Abstract
The utility model discloses a plug type prefabricated cable terminal, which comprises a cable branch box binding post and a cable terminal T-shaped head for being connected with a cable. One end of a horizontal section of the cable terminal T-shaped head is connected with the cable branch box binding post in inserted mode. The plug type prefabricated cable terminal is characterized in that a connecting bolt is arranged in the horizontal section of the cable terminal T-shaped head. A binding post of the cable is inserted in the cable terminal T-shaped head from a lower port of the cable terminal T-shaped head and sleeved on the connecting bolt, one end of the connecting bolt is in threaded connection with the cable branch box binding post, an insulation plugging head is in inserted connection with the other end of the horizontal section of the cable terminal T-shaped head, and an inner hole of the insulation plugging head is in inserted connection with the other end of the connecting bolt. The plug type prefabricated cable terminal has the advantages of being simple in structure, convenient to use and capable of achieving grounding by using a spindle head at the other end of the connecting bolt after pulling off the insulation plugging head, simplifying grounding mode during maintenance of power distribution cable lines, reducing blackout range and operation range, facilitating line maintenance, and improving power supply reliability of the lines.
