Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a bus connection structure for a distribution cabinet. Background Art

[0002] In the power system, the bus connects each current-carrying branch circuit in the distribution device, playing the role of collecting, distributing, and transmitting electric energy. Most of the existing connection structures of bus ducts adopt a connection groove structure. The connection plates of two bus ducts are clamped into the inside of this connection groove, and then bolts and nuts are used to pass through the connection ports of the bus duct connection plates to fix them. This method requires a special connection mechanism. For example, in the prior art: CN218386679U, a connection structure for a low-voltage distribution cabinet bus duct, includes a connection seat. A limit groove is opened at the bottom of the inner surface of the connection seat. An adjusting mechanism is movably connected inside the limit groove. An insulating block is fixedly connected to the top of the adjusting mechanism. Conductive blocks are fixedly connected to both sides of the insulating block. A conducting wire is fixedly connected inside the conductive block.

[0003] There is also prior art:

[0004] CN215600982U, a connection structure for a low-voltage distribution cabinet bus duct;

[0005] CN212366464U, a distribution cabinet convenient for bus connection and wire routing.

[0006] Although the above prior art increases the wire ducts to achieve the integration of multiple lines, the unified integration method makes it impossible to uniformly fix lines of different thicknesses, and lines with different thicknesses and functions cannot be distinguished. Moreover, due to the dense lines, heat generated during high-power operation cannot be discharged. The accumulated heat is too high, which may cause a short circuit, and a heat dissipation device needs to be added on this basis. Content of the Utility Model

[0007] The purpose of the utility model is to provide a bus connection structure for a distribution cabinet to solve the problems raised in the above background art.

[0008] To achieve the above object, the present utility model provides the following technical solution: a bus connection structure for a distribution cabinet, including a connection seat and an adjustment plate, characterized in that: the adjustment plates are uniformly arranged longitudinally inside the connection seat, a movable cavity is transversely opened at the bottom of the connection seat, a threaded rod is installed through the movable cavity, both ends of the threaded rod are arranged on the side walls of the connection seat, a movable block is fixedly connected to the bottom of the adjustment plate, the movable block is inlaid and installed in the movable cavity, a threaded hole is opened at the center of the movable block, and the threaded rod passes through the threaded hole and is in threaded engagement at two places. A limiting block is arranged near the top of the inner wall of the connection seat, limiting blocks are arranged near the top on both the left and right sides of the movable block, and a heat dissipation plate is arranged on the top of the movable block.

[0009] Preferably, the limiting block and the heat dissipation plate are made of metal, the side surface of the limiting block is arc-shaped, and the limiting block and the heat dissipation plate are connected together.

[0010] Preferably, the connection seat and the adjustment plate are made of insulating materials or are subjected to insulating treatment on the surface.

[0011] Preferably, an internal hexagonal head is fixedly connected to the right side of the threaded rod.

[0012] Preferably, a fastening screw is arranged at the center position of the bottom plate of the connection seat.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For this bus connection structure of the distribution cabinet, by rotating the threaded rod, the movable block and the adjustment plate are driven to move left and right, and the distance between the adjustment plates is adjusted, so that the adjustment plates can clamp various lines with different thicknesses. At the same time, by rotating multiple threaded rods, each threaded rod corresponds to a different movable block and adjusting rod, so as to adjust the distance between each adjustment plate to clamp lines with different thicknesses simultaneously.

[0015] 2. For this bus connection structure of the distribution cabinet, the limiting block absorbs the heat transmitted from the line and transfers the heat to the heat dissipation plate again. Through the large heat dissipation area of the heat dissipation plate, the heat generated by the line transmission is reduced, and the possibility of short circuit or even fire caused by the overhigh temperature of the device is reduced.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment: Please refer to Figure 1 , the present invention provides a technical solution: a bus connection structure for a power distribution cabinet.

[0023] Among them, the adjusting plates 2 are uniformly arranged longitudinally inside the connection seat 1. A movable cavity 5 is transversely opened at the bottom of the connection seat 1. A threaded rod 4 is installed through the movable cavity 5. Both ends of the threaded rod 4 are arranged on the side walls of the connection seat 1. The bottom of the adjusting plate 2 is fixedly connected with a movable block 3. The movable block 3 is embedded in the movable cavity 5. A threaded hole is opened in the center of the movable block 3. The threaded rod 4 passes through the threaded hole and is threadedly engaged at two places. A limiting block 6 is arranged near the top of the inner wall of the connection seat 1. Limiting blocks 6 are arranged near the top on the left and right sides of the movable block 3. A heat dissipation plate 7 is arranged on the top of the movable block 3.

[0024] In this embodiment, the connection seat 1 is divided into front and rear parts, and the positions and sizes of the front and rear parts are completely symmetrical. The length, width of the connection seat 1 and the number of adjusting plates 2 can be changed according to the needs of the user. Among them, the number of movable cavities 5 is the same as the number of adjusting plates 2, and the number of threaded rods 4 arranged in the movable cavities 5 is also the same. The length and width of the movable block 3 are the same as those of the movable cavity 5, so that the movable block 3 can be embedded in the movable cavity 5. The movable block 3 is connected to the threaded rod 4 through the thread in the center. The positions of the movable blocks 3 at the bottom of each adjusting plate 2 are different. The movable blocks 3 correspond to the movable cavities 5 from front to back in sequence from right to left. Each movable block 3 can be installed in the corresponding movable cavity 5, and at the same time, the adjusting plates 2 above are made flush. Rotate the threaded rod 4. Since the movable block 3 cannot rotate, it moves forward or backward in the movable cavity 5 through the thread, driving the adjusting plate 2 above, thereby adjusting the distance between each adjusting plate 2, and clamping the circuit through the limiting block 6.

[0025] Among them, the limiting block 6 and the heat dissipation plate 7 are made of metal. The side surface of the limiting block 6 is arc-shaped, and the limiting block 6 and the heat dissipation plate 7 are connected together.

[0026] In this embodiment, the arc-shaped side surface can increase the contact area with the circuit, making it more convenient to clamp the circuit. This can avoid damaging the circuit when clamping with excessive force when the contact surface is small. At the same time, heat is inevitably generated during power transmission. This heat is transferred to the limit block 6 through heat transfer. The limit block 6 made of metal can conduct heat better and transfer the heat to the connected heat dissipation plate 7. The large heat dissipation area of the heat dissipation plate 7 can dissipate heat quickly. If necessary, a heat dissipation fan can be set in the power distribution cabinet to align with the heat dissipation plate, which can achieve a better heat dissipation effect.

[0027] Among them, the connecting seat 1 and the adjusting plate 2 are made of insulating materials or have their surfaces insulated.

[0028] In this embodiment, to prevent the circuit from being broken and leaking electricity, insulation treatment needs to be done at some positions of the entire device to avoid current being exported from the device and damaging other electrical components.

[0029] Among them, the right side of the threaded rod 4 is fixedly connected with an internal hexagonal head.

[0030] In this embodiment, the operator rotates the threaded rod 4 through an internal hexagonal wrench, which is more labor-saving and convenient to operate.

[0031] Among them, a fastening screw is arranged at the center of the bottom plate of the connecting seat 1.

[0032] In this embodiment, the fastening screw is used to install the device inside the power distribution cabinet and fix it to the side wall of the power distribution cabinet.

[0033] Working principle: The device is fixed in the power distribution cabinet through the fastening screw 8. Rotate the threaded rod 4 at the frontmost position to adjust the positions of the adjusting plate 2 on the rightmost side of the device and the right side wall of the connecting seat 1. Pass the circuit through the limit block on the corresponding adjusting plate 2 and clamp it with the threaded rod 4. Similarly, fix the rear adjusting plate 2. When it is necessary to clamp the second circuit, just rotate the second threaded rod 4 from front to back to drive the second adjusting plate 2 from right to left to clamp the circuit, and so on. If necessary, the width of the connecting seat 1 and the number of adjusting plates 2 can be increased, and the number of movable cavities 5 can be correspondingly increased to clamp more circuits. The heat generated during the power transmission of the circuit is transferred to the heat dissipation plate 7 through the limit block 6, and the heat is dissipated through the heat dissipation plate 7 to reduce the temperature of the circuit and ensure the transmission stability.

[0034] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
