Description
Technical Field
[0001] The invention belongs to the technical field of electronic card connectors, and in particular relates to a miniaturized ultra-thin laminated double-card tray. Background Art
[0002] As mobile phones become thinner and lighter, SIM cards are also becoming smaller, thinner, and miniaturized and ultra-thin SIM card connectors are becoming mainstream. However, due to work requirements, a single SIM card cannot meet user needs. Therefore, in order to improve the applicability and versatility of mobile phones, a multi-slot card tray structure has gradually emerged. In the traditional multi-slot card tray structure, multiple card slots are designed to be flat, which increases the plane volume of the card tray and occupies a large area of the mobile phone. Later, R&D personnel stacked multiple card slots up and down, and developed it into the later laminated card tray structure. The laminated card tray not only meets user needs in terms of card capacity, but also realizes a miniaturized design in the card tray size, which contributes space for the size expansion of other parts of the mobile phone.
[0003] For stacked card trays, if the size and profile of the cards placed in the upper and lower card slots are different, the shape difference of the two cards can be directly used to achieve the bottom support of the upper and lower chucks, without the need to set an additional middle support plate between the upper and lower card slots of the card tray, such as a stacked multi-selection SIM card holder disclosed in the prior art with patent publication number CN117335182A. However, with the rapid development of 5G, the cards used in mobile communication terminals on the market are gradually becoming more unified and miniaturized, and most of them only use one type of card, namely the nano SIM card. If the size and profile of the cards placed in the upper and lower card slots are the same, it will bring new changes to the structural design of the card tray, but no matter how it changes, it is impossible to achieve a win-win situation in terms of the thickness of the card tray and the overall size of the card tray. For example, in the prior art, patent publication number CN104183936B discloses a dual-card holder and a mobile handheld device using the same, in which an annular support flange is provided inside the card tray, and the space above the annular support flange on the card tray forms a first recess for placing a first card, and the space below the annular support flange on the card tray forms a second recess for placing a second card, the upper surface of the annular support flange supports the first electronic card, and the lower surface of the annular support flange supports the second electronic card; another example is a laminated two-in-one card tray disclosed in patent publication number CN213584258U in the prior art, in which an intermediate partition is provided between the upper and lower card slots of the card tray, and the intermediate partition is used to support the cards in the two card slots; both of these card tray structures sacrifice the thickness of the card tray, thereby increasing the thickness of the card tray.
[0004] On the other hand, the prior art patent publication number CN209017029U discloses a card tray and an electronic device, which vertically distributes two upper and lower card slots with the same contour, that is, the long edge of the upper card slot is set in the front-to-back direction, and the long edge of the lower card slot is set in the left-to-right direction. Although this solves the problem of the thickness of the card tray, the left-to-right length dimension of the entire card tray is increased, thereby increasing the plane area of the card tray.
[0005] Therefore, it is necessary to provide a miniaturized ultra-thin laminated dual-card tray to solve the technical problem that laminated card trays with the same outline size of card slots cannot achieve a win-win situation in terms of tray thickness and tray size. Summary of the invention
[0006] The main purpose of the present invention is to provide a miniaturized ultra-thin laminated dual-card tray, which can achieve a win-win situation in terms of tray thickness and tray size.
[0007] The present invention achieves the above-mentioned purpose through the following technical scheme: a miniaturized ultra-thin laminated dual-card tray, comprising a first card slot arranged on the upper surface for placing a first electronic card, and a second card slot arranged on the lower surface for placing a second electronic card and stacked up and down with the first card slot, the first electronic card placed in the first card slot and the second electronic card placed in the second card slot are stacked up and down and their surfaces are in contact with each other; the first card slot and the second card slot have the same contour shape and the short side center line of the first card slot is arranged at an angle to the short side center line of the second card slot, the first card slot is formed by being surrounded by a first enclosure, and the second card slot is formed by being surrounded by a second enclosure, the lower surface of the first enclosure is partially exposed above the second card slot to support the second electronic card, and the upper surface of the second enclosure is partially exposed below the first card slot to support the first electronic card.
[0008] Furthermore, the first enclosure and the second enclosure are stacked, and notches that cooperate with the holder for positioning are symmetrically arranged on the outer sides of the first enclosure and the second enclosure.
[0009] Furthermore, the first electronic card is a SIM card or a memory card, and the second electronic card is a SIM card or a memory card.
[0010] Further, the thickness of the first card slot is consistent with the thickness of the first electronic card, and the thickness of the second card slot is consistent with the thickness of the second electronic card.
[0011] Furthermore, the first card slot and the second card slot are centrosymmetric with respect to a geometric center line of a short side of the miniaturized ultra-thin laminated dual-card tray.
[0012] Furthermore, the first enclosure and the second enclosure are stacked up and down and staggered left and right.
[0013] Compared with the prior art, the beneficial effects of the miniaturized ultra-thin laminated dual-card tray of the present invention are as follows: (1) the first card slot on the upper surface of the laminated dual-card tray and the second card slot on the lower surface are horizontally rotated in opposite directions by a small angle to achieve angular misalignment, so that the first enclosure around the first card slot on the upper surface and the second enclosure around the second card slot on the lower surface have non-overlapping areas, and these non-overlapping parts are used as the support structure at the bottom of the first card slot on the upper surface and the support structure at the top of the second card slot on the lower surface, respectively, thereby eliminating the original support structure in the middle of the double-layer laminated card tray, thereby achieving the overall thinning of the card tray; (2) the first card slot and the second card slot are symmetrical about the geometric center line of the short side of the laminated dual-card tray, that is, the first card slot is tilted to the left (or right) at a certain angle, and at the same time, the second card slot is tilted to the opposite direction, that is, the right (or left) at the same angle. At this time, not only is the thickness of the laminated dual-card tray the thinnest, but the length and width of the laminated dual-card tray are also the smallest. At this time, a miniaturized and ultra-thin laminated dual-card tray can be designed. Therefore, compared with the prior art, the laminated dual-card tray provided by this solution not only reduces the overall thickness of the tray, but also keeps the length and width of the tray to a minimum, and can achieve a win-win situation in both tray thickness and tray size, meeting the needs of miniaturization and ultra-thinness of electronic cards.

[0026] Please refer to Figure 1-Figure 6 The present embodiment is a miniaturized ultra-thin laminated dual-card tray. The laminated dual-card tray 100 includes a first card slot 1 on the upper surface for placing a first electronic card 200, and a second card slot 2 on the lower surface for placing a second electronic card 300 and stacked with the first card slot 1. The first card slot 1 and the second card slot 2 have the same contour shape and the short side center lines of the first card slot 1 and the second card slot 2 are arranged at an angle. The first card slot 1 is formed by surrounding a first enclosure 3, and the second card slot 2 is formed by surrounding a second enclosure 4. A portion of the lower surface of the first enclosure 3 is exposed above the second card slot 2 to support the second electronic card 300, and a portion of the upper surface of the second enclosure 4 is exposed below the first card slot 1 to support the first electronic card 200.
[0027] The stacked dual-card tray 100 is a pull-out frame-type tray, and notches 5 for matching with the card holder are symmetrically arranged on both outer sides of the stacked dual-card tray 100.
[0028] The first electronic card 200 is a SIM card or a memory card, and the second electronic card 300 is a SIM card or a memory card. The first electronic card 200 placed in the first card slot 1 and the second electronic card 300 placed in the second card slot 2 are attached to each other.
[0029] The thickness of the first card slot 1 is consistent with the thickness of the first electronic card 200 , and the thickness of the second card slot 2 is consistent with the thickness of the second electronic card 300 .
[0030] The first card slot 1 and the second card slot 2 are centrally symmetrical about the geometric center line of the short side of the stacked dual card tray 100, that is, the first card slot 1 is inclined at a certain angle to the left (or right), and at the same time, the second card slot 2 is inclined at the same angle to the opposite direction, that is, to the right (or left). At this time, not only the thickness of the stacked dual card tray 100 is the thinnest, but also the length and width of the stacked dual card tray 100 are the smallest. At this time, a miniaturized and ultra-thin stacked dual card tray 100 can be designed.
[0031] The first enclosure 3 and the second enclosure 4 are both frame-type structures. The first enclosure 3 and the second enclosure 4 are stacked up and down and staggered left and right. The first electronic card 200 and the second electronic card 300 are both square structures. The first card slot 1 and the second card slot 2 are respectively shaped like the first electronic card 200 and the second electronic card 300, so the first card slot 1 and the second card slot 2 are both square structures.
[0032] The first enclosure 3 includes a first long side 31 inclined to the right (or left), a first short side 32 connected to the first long side 31 in a circular arc transition and perpendicular to the first long side 31, a second long side 33 connected to the first short side 32 in a circular arc transition and parallel to the first long side, and a second short side 34 connected to the second long side 33 in a circular arc transition and parallel to the first short side.
[0033] The first long side 31 , the first short side 32 , the second long side 33 and the second short side 34 are all sections extending from the center of the side to one of the right angles, which are exposed above the second card slot 2 to support the second electronic card 300 .
[0034] The second enclosure 4 includes a third long side 41 inclined to the left (or right), a third short side 42 connected to the third long side 41 by an arc transition and perpendicular to the third long side 41, a fourth long side 43 connected to the third short side 42 by an arc transition and parallel to the third long side, and a fourth short side 44 connected to the fourth long side 43 by an arc transition and parallel to the third short side.
[0035] The third long side 41 , the third short side 42 , the fourth long side 43 and the fourth short side 44 are all sections extending from one of the right angles to the center of the side, which are exposed below the first card slot 1 to support the first electronic card 200 .
[0036] The second short side 34 is provided with a first latching protrusion 341 cooperating with the first electronic card 200 inside the first card slot 1 , and the fourth short side 44 is provided with a second latching protrusion 441 cooperating with the second electronic card 300 inside the second card slot 2 .
[0037] The present invention relates to a miniaturized ultra-thin laminated dual-card tray. (1) The first card slot 1 on the upper surface of the laminated dual-card tray 100 and the second card slot 2 on the lower surface are horizontally rotated in opposite directions by a small angle to achieve angular misalignment, so that the first enclosure 3 around the first card slot 1 on the upper surface and the second enclosure 4 around the second card slot 2 on the lower surface have non-overlapping areas. These non-overlapping parts are used as the support structure at the bottom of the first card slot 1 on the upper surface and the support structure at the top of the second card slot 2 on the lower surface, respectively, thereby eliminating the need for a support structure in the middle of the original double-layer laminated card tray. Support structure, thereby realizing the thinning of the overall thickness of the laminated dual-card tray 100; (2) the first card slot 1 and the second card slot 2 are symmetrical about the geometric center line of the short side of the laminated dual-card tray 100, that is, the first card slot 1 is tilted to the left (or right) at a certain angle, and at the same time, the second card slot 2 is tilted to the opposite direction, that is, the right (or left) at the same angle. At this time, not only the thickness of the laminated dual-card tray 100 is the thinnest, but also the length and width of the laminated dual-card tray 100 are the smallest. At this time, a miniaturized and ultra-thin laminated dual-card tray 100 can be designed. Therefore, compared with the prior art, the laminated dual-card tray 100 provided by this solution not only thins the overall thickness of the tray, but also can keep the length and width of the tray to the minimum, and can achieve a win-win situation of the tray thickness and tray size at the same time, meeting the requirements of miniaturization and ultra-thinness of electronic cards.
[0038] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
