The utility model discloses an outstanding effect is: compared with the prior art, the lifting protective sleeve can be moved after the connecting end of the power connector body is inserted and electrified, so that the sealing ring is pressed on the wall surface of the connecting part to realize sealing, the power connector body is prevented from being polluted by external water or dust, normal use of the power connector body is guaranteed, and the service life of the power connector body is prolonged.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a partial plan view of the present invention.
The specific implementation mode is as follows:
in an embodiment, as shown in fig. 1 to 2, a power connector with a protective shell includes a power connector body 10, connection extension portions 1 are formed on four outer side walls of an upper portion of the power connector body 10, all the connection extension portions 1 are formed together to form a frame-shaped extension portion, adjusting bolts 2 are screwed on the connection extension portions 1 on the left side and the right side of the power connector body 10, the tops of the adjusting bolts 2 extend out of the connection extension portions 1 and are formed with rotating portions 21, and the bottom ends of the adjusting bolts 2 extend out of the bottom surfaces of the connection extension portions 1 and are mounted on the edge portions of a frame-shaped lifting block 3;
the outer side wall of the frame-shaped lifting block 3 is fixed on the inner side wall of the lifting protection sleeve 4, the power connector body 10 is inserted in the lifting protection sleeve 4, and a radial extending edge 41 is formed on the lower portion of the outer side wall of the lifting protection sleeve 4.
Furthermore, the bottom end of the adjusting bolt 2 is fixed with a limiting plate 22, the middle bottom surface of the limiting plate 22 is fixed with a positioning rod 23, the positioning rod 23 is inserted in a through hole formed in the corresponding connecting extension part 1, a limiting bottom plate 24 is formed at the bottom end of the positioning rod 23, and the corresponding connecting extension part 1 is located between the limiting bottom plate 24 and the limiting plate 22.
Further, a self-lubricating sealing layer 31 is fixed on the inner side wall of the frame-shaped lifting block 3, and the inner side wall of the self-lubricating sealing layer 31 is tightly attached to the outer side wall of the power connector body 10.
