Memory card adapterMemory card adapter description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20080070427, Memory card adapter. Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001](a) Field of the Invention [0002]The present invention relates to a memory card adapter and more particularly, to such an improved structure of memory card adapter for express card slot of a notebook computer. [0003](b) Description of the Prior Art [0004]A conventional memory card adapter for express card slot is known comprised of a multi-in-one memory card slot, a PC board, a connecting port, and an electrically insulative housing. Due to the limitation of the express card thickness to be within 5 mm, an elevation difference exists between the multi-in-one memory card slot and the connecting port at the PC board. To overcome this elevation difference, the electric connection between the multi-in-one memory card slot and the PC board is achieved by means of arranging curved metal terminals in the multi-in-one memory card slot and soldering the curved metal terminals to respective metal contacts at the PC board. However, it is difficult to accurately arrange the curved metal terminals in a limited space within a limited height inside the multi-in-one memory card slot. A small positioning error of the curved metal terminals in the multi-in-one memory card slot will result in an electric connection error. In consequence, the processing and installation of the curved metal terminals are complicated, resulting in a high manufacturing cost of the memory card adapter. [0005]Therefore, it is desirable to provide a memory card adapter that eliminates the aforesaid problems. SUMMARY OF THE INVENTION [0006]The present invention has been accomplished under the circumstances in view. According to one aspect of the present invention, the memory card adapter is comprised of a connecting substrate, a memory card connector, a connecting terminal set, a PC board, and an electrically insulative housing, wherein the connecting substrate and the connecting terminal set constitute a bridge to electrically connect the memory card connector and the PC board, thereby simplifying the installation of metal terminals and achieving the effects of increasing the yield rate and lowering the cost. According to another aspect of the present invention, the electrically insulative housing has a rectangular frame with two locating holes and two cove shells covered on the top and bottom sides of the rectangular frame, and the PC board has an electric connector, which has two locating blocks respectively engaged into the locating holes of the rectangular frame of the electrically insulative housing to secure the printed circuit board to the rectangular frame of the electrically insulative housing. BRIEF DESCRIPTION OF THE DRAWINGS [0007]FIG. 1 is an exploded view of a memory card adapter in accordance with the present invention. [0008]FIG. 2 is an exploded view of the connecting substrate, connecting terminal set and PC board of the memory card adapter according to the present invention. [0009]FIG. 3 is a side view of a part of the present invention, showing the connection between the connecting substrate and the PC board. [0010]FIG. 4 is an exploded view of the present invention, showing the parts of the memory card adapter assembled before mounting of the cover shells of the electrically insulative housing. [0011]FIG. 5 is an oblique elevation of the memory card adapter according to the present invention. [0012]FIG. 6 is a longitudinal sectional view of the memory card adapter according to the present invention. [0013]FIG. 7 is a top view of the memory card adapter according to the present invention. [0014]FIG. 8 is another exploded view of the memory card adapter according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0015]Referring to FIGS. 1.about.8, a memory card adapter in accordance with the present invention is shown comprised a connecting substrate 1, a memory card connector 2, a connecting terminal set 3, a PC board 4, and an electrically insulative housing. [0016]Referring to FIGS. 1.about.3, the connecting substrate 1 has a window opening 11, and a plurality of metal contacts 12 and 13 arranged on the front and rear sides of the window opening 11 and electrically connected with printed circuits (not shown) subject to a predetermined layout for the connection of the memory card connector 2 and the connecting terminal set 3. [0017]Referring to FIGS. 1 and 3, the memory card connector 2 is a multi-in-one card connector mounted on the connecting substrate 1 over the window opening 11, having an electrically insulative connector body 21 and multiple sets of metal terminals 22 arranged in the electrically insulative connector body 21 for the connection of MS (Memory Stick), XD (Extreme Digital), MMC (MultiMedia Card), or SD (SecureDigital Memory Card). The bonding ends 221 and 222 of the metal terminals 22 are respectively soldered to the metal contacts 12 of the connecting substrate 1 to electrically connecting the inserted memory card to the printed circuits of the connecting substrate 1. [0018]The connecting terminal set 3 comprises an electrically insulative terminal holder block 31 and a plurality of metal terminals 32 mounted in the electrically insulative terminal holder block 31. The metal terminals 32 each have a rear bonding end 321 and a front bonding end 322. The rear bonding ends 321 of the metal terminals 32 are respectively soldered to the metal contacts 13 of the connecting substrate 1. The front bonding ends 322 are respectively soldered to respective metal contacts 42 of the PC board 4. [0019]Referring to FIGS. 1.about.3, the PC board 4 has arranged thereon a circuit layout carrying a controller (control chip), activator, and other necessary electronic devices (because the circuit layout is of the known art and not within the scope of the claims of the present invention, no further detailed description in this regard is necessary). The PC board 4 has an electric connector 41 disposed at one end for connection to a notebook computer or any of a variety of other electronic apparatus. The electric connector 41 comprises an electrically insulative housing 411 and a plurality of metal terminals 413 mounted in respective terminal slots 412 in the electrically insulative housing 411 and electrically soldered to the PC board 4. The PC board 4 further has a plurality of metal contacts 42 to which the front bonding ends 322 of the metal terminals 32 are soldered. [0020]Referring to FIGS. 4.about.7 and FIG. 1 again, the electrically insulative housing of the memory card adapter is comprised of a rectangular frame 51 and two cover shells 52. The rectangular frame 51 has two accommodation spaces 511 and 512 that accommodate the connecting substrate 1 and the PC board 4 respectively, keeping the receiving side of the memory card connector 2 and the connection side of the electric connector 41 respectively protruded over two opposite ends of the electrically insulative housing. The two cover shells 52 are respectively fastened to the top and bottom sides of the rectangular frame 51 and covered over the connecting substrate 1 and the PC board 4.
