Property sealing ring 5 internal diameter of the outer diameter with 23 inlet of jack match, be less than chamber at a distance from elastic seal ring 5 to 13 end of contact pin
The bottom of body 26 could make elastic seal ring 5 that can rise after plug 1 is inserted into sleeve 2 in this way to the distance of 2 end of sleeve
To the effect of sealing.Due to that could rotate after still needing to push plug 1 after raised line 14 is entirely through through slot 25, and reach locating slot
Plug 1 can spring back a small distance after unclamping when 28 position, if not set elastic seal ring 5, interface blow-by, just have
The risk that dust, steam enter.Elastic seal ring 5 in the present embodiment is rubber seal.
The use process of the connector of quick detachable photovoltaic junction box in the present embodiment described briefly below:
The initial position of the initial position of raised line 14 and through slot 25 is opposite in 180 °, when specifically used, the first step, need to first by
Plug 1 rotates clockwise 180 °, the raised line 14 on plug 1 is directed at 25 position of through slot, as shown in fig. 7, arrow is in figure
The direction of rotation of plug 1；Plug 1 is inserted into sleeve 2 by second step, as shown in figure 8, arrow is the insertion side of plug 1 in figure
To；Third step, after raised line 14 is passed through from through slot 25 completely, elastic component 27 is in compressive state, at this time that plug 1 is counterclockwise
180 ° of resets are rotated, as shown in figure 9, arrow is the direction of rotation of plug 1 in figure.So that the generation of raised line 14 and through slot 25 is wrong
Position, after release after plug 1, due to the elastic force that elastic component 27 provides, raised line 14 is caught in locating slot 28, achieve the effect that it is fixed,
Stability is further increased, prevents from loosening or falling off between plug and sleeve.
When disassembly, it is only necessary to press plug 1, raised line 14 is made to rotate raised line 14 counterclockwise to through slot after being detached from locating slot 28
25 position, can pull the plug out of the socket 1 under the action of elastic component 27, and disassembly easy to use is quick.
