    • An electric brake (10) comprises an actuator module (27) including a module housing (36), a reciprocating ram (26), and an electric motor (31) operatively connected to the reciprocating ram (26) for selectively extending and retracting the reciprocating ram (26) with respect to the module housing (36). The ram (26) has an inner portion of non-circular cross-section and an outer portion of circular cross-sectional, and the housing (36) has a guideway (58) for the ram (26), which guideway (58) has an inner portion (62) of non-circular cross-section for interacting with the inner portion of the ram (26) to prevent rotation of the inner portion of the ram (26), and an forward portion of circular cross-sectional (65). The actuator module (27) can be equipped with a bi-stable holding brake (34) having a first state permitting at least retraction of the ram (26) and a second state preventing at least retraction of the ram (26). The invention also provides an electrical connector (43) having an insertion direction for connecting to a mating connector, which insertion direction is parallel or perpendicular to the movement direction of the ram (26). Also provided is a cable conduit (29) including a generally arcuate-shaped channel, a plurality of module connectors (43) disposed along the length of the channel for connecting to respective actuator modules (27) of an electric brake (10), a common connector disposed along the length of the channel for connecting to an external cable, and electrical wiring in the channel for connecting the common connector to each of the module connectors. In addition, the brake head (18) can have plural radially outwardly opening slots (75) at radially outer sides thereof for receiving the actuator modules (27).
    • 电动制动器(10)包括包括模块壳体(36),往复压头(26)和可操作地连接到往复压头(26)的电动机(31)的致动器模块(27),用于选择性地延伸和缩回 往复冲头(26)相对于模块壳体(36)。 冲头(26)具有非圆形横截面的内部部分和圆形横截面的外部部分,并且壳体(36)具有用于冲头(26)的导轨(58),该导轨(58) 具有非圆形横截面的内部部分(62),用于与冲头(26)的内部部分相互作用以防止冲头(26)的内部部分的旋转,以及圆形横截面的前部部分 65)。 致动器模块(27)可以配备有双稳态保持制动器(34),该双稳态保持制动器具有允许至少缩回撞锤(26)的第一状态和至少防止撞锤(26)缩回的第二状态。 本发明还提供一种电连接器(43),其具有用于连接到配合连接器的插入方向,该插入方向平行于或垂直于撞锤(26)的运动方向。 还提供了一种电缆导管(29),其包括大致弓形的通道,沿着通道的长度布置的多个模块连接器(43),用于连接到电制动器(10)的相应致动器模块(27), 沿通道的长度布置的用于连接到外部电缆的公共连接器,以及用于将公共连接器连接到每个模块连接器的通道中的电线。 另外,制动头(18)可以在其径向外侧具有多个径向向外开口槽(75),用于接收致动器模块(27)。
