Description

脱扣器空程调节装置 技术领域
本发明涉及低压电器领域，更具体地涉及一种脱扣器空程调节装置。
背景技术
断路器是一种不仅可以接通和分断正常负载电流，而且可以分断短路电流和过载电流(统称为故障电流)的开关电器。它在电路中主要起短路保护和过载保护的作用。有时，断路器还具有欠电压保护和远距离分断电源等功能。
脱扣器是断路器的重要组成部分。当断路器的主回路中出现过载电流或短路电流(即，故障电流)时，脱扣器的执行端在故障电流的作用下，推顶断路器的牵引杆使断路器分断。
目前，由热磁脱扣器控制过载电流进行线路保护的热可调断路器通常具有主牵引杆和热可调牵引杆两根独立的牵引杆。当电流过载一定时间时，热磁脱扣器的双金属元件弯曲到一定程度，带动脱扣器的执行端推动热可调牵引杆动作。热可调牵引杆的动作信号通过传动装置传递到主牵引杆，以控制断路器分断。也就是说，脱扣动作信号必须要通过中间转换杆或其他中间转换装置才能驱动主牵引杆控制断路器分断。

在根据本发明实施例的脱扣器空程调节装置中，上述直角梯形的下底面、上述直角梯形的斜边面、以及上述直角梯形的上底面分别形成脱扣器的执行端的三个动作空程档位。

在根据本发明实施例的脱扣器空程调节装置中，可调牵引杆设置有牵引杆伸出端，旋钮伸出端穿过牵引杆伸出端上的通槽。
在根据本发明实施例的脱扣器空程调节装置中，调节部件具有前后对称的结构。
在根据本发明实施例的脱扣器空程调节装置中，支架具有立柱，该立柱上设置有中空的凸出部，该中空的凸出部插入基座的凹槽中，从而在调节部件的宽度方向上实现调节部件与基座的紧配合。

具体实施方式
下面将详细描述本发明的各个方面的特征和示例性实施例。在下面的详细描述中，提出了许多具体细节，以便提供对本发明的全面理解。但是，对于本领域技术人员来说很明显的是，本发明可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示 出本发明的示例来提供对本发明的更好的理解。本发明决不限于下面所提出的任何具体配置和算法，而是在不脱离本发明的精神的前提下覆盖了元素、部件和算法的任何修改、替换和改进。在附图和下面的描述中，没有示出公知的结构和技术，以便避免对本发明造成不必要的模糊。
图1是示出安装在断路器中的根据本发明第一实施例的脱扣器空程调节装置的斜视局部图。如图1所示，根据本发明第一实施例的脱扣器空程调节装置包括调节部件11、以及可调牵引杆12；可调牵引杆12可滑动地套装在断路器的牵引杆21上；可调牵引杆12在靠近脱扣器31一侧的表面121上具有厚度差；当用户对调节部件11进行操作时，调节部件11驱动可调牵引杆12在断路器的牵引杆21上滑动，从而改变脱扣器31的执行端的动作空程。
在图1所示的脱扣器空程调节装置中，由于可调牵引杆12可滑动地套装在断路器的牵引杆21上，所以可调牵引杆12与断路器的牵引杆21同步旋转，从而可以减少中间转换环节，无过渡传递时间。这样，在对产品升级改进时，变化的零部件数量相对较少，对内部附件的接口无影响。
图2是示出根据本发明第一实施例的调节部件11的轴测视图。如图2所示，调节部件11包括支架111、压环112、以及旋钮113；旋钮113的旋钮伸出端113-2穿过支架111的上伸出端；旋钮113由压环112安装到支架111上；并且旋钮113的旋钮伸出端113-2相对于旋钮113的主体113-1偏心。
在一些实施例中，如图2所示，支架111的靠近旋钮113的旋钮伸出端113-2的位置处，固定设置有例如圆形托盘114，以对旋钮113的旋钮伸出端113-2形成支撑，从而避免支架111的上伸出端由于用户对旋钮113的过度用力而变形或者折断。
在一些实施例中，如图2所示，支架111具有两根立柱，该两根立柱的下端是例如，扁形结构；支架111的两根立柱之间通过连接板连接，以增加支架111的强度；支架111的两根立柱上对称地设置有外凸半圆形内中空的凸起111-1，底端设置有卡紧凹槽111-2。
图3是示出安装图1和图2所示的脱扣器空程调节装置的断路器基座 的斜视图。如图3所示，302为调节部件11的安装槽，限位凸起303为调节部件11限位。
结合图2和图3可以看出，通过调节部件11中的支架111的立柱与断路器基座上的安装槽302的配合，可以将调节部件11可拆卸地安装到断路器基座上；支架111的两根立柱上的中空的凸起111-1使支架111在宽度方向上具有压缩量，从而可以保证调节部件11与断路器基座在其宽度方向上实现紧配合；调节部件11的两根立柱上的卡紧凹槽111-2与断路器基座上的限位凸起303配合在高度方向实现调节部件11的限位，相互配合的凹槽和凸起为例如等边梯形，这样有利于支架111在断路器基座上的卡紧。
在上进线下出线和下进线下出线两种断路器基座上中，调节部件11的支架111的安装腔位不同。为了使根据本发明第一实施例的脱扣器空程调节装置在上述两种断路器基座中通用，可以将调节部件11设置为前后对称的结构。图4是示出根据本发明第一实施例的调节部件11的俯视图。如图4所示，调节部件11具有前后对称的结构，A-A为对称面。由于调节部件11具有前后对称的结构，所以调节部件11可以分别以正反两个方向安装到上进线下出线和下进线下出线两种断路器基座上，实现根据本发明第一实施例的脱扣器空程调节装置在上述两种断路器基座上的通用，从而提高标准化系数、降低生产成本和管理成本。
图5是示出根据本发明实施例的调节部件11的剖视图。如图5所示，113-1为旋钮113的主体，113-2为旋钮113的旋钮伸出端，并且旋钮伸出端113-2相对于旋钮113的主体113-1偏心。
图6是示出根据本发明实施例的可调牵引杆13和断路器的牵引杆21的分解轴测视图。如图6所示，牵引杆21设置有2个凹槽211和212。可调牵引杆12的主体为薄壁倒V形，V形开口端向内折边分别为131和132，可调牵引杆12靠近脱扣器31一侧的表面122上设置有截面为直角梯形的凸起132-2。可调牵引杆12的主体右侧设置有带有通槽的牵引杆伸出端。
结合图1和图6可以看出，调节部件11中的旋钮伸出端113-2穿过可调牵引杆12的牵引杆伸出端上的通槽，可调牵引杆12可滑动地套装到牵 引杆21上，可调牵引杆12的内折边131和132与牵引杆21的凹槽211和212配合(即，可调牵引杆12通过卡扣连接方式卡接在牵引杆21上的滑动凹槽中)，可调牵引杆12可以在牵引杆21上滑动。转动旋钮113通过偏心的旋钮伸出端113-2驱动可调牵引杆12在牵引杆21上滑动。
在上述实施例中，可调牵引杆21的主体设置为倒V形，可以节省断路器的内部空间(旋转时)，从而可以增加根据本发明第一实施例的脱扣器空程调节装置的配置灵活性。
在上述实施例中，脱扣器空程调节装置具有三个可调档位，对应的脱扣空程分别为脱扣器31的执行端到可调牵引杆12的直角梯形凸起122-2的梯形下底面、梯形的斜面、梯形的上底面，其中，梯形下底面与可调牵引杆12的倒V形主体的一侧共面。这里，由于形成可调牵引杆12在靠近脱扣器31一侧的表面121上的厚度差的凸出部的截面为直角梯形，所以脱扣器空程调节装置的最大和最小档稳定，易于保证批量的一致性。
在上述实施例中，脱扣器31的执行端与可调牵引杆13的距离发生变化，使机构脱扣的脱扣器动作空程不同，而脱扣器31的执行端的动作空程由电流值决定，因而包括上述脱扣器空程调节装置的断路器具备热可调功能。
图7是示出安装在断路器中的根据本发明第二实施例的脱扣器空程调节装置的轴测视局部图。从图7可以看出，在根据本发明第二实施例的脱扣器空程调节装置中，除了调节部件11b以外，其他部分与根据本发明第一实施例的脱扣器空程调节装置相同。
图8是示出根据本发明第二实施例的调节部件11b的轴测分解视图。如图8所示，调节部件11b包括支架111b、盖板115、旋钮113b、以及螺钉116；支架111b的下端设置有两个中空的凸起111b-1；盖板115上设置有两个长孔115-1；支架111b上端的两个凸起111b-4分别穿过盖板115上的两个长孔115-1；盖板115由螺钉116紧固在支架111b上；旋钮113b为偏心结构，旋钮113b的主体靠近旋钮113b的旋钮伸出端113b-2的位置设置有两个圆盘113b-3、113b-4，这两个圆盘中间是稍细的圆柱113b-5；两个圆盘113b-3、113b-4卡入盖板115的弧形缺口115-2；弧形缺口115-2两侧分别设置有凸起115-3，这两个凸起之间的距离小于圆柱113b-5的直 径，使得旋钮113b在挤入弧形缺口115-2后，在断路器的牵引杆21的动作引起的振动中不易从支架111b上脱出；圆盘113b-3上设置有凸起，该凸起在旋钮113b在盖板115上转动的过程中会碰到盖板115上的两个凸起；盖板115上的两个凸起作为旋钮113b的两个极限转动位置，以控制可调牵引杆12在断路器的牵引杆21上的滑动量。
图9是示出安装图7和图8所示的脱扣器空程调节装置的断路器基座的轴测视图。结合图8和图9可以看出，调节部件11b的支架111b纵向插入到断路器基座上的安装槽302b中；支架111b的另一伸出端111b-3对应断路器基座上的凹槽303b；伸出端111b-3下面的凸起沉入凹槽303b，实现支架111b在断路器基座上的定位；伸出端111b-3上设置有孔，以便通过诸如螺钉之类的紧固件将支架111b与断路器基座固定；由于伸出端111b-3上设置有凸起，所以用于固定诸如螺钉之类的紧固件的螺纹孔可以更长，螺纹安装可以更加可靠；这里，支架111b在高度方向的限位由伸出端111b-3上方平板的下表面与断路器基座的凹槽303b所在的上平面实现的；支架111b两侧的中空的凸起111b-1具有弹性，可以实现与断路器基座上的安装槽的紧配合。
图10是示出安装在断路器中的根据本发明第三实施例的脱扣器空程调节装置的轴测分解视图。图11是示出根据本发明第三实施例的调节部件11c(图中未示出)的轴测分解视图。类似地，在根据本发明第三实施例的脱扣器空程调节装置中，除了调节部件11c以外，其他部分与根据本发明第一实施例的脱扣器空程调节装置相同。在图10和图11中，50为翻盖、40为大盖，401为大盖开孔，堵盖402和旋钮113c安装到大盖40上。
图12是示出图10所示的大盖的局部视图。图13是示出安装在图11所示的调节部件11c中的旋钮的轴测视图。如图12所示，大盖开孔401由大圆孔和小长圆孔组成。如图13所示，旋钮113c的主体上设置有小圆盘113c-3和大圆盘113c-4；当旋钮113c被安装到大盖40上时，大盖40上的大圆孔为大圆盘113c-4让位；旋钮113c的两个圆盘中间的圆柱113c-5滑入大盖40上的小长圆孔中；堵盖402堵住大盖开孔401上的大圆孔；堵盖 402底部设置有凸起，该凸起可以卡住大盖开孔401内侧的凸起，使堵盖402不能上下滑出；旋钮小圆盘113c-3上设置有凸起；旋钮113c在转动过程中，小圆盘113c-3上的凸起会碰到大盖40上的两个凸起；大盖40上的这两个凸起作为旋钮113c的两个极限转动位置。
本发明可以以其他的具体形式实现，而不脱离其精神和本质特征。例如，特定实施例中所描述的算法可以被修改，而系统体系结构并不脱离本发明的基本精神。因此，当前的实施例在所有方面都被看作是示例性的而非限定性的，本发明的范围由所附权利要求而非上述描述定义，并且，落入权利要求的含义和等同物的范围内的全部改变从而都被包括在本发明的范围之中。
