Abstract
The utility model relates to a plug and socket connector for earphone which belongs to wireless audio devices, comprising a stereo plug (1) and a stereo socket (5), which can not match with each other. The utility model has at least two monophonic plugs (2) and (3) with different diameters and a change-over switch (4). Each pole of the stereo plug (1) is respectively connected with every corresponding pole of the stereo socket (5). Two poles of the monophonic plugs (2) and (3), and earth pole (6) is connected with the public earth wire (7) of the stereo socket (5). The other pole is connected with any pole of both left and right of the stereo socket (5), and is connected with the other pole of the non-earth wire of the stereo socket (5) through the change-over switch (4) with the non-earth wire pole of the stereo socket (5) which is connected with the end of the monophonic plug. The utility model is suitable for various audio apparatus which are provided with different types of output sockets of earphones.
Description
The utility model relates to a kind of plug-socket connector, is specially adapted to the headset plug-socket connector of stereo set.
At present, the earphone accessory power outlet one of stereo set has four kinds: internal diameter is 6.3 millimeters a stereo jack, and internal diameter is 3.5 millimeters a stereo jack, and internal diameter is 3.5 millimeters a monophony socket; And internal diameter is 2.5 millimeters a monophony socket.Above-mentioned earphone can only be used with the earphone with diameter and identical sound channel.For this reason, stereo set manufacturer has produced multiple stereo set annex, the PC-34 of Sony Corporation for example, PC-8A, PC-36, PC-1A have solved the connectivity problem of stereophone and different inner diameters stereo jack and the connectivity problem of mono headset and different inner diameters monophony socket.But fail to solve for plug-socket connectivity problem between stereo and the monophony.
The utility model purpose is to provide a kind of headset plug-socket connector that is suitable for being equipped with the stereo set of dissimilar earphone sockets.
The utility model is achieved in that this headset plug-socket connector, comprise the stereo plug (1) and the stereo jack (5) that can not cooperate mutually, it have at least the monophony plug (2) of two different-diameters and (3) and one be connected stereo jack (5) non-ground wire and about the change over switch (4) of two interpolars; When switch (4) disconnected, each utmost point of stereo plug (1) respectively extremely linked to each other with the correspondence of stereo jack (5) respectively; In the two poles of the earth of monophony plug (2) and (3), the common ground (7) of earth polar (6) and stereo jack (5) is connected, and another utmost point extremely links to each other with the left and right sides of stereo jack (5) is arbitrary; Another extremely links to each other the non-ground wire of non-ground wire one utmost point of the stereo jack (5) that is not connected with the monophony plug by Closing Switch (4) and stereo jack (5).
The utility model just can be appreciated the signal of the stereo set that is equipped with dissimilar earphone sockets with this earphone, so convenient economical because only need re-use the utility model on the basis that has one pair of stereophone.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the I type electrical schematic diagram of headset plug-socket adapter of the present utility model.
Fig. 2 is the II type electrical schematic diagram of headset plug-socket adapter of the present utility model.
The electrical principle of I type and II type is identical, and for the person's of being used stereophone plug, the stereo jack of I type (5) internal diameter is 3.5 millimeters, and corresponding stereo plug (1) diameter is 6.3 millimeters; The stereo jack of II type (5) internal diameter is 6.3 millimeters, and corresponding stereo plug (1) diameter is 3.5 millimeters.The user can therefrom select a certificate to have with the model of internal diameter stereo jack according to the diameter of the plug of own stereophone to use.
Describe working condition of the present utility model in detail below in conjunction with accompanying drawing.
When functional switch (4) disconnects, (1) and (5) each extremely correspondence join, so just can solve the connectivity problem between stereo plug-socket.
When use monophony plug (2), when (3) listen to monophonic audio equipment, switch (4) closure.Like this, the left and right sides earphone parallel connection of stereophone.
Therefore, this product adds a kind of plug model that stereophone itself is had, and just has four kinds of dissimilar plugs, can satisfy and is equipped with the requirement that dissimilar earphone socket stereo sets are used.
Claims (1)
1, a kind of headset plug-socket connector, comprise the stereo plug (1) and the stereo jack (5) that can not cooperate mutually, it is characterized in that it have at least the monophony plug (2) of two different-diameters and (3) and one be connected stereo jack (5) non-ground wire about the change over switch (4) of two interpolars, when switch (4) disconnects, each utmost point of stereo plug (1) respectively extremely links to each other with the correspondence of stereo jack (5) respectively, in the two poles of the earth of monophony plug (2) and (3), the common ground (7) of earth polar (6) and stereo jack (5) is connected, another utmost point extremely links to each other with the left and right sides of stereo jack (5) is arbitrary, non-ground wire one utmost point of the stereo jack (5) that is not connected with the monophony plug, another of the non-ground wire by Closing Switch (4) and stereo jack (5) extremely links to each other.
