Description
Technical field
The utility model is related to a kind of environment-protection type outdoor terminal cable sealing structures.
Background technology
Environment-protection type outdoor terminal inner usually rely on nitrogen protection, therefore it is required that into cable one end of terminal have compared with
Good leakproofness to prevent from causing helium leak since sealing is bad, has an adverse effect to outdoor terminal service life.Tradition
Outdoor terminal mostly sealed in cable upstream end using O-ring seal, sealing effect is more general.
Invention content
The technical problems to be solved in the utility model is：In order to overcome deficiency in the prior art, the utility model provides
A kind of environment-protection type outdoor terminal cable sealing structure for effectively improving leakproofness, extending outdoor terminal service life.
Technical solution is used by the utility model solves its technical problem：A kind of environment-protection type outdoor terminal cable sealing
Structure has the mounting base for the terminal bodies bottom surface for being fixed on outdoor terminal, is fixed with cable fixing pipe on mounting base face, outside
The cable of portion's access after cable fixing pipe by penetrating in terminal bodies, between the cable fixing pipe upper surface and mounting base
Equipped with cable seal disk, the cable seal disk includes the disk body and sealing flange of integral structure, and disk body has and cable mistake
It is full of the sealing through-hole of cooperation, sealing flange outer ring has spherical bulge loop, and the spherical bulge loop is placed in cable fixing pipe upper surface
It is clamped between mounting base.
There is annular groove on the sealing flange between spherical bulge loop and disk body.
The beneficial effects of the utility model are：The utility model passes through the sealing through-hole of cable seal disk and the interference of cable
The collective effect of spherical bulge loop for coordinating and being clamped between cable fixing pipe and mounting base, preferably improves outdoor terminal
Internal sealing effect is conducive to extend the service life of outdoor terminal.
Description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of cable seal disk described in the utility model.
In figure：1. 4. cable of terminal bodies 2. mounting base, 3. cable fixing pipe, 5. cable seal disk 5-1. disk bodies 5-
2. sealing flange 5-3. seals the spherical bulge loop 5-5. annular grooves of through-hole 5-4.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
A kind of environment-protection type outdoor terminal cable sealing structure as shown in Figure 1 and Figure 2, it is eventually with outdoor terminal is fixed on
The mounting base 2 of 1 bottom surface of body is held, cable fixing pipe 3 is fixed on 2 face of mounting base, the cable 4 of outside access is consolidated by cable
It is penetrated after fixed tube 3 in terminal bodies 1.
Cable seal disk 5, the cable seal are equipped between 3 upper surface of cable fixing pipe and mounting base 2
Disk 5 includes the disk body 5-1 of integral structure and sealing flange 5-2, and axially there is disk body 5-1 the sealing being interference fitted with cable 4 to lead to
Hole 5-3, sealing flange 5-2 outer ring have spherical bulge loop 5-4, the spherical bulge loop 5-4 be located at 3 upper surface of cable fixing pipe and
Between mounting base 2, spherical bulge loop 5-4 is simultaneously clamped on when cable fixing pipe 3 is fixed on 2 face of mounting base, by spherical
The deformation that bulge loop 5-4 is clamped and generates, and play preferable sealing function.
Particularly, there is annular groove 5- on the sealing flange 5-2 between spherical bulge loop 5-4 and disk body 5-1
5 so that spherical bulge loop 5-4 deforms bigger when being clamped, to reach sealing more preferably effect.
The utility model is by the sealing through-hole 5- of cable seal disk 5 and the interference fit of cable 4 and is clamped in cable and consolidates
The collective effect of spherical bulge loop 5-1 between fixed tube 3 and mounting base 2, preferably improves the leakproofness inside outdoor terminal
Energy is conducive to extend the service life of outdoor terminal.
Using the above-mentioned desirable embodiment according to the utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
The content being not limited to novel technical scope on specification, it is necessary to which its technology is determined according to right
Property range.
