Description
Technical field
The invention belongs to technical field of electric equipment, are related to a kind of improvement of electrical dustproof and waterproof sealing structure, more specifically
, it is a kind of dustproof waterproof sealing device imported and exported in equipment for cable or siphunculus.
Background technology
Currently, outdoors or dust it is more, have the occasion of spray, water drenching or water logging, such as outdoor occasion, port and pier, building
Electrical equipment is widely used in building site and other industrial use occasions, in these instances dust or ponding or the case where waterflooding
Generally existing.Since the degree of protection of environmental requirement is not achieved in the sealing of electrical equipment cable disengaging, water, which enters, electrically to be set
It is standby, it is be easy to cause short circuit, and cause safety accident, thus the protection of electrical equipment cable disengaging is proposed higher
It is required that degree of protection needs to reach IP68, soaking time must be amenable to 6 days（144 hours）More than.
Traditionally, the protection system of cable or siphunculus disengaging uses seal with elastometic washer, i.e., passes through pressure by bolt and its mounting base
Urgent rubber ring makes it deform and is adjacent in cable or siphunculus lateral surface, prevents the water from being invaded along cable or siphunculus lateral surface to reach
Effect, it is this simple in structure, easy to operation, it is the common encapsulating method of people all the time.
But outdoor occasion is frequently necessary to face the strong wind and heavy rain even immersion of flood, and the time impregnated is long,
Prolonged impregnate can cause sealing effect bad, and general Underwater Pressure meeting bigger, infiltration easily breaks through safeguard structure and enters
Electrical equipment easily makes electrical equipment short circuit break down, and in actual operation, it is above-mentioned that above-mentioned traditional method cannot be satisfied adaptation
The requirement that occasion uses.
Invention content
The invention aims to provide the sealing device of a kind of cable or siphunculus, it proposes that one kind changes for sealing device
Good structure can preferably cope with the various application scenarios of cable, be effectively prevented water and enter in electrical equipment.
The object of the present invention is achieved like this：
A kind of sealing device of cable or siphunculus, its main feature is that, in a tubular form, mounting base is formed with mounting base shape in bosom
Two cavitys in circular cone shape, two in the cavity of circular cone shape, its necking is opposite each other, and has pre- leave a blank between two neckings
Between, two in the cavity of circular cone shape, its flaring is then respectively facing mounting base two-port, and mounting base forms interior spiral shell at two-port
Line, two rubber rings are respectively placed in mounting base two-port, and two bolts are screwed in from mounting base two-port respectively, two rubber rings
Compression deformation and be respectively in two cavitys in circular cone shape, and formed between two rubber rings in reserved space slow
Rush ring cavity.
The sealing device of thus obtained cable or siphunculus, when use cable or siphunculus system from the center through hole of two bolts,
Among mounting base reserved space and the center through hole of two rubber rings passes through, and is tightly attached to by the gradual deformation of two rubber rings and respectively electricity
On the outside of cable or siphunculus, meanwhile, buffering ring cavity is then centered around the surrounding on the outside of cable or siphunculus, and when two rubber rings constantly closely to
Buffering ring cavity can taper into when centre squeezes, and so that the hollow air pressure of buffering ring cavity is gradually increased by force and be more than atmospheric pressure.
In this way, using two rubber rings, buffering ring cavity and the atmospheric pressure for buffering ring cavity, can play prevents dust/water
Entrance or mitigate dust/water pressure effect, sealing effect can be more preferable, and degree of protection can reach IP68.
The sealing device of this cable or siphunculus is just realized the assembling structure of double seals with elastometic washer, can be risen in the same apparatus
To double protective action, and simple in structure, manufacture is easy, and cost of manufacture increase is also few, can adapt to various special
It is used under occasion, is effectively prevented the entrance of dust or water.
The sealing device of cable or siphunculus of the present invention due to foring buffering ring cavity between two rubber rings, and is assembling
When create higher air pressure in buffering in ring cavity, therefore, the work of water penetration can be further prevented using higher air pressure
With making extraneous water be not easy to infilter sealing channel, further improve the sealing effect of device.
The sealing device of the invention cable or siphunculus, buffering ring cavity can also play release of pressure to the water for leaking into or penetrating into
Effect, even if extraneous have rubber ring outside a small amount of water breakthrough to enter buffering ring cavity, the pressure of water will be released, so as to subtract
Pressure of the light-water to internal rubber ring.
The sealing device of cable or siphunculus of the present invention makes the electricity of sealing due to the assembling structure using double seals with elastometic washer
Cable is supported by longer size, can be reduced the small inclinometer of cable support spot size and be influenced sealing performance, especially can
It is well adapted for the bad operating mode of installing environmental conditions.
It is preferred that in said program, gasket is additionally provided between rubber ring and bolt.In this way, bolt can pass through pad
Piece uniformly compresses rubber ring, and rubber ring is enable to be preferably bonded on mounting base inner wall.
Among the above, sealing device can make device by changing shape and inside dimension, inner via hole size, rubber loop diameter
The cable or siphunculus in various diameters are adapted to, the equipment or occasion of application are more extensive.
Among the above, device can select special material by change, so that it is adaptable to the occasion of requirements at the higher level or equipment, such as
Explosion-proof, diving and spacecraft etc..

Fig. 1 is that a kind of specific implementation mode of sealing device of cable or siphunculus of the present invention uses the sectional structure before unsealing
Schematic diagram.
Fig. 2 is the schematic diagram using the sectional structure after sealing using Fig. 1 sealing devices.
Specific implementation mode
Specific structure of implementing of the invention is described in detail below in conjunction with the accompanying drawings：
Referring to Fig.1, in present embodiment, the sealing device of cable or siphunculus, including 2, two, the gasket of mounting base 1, two
Rubber ring 3 and two bolts 4, in a tubular form, there are two be in circular cone shape in bosom formation for mounting base 1 for 1 shape of mounting base
Cavity 11, two are opposite each other in the cavity 11 of circular cone shape its necking, and have reserved space 11a between two neckings, two
In the cavity 11 of circular cone shape, its flaring is then respectively facing 1 two-port of mounting base, and mounting base 1 forms internal thread at two-port,
Two rubber rings 3 are respectively placed in 1 two-port of mounting base, and shell tool 2 respectively, and two bolts 4 are respectively from 1 both ends of mounting base
Mouthful screw in, two 3 compression deformation of rubber ring and be respectively in two cavitys 11 in circular cone shape.
With reference to Fig. 2, in use, cable or 5 system of siphunculus are from the center through hole of two bolts 4, the center through hole of two gaskets 2, peace
Among dress seat reserved space 11a and the center through hole of two rubber rings 3 passes through, and cable is tightly attached to respectively by two rubber rings, 3 deformation
Or 5 outside of siphunculus, meanwhile, buffering ring cavity is retained in cable or 5 outside of siphunculus between two rubber rings 3 in reserved space 11a
