Specific embodiment
It is practical below in conjunction with this in order to make those skilled in the art more fully understand the technical solution of the utility model Attached drawing in new embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that institute The embodiment of description is only the embodiment of the utility model a part, instead of all the embodiments.Based on the utility model In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts The range of the utility model protection all should belong in example.
Embodiment one
Referring to Fig.1-9, the connector of the quick detachable photovoltaic junction box of one kind of the present embodiment, including mutually matched plug 1 and sleeve 2, positive electrode 11 is provided in plug 1, negative electrode 21 is provided in sleeve 2, plug 1 includes header body 12 and sets The contact pin 13 in header body 12 is set, sleeve 2 includes sleeve ontology 22, offers on sleeve ontology 22 and matches with contact pin 13 Jack 23, there is in jack 23 the annular blend stop 24 matched with contact pin 13, have on the side wall of contact pin 13 and prolong with contact pin 13 The identical raised line 14 in direction is stretched, the through slot 25 matched with raised line 14, annular blend stop 24 and negative electricity are offered on annular blend stop 24 It is provided with cavity 26 between pole 21, elastic component 27 is provided in cavity 26, annular blend stop 24 is opened up close to the side of negative electrode 21 There is the locating slot 28 for accommodating raised line 14, and the width of locating slot 28 is slightly wider than the width of raised line 14.It is mutually matched by being arranged Plug 1 and sleeve 2 enable plug 1 to be very easily inserted into sleeve 2 or extract from sleeve 2, and in the contact pin of plug 1 Raised line 14 is set on 13, and setting and the mutually matched annular blend stop 24 of raised line 14, through slot 25 and elastic component 27, make in jack 23 Obtaining contact pin 13 can be fixed in sleeve 2;By being provided with locating slot 28 in sleeve 2, it is fixed to be stuck in raised line 14 In the slot 28 of position, the connective stability of plug 1 Yu sleeve 2 is further increased, prevents from loosening or falling off between plug 1 and sleeve 2.This The gripping notch for facilitating operator to hold is also provided in embodiment on sleeve 2.
Locating slot 28 and through slot 25 are located at the both ends of same diameter in jack 2, i.e., locating slot 28 and through slot 25 are in 180 ° of phases It is right.And the initial position of the initial position of raised line 14 and through slot 25 is in 180 °, when specifically used, needs first to revolve plug 1 clockwise Turn 180 °, i.e., raised line 14 it is corresponding with 25 position of through slot after, be inserted into, when raised line 14 will be inserted after passing through in through slot 25 completely First 1 180 ° of resets of rotation counterclockwise, finally unclamp plug 1, and elastic component 27 is sprung back, and raised line 14, which is caught in locating slot 28, springs back lock Tightly, such setting can cause photovoltaic module in permanent worker to avoid the stress that conducting wire is generated by rotation when connector interconnects Make to generate risk under state.
As Figure 4-Figure 6, since spring is cheap and easy to get and effect is good, the elastic component 27 in the present embodiment is spring, negative electricity Spring is run through in pole 21.
As shown in Figure 1-3, have on plug 1 and the side close to each other of sleeve 2 protrusion or recess for marking rotation The mark 3 in direction, initial position and final position, by setting mark 3, so that rotation has more purpose, rotation is convenient.This reality It applies in example and is provided with positioning protrusion 41 on the side of sleeve 2 in plug 1, sleeve 2 has and determined on the side of plug 1 The raised 41 mutually matched grooves 42 in position.By the way that mutually matched positioning protrusion 41 and groove 42 is arranged, so that rotation is more square Just.
There is in contact pin 13 close to one end of header body 12 elastic seal ring 5 for being used for sealing, and bullet in the present embodiment 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.
