Description

Technical Field

[0001] This utility model relates to the field of cable technology, and more specifically to a waterproof cable connector with a reliable sealing ring connection. Background Technology

[0002] Currently, cables are widely used in the electrical industry. The main function of cable connectors is to ensure smooth circuit flow, maintain cable sealing, and guarantee the insulation level at the cable joint, enabling safe and reliable operation. Existing cable connectors include a connector body, a sealing sleeve, a cap, a sealing ring, and a nut. The connector body includes a convex ring, an outer end located on both sides of the convex ring, and a receiving end. The sealing sleeve is located inside the receiving end or the cap. The cap is screwed onto the outside of the receiving end. The sealing ring is fitted onto the outside of the outer end. The nut is screwed onto the outside of the outer end and confines the sealing ring between the nut and the convex ring. When putting the cable connector into use, the nut needs to be removed, and the cable is passed through the connector body, sealing sleeve, and cap in sequence. The outer end is fixedly connected to the corresponding cable equipment. The sealing ring and sealing sleeve work together to provide waterproofing. However, existing technology has defects. When the outer end is not screwed with a nut, the sealing ring is prone to moving relative to the outer end due to differences in tightness or a large inner diameter, or even falling off the outer end, affecting assembly efficiency. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waterproof cable connector that provides a stable connection between the sealing ring and the external end and is easy to assemble.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof cable connector with reliable sealing ring connection, comprising a wiring body, a sealing sleeve, a cap, a sealing ring, and a nut. The wiring body includes a convex ring, an outer end located on both sides of the convex ring, and a receiving end. The sealing ring is sleeved on the outer end. It also includes a tightening ring sleeved on the receiving end and fitting against the convex ring, and multiple connecting strips connecting the tightening ring and the sealing ring. The multiple connecting strips are distributed around the axis of the sealing ring and fitting against the outer wall of the convex ring.

[0005] As a further improvement of this utility model, a groove for accommodating the connecting strip is provided on the outer wall of the convex ring.

[0006] As a further improvement of this utility model, the inner diameter of the tightening ring is larger than the inner diameter of the sealing ring.

[0007] As a further improvement of this utility model, the number of connecting strips is three or four.

[0008] The beneficial effects of this utility model are as follows: By tightening the tightening ring and connecting strips onto the end face and outer wall of the convex ring respectively, the sealing ring always remains in contact with the other side of the convex ring. Compared with the prior art, this design can ensure that the sealing ring remains in contact with the end face of the convex ring even without a nut, and the sealing ring connection is stable, indirectly improving the assembly efficiency of the external end with the nut or other external parts. Compared with the design of using a sleeve to connect the tightening ring and the sealing ring, the design of multiple connecting strips connecting the tightening ring and the sealing ring can reduce the elastic resistance encountered when the tightening ring expands outward, facilitate the rapid deformation of the tightening ring, thereby improving the efficiency of the tightening ring assembly and disassembly, and also reducing material costs.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0013] Reference Figure 1 and Figure 2 As shown, a waterproof cable connector with reliable sealing ring connection in this embodiment includes a wiring body 1, a sealing sleeve 2, a cap 3, a sealing ring 4, and a nut 5. The wiring body 1 includes a convex ring 11, an external end 12 located on both sides of the convex ring 11, and a receiving end 13. The sealing ring 4 is sleeved on the external end 12.

[0014] Based on the aforementioned prior art, the sealing ring 4 has multiple connecting strips 7 integrally formed on its end face. The multiple connecting strips 7 are geometrically distributed around the axis of the sealing ring 4. The other end of the multiple connecting strips 7 is connected to the same tightening ring 6. The tightening ring 6 is coaxially arranged with the sealing ring 4 and the two have the same outer contour. The multiple connecting strips 7 are all located at the edge of the sealing ring 4. The length of the multiple connecting strips 7 is the same as the length of the convex ring 11. The sealing ring 4, the connecting strips 7 and the tightening ring 6 are all made of elastic material.

[0015] During the installation of the sealing ring 4, the tightening ring 6 is first fitted onto the outer end 12. As the tightening ring 6 moves along the length of the outer end 12, the sealing ring 4 is subsequently fitted onto the outer end 12. When the tightening ring 6 moves to the convex ring 11, it is stretched outward so that the inner diameter of the tightening ring 6 is larger than the outer diameter of the convex ring 11, and all the connecting strips 7 are stretched. Then, the tightening ring 6 continues to move along the length of the convex ring 11 until the sealing ring 4 is in contact with the end face of the convex ring 11. The tightening ring 6 moves to the receiving end 13, and is then released. The tightening ring 6 recovers its elastic deformation and contracts towards the receiving end 13. Once the tightening ring 6 has contracted to its final position, all the connecting strips 7 recover their deformation and are in contact with the outer wall of the convex ring 11. 6 is fitted to the other end face of the convex ring 11, and the sealing ring 4 is fixed relative to the outer end 12. Then, the nut 5 is screwed on the outside of the outer end 12 and the nut 5 touches the sealing ring 4. If it is necessary to remove the sealing ring 4, the tightening ring 6 is expanded outward of the convex ring 11, and the multiple connecting strips 7 are lengthened and partially separated from the outer wall of the convex ring 11 until the inner diameter of the tightening ring 6 is greater than the outer diameter of the convex ring 11. Then, a force along the axial direction of the convex ring 11 is applied to make the tightening ring 6, the multiple connecting strips 7 and the sealing ring 4 move together along the axial direction of the convex ring 11 until the tightening ring 6 is completely separated from the convex ring 11. The force applied to the tightening ring 6 is released, and the tightening ring 6 is folded towards the axis of the outer end 12. Finally, the sealing ring 4, the multiple connecting strips 7 and the tightening ring 6 are moved out of the outer end 12.

[0016] Compared with existing technologies, this design ensures that the sealing ring 4 remains in contact with the end face of the convex ring 11 even without the nut 5, and the sealing ring 4 is stably connected, indirectly improving the assembly efficiency of the external end 12 with the nut 5 or other external parts. Compared with the design of using a sleeve to connect the tightening ring 6 and the sealing ring 4, the design of multiple connecting strips 7 can reduce the elastic resistance encountered by the tightening ring 6 when it expands outward, facilitate the rapid deformation of the tightening ring 6, thereby improving the assembly and disassembly efficiency of the tightening ring 6, and also reducing material costs.

[0017] As one specific implementation method of the improvement, refer to Figure 2 As shown, multiple grooves 14 are machined on the outer wall of the convex ring 11 to accommodate multiple connecting strips 7. The outer contours of the sealing ring 4 and the tightening ring 6 are the same as the outer contours of the end face of the convex ring 11. Compared with the design where the connecting strip 7 protrudes relative to the outer wall of the convex ring 11, this design can prevent the connecting strip 7 from being broken by bumps or friction, indirectly improving the structural stability of the connecting strip 7. At the same time, the sealing ring 4 and the tightening ring 6 have a more compact structure and are flush with the outer wall of the convex ring 11, which reduces the wear of the outer edges of the sealing ring 4 and the tightening ring 6.

[0018] As one specific implementation method of the improvement, refer to Figure 2As shown, the inner diameter of the tightening ring 6 is larger than that of the sealing ring 4. This design facilitates the expansion of the tightening ring 6, making it easier for the tightening ring 6 to deform under stress and improving the efficiency of disassembly and assembly.

[0019] As a further improvement to this utility model, refer to Figure 2 As shown, the number of connecting strips 7 is three or four and they are geometrically distributed. This design can compensate for the defect that the large number of connecting strips 7 causes the tightening ring 6 to be subjected to greater elastic resistance when it expands outward. The tightening ring 6 is restricted at fewer points, making it easier to expand outward and deform, thereby further improving the assembly and disassembly efficiency of the tightening ring 6.

[0020] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
