Background technology
The sealing nut that is used for the connection of solar module cable in the market exists many irrational places, what at first be that seal adopts is the cylinder of annular, the gap is bigger between assembling its inwall of back and the cable, behind nut screwing clamping, still have the gap between cable and the seal, thereby leave the into hidden danger of water humidity, on the other hand, the tightening device that sealing nut inside is used for cable is vertical long-armed, structure is comparatively hard, after the tightening device head tightened up, its end still left bigger gap, was difficult to make annular seal to reach desirable sealing effectiveness, very difficult and painstaking when causing operating personnel's fastening nut simultaneously, and anti-skidding line is only arranged on the outer peripheral face of nut, do not have and can be unfavorable for the outdoor study use for fastening of tool holding.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of favorable sealing property, installation and removal solar cell cable connection easily sealing nut is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of solar cell cable connects uses sealing nut, comprise and to be screwed at the nut body that has inner chamber in the nut butt joint, be provided with the rubber seal and the tightening ring of ring set on the rubber seal outer surface that can wear the photovoltaic cable in the inner chamber of described nut body, the inner chamber of nut body has conical section, tightening ring one end that is complementary with the conical section of nut body has outstanding sloping platform, be tightened in the process of nut butt joint at nut body, the outstanding sloping platform of the inclined-plane of described conical section compressing tightening ring is pressed on the leading section of rubber seal on the photovoltaic cable that wore thereby tightening ring produces radial contraction.
Specifically, the outstanding sloping platform of described tightening ring has and circumferentially is evenly equipped with the long-armed jaw oblique with respect to the tightening ring center, has the gap between the long-armed jaw, in the nut body rundown process, long-armed jaw end is oppressed on the inclined-plane of the conical section that the nut body inner chamber is had, long-armed jaw produces radial contraction and fills gap between the long-armed jaw, shrink the outer wall of the inner hole wall annular compressing rubber seal of the long-armed jaw that the back forms, on the photovoltaic cable that rubber seal is pressed on wore.
Further, the rearward end of described rubber seal has the sealing round platform, and in the nut body rundown process, the sealing round platform is pressed in the seal groove that has in the nut butt joint.
Manually tighten or the tool using clamping is tightened for convenient, on the outer surface of described nut body circumferentially five equilibrium be provided with the interior concave plane of at least 4 finger-like.
The beneficial effects of the utility model are: the utility model axially moves the oblique thrust that produces by nut body in rundown process, promote rubber seal and make radial contraction, thereby on the photovoltaic cable that rubber seal is pressed on wore, reached preferable sealing effectiveness, whole simultaneously installation connects also comparatively convenient and swift, be affectedly bashful the clamping when making things convenient for tool using again when circumferentially manual operations both had been convenient in the concave plane in the finger-like of five equilibrium setting on the outer surface of nut body.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of tightening ring described in the utility model.
Fig. 3 is the left view of Fig. 2.
Embodiment.
In conjunction with the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As Fig. 1～a kind of solar cell cable connection sealing nut shown in Figure 3, comprise and to be screwed at the nut body 1 that has inner chamber in the nut butt joint, be provided with the rubber seal 2 and the tightening ring 3 of ring set on rubber seal 2 outer surfaces that can wear the photovoltaic cable in the inner chamber of described nut body 1, the inner chamber of nut body 1 comprises thread segment 13 and conical section 11, tightening ring 3 one ends that are complementary with the conical section 11 of nut body 1 have outstanding sloping platform 31, described outstanding sloping platform 31 has and circumferentially is evenly equipped with 12 the long-armed jaws 32 oblique with respect to the tightening ring center, the gap that has certain tilted direction between per two long-armed jaws 32, be tightened in the nut butt joint process by its thread segment 13 at nut body 1, long-armed jaw 32 ends are oppressed on the inclined-plane of the conical section 11 that nut body 1 inner chamber has, make long-armed jaw 32 produce radial contraction and fill gap between the long-armed jaw 32, shrink the annular fully equably leading section outer wall of oppressing rubber seal 2 of inner hole wall of the long-armed jaw 32 of back formation, rubber seal 2 is pressed on the photovoltaic cable that wore, thus the sealing between realization caulking gum spare 2 and the photovoltaic cable.
Described rubber seal 2 has the endoporus that passes the photovoltaic cable, this endoporus has certain tapering, photovoltaic cable perforating position aperture is bigger, then slowly dwindle, until packing tightly the photovoltaic cable, the outer wall of rubber seal 2 is the face of cylinder with constant slope, match with the inwall of tightening ring 3, the rearward end of rubber seal 2 has sealing round platform 21, be tightened in the nut butt joint process at nut body 1, sealing round platform 21 is pressed in the seal groove that has in the nut butt joint, thereby realizes the sealing between rubber seal 2 and the nut butt joint.
