[0036]图4是图示制造用于产生光纤电缆总成10的分界部分26的光纤电缆12所需要的步骤的示意图。 [0036] FIG. 4 is a schematic diagram showing the manufacturing step of the fiber optic cable assembly 10 boundary portion 26 of the fiber optic cable 12 is required to generate. 通过分离工具等将光纤电缆12上的外护罩24移除后退到标记为A的点。 By separating tool or the like to remove the optical fiber cable 24 on the outer shroud 12 back to the point labeled A. 然后,还使用电缆分离工具等沿着光纤电缆12的一侧将材料18移除后退到标记B。 Then, the separating tool is also possible to use cables and the like along one side of the optical fiber cable 12 is removed the material 18 is retracted to mark B. 随后剥掉(将参考图5更详细地描述)和移除材料18,仅留下A减去B长度的暴露的短截材料18。 Subsequently stripped (5 will be described in more detail with reference to FIG) and removal of material 18, leaving only the exposed material A and B minus the length of the stub 18. 然后,在电缆的一侧上将材料18中的短截移除后退到标记A,仅在电缆底侧留下延伸到点B的材料18。 Then, on the side of the material in the stub 18 of the cable to the back of removal of marker A, leaving only the material 18 to point B extending in the bottom side of the cable. 此举有效地在材料18的电缆的一侧上留出窗口18a,粘合剂34可放置在所述窗口18a中。 This effectively leaving a window 18a on one side of the cable material 18, the adhesive 34 may be placed in the window 18a. 然后在标记C处切割掉加强构件16,并且最后插入保护管28,并且保护管28在光纤14上滑动到标记D的起点。 Then cut off at mark C reinforcing member 16, and finally inserted into the protective tube 28 and protective tube 28 is slid to the mark D in the fiber 14 starting point. 切割的加强构件16(未图示)的另一半在后续阶段中引入具有加强构件16的分叉配置中,以为分界部分26提供更多的强度(此将参考图5和图7描述)。 Cutting the reinforcing member 16 (not shown) is introduced into the other half in the subsequent stage bifurcated configuration having a reinforcing member 16, the boundary portion 26 that provides additional strength (herein with reference to FIG. 5 and FIG. 7 below). 随后提供光纤锁定配置来将光纤14紧固到位。 Then providing an optical fiber configured to lock the optical fiber 14 firmly in place. 此将关于图5和图7更详细地描述。 This will be described with respect to FIGS. 5 and 7 in more detail.

[0037]图5a图示如图4所示的移除到标记A的外护罩24以及如图4所示的已分离到标记B的材料18。 [0037] As shown in FIG. 5a illustrates the removal of the outer shroud 24 labeled A in FIG. 4 and FIG separated material to mark B shown in 184. 在图5b中,已移除材料18并在点B处留下材料18。 In Figure 5b, the material 18 has been removed and leaving a material point B 18. 进一步地,已移除材料18的上半部分,仅留下窗口18a,如图5b中可见。 Further, the removed upper half of the material 18, leaving only a window 18a, is visible in Figure 5b.

[0038]在图5c中,保护管28在材料18上滑动,并随后如图5d所示,涂覆呈粘合剂34形式的光纤锁定配置。 [0038] In Figure 5c, the protective tube 28 to slide on the material 18, and then as shown in FIG 5D, the coated optical fiber as a binder in the form locking 34 configuration. 保护管28并非一直滑动到窗口18a和外护罩24的交叉点,而是滑动到窗口18a上的中点处。 The protective tube 28 are not always at the midpoint of the sliding window 18a and the outer shroud 24 of intersection, but the sliding window 18a. 这是为了确保将粘合剂涂覆到光纤14和保护管28两者上,以抑制光纤14、保护管28和窗口18a的运动。 This is to ensure that the adhesive is applied to both the fiber 14 and protective tube 28, to suppress the optical fiber 14, tube 28 and the window 18a sports protection. 粘合剂34通过窗口18a和加强构件16—起将保护管28和光纤14结合到光纤电缆12。 Adhesive 34 through the window 18a and the reinforcing member 28 16- Since the protective tube 14 and the optical fiber coupled to the optical fiber cable 12. 在示范性实施方式中,此配置使光纤连接器22免受光纤电缆12的影响,例如,因为光纤连接器22仅能经受有限量的力。 In an exemplary embodiment, the configuration that the fiber optic connector 22 of fiber optic cable 12 from the effects of, e.g., because the optical fiber connector 22 can only withstand a limited amount of force. 进一步地,此配置抑制光纤14影响连接器22的端面的配合。 Further, the configuration of the optical fiber 14 to suppress the influence mating end of connector 22. 如果过多的力施加到光纤14(例如,大于连接器弹簧弹力的力,例如两(2)镑的力),那么连接器22的端面将失去实体接触。 If too much force is applied to the optical fiber 14 (e.g., a force greater than the spring force of the connector, for example, two (2) pounds of force), the end faces of the connector 22 lose physical contact.

[0039]如图5e所示,经切割的(见图4)光纤电缆12的加强构件16与分叉部分的加强构件16的末端重叠,以使得来自两部分的加强构件16彼此重叠。 [0039] As shown in FIG 5E, the cut (see FIG. 4) reinforcing member reinforcing member 16 and the bifurcated portion 12 of the fiber optic cable 16 of the overlapping ends, so that the reinforcing member 16 from the two parts overlap each other. 在图5e中,存在沿着分界部分26的一部分延行的来自每个部分的两个加强构件16。 In Figure 5e, the presence of a boundary portion extending along a portion of line 26 from each of the two portions of the reinforcing member 16.
