Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connecting wire for a magnetic bearing controller. Background Art

[0002] In a magnetic bearing system, the magnetic bearing controller is the core part, which is responsible for receiving signals from displacement sensors, calculating the control current accordingly, and then sending the control current to the electromagnet through a power amplifier to generate the required magnetic force to achieve stable suspension of the rotor. The connecting wire plays a bridging role in this system;

[0003] The existing processing method currently has the following problems: Since the nut and the male head are separate, when locking the nut, a screwdriver socket tool is used to lock the nut and the stud on the fixing cylinders at both ends of the DB15PIN. Due to the small size of the nut and it being an individual part, after the stud passes through the plug fixing cylinder, the nut needs to be manually screwed on and fixed with a hexagonal socket, and then the hexagonal stud is tightened with a hexagonal socket. This seriously affects production efficiency, and both the installation and disassembly processes require turning the stud, and the disassembly is time-consuming.

[0004] Therefore, the utility model proposes a connecting wire for a magnetic bearing controller. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] This embodiment provides a technical solution. As Figures 1 to 4 shown, a connecting wire of a magnetic bearing controller includes a plug rear shell 1 and a plug soldering cup 11 fixedly connected to the bottom of the plug rear shell 1. A transmission assembly 2 is provided on the plug rear shell 1;

[0032] The transmission assembly 2 includes an arc-shaped connecting piece 22. A first universal ball 23 is fixedly connected to the arc-shaped connecting piece 22. One end of the arc-shaped connecting piece 22 far from the first universal ball 23 is fixedly connected to a second universal ball 25. A guiding column 24 is fixedly connected to the arc-shaped connecting piece 22;

[0033] In the present invention, by providing a chassis 3 and a sliding groove, the sliding groove provides a guiding function for the transmission of the guiding column 24, so that it will not fall off when driving the fixed cylinder 31 to reset. This design improves the stability and reliability of the connecting wire, ensures smooth connection and disassembly during use, thereby reducing the operation difficulty and improving the work efficiency, and solving the problem that both the installation and disassembly processes in the background technology require screwing the stud and the disassembly is time-consuming.

[0034] Furthermore, as Figures 1 to 4 shown, a chassis 3 is provided on the guiding column 24. A guiding groove is opened on the chassis 3. The guiding column 24 is slidably connected in the sliding groove on the chassis 3. By providing the chassis 3 and the sliding groove, the sliding groove provides a guiding function for the transmission of the guiding column 24, so that it will not fall off when driving the fixed cylinder 31 to reset;

[0035] A first rotating shaft 27 is rotatably connected to the bottom of the chassis 3. A grip disc 26 is fixedly connected to the bottom of the first rotating shaft 27. A connecting groove is opened on the grip disc 26. The first universal ball 23 is arranged in the connecting groove on the grip disc 26. By providing two universal balls, a fault tolerance function can be achieved between the arc-shaped connecting piece 22 and the grip disc 26, avoiding breaking the connection part of the arc-shaped connecting piece 22 when the grip disc 26 rotates;

[0036] Two fixing cylinders 31 are fixedly connected to the top of the chassis 3. One of the two fixing cylinders 31 on the side far from the second universal ball 25 is fixedly connected to the plug rear shell 1. By dividing the fixing cylinder 31 into two halves, one half is fixed to the plug rear shell 1 and the other half can be driven by the arc-shaped connecting piece 22 to realize the disassembly of the fixing cylinder 31, and the external thread 32 can be quickly disassembled.

[0037] One of the fixing cylinders 31 near the second universal ball 25 in the two fixing cylinders 31 is fixedly connected to the second universal ball 25. An external thread 32 is threadedly connected inside the fixing cylinder 31. A nut 43 is fixedly connected to the external thread 32. A second rotating shaft 42 is rotatably connected to the nut 43. A connecting member 41 is rotatably connected to the second rotating shaft 42. The connecting member 41 is fixedly connected to the front plug housing 4. By providing the external thread 32 and the fixing cylinder 31, the thread length inside the fixing cylinder 31 is 4 millimeters, and the thread length of the external thread 32 is 6 millimeters. In this way, there is an effective engagement of 4 millimeters of threads between the external thread 32 and the fixing cylinder 31 for the locking part. It is smooth and convenient for the user to screw it off during use.

[0038] There is also a problem that the strength may not be enough after the front plug housing 4 and the rear plug housing 1 are connected in the above solution. For example, Figures 1 to 3 As shown, a plug housing concave point 12 is fixedly connected to the rear plug housing 1. A plug housing convex point 44 is slidably connected to the plug housing concave point 12. The plug housing convex point 44 is fixedly connected to the front plug housing 4. By providing the concave point and the convex point, when in use, first engage the concave and convex points together, so that the front plug housing 4 and the rear plug housing 1 are connected more tightly.

[0039] Working principle:

[0040] As Figures 1-4 shown: When in use, first align the plug housing convex point 44 with the plug housing concave point 12 to connect them together. Then, rotate the grip disc 26 by an external force, so that the guide post 24 on the arc-shaped connecting member 22 slides in the guide groove on the chassis 3, causing the two fixing cylinders 31 to approach each other. After that, push the external thread 32 on the nut 43 onto the fixing cylinder 31 by an external force, and screw the nut 43 to gradually screw the external thread 32 into the fixing cylinder 31, then the connection between the rear plug housing 1 and the front plug housing 4 can be realized. At this time, the magnetic bearing controller connecting wire is ready for use and can be connected to the corresponding equipment through the plug welding cup 11 for operation.

[0041] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
