Embodiment:
Referring to Fig. 2, Fig. 3, show three-dimensional part sectional drawing, the cut-away view of the utility model coaxial cable connector.This coaxial cable connector 20 comprises that a coaxial inner and outer sleeves of radially being separated by 21,26 admits a coaxial cable with coaxial manner; An and conductive earthing spring 30.The front end of this inner sleeve 21 has an outward flange 22, one first interface portion 23, one second interface portion 24, and a rear end extension 25, and the external diameter of rear end extension 25 and wall ratio second interface portion 24 are little.The front end of outer sleeve 26 has an outer sleeve body 27 and a rear end extension 28, this outer sleeve body 27 is looped around on second interface portion 24 of inner sleeve 21, the external diameter of rear end extension 28 and wall ratio outer sleeve body 27 are little, and and the rear end extension 25 of inner sleeve 21 form concentric rings around relation, the centre then is that ring-type is hollow.Front end at coaxial cable connector 20 has a nut 29, its end is an inward flange 291, this inward flange 291 is clipped between outward flange 22 and the outer sleeve body 27, and can rotate freely 21,26 of inner and outer sleeves, the inside of nut 29 all is screw thread 292, and the outside is a hexagonal portion, and available spanner or other instrument are locked in connector on the electronic installation.
As Fig. 4 and shown in Figure 5, this conductive earthing spring 30 comprises ring part 31 in, and ring part 31 has a hole 32 in this, and first interface portion, 23 surrounding edges that its diameter can make spring 30 be configured in inner sleeve 21 become hesive combination.Conductive earthing spring 30 more comprises the edge of the elasticity alar part 33 of several slabbings with ring part 31 in uniformly-spaced being formed on.This elasticity alar part 33 from interior ring part 31 neck-outs and open a predetermined angular and the inward flange 291 of nut 29 do machinery and electric on combine (as Fig. 3), provide reliably at nut 29 and 40 of electronic installations by this to be electrically connected, to guarantee signal information transfer quality and excellent electric characteristics.
This conductive earthing spring 30 more comprises the outer arch portion 34 of several slabbings, and this outer arch portion 34 is integrally formed with interior ring part 31, and each outer arch portion is between two adjacent elasticity alar parts 33.Should closely contact with first interface portion, 23 surrounding edges by outer arch portion 34, can make 21 of conductive earthing spring 30 and inner sleeves become firm combining like this.
Referring to Fig. 6 and Fig. 7, show and coaxial cable connector 20 is installed in the step of electronic installation 40.At first, coaxial cable connector 20 is locked on the electronic installation 40, at this moment, this nut 29 fails to combine with hickey connector 41 fully, and this coaxial cable connector 20 guarantees its good metal contacting metal by the elasticity alar part 33 of conductive earthing spring 30 21 of nut 29 and inner sleeves.In fact, this elasticity alar part 33 outwards opens a predetermined angular and contacts with the inward flange 291 of nut 29, provides reliably at nut 29 and 40 of electronic installations by this to be electrically connected, as shown in Figure 6.
Then nut 29 is locked in fully on the hickey connector 41 of electronic installation 40, make the outward flange 22 of this inner sleeve 21 contact with the inward flange 291 of nut 29, during sealed, the elasticity alar part 33 of this conductive earthing spring 30 is compressed into the make position (see figure 7) from the deployed position (see figure 6), last binding site will make 33 of elasticity alar parts 23 of first interface portion of the inward flange 291 of nut 29 and inner sleeve 21, provide at nut 29 and 21 of inner sleeves by this to be electrically connected.
