Description

Audio socket

Technical field

The utility model is for providing a kind of audio socket, especially refer to be provided with modular a slice forming terminal structure in the body, pin in the holder that the body rear side is assembled then forms the packing crimping with terminal, hold with default motherboard in addition by plural pin again and be electric connection, and then the cost of simplification terminal arrangement and saving terminal mould, reach the purpose that reduces material cost and assemble man-hour simultaneously.

Background technology

Multi-media player is (as sound equipment at present, computer or DVD player etc.) used loud speaker, usually the loud speaker number of being exported with multi-media player is distinguished number of channels, for instance, play stereo as the music CD machine for two sound channels about utilizing, and for example 5.1 sound channels of sound card specification AC ' 97 standards in computer output, be to utilize five sound channels separated from one another to add a low-frequency channel to play, wherein each sound channel is all to there being a loud speaker to come sounding, the more sound card of new spec is also arranged, as AzAlia 7.1 sound channel specifications, by more sound channel, make the user enjoy better auditory effect.

Moreover; general multi-media player can be provided with audio connector usually on motherboard; and has the jack of supporting message output on the audio connector; insert connection for audio jack; see also shown in Figure 8; it is the three-dimensional exploded view of prior art; find out by knowing among the figure; the audio connector of the prior art is to have plastic casing A; signal terminal B and switch terminal C form; wherein plastic casing A one side is for being provided with plural jack A1; and in plastic casing A, be provided with the room A2 that interlinks with each jack A1; and jack A1 for inserting and butt up against in the room A2 for audio jack; the base portion B1 of signal terminal B then bends in the room A2 that is inserted into plastic casing A and contacts with audio jack; and be extended with under base portion B1 one side direction can be for the pin B2 that is connected with the preinstalled circuit plate; the base portion C1 of switch terminal C also bends in the room A2 that is inserted into plastic casing A in addition; and be extended with under base portion C1 one side direction can be for the pin C2 that is connected with the preinstalled circuit plate; after audio jack is inserted; whether can detect audio jack by the switching signal switching variation of switch terminal C inserts; if detecting is learnt when audio jack is inserted, can be come transmission signals by signal terminal B.

Yet, usually audio connector generally is to be provided with a plurality of jack A1 in upright stacked mode, and topmost the pin size of the terminal in the jack A1 also is the longest, and the production method of the signal terminal B of above-mentioned prior art audio connector and switch terminal C, normally come punching press to make by mould with sheet metal, be earlier required profile punching press to be come out, bending location moulding again, and with the pin B2 of signal terminal B and switch terminal C, C2, almost shared waste material area ratio is maximum, only need a pin but will waste very big material area, and then make terminal material cost demand very high, moreover, pin B2, C2 is when assembling, bent by the touching of external force or rupture, its structural strength is also very fragile, and distance is very intensive between between pin and the pin, when welding, cause the situation of pin dislocation to take place easily, also can increase the degree of difficulty that welds with the contraposition of circuit board because of a little error, and cause the flaw ratio of product itself to increase easily, and signal terminal B and switch terminal C are generally and separately design moulding, so the kenel of every butt also can be different, so just, need distinctly offer many group moulds and come the stamped terminal, promptly increase extra die cost.

Be with, relevant dealer is just arranged for solving the shortcoming of above-mentioned prior art, and utilize wiring board as switching, unnecessary waste problems with the pin that solves the prior art terminal, see also shown in Figure 9, it is the three-dimensional exploded view of another prior art, find out by knowing among the figure, this prior art mainly is that the signal terminal B of a slice moulding and switch terminal C are integrated on the wiring board D, again by wiring board D switching, signal can be transferred on the default motherboard, can solve the unnecessary waste problems of the pin of above-mentioned prior art terminal,, though this kind mode reduces the problem of terminal supportor waste material, but the wiring board that increases can improve the integral manufacturing cost on the contrary, in comparison, cost and expense can also be come highly than general audio connector, and on signal terminal B and the switch terminal C welding wiring board D time, the as easy as rolling off a log problem that failure welding occurs can improve the flaw ratio of product on the contrary.

Be with, how to solve above-mentioned prior art problems and shortcoming, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.

Summary of the invention

The inventor is to collect related data because above-mentioned problem and shortcoming, and via assessing in many ways and consider, and to engage in the many years of experience of the industry accumulation, via constantly studying and revising, the beginning is designed the utility model of this kind audio socket.

Audio socket of the present utility model includes insulating base frame, plural conductive terminal group and holder, wherein:

This insulating base frame front side offers the plural jack that can supply default audio jack to push, and is provided with the plural terminals groove that can supply the conducting terminal group to set around each jack; This complex conduction terminal group is for having signal terminal and switch terminal respectively, and each terminal all has the body that is positioned in the terminal groove, and is provided with the holding section in body one side, away from the holding section in addition side then be provided with the elastic arm that contacts with default audio jack; This holder surface is provided with the pin groove that can supply plural pin to place for cuing open, and when holder is incorporated into the insulating base frame rear side, plural number pin one end is for to be the packing crimped status with the corresponding holding section of complex conduction terminal group, and plural pin end in addition then forms electric connection with default motherboard.

The utility model beneficial effect is to be that the pin in the holder can be stamped terminals, package copper cash or wire rod, and the holding section that utilizes machine directly the pin front end in the holder directly to be stretched in the body with signal terminal and switch terminal forms the packing crimped status, have very clear and definite contraposition and clamp characteristic, and utilize the pin referral can simplify the configuration of terminal, and then can save the overall package cost in man-hour, and can improve the efficient of the manufacturing and the defect rate of reduction product.
