The device of the explosion-proof performance of the explosion-proof form of the equipment.
The most of flame-proof mine electrical equipment produced at present, cable entry mode mostly use greatly press disc type cable to draw
Enter device screw and connect platen with pedestal, adjusts the pressing force of platen with screw to oppress sealing ring come hermetically-sealed cable, this
Kind method structure is relative complex, meanwhile, it is easy that cable is caused to damage.The clamping force of another cable unit comes from clamping element
Extruding to sealing ring makes sealed ring deformation to hold tightly to cable；So in order to ensure the sealing of flame proof cable entry
Performance, it is necessary to sealing ring be made to generate enough enclasping forces to cable.When sealing ring holds cable tightly, it is extruded on the outside of sealing ring,
So that holding cable on the inside of sealing ring tightly.But sealing ring outer surface is when being extruded, sealing ring be easy due to squeezing that deformation occurs by
Damage, the sealing ring after being extruded lack screen resilience due to damage and are difficult to carry out secondary use.
In consideration of it, overcoming defect present in the above-mentioned prior art is the art urgent problem to be solved.
Utility model content
The technical issues of the utility model solves is to provide a kind of a kind of cable entry for protecting rubber seal.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of cable entry comprising use
Connector pedestal in connection installation equipment, connector pedestal one end inside are provided with rubber seal, the rubber seal
It encloses one end far from connector pedestal and is provided with pressure ring, the pressure ring is provided with far from one end of rubber seal for screwing rubber
The lock nut of sealing ring, the connector pedestal between lock nut and rubber seal, the rubber seal with connect
The side of head pedestal interior side contacts is provided with arc-shaped notch.
Further, the pressure ring is provided with close to one end of lock nut for being spaced the convex of pressure ring and lock nut
The portion of rising, the lug boss are contacted with lock nut, form cavity by lug boss between the pressure ring and lock nut.
Further, the lock nut is provided with the limit to lug boss limit far from one end of rubber seal
Portion.
Further, the connector pedestal other end is provided with protruding ring, the protruding ring is far from rubber seal
One end is disposed with rubber ring and the nut for fixing rubber ring, and the rubber ring is between protruding ring and nut, institute
State protruding ring and nut clamping rubber ring.
Further, the connector pedestal be provided with inwardly close to one end of rubber seal it is close for baffle rubber
The groove of seal.
The beneficial effects of the utility model are: when rubber seal outer surface is extruded, two end in contact of arc-shaped notch, rubber
Sealing ring outer surface is shunk by arc-shaped notch, avoids sealing rubber ring from being damaged because squeezing due to deformation occurs, after squeezing
Rubber seal carry out secondary use；Setting lug boss makes
Lock nut locking rubber seal leaves reserved space, expands the cable scope of application；Limiting section is arranged to limit lug boss
Position；Convenient for fixed cable entry；Groove is set and is convenient for baffle positioning rubber sealing ring.
Detailed description of the invention
Fig. 1 is a kind of assembling schematic diagram of cable entry.
A kind of schematic diagram of the exploded view of cable entry in the position Fig. 2.
In the figure, it is marked as connector pedestal 1, rubber seal 2, pressure ring 3, lock nut 4, arc-shaped notch 5, lug boss 6, sky
Chamber 7, limiting section 8, protruding ring 9, rubber ring 10, nut 11, groove 12.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As depicted in figs. 1 and 2, a kind of cable entry comprising for connecting the connector pedestal 1 in installation equipment,
Rubber seal 2 is connected on the inside of described 1 one end of connector pedestal, the rubber seal 2 is socketed far from one end of connector pedestal 1
There is pressure ring 3, the pressure ring 3 is connected with the lock nut for screwing rubber seal 2 far from the threaded one end of rubber seal 2
4, the connector pedestal 1 is between lock nut 4 and rubber seal 2, the rubber seal 2 and 1 inside of connector pedestal
The side one molding of contact forms arc-shaped notch 5.
In use, 2 outer surface of rubber seal is extruded when screwing lock nut 4, so that 5 liang of end in contact of arc-shaped notch,
2 outer surface of rubber seal is shunk by arc-shaped notch 5, avoid sealing rubber ring 2 due to outer surface is extruded that deformation occurs by
Damage, carries out secondary use convenient for rubber seal 2 after extruding.2 outer surface of rubber seal is made by the contraction of arc-shaped notch 5
It obtains 2 inner surface of rubber seal to shrink, to hold cable tightly.
As depicted in figs. 1 and 2, the pressure ring 3 is formed close to one end one molding of lock nut 4 for being spaced pressure ring
3 contact with lock nut 4, pass through between the pressure ring 3 and lock nut 4 with the lug boss 6 of lock nut 4, the lug boss 6
Lug boss 6 forms cavity 7.Setting lug boss 6 make between pressure ring 3 and lock nut 4 there are gap formed cavity 7, for locking
Nut 4 locks rubber seal 2 and leaves reserved space, expands the cable scope of application.
As depicted in figs. 1 and 2, the lock nut 4 is formed far from one end one molding of rubber seal 2 to protrusion
The limiting section 8 that portion 6 limits.Limiting section 8 limits lug boss 6 far from one end of rubber seal 2, convenient for assembling and avoiding protrusion
Portion's deviation in contraction process influences the enclasping force to cable.
As depicted in figs. 1 and 2,1 other end one molding of connector pedestal forms protruding ring 9, and the protruding ring 9 is remote
