Described joint body (1) is shaped as cylindrical tube.
The length of described cone rubber pad (6) is all not less than the length of annular seal space (2).
The present invention is through being applied to submerged cable butt-joint operation engineering, prove to have simple in structure, locking cable pulling force strong, sealing reliable, uses, advantage easy to maintenance, the long term seal that is suitable for submerged cable connects.
Accompanying drawing explanation
Fig. 1 is the front view of the watertight connector of submerged cable docking of the present invention.
Fig. 2 is the A-A face cutaway view of the watertight connector of Fig. 1 institute sand submerged cable docking.
In figure: 1-joint body, 2-annular seal space, 3-fluid sealant, 4-interior catch, 5-outer catch, 6-cone rubber pad, 7-locking screw, 8-clamping nut, 9-cable, 10-cable joint.
embodiment
The technology of the present invention principle is: joint body 1 its aperture is slightly larger than cable 9 diameters of axle, and two sections of cables 9 complete after docking, the centre position by cable joint 10 along axial immigration annular seal space 2.Live after exposed cable joint 10 when interior injection fluid sealant 3 embeddings of annular seal space 2, cable joint 10 has just had good watertightness performance, and fluid sealant 3 is direct sealants of first that watertight connector provides for exposed cable joint 10; The two ends of joint body 1 are locking and two sealants of cable 9, and the two ends inner chamber of joint body 1 is the bellmouth outwards amplifying, with the bellmouth slightly larger in diameter of annular seal space 2 contact positions in the diameter of annular seal space 2, for the location of interior catch 4.Two end surfaces of joint body 1 are processed to screw thread, for screwing in clamping nut 8.The cone rubber pad 6 being before enclosed within on cable 9 starts distortion under the extrusion effect of interior catch 4 and outer catch 5, the through-hole surfaces of passing for cable 9 on cone rubber pad 6 constantly radially inwardly expands, and makes coordinating from small matched in clearance between itself and cable 9 gradually become interference fit.Along with clamping nut 8 continues to screw, cable 9 is also more blocked tighter by cone rubber pad 6.This structure that can tighten up gradually cable 9 of watertight connector has guaranteed the resistance to tension between cable 9 and watertight connector, and the sealability of the second layer is provided for injecting the cable joint 10 of fluid sealant 3 again;
Joint body 1 profile of this watertight connector is cylinder, is mainly cylindrical tube, cylindrical tube by the machine-shaping of a cylinder steel entirety;
The length of cone rubber pad 6 is all not less than the length of annular seal space 2.Cone rubber pad 6 can need to be designed to certain length according to watertight index, after the through-hole surfaces of cone rubber pad 6 is all effectively closely knit with the outer surface of cable 9 in its length range, except cone rubber pad 6 and the interference fit of cable 9 can seal, the cone rubber pad 6 with certain length is in the tensile strength strengthening between self and cable 9, also lengthen the intrusion path of water, also can effectively stop outside water to be immersed in cylindrical tube inside, thereby avoid fluid sealant 3 in annular seal space 2 because losing efficacy in the state that is subject to water soaking for a long time, therefore cable joint (10) has been played again to indirectly sealing function of the second layer.
embodiment:the process that cable 9 is docked has following step: first all component by shown in Fig. 2, each parts are enclosed within respectively on the fore-end of two sections of cables 9 waiting, two cables 9 waiting are connected mutually, the cable joint 10 connecting is moved into the centre position of annular seal space 2; The interior catch 4, cone rubber pad 6, the outer catch 5 that are enclosed within cable joint 10 one end are pushed according to the order of sequence to the conical internal cavity of the termination of cylindrical tube, treat that interior catch 4, cone rubber pad 6, outer catch 5 all put in place, screw clamping nut 8; From the other end of the joint body 1 of cylindrical tube to the interior injection fluid sealant 3 of annular seal space 2, by 10 embeddings of exposed cable joint; After glue 3 to be sealed solidifies, by being enclosed within interior catch 4, cone rubber pad 6, outer catch 5 on homonymy cable 9 and also pushing to according to the order of sequence the conical internal cavity of cylindrical tube termination, treat that interior catch 4, cone rubber pad 6, outer catch 5 all put in place, screw clamping nut 8.
The following advantage of the present invention:
(a), simple and reasonable for structure, practical.
(b), tighten up cable by the dilatancy of cone rubber pad 6, have the advantages that tensile strength is large.
(c), cable joint 10 can provide two-layer underwater sealing, sealing is reliable, function admirable.Ground floor sealing is that fluid sealant 3 seals, and second layer sealing is that cone rubber pad 6 seals, and can meet the watertight requirement that is placed in for a long time cable under water;
(d), cheap, use, easy to maintenance.
(e), applicability is stronger: this joint can be used for the cable butting that bore is identical, also can be used for the different cable butting of bore.
The present invention can be made into a series of products, and the submerged cable docking that can meet different size is used.
