[0054] As Figures 1 to 7 shown, in an exemplary embodiment of the present invention, an electrical connection assembly 100 is disclosed. The electrical connection assembly 100 includes: a seal 1, a cable 2, a charging terminal 3, a temperature sensor 4, and a sealing plug 5. The seal 1 is formed with a cable through hole 101 and a jack 102 separated from the cable through hole 101. The cable 2 passes through the cable through hole 101 and is in interference fit with the cable through hole 101 to achieve sealing between the seal 1 and the cable 2.

In this way, the pulling force applied to the lead 41 can be effectively prevented from being transmitted to the body 40 of the temperature sensor 4, so that the body 40 of the temperature sensor 4 is not affected by the pulling force applied to the lead 41.

[0059] As Figures 1 to 7 shown, in the illustrated embodiment, the positioning flange 5a has a front side and a rear side that are axially opposite to each other on the sealing plug 5.

[0064] Figure 8 and Figure 9 The second embodiment shown in Figures 1 to 7 differs from the first embodiment shown in

[0065] only in the way the sealing plug 5 is arranged on the lead 41. Figure 8 and Figure 9 shown, in the illustrated embodiment, the sealing plug 5 is assembled to the lead 41 of the temperature sensor 4. In this way, the position of the sealing plug 5 can be adjusted.
