Description

Technical Field

[0001] The present application relates to the technical field of air-blown micro-cable construction, and in particular to a micro-cable sealing connector. Background Art

[0002] In recent years, with the development of communication technology, the optical fiber laying process of air-blown optical cable has also been studied and practiced more. This process can avoid repeated excavation of the road surface to bury the optical cable pipeline, has high laying efficiency, and can ensure the protection of optical fiber during construction and use. Therefore, the process of laying optical cables by high-pressure air blowing is becoming more and more widely used.

[0003] However, the following problems exist in the process of laying optical cables in pipelines: when there are branches in the pipeline, the high-pressure airflow will be diverted to the branches, causing waste, increasing the laying cost and difficulty; when multiple wire harnesses are passed through the branch pipeline, the existing seals cannot effectively fill and seal the gaps between the wire harnesses. Utility Model Content

[0004] The technical problem to be solved by the utility model is that when laying optical cables in pipelines by high-pressure air blowing, there are branches in the pipelines, which are difficult to close. To this end, the application provides a device that can seal the branch through which the optical cable is passed by deformation of the inner diameter, so that the high-pressure airflow can pass through the pipeline to be laid without loss, thereby improving the laying efficiency.

[0005] In order to solve the above technical problems, the utility model provides a micro-cable sealed connector, including a connecting tube body, an integrally formed limiting boss and a clamping seat are provided inside the tube body at one end of the connecting tube body, an external thread is provided on the outer surface of the other end of the connecting tube body, a nut sleeve is threaded on the external thread end, and a quick connection seat is clamped in the nut sleeve, and a quick connector is provided at each end of the connecting tube body, which is respectively connected to the quick connection seat and the clamping seat, and a locking ring, a limiting ring and a sealing gasket are provided in sequence between the limiting boss and the quick connection seat inside the connecting tube body, a sealing gasket is provided between the limiting boss and the quick connector, and a conical convex is provided on the inner wall of the locking ring, and the conical convex is arranged in a ring shape on the inner wall of the locking ring.

[0006] Furthermore, the quick connector includes a pipe head, which is clamped in the clamping tube. The quick connector also includes a reed seat, the inner side of the reed seat is a cone surface, and a reed is provided between the pipe head and the cone surface in the clamping tube.

[0007] Furthermore, a C-shaped gasket is provided between the clamping tube and the tube head.

[0008] Furthermore, the outer surface of the clamping tube has a sloped hook body which is locked and limited with the quick-connect seat or the clamping seat.

[0009] Furthermore, the inner diameters of the limiting boss and the limiting ring are smaller on the side close to the locking ring and larger on the other side.

[0010] Furthermore, the outer surface of the quick connector is provided with a hook body which is locked and limited with the connecting tube body.

[0011] In summary, the beneficial effects of the utility model are that the locking ring can be tightly wrapped around the optical cable bundle after being squeezed and deformed, and the conical convexity arranged on the inner wall of the locking ring can fill the gaps between multiple bundles, thereby achieving the effect of sealing the branch, and the conical convex side surface will not block the bundle during the air blowing transportation of the micro-tube micro-cable.

[0021] The following will be combined with the drawings of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described content cannot fully exemplify all implementation schemes. The following examples are only a part of many implementation schemes, not all examples. Based on the disclosure of the utility model, all other implementation results obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1 and Figure 4 As shown, a micro cable sealing connector includes a connecting tube body 1, one end of the connecting tube body 1 is provided with an integrally formed limiting boss 11 and a clamping seat 12 inside the tube body, and the other end of the connecting tube body 1 is provided with an external thread 13 on the outer surface, and a nut sleeve 2 is screwed on the end of the external thread 13. Figure 2 As shown, the nut sleeve 2 is clamped with the quick-connection seat 3, and the two ends of the connecting pipe body 1 each have a quick connector 4 connected to the quick-connection seat 3 and the clamping seat 12 respectively. Figure 2 and Figure 4 As shown, tightening the nut sleeve 2 can push the quick connector seat 3 and the quick connector 4 further into the connecting tube body 1, thereby achieving a better effect of fastening the optical fiber harness.

[0024] like Figure 4 As shown, inside the connecting tube body 1, a locking ring 5, a limiting ring 6 and a sealing gasket 7 are sequentially arranged between the limiting boss 11 and the quick connector 3, and a sealing gasket 7 is arranged between the limiting boss 11 and the quick connector 4. When the nut sleeve 2 is tightened, the quick connector 3 pushes the sealing gasket 7 and the limiting ring 6 to squeeze the locking ring 5, which can be deformed to a certain extent, toward the limiting boss 11, so that the inner diameter of the locking ring 5 after being squeezed is reduced, thereby filling the gap between the locking ring 5 and the optical fiber bundle, thereby achieving a sealing effect.

[0025] like Figure 7 and Figure 8 As shown, the inner wall of the locking ring 5 is provided with a cone convex 51, and the cone convex 51 is arranged in a ring shape on the inner wall of the locking ring 5. The cone convex 51 provided on the inner wall of the locking ring 5 can fill the gaps between multiple wire bundles, and the side of the cone convex 51 will not block the wire bundles during the air blowing transportation of the micro-duct micro-cable.

[0026] like Figure 3 As shown, the quick connector 4 includes a pipe head 41, which is clamped in a clamping tube 42, and the quick connector 4 also includes a reed seat 43. Figure 5 As shown, the inner side of the spring seat 43 is a conical surface 431, and a spring 44 is provided between the tube head 41 and the conical surface 431 in the clamping tube 42. When the tube head 41 is assembled into the clamping tube 42, the spring 44 can conform to the conical surface 431 of the spring seat 43 to produce a certain deformation and act on the outer wall of the micro-tube micro-cable sheath to prevent the micro-tube micro-cable from sliding back out of the quick connector 4 after being inserted.

[0027] like Figure 3 and Figure 6 As shown, a C-shaped gasket 45 is provided between the clamping tube 42 and the tube head 41. When the quick connector is removed, the tube head 41 can be easily and conveniently removed by applying force to the notch of the C-shaped gasket 45.

[0028] like Figure 2 As shown, the outer surface of the clamping tube 42 has a slope hook 421 that is locked and limited with the quick-connect seat 3 or the clamping seat 12.

[0029] like Figure 4 As shown, the inner diameter of the limiting boss 11 and the inner diameter of the limiting ring 6 are smaller on the side close to the locking ring 5 and larger on the other side. The side with the larger inner diameter is for the convenience of inserting the micro-tube and micro-cable, and the side with the smaller inner diameter is close to the locking ring 5, which is convenient for uniformly squeezing the locking ring 5 to make it longitudinally compressed and deformed, and the degree of reduction of the inner diameter of the locking ring 5 can be adjusted by the degree of tightening the nut 2, so as to achieve the effect of sealing micro-tubes and micro-cables of different diameters. At the same time, due to the smaller inner diameter, the locking ring 5 will not deform from the outer diameter to the inner diameter and get stuck in the inner diameter of the limiting boss 11 or the limiting ring 6, so that the deformation is limited and cannot be adjusted, and it is difficult to restore and disassemble.

[0030] like Figure 2 As shown, the outer surface of the quick connector 3 has a hook 31 that is locked with the connecting tube 1. An opening corresponding to the hook 31 is provided at the external thread 13 of the connecting tube 1, and the hook 31 falls into the opening to limit the range of movement of the quick connector 3, making the disassembly and assembly of the micro cable sealing connector faster and more efficient.

[0031] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned implementation modes. Equivalent changes made to the structure, shape and principle within the knowledge scope of ordinary technicians in the relevant technical field all fall within the protection scope of the utility model.
