Move sideways, so that the plurality of first metal contacts 621 and the plurality of second metal contacts 631 provided on the surface of the SIM card 62 and the SD card 63 respectively form an electrical connection with the first docking portions 411 and the second docking portions 511 on the first terminal set 4 and the second terminal set 5, and then the electronic signal is transmitted to the preset circuit board through the first welding portions 412 and the second welding portions 512.

In addition, the aforementioned insulating base body 1 is provided with a plurality of first fixing holes 14 and at least one second fixing hole 15 at the periphery thereof, and the first fixing holes 14 and each of the second fixing holes 15 are provided for the corresponding plurality of first fixing columns 22 and at least one second fixing column 23 on the insulating base 2 to be inserted and fixed, and the aforementioned insulating base body 1 is provided with at least one limiting groove 16 at the periphery of the outer side thereof, and the shielding shell is assembled on the outer cover of the insulating base body 1 and the insulating base 2. 7, and a plurality of blocking blocks 24 are provided on the surface of the insulating base 2 corresponding to at least one side of the shielding shell 7 to prevent separation, and a plurality of observation holes 70 are provided on the shielding shell 7 for observing the internal components, and each bend extending on the outer side of the shielding shell 7 has at least one grounding foot 71 welded to the preset circuit board, and a fixed arm 72 is provided at each of the limiting grooves 24 on the periphery of the shielding shell 7 corresponding to the insulating base 2 and extending into the limiting groove 16 for positioning.

Furthermore, the aforementioned sliding assembly 3 further includes a sliding seat 31 inside, and a receiving groove 310 for accommodating a positioning guide rod 32 is recessed in the sliding seat 31, and one end of the positioning guide rod 32 is positioned in a positioning groove 121 recessed on the sliding groove 12, and the other end of the positioning guide rod 32 rotates counterclockwise in the receiving groove 310, and the uppermost end of the receiving groove 310 is the starting point and the end point of the movement of the positioning guide rod 32. The pushing method of the sliding assembly 3 is not the main technical content of the present invention, so its pushing state is not described in detail. By pushing the sliding assembly 3, the card tray 6 is half-inserted into the docking space 10, and the card tray 6, the SIM card 62 and the SD card 63 can be taken out.

Furthermore, an elastic member 33 is accommodated between the sliding seat 31 and the sliding groove 12, and a limit strip 13 is protruded between the sliding groove 12 and the docking space 10 to limit the sliding seat 31, and the sliding seat 31 is further provided with a positioning protrusion 311 on one side facing the docking space 10, and a supporting wall 312 is protruded from the end of the sliding seat 31, and the interference of the sliding assembly 3 is utilized to enable the sliding seat 31 to move toward the bottom side of the docking space 10 when the card tray 6 is inserted into the docking space 10.

The inclined surface 66 and a card removal slot 67 are provided. The function of the guiding inclined surface 66 is to prevent the upper and lower frame walls from hooking onto the first conductive terminal 41 or the second conductive terminal 51 and causing the terminal to collapse (or collapse PIN) when the card tray 6 is withdrawn when the card tray 6 is inserted into the docking space 10 and engaged with the sliding assembly 3 for positioning and disengagement when the card tray 6 is not inserted. Therefore, the guiding inclined surface 66 is used to guide and avoid the aforementioned phenomenon.

Furthermore, the at least one buffer groove 640 has the function that when the SIM card 62 or the SD card 63 is placed in the card insertion space 60, the side of the SIM card 62 or the SD card 63 corresponding to the abutting ridge 641 will push the abutting ridge 641, so that the abutting ridge 641 is elastically deformed and abuts against the side of the SIM card 62 or the SD card 63. The at least one buffer groove 640 provides a buffer space when the supporting flange 641 is elastically deformed. The size of the card tray 6 is designed to be relatively thin and light, and the stress that can be borne is not large. The at least one buffer groove 640 reduces the stress when the supporting flange 641 is elastically deformed, so as to avoid the card tray 6 from breaking due to the inability to withstand the stress when the card is placed.

Furthermore, the preferred implementation specification of the SIM card 62 is Micro SIM Card, and the preferred implementation specification of the SD card 63 is Micro SD Card.

The insulating seat 1 and the insulating base 2 have an inner wall at one side of the connecting space 10 away from the sliding groove 12 and an inner wall surface at the bottom where the card holder 6 is inserted. When the buckle groove 65 of the card holder 6 is inserted into the positioning protrusion 311 of the sliding assembly 3, the card holder 6 is supported against the inner wall of the insulating seat 1 and the insulating base 2 to generate stress in a direction away from the positioning protrusion 311, and the side of the card holder 6 is used to prevent the card holder 6 from being stuck. The provision of the clearance groove 17 eliminates the stress and allows the corresponding supporting side of the card tray 6 to have a larger gap to prevent the card tray 6 from getting stuck or being unsmooth during the insertion and removal process. In addition, the clearance groove 17 provided on the bottom side can allow the inner side wall of the bottom end of the insulating seat 1 to deform while still being sufficient to provide the necessary stroke for the card tray 6 to be inserted into the docking space 10, thereby preventing the card tray 6 from getting stuck or being unsmooth during the insertion and removal process.

In addition, the above-mentioned insulating seat body 1 and the connecting space 10 in the insulating base 2 are provided with anti-fool ribs 18 on both sides of the card tray 6 insertion entrance, and the two sides of the card tray 6 are provided with slide grooves 68 for the two anti-fool ribs 18 to slide into and position. The two anti-fool ribs 18 are positioned in coordination with the positions of the two slide grooves 68 to prevent the card tray 6 from being blocked and unable to be inserted when the upper and lower sides are reversely inserted, thereby achieving an anti-fool effect.

Please refer to Figures 4, 5, 6, and 7, which are a three-dimensional exploded view, another three-dimensional exploded view, a top view and a bottom view of the card tray of the present invention. It can be clearly seen from the figures that the first terminal set 4 is composed of nine first conductive terminals 41, each of which is bent and arched toward the docking space 10 to form the first docking portions 411 that are supported on the first metal contacts 621 of the SIM card 62, and the first docking portions 411 extend to one side through a plurality of bends to form the first welding portions 412, and the second terminal set 5 is composed of nine first conductive terminals 41. The second conductive terminals 51 are respectively bent and arched toward the docking space 10 to form the second docking portions 511 that are supported on the second metal contacts 631 of the SD card 63, and the second docking portions 511 are extended to one side through a plurality of bends to form the second welding portions 512, and the supporting terminal 52 is bent downward corresponding to the sliding assembly 3 to provide the top side of the positioning guide rod 32 for abutment and positioning, so that the positioning guide rod 32 is pressed by the supporting terminal 52 to prevent it from falling off from the positioning groove 121 and the receiving groove 310.

From the disclosure of the above-mentioned Figures 1 to 7, it can be understood that the invention is mainly aimed at the card insertion space 60 of the card tray 6 received in the docking space 10 formed in the dual-card connector, and the card insertion space 60 is divided into two by the partition 61, thereby simultaneously inserting a Micro SIM card 62 and a Micro SIM card 63. The SD card 63 is received in the card tray 6, and the SIM card 62 and the SD card 63 are inserted into the docking space 10 through the card tray 6, and the nine first conductive terminals 41 of the first terminal group 4 and the nine second conductive terminals 51 of the second terminal group 5 are elastically supported on the surfaces of the SIM card 62 and the SD card 63 to form electrical connection and positioning, so as to achieve the situation that the size of the dual-card connector is not changed and the SIM card 62 and the SD card 63 can be read at the same time, with the main feature of saving the cost of the dual-card connector space.
