[0062] Some typical embodiments of the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different ways, all of which do not depart from the scope of the present invention, and the descriptions and drawings therein are essentially for illustrative purposes and not for limiting the present invention.
[0063] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented on the premise of the technical solution of the present invention, and the implementation manners and operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.
[0064] Please refer to Figure 1 、 Figure 2 、 Figure 3A and Figure 3B . Figure 1 Schematic diagram showing a current transformer fixing device according to an embodiment of the present invention. Figure 2 Showing Figure 1 Schematic diagram of the combination of the current transformer fixing device in Figure 3A with a current transformer having a channel and a conductor passing through the channel of the current transformer. Figure 2 Front view of the combination in Figure 3B Showing Figure 2 Side view of the combination in . In this embodiment, the current transformer fixing device 10 is used to be combined with a current transformer 20 having a channel 21 to support a conductor 30 passing through the channel 21 of the current transformer 20, and the channel 21 has a rectangular shape. The current transformer fixing device 10 includes a base 11, a plurality of first limiting elements 12, a plurality of second limiting elements 13, an opening 14 and a guiding element 15. The base 11 includes a first surface 111 and a second surface 112 opposite to each other. The first limiting elements 12 and the guiding element 15 are disposed on the base 11, the second limiting elements 13 are respectively disposed on the corresponding first limiting elements 12, and the opening 14 is formed on the base 11. The first limiting elements 12 extend from the first surface 111 of the base 11 in a direction substantially parallel to the normal of the first surface 111, that is, in the X-axis direction of the current transformer 20, so that a space 16 is formed between the plurality of first limiting elements 12. The opening 14 is substantially located in the middle of the first limiting elements 12, that is, at a position corresponding to the space 16. The guiding element 15 is disposed adjacent to the opening 14 and extends in a direction substantially parallel to the normal of the first surface 111, so that the guiding element 15 is located in the space 16 and is substantially parallel to the first limiting elements 12. In some embodiments, the guiding element 15 can be implemented to extend from one surface of the base 11 (that is, the first surface 111) in a direction substantially the same as that of the first limiting elements 12; in other embodiments, the guiding element 15 can also be implemented to extend from the opposite surfaces of the base 11 (that is, the first surface 111 and the second surface 112) to form a form passing through the base 11. Each of the second limiting elements 13 is disposed at the distal end of the corresponding first limiting element 12 relative to the base 11, and extends from the corresponding first limiting element 12 in a direction away from the space 16 and is substantially parallel to the first surface 111 of the base 11.
[0065] When the current transformer fixing device 10 is combined with the current transformer 20, the space 16 of the current transformer fixing device 10 corresponds to the channel 21 of the current transformer 20, and the first limiting element 12 and the guiding element 15 of the second limiting element 13 will pass through the channel 21. Accordingly, the first surface 111 of the base 11 will abut against the third surface 22 of the current transformer 20, the first limiting element 12 will abut against the inner edge surface 211 of the channel 21 of the current transformer 20, and the second limiting element 13 will abut against the fourth surface 23 of the current transformer 20 opposite to the third surface 22. In this configuration, on the one hand, by the mutual abutment between the first limiting element 12 and the inner edge surface 211 of the channel 21, the current transformer fixing device 10 can be maintained in the channel 21 of the current transformer 20. That is to say, the position of the current transformer 20 relative to the current transformer fixing device 10 in the Y-Z plane can be fixed thereby; on the other hand, by the second limiting element 13 abutting against the fourth surface 23, the relative positional relationship between the current transformer fixing device 10 and the current transformer 20 can be further defined. That is to say, the position of the current transformer fixing device 10 relative to the current transformer 20 in the X-axis direction can be fixed thereby. In addition, the opening 14 will be located at a position corresponding to the channel 21, and the guiding element 15 will be suspended in the channel 21.
[0066] Preferably, the first limiting element 12 and / or the second limiting element 13 can be bent when the current transformer fixing device 10 passes through the channel 21, and then rebound to abut against the inner edge surface 211 and / or the fourth surface 23 of the current transformer 20, so as to position the current transformer fixing device 10 in the channel 21 thereby.
[0067] Preferably, the first limiting element 12 can be configured in a paired form, and each pair of the first limiting elements 12 is arranged at opposite positions. In this way, the paired first limiting elements 12 can abut against the opposite positions of the inner edge surface 211 of the channel 21, providing supporting forces in opposite directions, and further making the current transformer fixing device 10 more stable in the channel 21. For example, as Figure 3A shown, the first limiting elements 12 can be respectively arranged at opposite positions on the four sides of the rectangular channel 21. For example, one pair is arranged in the Z-axis direction, and the other pair is arranged in the Y-axis direction; or as Figure 4 shown, the first limiting elements 12 can also be respectively arranged at the four corners of the rectangular channel 21 and opposite to each other. For example, both pairs are arranged in the Z-axis direction, or both pairs are arranged in the Y-axis direction.
[0068] The opening 14 is used for the conductor 30 to pass through. As Figure 2As shown, since the opening 14 reduces the range of the channel 21 of the current transformer 20, the movement of the conductor 30 passing through within the channel 21 can be reduced. Preferably, the shape of the opening 14 can be configured to match the outer surface of the conductor 30 to further define the position where the conductor 30 passes through the channel 21. For example, as Figure 3A shown, the cross-sectional shape of the conductor 30 is rectangular, and the opening 14 is also configured as a similar rectangular shape, thereby minimizing the movement of the conductor 30 within the channel 21. The guiding element 15 is used to guide the direction of the conductor 30 within the channel 21. In some embodiments, the guiding element 15 includes an extending element 151 extending from the first surface 111, and a fixing element 152 disposed at the distal end of the extending element 151 relative to the base 11. In some embodiments, the guiding element 15 includes an extending element 151 extending from the opposite surface of the base 11, and a fixing element 152 disposed at one or both ends of the extending element 151. When the conductor 30 passes through the opening 14, the extending element 151 can be bent, and the fixing element 152 moves on the surface of the conductor 30 until it is fixed to a corresponding fixing portion (not shown) on the conductor 30, thereby restricting the direction of the conductor 30 after passing through the opening 14. For example, the extending element 151 can be implemented as a rod for supporting the conductor 30, and the fixing element 152 can be implemented as a pin fixed within a hole on the conductor 30. Therefore, there can be various implementation manners without limitation.
[0069] Furthermore, the current transformer fixing device of the present invention can adapt to different shapes of the channels 21 of different current transformers by varying the number and positions of the first limiting elements 12. Please refer to Figure 5 、 Figure 6A and Figure 6B . Figure 5 A schematic diagram showing a current transformer fixing device according to another embodiment of the present invention.
[0070] Figures 6A to 6B Show Figure 5 A schematic diagram showing the combination of the current transformer fixing device in Figure 1 with a current transformer having a channel and a conductor passing through the channel of the current transformer respectively. In this embodiment, different from the embodiment shown in Figure 5 shown, the current transformer fixing device 10a includes two first limiting elements 12 and two second limiting elements 13. For example, as Figure 6AAs shown, the current transformer fixing device 10a can be combined with a current transformer 20a having a circular-shaped channel 21a. Advantageously in this application example, the current transformer fixing device 10a can move along the Y-Z plane, that is to say, move along the inner edge surface 211a of the channel 21a, to adapt to the different setting orientation requirements of a conductor 30 with a rectangular cross-sectional shape. In another application example, as Figure 6B shown, the current transformer fixing device 10a can be combined with a current transformer 20b having a stepped-shaped channel 21b. In this application example, when necessary, the current transformer fixing device 10a can rotate 90 degrees along the Y-Z plane to adapt to the different setting orientation requirements of a conductor 30 with a rectangular cross-sectional shape. Therefore, the current transformer fixing device 10a provides the use flexibility to adapt to different-shaped channels of current transformers. Of course, Figure 1 and Figure 4 the current transformer fixing device 10 shown in Figure 1 and Figure 4 and Figure 5 can also be combined with current transformers 20a, 20b as long as the position and / or shape of the first limiting element 12 can match the shapes of the channels 21a, 21b, without limitation. For example, the first limiting element 12 (as shown in Figure 6A ) can be formed as an arc-shaped element to match the circular shape of the channel 21a of the current transformer 20a, as shown in Figure 6B ; or the first limiting element 12 can also be formed at the position where the shape of the channel 21b of the corresponding current transformer 20b changes, as shown in
[0071] Figures 7A to 7B Figures 7A to 7BAs shown, the corresponding conductor 30c is a cable or rod with a circular cross-section, which can provide a current transformer fixing device 10c. Among them, the opening 14c is configured to have a similar circular shape to limit the movement of the passing conductor 30c, and the guiding element 15c is respectively configured as an arc-shaped element. For example, two arc-shaped elements opposite to each other are used to surround the outer surface of the conductor 30c, and then the direction of the conductor 30c is guided by clamping or friction. In an embodiment, the current transformer fixing device 10c further includes a surrounding structure 141c protruding from the second surface 112 of the base 11 to form the opening 14c, and cooperates with the guiding element 15c to further limit the direction of the passing conductor 30c in the channel 21. In other embodiments, according to different actual requirements, it can also be implemented without limitation by using a single guiding element 15c or more than two guiding elements 15c to match the circular outer surface of the conductor. In other embodiments, the guiding element can be configured as any structure that can provide clamping and / or friction functions, such as a clamp, a cable tie or a gland, etc., without limitation. Therefore, the number and detailed structure of the guiding element and the shape of the opening can all be changed without limitation according to actual requirements to achieve the purpose of fixing and / or supporting the conductor.
[0072] In another aspect of the present invention, the current transformer fixing device can be implemented in other forms. Figure 8 A schematic diagram showing a current transformer fixing device according to another embodiment of the present invention, and Figure 9 show Figure 8The combination of a current transformer fixing device, a current transformer having a channel, and a conductor passing through the channel of the current transformer. In this embodiment, the current transformer fixing device 10d is combined with the current transformer 20 having the channel 21 to support the conductor 30 passing through the channel 21. The current transformer fixing device 10d includes a first base 11d, a second base 17d, a plurality of first limiting elements 12d, an opening 14, and a guiding element 15. The first base 11d and the second base 17d are substantially parallel to each other, and the second base 17d is adjacent to the first surface 111d of the first base 11d. The first limiting elements 12d are disposed between the first base 11d and the second base 17d and are respectively connected to the two bases, thereby forming a space 16d between the plurality of first limiting elements 12d. The opening 14d is formed in the first base 11d at a position corresponding to the space 16d. The guiding element 15 is disposed on the first base 11d and suspended in the space 16d, and its extending direction is substantially parallel to the extending direction of the first limiting elements 12d. In some embodiments, the guiding element 15 can be implemented to extend from the first surface 111d of the first base 11d toward the second base 17d; in some embodiments, the guiding element 15 can also be implemented to extend from opposite two surfaces of the first base 11d, that is, extending toward and away from the second base 17d to form a form passing through the first base 11d. The second base 17d includes a hollowed-out portion 171d, which is substantially disposed at a position corresponding to the space 16d. Therefore, the opening 14 and the guiding element 15 can be exposed due to the hollowed-out portion 171d. In one embodiment, the first base 11d, the first limiting elements 12d, and the guiding element 15 are implemented as an integrally formed single-piece structure and are combined with the second base 17d to form the current transformer fixing device 10d; in another embodiment, the first base 11d and the guiding element 15 are implemented as an integrally formed single-piece structure, the first limiting elements 12d and the second base 17d are implemented as an integrally formed single-piece structure, and the two are combined with each other to form the current transformer fixing device 10d; in other embodiments, the current transformer fixing device 10d can also be formed in other ways, without limitation.
[0073] When the current transformer fixing device 10d is combined with the current transformer 20, the first surface 111d of the first base 11d abuts against the third surface 22 of the current transformer 20, the second base 17d abuts against the fourth surface 23 of the current transformer 20 opposite to the third surface 22, and the first limiting element 12d passes through the channel 21 of the current transformer 20 and abuts against the inner edge surface 211 of the channel 21 of the current transformer 20. Accordingly, the current transformer 20 is restricted between the first base 11d and the second base 17d, the position of the opening 14 falls within the range of the channel 21, and the guiding element 15 is suspended in the channel 21. In this configuration, on the one hand, the position of the current transformer fixing device 10d relative to the current transformer 20 in the Y-Z plane can be maintained by the mutual abutment between the first limiting element 12d and the inner edge surface 211 of the channel 21; on the other hand, the relative positional relationship between the current transformer fixing device 10d and the current transformer 20 in the X-axis direction can be fixed by the first base 11d and the second base 17d. In other words, the second base 17d provides a function similar to that of the second limiting element 13 in the previous embodiment.
[0074] The opening 14 is for the conductor 30 to pass through. As Figure 9 shown, since the opening 14 reduces the range of the channel 21 of the current transformer 20, the movement of the passing conductor 30 in the channel 21 can be reduced. Preferably, the shape of the opening 14 can be configured to match the outer surface of the conductor 30 to further define the position of the conductor 30 passing through the channel 21. For example, when the cross-sectional shape of the conductor 30 is rectangular, the opening 14 can be configured as a similar rectangular shape to minimize the movement of the conductor 30 in the channel 21. The guiding element 15 is used to guide the direction of the conductor 30 in the channel 21. In some embodiments, the guiding element 15 includes an extending element 151 extending from the first surface 111d of the first base 11d and facing the second base 17d, and a fixing element 152 disposed at the distal end of the extending element 151 relative to the first base 11d. In some embodiments, the guiding element 15 includes an extending element 151 extending from the opposite surface of the first base 11d, and a fixing element 152 disposed at one or two ends of the extending element 151. When the conductor 30 passes through the opening 14, the extending element 151 can be bent, and the fixing element 152 moves on the surface of the conductor 30 until it is fixed to the corresponding fixing portion (not shown) on the conductor 30, thereby restricting the direction of the conductor 30 after passing through the opening 14. For example, the extending element 151 can be implemented as a rod for supporting the conductor 30, and the fixing element 152 can be implemented as a pin fixed in a hole on the conductor 30. Therefore, there can be various implementation manners without limitation. In addition, the conductor 30 passing through the opening 14 and guided by the guiding element 15 further passes through the hollow portion 171d of the second base 17d to complete the procedure of passing through the channel 21.
[0075] The number and position of the first limiting element 12d can vary according to actual requirements. For example, it can be implemented as two or four first limiting elements 12d (similar to the embodiments shown in Figure 1 , Figure 4 and Figure 5 ), and are arranged in pairs at opposite positions to accommodate channels of different shapes of different current transformers.
[0076] Furthermore, the opening and guiding elements of the current transformer fixing device can also vary to accommodate conductors passing through current transformers of different types. In one embodiment, as shown in Figures 10A to 10B , for a corresponding conductor 30e being a cable or rod having a circular cross-section, a current transformer fixing device 10e can be provided, where the current transformer fixing device 10e includes a first base 11e, a second base 17e, a plurality of first limiting elements 12e, an opening 14e, and a guiding element 15e. The current transformer 20 is restricted between the first base 11e and the second base 17e, the opening 14e is configured to have a similar circular shape to restrict the movement of the passing conductor 30e, and the guiding elements 15e are respectively configured as arc-shaped elements to surround the outer surface of the conductor 30e, thereby guiding the direction of the conductor 30e through clamping or friction. In one embodiment, the current transformer fixing device 10e further includes a surrounding structure 141e protruding from the second surface 112e of the first base 11e to form the opening 14e, and cooperates with the guiding element 15e to further restrict the direction of the passing conductor 30e in the channel 21. In other embodiments, according to different actual requirements, it can also be implemented without limitation as using a single guiding element 15e or more than two guiding elements 15e to match the circular outer surface of the conductor. In other embodiments, the guiding element can be configured as any structure that can provide clamping and / or friction functions, such as a clamp, a cable tie, or a gland, etc., without limitation. Therefore, the number and detailed structure of the guiding element and the shape of the opening can all vary without limitation according to actual requirements to achieve the purpose of fixing and / or supporting the conductor.
[0077] In summary, the current transformer fixing device of the present invention can be combined into the channel of the current transformer in a self-aligning manner without the need to use additional fixing elements, and supports the conductor passing through the channel of the current transformer. Thus, not only can the load of manual inspection be reduced and the manufacturing cost be lowered, but also the impact and vibration transmitted from the conductor to the current transformer can be minimized to the greatest extent.
