Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing:
See also Fig. 1 to shown in Figure 6, a kind of wire and cable connector, this wire and cable connector is a kind of SATA connector, and it mainly comprises an insulating body 1, some signal terminals 2, some power terminals 3, some leads 4, a cable 5, one first internal mold 61, one second internal mold 62 and a back cover 7.
This insulating body 1 comprises that a base portion 11 reaches from the docking section 12 that this base portion 11 extends forward, this docking section 12 is provided with two host cavities 121, all be provided with the passage 1211 that this insulating body 1 is run through in some front and back in two host cavities 121, these signal terminals 2 and power terminal 3 are installed in respectively in the passage 1211 of two host cavities 121, each signal terminal 2 is provided with a contact site 21 and an afterbody 22, each power terminal 3 is provided with a contact site 31 and an afterbody 32, and wherein afterbody 22,32 can stretch out backward from the passage 1211 of insulating body 1 rear end;
The end of each lead 4 extends a heart yearn 41, and each heart yearn 41 corresponding afterbody 32 with three power terminals 3 is electrically connected.
The end of this cable 5 extends some heart yearns 51, and each heart yearn 51 corresponding afterbody 22 with a signal terminal 2 of this cable 5 are electrically connected.
The rear end injection moulding of this insulating body 1 is formed with first internal mold 61 and second internal mold 62 of two independent separate, wherein first internal mold 61 is electric connections place that are coated between the heart yearn 41 of power terminal 3 afterbodys 32 and lead 4 ends, and second internal mold 62 is electric connections place that are coated between the heart yearn 51 of signal terminal 2 afterbodys 22 and cable 5 ends, makes and forms a comparatively firm electrical connection between cable 5 and signal terminal 2, lead 4 and the power terminal 3.This shell 7 is the peripheries that are overmolded onto two internal molds 61,62 once more, and its end is provided with two tension force and reduces structure 74,76.The both sides of this shell 7 respectively are fixed with a spiral shell spare 72, and this spiral shell spare 72 central authorities are provided with a screw 71, this wire and cable connector can be fixed on the casing (figure does not show) by using a bolt (figure does not show) to be located in this screw 71.
When making this wire and cable connector, its method comprises following step:
Step 1: prepare an insulating body 1 of having installed signal terminal 2 and power terminal 3;
Step 2: prepare some leads 4 and a cable 5, then heart yearn 51,41 correspondences of these cables 5 and lead 4 ends are welded to the afterbody 22,32 of these signal terminals 2 and power terminal 3, brush one deck glue (as epoxide-resin glue or PUR) again in the rear end of insulating body 1, seal the passage 1211 of this insulating body 1 rear end, the plastic material of fusion enters into this insulating body 1 inside from passage 1211 when preventing injection moulding;
Step 3: insulating body 1 is attached to a mould (figure does not show), PE (polyethylene) plastic material of fusion reinjects, the cooling back forms two internal molds 61,62 in the rear end of this insulating body 1, wherein first internal mold 61 envelopes the weld between these lead 4 ends and power terminal 3 afterbodys 32, and second internal mold 62 envelopes the weld between these cable 5 ends and signal terminal 2 afterbodys 22, makes cable 5 and signal terminal 2, lead 4 form a comparatively firm electrical connection with power terminal 3;
Step 4: after will being attached to another mould (figure does not show) through the spiral shell spare 72 that the insulating body 1 of injection moulding for the first time and two middle parts are provided with screw 71, PBT (polybutylene terephthalate (PBT)) plastic material of fusion reinjects, cooling back forms a shell 7 in the periphery of two internal molds 61,62, and this two spiral shell spare 72 promptly is combined as a whole with this shell 7 and is secured to the both sides of this shell 7.
The shell 7 of wire and cable connector of the present invention is to adopt the PBT material, because so PBT has the material that the better physical mechanical property relatively is suitable as shell 7, (temperature is 240 ℃ but temperature that needs during the injection moulding of PBT material and pressure are higher, pressure is 50KPa), if once directly injection mo(u)lding easily causes damage to the terminal 2,3 that exposes insulating body 1 rear end and electric connection place between the heart yearn 41,51 in the rear end of insulating body 1, cause the electric connection between cable 5 and signal terminal 2 or lead 4 and the power terminal 3 bad, cause the product yield lower.Therefore the present invention brushes the passage 1211 that one deck glue seals this insulating body 1 rear end in insulating body 1 rear end earlier, two internal molds 61 that constitute by the PE plastic material of injection mo(u)lding again, 62 envelope the weld between lead 4 and power terminal 3 and cable 5 and the signal terminal 2 respectively, because all lower (temperature is 150 ℃ for needed temperature and pressure when adopting the injection moulding of PE plastic material, pressure is 30KPa), thereby the damage that therefore can reduce weld obtains the high product qualification rate, coat two internal molds 61,62 make cable 5 and signal terminal 2 and lead 4 and power terminal 3 form a comparatively firm electrical connection after, again at two internal molds 61,62 peripheries are injected the PBT plastic material of fusion, injection mo(u)lding one has the PBT shell 7 of preferable mechanical strength, this shell 7 is coated on the line body of lead 4 and cable 5, and two tension force of these shell 7 ends reduce structure 74,76 can prevent that lead 4 and cable 5 from doing the time spent and damage being subjected to external tensile force.
The above; only be the preferable feasible embodiment of the present invention; can not therefore limit to interest field of the present invention; for example say that the present invention is by two internal molds 61 of injection mo(u)lding; 62 envelope heart yearn 41 and the heart yearn 51 of power terminal 3 and cable 5 ends and the weld between the signal terminal 2 of lead 4 ends respectively; and concerning the those of ordinary skill of being familiar with this area knowledge; with two internal molds 61; 62 merge into that an internal mold (figure do not show) envelopes the heart yearn 41 of lead 4 ends and the heart yearn 51 and the weld between the signal terminal 2 of power terminal 3 and cable 5 ends also is easy to do; such as use technical scheme of the present invention and technical conceive to make other various corresponding changes and distortion and change into, all these changes and distortion all should belong within the protection range of claim of the present invention.
