[0025] Next, the embodiments of this specification are described in detail.

[0026] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0028] Please refer to Figures 1 to 5 As shown, the present application provides a connector 5 for installation on an electrical device 6. The connector 5 comprises a base, a water barrier 3, and conductive terminals (not shown). The base defines a receiving cavity 10, which receives the conductive terminals. The water barrier 3 is disposed at one end of the base and is located within the electrical device. The water barrier 3 is used to isolate water from entering the electrical device 6.

[0029] The connector 5 provided in the present application is provided with a water barrier 3 at the base. The water barrier 3 is located inside the electrical device 6 and can isolate water entering the electrical device 6, thereby preventing damage to the interior of the electrical device 6 and improving the waterproof sealing effect of the connector 5.

[0030] The base includes a first base 1 and a second base 2. The first base 1 forms a receiving cavity 10, and the receiving cavity 10 is provided with a first opening 101 and a second opening 102 which are oppositely arranged.

[0031] The second base 2 is fixed to the first base 1 and is located in the receiving cavity 10. The second base 2 can be fixed to the second opening 102 of the first base 1 by snapping, and the tail end 21 of the second base 2 passes through the second opening 102. The second base 2 is provided with a terminal hole 22 for receiving a conductive terminal.

[0032] The water barrier 3 defines a water storage chamber 30 and is provided with a window 31 communicating with the water storage chamber 30 . The tail end 21 is located in the water storage chamber 30 and its end is received in the window 31 . The water storage chamber 30 is used to store water flowing in through the second opening 102 .

[0033] The first opening 101 is used for inserting the plug connector 8 that is plugged into the connector 5. A sealing member (not shown) is provided at the first opening 101. When the connector 5 provided by the present application is connected to the plug connector 8, an interference fit is formed by squeezing the sealing member to prevent water from flowing into the second opening 102.

[0034] The sealing member described in the present application may be a material such as waterproof glue, a rubber sealing ring, a sealing strip, or other materials with a waterproof sealing effect, and the present application does not impose any restrictions on this.

[0035] The tail end 21 of the second base 2 passes through the second opening 102. The second base 2 and the first base 1 are split. When the first base 1 or the second base 2 is damaged, only the damaged first base 1 or the second base 2 needs to be replaced without replacing the entire connecting part 5, which can save costs.

[0036] The second base 2 and the first base 1 are split, and there is a gap between the tail end 21 and the groove wall forming the second opening 102. When the seal at the first opening 101 fails due to aging or other reasons, water may enter the receiving cavity 10 from the seal position of the first opening 101 and flow through the second opening 102. Since the other end of the connecting member 5 is usually fixed in the electrical device 6, it will affect the electrical appliance 7 inside the electrical device 6.

[0037] Therefore, the connecting member 5 provided in the present application is provided with a water barrier 3, which includes a water storage chamber 30. When the connecting member 5 is fixed to the electrical device 6, the water storage chamber 30 can store water that flows into the interior of the electrical device 6 through the second opening 102, thereby preventing damage to the interior of the electrical device 6 and improving the waterproof sealing effect of the connecting member 5.

[0038] In some embodiments, the second opening 102 is smaller than the first opening 101, and the second base 2 is inserted into the receiving cavity 10 from the first opening 101, so that the second base 2 can be inserted into the receiving cavity 10 from the first opening 101, and the tail end 21 of the second base 2 passes through the second opening 102, thereby being fixed on the first base 1, making assembly easier and more efficient.

[0039] In some embodiments, the second opening 102 may be equal to or larger than the first opening 101. The second base 2 is assembled from the other side of the second opening 102. The other end of the second base 2 relative to the tail end 21 passes through the second opening 102 and enters the receiving cavity 10.

[0040] The first base 1 includes a main body 11 and a fixing portion 12 extending outward from one end of the main body 11. The main body 11 defines a receiving cavity 10. The second base 2 is fixed to the fixing portion 12.

[0041] The water barrier 3 is fixed to the tail end 21 and sealed to the tail end 21 to prevent water in the water storage chamber 30 from flowing into the electrical device 6 through the gap between the water barrier 3 and the tail end 21, thereby improving the waterproof sealing performance of the electrical device 6.

[0042] The fixing portion 12 is provided with a mounting groove 123 , and the water blocking member 3 is snapped onto the fixing portion 12 through the mounting groove 123 .

[0043] In some embodiments, the water barrier 3 is detachably connected to the tail end 21 and the fixing portion 12 to facilitate replacement of the water barrier 3 .

[0044] In some embodiments, the water barrier 3 can be made of plastic waterproof materials such as PVC, PC, or PP, and this application does not impose any restrictions on this.

[0045] Since the water storage chamber 30 stores water flowing in through the second opening 102, when the water storage chamber 30 stores excessive water, the stored water will cause a certain pressure on the water barrier 3. At this time, since the water barrier 3 is detachably connected to the tail end 21 and the fixing part 12, it is only necessary to disassemble the water barrier 3 and drain the water in the water storage chamber 30, which can increase the service life of the connecting part 5.

[0046] The connector 5 provided in the present application further includes a sensor 4. The sensor 4 is disposed in the water storage chamber 30 to detect the amount of water in the water storage chamber 30.

[0047] The sensor 4 provided in the present application can be a humidity sensor, which detects the humidity in the water storage chamber 30 and transmits the detected humidity to the processor to convert the water volume in the water storage chamber 30, thereby monitoring the water volume stored in the water storage chamber 30 in real time. When the water volume in the water storage chamber 30 exceeds a predetermined value, a prompt can be issued to remind that the water in the water storage chamber 30 needs to be drained; at the same time, it can also indicate whether the connecting part 5 has entered water. For devices with multiple connecting parts 5 installed, it can be convenient to check which connecting part 5 needs to be replaced, thereby improving maintenance efficiency.

[0048] The sensor 4 provided in this application may also be other types of sensors, and this application does not impose any limitation on this.

[0049] The present application further provides an electrical device 6 comprising a housing 61 and the aforementioned connector 5. The housing 61 defines a receiving space 60, the first base 1 being fixed to the housing 61, and the housing 61 having a through-hole 611 for the tail end 21 to pass through. The water barrier 3 is located within the receiving space 60.

[0050] A variety of electrical appliances 7 such as batteries and motors are usually installed in the storage space 60 of the electrical device 6. Once water flows into the storage space 60 through the second opening 102 of the connector 5, it will cause corrosion, short circuit and other damage to the electrical appliances 7 in the storage space 60. Therefore, the connector 5 of the present application is provided with a water barrier 3, and the water barrier 3 forms a water storage chamber 30. The water storage chamber 30 is used to store water flowing in through the second opening 102, thereby improving the waterproof sealing performance of the electrical device 6.

[0051] The fixing portion 12 is provided with a plurality of first through holes 121 , and the housing 61 is provided with a plurality of second through holes. The first through holes and the second through holes are used for the fixing members 124 to pass through, so as to fix the fixing portion 12 to the housing 61 .

[0052] The fixing member 124 can be a bolt, or a pin, a retaining ring or other fixing member, and this application does not impose any limitation on this.

[0053] One of the fixing portion 12 and the housing 61 is provided with a protrusion, and the other is provided with a limiting groove 122 . The protrusion is located in the limiting groove 122 to limit the fixing portion 12 and prevent the connecting member 5 from falling off from the housing 61 .

[0054] In one embodiment, the electrical device 6 provided in this application may be a compressor, or may be a battery, a high-voltage distribution box, an all-in-one controller or other electrical device 6, and this application does not impose any restrictions on this.

[0055] The present application also provides a vehicle, including the above-mentioned electrical device 6. The connector 5 of the present application is installed on the electrical device 6 and can be used to connect to the compressor, battery, controller and other devices in the vehicle, and the present application does not limit this.

[0056] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
