[0001] This utility model relates to the field of electrical busbar system technology, and in particular to a dense busbar connector and cast busbar. Background Technology

[0002] Cast iron busbars, as electrical conduction equipment widely used in high-voltage and low-voltage power transmission systems, have seen widespread application of their air-type connectors due to their simple structure and low manufacturing cost. However, air-type connectors, as shown in the attached... Figure 1 and 2 As shown, traditional cast iron busbars suffer from problems such as easy oxidation of the contact surface, insufficient insulation performance, and large space occupation. These issues can lead to poor electrical contact, increased energy consumption, and safety hazards during long-term operation of the electrical system. Therefore, improving the plug-in interface design of traditional cast iron busbars to enhance the overall system performance has become an urgent problem to be solved.

[0003] In contrast, compact busbar connectors, through their tightly packed conductors and enhanced insulation, not only improve contact reliability and electrical performance but also effectively reduce system footprint. However, traditional cast iron busbars have not fully considered the application of compact connectors in their design and manufacturing. Therefore, this innovative redesign, which optimizes the air-type connector into a compact busbar connector form, has significant technical and application value. Utility Model Content

[0032] In order to make the above objectives, characteristics and advantages of the present application more apparent, concrete embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0033] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other manners different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0034] Secondly, the "one embodiment" or "embodiment" referred to herein means that specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0035] Embodiment 1, with reference to Figures 1 to 6 For the first embodiment of the present application, the embodiment provides a dense bus plug-in interface, which comprises a cast conductor 100, which comprises a parallel part 101, N conductors of the parallel part 101 are tightened as a dense part 102 at a non-edge position, wherein N is a natural number greater than or equal to 1;

[0036] The plug-in unit 200 comprises N plug-in interfaces 201, each plug-in interface 201 corresponds to each conductor of the dense part 102 one by one.

[0037] The N conductors of the dense part 102 are parallel to each other, and the conductor gaps of adjacent dense parts 102 are equal.

[0038] In order to be compatible with the plug-in box and the plug-in interface 201, the N conductors of the parallel part 101 are tightened as the dense part 102 at the non-edge position, which looks like "bundling" or "hooping".

[0039] The dense part 102 of the cast conductor 100 adopts densely arranged copper or aluminum conductors, and the original air type plug-in interface is designed to be a multi-contact point parallel arrangement structure. This design can increase the conductive area, reduce the contact resistance, and significantly improve the electrical performance without increasing the volume.

[0040] In addition, the design of the dense part 102 can significantly increase the utilization rate of the internal space.

[0041] The dense busbar socket is formed by high-strength epoxy resin casting, covering the whole conductive area of the socket. The epoxy resin material has excellent insulation performance, which can effectively prevent the exposure of the conductor and avoid the risk of oxidation and short circuit. The insulation layer also enhances the voltage resistance level of the socket and improves the safety of the whole system.

[0042] Embodiment 2, refer to Figure 3 and Figure 6 , which is different from the previous embodiment is that the length edges of the socket 201 are located on different straight lines, and the conductor positions corresponding to adjacent sockets 201 are adjacent or not adjacent.

[0043] Here, the conductor positions corresponding to adjacent sockets 201 are adjacent or not adjacent, which reflects the flexibility of the socket design, that is, as long as the complete coverage of the width edge and the length edge is ensured, the combination of the internal segments has no strict limitation, which can be sequential limitation, similar to step design or smooth V-shaped design, or can be segmented in a leapfrog manner.

[0044] However, regardless of which one, it is different from the traditional air-type socket, that is, multiple sockets are arranged in the same axial or radial direction, because if multiple sockets are arranged in the same radial direction, gaps between the sockets themselves also need to be reserved, plus the gaps between the conductors, which cannot fully utilize the internal space and cannot increase the conductive area.

[0045] And the segmented dense socket, that is, no gap is reserved for the sockets in the axial or radial direction, can save the internal conductor space.

[0046] Embodiment 3, refer to Figure 3 and Figure 6 , which is different from the second embodiment is that: the width edge direction of the socket 201 is parallel to the width edge of the conductor, and the width of the socket 201 is greater than the width of the conductor corresponding to the dense part 102, the projection line segment of the width edge of the socket 201 is located on the same straight line, and there is no gap between adjacent projection line segments.

[0047] Because there is a gap between the conductors of adjacent dense parts 102, the width edge of the socket 201 needs to be greater than the width of the conductor corresponding to the dense part 102.

[0048] Moreover, in order to ensure sufficient contact between the socket and the conductor, and each conductor can be contacted, the socket and the conductor are designed to correspond in the overall width direction and diverge, further optimizing the use space.

[0049] In order to ensure that the width edge is not missed, the projection line segment of the width edge of the socket 201 is located on the same straight line, and there is no gap between adjacent projection line segments.

[0050] Embodiment 4, refer to Figure 3 and Figure 6 , the fourth embodiment of the utility model, it is different from the third embodiment is: the length edge direction of the plug-in interface 201 is parallel with the axial direction of the conductor, the projection line segment formed by the length edge of the plug-in interface 201 is located on the same straight line, and there is no gap between adjacent projection line segments.

[0051] Similar to the width edge, the length edge of the plug-in interface is also designed in sections, and in order to ensure that the length edge is not missed, the projection line segment of the length edge of the plug-in interface 201 is located on the same straight line, and there is no gap between adjacent projection line segments.

[0052] Embodiment 5, refer to Figures 7-11 , the fifth embodiment of the utility model, it is different from the first four embodiments is that this embodiment provides a pouring busbar, including the dense busbar plug-in interface described above, still includes the body unit 300, including the body section 301, the non-edge position of the body section 301 is connected with the plug-in section 302, and the parallel part 101 and the dense part 102 are located in the body section 301 and the plug-in section 302 respectively.

[0053] The cross-sectional area of the body section 301 is greater than the cross-sectional area of the plug-in section 302.

[0054] In order to reserve enough pouring space, the internal space of the plug-in section 302 where the dense part 102 is located is greater than the internal space of the body section 301 where the parallel part 101 is located, so the cross-sectional area of the body section 301 is greater than the cross-sectional area of the plug-in section 302.

[0055] For the connection structure of the busbar, the dense plug-in interface adopts modular design, the installation mode of the plug-in interface is more convenient, and the need for external protection device at the connection is reduced, and the construction and maintenance process is simplified. Under the premise of ensuring the structural strength, the dense design reduces the occupied space and improves the flexibility of installation.

[0056] Embodiment 6, refer to Figures 8 to 11 , the sixth embodiment of the utility model, it is different from the first five embodiments is that this embodiment provides a plug-in section, and the plug-in section 302 includes a plug-in box 302a, N plug-in interfaces 201 are formed on the plug-in box 302a, and the pouring conductor 100 is connected with the external connecting conductor 303 through the plug-in interface 201.

[0057] The side of the plug-in box 302a close to the plug-in interface 201 is clamped with the protective cover 302b.

[0058] The conventional air type plug-in interface needs to consider dustproof, waterproof and protection measures. The plug-in module adopted in this patent has a protective cover designed on itself, which solves the problem of dustproof and waterproof.

[0059] Embodiment 7, with reference to Figures 8 to 11 The seventh embodiment of the utility model differs from the first six embodiments in that it is a socket base.

[0060] The socket box 302a is arranged on the socket base 302c; the height of the socket base 302c is equal to the height of the body section 301, and the maximum width of the socket base 302c is greater than the width of the body section 301; a drainage groove 302d is arranged between the socket box 302a and the socket base 302c, and the drainage groove 302d is in communication with the plug-in interface 201.

[0061] The pouring mode of the socket busbar is optimized, so that it is integrally formed with the socket base, dust and water vapor are prevented from entering, the sealing performance is more stringent, and the safety is greatly improved.

[0062] The construction site is complex, and many are installed in the shaft; if water flows down along the busbar, a drainage groove needs to be arranged at the socket.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and are not limited. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the utility model, and they should be covered in the scope of the claims of the utility model.
