    • To retain end portions (10,11) of armature conductors in slots (6, 37) formed in radially projecting lugs (5) of armature segments (2) of a commutator (1), the side walls of the slots are formed with a deviation from a plane surface, for example by a recess (7) or an inwardly extending projection (38), and the end portions (10, 11) of the windings are then placed in the slot and deformed under punch or stamping pressure to form, together with the recess or the region adjacent the projection, an interfitting projection-and-recess connection which will withstand high centrifugal forces, and prevent loosening of the connection under conditions of shock, vibration, high temperatures and temperature changes, to make the connection particularly suitable for installation in mobile, typically automotive dynamo electric machines. The apparatus to make the connection includes a punch press which can either sequentially or simultaneously place one or two end portions (10, 11) of conductors into the slots (6, 37) of the lugs. For further clamping, the edges of the lugs adjacent the walls of the slots can be deformed, for example by shearing, to overlap the uppermost end portion (11) of the conductors.
    • 为了将电枢导体的端部(10,11)保持在形成在换向器(1)的电枢段(2)的径向突出的凸耳(5)中的槽(6,37)中,槽的侧壁形成有 例如通过凹部(7)或向内延伸的突起(38)与平面的偏离,然后将绕组的端部(10,11)放置在槽中并在冲压或冲压压力下变形以形成 与凹部或邻近突起的区域一起,形成能够承受高离心力的相互配合的突出和凹陷连接,并且在冲击,振动,高温和温度变化的条件下防止连接的松动,从而使连接 特别适合安装在移动电话,通常是汽车发电机。 用于制造连接的装置包括冲压机,其可以顺序地或同时地将导体的一个或两个端部(10,11)放置到凸耳的槽(6,37)中。 为了进一步夹紧,邻近狭缝壁的凸耳的边缘可以例如通过剪切而变形,以与导体的最上端部分(11)重叠。
