Abstract
The utility model discloses a solar-energy alternating current connector with a stage-type sealing washer. The connector comprises a tensile device, a protective housing, a screw cap and the stage-type sealing washer, wherein the protective housing is internally provided with an annular boss for preventing the stage-type sealing washer from moving downwards, the annular boss is tightly connected with the stage bottom of the stage-type sealing washer, the upper part of the stage of the stage-type sealing washer is connected with the tensile device, and the highest face of the stage-type sealing washer is lower than that of tightening teeth of the tensile device. According to the connector provided by the utility model, the highest face of the stage-type sealing washer is lower than that of the tightening teeth, so the problem that the tightening teeth puncture through the sealing washer is avoided; the bottom of the washer completely fits a sealing washer support chamber at the inner side of the protective housing, the tensile device is mounted outside the stage-type sealing washer, and the screw cap is used for tightening, thereby enabling the sealing washer to better fit the sealing washer support chamber at the inner side of the protective housing; waterproofness can be carried out at the side wall and the bottom face, so waterproof paths are enlarged; and after the tensile device is stressed, the bottom of the tensile device presses the stage of the sealing washer, and because the sealing washer has the stress for resisting deformations, sealing becomes more tight and effective.
Description
Technical field
The utility model relates to solar energy and exchanges connector, is specifically related to a kind of solar energy with steps type seal packing ring and exchanges connector.
Background technology
Solar energy exchanges connector and is mainly used in photovoltaic DC-to-AC converter; electric energy will be exported to use just must have associated components as transport vehicle, and photovoltaic system is the interface unit that plays transmission current, safeguard protection effect between inverter and load device with interchange connector.Solar energy connector needs outer protection shell to prevent the destructions of external material to solar energy connector such as dust and aqueous vapor.While containment vessel inside need to be added seal washer and be prevented that aqueous vapor intrusion sun connector is inner.Traditional seal washer is straight barrel type (as depicted in figs. 1 and 2), plays the just sidewall of seal washer of sealing effectiveness, and sealed pathway is shorter.Therefore when straight tube seal washer tightens up tooth and screws higher than tension device, when tension is partly tightened up and is shunk in teeth directional, the seal washer body that will certainly bite, thus reduce its sealing property and useful life.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of solar energy with steps type seal packing ring to exchange connector.
The utility model is to realize by following technical scheme: a kind of solar energy with steps type seal packing ring exchanges connector, comprise tension device, containment vessel, nut, steps type seal packing ring, described containment vessel inside is provided with the annular projection for stopping that steps type seal circle moves downward, the step bottom of the tight connected unit step seal of described annular projection packing ring, the step top of described steps type seal packing ring connects tension device, the highest of described steps type seal packing ring is tightened up the highest of tooth lower than tension device, described tension device tightens up tooth by several and is circle-shaped and combines.
As such scheme preferably, it is triangle, rectangle or trapezoidal lower anti-slop serrations that the top of the screw thread of the afterbody of described containment vessel is provided with profile of tooth, the bottom of described tension device be provided with the upper anti-slop serrations being meshed with anti-slop serrations.
The top of tightening up tooth wherein, is reverse-hook shape.
The utility model has the advantage of: in the utility model, the highest of the seal washer of step has avoided tightening up lower than tightening up the highest face of tooth the problem that tooth punctures sealing ring.The seal washer design of step is fitted packing ring bottom and containment vessel inner seal packing ring support cavity completely; tension device in the seal washer external mounting of step, then tighten up and make seal washer secure fit containment vessel inner seal packing ring support cavity more by nut.Therefore can be in the dual waterproof of sidewall and bottom surface, anti-water route strengthens, and meanwhile, after tension device is stressed, press seal packing ring step place, bottom, because seal washer has the stress of self resistance to deformation, compacts sealing, effectively more.Also change the smooth structure of traditional integral type; the main part that solar energy is exchanged to connector is divided into containment vessel and tension device; the tailing screw flight top of containment vessel and tension device bottom design the anti-slop serrations structure of can intermeshing; coordinate anti-loosening tooth; when nut screws in; tension device tightens up the power that tooth only has inside contraction; and tension device body can not produce rotation in a circumferential direction; and then tightening force is larger, coordinates tension device can realize self locking functions and make the cable part difficult drop-off that is connected with terminal.
