Type is not construed as limiting this.
The first plugging structure 203 is burned during in order to more effectively prevent on fire in cable duct, makes fire spreading to terminal
In case, it is preferred that the area of the first fireprotection layer 205 is more than the area of bottom of box 201-1.
Referring to Fig. 3, Fig. 3 is the knot of the still another embodiment of lightning protection moisture-proof terminal box provided by the embodiments of the present application
Structure schematic diagram.
As shown in figure 3, a kind of lightning protection moisture-proof terminal box, except including：Babinet 201, be opened in the logical of bottom of box 201-1
Hole 201-2, the lightning protection moisture-proof terminal box further include：First plugging structure 203, the second plugging structure 206 and lightning rod 209.
Wherein, cable 202 is equipped with through hole 201-2.
Specifically, the first plugging structure 203, the inner surface for the bottom of box 201-1 that is laid in, and embedded through hole 201-
In gap between 2 and the cable 202 that is threaded through in through hole 201-2.Lightning rod 209 is installed on babinet by mounting seat 208
The outside of top 201-3.
Second plugging structure 206, the outer surface for the bottom of box 201-1 that is laid in, and embedded through hole 201-2 are with wearing
It is located in the gap between the cable 202 in through hole 201-2, an entirety is formed with the first plugging structure 203.
Preferably, the first plugging structure 203, the whole inner surface for the bottom of box 201-1 that is laid in, the second plugging structure
206, the whole outer surface for the bottom of box 201-1 that is laid in.
Likewise, in figure 3,204 represent ground, and babinet 201 is located on ground 204, is cable under ground 204
Ditch.
It can be appreciated that the inner and outer surfaces in bottom of box 201-1 lay plugging structure at the same time, and make the inner surface that is laid in
The first plugging structure 203 and the second plugging structure 206 of the outer surface that is laid in form the closure mode of an entirety, Ke Yijin
One step increases the contact area between plugging structure and babinet, so as to reduce further what is occurred between plugging structure and babinet
Via the possibility of through hole communication cable ditch, plugging effect is very tight in crack so that the moisture protection of terminal box is substantially improved.
Further, since it is mounted with lightning rod at the top of terminal box, therefore the terminal box is also equipped with lightning protection function.
Likewise, practical proof shows, the first plugging structure 203 on the inner surface of bottom of box 201-1 that is laid in
Thickness between 5mm~20mm when, can obtain good plugging effect.When the thickness is less than 5mm, plugging effect is not good enough,
During more than 20mm, although more preferable plugging effect can be obtained, the waste of plugging material is caused.
Further, since the presence of the first plugging structure 203, second on the outer surface of bottom of box 201-1 that is laid in
The thickness of plugging structure 206 can suitably reduce, between 1mm~20mm, laying it is too thick, plugging material can be caused
Waste.
In addition, plugging material used by the first plugging structure 203 and the second plugging structure 206, all can be conventional
Plugging material.Preferably, plugging material can be inorganic anti-used by the first plugging structure 203 and the second plugging structure 206
Fiery putty.
Also, in order to make the second plugging structure 206 and the first plugging structure 203, in through hole 201-2 and it is threaded through through hole
Strong bonded in the gap between cable 202 in 201-2, forms the entirety for being not easy to split, to strengthen plugging effect.It is excellent
Choosing, the first plugging structure 203 and the second plugging structure 206 can use identical plugging material.
Further more, alternatively, as shown in figure 3, lightning protection moisture-proof terminal box can also include：Be laid in the second plugging structure 206
Second fireprotection layer 207 of outer surface, during preventing on fire in cable duct, the second plugging structure 206 and the first plugging structure 203 are equal
It is burned, so as to avoid in fire spreading to terminal box.
As previously described first fireprotection layer 205, above-mentioned second fireprotection layer 207, can be specifically one layer of fire resistant coating,
Can also be one layer of fire barrier, the utility model is not construed as limiting this.
During in order to more effectively prevent on fire in cable duct, the first plugging structure 203 and the second plugging structure 206 are burnt
It is bad, cause in fire spreading to terminal box, it is preferred that the area of the second fireprotection layer 207 is more than the area of bottom of box 201-1.
In addition, as shown in Figures 2 and 3, a kind of lightning protection moisture-proof terminal box that any of the above-described embodiment provides can also include：Add
Hot dehydrating unit 210, the heating and dehumidification device 210 specifically may be mounted at least one side plate 201-4's of the babinet 201
