Second insulating part, 21 front ends are provided with some passage 211, the second insulating parts 21 rear ends of accommodating and are provided with a reception room 212.Accommodating passage 211 communicates with reception room 212.Reception room 212 extends along longitudinally, accommodates passage 211 edges and the perpendicular direction extension of reception room 212 bearing of trends.Reception room 212 extends back and forms a lengthwise type and widen fixing piece 213, and this fixing piece 213 is provided with the slit 214 of some lengthenings, and it runs through the rear surface 215 of second insulating part 21 and communicates with reception room 212.In the present embodiment, cable 6 is eaten the tin hardening after having welded length is approximately 1.0mm～1.5mm, so the slit of lengthening is 1.5mm.Some cables 6 pass slit 214 and are contained in reception room 212 and accommodate in the passage 211.
Signal terminal has identical structure with earth terminal 22.Each terminal 22 includes holding parts 221, reaches the connecting portion 223 that extends back from holding parts 221 from the docking section 222 that holding parts 221 extends forward.Each docking section 222 is provided with upper surface 2221 and relative with upper surface 2221 and be used for and dock the contact-making surface 2222 that electric connector (not shown) is connected.Each connecting portion 223 includes the solder side 2231 that is used for welding mutually with the lead of cable and reaches and solder side 2231 opposing lower surface 2232.Between holding parts 221 and connecting portion 223, be formed with step 224, thereby make the upper surface 2221 of docking section 222 be higher than the solder side 2231 of connecting portion 223.Docking section 222 is used for electrically connecting with docking electric connector, and connecting portion 223 is used for electrically connecting with the heart yearn 61 of cable 6.
Earth electrode 23 includes the main part 231 of longitudinal and some ground connection finger 232 that autonomous body 231 extends forward.
Some cables 6 include some high-speed transfer leads and some power leads.In the present embodiment, cable 6 is ultra-fine coaxial cable (Micro Coaxial Cable), and is made up of heart yearn 61, inner insulating layer 62, braid 63 and external insulation layer 64.
See also Fig. 3 and shown in Figure 4, during assembling, signal and earth terminal 22 are organized respectively to go into to accommodate in the passage 211, and wherein the connecting portion 223 of terminal 22 is contained in and accommodates in the passage 211, and the front end face of second insulating part 21 is extended in holding parts 221 and docking section 222.The solder side 2231 of the connecting portion 223 of terminal 22 is revealed in accommodates in the passage 211.The heart yearn 61 of cable 6 is placed on the solder side 2231 of terminal 22, and the front end of cable 6 is contained in the slit 214 on the fixing piece 213.Some scolding tin are positioned over to accommodate in the passage 211 and with the heart yearn 61 of cable 6 and the solder side 2231 of terminal 22 and contact.The hot blast that firing equipment blows out flows to terminal docking section 222, and terminal 22 is effectively passed to scolding tin with heat like this, and the connecting portion 223 with terminal 22 after the melts soldering tin links together with heart yearn 61.Earth electrode is gone into reception room 212 for 23 groups, and ground connection finger 232 extends into correspondence and accommodates in the passage 211 and the solders side 2231 of terminal 22 contact, and its main part 231 is contained in the reception room 212.Ground connection finger 232 welds together with the solder side 2231 of corresponding terminal 22, and main part 231 welds together with the braid 63 that is contained in the cable 6 of reception room 212.Because the upper surface 2221 of the docking section 222 of terminal 22 and the solder side 2231 of connecting portion 223 not coplane and upper surface 2221 are higher than this solder side 2231, after the melts soldering tin that is placed on the solder side 2231, scolding tin can not flow to the upper surface 2221 of docking section 222, has effectively avoided the phenomenon of being transmitted by scolding tin pollution effect signal because of the docking section.
Ground plate is gone into first insulating part 1 for 24 groups.21 groups of second insulating parts are gone in the longitudinal flat board 131 at rear portion 13 of first insulating part 1, wherein the two ends of second insulating part 21 are contained in accommodating in the conduit 141 of resettlement section 132 respectively, the holding parts 221 of terminal 22 and docking section 222 are contained in the corresponding groove 111 of first insulating part 1, and the holding parts 221 and first insulating part 1 are interference engagement.Owing to can not flow to the holding parts 221 and the docking section 222 of terminal 22 after the melts soldering tin, the interfering edge that second insulating part 21 is easy to organize between first insulating part 1 and first insulating part 1 and the terminal 22 can not increase, can not produce the phenomenon of tin pollution docking section 222, guarantee the reliability of signal transmission.
The technology of utilization point glue sticks together the external insulation layer 64 and the slit 214 of cable 6 front ends again.Because the braid 63 of cable 6 front ends is eaten the tin hardening in main part 231 backs of having welded earth electrode 23 because of the capillary effect of tin liquor and braid 63, and cable 6 front ends of hardening are contained in the slit 214 of lengthening firmly, so braid 63 fractures of cable 6 with regard to not making cable 6 front ends because of the effect of external force.
First insulating part 1 is assembled in the receiving space 34 of shielding casing 3.The sidepiece 35 of being located at the guiding groove 142 guiding shield shells 3 of first insulating part 1 inserts, projection 113 is contained in the perforation 37, shell fragment 36 extends in the reception room 212 and with earth electrode 23 and is connected, and 38 depressions 143 with the maintaining part 14 of first insulating part 1 of shell fragment match.Ground plate 24 is between the upper shell 31 of second insulating part 21 and shielding casing 3.Like this, 100 assemblings of whole micro coaxial cable connector assembly are finished.
