It is new to this practicality below in conjunction with attached drawing to make the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
The first embodiment of the utility model provides a kind of mobile phone protective cover of tape relay interface, with reference to shown in Fig. 1, including
Set of shells 4, interface conversion is protected to expand plate 3, interface conversion expansion plate cover board 2.It is with right angle that interface conversion, which expands plate cover board 2,
The plate body of bending connect to form an enclosure space, be sealed in above-mentioned enclosure space with one end inside protection set of shells 4
Plate 3 is expanded equipped with interface conversion.For mobile phone protective cover housing 4 is made to be tightly engaged into mobile phone 1, the inner cavity of mobile phone protective cover housing 4
Shape is made according to specific 1 type design of mobile phone, therefore the protection set of shells 4 of the utility model, interface conversion are expanded
Plate cover board 2 is similary with the position that mobile phone 1 engages to be ensured to be fitted close with mobile phone 1 with 1 form fit of mobile phone.
The utility model is to protecting set of shells 4 and the material of interface conversion expansion plate cover board 2 not to do particular determination, every energy
Enough materials to play a protective role to mobile phone, such as plastics, rubber, metal, timber etc..Based on above-mentioned material, interface turns
It changes and expands plate cover board 2 with protecting being fixedly connected with mode and being hot pressing plastic packaging, be glued, the modes such as snap connection for set of shells 4.
It is expanded on plate 3 in interface conversion and is integrated with various forms of circuit interfaces, connect including first kind interface and the second class
Mouthful, first kind interface and the second class interface are expanded on plate 3 in interface conversion and are electrically connected.The first kind interface of above-mentioned meaning refers to
The utility model is used for the circuit interface being connect with mobile phone, and the second class interface refers to the utility model for being connect with external equipment
Circuit interface.In order to provide multiple and external equipment connecting interface to mobile phone, interface conversion, which is expanded, includes at least two on plate 3
Second class interface, a charging for being used for mobile phone, remaining is used for transmission signal, can also pass through it while charging the phone
Its interface externally transmits audio signal.The type of above-mentioned first kind interface or the second class interface includes but not limited to Type-C and connects
Mouth, Lightning interfaces, microUSB interfaces, 3.5Plug interfaces etc. are suitable for the interface of mobile phone.Various forms of interface categories
In the prior art, the circuit connecting mode that plate 3 is expanded with interface conversion also belongs to the prior art, and those skilled in the art can
Size, material and the number of plank are selected according to actual conditions.
First kind interface with the charging interface of mobile phone for connecting, towards the charging interface that should be directed toward mobile phone.Due to
The charging interface of mobile phone is interface female seat, therefore the first kind interface form of the utility model should be interface plug.Turn in interface
It changes and expands 3 position corresponding with first kind interface of plate cover board equipped with the through-hole with first kind interface form fit, ensure the first kind
The interface plug of interface can stretch out interface conversion and expand other than plate cover board 2.
For second class interface for being connect with external equipment, direction should be directed toward outside.Due to the interface shape of external equipment
Formula is interface plug, therefore the form of the second class interface of the utility model should be interface female seat.In protection set of shells and second
The corresponding position of class interface is equipped with the through-hole with the second class interface form fit, ensures that the interface plug of external equipment can
It is inserted into the interface female seat of the second class interface.
There is provided second embodiment on the basis of first embodiment, first kind interface is Type-C interfaces, the second class interface
For Type-C interfaces and 3.5Plug interfaces, the second class interface includes at least two Type-C interfaces.Type-C interfaces are big at present
The charging interface form of most cell phone manufacturers has the function of the audio that charges and transmit.First kind interface obtains connection with mobile phone,
The the second class interface integrated on plate 3 is expanded by interface conversion again to connect with external equipment.The form of second class interface is Type-
C interface, compatible decoding chip and 3.5Plug interfaces, the 3.5Plug are not united due to current mobile phone Type-C output signals
One, respectively digital or analog signal, therefore can decide whether additional core according to the Type-C digital or analog signals exported
The mode of piece makes its compatibility more extensive, and the size and model of chip can carry out arbitrary type selecting, number according to existing technical staff
Signal directly exports audio after conversion by 3.5Plug interfaces, and the Type-C interfaces are Type-C digital signals, therefore
Digital audio directly can be exported by Type-C interfaces in the case where being converted without signal.
In circuit connection, with reference to shown in Fig. 2, first kind interface respectively with the 3.5Plug interfaces in the second class interface with
And second any Type-C interfaces in class interface be electrically connected, connect between each Type-C interfaces in the second class interface
It connects.The external signal output interface of the present embodiment has both 3.5Plug interfaces and Type-C interfaces, meets user to distinct interface shape
The demand of formula.Second class interface includes two Type-C interfaces, can meet the needs of charging and output audio simultaneously, facilitate use
Family uses.
3rd embodiment is provided on the basis of first embodiment, first kind interface is Lightning interfaces, and the second class connects
Mouth includes Lightning interfaces and 3.5Plug interfaces, and the second class interface includes at least two Lightning interfaces.
Lightning interfaces are the charging interface form of iPhone, have the function of the information that charges and transmit.First kind interface and hand
Machine obtains connection, then expands the second class interface integrated on plate 3 by interface conversion and connect with external equipment.Second class interface
Form is Lightning interfaces and 3.5Plug interfaces, since the output signal of mobile phone is Lightning format signals,
Lightning format signals are digital signal, and needing to be converted to analog signal could be exported by 3.5Plug interfaces, therefore also
It needs that digital signal is switched to analog signal there are one DAC decoding chips.
In circuit design, with reference to shown in Fig. 3, first kind interface respectively in DAC decoding chips level-one the second class interface
Any Lightning interfaces are electrically connected, and DAC decoding chips are also electrically connected with the 3.5Plug interfaces in the second class interface, the
It is connected between each Lightning interfaces in two class interfaces.The external signal output interface of the present embodiment has both 3.5Plug
Interface and Lightning interfaces meet the needs of iPhone user is to distinct interface form.Second class interface includes two
Lightning interfaces can meet the needs of charging and output audio simultaneously, user-friendly.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
