Abstract
Description
Technical Field
[0001] This utility model relates to the field of flexible DC connector technology, specifically a flexible DC connector with temperature monitoring function. Background Technology
[0002] Flexible DC connectors with temperature monitoring capabilities are developed from traditional flexible DC connectors and are mainly used in flexible DC transmission systems. They ensure stable current transmission while monitoring the temperature of connection points in real time, improving system operational safety. In flexible DC transmission systems, current transmission generates heat. Overheating at connection points can affect connector performance and lifespan, and even cause safety accidents. This connector with temperature monitoring can sense temperature changes at connection points in real time. Through a built-in monitoring module, it accurately acquires temperature data from the connection points. This temperature data is processed and analyzed promptly, and the system quickly issues an alarm signal if the temperature exceeds the normal range. Personnel can then take timely measures based on the alarm, such as checking for loose connections and adequate heat dissipation, to prevent equipment damage or power outages due to overheating. In practical applications, this connector is widely used in renewable energy power plants and urban power grids. In renewable energy power plants, it ensures stable DC power output; in urban power grids, it improves power supply reliability. The temperature monitoring function allows maintenance personnel to identify potential problems early and perform preventative maintenance, greatly improving the stability and safety of flexible DC transmission systems and reducing maintenance costs.
[0003] Flexible DC connectors with temperature monitoring capabilities suffer from insufficient stability during the insertion of the connector head and plug in practical applications. Loosening or misalignment can easily occur during insertion, leading to increased contact resistance. This not only affects the accuracy of temperature monitoring data but may also cause localized overheating due to poor contact, further threatening the reliability and safety of the connector during long-term operation. Utility Model Content
[0004] The purpose of this invention is to provide a flexible DC connector with temperature monitoring function, which solves the problem of unstable connection between the connector head and plug during use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible DC connector with temperature monitoring function, including a plug, a connector head inserted into the plug, a base disposed on the outside of the connector head, a monitor body disposed on the base, a fixing block fixedly connected to the outside of the plug, a limit sleeve rotatably connected to the outside of the fixing block, the limit sleeve being threadedly connected to the connector head, a positioning plate fixedly connected to the outside of the connector head, the positioning plate contacting the limit sleeve, a positioning rod fixedly connected to the left side of the positioning plate, and a limit mechanism disposed on the base.
[0006] Preferably, a protrusion is fixedly connected to the outer side of the plug, and the protrusion is slidably connected to the limiting sleeve. The protrusion can limit the movement of the limiting sleeve.
[0007] Preferably, the positioning rod contacts the limiting sleeve and the base. The positioning rod is designed to position the connector.
[0008] Preferably, the limiting mechanism includes a limiting frame, a limiting frame that is slidably sleeved on the outer side of the base, a limiting block that is fixedly connected to the outer side of the positioning rod, a slider that is fixedly connected inside the limiting frame, a sliding rod that is fixedly connected to the outer side of the slider, a limiting ring that is fixedly connected inside the base, and a spring that is provided on the outer side of the sliding rod. One end of the spring contacts the limiting ring, and the spring contacts the sliding rod. Through the design of the limiting mechanism, the limiting sleeve can be made more stable when limiting the connector.
[0009] Preferably, the limiting frame is in contact with the positioning rod, and the limiting frame is slidably connected to the limiting block. Through the design of the limiting frame, the positioning rod can be limited.
[0010] Preferably, the slider is slidably connected to the base, and the slide rod is slidably connected to the base. The design of the slider and slide rod can guide the limiting frame.
[0011] Preferably, the limiting ring contacts the slider and is slidably connected to the slide rod. Through the design of the limiting ring, the slide rod can be limited.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the coordinated structure of a limiting sleeve, a positioning plate, and a positioning rod, ensures that when the connector head and plug are inserted, the limiting sleeve axially limits the connector head, the positioning rod accurately guides and positions it, and the positioning plate assists in fixing it, thus ensuring accurate alignment and stable fit during the insertion process. This effectively solves the problem of poor contact caused by unstable insertion of the connector head and plug in existing flexible DC connectors with temperature monitoring functions, thereby improving the reliability of the connection.
[0013] 2. This utility model sets up a limit frame, a limit block and a spring linkage structure. The spring force drives the limit frame and the limit block to slide and fit together, so that the limit frame accurately locks the positioning rod, thereby forming a reliable limit on the limit sleeve. This ensures that the connector and plug are axially stable and radially non-offset when they are plugged in, effectively solving the problem of unstable plugging and improving the reliability of the connection and the convenience of operation.

[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 1-4 A flexible DC connector with temperature monitoring function includes a plug 1, a connector head 2 inserted inside the plug 1, a base 21 on the outside of the connector head 2, a monitor body 22 on the base 21, a fixing block 3 fixedly connected to the outside of the plug 1, a limiting sleeve 4 rotatably connected to the outside of the fixing block 3, the limiting sleeve 4 being threadedly connected to the connector head 2, a protrusion 5 fixedly connected to the outside of the plug 1, the protrusion 5 being slidably connected to the limiting sleeve 4, the protrusion 5 being designed to limit the limiting sleeve 4, a positioning plate 6 fixedly connected to the outside of the connector head 2, the positioning plate 6 contacting the limiting sleeve 4, a positioning rod 7 fixedly connected to the left side of the positioning plate 6, the positioning rod 7 contacting the limiting sleeve 4, the positioning rod 7 contacting the base 21, the positioning rod 7 being designed to position the connector head 2, and a limiting mechanism 8 being provided on the base 21.
[0018] Please see Figure 2-4 The limiting mechanism 8 includes a limiting frame 81. The limiting frame 81 is slidably sleeved on the outer side of the base 21. The limiting block 82 is fixedly connected to the outer side of the positioning rod 7. The limiting frame 81 contacts the positioning rod 7. The limiting frame 81 is slidably connected to the limiting block 82. Through the design of the limiting frame 81, the positioning rod 7 can be limited. The limiting frame 81 is fixedly connected to the inside of the limiting frame 81. The sliding rod 84 is fixedly connected to the outside of the sliding rod 83. The sliding rod 83 is slidably connected to the base 21.
[0019] Please see Figure 2-4 The slide bar 84 is slidably connected to the base 21. The design of the slider 83 and the slide bar 84 can guide the limiting frame 81. The base 21 is fixedly connected to the limiting ring 85. The limiting ring 85 is in contact with the slider 83 and is slidably connected to the slide bar 84. The design of the limiting ring 85 can limit the slide bar 84. A spring 86 is provided on the outside of the slide bar 84. One end of the spring 86 is in contact with the limiting ring 85 and the slide bar 84. The design of the limiting mechanism 8 can make the limiting sleeve 4 more stable when limiting the connector 2.
[0020] The specific implementation process of this utility model is as follows: In use, by moving the limiting frame 81 away from the base 21, the limiting frame 81 drives the slider 83 to move, and the slider 83 drives the slide rod 84 to slide in the limiting ring 85, so that the slide rod 84 squeezes the spring 86. Then, the connector 2 and the plug 1 are inserted, so that the connector 2 drives the positioning rod 7 on the positioning plate 6 to contact the base 21. Then, the limiting sleeve 4 is rotated, so that the limiting sleeve 4 and the connector 2 have a threaded movement, so that the limiting sleeve 4 plays a limiting role on the connector 2, and thus the connector 2 remains stable after being inserted into the plug 1. Then, by releasing the limiting frame 81, the spring force of the spring 86 can drive the slide rod 84 to move, which in turn drives the slider 83 to move, causing the slider 83 to reset the limiting frame 81. This allows the limiting frame 81 to engage with the limiting block 82 on the positioning rod 7, thus limiting the positioning rod 7 and the limiting sleeve 4, thereby ensuring the stability of the limiting sleeve 4 when limiting the connector 2.
