[embodiment]

Please refer to Fig. 1 to shown in Figure 4, the utility model micro coaxial cable connector assembly 100 comprises insulating body 1, be contained in some conducting terminals 2 in insulating body 1, be assembled in insulating body 1 and be used for accepting the dividing plate 3 of conducting terminal 2, the cable 4 that is electrically connected with conducting terminal 2 and the cladding 6 that is coated on cable 4, conducting terminal 2 and dividing plate 3.

Insulating body 1 comprises the extension 12 that main part 11 and autonomous body 11 both sides, rear portion extend back and form.Be provided with some terminal containing slots 112 that run through main part 11 front and rear surfaces in main part 12, terminal containing slot 112 is divided into upper and lower two rows.Main part 11 rear surfaces are interval with row's blind hole 115 between two row's terminal end pilot trench 112.The upper and lower surface of main part 11 is respectively equipped with T-shape fin 113 and " one " type fin 114 that plays foolproof function when coordinating with butt connector, and a pair of protuberance 111.

Conducting terminal 2 is that metal material is stamped to form, comprise some single terminals 21 and four pairs of difference signal terminal 22, each conducting terminal 2 all comprises

holding section

201, and 201 extend forward and sweeping docking section 202 from the holding section, and is positioned at the afterbody 203 at rear portion, holding section.Some single terminals 21 comprise signal terminal and earth terminal.The autonomous body 201 of afterbody 203 of single terminal 21 straight line backward extends.The afterbody 203 of every pair of difference signal terminal 22 relatively bends and extends back itself and main part 201 are misplaced on fore-and-aft direction.Thereby the afterbody 203 of every pair of difference signal terminal 22 is mutually close.

Dividing plate 3 is to be made by insulating material, and it comprises base portion 30, and the hold-down arm 31 that arranges from some intervals that base portion 30 front surface mid portions extend forward offers opening in the middle of each hold-down arm 31 the hold-down arm front end is divided into two projections 310.The upper and lower surface of base portion 30 is respectively equipped with depressed part 303.Base portion 30 is provided with the some grooves 302 that are through to depressed part 303 from base portion 30 front surfaces.The up and down is respectively equipped with the jube 3031 at two intervals in depressed part 303, and base portion 30 rear surfaces depressions have a registration hole 304, and when external mold forming covered body 6, location hole 304 is full of plastic cement and can reliably be positioned in cladding 6.

Cable 4 comprises some solid conductors 40 and four differential pair wires 41.The heart yearn 401 that comprises conduction in each root solid conductor 40.Each root differential pair wire 41 comprises a pair of signal conductor 411 for the output difference sub-signal and an earth lead 412.In the present embodiment, differential pair wire 41 is Shielded Twisted Pair (STP, Shielded Twisted Pair), and a pair of signal conductor 411 and an earth lead 412 are coated by layer of metal paper tinsel (adopting aluminium foil) more.

During assembling, with conducting terminal 2 be divided into two rows and along from back to front direction insert the terminal containing slot 112 of insulating body 1 correspondence interior in, the afterbody 203 of conducting terminal 2 is exposed to outside insulating body 1.Dividing plate 3 is assembled in insulating body 1 rear portion from back to front, the extension 12 of insulating body 1 both sides is limited to dividing plate 3 wherein, dividing plate 3 installation portions 31 insert in the blind hole 115 at insulating body 1 rear portion, and the projection 301 of dividing plate 3 both sides slips in the guidance part 116 of insulating body 1 both sides and makes dividing plate 3 be positioned insulating body 1.The afterbody 303 of conducting terminal 2 passes the groove 302 of dividing plate 3 and extends bottom surface as for the depressed part up and down 303 of dividing plate 3, the every pair of difference signal terminal to 22 afterbody 203 by jube 3031 intervals.Solid conductor 40 and differential pair wire 41 are welded in the afterbody 203 of conducting terminal 2.Every differential pair wire 41 interior a pair of signal conductors 411 are welded in the afterbody 203 of difference signal terminal 22.Two pairs of differential pair wire 41 interior earth connections 411 all are welded in the afterbody 203 of a single earth terminal 21 between two pairs of differential pair wires 41.Distance after the distance of the nature between the exposed portions serve of differential pair wire 41 after peeling off aluminium foil bends with the afterbody of every pair of difference signal terminal 22 203 approaches.With insulating body 1, dividing plate 3 is coated in cladding 6 at last.

Spacing between signal conductor 411 in the present embodiment in the every pair of differential pair wire 41 approaches the distance between every pair of difference signal terminal 22 afterbodys 203 after bending, and the effect that reaches when both are equal is better.

Cable connector combination 100 of the present invention, because difference signal terminal is also mutually close to 22 the relative bending of afterbody 303, thereby less with the differential pair wire 41 strip off aluminium foils of a pair of differential signal end 22 welding, open distance less, again the two-terminal in a pair of difference signal terminal 22 is separated with jube 3031, thereby can effectively prevent change in the instantaneous impedance and cross-talk.
