Line seal structure is crossed to block terminal

The utility model relates to a line seal structure is crossed to block terminal. It has solved current outdoor distribution box leakproofness subalternation problem. Wiring including setting up on the distribution box is uncovered, it is equipped with the connection terminal to work a telephone switchboard the uncovered outside, the wiring base is provided with a wire passing through hole, it is the pipy wire sleeve of mistake to cross interior being equipped with through mounting structure of line through -hole, and cross wire sleeve one end and cross the line through -hole and link to each other, the other end extends to the connection terminal outer end, it is equipped with and surrounds the toper that forms by the extension strip of a plurality of circumference settings and press from both sides tight barrel to cross the wire sleeve outer end, the microcephaly that tight barrel was pressed from both sides in the toper holds the circumference inboard to be equipped with a plurality of the bonding in extending the inboard flexible lining piece of strip, pressing from both sides tight barrel, the toper be equipped with the tight control structure of clamp that enables the microcephaly and hold the diameter to diminish gradually on. The advantage lies in: simple structure, stability is good, and the leakproofness is good, can prevent that the phenomenon from appearing leaking or seeping water in line department, and the installation of the cable of being convenient for is fixed.
