Embodiment, belong to the scope of protection of the invention.
As shown in Fig. 1 ~ 7, applied to the locking device of photovoltaic connector, including the rotation at connector both ends is individually fixed in
Closing piece 1 and guide pad 2, wherein, fluted 3 are set on connector one end outer wall of fixed rotation closing piece 1, groove 3 is away from guiding
The side of block 2 is provided with first boss 31, and rotation closing piece 1 rotates coaxially with the periphery of first boss 31 to be connected, first boss 31 with it is recessed
Closing pieces 1 are circumferential to be uniformly distributed the one end of shell fragment 32 and is connected the side wall that groove 3 connects along rotating with six, the other end of shell fragment 32 and along groove
3 ring bodies 33 slided connect；Wherein, rotation closing piece 1 is provided with the first convex edge 11, and the first convex edge 11, which is enclosed, to be set as being used to supply guide pad
First cavitys 12 of 2 insertions, are provided with two special-shaped guide grooves on the inwall of the first cavity 12, in order that the stress of closing piece 1 must be rotated
Uniformly, two special-shaped guide grooves 13 are uniformly distributed along rotation closing piece 1 is circumferential, are additionally provided with the inwall of the first cavity 12 and shell fragment 32
Quantity is equal and angle corresponding to some L-type dead bolts 14；Guide pad 2 is fixed on the other end of connector, and its edge is provided with
Two convex edges 21, the bottom of the second cavity 22 that the second convex edge 21 is surrounded are provided with during it is close to rotation closing piece 1 to ring
The step surface 23 that body 33 is extruded, the edge of the second convex edge 21 are provided with six U corresponding to and angle equal with the quantity of shell fragment 32
Type groove mouth 24, two projections 25 slided along special-shaped guide groove 13 are additionally provided with the outer circumference surface of guide pad 2.
Above-mentioned guide pad 2 to rotation closing piece 1 close to during, guide pad 2 by ring body 33 to shell fragment 32 one
End is extruded, the other end fixed setting of shell fragment 32, therefore shell fragment 32 forms domes, and the height at the top of it gradually increases
Add, during the two is close to each other, projection 25 slides along special-shaped guide groove 13, and guide pad 2 itself does not rotate, when
During projection 25 is extruded special-shaped guide groove 13, rotation closing piece 1 rotates, and works as shell fragment by said structure
When 32 formation domes highly peak, L-type dead bolt 14 is just rotated to shell fragment 32 to be exceeded by U type slot 24
In the ring body of the periphery of guide pad 2, i.e., L-type dead bolt 14 is inserted in shell fragment 32, so that rotation closing piece 1 and guide pad 2 are vertically
It is fixed, using this structure, as long as ensureing that rotation closing piece 1 does not relatively rotate with guide pad 2, you can effective guarantee connection
Reliability, and the deformation of shell fragment 32 effectively alleviates the power being attached to the two in the process, avoids connector
Damage, in the present embodiment, in order to ensure rotation closing piece 1 does not relatively rotate with guide pad 2, be provided with rotation closing piece 1
Locking device 4, locking device 4 is the bolt with the screwed hole rotation connection on the first convex edge 11, after connecting in place, rotation
Tight bolt, you can so that bolt extrudes closing piece 1 is rotated tightly, and when connector is taken apart with guide pad 2, bolt need to only be revolved
Turn to loosen, and be firmly directed to extract in the spinning closing piece 1 of block 2.
In the present embodiment, rotation closing piece 1 on the end face 15 of connector contact with being provided with sealing structure, for ensureing to rotate
Do not enter dust at the rotation connection of closing piece 1, so as to ensure the fluency rotated.
Because the structure of projection 25 is relatively simple, in order to prevent it, stress is excessive and cause to damage in use,
The distance at the edge of the convex edge of projection 25 to the second 21 meets following condition, when the second convex edge 21 moves to and the phase of the first cavity 12
To when, projection 25 does not reach the special-shaped innermost end of guide groove 13, meets above-mentioned condition, you can so that projection 25 will not be in the mistake of locking
Hit in journey by the special-shaped innermost end of guide groove 13, avoid damaging.
The announcement and teaching of book according to the above description, those skilled in the art in the invention can also be to above-mentioned embodiment party
Formula is changed and changed.Therefore, the invention is not limited in embodiment disclosed and described above, to the present invention's
Some modifications and changes should also be as falling into the scope of the claims of the present invention.In addition, although used in this specification
Some specific terms, but these terms are merely for convenience of description, do not form any restrictions to the present invention, using with its
Same or analogous other systems, all fall in the scope of protection of the present invention.
