Preferably, the cap mouth direction of described the 3rd waterproof sealing hoop waterproof insulation end cap tilts, and the aperture of the 3rd waterproof seal ring is less than cable diameter.
By above-mentioned setting, the diameter of the 3rd waterproof seal ring is less, in the time that cable inserts, the 3rd waterproof seal ring is due to the outside support of toughness meeting of its elastomeric material and along with the insertion of cable turns down to inside, now there is the trend of contraction due to the 3rd waterproof seal ring, make to hold between itself and cable tighter, it tilts to cap mouth simultaneously, and can ensure cable insertion time, the 3rd waterproof seal ring can excessively not turn down and cause seal failure.
Preferably, described puncture blade is four angle of throat sheets.
By above-mentioned setting, puncture blade easily punctures cable sheath also and conductor contact, and the effect that is fixed and clamped is more obvious, more firmly practical.
Preferably, the upper edge of described rainhat is provided with the eaves that keeps off the rain.
By above-mentioned setting, the eaves that keeps off the rain can be kept out the part rainwater directly falling, and plays certain effect of keeping off the rain, and prevents that rainwater from flowing in rainhat.
In sum, the beneficial effect that the utility model in contrast to prior art is: rainwater easily infiltrates from the gap of rainhat when rainy, cause the rainwater can be along cable shafts to flowing in termination, here the waterproof seal ring extending out by waterproof insulation end cap inner ring surface plays the effect of axial seal waterproof, cable penetrates in waterproof insulation end cap, waterproof seal ring wraps cable, seals up axial gap, makes the waterproof sealing of waterproof insulation end cap better.
