[0045] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented.

[0046] Example 1

[0047] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment discloses a connector device, which includes a base 1, a flange component 2 and a tolerance ring 3. The base 1 is inserted into the flange component 2 and can rotate in the flange component 2. The tolerance ring 3 is located in the flange component 2, and the tolerance ring 3 is pressed between the flange component 2 and the outer peripheral surface of the base 1. The tolerance ring 3 applies a force on the base 1 to limit the rotational movement of the base 1.

[0048] The base 1 is inserted into the flange part 2 and can rotate in the flange part 2, so that the base 1 and the flange part 2 can rotate relative to each other to adjust the orientation, so as to meet the requirements of installation and setting, and it is very convenient to use. The tolerance ring 3 is pressed between the flange part 2 and the base 1 and exerts a force on the base 1, thereby limiting the rotational movement of the base 1. After the installation is completed, the tolerance ring 3 is used to prevent the base 1 and the flange part 2 from rotating, so that the base 1 will not rotate loose during the use of the connector device, effectively avoiding abnormalities such as electrical connection failure or burning caused by loose connection, and greatly enhancing the reliability and service life of the electrical connection.

[0049] Of course, in special circumstances where the base 1 needs to be rotated for adjustment, a tool needs to be used to apply a force on the base 1 to overcome the force applied by the tolerance ring 3 on the base 1 to achieve rotational adjustment of the base 1.

[0050] In this embodiment, if Figure 3 As shown, the tolerance ring 3 is in the shape of a sheet, with a simple structure and convenient processing and manufacturing. The outer surface of the tolerance ring 3 may have a plurality of convex bumps 31 protruding outward; the outer surface of the tolerance ring 3 may also have a plurality of inwardly recessed grooves 32. The convex bumps 31 and the grooves 32 increase the thickness of the tolerance ring 3, so that less material is used for the tolerance ring 3. At the same time, the convex bumps 31 and the grooves 32 make the two sides of the tolerance ring 3 respectively abut against the outer peripheral surface of the base 1 and the inner wall surface of the flange component 2, thereby limiting the rotational movement of the base 1.

[0051] Specifically, a plurality of convex humps 31 and a plurality of grooves 32 are correspondingly arranged on both sides of the inner and outer sides of the tolerance ring 3, and the plurality of convex humps 31 are arranged at intervals along the circumference of the tolerance ring 3. The plurality of convex humps 31 and the plurality of grooves 32 can be processed and manufactured on the tolerance ring 3 by stamping, which is very convenient for processing and manufacturing. At the same time, the force applied to the outer peripheral surface of the base 1 and the inner wall surface of the flange component 2 is stable and reliable, and the stability is higher.

[0052] In this embodiment, the tolerance ring 3 has a break 33, through which the tolerance ring 3 can be expanded or reduced, so that the tolerance ring 3 can be used on bases 1 and flange components 2 with different outer diameters and inner diameters, with a wide range of applications and cost savings.

[0053] like Figure 2 and Figure 3 As shown, the flange component 2 includes a lower flange 21, an upper flange 22 and a union nut 23. The upper flange 22 is located above the lower flange 21. The upper and lower ends of the union nut 23 are respectively sleeved on the upper flange 22 and the lower flange 21. The base 1 is inserted into the upper flange 22. The inner wall surface of the upper flange 22 has a limit groove 224. The tolerance ring 3 is located in the limit groove 224, and the tolerance ring 3 is sleeved and abuts against the base 1. The upper and lower ends of the union nut 23 are respectively sleeved on the upper flange 22 and the lower flange 21. The base 1 will be inserted into the upper flange 22, so that the tolerance ring 3 will be limited in the limit groove 224. The limit groove 224 will limit the tolerance ring 3, effectively avoiding the deviation and dislocation of the tolerance ring 3 during use, ensuring that the tolerance ring 3 exerts a force on the base 1, and further improving the stability of the connector device.

[0054] In this embodiment, the union nut 23 is connected to the upper flange 22 by a first retaining spring 24 to realize rotational connection, and the union nut 23 is threadedly connected to the lower flange 21. The outer peripheral surface of the lower flange 21 has an external thread, and the lower flange 21 is threadedly connected to the union nut 23 by the external thread, so that the lower flange 21 can be disassembled for maintenance and replacement, and the installation and disassembly are very convenient; and after the lower flange 21 is disassembled, the lower flange 21 of different shapes and structures can be replaced, that is, different types of lower flanges 21 can be replaced to meet the installation and use requirements of different types of interfaces, so that the connector device can be widely used. At the same time, the union nut 23 is connected to the upper flange 22 by a first retaining spring 24, so that the union nut 23 and the upper flange 22 can rotate relative to each other, so that the union nut 23 can be rotated to facilitate installation and connection on the lower flange 21.

[0055] A stop ring 25 is pressed between the lower flange 21 and the union nut 23. The stop ring 25 is located below the external thread, and the union nut 23 is pressed onto the stop ring 25 after being threadedly connected to the external thread, effectively preventing the lower flange 21 and the union nut 23 from loosening, and providing a higher connection stability. The outer peripheral surface of the lower flange 21 has a stop ring groove, and the stop ring 25 is inserted into the stop ring groove, effectively preventing the stop ring 25 from being offset and dislocated during use, and providing a higher stability.

[0056] In this embodiment, the upper flange 22 is installed and connected to the base 1 through the second retaining spring 28, so that the upper flange 22 and the base 1 can rotate. Specifically, the tolerance ring 3 is pressed between the upper flange 22 and the base 1, and the tolerance ring 3 applies a force on the upper flange 22 and the base 1 to limit the rotational movement of the base 1. The second retaining spring 28 is installed on the outer peripheral surface of the base 1 and abuts against the upper flange 22, only blocking the upper flange 22 from moving in the radial direction away from the base 1 to prevent the upper flange 22 from detaching from the base 1, and the second retaining spring 28 allows the upper flange 22 to rotate on the base 1. When the base 1 needs to be rotated and adjusted, a tool can be used to apply a force on the base 1 to overcome the force applied by the tolerance ring 3 on the base 1 to achieve the rotational adjustment of the base 1.

[0057] The bottom of the upper flange 22 and / or the top of the lower flange 21 has at least one anti-rotation portion 211, and the anti-rotation portion 211 is used to prevent the upper flange 22 and the lower flange 21 from rotating. The upper and lower ends of the union nut 23 are respectively sleeved on the upper flange 22 and the lower flange 21, and the top of the lower flange 21 and the bottom of the upper flange 22 will exert a force on each other through the anti-rotation portion 211 to prevent the upper flange 22 and the lower flange 21 from rotating, so that the connection stability between the lower flange 21, the upper flange 22, the union nut 23 and the base 1 is higher, and the rotational movement between the lower flange 21 and the upper flange 22 is effectively avoided, so that the electrical connection is more stable and reliable.

[0058] In this embodiment, the anti-rotation part 211 is in the shape of teeth, and a plurality of anti-rotation parts 211 are respectively arranged around the bottom of the upper flange 22 and the top of the lower flange 21. The bottom of the upper flange 22 and the top of the lower flange 21 are meshed with each other through a plurality of tooth-shaped anti-rotation parts 211, so that the connection stability between the lower flange 21, the upper flange 22, the union nut 23 and the base 1 is higher. When the base 1 needs to be rotated and adjusted, the union nut 23 needs to be manually loosened so that the lower flange 21 and the upper flange 22 can move in a direction away from each other, so that the plurality of anti-rotation parts 211 meshed with each other up and down can be disengaged from each other, so that the rotation adjustment of the base 1 can be achieved, and the safety and stability are higher. At the same time, the anti-rotation part 211 is in the shape of teeth, so that the upper flange 22 and the lower flange 21 can be meshed within a small rotation range to exert a force on each other, so as to achieve fixation without rotational movement; and the structure is simple and very convenient to use. Of course, in other embodiments, the anti-rotation portion 211 may also adopt other structural forms, as long as the interaction force between the lower flange 21 and the upper flange 22 is achieved to prevent the rotational movement.

[0059] like Figure 2 and Figure 3As shown, a first sealing ring 26 is pressed between the upper flange 22 and the lower flange 21 , and the first sealing ring 26 effectively strengthens the sealing between the upper flange 22 and the lower flange 21 , thereby improving the safety and stability of the connector device.

[0060] A second sealing ring 27 is pressed between the upper flange 22 and the base 1 , and the second sealing ring 27 effectively strengthens the sealing between the upper flange 22 and the base 1 , further improving the safety and stability of the connector device.

[0061] Example 2

[0062] like Figure 4 As shown, the same parts of the connector device of this embodiment as those of the first embodiment will not be repeated, and only the differences will be described. In the first embodiment, the upper flange 22 is rotatably connected to the union nut 23 through the first retaining spring 24, and the union nut 23 is threadedly connected to the lower flange 21. In the second embodiment, the union nut 23 and the lower flange 21 are rotatably connected through the first retaining spring 24, and the union nut 23 and the upper flange 22 are threadedly connected.

[0063] Specifically, the outer peripheral surface of the lower flange 21 and the inner wall surface of the union nut 23 are both provided with a retaining ring groove, and the first retaining ring 24 is inserted into the two retaining ring grooves to realize the rotational connection between the lower flange 21 and the union nut 23. The outer surface of the upper flange 22 is provided with an external thread, and the union nut 23 is threadedly connected to the external thread. Among them, a stop ring 25 is pressed between the union nut 23 and the upper flange 22, and the stop ring 25 is located above the external thread.

[0064] Example 3

[0065] This embodiment also discloses a connector device, such as Figure 1 , Figure 2 and Figure 3 As shown, the connector device includes a base 1 and a flange component 2, the base 1 is inserted into the flange component 2 and can rotate in the flange component 2, the top of the flange component 2 has a rotating ring groove 221 and a positioning groove 222, and the outer surface of the base 1 has a positioning block 11; the positioning block 11 is located in the rotating ring groove 221 and can rotate in the rotating ring groove 221; or, the positioning block 11 is located in the positioning groove 222 to prevent rotation between the base 1 and the flange component 2.

[0066] Specifically, in this embodiment, the rotating annular groove 221 and the positioning groove 222 are located at the top of the upper flange 22. The rotating annular groove 221 and the positioning groove 222 are processed and manufactured on the top of the upper flange 22, and the positioning block 11 can be inserted into the rotating annular groove 221 or into the positioning groove 222. When assembling the connector device, when the use condition requires the base 1 to be rotated and adjusted, the base 1 is inserted into the upper flange 22, and the positioning block 11 is inserted into the rotating annular groove 221, so that the positioning block 11 can rotate and move in the rotating annular groove 221, that is, the base 1 can achieve a wide range of angle rotation adjustment in the upper flange 22 to meet the use requirements. When the base 1 does not need to be rotated and adjusted, the base 1 is inserted into the upper flange 22, and the positioning block 11 is inserted into the positioning groove 222, so that the positioning block 11 cannot rotate and move in the positioning groove 222, that is, the base 1 cannot rotate and move in the upper flange 22, thereby achieving the fixation of the base 1 and high electrical connection stability.

[0067] The top of the flange component 2 has two blocking members 223, which are arranged in the rotating annular groove 221 at intervals, and a positioning groove 222 is formed between the two blocking members 223. The positioning block 11 can be in the positioning groove 222, so that the two blocking members 223 abut against the rotation of the base 1. The two blocking members 223 are arranged in the rotating annular groove 221 at intervals, and the positioning groove 222 is formed by the space between the two blocking members 223.

When the base 1 does not need to be rotated and adjusted, the positioning block 11 will be arranged between the two blocking members 223, and the two blocking members 223 abut against the rotation of the base 1. When the base 1 needs to be rotated and adjusted, the positioning block 11 is inserted into the rotating annular groove 221, that is, the positioning block 11 is located in the space outside the two blocking members 223, so that the positioning block 11 can rotate in the rotating annular groove 221, that is, the base 1 can realize a wide range of angle rotation adjustment in the upper flange 22 to meet the use requirements.
