 21和第二输出端子 41， 第一输入端子 11、 第一输出端子 21、第二输入端子 31以及第 二输出端子 41沿开关本体 60的周向顺次设置； 换向连接体包括第一组换向连接体和 第二组换向连接体，第一输入端子 11可选择地通过第一组换向连接体与第一输出端子 21相连或通过第二组换向连接体与第二输出端子 41相连， 第二输入端子 31可选择地 通过第一组换向连接体与第一输出端子 21 相连或通过第二组换向连接体与第二输出 端子 41相连。 作为一种具体的实施方式，第一组换向连接体可以包括沿开关本体 60的厚度方向 平行设置的第一换向连接体 51和第二换向连接体 53， 第二组换向连接体可以包括沿 开关本体 60的厚度方向平行设置的第三换向连接体 52和第四换向连接体 54。每个换 向连接体之间都是互不连通的。 实际上， 每组换向连接体中的换向连接体的数量并不 限于两个， 也可以根据实际情况， 增加换向连接体的数量， 但是受到开关本体 60的体 积的限制， 随着每组中换向连接体的数量的增加， 每个换向连接体的沿开关本体 60 的厚度方向延伸的宽度就要相应地减小， 虽然单独的换向连接体的宽度变小了， 每组 换向连接体的两端与输入端子连接体或输出端子连接体之间的接触面积及接触触点还 是增加了， 还是能够从整体上提高换向开关的稳定性。 当然， 如果开关本体 60的体积 允许， 每个换向连接体的宽度也不一定要减小， 这还要取决于具体尺寸的限制。 具体地说，输入端子和输出端子位于开关本体 60的外侧， 且输入端子和输出端子 分别通过位于开关本体 60内的输入端子连接体和输出端子连接体与换向连接体相连。 如图 4和图 5所示， 为了实现换向的功能， 开关本体 60内设置有转子安装槽， 转 子安装槽内设置有换向转子 70， 换向连接体设置在换向转子 70的侧壁上， 输入端子 连接体和输出端子连接体位于换向转子 70的外表面与转子安装槽的内侧壁之间。换向 转子 70 的侧壁上设置有与换向连接体的数量及位置相对应的相互独立的连接体安装 卡槽， 每个换向连接体相应地设置在一个连接体安装卡槽内。 相应地，换向转子 70的第一侧设置有沿轴向平行设置的相互独立的第一连接体安 装卡槽和第二连接体安装卡槽， 第一换向连接体 51和第二换向连接体 53分别设置在 第一连接体安装卡槽和第二连接体安装卡槽内；换向转子 70的第二侧设置有沿轴向平 行设置的相互独立的第三连接体安装卡槽和第四连接体安装卡槽， 第三换向连接体 52 和第四换向连接体 54分别设置在第三连接体安装卡槽和第四连接体安装卡槽内。 换向连接体为 U形的换向连接体， 连接体安装卡槽为 U形槽， U形的换向连接体 的底部与输入端子连接体和 /或所述输出端子连接体相连。 换向转子 70的顶端设置有用于控制换向转子 70转动的换向手柄 71。 本发明提供的换向开关处于断开状态时， 每组换向连接体都不能同时连接一个输 入端子和输出端子， 即不能够形成一条连通回路。 例如， 如图 1所示， 第一组换向连 接体仅与第一输出端子连接体 20 相连， 第二组换向连接体仅与第二输出端子连接体 40相连。 当需要换向开关处于工作状态时， 如图 2所示， 可以通过旋转换向转子 70 使换向开关在第一个方向连通： 第一输入端子 11与第一输出端子 21之间通过第一换 向连接体 51和第二换向连接体 53连通； 第二输入端子 31与第二输出端子 41之间通 过第三换向连接体 52和第四换向连接体 54连通； 需要实现换向连接时， 可以再旋转 换向转子 70使换向开关在第二个方向连通：第一输入端子 11与第二输出端子 41之间 通过第三换向连接体 52和第四换向连接体 54连通，第二输入端子 31与第一输出端子 21之间通过第一换向连接体 51和第二换向连接体 53连通。 实际上， 本发明提供的换向开关能够解决换向连接体与输入端子或输出端子之间 接触面积小、 内阻大、 抗冲击和抗振动性能差的技术问题， 不仅可以适用于上述在将 换向连接体设置在开关本体 60的侧面的情况，也同样适用于将换向连接体设置在开关 本体 60的一端的情况。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的技 术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内， 所作的 任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
