Description
[technical field]
The relevant a kind of plug cord cable connector that transmits voice signal of the present invention.
[background technology]
November in 2004, Chinese Taiwan on the 11st patent announcement disclosed a kind of plug construction M250397 number, and this plug includes an outer conductor, is formed with at least one electrode on the outer conductor; Be arranged with a linking sleeve in outer conductor near the tail end place; And in outer conductor, be plugged with a metallic axis, and the outer surface of axis is a shiny surface, this axis also is connected with electrode; And the top of axis and tail end connecting portion and protruding respectively being exposed to outside the outer conductor; And in the axis outer surface and be arranged with a positioning sleeve, in addition, be arranged with the headgear of a tool conical surface at the axis top end.Linking sleeve welds with external cable mutually, and pad is positioned at the outer surface of linking sleeve, and moulding one insulation gum cover in plug rear end coats this pad and cable.This pad size will certainly exert an influence to the size of insulation gum cover, if pad is excessive, the insulation gum cover that is positioned at the pad top so will approach.Because when welding, probabilistic factor was more, pad maybe be too high sometimes, can cause pad to expose to outside the insulation gum cover, plug in use, signal transmits stable inadequately.And along with the trend toward miniaturization of electronic equipment, such micro coaxial cable connector assembly is being assembled under the prerequisite than minor structure, it is stable that signal is transmitted.
Therefore, be necessary to provide a kind of wire and cable connector to overcome the problems referred to above.
[summary of the invention]
Main purpose of the present invention is to provide a kind of wire and cable connector of miniaturization.
For realizing above-mentioned purpose; The present invention can adopt following technical scheme: a kind of wire and cable connector; The insulation shell that it comprises plug, has the cable of some leads and attachment plug rear end and coat cable; Said plug comprises some contact sites of being positioned at its front end, links to each other with said contact site respectively and is positioned at the some weld parts of its rear end and the insulating material of said contact site and said weld part at interval respectively; Said weld part is that inside and outside multilayer is arranged, and said lead and said weld part weld respectively and form some pads, and said pad does not exceed the outer surface of outermost weld part.
Compared with prior art, the beneficial effect of wire and cable connector of the present invention is: the inhibit signal transmission stability, reduce the volume of existing wire and cable connector, and more help the wire and cable connector miniaturization.

Fig. 2 is the part three-dimensional assembly diagram of wire and cable connector of the present invention.
Fig. 3 is the three-dimensional assembly diagram of wire and cable connector of the present invention.
[embodiment]
Please referring to figs. 1 through shown in Figure 3, wire and cable connector 100 of the present invention comprises plug 1, the cable 2 of have some leads (indication) and attachment plug 1 rear end, coat the insulation shell 3 of cable 2 and be positioned at the peripheral shell body 4 of insulation shell.
As shown in Figure 1; Plug 1 is roughly the lengthwise cylindrical shape, comprises some contact sites 11 at its front end, at the weld part 12 of its rear end, the flange 13 and the insulating material 14 of contact site 11, weld part 12 at interval respectively between contact site 11 and weld part 12.Flange 13 outer surfaces exceed contact site 11 and weld part 13 outer surfaces.In the present embodiment, contact site 11 is three, is axis direction and side by side, be respectively applied for signal transmission, the transmission of L channel and R channel with audio jack plug direction.Weld part 12 also is three, is the concentric column cylinder of different-diameter size, and inside and outside multilayer is arranged, and in other embodiments, weld part 12 also can be other shapes.Weld part 12 is connected with corresponding contact site 11 respectively, and it comprises first weld part 121, second weld part 122 and the 3rd weld part 123.First weld part 121 is positioned at the center; The 3rd weld part 123 is positioned at outermost layer; And second weld part 122 is between first weld part 121 and the 3rd weld part 123, between first weld part, 121, the second weld parts 122 and the 3rd weld part 123 by insulating material 14 at interval.The 3rd weld part 123 is connected with flange 13, and second weld part 122 is compared the 3rd weld part 123 and compared second weld part 122 further from flange 13 away from flange 13, the first weld parts 121.The 3rd weld part 123 also has from its extension that extends back 124, and extension 124 exceeds first, second weld part 121,122 backward, and the outer surface of extension 124 is not higher than the outer surface of the 3rd weld part 123.
In the present embodiment, cable 2 has three leads, two holding wires 21 and an earth connection 22.Two holding wires 21 are respectively welded to first, second weld part 121,122, and earth connection 22 is soldered to the inner surface of extension 124.
As shown in Figure 2, insulation shell 3 forms for plastic shaping.The outer surface of insulation shell 3 is not higher than the outer surface of flange 13.Insulation shell 3 comprises internal layer 31 and the skin 32 that coats internal layer 31, and the front portion of internal layer 31 exposes to outer 32.Internal layer 31 coats the rear end of cable 2 and plug 1, its coated wire 3 and weld part 12.
As shown in Figure 3, shell body 4 is the plastic material that metal material or its surface are coated with metal level, the internal layer of its coated insulation housing 3, and its outer surface maintains an equal level with the outer surface of insulation shell 3, flange 13 mutually.
Because earth connection 22 welds the inner surface that the pad that forms is positioned at extension 124 mutually with the extension 124 of weld part 123; Its pad does not exceed the outer surface of the 3rd weld part 123, and has changed the welding manner that existing pad is positioned at the outer surface of the 3rd weld part 123.Make insulation shell 3 can have thicker thickness, the insulation shell 3 that can not cause the pad place is too thin and make pad expose insulation shell 3.Simultaneously, save the pad of the 3rd weld part 123 outer surfaces in the prior art, can make the volume of insulation shell 3 do forr a short time, help the miniaturization of wire and cable connector.
