Abstract

The utility model relates to a removable memory used to realize the information exchange with electronic equipments, which comprises a shell and a circuit board arranged in the shell. The shell comprises an upper shell and a lower shell which are connected with each other; the lower shell is provided with a lower base and an extending part which extends outwards from a side of the lower base; the circuit board is arranged in the base and the extending part of the lower shell, and comprises a circuit part and a conductor; the circuit part is arranged in the base of the lower shell; the conductor is arranged in the extending part of the lower shell, and the conductor is in an integrated electrical connection with the circuit part. Because the conductor and the circuit part of the removable memory are in an integrated connection, and the additional arrangement of an adapter is not needed, the volume of the removable memory can be reduced, and then the carrying is convenient.

Description

Mobile memory

[technical field]

The utility model is about a kind of mobile memory, especially can peg graft to realize the mobile memory of message exchange with the corresponding interface of electronic equipment about a kind of.

[background technology]

Existing mobile memory as flash disk, is in order to peg graft with the corresponding interface of the electronic equipment (as computing machine) of outside, to realize the transmission of data.General mobile memory comprises housing parts and breakout box, be equipped with circuit board in this housing parts, this breakout box is provided with the conducting terminal that can be electrically connected with electronic equipment, and the breakout box periphery is covered with metal shell, breakout box is electrically connected with USB interface of computer, simultaneously this metal shell and case of computer ground connection.Yet,,, can not satisfy the compact day by day trend of portable equipment so this mobile memory volume is bigger because mobile memory need be established breakout box in addition.

[utility model content]

The purpose of this utility model is to provide a kind of frivolous portable mobile memory.

The purpose of this utility model is achieved in that a kind of mobile memory, it comprises housing and circuit board, it is characterized in that: the extension that housing is provided with matrix and is provided with from matrix one side one projection, circuit board is provided with circuit part and electric conductor, this circuit board is placed in the matrix and extension of this housing, electric conductor is located at this circuit board and is placed in part in this extension, and this electric conductor is electrically connected with the circuit part one that this circuit board is placed in the matrix.

Compared with prior art, the utlity model has following advantage: because of the electric conductor of mobile memory is connected with the circuit part one, and need not to establish in addition breakout box, thereby can reduce the volume of mobile memory, and then be easy to carry.

[embodiment]

See also Fig. 1 to Fig. 4, the utility model mobile memory comprises housing 11 and is placed in its interior circuit board 12, housing 11 parts comprise the upper shell 111 and the lower house 112 of interconnective longitudinal, are formed with the receiving space of accommodating circuit board 12 between this upper shell 111 and the lower house 112.Upper shell 111 comprises that matrix 1111 reaches from going up 1,111 four lateral margins of matrix respectively to the extended upper side wall 1112 of lower house 112 directions on one, and the projection that links to each other on these four upper side walls 1112 is provided with raised line 1113.Lower house 112 is " protruding " font, it comprises the lower substrate 1121 of a longitudinal and the extension 1122 that is provided with in the outside one projection of 1121 lateral sidewalls middle positions of this lower substrate, lower substrate 1121 comprises four lower wall 1123 and first accepting groove 1124 that is enclosed to form therebetween, be provided with in corresponding raised line 1113 positions of going up matrixes 1111 of 1,121 four lower wall of lower substrate 1123 can with the slit 1125 of its fastening, thereby make these four lower wall 1123 roughly be " returning " shape, and be provided with a breach in lower substrate 1121 horizontal sidewalls, extension 1122 is provided with to extending away from lower substrate 1121 directions in horizontal direction from this lateral sidewalls, this extension 1122 is concaved with second accepting groove 1126 that connects with lower substrate 1,121 first accepting grooves 1124, the end of this second accepting groove 1126 and with the bottom surface coplane of the breach of lower substrate 1121.Circuit board 12 is " protruding " font, it comprises circuit part 121 and interface section, circuit part 121 is placed in first accepting groove 1124 of lower substrate 1121, the interface section is placed in second accepting groove 1126 of extension 1122, wherein circuit part is an electronic circuit, the interface section is four electric conductors 122 that are electrically connected with circuit part 121, it is a golden finger in the present embodiment, these four golden fingers are respectively in order to connect+power lead 1221 of 5 volts of power supplys, in order to connect the Data-of signal,

Data+ signal wire

1222,1223 and earthy ground wire 1224, wherein+5 volt power lead 1221 is in order to connect so that this mobile memory power supply to be provided with external electronic, Data-,

Data+ signal wire

1222,1223 in order to realize the exchange back and forth of data with the electronic equipment that docks, and ground wire 1224 is in order to play ground connection.

Because the electric conductor 122 that connects with electronic equipment in the utility model mobile memory is electrically connected with circuit part 121 one of circuit board 12, and need not the breakout box established by other, so can reduce volume and then be easy to carry.
