用于具有换向器的电机的电刷架以及用于所述电刷架的保护装置
摘要：
本发明涉及用于具有换向器的电机的电刷架（1）以及用于所述电刷架（1）的保护装置（PD）。电刷架（1）包括，具有接收该换向器的开口（3）的支撑结构（2,6），环绕开口（3）设有电刷安装结构（4），电刷（5）安装于电刷安装结构（4）内。在支撑结构（2,6）内设有连接电刷（5）至外部电源端子的电性连接路径（7）。沿至少所述连接路径之一设有保护装置（PD），其包括有弹性的可变形的并且导电的机械且电性连接于两导电构件（17,18）之间的叶片（40），叶片（40）在一端处于大体上固定的方式(40b,18)并且在另一端具有热可熔的连接(40a,17)，并且具有有弹性的趋向于破坏该在所述另一端的连接(40a,17)的预加载。
摘要（英）：

The invention relates to an electric brush carrier (1) with a commutator, and a protective device (PD) for the electric brush carrier. The electric brush carrier (1) comprises a support structure (2, 6) with an opening (3) for receiving the commutator, wherein an electric brush installation structure (4) is arranged surrounding the opening (3), an electric brush is installed in the electric brush installation structure (4). Electric connection paths (7) for connecting the electric brush (5) to external power supply terminals, are arranged in the support structure (2, 6). The protective device (PD) is arranged along at least one of the connection paths, and comprises elastic, transformable and conductive machinery, and a blade (40) electrically connected between two conductive components (17, 18), wherein the blade (40) is in a approximately fixed manner (40b, 18) at one end and comprises thermal-fusible connection (40a, 17) at the other end, and the blade comprises preload which is elastic and is intended to destroy the connection (40a, 17) at the other end.
