[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference as follows Figures 1-6 The utility model is described as follows:

[0028] Example: A busbar connection structure with high power connection capacity includes a mounting base 1 made of plastic (plastic has excellent insulation properties, effectively preventing current leakage and short circuits, thereby improving busbar safety). The mounting base 1 is elongated, with three lower busbars 2 disposed on its underside. Lower mounting grooves 20 for receiving the lower busbars 2 are also provided on the underside of the mounting base 1. The lower mounting grooves 20 extend along the length of the mounting base 1. This design ensures stable installation and fixation of the lower busbars 2 on the mounting base 1 and ensures the continuity of the lower busbars 2 along the length, thereby improving the busbar's power connection capacity. The three lower mounting grooves 20 are arranged side by side across the width of the mounting base 1. This layout enables the busbar to connect to multiple electrical devices simultaneously, enhancing its versatility and flexibility. For example, different electrical devices can be connected to different lower busbars 2, enabling independent control and management of the electrical devices.

[0029] An upper busbar 3 is located on the upper side of the mounting base 1. An upper mounting groove 21 for receiving the upper busbar 3 is also provided on the upper side of the mounting base 1. Upper mounting groove 21 runs the length of the mounting base 1 and corresponds to the lower busbar 2 located in the middle. This corresponding arrangement also makes the busbar structure more compact and reduces space. Upper busbar 3, installed in upper mounting groove 21, cooperates with lower busbar 2 to achieve the transmission and distribution of electrical energy.

[0030] The lower busbar 2 is mainly used to receive and transmit electrical energy, distributing the electrical energy from the power source to various electrical devices. The lower busbar 2 is usually made of a metal material with good electrical conductivity, such as copper or aluminum, to ensure efficient transmission of electrical energy.

[0031] The upper busbar 3 is mainly used to receive and transmit electrical energy, and realizes the transmission and distribution of electrical energy together with the lower busbar 2. The upper busbar 3 is usually made of a metal material with good electrical conductivity, such as copper or aluminum, to ensure efficient transmission of electrical energy.

[0032] A connector body 4 is provided at one end of the mounting base 1. This connector body 4 is made of the same plastic material as the mounting base 1, ensuring good insulation performance. The connector body 4 is wider than the mounting base 1, providing more space for internal connecting components.

[0033] The upper busbar 3 and the lower busbar 2 extend into the connection base 4. The connection base 4 is provided with a first connection terminal 5 corresponding to the lower busbar 2. One end of the first connection terminal 5 is connected to the lower busbar 2, and the other end of the first connection terminal 5 extends out of the connection base 4. The first connection terminal 5 serves as the power connection end of the lower busbar 2.

[0034] The setting of this position makes the busbar easy to connect with other electrical equipment. The connecting seat 4, as the connecting part of the busbar, plays the role of a bridge, connecting the upper busbar 3 and the lower busbar 2 to the external circuit.

[0035] The connector body 4 is provided with first connection terminals 5 that connect to the lower bus bars 2. The number of first connection terminals 5 is the same as the number of lower bus bars 2, and each first connection terminal 5 is connected to a corresponding lower bus bar 2. This corresponding connection ensures accurate transmission of electrical energy and avoids circuit confusion and incorrect connections.

[0036] It also includes a U-shaped adapter 6, the opening of which is arranged toward the lower bus bar 2. The middle portion of the adapter 6 is electrically connected to the upper bus bar 3 and is fixedly connected by screws. This connection method is simple and reliable, and can ensure good electrical conductivity between the adapter 6 and the upper bus bar 3. Electrical connection pins 7 extend from both ends of the adapter 6, and these electrical connection pins 7 provide additional electrical connection locations for the upper bus bar 3. The length and shape of the electrical connection pins 7 can be designed according to actual needs to meet different connection requirements. One of the electrical connection pins 7 is connected to a second connection terminal 8, which can serve as one electrical connection end of the upper bus bar 3, and the other electrical connection pin 7 is connected to a connection bar 9, which can serve as the other electrical connection end of the upper bus bar 3. The second connection terminal 8 and the connection bar 9 serve as the two electrical connection ends of the upper bus bar 3, respectively, thereby enhancing the electrical connection capacity of the upper bus bar 3.

[0037] The second connection terminal 8 and the connection bar 9 transform the upper busbar 3 from a single connection point into two. This increased number of connection points effectively increases the upper busbar 3's connection capacity, meeting the connection needs of a wider range of electrical devices. Multiple connection points can simultaneously connect to multiple external circuits, enabling the distribution and transmission of electrical energy. The two connection points also enhance the connection flexibility of the upper busbar 3. Different connection methods and connectors can be selected based on actual needs to accommodate diverse installation environments and electrical requirements.

[0038] The U-shaped adapter 6, connected to the upper busbar 3, provides two additional connection points for the upper busbar 3. The second connection terminal 8 and the connection bar 9 serve as the two connection ends of the upper busbar 3, enhancing the upper busbar's connection capacity and connection flexibility. This design allows the busbar to better meet the connection requirements of different electrical devices, improving the reliability and safety of the electrical system.

[0039] The mounting base 1 and the connecting base 4 are made of the same plastic material as the mounting base 1 and the connecting base 4, ensuring good insulation performance. The long strip design allows it to fit tightly with the power strip 9, providing stable support and fixation for the power strip 9.

[0040] The fixing bar 10 is arranged corresponding to the power connection bar 9, and the power connection bar 9 extends into the fixing bar 10 and is fixedly connected to the fixing bar 10 (fixed connection by screws). This connection method is firm and reliable, and can ensure that the position of the power connection bar 9 in the fixing bar 10 is stable and will not easily loosen or fall off.

[0041] The fixing bar 10 is fixedly connected with a power connection piece 11 (fixedly connected by screws). The arrangement of the power connection piece 11 provides more power connection positions for the busbar, thereby enhancing the power connection capacity.

[0042] The device also includes a bridge bar 12 that connects the terminal strip 9 and the terminal plate 11. Terminal screws 13 are connected to the terminal plate 11 and the terminal strip 9. The two ends of the bridge bar 12 are connected to the terminal plate 11 and the terminal strip 9 respectively via the terminal screws 13. This connection method creates a good electrical connection between the terminal strip 9 and the terminal plate 11, ensuring smooth transmission of electrical energy. The use of terminal screws 13 facilitates the installation and removal of the bridge bar 12, while also providing reliable connection force and ensuring connection stability.

[0043] Through the fixing bar 10 and the bridging bar 12, the connecting piece 11, and the connecting screws 13 arranged thereon, the busbar forms more connecting positions. These connecting positions can connect to multiple external circuits at the same time to achieve the distribution and transmission of electrical energy. More connecting positions mean that the connection needs of more electrical equipment can be met, which improves the versatility and flexibility of the busbar. The setting of the fixing bar 10 and the bridging bar 12, the connecting piece 11, the connecting screws 13 and other components thereon provides the busbar with more connecting positions and enhances the connecting capacity. This design enables the busbar to better adapt to the needs of different electrical systems and improves the connection convenience and reliability of electrical equipment. At the same time, the plastic fixing bar 10 and the screw connection method also ensure the insulation performance of the busbar and the convenience of installation and maintenance.

[0044] Connector body 4 has slots 14 on either side of its width, corresponding to contact pins 7. Connector pins 15 are connected to slots 14. One end of connector pin 15 is electrically connected to contact pin 7, while the other end of connector pin 15 extends out of connector body 4. Connector pin 15 also includes a long, strip-shaped terminal block 16 connected to the other end of connector pin 15. Terminal block 16 has multiple connection points, enhancing its connection capacity.

[0045] The slotted hole 14 provides a space for installing and connecting the transfer pin 15. By inserting the transfer pin 15 into the slotted hole 14, the transfer pin 15 can be connected to the power pin 7 inside the connection base 4, thereby transmitting electrical energy from the busbar to the external circuit.

[0046] The adapter pin 15 is usually made of a metal material with good electrical conductivity, such as copper or aluminum. One end of it is electrically connected to the power pin 7, and the other end extends out of the connecting seat 4 so as to be connected to the external terminal 16. The terminal 16 is in the shape of a long strip, and this design allows it to provide multiple power connection positions. Several power connection positions on the terminal 16 can be connected to multiple external circuits at the same time to achieve the distribution and transmission of electrical energy. This design of multiple power connection positions greatly enhances the power connection capacity of the bus and meets the connection needs of more electrical equipment. The power pin 7 is connected to the terminal 16 through the adapter pin 15 to form a more complex electrical connection network. This network can connect multiple external circuits at the same time to achieve efficient distribution and transmission of electrical energy.

[0047] The slotted holes 14, adapter pins 15, and elongated terminals 16 on the connector body 4 work together to enhance the busbar's electrical connection capabilities. The slotted holes 14 provide space for the adapter pins 15 to be installed and connected. The adapter pins 15 establish an electrical connection between the connection pins 7 and the terminals 16, while the multiple connection locations on the terminals 16 provide more connection options. This design allows the busbar to better adapt to the needs of various electrical systems, improving the connection convenience and reliability of electrical equipment.

[0048] An insulating isolation block 17 is provided between the adapter 6 and the lower bus bar 2. The provision of the insulating isolation block 17 can prevent creepage between the adapter 6 and the lower bus bar 2, thereby improving the safety of the busbar.

[0049] Several power terminals 18 are provided on either side of the mounting base 1 in the width direction. These terminals 18 are arranged along the length of the mounting base 1 and are electrically connected to the upper busbar 3 or one of the lower busbars 2. These terminals 18 are used to connect to electrical equipment such as circuit breakers. These terminals 18 are provided on either side of the mounting base 1 in the width direction. This layout design allows for a more rational spatial distribution of the terminals 18, facilitating connection to electrical equipment in different orientations. Furthermore, the dual-side arrangement increases the flexibility and scalability of power connections.

[0050] Power terminal 18 is electrically connected to upper busbar 3 or one of lower busbars 2. This connection allows power terminal 18 to capture electrical energy and transmit it to the connected electrical device. The specific busbar to which it is connected can be selected based on actual needs to meet the voltage and current requirements of different electrical devices.

[0051] Covers 19 are provided on the upper sides of the mounting base 1 and the connecting base 4. These covers primarily protect the internal busbars, connecting terminals, and other components. They prevent the ingress of dust, moisture, and debris that could damage the electrical connections, thereby ensuring the proper operation and service life of the busbars.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
