Description
Technical field
The present invention relates to a kind of electric connector, especially a kind of electrical connection that is used for lead-in wire such as the cable or the similar electric wire of solar photovoltaic assembly is to the improvement of existing solar photovoltaic assembly with electric connector structure, belongs to the electroporation field
Background technology
Adopt electric connector to realize the quick connection of battery lead in
solar photovoltaic assembly.But the electric connector structure in the prior art is complicated, assembling is taken a lot of work, cost is high, and because complex structure causes the part of connector many again, the working of plastics wall is thin, and mechanical strength is relatively low.At present, solar photovoltaic assembly common on the market is to lean on nut shaft to produce displacement to rotation with electric connector, compresses interior pawl by inwall, compresses sealing ring through interior pawl component again, and the distortion by sealing ring at last compresses cable.Said structure mainly leans on the distortion of sealing ring, makes between cable and pedestal tightly to touch, thereby plays sealing function; In addition, lean on the distortion of sealing ring equally, make between cable and pedestal and tightly locate, thereby guarantee that the axial tension of cable reaches the moment of regulation.The defective of its existence is: at first, this structure mainly leans on the mechanical strength of nut to guarantee above performance, and most of in the market nut all is to adopt engineering plastics; Polyamide nylon PA66 particularly; These type of engineering plastics can't guarantee the weatherability more than 10 years under present technical conditions, be easy to generate distortion, cracking along with plastic ageing; Thereby make the disabler of nut, the consequence of bringing is the damage of whole connector; Secondly; Because solar photovoltaic assembly in outdoor application, often meets with wind and weather, wherein connector is under the blowing of wind-force; Cable on it is easy to generate friction and damages the cable protection skin at the place, contact site with nut, influence the useful life of connector equally.
To existing solar photovoltaic assembly with the connection compactness, sealing and the fastness that exist in the electric connector poor and cable is easy to wear and be not durable, problem such as useful life is short; The applicant has passed through useful exploration; Found the way of dealing with problems, the technical scheme that will introduce below produces under this background
Summary of the invention
task of the present invention be to provide a kind of can guarantee between cable and the pedestal be connected reliable and sealing and firmly excellent performance, cable is durable and the solar photovoltaic assembly of the architecture advances of long service life is used electric connector.
task of the present invention is accomplished like this; A kind of solar photovoltaic assembly is used electric connector; Be characterized in: it comprises sleeve seat, lock pin seat, first nut, second nut, first cable, second cable, first cable protective kit, second cable protective kit, the anti-skidding hoop of first metal and the anti-skidding hoop of second metal; Be arranged with the anti-skidding hoop of one first metal on the outer wall of described first cable; The end integrated injection molding of first cable outside the anti-skidding hoop of said first metal has a sleeve seat; Narrow the contracting in front end end of said sleeve seat and the both sides, middle part that are formed with sleeve, sleeve seat length direction are formed with respectively on the outer wall of end, rear end of a lock hook, sleeve seat and are formed with first screwed plug; In described sleeve, be inserted with a lock pin cover, described lock pin cover is realized being electrically connected with the lead in first cable; Be arranged with the anti-skidding hoop of one second metal on the outer wall of described second cable; The end integrated injection molding of second cable outside the anti-skidding hoop of said second metal has a lock pin seat; The both sides that the axial centre of said lock pin seat is formed with the leading section of the sleeve hole that is used to supply the sleeve inserting, lock pin seat are formed with respectively on the outer wall of rearward end of the lock hook hole that is used for cooperating with lock hook and lock hook groove, lock pin seat and are formed with second screwed plug; In described sleeve hole, be inserted with one and be used for realizing with the inserting of lock pin cover the lock pin that is electrically connected, described lock pin is electrically connected with lead realization in second cable; Described first cable protective kit is set in the end, rear end of first cable, is formed with first sealing flange at first cable protective kit towards an end end of sleeve seat; Described first spiro cap is located on first cable and revolves and join with first screwed plug on the sleeve seat, and first sealing flange that first cable protective is put places to be realized in the inner volume of said first nut fixing first cable protective kit and sleeve seat being connected between the two; Described second cable protective kit is set in the end, rear end of second cable, is formed with second sealing flange at second cable protective kit towards an end end of lock pin seat; Described second spiro cap is located on second cable and revolves and join with second screwed plug on the lock pin seat, and second sealing flange that second cable protective is put places to be realized in the inner volume of said second nut fixing second cable protective kit and lock pin seat being connected between the two.
in a specific embodiment of the present invention, described first cable protective puts to be provided with and is used for realizing friction tight first expansion slot with the outer wall of first cable.
in another specific embodiment of the present invention, described second cable protective puts to be provided with and is used for realizing friction tight second expansion slot with the outer wall of second cable.
In another specific embodiment of the present invention, described sleeve seat is arranged with a sealing ring being close on the end of sleeve
.
The present invention is because after adopting said structure; One of advantage that has, owing on the outer wall of first cable, second cable, be arranged with the anti-skidding hoop of first metal, the anti-skidding hoop of second metal respectively; And then on first cable outside the anti-skidding hoop of first metal, the anti-skidding hoop of second metal, second cable respectively injection mo(u)lding sleeve seat, lock pin seat are arranged; This structure can make the axial tension of cable strengthen greatly on the one hand, on the other hand, because the anti-skidding hoop of metal has made cable produce the distortion to heart before injection moulding; Can not influence the distortion of moulding inside cable when the cable of connector afterbody twists after injection moulding yet; Thereby the sealing of connector and firm performance are greatly improved, on the one hand, when injection mo(u)lding, advance cast gate and just be aligned in the anti-skidding hoop of metal place again; The plastic liquid of its high temperature and high speed directly impacts on the anti-skidding hoop of metal, thereby can protect cable not sustain damage; Advantage two,
are owing to have additional first cable protective kit, second cable protective kit respectively on the outer wall of first cable, second cable; And be separately fixed at the afterbody of connector through first nut, second nut; This structure is leaned on the distortion of first cable protective kit, second cable protective kit on the one hand; Can further increase the sealing property of connector; Also solve connector on the other hand and under outdoor harsh climate environment, can protect cable injury-free, effectively prolonged the useful life of connector.
