Holding tank end is set for opening, accommodates trench bottom and is provided with projection and supplies the reciprocating opening of projection, projection is consolidated by spring
It is scheduled on receiving trench bottom.
Middle tube body of the present invention is metal material, in use, the crust of cable is peeled off, is then inserted into body, cable
After end touches projection, projection moves into holding tank, while the ball in holding tank is moved outward, and then holding tank end
The ball in portion protrudes from the openend of holding tank directly and conductive cable contacts, plays a part of fixed cable；Now, traction is pulled
Rope, band is shut down, and expandable sealant is flowed into body from embedding mouth, then heats heat-shrinkable T bush, is received in heat-shrinkable T bush
Tightly while on cable and oversheath, expandable sealant expanded by heating, by space sealing in body, while fixed cable is played
Effect.
Further, the projection is the column structure of diameter change, minimum with spring junction diameter, free to projection
End diameter becomes larger and projection outer surface smoother transition, the structure can make the reciprocating motion of projection more convenient, reduces fortune
Dynamic resistance.
Further, in order to preferably fix cable end, the open-ended of the holding tank protrudes from inboard wall of tube body.
Preferably, the screen layer is foil shielding layer.
Further, the oversheath includes the component of following parts by weight：30 parts of ethylene propylene diene rubber, neoprene 36
Part, 20 parts of aluminium hydroxide, stearic acid 10-15 parts, paraffin 3-5 parts, antimony oxide 3-5 parts, stannous chloride 1-2 parts, zinc oxide
