Description
Technical field
The present invention relates to photovoltaic accessory technical field, especially relate to a kind of connector of photovoltaic junction box.
Background technology
The connector of photovoltaic junction box must have nut.Operationally, after this nut screws, the claw on plastic cement sealing device (being called for short: the gaily decorated basket or Gland Cage) is compressed gradually, and then makes cable be able to stable connection.But, in actual use, the phenomenon that the nut tightened already is easy to occur reversing voluntarily and gets loose, and then the connection forming cable is unclamped.
Summary of the invention
The object of this invention is to provide a kind of connector of photovoltaic junction box, it has the advantages that its nut not easily gets loose voluntarily.
The technical solution adopted in the present invention is: the connector of photovoltaic junction box, comprise the negative or positive electrode plug on the box body for being connected to photovoltaic junction box, this plug left part has external screw thread, and this plug has the penetrating lumen pore in left and right, through there being cable in this lumen pore, simultaneously, sealing ring is provided with in this lumen pore, sealing snare is on this cable, and, on this cable, also cover has plastic tube and nut, the right-hand member of this plastic tube withstands on the left part of this plug, the left part of this plastic tube is circumferentially evenly distributed with multiple claw, this nut inner chamber is the bellmouth that the little right-hand member of left end is large, this bellmouth and this claw match, and the internal thread that inner chamber right part has and this external screw thread matches of this nut, the inner chamber left part inner surface of described nut is provided with the double wedge of the direction of rotation of incline direction when this nut advances.
The present invention is compared to the prior art advantageously: nut not easily gets loose voluntarily.The nut inside of the connector of photovoltaic junction box of the present invention has double wedge, when those double wedges make this nut precession, can not produce resistance; Otherwise once this nut is for reversion, then this double wedge can produce a reverse frictional force, effectively prevent getting loose voluntarily of this nut.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective exploded view of embodiments of the invention;
Fig. 2 is the front view (amplifying relative to Fig. 1) of plug of the present invention;
Fig. 3 is the schematic perspective view (amplifying relative to Fig. 1) of plastic tube of the present invention;
Fig. 4 is the schematic perspective view (amplifying relative to Fig. 1) of nut of the present invention.
In figure:
10, plug, 11, lumen pore, 12, external screw thread;
20, cable;
30, sealing ring;
40, nut, 41, double wedge;
50, plastic tube;
100, box body.
Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 4: the connector of photovoltaic junction box, comprises the negative or positive electrode plug 10 for being connected on the box body 100 of photovoltaic junction box.This plug 10 left part has external screw thread 12.And this plug 10 has the penetrating lumen pore in left and right 11, through there being cable 20 in this lumen pore 11.Meanwhile, be provided with sealing ring 30 in this lumen pore 11, sealing circle 30 is enclosed within this cable 20.That is, sealing circle 30 plays good waterproof effect.And also cover has plastic tube 50 and nut 40 on this cable 20.Concrete, at the beginning of installation, this nut 40 is positioned at the left of this plastic tube 50.After assembling, the right-hand member of this plastic tube 50 withstands on the left part of this plug 10.More specifically, the left part of this plastic tube 50 is circumferentially evenly distributed with multiple claw 51, this nut 40 inner chamber is the bellmouth (not shown on figure) that the little right-hand member of left end is large, this bellmouth and this claw 51 match, and the internal thread that the inner chamber right part of this nut 40 has and this external screw thread 12 matches (not shown on figure).That is, screwing gradually along with this nut 40, the oppressive force of this bellmouth to those claws 51 increases gradually, thus this cable 20 is packed tightly by those claws 51.Further say, the inner chamber left part inner surface of this nut 40 is provided with the double wedge 41 of the direction of rotation of incline direction when this nut 40 advances.That is, when advancing along this nut 40, direction of rotation when namely this nut 40 is tightened, the root of this double wedge 41 is positioned at the front of the end of this double wedge 41.Like this, when screwing this nut 40, this double wedge 41 can not produce any effect; Otherwise when this nut 40 is for reversion, this double wedge 41 meeting and this cable 20 or claw 51 interact and produce a reverse frictional force, effectively reduce the probability that this nut 40 gets loose.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
