[0037] The following is combined with the attached Figure 1-8A further detailed description of the present application is provided.

[0038] An embodiment of the present application discloses a general-purpose busbar converter.

[0039] Embodiment 1

[0040] Referring to Figure 1 、 2 Figures 3 and 8, a general-purpose busbar converter includes a fixed bracket 1 made of insulating plastic. A conductive copper bar 4 is provided at the lower part of the fixed bracket 1, and system brackets 5 are provided at both ends of the conductive copper bar 4. An upper cover 2 made of the same insulating material is fixedly connected to the upper part of the fixed bracket 1 by screws. A molded case circuit breaker 12 is provided on the upper part of the upper cover 2. A number of small squares 10 are provided on the surface of the upper cover 2 away from the fixed bracket 1. A number of reserved hole supports 9 are symmetrically provided on both sides of the number of small squares 10. Different reserved bolt holes 6 are provided inside the number of reserved hole supports 9 according to different models, and the number of reserved hole supports 9 reserves different reserved bolt holes 6 according to the models of the molded case circuit breakers 12 commonly used in the market.

[0041] A protective cover 8 is clamped on one side of the upper cover 2 where the flexible copper bar 36 is located. A number of isolation spaces 13 are separated inside the protective cover 8. The space size of these number of isolation spaces 13 is just larger than the size of the flexible copper bar 36, and the number of isolation spaces 13 is the same as the number of flexible copper bars 36 to ensure that each isolation space 13 contains a flexible copper bar 36. A number of positioning grooves 11 are opened at the bottom of the fixed bracket 1, and each positioning groove 11 corresponds to a fixed seat 31 and can be movably connected to the fixed seat 31.

[0042] Through the above settings, the fixation of the fixed bracket 1 and the upper cover 2 can better fix the molded case circuit breaker 12, and the fixed bracket 1 can fix the upper cover 2 together on the conductive copper bar 4, and at the same time, it also fixes the molded case circuit breaker 12 together on the conductive copper bar 4. The system brackets 5 on both sides of the conductive copper bar 4 can provide support for the conductive copper bar 4 and can simultaneously conduct current to the conductive copper bar 4 and then to the molded case circuit breaker 12.

[0043] The small squares 10 can provide support and heat dissipation between the upper cover 2 and the fixed bracket 1. Different reserved bolt holes 6 can be reserved in advance inside the reserved hole supports 9 according to different molded case circuit breakers 12. The isolation spaces 13 separated inside the cavity of the protective cover 8 correspond one-to-one with the flexible copper bars 36, which can provide protection for the flexible copper bars 36 and enable the current to pass through the flexible copper bars 36 without mutual electromagnetic interference. The positioning grooves 11 correspond to the fixed seats 31 and can accommodate the movement of the fixed seats 31. The positioning grooves 11 can not only provide protection for the fixed seats 31 but also play a role in positioning the fixed seats 31.

[0044] Referring toFigure 4 , 5 , 6, 7. There are several connecting mechanisms 3 arranged between the fixed bracket 1 and the upper cover 2. Each connecting mechanism 3 not only has the same structure but also the same installation method. The connecting mechanism 3 includes a fixed seat 31 fixedly connected to the conductive copper bar 4. Two clamping grooves 37 are opened at the lower part of the fixed seat 31. The opening sizes of the two clamping grooves 37 are exactly the same as the height of the conductive copper bar 4, and the two clamping grooves 37 just clamp on the conductive copper bar 4. The lower surface of the inner cavity of the upper part of the fixed seat 31 abuts against the upper surface of the U-shaped bending groove 34. The middle part of the upper surface of the fixed seat 31 is exactly penetrated by the threaded end of the hexagon socket head screw 33, and the other end of the hexagon socket head screw 33 abuts against the upper surface of the U-shaped bending groove 34. One side surface of the U-shaped bending groove 34 away from the hexagon socket head screw 33 is fixedly connected to one side surface of the hard copper bar 32. The two ends of the hard copper bar 32 are provided with screw holes of the same size as the self-tapping screws 7. The lower part of the hard copper bar 32 fits with the upper part of the fixed bracket 1, and the hard copper bar 32 can be fixed on the upper part of the fixed bracket 1 through the screw holes at both ends and the self-tapping screws 7. One side surface of the hard copper bar 32 away from the U-shaped bending groove 34 is fixedly connected to the lower surface of the lower part of the flexible copper bar 36. One side of the flexible copper bar 36 away from the hard copper bar 32 is connected to the molded case circuit breaker 12. An insulating protective ring sleeve 35 is sleeved on the outer surface of the flexible copper bar 36.

[0045] Through the above settings, the hexagon socket head screw 33 is threaded through the fixed seat 31 and abuts against the fixed seat 31, and the clamping groove 37 can be clamped and fixed with the conductive copper bar 4. So when the clamping groove 37 is clamped and fixed with the conductive copper bar 4, turn the hexagon socket head screw 33 to make the hexagon socket head screw 33 push the U-shaped bending groove 34 close to the conductive copper bar 4 until it is completely fitted. Since the hexagon socket head screw 33 and the U-shaped bending groove 34 are in threaded connection, the U-shaped bending groove 34 plays a limiting role on the hexagon socket head screw 33 and the U-shaped bending groove 34 after the U-shaped bending groove 34 is pushed by the hexagon socket head screw 33. The U-shaped bending groove 34 abuts against the conductive copper bar 4, so that the current can be transmitted from the conductive copper bar 4 to the U-shaped bending groove 34 and the hard copper bar 32, and then transmitted to the flexible copper bar 36, and finally transmitted into the molded case circuit breaker 12 through the flexible copper bar 36.

[0046] It should be noted that the flexible copper bar 36 is formed by stacking multiple pieces together. The multi-layer flexible copper bar 36 can not only have good electrical conductivity but also facilitate the adjustment in the up-down and front-back directions.

[0047] The implementation principle of a general bus converter in an embodiment of this application is as follows: The fixing base 31 located in the positioning groove 11 at the bottom of the fixing bracket 1 is clamped with the conductive copper bar 4, and then the hexagon socket screw 33 is turned to make the U-shaped bending groove 34 abut against the surface of the conductive copper bar 4. In this way, the current can be transmitted through the conductive copper bar 4 to the hard copper bar 32, and then through the hard copper bar 32 to the flexible copper bar 36. Align the molded case circuit breaker 12 with the reserved bolt holes 6 reserved at the upper part of the upper cover 2, and then use screws to fix the molded case circuit breaker 12 on the upper cover 2. Then adjust the flexible copper bar 36 to align the flexible copper bar 36 with the terminal of the molded case circuit breaker 12, and then fix the flexible copper bar 36 on the terminal of the molded case circuit breaker 12 with screws. In this way, the current can be transmitted to the molded case circuit breaker 12 through the flexible copper bar 36.

[0048] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
