By arranging the buffer assembly 2, when the power cable body 1 is bent and fixed, the buffer member 201 will first bear the bending force received by the power cable body 1 and initially buffer the bending force received by the power cable body 1, so that the bending force after being buffered by the buffer member 201 is transmitted to the buffer groove 202, enabling the buffer groove 202 to buffer the bending force received by the power cable body 1 again. This not only improves the safety of the power cable body 1 but also extends the service life of the power cable body 1.

[0033] As a preferred embodiment, the buffer groove 202 includes a guiding portion 2021 and a buffering portion 2022. The number of the guiding portions 2021 is two, the guiding portions 2021 are of an inclined structure, and the distance dimension between the ends of the two guiding portions 2021 close to the buffering portion 2022 is smaller than the distance dimension between the ends of the two guiding portions 2021 far from the buffering portion 2022; wherein, the buffering portion 2022 is of an arc structure. The bending force buffered by the buffer member 201 is transmitted to the guiding portion 2021 and, through the guiding action of the guiding portion 2021, acts on the buffering portion 2022, enabling the buffering portion 2022 to buffer the bending force received by the power cable body 1 again.

[0034] As a preferred embodiment, it further includes a pressure-bearing assembly 3; the pressure-bearing assembly 3 is arranged on the guiding portion 2021; wherein, the pressure-bearing assembly 3 includes a connecting member 301 and a pressure-bearing member 302; the connecting member 301 is fixedly arranged on the guiding portion 2021; the pressure-bearing member 302 is fixedly connected to the opposite ends of the two connecting members 301; wherein, the pressure-bearing member 302 is of an arc structure; wherein, the two connecting members 301 and the pressure-bearing member 302 form a bow-shaped structure, and the arching direction of the bow-shaped structure is outward.

[0036] Working principle

[0037] For the power cable that is convenient for bending and fixing, when bending and fixing the power cable body 1, the buffer member 201 will first bear the bending force received by the power cable body 1, and initially buffer the bending force received by the power cable body 1, so that the bending force after being buffered by the buffer member 201 is transmitted to the guiding portion 2021. Through the guiding action of the guiding portion 2021 on the buffering portion 2022, the buffering portion 2022 can buffer the bending force received by the power cable body 1 again. Moreover, when the guiding portion 2021 guides the bending force, a part of the bending force will be transmitted to the pressure-bearing member 302 through the connecting member 301, so that the pressure-bearing member 302 can further buffer the bending force, making the outer protective layer 101 more resistant.
