[embodiment]

Please referring to figs. 1 through Fig. 4, micro coaxial cable connector assembly 100 of the present invention comprises insulating body 1, be contained in plurality of conductive terminals 2 in the insulating body 1, be assembled in insulating body 1 rear end printed circuit board (PCB) 3, be provided with the cable 4 of some leads (not shown) and braid (not shown), metal shell 5, stress relief element 6 and the ground loop 7 of coated insulation body 1.

Insulating body 1 front end is enclosed to form a trapezoidal grafting space 11 to accommodate butt connector (not shown) by wall.The last lower wall of insulating body 1 is provided with plurality of terminals groove 12, and is connected with grafting space 11, in order to accommodate conducting terminal 2.Each conducting terminal 2 is inserted into front end along terminal groove 12 from the rear end of the body 1 that insulate, and inwardly stretches to grafting space 11 in order to electrically to contact with butt connector.Insulating body 1 also comprises body 14, the extension 15 that extends back from body 14 and a pair of grab 16 that is positioned at extension 15 rear ends.Form a step 13 between body 14 and the extension 15.

Printed circuit board (PCB) 3 upper and lower surfaces have plurality of conducting strips 31.

Housing 5 is processed by metal material, is the kirsite material in the present embodiment, and it comprises procapsid 51 and is installed on the back casing 52 at procapsid 51 rear portions.Procapsid 51 comprise with the shaped as frame base portion 511 of the profile phase of insulating body 1 coupling, by shaped as frame base portion 511 around the receiving space 510 that forms, from base portion 511 mutually the back extension docking section 513 and be positioned at a pair of breach 514 of 513 rear ends, docking section.Form a step (not shown) between base portion 511 and the docking section 513.

Back casing 52 is formed in one, and has the receiving space 520 of accommodating stress relief element 6, ground loop 7, the through hole 521 that is positioned at its rear end and communicates with accepting groove 520.

Ground loop 7 is the metal material punch forming, and it has the retainer ring 71 identical with cable 4 profiles, cuts from forming and outwards open a pair of shell fragment 72 and outwards open shell fragment 72 and the breach 73 that forms from retainer ring 71.

During assembling, conducting terminal 2 inserts in the terminal groove 12 of insulating body 1 from back to front, and its fore-end is exposed in the grafting space 11, and its rear end part exposes to insulating body 1 rear end.Ground loop 7 is installed on the front portion of stress relief element 6 and the front end of cable 4; The braid of retainer ring 71 fixing cables 4 makes it not loosening; The cable 4 interior leads (not shown) that stress relief element 6 is coated are soldered on the conducting strip 31 of printed circuit board (PCB) 3, and cable 4 electrically connects with printed circuit board (PCB) 3.Ground loop 7 is positioned at stress relief element 6 front ends.The front end of printed circuit board (PCB) 3 inserts the rear portion of insulating body 1 from back to front, and the rear end of each conducting terminal 2 is respectively welded on the corresponding conducting strip 31.Insulating body 1 is contained in the receiving space 510 of procapsid 51; The step 13 of insulating body 1 offsets with the step (not shown) of procapsid 51; The grab 16 of insulating body 1 matches with the breach 514 of procapsid 51, makes the docking section 513 of procapsid 51 be contained in the accepting groove 520 of back casing 52 fully forward from the rear end of cable 4.Stress relief element 6 parts are contained in the through hole 521.
