Abstract

The utility model discloses a multipole plug, which is mainly used for earphones, loudspeakers, or microphones. The utility model comprises an insulating sleeve body and multi-sect contact pins which are fixed on the insulating sleeve body and provided with coaxial electrodes. Electrodes provided on the contact pin is divided by insulators; the plug also comprises a cylindrical electrode provided with the same axial center with the contact pin, and the cylindrical electrode is fixed on the insulating sleeve body; the insulator is provided between the contact pins and the cylindrical electrodes. The utility model also discloses another multipole plug, which comprises an insulating sleeve body and contact pins. The periphery of the contact pin is provided with plate sheet-shaped electrodes, and each plate sheet-shaped electrode is fixed on the insulating sleeve body. Insulators are provided between the contact pins and the plate sheet-shaped electrodes, or between plate sheet-shaped electrodes. Compared with prior art, the two above plugs provide more the channels of the transmission signal and increase the audio-visual function and the audio-visual effect. The lengths and manufacturing difficulties of the plugs aren't obviously increased.

Description

A kind of multi-pole plug

Technical field

The utility model relates to a kind of plug construction that is used for earphone, loud speaker or microphone, is meant a kind of multi-pole plug that can transmit multiple signals especially.

Background technology

Usually the multi-pole plug that is used on the stereo sets such as earphone, loud speaker or microphone at present mostly is three utmost points or four utmost points greatly, three-terminal polarized plus plug comprises that coaxial front end, middle pipe and outer tube respectively are a utmost point, isolated between each adjacent electrode with dead ring, and four utmost point plugs comprise in the coaxial front end, first that pipe and outer tube respectively are a utmost point in the pipe, second.Its main weak point is: (1) only can transmit three kinds or four kinds of signals, can't adapt to the audiovisual needs of the high development of audiovisual multimedia technology at all; (2) if along axis increase to five utmost points or more than, its plug size must extend, can't with host socket really sizing adapt, and the difficulty of making greatly improves.

Summary of the invention

The purpose of this utility model is to overcome the above deficiency of prior art, provide a kind of like product to have multi-electrode number of poles more than prior art but its length and manufacture difficulty all less than the multi-pole plug that obviously increases.

The purpose of this utility model can be achieved through the following technical solutions: design a kind of multi-pole plug, comprise the insulation body and be fixed on the insulation body, have a contact pin of more piece coaxial electrode, be separated by with insulator between each electrode on the contact pin, this plug also comprises the drum electrode that is provided with described contact pin concentric, drum electrode is fixed on the insulation body, has insulator between contact pin and drum electrode.

Described drum electrode has a plurality of, is separated by with insulator between each drum electrode; The front end of each drum electrode is not at grade.

Number of electrodes on the described contact pin is 2～4, and the quantity of described drum electrode is 2～6.

The front end of described contact pin stretches out outside drum electrode.

The purpose of this utility model can also be achieved through the following technical solutions: design a kind of multi-pole plug, comprise the insulation body and be fixed on the insulation body, have a contact pin of more piece coaxial electrode, be separated by with insulator between each electrode on the contact pin, this plug also comprises is located at described contact pin en plaque electrode on every side, each en plaque electrode is fixed on the insulation body, is being equipped with insulator between contact pin and the en plaque electrode and between each en plaque electrode.

Described en plaque electrode is located at the upper and lower of contact pin symmetrically, and every side has two en plaque electrodes, and two plate electrodes that are positioned at same side are set up at grade.

Number of electrodes on the described contact pin is 2～4.

Above two kinds of technical schemes of the present utility model, owing to around original multipole contact pin, also be provided with drum electrode or en plaque electrode, therefore this plug provides the passage of more transmission signals and has increased the function and the effect of audiovisual and its length and all not obviously increases of manufacture difficulty.

Specific embodiments

Fig. 1～4th, the schematic diagram of the preferred embodiment of first kind of technical scheme of the utility model, this multi-pole plug comprise the insulation body 1 and be fixed in the insulation body on, have four the joint coaxial electrodes contact pin 2, contact pin 2 stretches out from this insulation body 1, each electrode is respectively and manages pipe 5 and outer tube 6 in 4, second in the front end 3, first on the contact pin, is separated by by first dead ring 7, second dead ring 8 and the 3rd dead ring 9 between them.This plug also comprises interior cylindrical electrode 10 and the cylindrical tubular electrode 11 that is provided with described contact pin concentric, they have pin 101,111 respectively, drum electrode is fixed on the insulation body 1, all has insulating material 12 between contact pin 2 and the drum electrode 10 and between the inside and outside circle

tubular electrode

10,11, each dead ring 7,8,9 on described insulation body 1, the contact pin and be ejection formation of plastics at the insulating material between contact pin and the drum electrode and between the inside and outside circle tubular electrode 12.Thus, this plug has six electrodes, and they link to each other with corresponding wiring respectively, and then is connected to output of different sound channel or control signal, and convenient 5.1 sound channels or the high-fidelity result of broadcast of multichannel more of realizing also can realize the function of line traffic control simultaneously.

Fig. 5～9th, the schematic diagram of the preferred embodiment of second kind of technical scheme of the utility model, this multi-pole plug comprise equally the insulation body 13 and be fixed in the insulation body on, have four the joint coaxial electrodes contact pin 14, contact pin stretches out from this insulation body 13; The mechanism of this contact pin and contact pin shown in Figure 3 are basic identical, and each electrode is respectively in the front end, first and manages and outer tube in the pipe, second on it, is separated by by first dead ring, second dead ring and the 3rd dead ring between them.Different with first kind of scheme is, be provided with the electrode 15 of en plaque symmetrically at the upper and lower of this contact pin 14, every side has two to be positioned at conplane en plaque electrode, each en plaque electrode 15 and contact pin 14 are fixed on the insulation body 13, all have insulating material between en plaque electrode and the contact pin and between each en plaque electrode, this insulating material is ejection formation of plastics with insulation body, contact pin dead ring.Constituted plug thus with eight electrodes.
