Description

Technical Field

[0001] This utility model relates to the technical field of DC wiring components, and in particular to a modular assembly DC parallel system wiring component. Background Technology

[0002] Modular assembly-type DC parallel system wiring components integrate conductivity, fixing, and protection functions into standardized independent modules. These components enable the parallel connection of multiple DC modules, such as power supply and energy storage modules, through assembly and combination. They simplify installation and maintenance processes, improve system flexibility and scalability, and enhance safety and operational reliability. They are widely used in energy storage systems, DC power supply networks, industrial DC equipment, and new energy equipment, and are key components for ensuring the efficient and safe parallel operation of DC systems.

[0003] DC parallel system wiring components are generally composed of conductive connectors, structural fixing components, safety protection components, etc. Through the synergy of modular structures, DC parallel system wiring components enable the parallel conduction of DC modules through initial protection limit, unlocking and exposing the connector, and docking. They also rely on protection components to ensure safety and stability, achieving convenient and reliable parallel connection of multiple DC modules.

[0004] Existing DC parallel system wiring components cannot adjust the transmission line length according to different situations, resulting in poor installation adaptability, limited application scenarios, increased line loss, reduced safety, difficulties in maintenance and expansion, resource waste and increased costs, and impact on system stability. These issues restrict the performance of DC parallel systems from multiple dimensions. Designs with transmission line length adjustment functions can effectively avoid these problems and improve system adaptability and reliability. Therefore, a modular assembly-type DC parallel system wiring component is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular assembly-type DC parallel system wiring component, which aims to improve the problem that the length of the transmission line cannot be adjusted according to different situations in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A modular, assembled DC parallel system wiring component includes a connector, with two assembly connection ports fixedly connected inside the connector, an extension mechanism fixedly connected inside the connector, a connection mechanism fixedly connected to the end of the extension mechanism away from the connector, and a fixing mechanism fixedly connected to the outer side of the extension mechanism. The extension mechanism includes a transmission line, one end of which is fixedly connected to the outside of the connector. A housing is slidably connected to the outside of the transmission line. A rotating rod is rotatably connected inside the housing. A connecting disc is slidably connected inside the rotating rod. A connecting shell is rotatably connected to the outside of the connecting disc. An extrusion assembly is fixedly connected to the outside of the housing. Furthermore, the connector achieves modular docking through the assembly connection port. The transmission line can move inside the housing. The rotating rod rotates with the transmission line. The connecting plate drives the rotating rod to retract the transmission line. The pressing component fixes the position of the transmission line. The extension mechanism achieves length adjustment and connection fixation through the above cooperation.

[0007] As a further description of the above technical solution: The extrusion assembly includes a fixed shell, the outer side of which is fixedly connected to the outer side of the outer shell. A rotating block is rotatably connected to the outer side of the fixed shell. An extrusion plate is fixedly connected to the outer side of the rotating block. A limiting shell is slidably connected to the outer side of the extrusion plate. An extrusion rod is fixedly connected to the outer side of the limiting shell. A spring is fixedly connected to the outer side of the limiting shell. Two large sliding grooves are opened inside the limiting shell. Two small slots are opened inside the limiting shell. Furthermore, when the extrusion assembly is working, rotating the rotating block on the outside of the fixed shell drives the extrusion plate to rotate. The extrusion plate pushes the limiting shell to move, so that the extrusion rod approaches and fixes the transmission line. When the limiting shell moves, it compresses the spring, generating a reverse elastic force, releasing the rotating block. The spring resets and pushes the limiting shell back, causing the extrusion rod to disengage from the transmission line and release the fixation, thus realizing flexible adjustment of the transmission line length.

[0008] As a further description of the above technical solution: The connection mechanism includes a connecting block, the outer side of which is fixedly connected to one end of the transmission line, and a plug is fixedly connected to the end of the connecting block away from the transmission line. Furthermore, in the connection mechanism, the connecting block is fixed to one end of the transmission line, and the plug at the other end is used to connect to an external interface. When the length of the transmission line is adjusted by the extension mechanism, the connecting block moves synchronously with the transmission line, causing the plug to change position. After the plug is connected to the corresponding interface, current or signal transmission is realized through the connecting block and the transmission line, adapting to connection requirements of different distances.

[0009] As a further description of the above technical solution: The outer side of the limiting shell is slidably connected to the inside of the fixed shell, and the other end of the spring is fixedly connected to the inside of the fixed shell; Furthermore, the limiting shell can slide inside the fixed shell. The two ends of the spring are connected to the limiting shell and the fixed shell respectively. When the rotating block is rotated, the extrusion plate pushes the limiting shell to slide along the fixed shell, compresses the spring to store elastic force, releases the rotating block, and the spring force pushes the limiting shell to slide back to its original position, causing the extrusion plate and the rotating block to return to their original positions, so that the extrusion rod releases the transmission line, realizing tension adjustment and fixation.

[0010] As a further description of the above technical solution: The bottom of the connecting shell is threaded to the inside of the outer shell, and the outer side of the extrusion rod is slidably connected to the inside of the fixing shell; Furthermore, the bottom of the connecting shell is threaded to the outer shell, which can fix the position of the connecting plate. The extrusion rod slides inside the fixed shell. When used with the extrusion assembly, it can accurately extrude the transmission line. Rotating the connecting shell adjusts the position of the connecting plate, and the movement of the extrusion rod fixes the transmission line, enhancing the overall connection stability and adapting to different length requirements.

[0011] As a further description of the above technical solution: One end of the extrusion rod is slidably connected to the outside of the transmission line, and the outside of the spring is slidably connected to the inside of the housing; Furthermore, one end of the compression rod slides against the outside of the transmission line. When driven, it compresses the transmission line to fix its position, and when released, it detaches to release. The spring slides inside the outer shell and extends and retracts with the movement of the limiting shell. Its elasticity assists the limiting shell in resetting and drives the compression rod to release the transmission line. The two work together to achieve the fixing and release of the transmission line, ensuring the controllability of the length adjustment.

[0012] As a further description of the above technical solution: The fixing mechanism includes a limiting shell, the outer side of which is fixedly connected to the outer side of the outer shell, and the inner side of which is threaded with bolts.

[0013] Furthermore, the transmission line inside the limiting shell is secured by rotating the bolts.

[0014] This utility model has the following beneficial effects: In this invention, the transmission line is combined with a housing and a fixed housing. The housing is combined with a rotating rod, the rotating rod with a connecting housing, the connecting housing with a connecting plate, the fixed housing with a rotating block, the rotating block with a pressing plate, and the pressing plate with a limiting housing and a pressing rod. This allows the length of the transmission line to be adjusted according to the site conditions. This invention offers advantages such as simple operation, reduced reliance on manual labor, protection of the transmission line, and extended service life. It achieves a balance between flexibility and reliability and can efficiently meet the installation and operation requirements of DC parallel systems in complex scenarios.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 3 and Figure 4 A modular, assembled DC parallel system wiring component includes a connector 1, which is the core load-bearing component of the entire wiring component. The internal structural design of the connector 1 ensures the stable assembly of each component. There are two fixed assembly connection ports 2, which can realize the quick docking between multiple connectors 1, facilitating the modular expansion and combination of the system. An extension mechanism 3 is also fixedly connected inside the connector 1. The extension mechanism 3 serves as the support and adjustment carrier for the transmission line 31, providing a structural basis for adjusting the length of the transmission line 31. A connection mechanism 4 is fixedly connected to the end of the extension mechanism 3 away from the connector 1. The connection mechanism 4 is the key part for realizing electrical connection with external equipment or other connectors 1.

[0019] The extension mechanism 3 includes a transmission line 31, one end of which is fixedly connected to the outside of the connector 1, enabling the connector 1 to conduct signals or electricity through the transmission line 31. A housing 32 is slidably connected to the outside of the transmission line 31, providing a closed space for the extension and retraction of the transmission line 31 and protecting the internal components. A rotating rod 33 is rotatably connected inside the housing 32, which can wind or unwind the transmission line 31 by rotating, thereby adjusting its length. A connecting disc 35 is slidably connected inside the rotating rod 33, which can drive the rotating rod 33 to rotate synchronously, facilitating the control of the rotation of the rotating rod 33. A connecting shell 34 is rotatably connected to the outside of the connecting disc 35, which supports and limits the connecting disc 35 to ensure its stable rotation. A pressing component 36 is fixedly connected to the outside of the housing 32, which can press the transmission line 31 to fix its position and prevent displacement during use.

[0020] Reference Figure 3 , Figure 4 The extrusion assembly 36 includes a fixed shell 361, which is a cavity for installing and protecting the internal parts. The fixed shell 361 is fixedly connected to the outside of the outer shell 32, so that the extrusion assembly 36 can stably act on the outer shell 32 and the transmission line 31. A rotating block 362 is rotatably connected to the outside of the fixed shell 361. The rotating block 362 is the input end of the operation. By rotating, it can drive other components to move together. An extrusion plate 363 is fixedly connected to the outside of the rotating block 362. The extrusion plate 363 can convert the rotational motion of the rotating block 362 into an extrusion force on the limiting shell 364. The limiting shell 364 is provided on the outside of the extrusion plate 363.

[0021] The limiting shell 364 can be displaced under the action of the extrusion plate 363, thereby driving the extrusion rod 365 to move. The outer side of the limiting shell 364 is set inside the fixed shell 361. The fixed shell 361 provides guidance for the sliding of the limiting shell 364, ensuring its accurate movement direction. The extrusion rod 365 is fixedly connected to the outer side of the limiting shell 364. The extrusion rod 365 can directly act on the transmission line 31, and the length of the transmission line 31 can be fixed and adjusted by extrusion. One end of the extrusion rod 365 is set outside the transmission line 31. This setting can not only ensure the effective extrusion of the transmission line 31 by the extrusion rod 365, but also reduce friction damage when the length of the transmission line 31 is adjusted. The outer side of the extrusion rod 365 is set inside the outer shell 32. The outer shell 32 provides stable guidance for the movement of the extrusion rod 365, ensuring accurate extrusion direction. The outer side of the limiting shell 364 is fixedly connected to the outer side. The spring 366 has an elastic reset function. When the force of the extrusion plate 363 changes, it can drive the limiting shell 364 to reset.

[0022] The outer side of the spring 366 is located inside the outer casing 32, which provides space for the extension and retraction of the spring 366, preventing its movement from being obstructed. The other end of the spring 366 is fixedly connected to the inside of the fixed casing 361. This fixing method allows the spring 366 to stably generate elastic force between the limiting casing 364 and the fixed casing 361. The other end of the spring 366 is fixedly connected to the inside of the fixed casing 361, which further enhances the stability of the spring 366 installation and ensures its reliable elastic force. The limiting casing 364 has two large sliding grooves 367 and two small slots 368 inside. The connecting mechanism 4 includes a connecting block 41, which connects the transmission line 31 and the plug 42, allowing electrical energy to be transferred from the transmission line 31 to the plug 42. Its outer side is fixedly connected to one end of the transmission line 31, ensuring the firmness of the connection. The end of the connecting block 41 away from the transmission line 31 is fixedly connected to the plug 42. The plug 42 can be inserted into the corresponding socket to realize the circuit connection. It is a key component for the connection mechanism 4 to interface with external equipment.

[0023] The fixing mechanism 5 includes a second limiting shell 51, which provides an installation base for the bolt 52 and can stably support the adjustment of the bolt 52. The outer side of the second limiting shell 51 is fixedly connected to the outer side of the outer shell 32, so that the fixing mechanism 5 and the outer shell 32 form an integral whole, ensuring the structural stability during the fixing operation. The bolt 52 is threaded inside the second limiting shell 51. Through the thread engagement, the bolt 52 can move in and out of the second limiting shell 51, thereby squeezing or loosening the transmission line 31 and achieving the effect of fixing the position of the transmission line 31.

[0024] Working principle: When using connector 1, locate the plug 42 and its corresponding socket, aligning the plug 42 precisely with the inside of the socket. Then connector 1 can be used normally. When adjusting the length of transmission line 31, the operator first needs to hold the rotating block 362 and rotate it in the desired direction. During the rotation of the rotating block 362, the connected pressing plate 363 will rotate along with it. At this time, the pressing plate 363 will gradually rotate out from the large sliding groove 367 on the limiting shell 364. In addition to the large sliding groove 367, the limiting shell 364 also has a small locking groove 368. The size and position of this small locking groove 368 match the pressing plate 363. Next, continue rotating the rotating block 362 to rotate the extrusion plate 363 to the position of the small slot 368, so that it fits perfectly with the small slot 368. After the extrusion plate 363 is inserted into the small slot 368, it will exert a compressive force on the first limiting shell 364 to one side. Under the action of this compressive force, the first limiting shell 364 will push the extrusion rod 365 to move outward of the transmission line 31. The extrusion rod 365 will press tightly against the outside of the transmission line 31. Through this compressive action, the transmission line 31 can be fixed. The other end of the transmission line 31 can be fixed by rotating the bolt 52 to the inside of the second limiting shell 51. The bolt 52 will press against the outside of the transmission line 31, thereby achieving the effect of fixing the other side of the transmission line 31.

[0025] When the length of the transmission line 31 needs to be adjusted, the transmission line 31 can be pulled to both sides simultaneously. At this time, the transmission line 31 wrapped around the outside of the rotating rod 33 will be pulled out one by one. Since the transmission line 31 passes through the inside of the rotating rod 33, the rotating rod 33 will rotate when the transmission line 31 is pulled. When the length of the transmission line 31 is pulled to the appropriate position, the components on both sides can be used to squeeze the transmission line 31, thereby fixing the length of the transmission line 31. When it is necessary to retract the excess part of the transmission line 31 into the inside of the outer casing 32, the connecting plate 35 can be rotated. The connecting plate 35 drives the rotating rod 33 to rotate, and at the same time, the transmission line 31 is pulled into the inside of the outer casing 32, thereby adjusting the length of the transmission line 31.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
