Wherein, the first raised portion 14 is detachably connected to the housing 1 and extends outward, so that the length of the first raised portion 14 extending outward can be replaced and adjusted, thereby avoiding interference; it is also convenient It is installed and connected in the housing 1 and extends inward.

In the second embodiment, the connecting head 22 protrudes into the first protruding portion 14 . A part of the structure of the connector 22 is located in the sheath 6 and extends into the first raised portion 14, further achieving a more compact structure and occupying less space.

The insulator 5 protrudes into the first protrusion 14 . Both ends of the insulator 5 are respectively connected to the pole mount 4 and the sheath 6 , and part of the structure of the insulator 5 will extend into the first protrusion 14 , further achieving a more compact structure and occupying less space.

Although the specific implementation of the utility model has been described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the present utility model, but these changes and modifications all fall within the protection scope of the present utility model.
