In order to protect the USB plug of exposure, USB connector can be designed to revolving concealed structure.In one embodiment of this invention, described USB connector body comprises housing and rotary body, the end of this rotary body is provided with USB attachment plug, this housing is sheathed on the outside of rotary body and offers through hole at tail end, the transmission electric wire is located in this through hole, rotary body is articulated in the front end of housing, and is the center rotation with the pivoting point, and the housing two sides are to be used for the opening that the rotary body rotation is passed through.
In technique scheme, described USB connector can also be designed to the rotary body two ends and be respectively equipped with USB attachment plug and a small-sized USB attachment plug, the other end of described rotary body is located in its middle-size and small-size USB attachment plug, relative with USB attachment plug, two audio signal links of described audio frequency attachment plug connect two single data signal connection ends of small-sized USB attachment plug respectively, the ground link of audio frequency attachment plug is connected with the ground link of small-sized USB attachment plug, and the control signal end of audio frequency attachment plug connects the power end of small-sized USB attachment plug.
Audio frequency attachment plug in technique scheme can be 2.5 or 3.5 audio frequency attachment plugs.
Based on technique scheme, the utlity model has following advantage:
1, the utility model is respectively equipped with USB connecting portion and audio frequency connecting portion at the multiplexing transmitting line two ends, can pass through the USB interface transmission of data signals, also can pass through audio frequency input/output interface transmitting audio signal, realizes the connection between the different interface devices.
2, the utility model utilizes a kind of rotational structure that usb segment is protected, and has also designed the USB connector that comprises generic USB plug and small-sized USB plug simultaneously, can satisfy the needs of the equipment that uses USB plug or small-sized USB plug.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
