[0013] Referring to Figures 1-4 , the names of parts are as follows: upper layer box body 1, lower layer box body 2, partition 3, sealed box door 4, filter cotton 5, lower sealed box door 6, wire passing hole 7, fixed lug 8, nut 9, adjustable position angle steel 10, long hole 11, angle steel 12, steel quality cable waterproof joint 13, inlet and outlet wire hole 14, locking device 15.
[0014] Referring to Figure 1A terminal box with oil mist and acid / alkali resistance features includes a box body, which is divided into an upper box body 1 and a lower box body 2, with a partition 3 in between. The partition 3 has a wire passage hole 7 in the middle. The upper box body 1 has an openable sealed door 4, and the lower box body 2 has a lower sealed door 6 fixed by four corner bolts. Four nuts 9 are welded to the inside of the lower box body 2 at the four corners, allowing the lower sealed door 6 to be fixed to the lower box body 2 by bolts to ensure reliable sealing. The four corners of the box body have mutually perpendicular fixing ears 8 for easy fixing.
[0015] See Figure 2 , 4 The partition 3 has angle steel 12 on both sides of the cable passage hole 7 to clamp the cable. One of the angle steels is an adjustable angle steel 10 with three elongated holes 11 to allow the adjustable angle steel 10 to move relative to the angle steel 12 to clamp the cable between the angle steels. An oil mist filter cotton 5 is provided between the two angle steels to clamp the cable and block the cable passage hole 7.
