Embodiment:
Please refer to accompanying drawing, wherein same label is represented corresponding or same assembly among the Ge Tu, and Fig. 2, Fig. 3 show profile, the three-dimensional exploded view of the utility model ground connection electric connector.Ground connection electric connector 20 comprises inner sleeve 21, outer sleeve 30, nut 40, reaches C shape contact spring 50.
This inner sleeve 21 has a hole 22, can be in order to admit the inner wire 61 and the insulator 62 (as Fig. 4 B) of coaxial cable 60.Inner sleeve 21 has outward flange 23, interface portion 24, tapered portion 25, and rear end extension 26, and this outward flange 23 is arranged at the front end of inner sleeve 21, and this tapered portion 25 is positioned at 24 of outward flange 23 and interface portion.
This outer sleeve 30 has inward flange 31, reaches rear end extension 32, this inward flange 31 is looped around on the interface portion 24, this rear end extension 32 forms concentric ring around relation with the rear end extension 26 of inner sleeve 21, the centre of this outer sleeve 30 then is that ring-type is hollow 33, can be in order to admit the outer conductor 63 and the crust 64 (as Fig. 4 B) of coaxial cable 60.
40 front ends at ground connection electric connector 20 of this nut, this nut 40 comprise annular end 41, hexagonal body 42, reach inward flange 43, and this inward flange 43 is at the terminal of nut 40 and can the revolution mode being arranged on outside the tapered portion 25 of inner sleeve 21.The inside of annular end 41 has screwed hole 44, and nut 40 is locked on the electronic installation 70 of hickey connector 71, make its mechanically with electric on become one (as Fig. 4 C).This inward flange 43 defines bellmouth 45 can be along tapered portion 25 upper and lower displacements of inner sleeve 21.
This C shape contact spring 50 is disposed at tapered portion 25 surrounding edges of inner sleeve 21 and keeps well with the inward flange 43 of nut 40 and contacts, by this can be effectively and guarantee that for a long time inner sleeve 21 forms ground connection with nut 40 and contact, and with the acquisition excellent electric characteristics.
Because this C shape contact spring 50 can keep in touch at the tapered portion 25 surrounding edge upper and lower displacements and the nut 40 of inner sleeve 21, so, nut 40 and hickey connector 71 are under sealed or not sealed fully situation, can utilize 50 upper and lower displacements of C shape contact spring to change, inner sleeve 21 and nut 40 be kept in touch obtain good ground connection property.
Fig. 4 A to Fig. 4 C shows that the utility model ground connection electric connector 20 locks in the step of electronic installation 70, before installation, the free end of this coaxial cable 60 must be removed crust 64 partly and the outer conductor 63 that turns back to expose insulator 62 and inner wire 61, after the free end of cable 60 is ready to, the free end of cable 60 is inserted in the ground connection electric connector 20, during insertion, the rear end extension 26 of inner sleeve 21 is forced between the insulator 62 and outer conductor 63 of cable 60.After cable 60 and ground connection electric connector 20 link, utilize this ground connection electric connector 20 to make coaxial cable 60 and electronic installation 70 interconnection, shown in Fig. 4 A.
Rotate this nut 40 and make hickey connector 71 be screwed together in the screwed hole 44 of annular end 41, shown in Fig. 4 B.During the rotation, C shape contact spring 50 be subjected to inward flange 43 promotion and to top offset, till nut 40 is tightly locked with interface connector 71 fully, at this moment, C shape contact spring 50 moves to upper end position from the lower end position of tapered portion 25, and the position contacts 40 maintenances of inner sleeve 21 and nut ground connection, shown in Fig. 4 C 43 of outward flange 23 and inward flanges.
As shown in Figure 5, when 71 of nut 40 and hickey connectors unclamp (locking) because of environmental factor or external factor, at this moment, this C shape contact spring 50 will move down along with the displacement of nut 40, so no matter nut 40 and 71 of hickey connectors are sealed or releasing orientation fully, the upper and lower displacement of this C shape contact spring 50 changes, inner sleeve 21 and nut 40 are kept in touch, and obtain good ground connection contact, to guarantee signal information transfer quality and excellent electric characteristics.
Although embodiment of the present utility model is detailed illustration, for the personage who is familiar with this technology, other the various changes that can associate easily or revise neither disengaging spirit of the present utility model and scope.Therefore in following claim, its for the narration containing all changes and correction and do all in scope of the present utility model.
