[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figure 1 As shown, in this solution, an auxiliary installation and protection structure for components used on an inverter is mainly described in detail, but the auxiliary installation and protection structure for components is not limited to being used in an inverter, and can also be applied to other devices using components.

[0025] like Figures 1 to 4 As shown, the utility model is an auxiliary installation and protection structure for components, the components include a magnetic ring 10 and a sensor 11, including: a protective member 2, on which an external guide cavity 20 and an internal protective cavity 21 are formed, the external guide cavity 20 is used to limit the movement of the copper bus 3 and guide the copper bus 3 to extend into the internal protective cavity 21; a first limiting portion 210 and a second limiting portion 211 are formed on the internal protective cavity 21 to communicate with each other, the first limiting portion 210 is used to support and limit the movement of the magnetic ring 10 relative to the copper bus 3, and cooperate with the second limiting portion 211 to hide the sensor 11 and the magnetic ring 10 in the internal protective cavity 21 to prevent external impurities from entering the internal protective cavity 21; an extension plate 4 is arranged on the two side walls of the external guide cavity 20 and the internal protective cavity 21, the extension plate 4 is used to connect the external shell 1 to limit the displacement of the protective member 2.

[0026] The embodiment is mainly aimed at the protection of the magnetic ring 10 and the sensor 11 on the inverter, and specifically, as shown in Figures 1 to 4 When the components need to be installed, first, the copper bar 3 is aligned with the external guide cavity 20 on the protection piece 2. The shape and size of the external guide cavity 20 are designed to match the copper bar 3, which can effectively guide the copper bar 3 to move along the predetermined path until the copper bar 3 is completely inserted into the internal protection cavity 21, effectively reducing the deviation in the installation process and improving the installation efficiency and quality. After the copper bar 3 is inserted into the internal protection cavity 21, the magnetic ring 10 and the sensor 11 are placed in the internal protection cavity 21. The double fixation design of the first limiting part 210 and the second limiting part 211 ensures the stability and reliability of the magnetic ring 10 and the sensor 11 during use, reducing the risk of displacement due to vibration or impact. Because of the close fit of the internal protection cavity 21 and the components, the normal operation of the components connected to the copper bar 3 and other components in the inverter is ensured, and the intrusion of external impurities is effectively blocked, prolonging the service life of the components. Finally, the extension plate 4 is fixed on the shell 1 by bolts or other fasteners to ensure the stability of the protection piece 2 during installation and use. As can be seen, the overall structure has the functions of auxiliary installation and protection of components. Through reasonable layout design, the installation process is simpler, and the long-term operation of the components in the inverter is effectively ensured.

[0027] The external guide cavity 20 is also provided with symmetrically arranged guide grooves 200, and the protection piece 2 is also provided with a through hole 22 for connecting the guide grooves 200, the first limiting part 210 and the second limiting part 211. When the copper bar 3 is placed in the guide groove 200, it can pass through the through hole 22 and extend into the internal protection cavity 21.

[0028] As shown in Figure 1 , Figure 2 and Figure 4 , the design of the through hole 22 can connect the guide groove 200 and the internal protection cavity 21. When the copper bar 3 is placed in the guide groove 200, the guide groove 200 can limit the width direction of the copper bar 3, and at the same time guide the length direction (i.e. the predetermined path) of the copper bar 3 to move. With the advancement of the copper bar 3, the copper bar 3 can pass through the through hole 22 on the protection piece 2 and finally extend into the internal protection cavity 21 to complete the connection with the components. This structure is beneficial to simplify the installation steps of the operator, reduces the skill requirement of the operator, and ensures the precise alignment and insertion of the copper bar 3 through the symmetrically arranged guide grooves 200 and the design of the through hole 22, reducing the deviation in the installation process, improving the installation efficiency and quality, and avoiding the deflection or jamming phenomenon of the copper bar 3 during insertion.

[0029] Preferably, the embodiment also opens a U-shaped groove 200a at the bottom of the guide groove 200, as shown in Figure 4As shown, the opening of the U-shaped groove 200a faces the built-in protection cavity 21, and in the installation process, the copper bar 3 is connected with a guide (not shown in the figure), which is movably clamped in the U-shaped groove 200a, and cooperates with the guide groove 200 to guide and limit the copper bar 3, which can ensure that the copper bar 3 is stably connected with the components along the specified position, and can prevent the copper bar 3 from accidentally separating from the guide groove 200 during the installation process.

[0030] The middle position of the external guide cavity 20 is also formed with a reinforcing block 201, which is connected to the outer wall of the built-in protection cavity 21, and the mounting hole 201a is formed on the reinforcing block 201, which can be passed through by the fixing member.

[0031] As Figure 2 shown, the reinforcing block 201 in the embodiment is composed of a cylindrical block and two rectangular plates, and one of the rectangular plates is connected to the outer wall of the built-in protection cavity 21, which not only improves the structural strength of the external guide cavity 20, but also provides protection for the stability of the built-in protection cavity 21 when it hides the components. Moreover, in the installation process, the fixing member is passed through the mounting hole 201a in the reinforcing block 201 and is fixed on the external shell 1 or other support structure, which ensures the stability of the two-sided guide groove 200 during the installation and use of the copper bar 3.

[0032] The first limiting part 210 is composed of a first circular surface 210a and a second circular surface 210b, and the protection member 2 is provided with a support block 23, which extends into the magnetic ring 10, so that the outer wall of the magnetic ring 10 can be tightly attached to the first circular surface 210a and the second circular surface 210b; the second limiting part 211 is provided with a support frame 211a, and the top end of the support frame 211a is an L-shaped limiting groove 211b, and the top end of the L-shaped limiting groove 211b is connected with the second circular surface 210b, which is used to limit the movement of the sensor 11.

[0033] As Figure 1 and Figure 3As shown, the design of the support block 23 enables the outer wall of the magnetic ring 10 to fit tightly against the first arc surface 210a and the second arc surface 210b, thereby fixing the position of the magnetic ring 10 and preventing it from being displaced relative to the copper busbar 3 and affecting the accuracy and stability of the connection; not only that, as the copper busbar 3 passes through the through hole 22 from the above-mentioned guide groove 200 and extends into the first limiting portion 210 or the second limiting portion 211, the support block 23 can provide a certain supporting effect on the copper busbar 3, avoiding the copper busbar 3 from being misplaced and affecting the installation accuracy; in addition, the design of the support frame 211a is conducive to enhancing the overall structural strength of the second limiting portion 211, while also being able to utilize the formed L-shaped limiting groove 211b to provide better support and limiting effect on the installation of the sensor 11, ensuring that the magnetic ring 10 and the sensor 11 do not interfere with each other, thereby achieving stable operation of the inverter.

[0034] The top ends of the first limiting portion 210 and the second limiting portion 211 are both formed with avoidance openings 240. The copper busbar 3 extending from the guide groove 200 can be placed on the support block 23 to stably contact the copper busbar 3 connected to the sensor 11, so that the locking member can pass through the avoidance opening 240 and connect the two copper busbars 3.

[0035] like Figure 3 As shown, the side openings of the first limiting portion 210 and the second limiting portion 211 in this embodiment are both facing other components inside the inverter, which is conducive to the installation and connection of the copper busbar 3, and also provides a certain degree of protection for the magnetic ring 10 and the sensor 11. The reason why the avoidance openings 240 are opened above the two limiting portions is that the copper busbar 3 connecting the magnetic ring 10, the copper busbar 3 connecting the sensor 11, and the copper busbar 3 extending from the inside of the inverter need to be connected with each other. Therefore, without affecting the hidden protection of the magnetic ring 10 and the sensor 11, the avoidance opening 240 is just above the connection between the two copper busbars 3, so that workers can smoothly reach in through the locking piece and connect and fix the copper busbars 3, which provides great convenience for the installation operation and thus improves work efficiency.

[0036] Preferably, in the above-mentioned installation process, the extension plate 4 is arranged in an L-shape in this embodiment, and the connection hole 40 opened on the bottom wall of the extension plate 4 can be used to again realize the stable connection between the protective part 2 and the external shell 1 through bolts, screws and other structures, thereby further improving the firmness of the overall structure during installation and use.

[0037] It should be noted that the fixing member and the locking member in this embodiment can be replaced by other connecting members such as bolts and screws.

[0038] It should be noted that all directional indications (such as upper, lower, left, right, front, rear, etc.) in the embodiments of the present application are only used to explain the relative position relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.
