Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, and more specifically to a cable connector with a sealed structure and stable connection. Background Technology

[0002] Currently, cables are widely used in the electrical engineering 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 coaxially disposed inside the receiving end or the cap. The cap is screwed onto the receiving end. The sealing ring is fitted outside the outer end. The nut is screwed onto 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.

[0003] The aforementioned existing technology has several drawbacks. First, if the sealing sleeve is housed within the receiving end, the size and specifications of the sealing sleeve are required to be high and replacement is difficult. If the sealing sleeve is housed within the cap, during the process of disassembling the cap, there is a risk of poor tightness between the sealing sleeve and the cap, which can cause the sealing sleeve to fall off and be lost, affecting maintenance efficiency. Second, when the outer end is not screwed with a nut, the sealing ring can easily move relative to the outer end due to differences in tightness or a large inner diameter, or even fall off the outer end, affecting assembly efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cable connector in which both the sealing sleeve and the sealing ring are reliably connected.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable connector with a stable sealed structure, 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. The sealing sleeve is positioned at the port of the receiving end and is received within the cap. A flexible connector connected to the sealing ring is provided at the edge of the end face of the sealing sleeve facing the convex ring. A groove is provided on the peripheral wall of the receiving end for partial reception of the connector.

[0006] As a further improvement of this utility model, the connector is straight, and the outer wall of the convex ring is provided with a connecting groove that connects with the broken groove and allows the connector to be partially accommodated. The connection between the connector and the sealing ring is close to the inner edge of the sealing ring.

[0007] As a further improvement of this utility model, the connector is bent and fits in sequence with the outer wall of the convex ring, the end face of the convex ring and the bottom of the groove, and the connection between the connector and the sealing ring is located at the outer edge of the sealing ring.

[0008] As a further improvement of this utility model, the connecting member includes a tightening ring sleeved outside the receiving end and fitted to the end face of the convex ring, a plurality of secondary connecting strips connecting the tightening ring and the sealing ring and fitted to the outer wall of the convex ring, and a main connecting strip connecting the sealing sleeve and the tightening ring and fitted to the bottom of the broken groove.

[0009] The beneficial effects of this utility model are as follows: By connecting the sealing sleeve and the sealing ring with the connector, both the sealing sleeve and the sealing ring remain stationary relative to the wiring body after the wiring body is assembled. This design effectively improves the connection stability between the sealing sleeve and the sealing ring compared to the prior art. At the same time, connecting the sealing sleeve and the sealing ring can effectively prevent the sealing sleeve from being lost, and also makes the replacement of the sealing sleeve more convenient, which helps to improve maintenance efficiency.

[0017] 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.

[0018] Reference Figures 1 to 6As shown, a cable connector with a stable sealed structure 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.

[0019] Based on the aforementioned prior art, the outer diameter of the sealing sleeve 2 is less than or equal to the outer diameter of the receiving end 13, and the inner diameter of the sealing sleeve 2 is greater than or equal to the inner diameter of the receiving end 13. A portion is cut off on the peripheral wall of the receiving end 13 to form a groove 14 that cuts off the external thread of the receiving end 13. The depth of the groove 14 should meet the requirement that the connecting piece 6 and the cap 3 do not interfere with each other when the cap 3 is screwed to the receiving end 13. The sealing sleeve 2 and the sealing ring 4 are connected by the connecting piece 6. The connecting piece 6 has the characteristic of elastic deformation. The following three embodiments will be used to describe different shapes of the connecting piece 6. At the same time, the manufacturer can choose different shapes of the connecting piece 6 for production according to the actual production needs. Example

[0020] In this technical solution, such as Figure 1 and Figure 2 As shown, a connecting groove 15 is machined on the outer wall of the convex ring 11, with the bottom of the groove flush with the bottom of the broken groove 14. The connecting groove 15 and the broken groove 14 are on the same vertical line. The connecting piece 6 is a flat and straight strip. The part of the sealing sleeve 2 that protrudes relative to the bottom of the broken groove 14 is connected to one end of the connecting piece 6. If the outer diameter of the receiving end 13 is the same as that of the outer end 12, the other end of the connecting piece 6 is connected to the sealing ring 4 at the inner edge of the sealing ring 4.

[0021] During assembly, the sealing ring 4 is placed on the outer end 12 and moved to a position that fits against the end face of the convex ring 11. The connecting piece 6 bends outward towards the convex ring 11 due to the weight of the sealing sleeve 2. Then, the sealing ring 4 can be rotated coaxially relative to the outer end 12 to move the connecting piece 6 to correspond with the connecting groove 15. Then, the sealing sleeve 2 is moved to the port of the receiving end 13. The sealing sleeve 2 and the receiving end 13 are coaxially arranged. The connecting piece 6 changes from a bent shape to a straight shape as the sealing sleeve 2 changes. The upper and lower parts of the connecting piece 6 are located in the broken groove 14 and the connecting groove 15 respectively. The bottom of the broken groove 14 and the connecting groove 15 are both in contact with the connecting piece 6. Finally, the cap 3 is placed on the outer end 12 and screwed into the receiving end 13. The nut 5 is screwed into the outer end 12.

[0022] During use, after the nut 5 is removed, the sealing sleeve 2 remains confined within the cap 3, and the connector 6 and sealing ring 4 remain stationary. During maintenance, when the cap 3 is removed, the sealing sleeve 2 is restricted by the connector 6 and sealing ring 4 and will not move with the cap 3 or separate from it. If the sealing sleeve 2 or sealing ring 4 is damaged, the cap 3 and nut 5 are removed in sequence, the sealing sleeve 2 is flipped outward toward the receiving end 13, the connector 6 changes from a straight shape to a bent shape, and then the sealing ring 4 is removed from the outer end 12.

[0023] This design effectively improves the connection stability between the sealing sleeve 2 and the sealing ring 4 compared to existing technologies. At the same time, the connection between the sealing sleeve 2 and the sealing ring 4 can effectively prevent the sealing sleeve 2 from being lost, and also make the replacement of the sealing sleeve 2 more convenient, which helps to improve maintenance efficiency. Example

[0024] In this technical solution, such as Figure 3 and Figure 4 As shown, the connector 6 is bent and divided into three sections with two bends. The two ends of the connector 6 are connected to the end face edge of the sealing sleeve 2 and the end face edge of the sealing ring 4, respectively. A slot can be selectively opened on the outer wall of the convex ring 11 to accommodate the connector 6. There is a drop between the bottom of the slot and the bottom of the groove 14. The purpose of the slot is to accommodate the connector 6 in the slot and keep it flush with the outer wall of the convex ring 11.

[0025] During assembly, the sealing ring 4 is placed on the outer end 12 and moved to a position that fits against the end face of the convex ring 11. The connecting piece 6 bends outward towards the convex ring 11 due to the weight of the sealing sleeve 2. Then, the sealing ring 4 can be rotated coaxially relative to the outer end 12 to move the connecting piece 6 to correspond with the groove 14. Then, the sealing sleeve 2 is moved to the port of the receiving end 13. The sealing sleeve 2 and the receiving end 13 are coaxially arranged. The connecting piece 6 swings with the sealing sleeve 2 until the three sections of the connecting piece 6 fit against the outer wall of the convex ring 11, the end face of the convex ring 11, and the bottom of the groove 14, respectively. Finally, the cap 3 is placed on the outer end 12 and screwed into the receiving end 13. The nut 5 is screwed into the outer end 12.

[0026] During use, after the nut 5 is removed, the sealing sleeve 2 remains confined within the cap 3, and the connector 6 and sealing ring 4 remain stationary. During maintenance, when the cap 3 is removed, the sealing sleeve 2 is restricted by the connector 6 and sealing ring 4 and will not move with the cap 3 or separate from it. If the sealing sleeve 2 or sealing ring 4 is damaged, the cap 3 and nut 5 are removed in sequence, the sealing sleeve 2 is flipped outward toward the receiving end 13, the connector 6 changes from a straight shape to a bent shape, and then the sealing ring 4 is removed from the outer end 12.

[0027] This design effectively improves the connection stability between the sealing sleeve 2 and the sealing ring 4 compared to existing technologies. At the same time, the connection between the sealing sleeve 2 and the sealing ring 4 can effectively prevent the sealing sleeve 2 from being lost. Furthermore, the replacement of the sealing sleeve 2 is more convenient, which helps to improve maintenance efficiency. Moreover, compared to Embodiment 1, it is possible to choose not to open the groove on the outer wall of the convex ring 11 or not to open a deep groove, which effectively simplifies the processing technology of the wiring body 1, indirectly ensures the structural stability of the wiring body 1, and can also prevent the accumulation of external impurities in the groove, which can accelerate the local aging of the connector 6 and make it easy to break. Example

[0028] In this technical solution, such as Figure 5 and Figure 6 As shown, the sealing ring 4 has multiple secondary connecting strips 62 integrally formed on its end face. The multiple secondary connecting strips 62 are geometrically distributed around the axis of the sealing ring 4. The other end of the multiple secondary connecting strips 62 is connected to the same tightening ring 61. The tightening ring 61 and the sealing ring 4 are coaxially arranged and have the same outer contour. The multiple secondary connecting strips 62 are located at the edge of the sealing ring 4. The length of the multiple secondary connecting strips 62 is the same as the length of the convex ring 11. A main connecting strip 63 is connected to the end face of the tightening ring 61 away from the convex ring 11. The other end of the main connecting strip 63 is connected to the sealing sleeve 2.

[0029] During assembly, the main connecting strip 63 is curved and the sealing sleeve 2 is located outside the tightening ring 61. The tightening ring 61 is first fitted onto the outer end 12. As the tightening ring 61 moves along the length of the outer end 12, the sealing ring 4 is then fitted onto the outer end 12. When the tightening ring 61 moves to the convex ring 11, the tightening ring 61 is stretched outward so that the inner diameter of the tightening ring 61 is larger than the outer diameter of the convex ring 11, and multiple secondary connecting strips 62 are stretched. Then, the tightening ring 61 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 61 moves... Outside the receiving end 13, loosen the tightening ring 61. The tightening ring 61 restores its elastic deformation and contracts towards the receiving end 13. Once the tightening ring 61 has contracted to its position, the multiple secondary connecting strips 62 restore their deformation and fit against the outer wall of the convex ring 11. The tightening ring 61 fits against the other end face of the convex ring 11. The sealing ring 4 is fixed relative to the outer end 12. Then, screw the nut 5 onto the outer end 12 and make the nut 5 touch the sealing ring 4. Next, move the sealing sleeve 2 to the port of the receiving end 13. The main connecting strip 63 changes from a curved shape to a straight shape as the sealing sleeve 2 changes and fits against the bottom of the groove 14. Finally, install the cap 3.

[0030] During use, after the nut 5 is removed, the sealing sleeve 2 remains confined within the cap 3, and both the connector 6 and the sealing ring 4 remain stationary. During maintenance, when the cap 3 is removed, the sealing sleeve 2 is restricted by the connector 6 and the sealing ring 4 and will not move with the cap 3 or separate from it. If it is necessary to replace the sealing ring 4 or the sealing sleeve 2, remove the cap 3 and the nut 2, swing the sealing sleeve 2 to the side of the tightening ring 61, and then expand the tightening ring 61 outwards towards the convex ring 11. This process is repeated multiple times. The connecting strips 62 all become longer and partially separate from the outer wall of the convex ring 11 until the inner diameter of the tightening ring 61 is larger than the outer diameter of the convex ring 11. Then, a force is applied along the axial direction of the convex ring 11 to make the tightening ring 61, multiple secondary connecting strips 62 and sealing ring 4 move together along the axial direction of the convex ring 11 until the tightening ring 61 is completely separated from the convex ring 11. The force applied to the tightening ring 61 is released, and the tightening ring 61 is pulled back towards the axis of the outer end 12. Finally, the sealing ring 4, connecting piece 6 and sealing sleeve 2 are moved out of the outer end 12 as a whole.

[0031] This design effectively improves the connection stability between the sealing sleeve 2 and the sealing ring 4 compared to existing technologies. Furthermore, the connection between the sealing sleeve 2 and the sealing ring 4 effectively prevents the sealing sleeve 2 from being lost, and the replacement of the sealing sleeve 2 is more convenient, improving maintenance efficiency. Moreover, compared to embodiments one and two, the structure of the connecting piece 6 is more three-dimensional and has greater structural strength, making it less prone to damage and indirectly extending its service life. The design of the tightening ring 61 tightening onto the convex ring 11 ensures the connection stability of the sealing ring 4, facilitating the smooth and stable placement of the sealing sleeve 2 on the receiving end 13. This avoids situations where the sealing sleeve 2 is difficult to place on the receiving end 13 due to loosening of the sealing ring 4, or where the sealing ring 4 causes the sealing sleeve 2 to detach from the receiving end 13. It also compensates for the instability in the connection of the sealing ring 4 caused by the breakage of the main connecting strip 63.

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.
