Though to copper be the base cable this be not problem usually, fiber optic cables are more responsive to bending, particularly, than be easier to the damage.Therefore, should be understood that by the system that makes and to realize in the mode that reduces the cable bending that shown in Figure 24 A and 24D, this makes that such structure is very desirable and is used with fiber optic cables.
Once more, in the exemplary-dimensions that is used for this embodiment shown in the table 1.
Those skilled in the art understand obviously and can make various changes and modifications.To significantly these variations and revise and to be considered to drop on the present invention as above in the broadly described scope and spirit of institute of those skilled in the art.
Therefore, for example can revise the location in hole 6 and make that in use hole 6 is comprised in the air groove 15, thereby anti-sealing enters the housing between hole 6 and the cable 37.But this is not essential, because this moment is than being easier to provide waterproof sealing.
