Because first elasticity is embraced portion 41 and second elasticity and is embraced portion 42 integrated into one piece tightly, consequently, it is located terminal 32 both sides to embrace portion 41 and second elasticity as first elasticity and embrace portion 42 tightly to first elasticity is embraced the both ends that portion 41 and second elasticity are embraced portion 42 tightly and is linked to each other, and then produces to embrace power to terminal 32 tightly. Specifically, the first elastic clasping portion 41 and the second elastic clasping portion 42 are arranged along the extending direction of the posts 32, and a gap through which the posts 32 pass is formed on a plane perpendicular to the arrangement direction thereof. The clearance is an interference fit with the stud 32 (meaning that the size of the clearance is smaller than the radial size of the stud 32 in a state where the stud 32 is not inserted). Therefore, when the junction box cover 33 is closed, the clasping mechanism can generate clasping force on the binding post 32. The holding force between the holding mechanism of the wiring terminal 4 and the wiring terminal can further enhance the reliability of fixation between the junction box cover and the base body on the basis of the holding force generated by interference fit between the junction box cover and the base body.
Further, as shown in fig. 2 and 3, the junction box cover 33 further includes a power outlet 334, one end of the power outlet 334 extends into the top cover 331 of the junction box cover 33 and is electrically connected to the terminal 32, and the other end is used for connecting a power supply (not shown).
