具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1至5所示，本发明提供一种纤维固定器，包括本体1，所述本体1具有沿长度方向贯穿的纤维容纳孔11，所述纤维容纳孔11用于容纳导电纤维22(通常为纤维束)，沿所述本体1的长度方向所述本体1的周向依次布置有第一防脱环12、纤维固定环13、第二防脱环14；所述第一防脱环12和纤维固定环13之间设置有第一应力槽15，所述纤维固定环13和第二防脱环14之间设置有第二应力槽16，所述第一应力槽15、第二应力槽16均用于吸收在挤压所述纤维固定环13产生的形变。
本体1具有沿长度方向贯穿的纤维容纳孔11，纤维容纳孔11用于容纳导电纤维22，沿本体1的长度方向本体1的周向依次布置有第一防脱环12、纤维固定环13、第二防脱环14，第一防脱环12和纤维固定环13之间设置有第一应力槽15，纤维固定环13和第二防脱环14之间设置有第二应力槽16，第一应力槽15、第二应力槽16均用于吸收在挤压纤维固定环13产生的形变，在安装导电纤维22时，导电纤维22从纤维容纳孔11一端穿入并到达纤维容纳孔11的另一端，优选导电纤维22凸出到纤维容纳孔11的另一端的外部，本体1的尾端凸出导电纤维22用于缓冲。
在实际应用中，第二防脱环14远离第二应力槽16的一端延伸出导向端17，导向端17内的纤维容纳孔11呈喇叭状，如图5所示，用于引导导电纤维22的安装，当本体1的内部安装导电纤维22后通过外力挤压纤维固定环13使得纤维固定环13形变朝向纤维容纳孔11轴心内收进而将导电纤维22压紧固定，同时纤维固定环13被挤压形变后产生的形变通过第一应力槽15、第二应力槽16吸收，如图4、图5为导电纤维22压紧固定后的示意图。
本发明还提供了一种轴承电腐蚀防护导电环，包括环状支架3以及盖板4，盖板4能够匹配安装到环状支架3上并共同围成至少一个安装槽32，安装槽32沿环状支架3的径向布置，为增加防电蚀的功能，安装槽32可以设置多个，多个安装槽32优选在环状支架3上均匀布置。
如图6、图7所示，安装槽32能够匹配容纳纤维固定器，其中，安装槽32包括前端槽321、中间槽322以及后端槽323，其中，前端槽321匹配容纳第二防脱环14，中间槽322匹配容纳纤维固定环13，后端槽323匹配容纳第一防脱环12。
具体地，第一防脱环12、第二防脱环14的外径均大于本体1其他部位的外径使得当本体1安装到安装槽32后不允许发生轴向窜动，增加了安装后的牢固性，第一防脱环12和第二防脱环14的外径、形状优选为相同的结构。
进一步地，第一防脱环12、第二防脱环14、第一应力槽15槽底、第二应力槽16槽底的外形均优选为圆柱形结构，纤维固定环13在挤压前为圆柱形结构，被挤压后横截面优选呈多边形。
为了便于装配，第一防脱环12、纤维固定环13、第二防脱环14的端部均为倒角结构。在实际应用中，盖板4与环状支架3的连接方式可采用多种结构，盖板4可以采用螺接、卡接、焊接或铆接等多种结构连接方式固定在环状支架3上。
更进一步地，本发明还提供一种电机，安装有有本发明上述的轴承电腐蚀防护导电环。
如图8、图9、图10、图11、图12所示，在轴承电腐蚀防护导电环中，盖板4朝向环状支架3的一侧延伸出多个呈环形间隔布置的防脱扣41，防脱扣41为弹性结构，多个防脱扣41形成的环形的外径大于环状支架3内孔的内径，优选多个防脱扣41形成的环形的外径略大于环状支架3内孔的内径使得当盖板4装配到环状支架3中时防脱扣41能够弹性卡扣到环状支架3上。环状支架3背向盖板4的一面的内侧具有防脱卡位31，当盖板4装配到环状支架3的过程中，多个防脱扣41能够穿过环状支架3的中心孔并匹配卡扣在防脱卡位31上。
本实施例中，防脱扣41的端部具有坡面411，坡面411用于引导盖板4卡扣到环状支架3中；环状支架3的内圈还设置有防尘环5，导电纤维22朝向环状支架3中心的一端延伸到挡尘环5内侧面的内部，便于与被电腐蚀部件接触并将电荷及时导走。
请参阅图13至15所示，为本发明另一实施例中的纤维固定器，包括：本体1，所 述本体1内部具有沿长度方向设置的纤维容纳孔11，即所述本体1具有中空结构，所述纤维容纳孔11用于容纳导电纤维2。
所述本体1包括防脱部8与固定部7；固定部7、防脱部8分别是中空结构，固定部7和防脱部8内部互相连通形成容纳导电纤维2的纤维容纳孔11。所述防脱部8大致位于本体1的端部，所述固定部7略大致位于本体1的中部。当然，所述防脱部8也可以设置地大致位于所述本体1的中部，固定部7大致临近本体1的中部。
所述固定部7与所述防脱部8组成所述本体1，所述固定部7与所述防脱部8优选为是一体结构。其中，所述防脱部8的外径大于所述固定部7的外径，所述防脱部8可用于与外部的导电环相互连接，用以支撑、固定所述本体1。
所述纤维容纳孔11贯穿所述本体1或所述纤维容纳孔11为所述本体1内的实心孔。示例地，所述纤维容纳孔11至少形成于所述固定部7的内部并延伸至所述本体1的端部；所述纤维容纳孔11可以完全贯穿所述本体1，也可仅是形成于所述本体1中的腔体，但并未贯穿所述本体1。所述的固定部7与所述防脱部8在图示中为圆柱状，在其他的实施例中，也可以是其他的柱体形状。所述本体1利用纤维容纳孔11容置导电纤维，所述本体1具有一定长度，其在轴向上提供径向束缚力，防止纤维束倒伏。
示例地，所述固定部7为圆柱体或多边形柱体。例如多边形柱体，固定部7可以是半开口结构，其截面成U型。所述固定部7受外力后发生形变使得部分所述纤维容纳孔11的内径收缩，用以将所述导电纤维2固定在所述本体1内。通常所述纤维固定器采用金属材质，具有导电性，外力通常采用挤压方式，使得固定部7受压后发生形变，固定部7内部纤维容纳孔11的孔径收缩，以此使得纤维固定在固定部7中。所述固定部7受外力后发生形变后，其截面至少呈多边形。如图16中，圆柱状的固定部7被压后形成六边形的压接面。当然也可以直接挤压固定部7使其变形包覆并固定所述导电纤维2。
本发明中，所述纤维固定器利用其固定部7变形后固定导线纤维，提供了提供轴向束缚力，固定部7紧固导电纤维可防止导电纤维束脱出，使导线纤维更牢固。
具体地，参考图13至15所示，所述防脱部8包括第一防脱环12与第二防脱环14，分别在所述本体1上前后设置。所述固定部7位于所述第一防脱环12与所述第二防脱环14之间。
进一步地，所述防脱部8包括第一防脱部、第二防脱部，两者可以不是环形，也可以是其他形状，可与其他结构固定即可，比如多边形状，或用于卡接、扣接等形状。
在其他的实施例中，可见图17B，所述防脱部8可以仅设有一个，例如仅包括第一防脱环12。
在包括第一防脱部、第二防脱部的实施例中，所述第一防脱环12和所述固定部7之间设置有第一应力槽15，所述固定部7和第二防脱环14之间设置有第二应力槽16，所述第一应力槽15、第二应力槽16(即吸能槽)均用于吸收在挤压所述固定部产生的形变。
本发明通过在本体1上设计第一防脱环12、固定部7、第二防脱环14，大大提高了纤维固定器在安装槽9中的稳定性，且便于装配，提高了装配效率。
更进一步地，固定部7和防脱部8之间设置吸能槽，减小产品变型，翘曲，降低连接处断裂风险，使剪切向力转换为前后延伸力。在一可选的实施例中，所述第一应力槽15与第二应力槽16的长度范围为4mm-4.2mm。当然也可以根据纤维固定器的尺寸要求进行相应的扩大与缩小前述长度范围。
为了防止纤维损伤脱落，纤维固定器的开口端还设有R角。在一种实施例中，所述本体1的开口端具有R角；所述导电纤维2自所述本体1的开口端向外延伸，见图2中所示的开口位置处(上方位置)。在又一实施例中，所述第二防脱环12位于所述本体1的前端，所述第二防脱环12的开口端具有R角，见图15所示(上方位置)。简言之，导电纤维2延伸出纤维固定器的位置开设R角。相比于传统的C角，C角为两条之间形成的钝角，C角容易使得纤维发生脱落，R角可防止纤维损伤脱落。
请参阅图17，所述的纤维固定器，还包括导电纤维2，所述纤维容纳孔11贯穿所述本体1。所述导电纤维2的至少一端沿所述本体1的长度向外延伸；在图17中，导电纤维2延伸出所述纤维固定器的前端与后端。在其他实施例中，所述导电纤维2可仅延伸出所述纤维固定器的前端(图17的上部)。
所述纤维固定器的本体1具有导电性，导电纤维2也具有导电性，可以通过两者的导电性防止导电环被腐蚀。具体将结合轴承电腐蚀防护导电环、电机进行描述。
请参阅图8、图18、图19所示，本发明还提供一种轴承电腐蚀防护导电环(或称导电环)，包括环状支架3以及外壳，外壳和环状支架3能够采用多种装配结构，能够适用于多种应用场景，实用性强。所述外壳能够匹配安装到所述环状支架3上，所述环状支架3上设有至少一个安装槽9，所述安装槽9用于固定所述纤维固定器，所述纤维固定器嵌套在安装槽9中。
图示中，所述安装槽9设有多个，图中设有12个；分别沿所述环状支架3的圆周布 置，使得纤维伸出到纤维固定器内部；所述纤维固定器的轴向与所述环状支架3的径向大致相同。所述纤维固定器固定的导电纤维2指向所述环状支架3的轴心。
所述安装槽9包括适配于所述纤维固定器的固定部7的第一凹槽91，以及适配于所述纤维固定器的防脱部8的第二凹槽92。所述第二凹槽92的直径略大于所述第一凹槽91的直径。与前文的前端槽321、后端槽323相似。
当纤维固定器固定在环状支架3上时，第二凹槽92由于直径略大于第一凹槽91，使得纤维固定器的防脱部8合在第二凹槽92部分中，并且可以避免纤维固定器整体在导电环径向的移动。
进一步地，所述纤维固定器的防脱部8的上表面略高于所述环状支架3，当纤维固定器固定在环状支架3上时，纤维固定器的防脱部8的表面略高于环状支架3的上表面，防脱部8的圆直径最大部分与环状支架3的安装槽9形成一个类似于卡扣型式，抱住端子套，所述防脱部8与所述外壳紧密接触，可以防止在运动移动过程中脱落，且防脱部8上部凸出于环状支架3，可在装配时可以充分接触所述外壳达到电导通的目的。
更进一步地，环状支架3可以是多层的，可以在一个轴承电腐蚀防护导电环内设置多个环状支架3。
装配后，所述纤维固定器上固定有导电纤维2，所述导电纤维2的末端与所述外壳过盈接触，所述纤维固定器的末端与所述外壳过盈接触。
如图19、图20，纤维固定器的长度方向指向导电环的圆心位置，使得纤维固定器布置在环状支架3内部时，导电纤维2的长度方向与导电环的径向方向保持一致，并且导电纤维2的末端也指向导电环的圆心位置。
所述轴承电腐蚀防护导电环装在电机上后，导电环内部布置电机的输出轴，导电纤维2的末端接触电机的输出轴，导电纤维2的前端与电机轴过盈接触，导电纤维2的尾端与金属的外壳过盈接触，并且纤维固定器与导电纤维2为紧密接触，纤维固定器与电机的外壳形成紧密接触，外壳与电机外表面为过盈接触。因此，电机轴与导电纤维2、纤维固定器、电机外壳形成一个低电阻的导通回路，当电机使用时电机轴上产生的电荷会很容易地被导电环导通至电机的外壳，电荷不会在电机轴承之间堆积形成高电压势，从而降低了电腐蚀的风险，加长了电机轴承的寿命。否则，电荷在轴承堆积，形成电腐蚀。
本发明还提供一种电机，通过在环状支架3和外壳之间设置安装槽9并将导电纤维2通过与安装槽9外形匹配的纤维固定器固定，大大提高了装配的便捷性，且安装工序少， 加工和装配简单，也有利于批量生产。
具体的，所述电机包括外壳，外壳内设有电机及设于轴承电腐蚀防护导电环上的导电纤维2，所述电机的输出轴安装于所述轴承电腐蚀防护导电环内，所述导电纤维2的前端与所述电机轴过盈接触，所述导电纤维2的尾端与所述外壳过盈接触，所述纤维固定器的本体1与所述外壳过盈接触，所述外壳与所述电机过盈接触；其中外壳与所述外壳相连接，皆为金属，具有导电性；所述纤维固定器的本体1、所述外壳均具有导电性。电机轴与导电纤维2、纤维固定器、电机外壳形成一个低电阻的导通回路，当电机使用时电机轴上产生的电荷会很容易的被导电环导通至电机的外壳，电荷不会在电机轴承之间堆积形成高电压势，从而降低了电腐蚀的风险，加长了电机轴承的寿命；同时为轴承电腐蚀防护导电环提供了一种新的结构方案。
以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
