Abstract
A cable sheath waterproof plastic sealing element is composed of an outer sleeve (1) and a sealing part. At least one end of the outer sleeve is provided with the sealing part which is composed of a rubber sealing layer, a supporting element and a fixing ring. The rubber sealing layer (2) and the supporting element (2-1) are provided with cable holes (3) to be passed through; matched with the thread mouth of the outer sleeve, the fixing ring is used for fixing the rubber sealing layer and the supporting element; and a plurality of cable holes are cut on the rubber sealing layer and the supporting element. The guidance and protection device for the extension of electric or optical cables and the like into a building form a trench is concise and reliable in structure, convenient in installation and far superior to products of the prior art in sealing effect, avoids that groundwater enters an underground structure along the electric cable, and can satisfy the water tight (also insect prevention and rat proof) performance requirements of various engineering structures.
Description
Technical field
The present invention relates to the connector and the protective device of cables such as cable and optical cable.
Background technology
Cable (comprising cable and optical cable etc.) enters building from trench need adopt sheath when (comprising the hypogee), especially the seal of water-tight insect protected is used in the guide cable optical cable, the passage that needs isolating seal trench and building again, existing similar water string, as CN201025668 cable waterproof sleeve pipe, be provided with rubber sealing sheet in union body, this rubber sealing sheet is provided with cable aperture.In union body, be provided with rubber sealing sheet, and in rubber sealing sheet, be provided with cable aperture, but the cable aperture that passes through of current supply cable not only during use, be convenient to installation, but and the cable aperture place passed through of rubber sealing sheet driving fit cable, avoided underground water to enter in the underground structure, also can in union body, be provided with caulking gum layer and cover plate along cable.Yet existing water string lacks in sealing to some extent for a long time, structurally needs to improve.
Summary of the invention
The present invention seeks to: propose a kind of cable and optical cable enters building from trench guiding and protective device; especially the seal connector and the protective device of the waterproof insect protected of cable such as cable and optical cable; a kind of reliable in structure is especially proposed; easy for installation, good sealing effect water-proof plastic sealing element for cable sheath.
Technical solution of the present invention is: water-proof plastic sealing element for cable sheath, by outer tube 1, at least one end is provided with seal member on outer tube, described seal member comprises that rubber sealant, strutting piece and retainer plate constitute, rubber sealant 2 and strutting piece 2-1 are provided with cable hole 3 and are used to pass cable hole, and retainer plate cooperates with the overcoat pipe thread mouth and is used for fixing rubber sealant and strutting piece; Have several cable hole on rubber sealant, the strutting piece, cable hole is communicated to the outer rim of rubber sealant at least by an otch.Can cable be worn to cable hole by connection place of rubber sealant otch and need not cut off cable (perhaps install and to pass through complicated cover snare) to assigned address.
The end of outer tube 1 is a truncated cone-shaped tube, caulking gum layer 4 also is a truncated cone-shaped, what be complementary inserts in the truncated cone-shaped tube, retainer plate is that (two semicircular retainer plates are combined into a whole circle for the retainer plate of two semicircular band external spirals, also claim Hough screw fixed circle) 9, instrument binding groove 9-1, compress step 9-2, outer tube 1 end is provided with inside spin, is complementary with the retainer plate external spiral.Seal member can be integrated with outer tube, also can establish a sleeve pipe in addition and be used to install rubber sealant 2 and strutting piece 2-1; This sleeve pipe can friction tightly be enclosed within the outer tube or pipe outside.
Being provided with projection on the excircle of outer tube uses as anti-skidding block.
Be provided with the adjusting rubbery loop that the aperture lasso constitutes between rubber sealant 2 and the strutting piece, described adjusting rubbery loop is the aperture lasso, the external diameter of lasso is greater than the cable hole on the caulking gum layer 43, be used to wrap up and cable that potted line footpath is thinner, still can guarantee when thin cable passes sealing cable hole.
Retainer plate by compress step 9-2 fixedly rubber sealant, strutting piece can make slightly dilatancy of rubber sealant, make cable hole form sealing; Cable footpath also can seal by the adjusting rubbery loop that the aperture lasso constitutes during less than cable hole.The central authorities of rubber sealant are passed by round platform post screw rod 11, make rubber sealant produce bigger dilatancy sealing.
The invention has the beneficial effects as follows: cable and optical cable etc. enter the guiding and the protective device of building from trench, structure is concisely reliable, and is easy for installation, and sealing effectiveness is much better than prior art products; Avoided underground water to enter in the underground structure, can satisfy watertight (also the reaching the insect protected protection against rodents) performance requirement in the various engineering structures along cable.
