Description
Technical field
The present invention relates to a kind of sealing configuration, relate to a kind of electric device cable outlet hole sealing configuration specifically.
Background technique
Be arranged on outdoor electric device, the electrical signal that its internal circuit and element produce will be exported by the elastic cable paper with screen layer, and elastic cable paper is drawn by the outlet aperture on electric device housing.Because the Environmental Conditions condition of electric device is more severe, wet by the rain and burnt by the sun, cable outlet place easily intakes and is subject to the dipping of ponding, thus damage inner circuit electrical element, cause electric device to lose function or reduce its service precision, affecting its working life and life cycle, existing encapsulating method all can not reach the sealing effect of sealing structure, can not meet some needs to the higher electric device of seal request, the problems referred to above are badly in need of improving.
Summary of the invention
The object of this invention is to provide a kind of electric device cable outlet hole sealing configuration, solve cable outlet place sealing effect not good, easy water inlet and be subject to the dipping of ponding, thus damage electric elements inside, cause electric device to lose function or reduce the problem of its service precision.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The invention provides a kind of electric device cable outlet hole sealing configuration, this cable outlet hole sealing configuration comprises the insulating washer with several apertures, with the cable lug rubber guard post of several apertures, the round-meshed special-shaped metal trim ring of several Intermediate Grays, the round-meshed shaped rubber seal ring of several Intermediate Grays, the round-meshed compression spring of several Intermediate Grays and the round-meshed hollow compression plug of Intermediate Gray, the above-mentioned parts order be arranged in electric device wire outlet hole is first electric device inner lead is passed insulating washer by the aperture in insulating washer, cable lug rubber guard post is passed again by the aperture in cable lug rubber guard post, then by hollow compression plug, compression spring, special-shaped metal trim ring and shaped rubber seal ring are set on multi-core cable wire one by one, wherein special-shaped metal trim ring, shaped rubber seal ring intersects and loads in electric device wire outlet hole and occur in pairs, compression spring is also occur also that the mode of withholding is set on shielded multiconductor cable line mutually in pairs, then connect each for elastic cable paper line with electric device inner lead formation terminal respectively, and make each terminal all be in each string holes of cable lug rubber guard post, form " string-like " connecting body, finally again " string-like " connecting body is slowly pushed in the cable outlet hole of electric device, and to be threaded with electric device aperture with screwed hollow compression plug and to tighten, thus compress each part, shaped rubber seal ring is made to produce elasticity extruding, inside contract outer rising, make hole internal pore asphyxia by external pressure on the chest and abdomen, reach sealing.
Further improvement of the present invention is: this cable outlet hole sealing configuration also comprises an Intermediate Gray round-meshed elastic cable paper screen layer metal platen, the above-mentioned parts order be arranged in electric device wire outlet hole is first electric device inner lead is passed insulating washer by the aperture in insulating washer, cable lug rubber guard post is passed again by the aperture in cable lug rubber guard post, then by hollow compression plug, compression spring, special-shaped metal trim ring, shaped rubber seal ring and elastic cable paper screen layer metal platen are set on shielded multiconductor cable line one by one, elastic cable paper screen layer is stripped out simultaneously, and be pressed between elastic cable paper screen layer metal platen and a special-shaped metal trim ring bottom, then connect each for elastic cable paper heart yearn with electric device inner lead formation terminal respectively, and make each terminal all be in each string holes of cable lug rubber guard post, form " string-like " connecting overall, finally more above-mentioned " string-like " connecting body is slowly pushed in the cable outlet hole of electric device, and to be threaded with electric device aperture with screwed hollow compression plug and to tighten, thus compress each part, shaped rubber seal ring is made to produce elasticity extruding, inside contract outer rising, make hole internal pore asphyxia by external pressure on the chest and abdomen, reach sealing.
Further improvement of the present invention is: compression spring is bowl-type.
Further improvement of the present invention is: the number of special-shaped metal trim ring, shaped rubber seal ring and compression spring is determined by the length of electric device wire outlet hole and seal degree.
Beneficial effect of the present invention: in sealing structure, shaped rubber seal ring directly produces seal action, hollow compression plug, compression spring and special-shaped metal trim ring are to having sealed indirectly-acting, namely produce and transmit extruding force, make rubber ring jam-packed closely knit, insulating washer mainly plays thrust function and insulating effect, elastic cable paper screen layer metal platen is the screen layer compressing elastic cable paper, do not play insulating effect, cable lug rubber guard post is the jointing between protection electric device internal cable and extraction cable, insulation is closed to make it, also play part seal action simultaneously.By shaped rubber seal ring by jam-packed, substantially increase seal degree, generally, electric device inside can not be entered by the immersion of this seal arrangement, this ensures that there electric device in the presence of a harsh environment can reliably, stable to use, long period of soaking all can not be intake, and sealing effect is that general sealing configuration and sealer are incomparable.
Novel structure of the present invention, practical reliable, prevent cable outlet place easily intake and damage electric elements inside, cause electric device to lose function or the situation that reduces its service precision occurs, waterproofing effect is splendid.
