Plate is arranged on the bottom of switchgear, and fixed support is arranged on bottom plate by bolt, and fixed support includes cable mounting hole, electricity
Cable is fixed in cable mounting hole, and rubber seal is set between cable and cable mounting hole.
As prioritization scheme of the present utility model, rubber sealing boot is annular, is set in annular jagged.
As prioritization scheme of the present utility model, rubber sealing boot also includes male cone (strobilus masculinus) and cable punching hole, and male cone (strobilus masculinus) is set
In the outer shroud of rubber sealing boot, cable punching hole is arranged on the inner ring of rubber sealing boot.
As prioritization scheme of the present utility model, cable mounting hole is reverse taper hole.
The utility model has positive effect：1) the utility model is simple in construction, overall mechanical strength is big, cable is normal
It is combined into one in the case of rule with the sealing after the completion of the fixation and assembling of fixed installation beam, and the unfavorable factors such as gravity is converted to
Sealing and fixed favorable factor, assembling is simple, and efficiency of assembling is high, overall fixation, good airproof performance；
2) high mechanical strength of the utility model itself, while the surface area of cable bearing is big, the damage of cable outer layer
Less, the change strong adaptability to cable size, the scope of application are more extensive.

Embodiment
As shown in figures 1 to 6, the utility model discloses a kind of self-tightening type fixing seal device of cable in switchgear, bag
Fixed support 2, rubber sealing boot 3, bolt 4 and bottom plate 5 are included, bottom plate 5 is used for the inlet wire of cable 1 and outlet, bottom plate 5 are arranged on out
The bottom of equipment is closed, fixed support 2 is arranged on bottom plate 5 by bolt 4, and fixed support 2 includes cable mounting hole 21, cable 1
It is fixed in cable mounting hole 21, rubber sealing boot 3 is arranged between cable 1 and cable mounting hole 21.
As shown in Figure 3-4, fixed support 2 also includes base installing hole 22, and bolt 4 is arranged in base installing hole 22.Its
In, the circular hole of the disengaging of cable 1 and the mounting hole corresponding with base installing hole 22 are provided with bottom plate 5, during assembling, with bolt 4
Fixed support 2 is arranged on bottom plate 5
The bottom of fixed support 2 is circle, and base installing hole 22 is four, and base installing hole 22 is symmetrically arranged on two-by-two
The bottom of fixed support 2.
The section shape of fixed support 2 is I-shaped.
Rubber sealing boot 3 is annular, and jagged 31 are set in annular.
As seen in figs. 5-6, rubber sealing boot 3 also includes male cone (strobilus masculinus) 32 and cable punching hole 33, and male cone (strobilus masculinus) 32 is arranged on rubber
The outer shroud of sealing shroud 3, cable punching hole 33 are arranged on the inner ring of rubber sealing boot 3.
Bolt 4 is hexagon-headed bolt.
Cable mounting hole 21 is reverse taper hole.
Bolt 4 carries out fastening assembling by spring washer or plain cushion.
During assembling, first fixed support 2 is arranged on bottom plate 5 with 4 sets of bolts 4,4 supporting spring washer of bolt or plain cushion, bolt 4
In base installing hole 22, and assemble fastening；By cable 1 through the cable mounting hole 21 on fixed support 2, because quality compared with
Rubber sealing boot 3 for softness is provided with breach 31, is opened at the breach 31 of rubber sealing boot 3, is covered from the top of fixed support 2
