[detailed description of the invention]
Refer to shown in Fig. 1 to Fig. 5, micro coaxial cable connector assembly 100 of the present invention includes insulating body 1, the some conducting terminals 2 being contained in insulating body 1, the metal shell 3 of coated insulation body 1, connects the cable 4 of conducting terminal 2, the mesh grid 5 of cladding cable 4 and cladding metal shell 3, cable 4 and the insulation crust 6 of mesh grid 5.
As shown in Figure 1 to Figure 2, insulating body 1 includes that cave in the backward grafting space 11 formed, some terminal grooves 12 terminal groove 12 of being positioned at both sides, grafting space 11 of main part 10, main body 10 front surface runs through main part 10 front and rear surfaces and be connected with grafting space 11, in order to house conducting terminal 2.Conducting terminal 2 is divided into two rows, including the connecting portion 23 being positioned at the docking section 21 of its front end, the weld part 22 being positioned at its rear end and connecting welding portion 22 and docking section 21.
Metal shell 3 includes the fore shell 31 housing insulating body 1 and the back cover 32 matched with fore shell 31, and fore shell 31 is metallic plate punching molding, including a base plate 311.The leading portion of this base plate 311 forms the casket cave 312 of an all round closure, the back segment both sides of this base plate 311 radially projecting sidewall 313 respectively, and two side 313 is respectively equipped with draw-in groove 314.Back cover 32 also forms for metallic plate punching, both sides for sheet metal bend downwards and form the structure of three sidewall semi-surroundings, being respectively provided with the button portion 321 corresponding with draw-in groove 314 on two of which sidewall, the rear end of back cover 32 also has the fixing ring 322 for holding cable 4.
Cable 4 includes some conductors 41, the interior insulated hull 42 of parcel wire 41, the braid 43 of the interior insulated hull 42 of cladding and the external insulation skin 44 of parcel braid 43 welded respectively with weld part 22 phase of conducting terminal 2.The braid 43 of exposed external insulation skin 44 front end turns up backward, and the braid 43 after turning up is coated with external insulation skin 44.
Mesh grid 5 is the network structure that a kind of high-strength metal material is passed through to be knitted to form, such as alloyed copper, copper foil wire or copper covered steel etc..Seeing on the whole, mesh grid 5 is cylindrical shape, and on its braid 43 turned over after being retained on by riveting or other modes, the intensity of mesh grid 5 is higher than the intensity of braid 43.Mesh grid 5 has preferable pliability, and by less external force, mesh grid 5 can bend.
Insulation crust 6 includes the protection portion 61 being coated with metal shell 3 and is coated with the stress relief element 62 of cable 4 and mesh grid 5.In present embodiment, protection portion 61 and stress relief element 62 are integral type structure, and in other embodiments, protection portion 61 and stress relief element 62 can be split-type structural, and both assemble respectively or be molded in metal shell 3 and cable 4 and mesh grid 5.
