Abstract
The utility model relates to a waterproof joint for a wire. The utility model aims to provide a waterproof joint used for a wire and having characteristics of excellent waterproof performance, normal use in regions with relatively great temperature differences and capabilities of ensuring water resistance and dryness of outdoor electrical products. The waterproof joint comprises an external thread connecting piece. A wire hole is arranged inside the external thread connecting piece. A hexagon is arranged in the middle of the external thread connecting piece. A funnel-shaped groove is arranged above the wire hole of the external thread connecting piece. A funnel-shaped sealing member is arranged inside the funnel-shaped groove. A wire through hole is arranged in the center of the funnel-shaped sealing member. The diameter size of the wire through hole matches the outer diameter size of the wire. The upper end of the external thread connecting piece is provided with a nut. An O-shaped groove is arranged on the lower part of the external thread connecting piece. An O-shaped sealing ring is arranged inside the O-shaped groove. The waterproof joint has excellent sealing performances and is suitably used in street lamps.
Description
Technical field
The utility model relates to a kind of water joint, in particular, relates to a kind of water joint that is applied to outdoor electric product.
Background technology
In the prior art, during out of doors application of electric product, when the moist operating mode that causes in rainy day, snow day and the various day and night temperature difference occurs, can cause product occur short circuit and, influence the useful life of product and cause security incident; This just requires product electric wire downlink connection hole in use that the better waterproof energy need be arranged, water joint is generally used in the electric wire gateway of electric product shell, the joint of producing on the current market is when connecting electric wire, though there is portioned product to use the structure of waterproof grommet, but, when practical application, because there is defective in its structure, waterproof construction is not tight, water resistance difference and can not adapt to bigger difference variation, aging easily, and then the useful life that causes having influence on owing to the water resistance of joint whole outdoor electric product.In the prior art, the water joint of electric product exists water resistance difference and the irrational technological deficiency of its waterproof construction, becomes those skilled in the art's technical problem anxious to be solved.
Summary of the invention
Technical purpose of the present utility model is to overcome power lug of the prior art to exist the water resistance difference and influence electric useful life and cause the technical problem of security incident easily; Provide a kind of water resistance splendid, can normally use in temperature difference larger area, to ensure the water joint that is used for electric wire of outdoor electric product waterproof drying.
For realizing above technical purpose, the technical solution of the utility model is:
Be used for the water joint of electric wire, include the external screw thread connector, be provided with wire hole in the described external screw thread connector, be provided with hexagon shape in the middle of the external screw thread connector; The wire hole top of external screw thread connector is provided with the infundibulate groove, is provided with the infundibulate seal in the described infundibulate groove, is provided with electric wire through-hole in the middle of the described infundibulate seal, and described electric wire through-hole diameter and electric wire external diameter size are complementary; External screw thread connector upper end is provided with nut; External screw thread connector below is provided with O shape groove, is provided with O-ring seals in the described O shape groove.
Further, described infundibulate seal is the inner silicone-rubber seals that is provided with the spring skeleton.
Further, be provided with internal thread in the described infundibulate groove, described infundibulate seal is provided with the external screw thread that matches with internal thread.
In application of the present utility model, adopted two-layer hermetically-sealed construction, the lower end of threaded connector outside, O-ring seals is with tight seal between the perforate of electrical enclosure and the external screw thread connector, electric wire passes in the middle electric wire through-hole of infundibulate seal, when nut is screwed down when pressing down, the peripheral structure pressurized of infundibulate seal, form the pressure of an ecto-entad, compress sealing with passing the middle electric wire of infundibulate seal, moisture content can't be entered in the electrical enclosure by electric wire, has adopted the silicone-rubber seals that has the spring skeleton, has more elasticity and can be fit to normally to use in cold or the hot weather.
Useful technique effect of the present utility model is: sealing property is splendid, has prolonged the useful life of outdoor electric product, and can normally use in severe cold or hot weather, is suitable for using in street lamp, solar cell or the electric cabinet.
