DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention. Apparently, the embodiments described are merely partial embodiments of the present invention, rather than all embodiments. All the other embodiments derived by those having ordinary skills in the art on the basis of the embodiments of the present invention without going through creative efforts shall all fall within the protection scope of the present invention.

Referring toFIGS. 1 to 3, an electronic transfer card is provided according to an embodiment of the present invention, which is mainly used for achieving data function conversion between Mico SD and SD, to be specific, clamping a Mico SD UHS-II card in an electronic device to read data information. The electronic transfer card comprises a bottom shell1and an upper cover2located above the bottom shell1, both of which are correspondingly installed to enclose as an accommodating cavity3. The accommodating cavity3is provided with a socket31and a window32, wherein the socket31is mainly used for a clip piece to insert, that is to say, the Mico SD UHS-II card may be extended into the accommodating cavity3through the socket31, while the window32is used for an external electronic component to transmit the data information, that is to say, the data information of the Mico SD UHS-II card is conversed by the transfer card, and then transmitted to the electronic device to read. A first plastic component4and a second plastic component5are installed in the accommodating cavity3, which are both important electronic components for the data conversion function of the transfer card. The first plastic component4is clamped in the bottom shell1, and is provided with a plurality of first connecting terminals41. Each of the first connecting terminals41is a gold-plated contact piece, and is capable of electrically contacting with one group of contact points of the Mico SD UHS-II card. While the second plastic component5is provided with a plurality of second connecting terminals, each of the second connecting terminals51is also the gold-plated contact piece, and is capable of electrically contacting with the other group of contact points of the Mico SD UHS-II card. A function of golden finger of the transfer card may be formed through each of the first connecting terminals41and the connecting terminals51, so as to achieve the data information conversion in the Mico SD UHS-II card. In addition, the second plastic component5is further provided with an electric conduction portion52, through which the information transmission with the electronic component of the external electronic device may be formed. The electric conduction portion52shall be connected with each of the second connecting terminals51certainly. The conversed data information is transmitted through the electric conduction portion52to the electronic device for reading. The second plastic component5is also installed in the accommodating cavity3in a clamping form, and is partly overlapped in the first plastic component4. In the present invention, the first plastic component4is provided with the first connecting terminals41, the second plastic component5is provided with the second connecting terminals51. Both of the first plastic component4and the second plastic component5are moding pieces, and are subject to injection molding during manufacturing, so that the manufacturing process is very simple and the cost is very low compared with the manufacturing process of the traditional PCB. When both of the two are installed in the accommodating cavity3, a mechanical structure is used for clamping, and no welding is needed between two plastic components, so that both disassembly and assembly are relatively convenient. In addition, such fixing form is more applicable to the installation of automata. In this way, the yield of the product may be guaranteed, and the manufacturing cost of the transfer card may be further reduced during large batch production, so that the production efficiency is increased.

Referring toFIGS. 1, 3 to 5, further, the first plastic component4is provided with a first opening42and a second opening43, each of the first connecting terminals41is located in the first opening42, while each of the second connecting terminals51is extended from an end portion of the second plastic component5into the second opening43. In this embodiment, the first opening42is arranged directly with respect to the second opening43. Each of the first connecting terminals41is located in the first opening42, while each of the second connecting terminals51is located in the second opening43. When the Mico SD UHS-II card moves along the surface of the first plastic component4departing from the bottom shell1, a resisting action caused by each of first connecting terminals41and the second connecting terminals51, which limits the movement of the Mico SD UHS-II card, may be avoided, so that two groups of contact points of the Mico SD UHS-II card may be respectively contacted with each of the first connecting terminals41and the second connecting terminals51. Generally, the window32of the accommodating cavity3is opened in the bottom shell1, and the socket31is located at one end of the bottom shell1far away from the window32. The first plastic component4is arranged from one end of the bottom shell1close to the socket31to one end of the window32, while the second plastic component5is arranged from one end of the bottom shell1close to the window32to one end of the socket31, and both of the two are overlapped in a middle position of the bottom shell1, so that the Mico SD UHS-II card is engaged with the first plastic component4after it is extended from the socket31, and it facilitates the data transmission of the second plastic component with the electronic device through the window32at the same time.

Referring toFIG. 1andFIG. 6, the above embodiment is optimized, each of the first connecting terminals41and the second connecting terminals51is provided with a bending portion protruding out of a surface of the first plastic component4departing from the bottom shell1.

During manufacturing, the contact pieces are buckled, so that each of the first connecting terminals41and the second connecting terminals51is in a structural form of spring piece at a corresponding bending portion. When the Mico SD UHS-II card is extended into the accommodating cavity3through the socket31, the Mico SD UHS-II card is partly engaged with a surface of the first plastic component4at one side departing from the bottom shell1. As each bending portion protrudes out of the surface of the first plastic component4, the Mico SD UHS-II card produces a pressure to the bending portion of each of the first connecting terminals41and the second connecting terminals51. Of course, each of the bending portions produces a corresponding reactive force to the Mico SD UHS-II card, so that the bending portion may be contacted with the Mico SD UHS-II card stably. While in general, all of the bending portions of the first connecting terminals41and the second connecting terminals51are located in the same plane, that is to say, the height of each bending portion protruding out of the corresponding surface of the first plastic component4, the acting force of the Mico SD UHS-II card to each portion is the same, thereby avoiding a problem of unstable contact between one or more bending portions and the Mico SD UHS-II card.

In the present invention, as the second plastic component5is partly overlapped with the first plastic component4, and each of the second connecting terminals51needs to extend into the second opening43at the same time. For this embodiment, the second plastic component5is provided with the projection53structure, that is to say, a thickness of the second plastic component5corresponding to the second opening43is relatively large, so that it facilitates each of the second connecting terminals51to extend into the second opening43, and a connecting structure may be formed between the first plastic component4and the second plastic component5at the same time.

Referring toFIG. 2andFIG. 3, further, the bottom shell1is provided with a first recessed portion11and a second recessed portion12. A bottom surface of the second recessed portion12protrudes out of a bottom surface of the first recessed portion11, that is to say, a stepped structure is formed between the first recessed portion11and the second recessed portion12. The first plastic component4is provided with a first engagement surface and a second engagement surface. When the first plastic component4is installed in the bottom shell1, the first engagement surface is engaged with the bottom surface of the first recessed portion11, the second engagement surface is engaged with the bottom surface of the second recessed portion12, and the edges of the first plastic component4are successively snapped to the side walls of the first recessed portion11and the side walls of the second recessed portion12. In this embodiment, a clamping structure between the bottom shell1and the first plastic component4is refined, an inner bottom surface of the bottom housing1is in a structural form of stepped surface, so that the first plastic component4may be clamped and tightened in the first recessed portion11and the second recessed portion12. For a clamping structure between the bottom shell1and the second plastic component5, the side walls of the bottom shell1are provided with two cutting edges13, which are arranged opposite to each other, and the edges of the second plastic component5are snapped with the two cutting edges13. Of course, the two cutting edges13are not always arranged directly opposite to each other, but shall be arranged away from each other. The second plastic component5may be clamped and tightened through the two cutting edges13, and at the same time, the second plastic component5may be stably installed in the bottom shell1in combination with a connecting structure between the second plastic component5and the first plastic component4.

Referring toFIG. 1, further, the bottom shell1is removably connected with the upper cover2through a plurality of buckle structures, and each buckle structure is successively arranged along the edge of the bottom shell1at interval. The buckle structure may be in a structural form of a slot being matched with a pin. The pin is successively arranged along the edge of the bottom shell1at interval. The slot is arranged inside the upper cover2. After each pin corresponds to each slot one to one, the upper cover2is buckled on the bottom shell1, while when disassembling, both of the two need to be separated merely, which is relatively convenient.

Referring toFIG. 1andFIG. 2, an electronic device is further provided according to another embodiment of the present invention, comprising housing and a processor built in the housing. The housing is further internally provided with the above transfer card, the electric conduction portion52of which is electrically communicated with the processor.
