The multifunctional external plug wire can be used as an external power lead of a flashlight with a speaker (or other similar products), an input lead of an audio signal or an external antenna, thus the multifunctional external plug wire has multiple uses, saves cost and is convenient to carry.
Description
Technical field
The utility model relates to a kind of electric fittings, is specially the outer patch cord of a kind of two ends band plug.
Background technology
Top, market LED flashlight has the digital acoustics function, and (in present specification, abbreviating band sound equipment flashlight as) comprises function of radio receiver and MP3 playing function etc.Because the restriction of inner space generally only is equipped with built-in loudspeaker, be dual track output when adopting earphone output, be mono-operation when adopting built-in loudspeaker.Owing to adopt rechargeable battery and special-purpose power amplifier chip, power is sufficient, so have enough big sound output and good tonequality, is well suited for being used for doing the external active audio amplifier of some other sources of sound such as iPhone.But the problem that existing product in use exists has:
The one, its external charge power supply generally adopt USB port+the 5V power supply, so need wear one one end for the USB plug other end is the line of 3.5mm standard plug, special-purpose line is used as charging; And need wear the signal input link that two ends all are the 3.5mm standard plug during as active audio amplifier; Need wear two different external lines like this, increase cost, also cause and carry inconvenience.
The 2nd, its FM function of radio receiver operating frequency is at 87-108MHz, and corresponding antenna length the best is about 75cm, so the realization of function of radio receiver need be used external antenna.Existing product is to adopt external earphone wire to serve as antenna, and when headset plug inserted accessory power outlet, the antenna input of radio reception circuit was connected to earphone wire as external antenna through plug.Headset plug is the 3.5mm standard plug, belongs to standard component, and structure is all the same; Comprise handgrip and insert axle, slotting the tip of the axis has cone tip, when plug insertion socket; Inserting the cone tip of shaft end can back down the linked switch of socket the inside, cuts off the work of built-in loudspeaker.This causes a problem: need insert earphone in the time of listening to radio reception or other plug wires are used as external antenna; And just cut off built-in loudspeaker automatically in case insert plug; Can't use the bigger built-in loudspeaker of volume to listen to radio reception, obviously this also causes the very inconvenience in the use.
Summary of the invention
The utility model purpose is open a kind of so multi-functional outer patch cord, and it can go between as external power supply, also can be as the input lead of audio signal, and further, it can also be as external antenna.
The utility model includes lead-in wire, it is characterized in that: an end of lead-in wire is connected with a 3.5mm tack plug, and the other end of lead-in wire is connected with a USB plug and a 3.5mm standard plug simultaneously.
Said 3.5mm tack plug includes handgrip and inserts axle, and slotting axle is provided with three circular conducting rings, and slotting the tip of the axis is the tack top.
On being electrically connected; The ground wire of the ground wire of USB plug and 3.5mm standard plug is connected to first conducting ring of 3.5mm tack plug simultaneously as common ground; The power positive end of USB plug is connected to second conducting ring of 3.5mm tack plug as power input, and the signal end of 3.5mm standard plug is connected to the 3rd conducting ring of 3.5mm tack plug as signal input part.
The outer patch cord of the utility model both can be used as the external power supply lead-in wire of band sound equipment flashlight (or other similar products), also can be used as the input lead of audio signal, and a line is dual-purpose, provides cost savings, and also is convenient for carrying.Wherein an end adopts 3.5mm tack plug; When the tack plug inserts the accessory power outlet of band sound equipment flashlight, can the linked switch of socket the inside not backed down, can not cut off the work of built-in loudspeaker; So can use the bigger built-in loudspeaker of volume to play, use more flexible.
Description of drawings Fig. 1 is the structural representation of the outer patch cord of the utility model.
Fig. 2 is the structural representation of 3.5mm tack plug wherein.
Embodiment
Among Fig. 1, the outer patch cord of the utility model comprises the lead-in wire L1 of multicore, and lead-in wire L1 length is about 75cm, is the antenna optimum length of FM frequency range.It is P1 that the end of lead-in wire L1 is connected with a 3.5mm tack plug, and it is that P2 and a 3.5mm standard plug are P3 that the other end of lead-in wire L1 is connected with a USB plug simultaneously.Wherein USB plug and 3.5mm standard plug all are standard components.
Fig. 2 is that the tack plug of the utility model is the structural representation of P1.The structure of tack plug P1 is similar with the 3.5mm standard plug, equally includes handgrip P11 and inserts axle P12.Insert axle P12 and be provided with three circular conducting rings i.e. first conducting ring P13, the second conducting ring P14 and the 3rd conducting ring P15.Tack plug P1 is with the difference of 3.5mm standard plug: the 3.5mm standard plug has cone tip at slotting shaft end, when plug insertion socket, inserts the cone tip of shaft end and can the linked switch of socket the inside be backed down, and cuts off the work of built-in loudspeaker.And the slotting shaft end of 3.5mm tack socket partly removes cone tip, and becoming does not have the tack of cone tip top P16.When the tack socket inserted accessory power outlet, owing to there is not cone tip, the tack plug can not back down the linked switch of socket the inside, just can not cut off the work of built-in loudspeaker yet.So the accessory power outlet with P1 inserts band sound equipment flashlight can continue again to use built-in loudspeaker to play with outer patch cord as external antenna.
Be electrically connected, through the multicore line of lead-in wire L1 the inside, USB plug is that ground wire and the 3.5mm standard plug of P2 is the ground wire of P3, and the first conducting ring P13 that is connected to 3.5mm tack plug simultaneously and is P1 is as common ground.USB plug+the second conducting ring P14 that the 5V power end is connected to 3.5mm tack plug is as power input, and the signal end of 3.5mm standard plug is connected to the flat P15 of the 3rd conducting ring of 3.5mm tack plug as signal input part.Because band sound equipment flashlight and similar products generally only have built-in loudspeaker, so when the 3.5mm standard plug adopted the dual track plug, the signal end of two sound channels linked together and uses as monophony.
Like this, can USB plug be inserted the USB socket of other electrical equipment, obtain USB port+the 5V power delivery is to the P14 of tack socket, as the input of external power supply.Also can standard plug P3 be inserted the audio frequency accessory power outlet of other electrical equipment, obtain audio signal and be transported to P15,, utilize built-in power amplifier and loudspeaker to play as the input of external audio frequency signal.Reach the purpose of joint use.Even; Band sound equipment flashlight can also adopt a multiconductor jack to obtain simultaneously power supply input and the audio signal input of tack plug P1; And USB plug and 3.5mm standard plug can insert the USB socket and the signal accessory power outlet of other products simultaneously; Make band sound equipment flashlight can when working, directly adopt external power supply, prolong the life-span of built-in rechargeable battery as active audio amplifier.
