Description

Technical Field

[0001] This utility model relates to the field of power engineering equipment technology, specifically to a busbar connector. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] During the laying process, two busbar trunkings need to be connected by connectors. The connectors have two connecting parts that connect to the two adjacent busbar trunkings. In order to adapt to the shape of the building structure and other installation structures, the shape of the busbar trunking can be divided into straight type and right angle elbow type, etc., which makes the structure of the busbar trunking diverse and increases the production cost of the busbar trunking.

[0004] Furthermore, the bending angle of the busbar trunking is a fixed structure after manufacturing, and the bending angle cannot be adjusted again, which has certain limitations in use.

[0005] To address this, the inventors improved the connectors necessary for busbar duct installation, enabling the two connecting parts of the connector to change their relative angles, and the angles can be adjusted according to actual needs, allowing the busbar duct to adapt to irregular areas such as bends during installation.

[0006] In view of this, the purpose of this utility model is to provide a busbar connector to solve the problem that the bending angle of the busbar cannot be adjusted in irregular areas such as bending points during the laying process, resulting in poor adaptability.

[0007] This utility model is achieved through the following technical solution:

[0008] A busbar connector includes a first connecting portion and a second connecting portion for connecting to the ends of two adjacent busbars, a third connecting portion is provided between the first connecting portion and the second connecting portion, the first connecting portion and the second connecting portion are rotatably connected to opposite sides of the third connecting portion, and are respectively rotatable about the rotatable connection point as an axis.

[0011] Further specified, the first plate is provided with a first insulating pad on the side of the first plate facing away from the second plate, and the second plate is provided with a second insulating pad on the side of the second plate facing away from the first plate.

[0012] Further, positioning holes are provided on opposite sides of both ends of the first plate and the second plate, and positioning protrusions that can be inserted into the positioning holes are provided on both sides of the end of the first electrode plate and the second electrode plate located between the first plate and the second plate.

[0013] Further specified, the edge of the first insulating pad is provided with a first annular retaining ring that wraps around the body of the first plate, and the edge of the second insulating pad is provided with a second annular retaining ring that wraps around the body of the second plate;

[0014] The first electrode plate and the second electrode plate are both wrapped with an insulating plate on one side located between the first plate body and the second plate body. The two sides of the insulating plate are respectively sealed with the first annular retaining ring and the second annular retaining ring.

[0015] Further defined, both ends of the first electrode plate, both ends of the second electrode plate, both ends of the first plate body, and both ends of the second plate body are all circular structures, the positioning hole is located at the center of the first plate body and both ends of the plate body, and the positioning protrusion is located at the center of the first plate body and both ends of the second plate body.

[0016] Further specified, mounting holes are provided at both ends of the first plate, one of the mounting holes passing through the first plate, the first electrode plate and the second plate in sequence, and the other mounting hole passing through the first plate, the second electrode plate and the second plate in sequence;

This allows the first and second connecting parts to combine and change into a zigzag structure via the third connecting part. By changing the connection angle between the first and second connecting parts and the third connecting part, the connector adapts to the busbar's installation process.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0039] Please see Figure 1-9This utility model provides a technical solution: a busbar connector, including a first connecting part and a second connecting part for connecting to the ends of two adjacent busbars, a third connecting part is provided between the first connecting part and the second connecting part, the first connecting part and the second connecting part are rotatably connected to opposite sides of the third connecting part, and are respectively rotatable about the rotatable connection point as an axis.

[0040] The first connecting part and the second connecting part serve as connection structures between the ends of two adjacent busbar trunking sections, respectively. They are connected by a third connecting part and form a current conduction structure. The first connecting part and the second connecting part are rotatably connected to the two ends of the third connecting part, that is, the angle between the first connecting part and the second connecting part can be changed by rotation to adapt to the angle change between the two adjacent busbar trunking sections.

[0041] For example, in the initial state, the first connecting part and the second connecting part will be located at the two ends of the third connecting part, and will extend in opposite directions to the two ends of the third connecting part and be located on the same straight line.

[0042] The first connecting part and the second connecting part can rotate towards each other, that is, the first connecting part and the second connecting part can rotate to the same side of the third connecting part, so that the angle between them changes to accommodate the installation of the two busbar trunks in the bending position.

[0043] Similarly, the same effect can be achieved by rotating either the first connecting part or the second connecting part individually;

[0044] Alternatively, the first connecting part and the second connecting part rotate synchronously in the same direction, that is, the first connecting part and the second connecting part rotate synchronously in the same direction around the third connecting part respectively. In other words, the first connecting part and the second connecting part will remain on two misaligned parallel lines during the rotation. That is, the first connecting part and the second connecting part can be combined and transformed into a zigzag structure through the third connecting part.

[0045] The above technical solution allows for the adaptation of the busbar trunking during installation by changing the connection angle between the first and second connecting parts and the third connecting part.

[0046] In this embodiment, the first connecting part includes a plurality of overlapping first electrode plates 1, and the second connecting part includes a plurality of second electrode plates 2 that are arranged in a one-to-one correspondence with the plurality of first electrode plates 1. A conductive plate is disposed between the corresponding first electrode plates 1 and second electrode plates 2. One end of the first electrode plate 1 and the second electrode plate 2 are respectively rotatably connected to the two ends of the conductive plate, and the plurality of conductive plates constitute a third connecting part.

[0047] Multiple first electrode plates 1 and multiple second electrode plates 2 respectively constitute a first connecting part and a third connecting part. Multiple first electrode plates 1 and multiple second electrode plates 2 are respectively used to connect with the electrodes at the ends of two adjacent busbars. Each first electrode plate 1 and each second electrode plate 2 is independent and is connected by a conductive plate. The multiple first electrode plates 1 and multiple second electrode plates 2 and multiple conductive plates can be isolated by setting an insulating structure.

[0048] In this embodiment, the conductive plate includes a first plate 3 and a second plate 4 that are stacked together, with the ends of the first electrode plate 1 and the second electrode plate 2 respectively inserted between the two ends of the first plate 3 and the second plate 4.

[0049] The conductive plate is composed of a first plate body 3 and a second plate body 4, and the two ends of the first plate body 3 and the second plate body 4 are respectively clamped to the ends of the first electrode plate 1 and the second electrode plate 2. This can increase the cross-sectional area of ​​the conductive plate and the contact area between it and the first electrode plate 1 and the second electrode plate 2, and can reduce the resistance value to a certain extent.

[0050] In this embodiment, a first insulating pad 5 is provided on the side of the first plate 3 facing away from the second plate 4, and a second insulating pad 6 is provided on the side of the second plate 4 facing away from the first plate 3.

[0051] By setting the first insulating pad 5 and the second insulating pad 6, the first plate 3 and the second plate 4 are clamped and wrapped, so that the two are in an independent state. That is, the first electrode plate 1 and the second electrode plate 2 that cooperate with the first plate 3 and the second plate 4 will also be in an independent state, and can be in an independent state during the overlapping installation process.

[0052] In this embodiment, positioning holes 7 are provided on opposite sides of both ends of the first plate 3 and the second plate 4, and positioning protrusions 8 that can be inserted into the positioning holes 7 are provided on both sides of the first electrode plate 1 and the second electrode plate 2 located between the first plate 3 and the second plate 4.

[0053] The positioning hole 7 and the positioning protrusion 8 are interlocked and serve as rotational connection fulcrums between the first electrode plate 1 and the second electrode plate 2 and the first plate body 3 and the second plate body 4, which can improve the stability of the overall structure.

[0054] In this embodiment, the edge of the first insulating pad 5 is provided with a first annular retaining ring 9 that wraps around the first plate 3, and the edge of the second insulating pad 6 is provided with a second annular retaining ring 10 that wraps around the second plate 4.

[0055] The first electrode plate 1 and the second electrode plate 2 are both wrapped with an insulating plate 13 on one side between the first plate body 3 and the second plate body 4. The two sides of the insulating plate 13 are respectively sealed with the first annular retaining ring 9 and the second annular retaining ring 10.

[0056] The first annular retaining ring 9 and the second annular retaining ring 10 serve as structural extensions of the first insulating pad 5 and the second insulating pad 6, respectively, and wrap the first plate 3 and the second plate 4 to provide insulation and isolation from the outside, thereby further improving the insulation and protection effect. In addition, by setting an insulating plate 13 to wrap the side of the first electrode plate 1 and the second electrode plate 2 located between the first plate 3 and the second plate 4, the end can be in an insulating state when it deviates from the first plate 3 and the second plate 4 during rotation.

[0057] In this embodiment, both ends of the first electrode plate 1, both ends of the second electrode plate 2, both ends of the first plate body 3, and both ends of the second plate body 4 are circular structures. The positioning hole 7 is located at the center of the first plate body 3 and both ends of the plate body, and the positioning protrusion 8 is located at the center of the first plate body 3 and both ends of the second plate body 4.

[0058] That is, the first electrode plate 1 and the second electrode plate 2 can maintain a fixed contact area with the first plate body 3 and the second plate body 4 during the rotation process.

[0059] In this embodiment, mounting holes are provided at both ends of the first plate 3. One of the mounting holes passes through the first plate 3, the first electrode plate 1, and the second plate 4 in sequence, and the other mounting hole passes through the first plate 3, the second electrode plate 2, and the second plate 4 in sequence.

[0060] Furthermore, the two mounting holes respectively penetrate the two positioning protrusions 8;

[0061] A fastening bolt 11 is inserted into the mounting hole, and an insulating sleeve 12 is provided over the fastening bolt 11.

[0062] The fastening bolt 11 passes through the mounting hole, and by using the matching nut, multiple assemblies consisting of the first electrode plate 1, the second electrode plate 2, the conductive plate, the first insulating pad 5 and the second insulating pad 6 can be fastened as a whole, or the assembly can be loosened by rotating the nut to adjust the angle. The operation is simple.

[0063] Meanwhile, by installing an insulating sleeve 12 over the fastening bolt 11, the fastening bolt 11 and multiple assemblies can be isolated from each other, achieving the effect of mutual insulation.

[0064] In this embodiment, the outer side of the insulating plate 13 is an arc centered on the center of the positioning protrusion 8. A pad 14 is provided between the two insulating plates 13. The pad 14 has two arc-shaped grooves 15 corresponding to the two insulating plates 13. The two insulating plates 13 are respectively located in the two arc-shaped grooves 15.

[0065] The outer side of the insulating plate 13 is arc-shaped and centered with the center of the positioning protrusion 8. It can fit into the circular end edge of the first electrode plate 1 and the second electrode plate 2. The pad block 14 has an arc-shaped groove 15 that cooperates with the insulating plate 13, which serves as a rotation support so that the two insulating plates 13 are pressed against each other and maintain a close fit with the first electrode plate 1 and the second electrode plate 2 during rotation.

[0066] In this embodiment, the contact surfaces between the first electrode plate 1 and the second electrode plate 2 and the first plate body 3 and the second plate body 4, as well as the contact surfaces between the first plate body 3 and the second plate body 4 and the first electrode plate 1 and the second electrode plate 2, are all smooth planes.

[0067] A smooth surface can effectively improve the contact effect between the first electrode plate 1, the second electrode plate 2 and the first plate body 3 and the second plate body 4, improve the conductivity, and reduce friction, thereby reducing the frictional loss of the first electrode plate 1 and the second electrode plate 2 during rotation.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
