Embodiment

Below will combine each execution mode shown in the drawings that the utility model is described in detail.But these execution modes do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these execution modes, method or the function all is included in the protection range of the utility model.

Shown in Fig. 1, the utility model photovoltaic connector 100 comprises public affairs slotting 10 and the mother slotting 20 who joins mutually with public affairs slotting 10.

Like Fig. 2 and shown in Figure 4, public slotting 10 comprise insulation shell 11, collar 12, sleeve 13, plug 14, interior pawl 15 and back cover 16.Insulation shell 11 comprises the insertion section 112 that main part 111 and autonomous body 111 1 ends extend forward, and the periphery of insertion section 112 is provided with the outstanding button gripping arm 113 of autonomous agent portion, and the end of button gripping arm 113 is provided with grab 114.The inside of insertion section 112 has container cavity 115, and this container cavity 115 runs through main part 111 backward and forms seal 116 in the other end of main part 111.Collar 12 at first gets into and is positioned to insert sleeve 13 then in the container cavity 115 along seal 116, sleeve 13 comprise 131, the first junction surfaces, columned first junction surface, 131 back end peripheries be provided with hangnail 132 with collar 12 clampings.Plug 14 is processed by elastomeric material, comprise the auxiliary section 141 of close encapsulation mouth 116 and supply in the socket part 142 of pawl 15 sockets.Plug 14 is corrosion-resistant and ageing-resistant, can prevent effectively that sealing gets into public 10 inside of inserting from seal 116.Interior pawl 15 is processed for flexible plastic material, has good toughness, the difficult fracture.Preferably, interior pawl adopts nylon PA66 material to process.Interior pawl 15 has radially outwards open some claws 151, U-shaped clamping part 133 clampings that cable (not shown) can get into container cavities 115 and had by sleeve 13 rear portions through interior pawl 15, plug 14.At last back cover 16 is connected with main part 111 through screw thread, back cover is in the process of being screwed into, thereby the claw of interior pawl 15 151 inwardly draws clamping cables in, prevents that it breaks away from photovoltaic connector because of external force.Because claw 151 has good toughness, in the gathering process, be difficult for fractureing, can well clamping cables.

Like Fig. 3 and shown in Figure 5, female slotting 20 comprise insulating body 21 and are contained in the contact pin 22 in the insulating body 21.The receiving space 213 that insulating body 21 comprises base portion 211, is positioned at the docking section 212 of base portion 211 1 ends and runs through base portion 211 and docking section 212.Base portion 211 is provided with groove 214 with docking section 212 joints, and the outside of groove 214 is provided with the stop part 215 that connects base portion 211 and docking section 212.Docking section 212 radially both sides is provided with the through hole 216 that interlocks and hold with public button gripping arm 113 of inserting on 10; Grab 114 on the button gripping arm 113 gets into groove 214 so that public affairs slotting 10 are inserted 20 lockings with mother; Stop part 215 is positioned at the outside of grab 114, can prevent the staff misoperation like this and push in opposite directions grab 114 cause public insert 10 with female 20 accidental of inserting.Open when needs and public to insert 10 with female when inserting 20, the space that can only use specific purpose tool to stretch between grab 114 and the stop part 215 can be opened both.In addition, the docking port 217 that supplies insertion section 112 to insert in the docking section 212 is set to the shape that cambered surface combines with the plane, can play the effect of anti-mis-insertion.Have only the external shape and the docking port 217 of insertion section 112 to coincide and to insert.At this moment, sleeve 13 contacts with contact pin 22 with realization and electrically conducts.Public slotting 10 are socketed with waterproof ring 17 in the rear end of insertion section 112 gets in female receiving space 213 of slotting 20 to prevent water.Female structure of inserting 20 base portions 211 roughly the same with public structure of inserting 10 main parts 111 and female insert 20 also be provided with collar, plug, interior pawl and back cover these with the public 10 identical parts of inserting, connected mode and effect are narrated in front accordingly, repeat no more at this.Contact pin 22 has columned second junction surface 221 because the diameter at second junction surface 221 is less than the diameter at first junction surface 131, public insert 10 with female insert 20 fasten after, first junction surface 131 will be socketed on second junction surface 221 to realize electrical contact.

The utility model photovoltaic connector public affairs are plugged the button gripping arm that is provided with and are plugged the through hole that is provided with and be interlocked with female, and simultaneously, the public sleeve that has of inserting is socketed in that female to insert the contact pin that has outside, can guarantee public inserting and female stable signal transmission of inserting.

Be to be understood that; Though this specification is described according to execution mode; But be not that each execution mode only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, and those skilled in the art should make specification as a whole; Technical scheme in each execution mode also can form other execution modes that it will be appreciated by those skilled in the art that through appropriate combination.

The listed a series of detailed description of preceding text only is specifying to the feasibility execution mode of the utility model; They are not the protection range in order to restriction the utility model, allly do not break away from equivalent execution mode or the change that the utility model skill spirit done and all should be included within the protection range of the utility model.
