Technical Field
[0001] This utility model relates to the field of flexible DC connector technology, specifically a waterproof structure for a flexible DC connector. Background Technology
[0002] Flexible DC connectors are key components in flexible DC transmission systems used to achieve high-voltage DC power transmission and equipment connection. Their main function is to connect converter stations, DC cables, substation equipment, and other power components, ensuring stable conductivity and mechanical fixation under high voltage and high current conditions. Their core role is to adapt to the "flexible control" characteristics of flexible DC transmission technology, supporting bidirectional power flow, rapid power regulation, and dynamic system response. They are important basic components for building smart grids and large-scale clean energy transmission networks.
[0003] In related technologies, the flexible DC connectors widely used in the market generally adopt a plug-in connection method during their use. Specifically, this plug-in method requires mating at specific locations. However, due to design or manufacturing limitations, these plug-in locations inevitably have certain gaps. Although these gaps seem small, they provide channels for water stains and dust from the external environment to enter. Once water stains and dust from the outside enter the connector through these gaps, they will adversely affect the internal structure and electrical performance of the connector, thereby significantly reducing the stability and reliability of the connection, and may even lead to equipment failure or damage, making it inconvenient for users to use.
[0004] Therefore, it is necessary to provide a waterproof structure for a flexible DC connector to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to provide a waterproof structure for a flexible DC connector, which solves the problem that current flexible DC connectors use a plug-in method, and the plug-in position has certain gaps, allowing external water stains and dust to enter through the gaps and affecting the stability of the connection.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for a flexible DC connector, comprising a flexible DC connector and a connector base located on the right side of the flexible DC connector, wherein a mating groove is fixedly connected to the left side of the connector base, a waterproof ring is fixedly connected to the surface of the flexible DC connector, a fixing structure is provided on the surface of the flexible DC connector, and a mating structure is provided on the surface of the connector base. The fixing structure is used to provide fixed support between the flexible DC connector and the connector base; The mating structure is used to fit and fix the fixed structure.
[0007] Preferably, the fixing component includes a fixing sleeve, which is fixedly connected to the surface of the flexible DC connector. The fixing sleeve is rotatably connected to a locking rod, and a locking block is fixedly connected to the inner side of the locking rod. A limiting plate is fixedly connected to the left side of the surface of the flexible DC connector, and a sliding rod is fixedly connected to the right side of the limiting plate. A metal ring is sleeved on the surface of the flexible DC connector, and the metal ring is slidably connected to the locking rod. A spring is sleeved on the surface of the sliding rod.
[0008] Preferably, the mating structure includes a limiting ring, which is fixedly connected to the surface of the connector base. The surface of the limiting ring has a slot, which engages with the locking rod.
[0009] Preferably, there are several sliding rods, which are evenly distributed in a ring.
[0010] Preferably, the number of waterproof rings is three, and each waterproof ring is slidably connected to the insertion groove.
[0011] Preferably, there are several clamps, which are evenly distributed in a ring.
[0012] Preferably, one end of the spring is fixedly connected to the surface of the limiting plate, and the other end of the spring is fixedly connected to the surface of a metal ring.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention addresses the issue of sealing a flexible DC connector during insertion. First, the flexible DC connector is inserted into the left side of the connector base. Then, the user places a waterproof ring inside the insertion slot, providing a seal. Next, the metal ring slides to the right, pressing it against the locking rod. This locks the locking rod and the locking block into the slot, ensuring stability between the connector base and the flexible DC connector. The resulting seal provides excellent waterproofing and achieves highly efficient waterproofing. Attached Figure Description

[0016] 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.
[0017] Please see Figure 1-5 A waterproof structure for a flexible DC connector includes a flexible DC connector 1 and a connector base 2 located on the right side of the flexible DC connector 1. A mating groove 3 is fixedly connected to the left side of the connector base 2. A waterproof ring 4 is fixedly connected to the surface of the flexible DC connector 1. A fixing structure 5 is provided on the surface of the flexible DC connector 1. A mating structure 6 is provided on the surface of the connector base 2. The fixing structure 5 is used to fix and support the flexible DC connector 1 and the connector base 2; The mating structure 6 is used to mate and fix the fixed structure 5.
[0018] Please see Figure 4 The fixing component includes a fixing sleeve 51, which is fixedly connected to the surface of the flexible DC connector 1. A locking rod 52 is rotatably connected to the fixing sleeve 51. A locking block 53 is fixedly connected to the inner side of the locking rod 52. A limiting plate 54 is fixedly connected to the left side of the surface of the flexible DC connector 1. A sliding rod 55 is fixedly connected to the right side of the limiting plate 54. A metal ring 56 is sleeved on the surface of the flexible DC connector 1. The metal ring 56 is slidably connected to the locking rod 52. A spring 57 is sleeved on the surface of the sliding rod 55.
[0019] Furthermore, by setting up the fixing components, we can effectively stabilize the connection between the flexible DC connector 1 and the connector base 2, thereby ensuring that the connection between the flexible DC connector 1 and the connector base 2 has a high degree of stability. This stability can effectively prevent the flexible DC connector 1 from shaking during use, providing users with a stable and reliable operating environment, greatly improving the user experience, and making operation more convenient and comfortable.
[0020] Please see Figure 5The cooperating structure 6 includes a limiting ring 61, which is fixedly connected to the surface of the connector base 2. The surface of the limiting ring 61 is provided with a slot 62, which engages with the locking rod 52.
[0021] Furthermore, by coordinating with the structure 6, we can precisely fix each of the card blocks 53. This fixing method can also ensure the stability between the flexible DC connector 1 and the connector base 2. This design not only simplifies the user's operation steps, but also further improves the overall structural stability, ensuring that there will be no loosening or shaking during use, thus bringing users a smoother and more efficient user experience.
[0022] Please see Figure 5 There are several slide bars 55, which are evenly distributed in a ring.
[0023] Furthermore, by setting the number of slide bars 55 to several, we can perform precise limiting treatment at multiple key positions of the metal ring 56. This multi-point limiting design can effectively ensure the stability of the metal ring 56 and prevent any shaking during use. This stability not only improves the safety performance of the equipment, but also makes the user feel more at ease and convenient during use.
[0024] Please see Figure 5 There are three waterproof rings 4, and all three waterproof rings 4 are slidably connected to the insertion groove 3.
[0025] Furthermore, by setting the number of waterproof rings 4 to several and inserting them into the inside of the insertion slot 3, we can form an effective sealing structure. This sealing design can effectively prevent water from seeping in, providing users with reliable waterproofing and enabling the device to be used normally in humid or underwater environments, greatly expanding the application scenarios and improving user convenience.
[0026] Please see Figure 3 There are several levers 52, which are evenly distributed in a ring.
[0027] Furthermore, by setting the number of locking blocks 53 to several, we can tightly clamp the limiting rings 61 together. This multi-point clamping design can effectively ensure the stability between the connector base 2 and the flexible DC connector 1, preventing any loosening or shaking, thereby providing users with a stable and reliable operating platform and ensuring the stability and safety of operation.
[0028] Please see Figure 4 One end of the spring 57 is fixedly connected to the surface of the limiting plate 54, and the other end of the spring 57 is fixedly connected to the surface of the metal ring 56.
[0029] Furthermore, by fixing one end of the spring 57 to the surface of the limiting plate 54, we can effectively support the metal ring 56 using the elasticity of the spring 57. This support design can ensure the stability of the metal ring 56 and prevent any shaking or displacement during use. This improved stability not only enhances the performance of the device but also makes it more reassuring and convenient for users, further improving the overall user experience.
[0030] The specific implementation process of this utility model is as follows: When performing the insertion and sealing operation of the flexible DC connector 1 and the connector base 2, the flexible DC connector 1 should first be accurately inserted into the left side of the connector base 2 to ensure a tight and seamless connection between the two. Next, the user needs to carefully place the special waterproof ring 4 into the insertion groove 3 between the flexible DC connector 1 and the connector base 2, ensuring that the waterproof ring 4 completely covers the internal space of the insertion groove 3 so that the elasticity of the waterproof ring 4 can achieve effective sealing protection. Subsequently, the user needs to slide the metal ring 56 to the right along the preset track until the metal ring 56 tightly presses the locking rod 52, so that the locking rod 52 can drive the locking block 53 to be firmly locked in the internal position of the locking groove 62. In this way, not only can the connection between the flexible DC connector 1 and the connector base 2 be fixed and reliable, but the stability between the connector base 2 and the flexible DC connector 1 can also be effectively guaranteed, so that the sealing and waterproof performance reaches an excellent level, thereby achieving a highly efficient waterproof effect and ensuring that a good sealing state can be maintained in various environments to prevent water infiltration.
