Detailed implementation manners
[0027] Please refer to Figures 1 to 5 as shown, which are respectively the three-dimensional external view, three-dimensional exploded view, three-dimensional exploded view from another perspective, three-dimensional exploded view of the dual card connector and three-dimensional exploded view from another perspective of the card holder structure of the present utility model combined with the dual card connector. It can be clearly seen from the figures that the card holder structure of the present utility model combined with the dual card connector mainly includes an insulating base body 1, an insulating base 2, a sliding assembly 3, a first terminal group 4, a second terminal group 5, a card holder 6 and a shielding housing 7, and the connection relationships of the foregoing components are as follows:
[0028] The insulating base 2 is assembled on the top side of the insulating base body 1, and a docking space 10 is formed therebetween. Further, a plurality of first through holes 11 are provided in the insulating base body 1, and a plurality of second through holes 21 are provided in the insulating base 2. And one side in the docking space 10 is provided with a sliding groove 12 for accommodating and moving the sliding assembly 3.
[0029] The first terminal group 4 and the second terminal group 5 are respectively assembled in the first through holes 11 of the insulating base body 1 and the second through holes 21 of the insulating base 2. The first terminal group 4 includes a plurality of first conductive terminals 41, and the second terminal group 5 includes a plurality of second conductive terminals 51. The first conductive terminals 41 and the second conductive terminals 51 are each bent and arched towards the docking space 10 to form a first docking portion 411 and a second docking portion 511. On one side of each first docking portion 411, there is a first welding portion 412 extending out of the insulating base body 1. On one side of each second docking portion 511, there is a second welding portion 512 extending out of the insulating base 2. Each first welding portion 412 and each second welding portion 512 are welded to a plurality of contact points (not shown in the figure) of a preset circuit board (not shown in the figure).
[0030] Furthermore, in the preferred embodiments of the above-mentioned first terminal group 4 and second terminal group 5, they are combined with the insulating base body 1 and the insulating base 2 through an insert molding process.
[0031] An accommodating space 60 is formed inside the card holder 6. The accommodating space 60 is divided into two by a partition 61. In the two accommodating spaces 60, a SIM (Subscriber Identity Module) card 62 and an SD (Secure Digital) card 63 are accommodated and positioned. The card holder 6 is inserted into the docking space 10 and pushed, so that the sliding assembly 3 moves along the sliding groove 12 towards the bottom side. As a result, a plurality of first metal contacts 621 and a plurality of second metal contacts 631 provided on the surfaces of the SIM card 62 and the SD card 63 respectively form electrical connections with the first docking portions 411 and the second docking portions 511 on the first terminal group 4 and the second terminal group 5. Then, the electronic signals are transmitted into the preset circuit board through the first welding portions 412 and the second welding portions 512.
[0032] In addition, a plurality of first fixing holes 14 and at least one second fixing hole 15 are provided at the peripheral edge of the aforementioned insulating base body 1. The first fixing holes 14 and each second fixing hole 15 are for a plurality of corresponding first fixing posts 22 and at least one second fixing post 23 on the insulating base 2 to pass through and be fixed. At least one limiting groove 16 is recessed at the outer peripheral edge of the aforementioned insulating base body 1. The shielding housing 7 is assembled and covered outside the insulating base body 1 and the insulating base 2. On the surface of the insulating base 2 corresponding to at least one side of the shielding housing 7, there are a plurality of stoppers 24 to prevent detachment. A plurality of observation holes 70 for observing the internal components are provided on the shielding housing 7. At least one grounding leg 71 welded to the preset circuit board is bent and extended on the outer side of the shielding housing 7. At the peripheral edge of the shielding housing 7 corresponding to each limiting groove 24 of the insulating base 2, there is a fixing arm 72 extending into the limiting groove 16 for positioning.
[0033] Furthermore, the sliding assembly 3 further includes a sliding seat 31 therein, and a receiving groove 310 for receiving a positioning guide rod 32 is recessed in the sliding seat 31. One end of the positioning guide rod 32 is positioned in a positioning groove 121 recessed in the sliding groove 12, and the other end of the positioning guide rod 32 rotates counterclockwise in the receiving groove 310. The uppermost end of the receiving groove 310 is the starting point and the ending point of the movement stroke 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 the pushing state thereof will not be described in detail. By pushing the sliding assembly 3, the card tray 6 is semi-inserted into the docking space 10, and then the card tray 6, the SIM card 62 and the SD card 63 can be taken out.
[0034] Furthermore, an elastic member 33 is accommodated between the sliding seat 31 and the sliding groove 12, and a limiting strip 13 for limiting the sliding seat 31 protrudes between the sliding groove 12 and the docking space 10. A positioning protrusion 311 is further provided on one side of the sliding seat 31 facing the docking space 10, and a resisting wall 312 protrudes from the end of the sliding seat 31 in a turning manner. When the card tray 6 is inserted into the docking space 10 by the interference of the sliding assembly 3, the sliding seat 31 is pushed to move towards the bottom side of the docking space 10.
[0035] In addition, outer frames 64 are provided on both long sides of the card tray 6 corresponding to the SIM card 62 and the SD card 63. At least one buffer groove 640 and at least one resisting flange 641 are provided on the relative inner sides of the two outer frames 64. A buckle groove 65 is provided on the outer edge of one of the two outer frames 64 corresponding to the positioning protrusion 311 of the sliding assembly 3. Guide inclined surfaces 66 and card-taking grooves 67 are provided on both short sides of the card tray 6 corresponding to the SIM card 62 or the SD card 63. The function of the guide inclined surface 66 is to prevent the upper and lower frame walls of the card tray 6 from catching the first conductive terminal 41 or the second conductive terminal 51 and causing terminal collapse (or called PIN collapse) when the card tray 6 is inserted into the docking space 10 and engaged and disengaged with the sliding assembly 3 when the SIM card 62 or the SD card 63 is not inserted into the card tray 6. Therefore, the above-mentioned phenomenon is avoided by guiding through the guide inclined surface 66.
[0036] Furthermore, the function of the at least one buffer groove 640 is that when the SIM card 62 or the SD card 63 is respectively placed in the card placement space 60, one side of the SIM card 62 or the SD card 63 corresponding to the abutting flange 641 will push the abutting flange 641, so that after the abutting flange 641 is elastically deformed, it abuts against the side of the SIM card 62 or the SD card 63 for fixation. And the at least one buffer groove 640 will provide a buffer space for the elastic deformation of the abutting flange 641. Therefore, the size of the card tray 6 is designed to be thinner and lighter, and the stress that can be borne is not large. Furthermore, the stress during the elastic deformation of the abutting flange 641 is slowed down by the at least one buffer groove 640, so as to achieve the effect of preventing the card tray 6 from breaking due to being unable to bear the stress when placing the card.
[0037] Furthermore, the preferred implementation specification of the above SIM card 62 is Micro SIM Card, and the preferred implementation specification of the SD card 63 is Micro SD Card.
[0038] A relief groove 17 is respectively formed at the inner wall of the docking space 10 in the insulating base 1 and the insulating base 2 away from the sliding groove 12 and at the inner wall surface of the bottom side where the card tray 6 is inserted. When the buckle groove 65 of the card tray 6 is engaged with the positioning protrusion 311 of the sliding component 3, the card tray 6 generates stress in the direction away from the positioning protrusion 311 and abuts against the inner side walls of the insulating base 1 and the insulating base 2. And the stress is eliminated by the setting of the relief groove 17 on the side, so that a larger gap can be provided on the corresponding abutting side of the card tray 6 to prevent the card tray 6 from being stuck or not smooth during the process of plugging and unplugging. In addition, the relief groove 17 provided on the bottom side can still provide the necessary stroke for the card tray 6 to be inserted into the docking space 10 when the inner bottom side wall of the insulating base 1 is deformed, and similarly, it can prevent the card tray 6 from being stuck or not smooth during the process of plugging and unplugging.
[0039] In addition, anti-fooling flanges 18 are respectively provided at both sides of the docking space 10 in the insulating base 1 and the insulating base 2 for inserting the card tray 6, and sliding grooves 68 for the two anti-fooling flanges 18 to slide into and be positioned are respectively provided at both sides of the card tray 6. The two anti-fooling flanges 18 are used to cooperate with the positions of the two sliding grooves 68 for positioning to prevent the card tray 6 from being blocked and unable to be inserted when being inserted in the reverse direction on the upper and lower sides, thereby achieving the anti-fooling effect.
[0040] Please refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 7As shown, they are respectively the three-dimensional exploded view, the three-dimensional exploded view from another perspective, the top view and the bottom view of the card tray of the dual-card connector of the present utility model. It can be clearly seen from the figure that the first terminal group 4 is composed of nine first conductive terminals 41. Each of these first conductive terminals 41 bends and arches towards the docking space 10 to form first docking portions 411 that abut against the first metal contacts 621 of the SIM card 62. And these first docking portions 411 extend to one side and form these first welding portions 412 through multiple bends. And the second terminal group 5 is composed of nine second conductive terminals 51 and a holding terminal 52. Each of these second conductive terminals 51 bends and arches towards the docking space 10 to form second docking portions 511 that abut against the second metal contacts 631 of the SD card 63. And these second docking portions 511 extend to one side and form these second welding portions 512 through multiple bends. And the holding terminal 52 bends downward corresponding to the sliding component 3 for the top side of the positioning guide rod 32 to abut and be positioned, so as to prevent the positioning guide rod 32 from falling off from the positioning groove 121 and the accommodating groove 310 by pressing with the holding terminal 52.
[0041] By the above Figures 1 to 7 disclosure, it can be understood that the main feature of the present utility model is that a stacked card seat structure is provided in the card placement space 60 of the card tray 6 accommodated in the docking space 10 formed in the dual-card connector, and the card placement space 60 is divided into two by the partition 61. Then, a Micro SIM card 62 and a Micro SD card 63 are simultaneously accommodated 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 elastically abut against the surfaces of the SIM card 62 and the SD card 63 to form electrical connection and positioning, so as to read the SIM card 62 and the SD card 63 simultaneously without changing the size of the dual-card connector, and the main feature is to save the cost of the space of the dual-card connector.
[0042] The above are only the preferred embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Therefore, all simple modifications and equivalent structural changes made by using the content of the specification and drawings of the present utility model should be included in the patent scope of the present utility model by the same token, and are hereby stated.
