[0002] With the increasing frequency conversion of air conditioners, electromagnetic compatibility requirements are becoming increasingly stringent. Adding magnetic rings to the wiring within the unit is a primary means of suppressing electromagnetic interference. However, existing magnetic ring structures are relatively independent, and after winding, the magnetic rings are typically tightened with wire ties or heat shrink tubing. However, due to the prevalence of multiple magnetic rings being wound together, tightening with heat shrink tubing is difficult and costly. Furthermore, the shape of the magnetic rings after winding is irregular, making them difficult to secure with wire ties and requiring high consistency in production operations. Furthermore, it is common for the magnetic rings to be secured together with other wiring, which creates limited space and makes operation difficult, a major pain point for production inefficiency.

DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0037] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figure 1 As shown, the present invention provides a magnetic ring fixing device, including a magnetic ring mounting base 1, which is used to mount a magnetic ring 2 and confine the magnetic ring 2 within the magnetic ring mounting base 1. At least two sets of positioning clips 11 are spaced apart along the outer peripheral sidewall of the magnetic ring mounting base 1. The positioning clips 11 are formed with a snap-in opening 12 on the outer side away from the magnetic ring mounting base 1. One of the at least two sets of positioning clips 11 allows a pipeline to be snapped into the snap-in opening 12 to fix the magnetic ring mounting base 1, and the other set of the at least two sets of positioning clips 11 allows a wire to be snapped into the snap-in opening 12 for routing.

[0040] The magnetic ring fixing device of the present invention is multifunctional. By setting at least two groups of positioning buckles 11 at intervals on the outer peripheral side wall of the magnetic ring mounting base 1, and forming a card entrance 12 on the outer side of the positioning buckle 11 away from the magnetic ring mounting base 1, on the one hand, the magnetic ring mounting base can be directly fixed on the pipeline through the positioning buckle to achieve the fixation of the magnetic ring mounting base and the magnetic ring. There is no need to set additional components for the installation position, and there is no need for wire ties for fixing. This solves the problem of high wire tie fixing requirements and also saves fixed wire ties. By making the magnetic ring fixing device have its own fixing method, the production efficiency can be improved by 30% compared with the traditional wire tie fixing method. At the same time, the positioning buckles of the remaining groups of the magnetic ring fixing device of the present invention also allow the wires to be clipped in for wiring, which can achieve rapid fixation of the wiring.

[0041] More preferably, Figure 3 As shown, at least two sets of positioning clips 11 comprise four sets spaced apart along the outer sidewall of the magnetic ring mounting base 1, with adjacent sets of positioning clips 11 spaced 90° apart. One set of positioning clips 11 is used to snap the pipeline into place, thereby securing the magnetic ring mounting base and the magnetic ring. The remaining three sets of positioning clips can be used for internal wiring. The positioning clips spaced at angles can also be used to separate strong and weak current wiring, significantly improving the electromagnetic compatibility performance of the unit.

[0042] More preferably, Figures 1 to 3As shown, the positioning clip 11 includes two relatively arranged clips 111. The clip 111 includes a first limiting member 112 and a second limiting member 113. The first limiting member 112 and the second limiting member 113 are arranged at an acute angle, and the second limiting member 113 is arranged horizontally. The end of the first limiting member 112 away from the second limiting member 113 is fixed to the outer peripheral side wall of the magnetic ring mounting base 1, and the second limiting members 113 of the two relatively arranged clips 111 are arranged opposite to each other. Therefore, the spacing distance between the two first limiting members 112 in the positioning clip 1 at the end connected to the magnetic ring mounting base 1 is smaller than the spacing distance at the end away from the magnetic ring mounting base 1, that is, the slot width formed by the clip 111 gradually increases from the magnetic ring mounting base 1 to the outside, and the outermost side of the slot is limited by the second limiting member 113 to clip and fix the pipeline or wire.

[0043] Preferably, the snap-in opening 12 is the distance between the two oppositely positioned second retaining members 113, and this distance is smaller than the diameter of the pipe or wire. This allows the pipe or wire to be inserted into the positioning buckle through the snap-in opening 12 and is not easily removed from the snap-in opening. Preferably, the second retaining member 113 has two inclined surfaces at the end away from the first retaining member 112, with the two inclined surfaces facing outward and toward the interior of the snap-in slot, respectively, to facilitate the insertion of the pipe or wire or its removal from the positioning buckle, thus facilitating operation.

[0044] More preferably, Figures 1 to 3 As shown, the first limiting member 112 is a truncated cone structure, and the large diameter end of the first limiting member 112 is fixed to the outer peripheral side wall of the magnetic ring mounting base 1 to increase the stability of the positioning buckle.

[0045] More preferably, Figure 1 or Figure 2 As shown, an anti-sliding block 13 is provided on the outer peripheral side wall of the magnetic ring mounting base 1, and the anti-sliding block 13 is provided corresponding to the position of each group of positioning buckles 11. Preferably, the anti-sliding block 13 can be a rubber block. When the pipeline is inserted into the positioning buckle, the rubber block can increase the friction with the pipeline so that the pipeline will not slide off. Preferably, each group of positioning buckles 11 includes at least two arranged on the outer peripheral side wall of the magnetic ring mounting base 1 and along the axial direction of the magnetic ring mounting base 1. Preferably, the anti-sliding block 13 is provided on the outer peripheral side wall near the bottom of the magnetic ring mounting base 1, so that the fixation of the magnetic ring fixing device to the pipeline is more stable.

[0046] More preferably, see Figures 1 to 3A limiting slot 14 is formed at the top of the outer side wall of the magnetic ring mounting base 1 and corresponds to the position of each set of positioning buckles 11. The limiting slot 14 is a long strip structure with an open top. The limiting slot 14 is formed on the side wall of the magnetic ring mounting base 1 and is used to quickly position the magnetic ring through the limiting slot 14 after the magnetic ring is wound to prevent it from loosening. Preferably, the limiting slot 14 is set in the middle of the positioning buckle near the top, so that the wire can be positioned in the limiting slot after the magnetic ring is wound and then routed through the positioning buckle.

[0047] More preferably, Figure 2 As shown, the interior of the magnetic ring mounting base 1 is provided with a limiting cavity 15 for limiting the magnetic ring 2. The limiting cavity 15 and the magnetic ring 2 are concentric circles and are used to install the magnetic ring 2. When in use, a magnetic ring of appropriate size can be selected and installed according to the actual impedance requirements. Preferably, a cover plate 16 that can open or close the limiting cavity 15 is provided on the top of the limiting cavity 15, such as Figure 2 A bottom plate 17 is fixedly provided at the bottom of the limiting cavity 15. Figure 4 After the magnetic ring 2 is installed in the limiting cavity of the magnetic ring mounting seat, the cover 16 is closed to protect the internal magnetic ring.

[0048] Preferably, if Figure 2 and Figure 4 As shown, both the cover plate 16 and the base plate 17 are formed with through-holes 18 for allowing wires to pass through. Through-holes 18 include a circular hole 181 located in the center of the cover plate 16 or base plate 17 and an elongated hole 182 connected to the circular hole 181. The elongated hole 182 extends radially along the cover plate 16 or base plate 17. Through-holes 18 are used to facilitate wiring.

[0049] Further preferably, one end of the cover 16 is connected to the side wall of the magnetic ring mounting seat 1 through a hinge, so that the cover 16 is in an open or closed state through the hinge, and the other end of the cover 16 away from the hinge is connected to the top of the side wall of the magnetic ring mounting seat 1 through a magnetic attraction component. Therefore, when the cover 16 is closed, the cover can be fixed to the top of the side wall of the magnetic ring mounting seat through the magnetic attraction component, and when the cover 16 is opened, the magnetic attraction component is separated, and the cover 16 is opened under the action of the hinge, which facilitates the replacement of the magnetic ring. Specifically, as Figures 5 to 8 As shown, the hinge comprises a connecting block 21 and a rotating shaft 19. The rotating shaft 19 is fixed to the connecting block 21 and both ends of the rotating shaft 19 extend out of the connecting block 21. Figure 8 As shown. A mounting hole 22 is provided at the top of the outer peripheral side wall of the magnetic ring mounting base 1. The mounting hole 22 matches the shape of the connecting block 21. Guide rails 20 for sliding the rotating shaft 19 are provided on both side walls of the mounting hole 22. Figure 7As shown, the guide rail 20 is a groove structure recessed in the side wall of the mounting hole. During installation, the connecting block 21 is placed in the mounting hole 22, and the two ends of the rotating shaft 19 are placed in the guide rail 20. When the cover is in the closed state, the two ends of the rotating shaft 19 are located in the upper part of the groove in the guide rail 20, as shown in FIG. Figure 5 When the cover is flipped, the rotating shaft 19 slides to the lower part of the groove of the guide rail 20, so that the cover is flipped to a certain angle and stuck, keeping it in the open state, as shown in FIG. Figure 6 shown.

[0050] More preferably, Figure 9 As shown, the magnetic assembly includes a magnet embedded in the cover 16 and an iron block embedded in the magnetic ring mounting base 1. The position of the iron block on the magnetic ring mounting base 1 corresponds to the position of the magnet on the cover 16 to achieve the opening or closing of the cover. Preferably, the magnetic assembly is located at the end away from the hinge.

[0051] The specific installation method of the magnetic ring fixing device of the present invention is as follows:

[0052] The wiring harness uses anti-interference testing to identify frequency points that do not meet the test requirements. Iron cores of different magnetic permeabilities are selected based on the impedance characteristics. The magnetic ring is placed in the magnetic ring fixture, and the wiring harness is wound around the magnetic ring a certain number of times. The position is fixed by the retaining clips, and the cover is closed to form a complete protection. Based on the interference source, the wiring harness of the interference source is routed independently using the positioning clips. The remaining wires are separated using other positioning clip routing methods to achieve the purpose of separating strong and weak wires.

[0053] The magnetic ring fixing device of the present invention is convenient for fixing the magnetic ring, and the magnetic ring fixing device has its own positioning buckle, which solves the problem of high requirements for wire tie fixation. It also facilitates wiring and can realize separate wiring of strong and weak electricity. It has high consistency and convenient operation, and improves the electromagnetic compatibility performance and production efficiency of the unit.

[0054] Example 2

[0055] The present invention further provides an air conditioner, comprising the magnetic ring fixing device described in Example 1, wherein the magnetic ring fixing device is fixed to the pipeline of the air conditioner via a positioning clip 11. The air conditioner of the present invention can directly fix the magnetic ring fixing device to the pipeline via the positioning clip without requiring additional steps, thereby improving the electromagnetic compatibility performance and production efficiency of the unit.
