The axially loaded component 41(exterior cover sheets or Kafra fiber of optical cable 4) individually bring out to be sheathed on outside first step portion 11,
Fibre core 42 to be connected is passed through in protecting tube 1, by the way that pressure pipe 2 to be sheathed on outside first step portion 11, to the axially loaded of optical cable 4
Component 41 is fixed, to improve axial strength；
It should be noted that Kafra fiber is inside ordinary optical cable 4 for bearing the stressed member 41 of axial force, outside
Protective layer is that the surrounding layer of 4 outside of optical cable is wrapped in first step after can cutting off protective layer with scissors in actual operation again
Outside portion 11.
As shown in figure 4, in the present embodiment, the fixture block 12 axially extended is fixed on the outer wall in first step portion 11,
The section of fixture block 12 is triangle, the card slot 21 being slidably matched with fixture block 12 is offered in pressure pipe 2, by 41 sets of axially loaded component
After outside first step portion 11, pressure pipe 2 is moved inward, when being moved at fixture block 12, continues inwardly firmly to squeeze, along card
The inclined-plane of block 12 is mobile, fixes until card slot 21 is buckled in and is realized outside fixture block 12, is fallen off with being better protected from pressure pipe 2；In addition, being
It further increases assembly efficiency, offers the guiding axially extended in the two sides of fixture block 12 on the outer wall in first step portion 11
Slot 13 is connected with the guide rail 22 being slidably matched with guide groove 13 on the inner wall of pressure pipe 2, by guide rail 22 along guide groove 13 to
