本发明涉及继电器技术领域。
继电器是一种电子控制器件,它具有控制***(又称输入回路)和被控制***(又称输出回路),通常应用于自动控制电路中,它实际上是用较小的电流去控制较大电流的一种“自动开关”。故在电路中起着自动调节、安全保护、转换电路等作用。
继电器通常包括线圈组件,线圈组件包括线圈架、漆包线和线圈引脚,线圈架具有绕线窗口,漆包线是缠绕在线圈架的绕线窗口处,线圈引脚则是装在线圈架上,线圈引脚结构中的一部分是伸到线圈架的绕线窗口内用来与漆包线相连接,线圈引脚的结构中的另一部分是伸到线圈架外,用来与驱动信号(即控制信号)相连接,以在驱动信号驱动下使漆包线工作。
现有技术的继电器线圈组件的线圈引脚中,用来与驱动信号相连接的方式主要有两种,一种是将线圈引脚中用来与驱动信号相连接的结构设计成插接脚,驱动信号的引入则为插槽结构,通过线圈组件的线圈引脚的插接脚与插槽结构相配合,实现将驱动信号接至漆包线;另一种是将线圈引脚中用来与驱动信号相连接的结构设计成焊接脚,驱动信号的引入则为信号线,通过将信号线搭在线圈组件的线圈引脚的焊接脚上直接焊接连接,实现将驱动信号接至漆包线。对于以信号线引入驱动信号的结构,由于将信号线搭在焊接脚上直接焊接,容易产生虚焊而造成继电器不工作。
另一继电器包括磁路部分和底座,现有技术中,在将磁路部分装入底座固定时,通常是采用劈铆或热铆的方式来实现磁路部分装入底座后的防退出。采用劈铆时,是利用与线圈装在一起的轭铁***底座的通孔中,然后对金属零件(即轭铁)的端部进行劈开,从而防止装入磁路部分从底座上退出,但是,采用金属劈铆后,劈开位置易生锈氧化,会影响继电器的正常使用;采用热铆时,是利用线圈架来装入底座,在压入部件(即线圈架)的正面或反面对压入部件的塑料部分进行热熔,使其塑料变形后扩大,从而保证线圈架装入底座后不会退回,但是,采用热铆工艺无法实现在自动化装配过程中超行程的调整,也就无法实现自动化装配过程中的免校正问题。
另外,为了在自动化装配过程中实现免校正,需要进行超行程调整,对于小型、ISO、PCB常规继电器,由于其零件较小,在产品免校正的提升方面通常采用直接法,即通过对铁芯极靴与轭铁刀口的落差大小进行微调整,来满足继电器的参数方面的要求。而对于大电流继电器,由于继电器本身体积和零件较大,同时,材料硬度较高,用现有技术的调整方法不能满足和达到调整的目的。
另一种继电器包括外壳、底座、线圈组件、铁芯、轭铁、衔铁、动簧片和静簧等部件,线圈组件呈卧式安装在底座上,即相当于线圈组件的线圈架的铁芯安装孔的轴线是呈水平设置,铁芯装在线圈组件的线圈架的铁芯安装孔中,铁芯的第一端部(即头部)的端面设为极面,轭铁为L型,轭铁的一边与铁芯的第二端部(即尾部)相固定,轭铁的另一边适配在线圈组件的线圈架的上侧的绕线窗口边,动簧片也为L型,动簧片的一边在轭铁的另一边的上面与轭铁相固定,动簧片的另一边与衔铁相固定,衔铁的上部适配在轭铁的另一边的端部的刀口处,且衔铁或动簧片的上端高出所述轭铁的另一边的上面,外壳装在底座上并将线圈组件、铁芯、轭铁、衔铁和动簧片等部件容纳在外壳内。这种结构的继电器,当外壳受到来自上面方向的冲击或挤压时,外壳的顶面内壁将向下变形,变形到一定程度时就会压到衔铁或动簧片的上端,致使衔铁或动簧片被卡死而无法动作,从而导致继电器失效。
另一种继电器是一种电子控制器件,是当输入量(激励量)的变化达到规定要求时,在电气输出电路中使被控量发生预定的阶跃变化的一种电器。继电器借助设置于内部的电磁装置,通过对线圈通入较小的电流,使得线圈产生磁场,利用磁场的产生或消失而吸合或松开衔铁,进而驱使动触桥上的动触点与静簧端子上的静触点闭合或断开,实现控制大电流运作。在现有继电器中,继电器的触点吸合后,没有相应的检测组件来检测触点是否导通,一旦触点不导通或触点粘接,在继电器使用时很难快速地检测并反馈出问题;另一方面,继电器的触点开闭次数也有一定的寿命要求,而现有的继电器没有对继电器的触点开闭次数进行统计,当达到失效次数时将会影响继电器的准确应用。
另一种电磁继电器在底座上装有两个静簧(作为负载端子),每个静簧上设有一个静触点,磁路部分中的线圈呈卧式安装在底座上,铁芯的一端设为极面,铁芯的另一端与轭铁相固定,轭铁为L型,除了轭铁的L型的第一部分与铁芯的另一端相固定外,轭铁的L型的第二部分则配置在线圈的旁边(即线圈架的绕线窗口外),轭铁的L型的第二部分的端头作为轭铁的刀口用来配合衔铁,柔性的动簧片也弯成大致L型,动簧片的L型的第一部分与轭铁的L型的第二部分相固定,动簧片的L型的第二部分则与衔铁相固定,使得衔铁能够以轭铁的刀口为转轴吸向铁芯的极面,动簧片的L型的第二部分设有桥接片,桥接片的两端各设有一个动触点,用来桥接两个静簧上的静触点。这种结构的电磁继电器,当应用于大电流环境时,触点分断时燃弧比较大,产品容易失效。

与现有技术相比较,本发明的有益效果是:
1、本发明由于在线圈架的一端的凸缘向下设有第一挂钩部件,底座的对应位置设有第一卡孔,线圈架的第一挂钩部件配合在底座的第一卡孔中,使包含有线圈架和动簧衔铁部件的整体部件在对应于第一卡孔的位置处沿着竖向和垂直于铁芯安装孔的轴线的水平方向被限位,而沿着铁芯安装孔的轴线方向存在可移动的第一间隙;在线圈架的另一端的凸缘向下延伸设有第二挂钩部件,底座的对应位置设有第二卡孔,所述线圈架的第二挂钩部件配合在底座的第二卡孔中,使所述整体部件在对应于第二卡孔的位置处沿着竖向和垂直于铁芯安装孔的轴线的水平方向被限位,而沿着铁芯安 装孔的轴线方向存在可移动的第二间隙;从而利用所述第一间隙和第二间隙实现触点超行程的调节。本发明的这种结构,既实现了线圈架与底座之间的钩挂固定,避免了现有技术采用劈铆固定所带来的弊端,而且还能够实现大电流继电器的超行程调整。

3、本发明由于采用了在金属铆钉的顶部设有台阶,将金属导电片的第一通孔配合在所述金属铆钉的台阶处。本发明的这种结构,可以利用金属铆钉的台阶来增加金属导电片与静簧的导电面积,提高导电可靠性。
4、本发明由于采用了在塑料体中,在对应于所述两个静簧的凸部的周边还分别设有让位区,在两个静簧的凸部分别套接有弹簧,弹簧在对应的让位区中被压缩在所述金属导电片与所述静簧的主体部之间。本发明的这种结构,利用弹簧的可变形性,在弹簧变形后始终与金属导电片、静簧的主体部相接触,从而可以保证信号诊断端子(即金属导电片)与负载端子(即静簧的主体部)之间的可靠连接,进一步保证了诊断信号的传递,从而可以保证***对监测信号的有效读取。
5、本发明由于采用了信号线为软导线,且信号线的一端连接金属导电片,信号线的另一端与一个连接器相连接,本发明是利用软导线来消除硬连接(金属片与金属片直接连接,容易脱落)之间所产生的应力,从而提高了连接的可靠性。
以下结合附图及实施例对本发明作进一步详细说明;但本发明的一种负载端子带信号监控的大电流继电器不局限于实施例。
本发明还提供一种桥式大电流电磁继电器,通过结构改进,在应用于大电流环境时,可提升载流能力,降低触点处的发热,减小触点分断时的燃弧,从而提升产品的性能。
本发明的桥式大电流电磁继电器,包括底座、安装在底座上的两个具有刚性特征的静簧、呈卧式安装在底座上的线圈以及连接于匹配在线圈的附近的衔铁和轭铁之间的具有柔性特征的动簧片;在动簧片的连接有所述衔铁的一端还固接具有刚性特征 的桥接片,并使桥接片的两端分别与两个静簧相对应;所述每个静簧上分别设有两个静触点,所述桥接片的两端分别设有两个动触点,且四个动触点呈一字型排列,当所述线圈工作而使所述桥接片的两端与两个静簧相接触时,所述桥接片的两端的两个动触点分别与两个静簧上的两个静触点对应相接触。
所述桥接片的两端的两个动触点和两个静簧上的两个静触点分别设为方形结构。
所述桥接片的两端的两个动触点和两个静簧上的两个静触点的触点表面分别设为向外凸出的弧面。
所述轭铁为L型,轭铁的L型的一边为第一部分,该第一部分与铁芯相固定,轭铁的L型的另一边为第二部分,所述第二部分配置在线圈的上面。
所述的两个静簧分别设在所述桥接片与所述线圈之间。
所述的两个静簧分别对称装在底座的两侧。
所述底座中,在对应于桥接片的背向动触点的一面还装有止挡块。
所述止挡块中,还装有缓冲垫。
与现有技术相比较,本发明的有益效果是:
1、本发明在每个静簧上分别设有两个静触点,在所述桥接片的两端分别设有两个动触点,且四个动触点呈一字型排列,当所述线圈工作而使所述桥接片的两端与两个静簧相接触时,所述桥接片的两端的两个动触点分别与两个静簧上的两个静触点对应相接触。本发明的这种结构,是在每个负载端子(即静簧)上同时设有并列的两个触点,这两个触点实现并连,而在动簧片的桥接片上对应设有的四个触点,并让桥接片上的四个触点分别于负载端子上的两个触点两两对应,两个负载端子(即静簧)则通过桥接片实现串联,双触点在负载端子端接通时,双触点并联使得等效的电阻减半(也相当于电流分流,可提升载流能力),因此在同等电流条件下,功耗量降低至原来的1/2,因此大大降低触点的功耗量,即降低触点处的发热,从而提升产品性能——负载能力更高;两个负载端子借助桥接片串联,实现电流回路的同步双断开也使得出现的电弧能量减半,达到减小触点分断时的燃弧的目的。
2、本发明将桥接片的两端的两个动触点和两个静簧上的两个静触点分别设为方形结构,以及将桥接片的两端的两个动触点和两个静簧上的两个静触点的触点表面分别设为向外凸出的弧面。本发明的这种结构,可以利用方形结构和弧形表面的配合使动静触点间的接触为线接触,从而提高动静触点间接触的可靠性。
3、本发明在动簧片的连接有所述衔铁的一端还固接具有刚性特征的桥接片,并使桥接片的两端分别与两个静簧相对应。本发明的这种结构,使得动簧片只需承担动簧部件的来回运动的机械疲劳强度而不承担载流能力,而桥接片只承担载流能力而不承担载抗机械疲劳能力,在具有相同灭弧能力的情况,能随机选择动簧材料而不需要选择特殊的动簧材料,同时负载回路路程更短(电流只流经桥接片而不经过动簧片), 即更短的路程则有更小的线路电阻,因此,在相同负载(电流)的条件下,发热量会更小。

与现有技术相比较,本发明的有益效果是:
本发明的一种继电器线圈组件,在线圈引脚3的第一卡槽331的两侧槽壁中的其中一侧槽壁的靠近开口边沿设有倒钩332,所述第一卡槽331的两侧槽壁中的其中一侧槽壁的对应于信号线的配合位置处还设为由内向外使开口呈逐渐增大的斜面段333,以在对设有倒钩的所述的其中一侧槽壁的外部施力时利用所述斜面段333将所述信号线挤压在所述第一卡槽331内,并利用所述倒钩332防止所述信号线400脱出。本发明的这种结构,通过在第一卡槽331内设置斜面,相当于形成一个三角区,柔性信号线从第一卡槽的开口处沿着倒钩332边缘位置处压入第一卡槽331内后,通过对第一卡槽331的具有倒钩的一侧槽壁的外部进行挤压,使该侧槽壁的倒钩332向另一侧槽壁方向发生变形,使槽内空间变小,信号线400与第一卡槽331呈过盈配合,从而实现将信号线400卡住, 使之不容易脱落。

本实施例中,所述第二挂钩部件6与所述第二卡孔320的沿着垂直于铁芯安装孔的轴线的水平方向的两个相对的孔壁之间呈过渡配合,使所述整体部件在对应于第二卡孔320的位置处沿着垂直于铁芯安装孔的轴线的水平方向被限位;所述第二卡孔的沿着垂直于铁芯安装孔的轴线的水平方向的两个相对的孔壁中的其中一个还设为波浪形壁面322,以在利用所述第一间隙和第二间隙实现触点超行程的调节后,对第二卡孔320的波浪形壁面322和第二挂钩部件之间的热融处理,使第二挂钩部件6与底座300固定在一起,使所述整体部件在对应于第二卡孔的位置处沿着铁芯安装孔的轴线方向和垂直于铁芯安装孔的轴线的水平方向同时被限位,并利用波浪形壁面322实现整体部件在对应于第二卡孔的位置处沿着垂直于铁芯安装孔的轴线的水平方向的微调整;也就是说,由于第二卡孔320有波浪形壁面322,第二卡孔320的波浪形壁面322与第二挂钩部件6热融处理后,线圈架(以及整体部件)在对应于第二 卡孔的位置处沿着垂直于铁芯安装孔的轴线的水平方向有微小的移动。
进一步的,本发明的大电流继电器还包括轭铁7,所述轭铁7设有安装脚70,所述轭铁7的安装脚70与所述第二挂钩部件6一起配合在所述第二卡孔320中,且所述轭铁的安装脚70相对于所述第二挂钩部件6更加靠近所述铁芯安装孔的轴线的正下方;所述第二卡孔320的沿着垂直于铁芯安装孔的轴线的水平方向的两个相对的孔壁中的其中一个相对于另一个更加远离所述铁芯安装孔的轴线的正下方。

本发明的一种可调整超行程的大电流继电器,将第一挂钩部件5设计成包括两个朝向相反的挂钩51、52和两个挂钩51、52之间的一个使对应的挂钩能够弹性摆动的第一避让槽53;所述两个挂钩51、52的钩头50分别朝向所述铁芯安装孔的轴线的正下方的两侧;将第二挂钩部件6设计成包括一个钩头60朝向线圈架外的挂钩61和设在挂钩旁边使所述挂钩能够向线圈架内方向弹性摆动的第二避让槽62。本发明的这种结构,在线圈架1压入底座300时,第一挂钩部件5装入第一卡孔310时,第一挂钩部件5的两个钩头50向中间方向变形,第二挂钩部件6装入第二卡孔320时,第二挂钩部件6的钩头60向触点方向变形,从而可以降低装配时线圈架与底座之间的装配难度和解决装配时的塑料异物产生。
本发明的一种可调整超行程的大电流继电器,在第二卡孔320的沿着垂直于铁芯安装孔的轴线的水平方向的两个相对的孔壁中的其中一个还设为波浪形壁面322。本发明的这种结构,通过将第二卡孔320的一侧壁设计成波浪形结构,调整完超行程后对第二挂钩部 件6进行热熔处理,第二挂钩部件6的热熔融物填充波浪形表面322,能够实现整体部件在对应于第二卡孔的位置处沿着铁芯安装孔的轴线方向和垂直于铁芯安装孔的轴线的水平方向同时被限位,同时,波浪形的表面可以增加第二卡孔320与挂钩61的热熔融物的配合面积,增加固定强度。

本发明的一种负载端子带信号监控的大电流继电器,采用了在塑料体92中,在对应于所述两个静簧4的凸部42的周边还分别设有让位区,在两个静簧的凸部分别套接有弹簧95,弹簧95在对应的让位区中被压缩在所述金属导电片65与所述静簧的主体部911之间。本发明的这种结构,利用弹簧95的可变形性,在弹簧95变形后 始终与金属导电片65、静簧的主体部911相接触,从而可以保证信号诊断端子(即金属导电片)与负载端子(即静簧的主体部)之间的可靠连接,进一步保证了诊断信号的传递,从而可以保证***对监测信号的有效读取。
桥式大电流电磁继电器实施例
参见图64至图69所示,本发明的一种桥式大电流电磁继电器,包括外壳2、底座300、安装在底座300上的两个具有刚性特征的静簧4、呈卧式安装在底座300上的线圈201以及匹配在线圈201的附近的衔铁67和轭铁7之间的具有柔性特征的动簧片8;在动簧片8的连接有所述衔铁67的一端还固接具有刚性特征的桥接片78,并使桥接片78的两端分别与两个静簧4相对应;所述每个静簧4上分别设有两个静触点41,所述桥接片78的两端分别设有两个动触点150,且四个动触点150呈水平一字型排列,静簧4上的两个静触点41也呈水平排列,铁芯49的一端设为极面,铁芯49的另一端与轭铁7相固定。
轭铁7为L型,轭铁7的L型的一边为第一部分71,该第一部分71与铁芯49的另一端相固定外,轭铁7的L型的另一边为第二部分72,该第二部分72配置在线圈的旁边(即线圈架的绕线窗口外),本实施例中,轭铁7的第二部分72是配置在线圈201的上面,轭铁7的第二部分72的端头作为轭铁7的刀口用来配合衔铁67。
具有柔性特征的动簧片8也弯成大致L型,动簧片8的L型的一边为第一部分81,该第一部分81与轭铁7的第二部分72相固定,动簧片8的另一边为第二部分82,该第二部分82与衔铁67相固定,使得衔铁67能够以轭铁7的刀口为转轴吸向4的极面。当所述线圈201工作,使衔铁67吸向铁芯49的极面,衔铁67带动动簧片8的第二部分82摆动,动簧片8的第二部分82再带动桥接片78移动,使所述桥接片78的两端与两个静簧点41相接触,所述桥接片78的两端的两个动触点150分别与两个静簧4上的两个静触点41对应相接触。
本实施例中,所述桥接片78的两端的两个动触点150和两个静簧4上的两个静触点41分别设为方形结构。
本实施例中,所述桥接片78的两端的两个动触点150和两个静簧4上的两个静触点41的触点表面分别设为向外凸出的弧面。
本实施例中,所述的两个静簧4分别设在所述桥接片78与所述线圈201之间。
本实施例中,所述的两个静簧4分别对称装在底座300的两侧。
本实施例中,所述底座300中,在对应于桥接片78的背向动触点的一面还装有止挡块85;止挡块85也是两个。本实施例的止挡块85为单独的零件,装在底座300上,当然,止挡块85也可以由底座一体形成。
本实施例中,所述止挡块85中,还装有缓冲垫851。缓冲垫851是用来降低继电器释放时的噪音,继电器释放时,桥接片78会随衔铁67的释放而靠向止挡块85,由于止挡块85有缓冲垫851,可以缓冲桥接片78的撞击力,从而降低撞击产生的噪 声。
本发明的一种桥式大电流电磁继电器,在每个静簧4上分别设有两个静触点41,在所述桥接片78的两端分别设有两个动触点150,且四个动触点150呈一字型排列,当所述线圈201工作而使所述桥接片78的两端与两个静簧4相接触时,所述桥接片78的两端的两个动触点150分别与两个静簧4上的两个静触点41对应相接触。本发明的这种结构,是在每个负载端子(即静簧)上同时设有并列的两个触点,这两个触点实现并连,而在动簧片的桥接片上对应设有的四个触点,并让桥接片上的四个触点分别于负载端子上的两个触点两两对应,两个负载端子(即静簧)则通过桥接片实现串联,双触点在负载端子端接通时,双触点并联使得等效的电阻减半(也相当于电流分流,可提升载流能力),因此在同等电流条件下,功耗量降低至原来的1/2,因此大大降低触点的功耗量,即降低触点处的发热,从而提升产品性能——负载能力更高;两个负载端子借助桥接片串联,实现电流回路的同步双断开也使得出现的电弧能量减半,达到减小触点分断时的燃弧的目的。从另一方面来说,双触点在负载端接通时,双触点起到分流作用,因此单触点的承担的电流为原来的1/2,根据Q=I2RT原理,同等电流条件下,发热量降低至原来的1/4,因此大大降低触点的发热量,从而提升产品性能。
本发明的一种桥式大电流电磁继电器,将桥接片78的两端的两个动触点150和两个静簧4上的两个静触点41分别设为方形结构,以及将桥接片78的两端的两个动触点150和两个静簧4上的两个静触点41的触点表面分别设为向外凸出的弧面。本发明的这种结构,可以利用方形结构和弧形表面的配合使动静触点间的接触为线接触,从而提高动静触点间接触的可靠性。
本发明的一种桥式大电流电磁继电器,在动簧片2的连接有所述衔铁67的一端还固接具有刚性特征的桥接片78,并使桥接片78的两端分别与两个静簧4相对应。本发明的这种结构,使得动簧片2只需承担动簧部件的来回运动的机械疲劳强度而不承担载流能力,而桥接片78只承担载流能力而不承担载抗机械疲劳能力,在具有相同灭弧能力的情况,能随机选择动簧材料而不需要选择特殊的动簧材料,同时负载回路路程更短(电流只流经桥接片78而不经过动簧片2),即更短的路程则有更小的线路电阻,因此,在相同负载(电流)的条件下,发热量会更小。
应可理解的是,本发明不将其应用限制到本说明书提出的部件的详细结构和布置方式。本发明能够具有其他实施方式,并且能够以多种方式实现并且执行。前述变形形式和修改形式落在本发明的范围内。应可理解的是,本说明书公开和限定的本发明延伸到文中和/或附图中提到或明显的两个或两个以上单独特征的所有可替代组合。所有这些不同的组合构成本发明的多个可替代方面。本说明书所述的实施方式说明了已知用于实现本发明的最佳方式,并且将使本领域技术人员能够利用本发明。
