Abstract
The utility model discloses an interface wiring of a connecting line of an earphone microphone and a mainboard. The interface wiring comprises the connecting line, an earphone microphone interface and a mainboard interface, two ends of the connecting line are respectively connected with the earphone microphone interface and the mainboard interface, the earphone microphone interface is a four-pin plug with a pin spacing of 1.25 mm, and the mainboard interface is a double-row nine-pin plug with a pin spacing of 2.54 mm. According to the interface wiring, the design space of the integral structure is more full, the size of the interface is reduced, and the connection is stable and reliable.
Description
Technical field
The utility model relates to the interface winding displacement of a kind of ear microphone and mainboard connecting line.
Background technology
Audio amplifier line is used for connecting power amplifier and audio amplifier, wherein the current signal of circulation is much larger than said video line and tone frequency channel wire above, just because of signal amplitude is very large, this class line does not often have screen, for this wire rod, key is to reduce its resistance, because the output impedance of modern power amplifier is very low, so the requirement to audio amplifier line is also increased thereupon, as select sectional area large or stranded wire.Wire rod all has to silver line from fine copper, and a kind of audio amplifier line of somewhat expensive valency is oxygen-free copper audio amplifier industrial siding, and its main feature is to conduct electricity very well, and resistivity is low, has used its tone color in the time of playback sound to increase many.According to the classification of domestic loudspeaker box, be divided into home theater audio amplifier (generally having 6) and HIFI music audio amplifier (two), generally claim again fever case.
HIFI audio amplifier is for high-fidelity reduction recording sound field, so will have enough guarantees to the harmless transmission of audio signal.General transmission line has different impedances to different frequency signals, it is smudgy that this specific character shows as sound in the reduction of sound, people have produced a kind of high-grade audio amplifier connecting line that is called intelligent signal line for this reason, the feature of this line is that signal is divided into two passages according to frequency height, certain thickness outer layer line is by signal more than 5kHz, signal below 5kHz is by the internal layer transmission of line, and the frequency characteristic that this has just improved transmission line widely, makes the clear sound of playback penetrating.But price is also just very expensive, above the brand of said tone frequency channel wire, also mostly produce fever audio amplifier wire rod.
The signal of general device display device and power interface and power supply, analogue audio frequency, usb digital interface are standardized designs, do not consider the optimization under global design limited space and outwork condition, thus exist connector volume excessive, patch under large, the severe condition of work of inconvenience, loss the defects such as reliability reduction.Be unfavorable for the design instructions for use of high integration, high reliability outdoor equipment.
Utility model content
It is more abundant that the purpose of this utility model is to provide one to have overall construction design space, and interface volume reduces, stable connection, the feature such as reliable.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the interface winding displacement of a kind of ear microphone and mainboard connecting line, comprise connecting line, ear microphone interface and mainboard interface, the two ends of described connecting line are frames connecting with headphone microphone interface and mainboard interface respectively, described ear microphone interface is that contact spacing is the 4 contact pin plugs of 1.25mm, and described mainboard interface is that contact spacing is the double 9 contact pin plugs of 2.54mm.
In preferred embodiment of the utility model, the length of described connecting line is 105mm.
In preferred embodiment of the utility model, the diameter of described connecting line is 0.9mm.
The interface winding displacement of ear microphone of the present utility model and mainboard connecting line, has overall construction design space more abundant, and interface volume reduces, stable connection, the feature such as reliable.
Brief description of the drawings
Fig. 1 is the perspective view of interface winding displacement one preferred embodiment of the utility model ear microphone and mainboard connecting line;
In accompanying drawing, the mark of each parts is as follows: 1, ear microphone interface, 2, connecting line, 3, mainboard interface.
Embodiment
Below be only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, below with a preferred embodiment and accompanying drawing, the technical solution of the utility model is further described.
Consult Fig. 1, the interface winding displacement of a kind of ear microphone and mainboard connecting line, comprise connecting line 2, ear microphone interface 1 and mainboard interface 3, the two ends of described connecting line 2 are frames connecting with headphone microphone interface 1 and mainboard interface 3 respectively, the 4 contact pin plugs that described ear microphone interface 1 is 1.25mm for contact spacing, the double 9 contact pin plugs that described mainboard interface 3 is 2.54mm for contact spacing.
Further illustrate, the length of described connecting line is 105mm, and the diameter of described connecting line is 0.9mm.
The interface winding displacement of ear microphone of the present utility model and mainboard connecting line, comprise connecting line, ear microphone interface and mainboard interface, it is raw material that described connecting line adopts rubber covered wire, described ear microphone interface and mainboard interface adopt acrylic material, described connecting line frames connecting with headphone microphone interface and mainboard interface, described ear microphone interface is that contact spacing is the 4 contact pin plugs of 1.25mm, and described mainboard interface is that contact spacing is the double 9 contact pin plugs of 2.54mm.The length of described connecting line is 105mm, and the diameter of described connecting line is 0.9mm.Rubber covered wire also claims rubber sheath line, is a kind of two insulation wire rod; Crust and insulating barrier are quality of rubber materials, and conductor is fine copper.In wires and cables industry, insulating barrier uses haloflex (CPE) conventionally, and bearing temperature is-40 DEG C-105 DEG C, determines that by its performance rubber covered wire can only be used for the environment of low pressure, low frequency.Acrylic material is that the polymer that obtains of acrylicacidandesters Type of Collective is referred to as acrylic compounds resin, is that to synthesize up to now in transparent material matter the most excellent, and soft, good springiness, cold-resistant, high temperature resistant, oil resistant, UV resistant, pliability is good, and intensity is high, and this is not that general material is comparable.Controlling under the prerequisite of signal transmission quality, special purpose interface is improved to small-sized socket.For the designing requirement of self-organizing network system product, select cushion mode to improve multiple interfaces, make overall construction design space more abundant, interface volume reduces, and stable connection is reliable, particularly under bad working environments, has greatly improved the reliability connecting out of doors.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; everyly utilize equivalent structure or the equivalent flow process that the utility model specification and accompanying drawing content are done to slow down; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
