Description

Technical Field

[0001] This invention belongs to the field of connector technology, specifically a high-power waterproof connector with an active heat dissipation structure. Background Technology

[0002] High-power waterproof connectors are electrical connection components used in energy storage, new energy fast charging equipment, and high-power motors for heavy engineering machinery. They consist of male and female connectors that plug into each other. Inside, they are equipped with large-section conductive copper components to carry high currents and transmit power and control signals. The overall design features a multi-layer rubber sealing structure to achieve waterproof and dustproof protection. Under high current operation, the conductive terminals continuously generate heat, so the industry generally uses built-in cooling fans to form an active cooling structure. By opening cooling air channels and vents, hot and cold air exchange is completed, thereby reducing the internal operating temperature of the connector.

[0003] However, conventional heat dissipation vents are fixed and always open, remaining open regardless of the internal temperature of the connector. Rainwater, cutting fluid, and dust can easily seep into the connector through the open vents, damaging the sealed and protective environment of the internal conductive components, significantly reducing the overall waterproof rating of the connector, and making it prone to internal short circuits and copper pin corrosion in outdoor, oily, and humid conditions.

Multiple strip grooves are provided at equal angles on the inner side of the hollow ring, and the bottom end of the air inlet pipe is fixedly connected to the hollow ring.

[0009] Preferably, a vertical plate is fixedly connected to the top of the connector housing, and side rods are fixedly connected to both sides of the vertical plate.

[0011] Preferably, a sliding rod is fixedly connected to the side of the sealing plate near the vertical plate, and a slider is movably sleeved on the outside of the sliding rod. The side of the horizontal plate away from the vertical plate is rotatably connected to the slider.

[0012] Preferably, a U-shaped rod is fixedly connected to the side of the translation plate away from the upright plate, an abutment cylinder is fixedly sleeved on the outer middle of the U-shaped rod, a sliding plate is movably sleeved on the outer side of the U-shaped rod, a movable plate is rotatably connected to the top of the sliding plate, and the top of the movable plate is rotatably connected to the outer side of the sealing plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 2. This invention can drive the horizontal plate to move by activating the electric push rod, which facilitates the movement of the sealing plate and the translation plate.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1, by Figures 1-7 The present invention relates to a high-power waterproof connector with an active heat dissipation structure, comprising a connector housing 1, a plurality of heat dissipation fins fixedly disposed on the outer wall of the connector housing 1, a female connector 11 fixedly installed inside the connector housing 1, a mounting plate 6 provided on the outer side of the connector housing 1, a sealing ring 5 and a male connector 12 fixedly installed on the mounting plate 6, the male connector 12 being inserted into the female connector 11, and the sealing ring 5 being fitted against the outer wall of the connector housing 1, the sealing ring 5 being used to ensure the sealing between the mounting plate 6 and the connector housing 1, and a waterproof mechanism 2 provided on the top of the connector housing 1, the waterproof mechanism 2 being provided with a cleaning mechanism 3.

[0031] In Embodiment 2, based on Embodiment 1, the waterproof mechanism 2 includes a sealing plate 201 located at the top of the connector housing 1. Sealing rings 2016 are fixedly connected to both sides of the sealing plate 201. An air outlet pipe 7 is fixedly connected to the top of the connector housing 1. An air inlet pipe 15 is provided at the top of the connector housing 1. An air inlet duct 16 is fixedly connected to one end of the air inlet pipe 15. A cooling fan 19 is fixedly installed inside the air inlet duct 16. An installation ring 18 is fixedly connected to the end of the air inlet duct 16. A filter screen 17 is fixedly connected to the inner side of the installation ring 18. The two sealing rings 2016 are respectively fitted to the installation ring 18 and the air outlet pipe 7. Two inclined blocks 8 are fixedly connected to the inner top wall of the connector housing 1. The connection between the air outlet pipe 7 and the connector housing 1 is located between the two inclined blocks 8. By setting the two inclined blocks 8, a flow guiding function is provided, facilitating the rapid discharge of hot air from the connector housing 1 through the air outlet pipe 7. A hollow ring 10 is provided inside the connector housing 1. The outer side of the hollow ring 10 is flush with the inner bottom wall of the connector housing 1. The symmetrical fixed connector has two support pillars 13. Multiple strip grooves 14 are provided at equal angles on the inner side of the hollow ring 10. The bottom end of the air inlet pipe 15 is fixedly connected to the hollow ring 10. A vertical plate 2010 is fixedly connected to the top of the connector housing 1. Side rods 209 are fixedly connected to both sides of the vertical plate 2010. Side blocks 208 are fixedly connected to the ends of the two side rods 209 away from the vertical plate 2010. A sliding plate 203 is movably sleeved between the two side rods 209. A sealing plate 201 is installed on the sliding plate 203. On the upper part, an electric push rod 2012 is fixedly installed on the side of the upright plate 2010 near the sealing plate 201. A horizontal plate 2011 is fixedly connected to the output end of the electric push rod 2012. The horizontal plate 2011 is connected to the sealing plate 201. A temperature sensor 9 is fixedly installed inside the connector housing 1. A control box 4 is fixedly installed on the top of the connector housing 1. A controller is fixedly installed inside the control box 4. The temperature sensor 9 is electrically connected to the controller, and the controller is electrically connected to the electric push rod 2012.

[0032] First, the temperature sensor 9 collects the internal cavity temperature of the connector housing 1 in real time and transmits it to the controller in the control box 4. When the connector housing 1 is working at low temperature, it relies on the heat dissipation fins on the outer wall of the connector housing 1 to naturally conduct and dissipate the small amount of heat generated by the conductive terminals. When the internal temperature rises to the set threshold, the controller outputs a control signal to start the cooling fan 19 and the electric push rod 2012.

[0033] When the electric push rod 2012 is running, it drives the horizontal plate 2011 to move and the sealing plate 201 to move. At the same time, the translation plate 203 slides along the two side rods 209 to ensure the stability of the sealing plate 201 when it moves, so that the two sealing rings 2016 are respectively separated from the mounting ring 18 and the air outlet pipe 7 and the air duct is opened.

[0034] When the cooling fan 19 is started, the outside air enters the air inlet duct 16 after being filtered by the filter screen 17. Then the air enters the hollow ring 10 through the air inlet pipe 15 and is discharged from each strip groove 14. At the same time, the hot gas inside the connector housing 1 is discharged from the air outlet pipe 7, realizing active heat dissipation and cooling inside the connector housing 1.

[0035] Once the temperature drops to a safe range, the controller shuts off the cooling fan 19 and drives the electric push rod 2012 to move the sealing plate 201 in the opposite direction, so that the two sealing rings 2016 fit into the mounting ring 18 and the air outlet pipe 7 respectively, completely sealing the air inlet pipe 16 and the air outlet pipe 7, preventing moisture and dust from seeping into the cavity from the air duct, and ensuring the overall waterproof and sealing performance of the connector.

[0036] In Embodiment 3, based on Embodiment 1, a mounting groove 2018 is provided on the top of the translation plate 203. A support shaft 2017 is rotatably connected to the inner side of the mounting groove 2018. A sealing plate 201 is fixedly sleeved on the outer side of the support shaft 2017. Two abutment blocks 2013 are symmetrically fixedly connected to the side of the translation plate 203 near the vertical plate 2010. The side of the sealing plate 201 near the vertical plate 2010 abuts against the two abutment blocks 2013. A sliding rod 2014 is fixedly connected to the side of the sealing plate 201 near the vertical plate 2010. A slider 2015 is movably sleeved on the outer side of the sliding rod 2014. The side of 2011 away from the vertical plate 2010 is rotatably connected to the slider 2015. The side of the translation plate 203 away from the vertical plate 2010 is fixedly connected to a U-shaped round rod 206. The outer middle of the U-shaped round rod 206 is fixedly sleeved with an abutment cylinder 204. The outer side of the U-shaped round rod 206 is movably sleeved with a slide plate 205. The top of the slide plate 205 is rotatably connected to a movable plate 202. The top of the movable plate 202 is rotatably connected to the outer side of the sealing plate 201. Two springs 207 are symmetrically fixedly connected between the slide plate 205 and the translation plate 203. Both springs 207 are sleeved on the outer side of the U-shaped round rod 206.

[0037] When the electric push rod 2012 extends, it drives the horizontal plate 2011 to move and the sealing plate 201 to move. At the same time, the translation plate 203 slides along the two side rods 209. When the translation plate 203 abuts against the two side blocks 208, the horizontal plate 2011 continues to move, driving the slider 2015 to slide along the slide rod 2014, causing the sealing plate 201 to rotate around the support shaft 2017. At the same time, the movable plate 202 drives the sliding plate 205 to slide along the U-shaped round rod 206, and both springs 207 deform until the sliding plate 205 abuts against the abutting cylinder 204, realizing the movement and tilting of the sealing plate 201 and removing it from the end position of the air inlet duct 16 and the air outlet duct 7, thereby improving the heat dissipation effect.

[0038] When the electric push rod 2012 retracts, it moves the horizontal plate 2011 and causes the slider 2015 to slide along the slide rod 2014, pulling the sealing plate 201. At the same time, under the elastic force of the two springs 207, the sealing plate 201 is pushed, causing the sealing plate 201 to rotate until it abuts against the two abutting blocks 2013. At this time, the sealing plate 201 is in a vertical state. Then the horizontal plate 2011 continues to move, causing the sealing plate 201 and the translation plate 203 to move simultaneously until the two sealing rings 2016 are respectively attached to the mounting ring 18 and the air outlet pipe 7, finally achieving complete sealing of the air inlet pipe 16 and the air outlet pipe 7 for waterproofing.

[0039] In Example 4, based on Example 1, the cleaning mechanism 3 includes a guide rod 301 fixed between the upright plate 2010 and the connector housing 1. A guide plate 302 is movably sleeved on the outer side of the guide rod 301. A bracket 304 is fixedly connected to the outer side of the guide plate 302. A roller 303 is provided at the bottom of the bracket 304 and located at the top of the connector housing 1. The roller 303 is used to support the bracket 304 and ensure the stability of the bracket 304 when it moves. A brush plate 306 is fixedly connected to the bracket 304. A movable rod 305 is rotatably connected to the outer side of the guide plate 302. The end of the movable rod 305 away from the guide plate 302 is rotatably connected to the outer side of the translation plate 203.

[0040] When the translation plate 203 slides along the two side rods 209, the movable rod 305 drives the guide plate 302 to slide along the guide rod 301, and drives the bracket 304 to move. At the same time, the brush plate 306 moves to clean the surface of the filter screen 17. Finally, the filter screen 17 can be cleaned without disassembling it, thus avoiding clogging of the filter screen 17 and improving the heat dissipation effect.
