Abstract
The invention relates to a stretching resistance cable connector, comprising a shell and a sleeve, wherein the connecting end of the sleeve is connected with the shell by a connecting ring; the shell and the sleeve are provided with a through cable channel; the cable channel of the sleeve is provided with a cone hole section and a threaded section; the major diameter end of the cone hole section is arranged close to the connecting end of the sleeve; the threaded section is arranged close to the major diameter end of the cone hole section; a taper sleeve I is arranged inside the cone hole section; a taper sleeve II is arranged in a cone hole of the taper sleeve I; the threaded section is internally provided with a jacking swivel nut in a screwing way; the jacking swivel nut is arranged in a way of jacking the taper sleeve II after being screwed. The stretching resistance cable connector is simple and compact in structure, the taper sleeves are enabled to move to the tension direction under the simultaneous effect of the friction and the tension when a cable is stressed, and the stretching resistance function is realized.
Description
Technical field
The present invention relates to connector technique field, be specifically related to a kind of stretching resistance cable connector.
Background technology
At present, many marine system users have proposed the demand of stretching resistance product, have stretching resistance function after requiring product to be connected with cable.For stretching resistance structure, at middle cable, can adopt pulling force rope knotting or through the mode of tensile elements crimping, realize the stretching resistance demand of product, but stretching resistance structure is the restriction due to its distributed architecture at the cable of circle distribution, be difficult to adopt the modes such as knotting, just need to guarantee by other structures.I mainly adopt tapered sleeve structure at company's existing product structure, by clamp nut compress gasket, give stretching resistance layer pretightning force, under cable stressing conditions, tapered sleeve is strained gradually, realize stretching resistance function, as shown in Figure 1, the pretightning force between tapered sleeve and sleeve depends on the active force of clamp nut to concrete structure, if the pretightning force of clamp nut time is less, the suffered thrust of stretching resistance layer is also little; Stressed the tightening of stretching resistance layer when cable bearing tension, between sleeve and tapered sleeve, there is gap (or thrust reduces), if now the frictional force between stretching resistance layer and tapered sleeve can not drive tapered sleeve to being subject to force direction when motion, the situation that just there will be stretching resistance to lose efficacy.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of stretching resistance cable connector is provided, compact conformation is simple, by frictional force and pulling force, acts on simultaneously, guarantees that tapered sleeve moves to direction of pull under cable stressing conditions, realizes stretching resistance function.
The present invention is the deficiency solving the problems of the technologies described above, the technical scheme adopting is: a kind of stretching resistance cable connector, comprise housing and sleeve, the link of sleeve is connected with housing by connecting ring, housing and sleeve have the cable passage of perforation, the cable passage of described sleeve has a taper hole section and a thread segment, the bigger diameter end of taper hole section is near the link setting of sleeve, thread segment is near the bigger diameter end setting of taper hole section, in described taper hole section, be provided with tapered sleeve I, in the taper hole of tapered sleeve I, be provided with tapered sleeve II, in thread segment, screw to be provided with and hold out against swivel nut, hold out against and after swivel nut screws, hold out against the setting of tapered sleeve II.
The described corresponding tapered sleeve II of the swivel nut one end that holds out against is provided with annular protrusion.
The cone angle scope of the taper hole of described taper hole section and tapered sleeve I is 5～10 °.
The axial length of described tapered sleeve II is half of tapered sleeve I axial length.
beneficial effect
Stretching resistance cable connector of the present invention is simple and compact for structure, by frictional force and pulling force, acts on simultaneously, guarantees that tapered sleeve moves to direction of pull under cable stressing conditions, realizes stretching resistance function.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the connector tapered sleeve stretching resistance structure of prior art;

Fig. 3 is the structural representation of sleeve of the present invention;
Mark in figure: 1, housing, 2, sleeve, 3, link, 4, connecting ring, 5, taper hole section, 6, thread segment, 7, tapered sleeve I, 8, tapered sleeve II, 9, hold out against swivel nut, 10, stretching resistance layer.
Embodiment
As shown in Figure 1, be tapered sleeve stretching resistance structure of the prior art: the pretightning force between tapered sleeve and sleeve depends on the active force of clamp nut, if the pretightning force of clamp nut time is less, the suffered thrust of stretching resistance layer is also little; , there is gap between sleeve and tapered sleeve in stressed the tightening of stretching resistance layer when cable bearing tension, if now the frictional force between stretching resistance layer and tapered sleeve can not drive tapered sleeve when being subject to force direction motion, and the situation that just there will be stretching resistance to lose efficacy.
As shown in Figure 2,3, stretching resistance cable connector of the present invention, comprise housing 1 and sleeve 2, sleeve 2 has a link 3, the link 3 of sleeve 2 is connected with housing 1 by connecting ring 4, connecting ring 4 comprises two half-connection rings, after two half-connection latch closures close, housing 1 is connected with sleeve 2, and housing 1 can not relatively rotate after being connected with sleeve 2 between the two.Housing 1 and sleeve 2 have the cable passage of perforation, and cable passage can hold the cable that needs connect.The cable passage of described sleeve 2 has a taper hole section 5 and a thread segment 6, the bigger diameter end of taper hole section 5 arranges near the link 3 of sleeve 2, thread segment 6 is near the bigger diameter end setting of taper hole section 5, in described taper hole section 5, be provided with tapered sleeve I 7, the cone angle scope of the taper hole of taper hole section 5 and tapered sleeve I 7 is 5～10 °, the taper hole inwall of the outer wall of tapered sleeve I 7 and taper hole section 5 is bonded to each other, whole tapered sleeve I 7 just can be installed in the taper hole of taper hole section 5, now between the inwall of sleeve 2 and tapered sleeve I 7 outer walls, forms the space that can push.In the taper hole of described tapered sleeve I 7, be provided with tapered sleeve II 8, the axial length of tapered sleeve II 8 is half of tapered sleeve I 7 axial lengths.Whole tapered sleeve II 8 just can be installed in the taper hole of tapered sleeve I 7, screws to be provided with to hold out against swivel nut 9 in thread segment 6, holds out against the corresponding tapered sleeve II of swivel nut 98 one end and is provided with annular protrusion, and after holding out against swivel nut 9 and screwing, its annular protrusion holds out against tapered sleeve II 8 and arranges.
Stretching resistance connector of the present invention in use, first the outside stretching resistance layer 10 of cable is peeled off, then cable is penetrated in sleeve 2, and the stretching resistance layer 10 of peeling off is folded between the outer wall of tapered sleeve I 7 and the taper hole inwall of taper hole section 5, then after stretching resistance layer 10 being turned back, be folded in the gap forming between tapered sleeve I 7 and tapered sleeve II 8, finally screw and hold out against swivel nut 9 and make the annular protrusion that holds out against swivel nut 9 hold out against tapered sleeve II 8, guarantee that tapered sleeve moves to direction of pull under cable stressing conditions, realize stretching resistance function.
