The second cover 121 covers the second housing 122 , and can protect the second housing 122 and structures such as the third sealing member 160 and the wiring harness terminal 300 located inside the second housing 122 .

[0055] In one possible implementation, see Figure 1 As shown, the first connector 110 is plug-connected with the second connector 120. Specifically, an elastic pressing buckle structure 1142 is provided on the housing 114 of the first connector 110. The elastic pressing buckle structure 1142 is located on the side of the first connector 110 facing the second connector 120. A second groove 1222 is provided on the second housing 122 of the second connector 120. The elastic pressing buckle structure 1142 is engaged with the second groove 1222 to connect the first connector 110 with the second connector 120. The housing 114 of the first connector 110 is sealed and connected to the second housing 122 of the second connector 120 through a fourth sealing member 170. The fourth sealing member 170 and the housing 114 are interference fit.

[0056] The present application also provides an electrical device 200, comprising a cylinder 210 and the connector assembly 100 described in any of the above embodiments, wherein the first connector 110 is connected to the cylinder 210, the first plug-in portion 111 of the first connector 110 can be inserted into the interior of the cylinder 210, and the first seal 130 seals the first plug-in portion 111 of the first connector 110 and the cylinder 210. The electrical device provided in the present application may include but is not limited to a motor, a battery, and a vehicle charger.

[0057] When the electrical device 200 provided in the present application is connected to the connector assembly 100, the cylinder body 210 of the electrical device 200 is sealed and connected to the first connector 110 through the first seal 130. The first seal 130 has two sealing parts. The first seal 131 and the second seal 132 are an integrated structure with better structural strength, which is not easy to deform during assembly and has a better sealing effect, thereby reducing the possibility of sealing failure, avoiding short circuit or corrosion of the internal circuit of the electrical device due to poor sealing, reducing the damage rate of the electrical device, and allowing the electrical device to maintain a stable working state under various environments.

[0058] In a possible implementation, the first sealing member 130 is sleeved on the first plug-in portion 111 , and the first sealing member 130 is interference fit with the cylinder body 210 . The first sealing member 130 is used to seal and connect the first plug-in portion 111 and the cylinder body 210 .
