Description

Technical Field

[0001] This utility model relates to a charging connector, specifically a high-power DC charging connector, and belongs to the field of charging equipment technology. Background Technology

[0002] A charging head is a charger that is conventionally powered by a battery. It is widely used in the field of lithium battery charging for various portable and handheld devices. Existing charging methods for new energy vehicles often use a stable connector inside the charging gun to ensure the stability of the power connection.

[0003] Chinese patent application publication number CN218351841U discloses a charging head for a charging station. This utility model uses the elastic deformation of a first spring to engage the locking rod with the locking hole on the outer wall of the charging head body. This method facilitates the insertion and removal of the charging head, and the insertion and removal port will not loosen after long-term use, thus preventing the charging gun from becoming loose and falling off, and protecting it.

[0004] While the solutions in the aforementioned patents can increase the stability of the charging gun connection, the charging head in these patents is not convenient for waterproofing the charging connection. When charging outdoors, rainwater will flow down the charging gun's casing into the car's charging port, and the circuit is prone to short circuits when exposed to water, posing a certain danger.

[0005] Therefore, a high-power DC charging connector is proposed here. Utility Model Content

[0008] Furthermore, the positioning component includes two springs fixed between the positioning block and the slot, the two springs being respectively disposed on both sides of the connecting rod, and the springs being located inside the slot.

[0009] Furthermore, the positioning assembly also includes a transmission wheel rotatably connected to the inner wall of the connecting sleeve. The surface of the transmission wheel is provided with a set of arc-shaped grooves, and the arc-shaped grooves are slidably connected to the periphery of the transmission shaft.

[0010] Furthermore, the positioning component also includes a rotating rod rotatably sleeved inside the support frame, one end of which is fixedly sleeved inside the transmission wheel, and the end of the rotating rod away from the transmission wheel rotatably passes through the support frame and is fixedly sleeved with the rotating wheel.

[0011] The support frame has a set of storage slots on its periphery, and a protective sleeve is provided on the periphery of the support frame. A support assembly for supporting the protective sleeve is provided inside the storage slots. The support assembly includes a positioning shaft fixed inside the storage slots. A limiting sleeve is rotatably sleeved around the positioning shaft. A telescopic rod is slidably sleeved inside the limiting sleeve. A support block is fixed to one end of the telescopic rod away from the limiting sleeve. A connecting block is rotatably connected to one side of the support block. The connecting block is fixed to the inner wall of the protective sleeve.

[0012] Furthermore, the support assembly includes a compression spring fixed between the support block and the limiting sleeve, and the compression spring is sleeved on the outside of the telescopic rod.

[0013] Furthermore, two sealing gaskets are fixed to the inner wall of the protective sleeve, and the sealing gaskets slide around the periphery of the support frame.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0027] Please see Figures 1-4 The present invention proposes the following implementation scheme: a high-power DC charging connector, including a support frame 1, a connecting sleeve 2 fixed at one end of the support frame 1, a positioning component 3 for fixing the charging connector is provided inside the connecting sleeve 2, the positioning component 3 includes three slots 31 opened on the periphery of the connecting sleeve 2, a connecting rod 32 is slidably sleeved inside each slot 31, a positioning block 33 is fixed at one end of the connecting rod 32, and the end of the connecting rod 32 away from the positioning block 33 slides through the connecting sleeve 2 and is fixedly sleeved with a drive shaft 39.

[0028] Please refer to this carefully. Figure 3 The positioning component 3 includes two springs 34 fixed between the positioning block 33 and the slot 31. The two springs 34 are respectively disposed on both sides of the connecting rod 32, and the springs 34 are located inside the slot 31.

[0029] The positioning assembly 3 also includes a transmission wheel 36 rotatably connected to the inner wall of the connecting sleeve 2. The surface of the transmission wheel 36 is provided with a set of arc-shaped grooves 37, and the arc-shaped grooves 37 are slidably connected to the periphery of the transmission shaft 39.

[0030] Please refer to this carefully. Figure 2 and Figure 3The positioning component 3 also includes a rotating rod 35 rotatably sleeved inside the support frame 1. One end of the rotating rod 35 is fixedly sleeved inside the transmission wheel 36, and the end of the rotating rod 35 away from the transmission wheel 36 rotatably passes through the support frame 1 and is fixedly sleeved with a rotating wheel 38.

[0031] In the above scheme, the rotating wheel 38 is manually rotated, and the transmission wheel 36 is driven to rotate inside the connecting sleeve 2 through the rotating rod 35. Through the cooperation between the transmission wheel 36, the arc groove 37 and the transmission shaft 39, the connecting rod 32 can be driven to slide inside the connecting sleeve 2, and the positioning block 33 can be moved together. At the same time, the spring 34 provides elastic support for the positioning block 33 to prevent the positioning block 33 from loosening when supported.

[0032] Please refer to this carefully. Figure 2 and Figure 4 A set of storage slots 4 are provided on the periphery of the support frame 1. A protective sleeve 5 is provided on the periphery of the support frame 1. A support component 7 is provided inside the storage slot 4 to support the protective sleeve 5. The support component 7 includes a positioning shaft 71 fixed inside the storage slot 4. A limiting sleeve 72 is rotatably sleeved on the periphery of the positioning shaft 71. A telescopic rod 73 is slidably sleeved inside the limiting sleeve 72. A support block 76 is fixed to one end of the telescopic rod 73 away from the limiting sleeve 72. A connecting block 74 is rotatably connected to one side of the support block 76. The connecting block 74 is fixed to the inner wall of the protective sleeve 5.

[0033] Please refer to this carefully. Figure 4 The support assembly 7 includes a compression spring 75 fixed between the support block 76 and the limiting sleeve 72, and the compression spring 75 is sleeved on the outside of the telescopic rod 73.

[0034] In the above scheme, through the cooperation between the protective sleeve 5, the connecting block 74 and the support block 76, the telescopic rod 73 can rotate around the positioning shaft 71 and slide inside the limiting sleeve 72. When the telescopic rod 73 moves to the other side of the positioning shaft 71, the protective sleeve 5 moves to the outside of the connecting sleeve 2. The position of the protective sleeve 5 can be supported by the compression spring 75 and the support block 76.

[0035] Two sealing gaskets 6 are fixed to the inner wall of the protective sleeve 5, and the sealing gaskets 6 slide around the outer periphery of the support frame 1.

[0037] In use, this invention involves connecting the connecting sleeve 2 on one side of the support frame 1 to the device requiring charging. The rotating wheel 38 is manually rotated, and the rotating rod 35 drives the transmission wheel 36 to rotate inside the connecting sleeve 2. Through the cooperation between the transmission wheel 36, the arc-shaped groove 37, and the transmission shaft 39, the connecting rod 32 can slide inside the connecting sleeve 2, causing the positioning block 33 to move as well. Simultaneously, the spring 34 provides elastic support for the positioning block 33, preventing it from loosening during support and improving the stability of the connection when using the connector. The reverse rotating wheel 38, through the rotating rod 35, the transmission wheel 36 and the connecting rod 32, can make the positioning block 33 embedded in the slot 31, making it easy to take out the connector. After the connection is completed, the sliding protective sleeve 5, through the cooperation between the protective sleeve 5, the connecting block 74 and the support block 76, can make the telescopic rod 73 rotate around the positioning shaft 71 and slide inside the limiting sleeve 72. When the telescopic rod 73 moves to the other side of the positioning shaft 71, the protective sleeve 5 moves to the outside of the connecting sleeve 2. The position of the protective sleeve 5 can be supported by the compression spring 75 and the support block 76. The connection of the connecting sleeve 2 can be protected by the protective sleeve 5 and the sealing gasket 6, preventing external rainwater from entering the interior of the connecting sleeve 2 and improving the safety of the connector.
