Description
Technical field
The present invention relates to underwater electric equipment waterproof sealing field, specifically one electrical equipment wire via hole waterproof seal under water.
Background technology
Electric equipment is under water time, for preventing water from must carry out good sealing along electric wire access arrangement, electric wire via (i.e. electric wire is through the hole within device housings access arrangement) place, playing waterproof, the effect of insulation.Meanwhile, at via, the design of waterproof sealing structure consideration is that interchangeability when electric wire is installed and length, the convenience of position adjustment and wire thicknesses change.
Existing electrical equipment wire via hole waterproof type generally has two big classes: a class is to cross hole site at electric wire electric wire to be connected and fixed in via by the way of cast is coated with certain macromolecular material, plays the effect of sealing.Chinese patent " a kind of waterproof plug " such as Patent No. 2011201601553 have employed this sealing structure.If the cast of this sealing structure needs more to rewire or reinstall after installing, then must destroy original structure and encapsulant, again pour into a mould, installation process bothers very much, maintainability energy extreme difference and be unfavorable for site installation test.
Another kind of is to go out specific structure in electric wire via Position Design and coordinate the suitable sealing member of employing to seal.Waterproof seal is often rubber cylindric or coniform, that profile is multilevel shape.The Chinese patent of Patent No. 2011103081810 " a kind of underwater optical cable connector " and Chinese patent application " one waterproof sealed cable connector " that number of patent application is 201010173072.8 all disclose such design of Sealing Structure mode.This method is relatively flexible, but must first strut sealing member when installing, and then by wire feedthrough sealing member, then makes sealing member retraction hold electric wire tightly to play sealing function.For ensureing to install the accuracy of location, it usually needs use special setting-in equipment to complete the assembling of electric wire and sealing member, cause assembling process sufficiently complex.In order to solve this problem, disclose in the Chinese patent application " electrical equipment wire via hole waterproof sealing structure and waterproof sealing method " that number of patent application is 201310064208.5 and a kind of use turnover conical resilient sealing shroud to carry out the via structure design sealed.Turnover sealing shroud can be suitably used for the electric wire of various outer diameter, but the highest to the performance requirement of material, easily occurs integrity problem during being dismounted for multiple times.
Summary of the invention
The technical problem to be solved is to overcome above-mentioned deficiency of the prior art, a kind of compact conformation is provided, assembling is simple, processing cost is low, each parts uniform force, good seal performance, reliability are high, can be applicable to the electric wire of various outer diameter within the specific limits, on-the-spot can lead to the electrical equipment wire via hole waterproof seal under water that line is fixing.
The present invention solves above-mentioned technical problem and the technical scheme is that one electrical equipment wire via hole waterproof seal under water, the round buss of integration vertically it is provided with on its electrical appliance shell body wall, described round buss upwards descends both sides to protrude along electrical appliance shell body wall, its upper and lower end has been threaded connection clamp nut respectively, it is characterized in that: in described round buss, be provided with an elastic packing ring set, described elastic packing ring set center is provided with electric wire through-hole, and upper and lower both ends of the surface are respectively equipped with a taper annular groove；It is respectively equipped with plug-in type pressure ring between the clamp nut of described elastic packing ring set and the upper and lower both sides of casing for electric appliances, it is respectively equipped with the annular corresponding with taper annular groove on described plug-in type pressure ring and inserts body, tighten clamp nut, clamp nut compressing plug-in type pressure ring puts corresponding taper annular groove to elastic sealing ring and moves, annular is inserted body and is inserted taper annular groove, elastic packing ring set is squeezed generation dilatancy, outer wall fits tightly with round buss inwall, internal wire through hole reduces holds electric wire tightly, it is achieved the waterproof sealing of electric wire via.
The vertical sectional shape of described elastic packing ring set is two " N " types symmetrical along axis.
It is additionally provided with guiding cone inclined-plane on described plug-in type pressure ring, inside the end face of described round buss, is correspondingly provided with guiding surface.
The annular of described upside plug-in type pressure ring is inserted internal side and is provided with wedge inclined-plane.
The annular of described downside plug-in type pressure ring is inserted external side and is provided with wedge inclined-plane.
Described clamp nut and plug-in type pressure ring center are provided with electric wire through-hole.
It is additionally provided with sealing gasket between described round buss end face and corresponding clamp nut.
Advantages of the present invention and effect: after the deformation of elastic packing ring set be face between electric wire and main casing round buss inwall and contact, greatly, waterproof sealing effect is reliable for contact area.The internal diameter size of elastic packing ring set is not limited by the diameter of wire, adapt to the electric wire of various outer diameter, when more rewiring, if the scope that electric wire can mate at elastic packing ring set, need not change arbitrary accessory of sealing device, reduce the complexity of design, make maintenance of equipment function admirable, minimizing use cost.
