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, another perspective three-dimensional exploded view, three-dimensional exploded view and another perspective three-dimensional exploded view of the electrical connector of the present utility model that can accommodate two cards. It can be clearly seen from the figures that the present utility model provides an electrical connector that can accommodate two cards, mainly including 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. 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, the insulating base body 1 has a plurality of first through holes 11, and the insulating base 2 has a plurality of second through holes 21. And one side in the docking space 10 has 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 plurality of first through holes 11 of the insulating base 1 and the plurality of 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 plurality of first conductive terminals 41 and the plurality of second conductive terminals 51 are each bent and arched toward 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, a first welding portion 412 extending outside the insulating base 1 is provided. On one side of each second docking portion 511, a second welding portion 512 extending outside the insulating base 2 is provided. Each first welding portion 412 and each second welding portion 512 are welded to a plurality of contacts (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 1 and the insulating base 2 by an insert molding process.

[0031] A card slot 6 is internally formed with a card placement space 60. The card placement space 60 is divided into two by a partition 61. At least one side of the partition 61 is recessed with a card ejection slot 610. In the two card placement spaces 60, a SIM (Subscriber Identity Module) card 62 and an SD (Secure Digital) card 63 are accommodated and positioned. The card slot 6 is inserted into the docking space 10 and pushed, so that the sliding assembly 3 moves along the sliding slot 12 toward 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 plurality of first docking portions 411 and the plurality of 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 plurality of first welding portions 412 and the plurality of second welding portions 512.

[0032] Furthermore, the preferred implementation specification of the above-mentioned SIM card 62 is a Nano SIM Card, and the preferred implementation specification of the SD card 63 is a Micro SD Card.

[0033] In addition, a plurality of first fixing holes 14 and at least one second fixing hole 15 are provided at the periphery of the insulating base 1. The plurality of 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. Moreover, at least one limiting groove 16 is concavely provided at the outer peripheral edge of the insulating base 1. Then, a shielding shell 7 is assembled and covered outside the insulating base 1 and the insulating base 2. And a plurality of stoppers 24 for preventing detachment are provided on the surface of the insulating base 2 corresponding to at least one side of the shielding shell 7. Further, a plurality of observation holes 70 for observing internal components are provided on the shielding shell 7. And at least one grounding leg 71 welded to the preset circuit board is bent and extended from each outer side of the shielding shell 7. Moreover, a fixing arm 72 extending into the limiting groove 16 for positioning is provided at the periphery of the shielding shell 7 corresponding to each limiting groove 24 of the insulating base 2.

[0034] Furthermore, the sliding assembly 3 further includes a sliding seat 31 inside. And a receiving groove 310 for receiving a positioning guide rod 32 is concavely provided in the sliding seat 31. One end of the positioning guide rod 32 is positioned in a positioning groove 121 concavely provided 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 ending point of the movement stroke of the positioning guide rod 32. And the pushing mode of the sliding assembly 3 is not the main technical content of the present invention, so the pushing state is not described in detail. And by pushing of the sliding assembly 3, the card tray 6 is in a state of being 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.

[0035] Moreover, 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 is convexly provided between the sliding groove 12 and the docking space 10. And a positioning convex block 311 is further provided on one side of the sliding seat 31 facing the docking space 10. And a resisting wall 312 is convexly provided at the end of the sliding seat 31 after turning. And 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.

[0036] In addition, the card holder 6 is provided with a frame 64 at each of the two long sides corresponding to the SIM card 62 and the SD card 63. At least one buffer groove 640 and at least one abutting flange 641 are provided on the relative inner sides of the two frames 64. A buckle groove 65 is provided at the outer edge of one of the two frames 64 corresponding to the positioning protrusion 311 of the sliding assembly 3. The card holder 6 is provided with a guiding inclined surface 66 and a card-taking slot 67 at each of the two short sides corresponding to the SIM card 62 or the SD card 63. The function of the guiding inclined surface 66 is to prevent the upper and lower frame walls from catching the first conductive terminal 41 or the second conductive terminal 51 when the card holder 6 is withdrawn, resulting in terminal collapse (or PIN collapse) when the card holder 6 is inserted into the docking space 10 and engaged with and disengaged from the sliding assembly 3. Therefore, the guiding inclined surface 66 is used to guide and avoid the above-mentioned phenomenon.

[0037] The function of the card ejection slot 610 on the partition 61 is that when one of the SIM card 62 or the SD card 63 exits from the card placement space 60, the card ejection slot 610 can push the SIM card 62 or the SD card 63 on the other side to exit, so as to complete the card ejection operation of the SIM card 62 and the SD card 63.

[0038] 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 the abutting flange 641 is elastically deformed and abuts against the side of the SIM card 62 or the SD card 63 for fixation. 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 holder 6 is designed to be thinner and lighter, and the stress it can withstand is not large. Furthermore, the stress during the elastic deformation of the abutting flange 641 is reduced by the at least one buffer groove 640, so as to achieve the effect of preventing the card holder 6 from breaking due to inability to withstand the stress when placing the card.

[0039] The above-mentioned insulating seat body 1 and the insulating base 2 have an escape groove 17 formed on the inner wall of the docking space 10 away from the sliding groove 12 and on 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 inserted into the positioning protrusion 311 of the sliding component 3, the card tray 6 is pressed against the inner side walls of the insulating seat body 1 and the insulating base 2 to generate stress in the direction away from the positioning protrusion 311. The stress is eliminated by the setting of the side escape groove 17, so that the corresponding abutting side of the card tray 6 can have a larger gap to prevent the card tray 6 from getting stuck or being unsmooth during the plugging and unplugging process. In addition, the escape groove 17 set on the bottom side can make the inner side wall of the bottom end of the insulating seat body 1 deform, which is still sufficient to provide the necessary stroke for the card tray 6 to be inserted into the docking space 10, and can also prevent the card tray 6 from getting stuck or being unsmooth during the plugging and unplugging process.

[0040] In addition, the docking space 10 between the insulating seat body 1 and the insulating base 2 is provided with anti-foolproof flanges 18 on both sides of the insertion entrance of the card tray 6, and the two sides of the card tray 6 are provided with sliding grooves 68 for the two anti-foolproof flanges 18 to slide into and position. The two anti-foolproof flanges 18 are positioned in coordination with the positions of the two sliding 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-foolproof effect.

[0041] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, there are respectively a three-dimensional exploded view, a three-dimensional exploded view from another perspective, a top view and a bottom view of the card tray of the utility model electrical connector. It can be clearly seen from the figure that the first terminal group 4 is composed of seven first conductive terminals 41, and the plurality of first conductive terminals 41 are bent and arched toward the docking space 10 to form the plurality of first docking portions 411 that are supported on the plurality of first metal contacts 621 of the SIM card 62, and the plurality of first docking portions 411 extend to one side through a plurality of bends to form the plurality of first welding portions 412, and the second terminal group 5 is composed of nine second conductive terminals 5 1 and a holding terminal 52, the plurality of second conductive terminals 51 are each bent and arched toward the docking space 10 to form the plurality of second docking portions 511 that are held against the plurality of second metal contacts 631 of the SD card 63, and the plurality of second docking portions 511 extend to one side through a plurality of bends to form the plurality of second welding portions 512, and the holding terminal 52 is bent downwardly corresponding to the sliding component 3 so as to be held and positioned by the top side of the positioning guide rod 32, so that the positioning guide rod 32 is pressed by the holding terminal 52 so as not to fall off from the positioning groove 121 and the accommodating groove 310.

[0042] By the above Figures 1 to 7From the disclosure above, it can be understood that the present utility model mainly aims at the docking space 10 formed between the insulating base 1 and the insulating pedestal 2, and a stacked card seat structure is provided in the card placement space 60 of the card holder 6 received in the docking space 10, where the card placement space 60 is divided into two by the partition 61. Then, a Nano SIM card 62 with different numbers of terminals and a Micro SD card are simultaneously received and electrically connected to the corresponding first terminal group 4 and second terminal group 5 in the insulating base 1 and the insulating pedestal 2 respectively, so as to transfer the electronic data of the two kinds of cards simultaneously in a preset circuit board, thereby reducing the processing cost for reading the two kinds of data on the preset circuit board, and reducing the space for receiving the cards by the stacked structure as the main feature.

[0043] The above description is only a preferred embodiment of the present utility model, and thus does 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 equally included in the patent scope of the present utility model, and are hereby clarified.
