As shown in fig. 2 to 4, the supporting base 100 includes a housing 110 and an insulating plate 120, the housing 110 covers the insulating plate 120, and the insulating plate 120 covers the card holder 200. The material of the housing 110 may be a metal material, and the material of the insulating plate 120 may be a solid insulating material such as rubber, plastic, and ceramic.

Specifically, the side of the case 110 extends vertically in a direction approaching the insulating plate 200 to form a first bending arm 1101, a second bending arm 1102, and a third bending arm 1103. The first bending arm 1101 extends to a side away from the card holder 200 to form a fourth bending arm 1104, wherein a sliding slot 1105 is further formed on the fourth bending arm 1104. Insulating plate 120 includes bottom wall 1201 and side wall 1202, wherein bottom wall 1201 and side wall 1202 set up perpendicularly, and both are the integrated into one piece structure.

As shown in fig. 5 to 6, the card holder 200 includes a mounting portion 210, a pushing portion 220 and a blocking plate 230, which may be an integral structure. The mounting portion 210 includes a first side 2101, a second side 2102, and a third side 2103. Wherein, the first side 2101 and the second side 2102 are two sides perpendicular to the pushing portion 220, the first end of the third side 2103 connects the end of the first side 2101 away from the pushing portion 220, the second end of the third side 2103 connects the end of the second side 2102 away from the pushing portion, and the third side 2103 is parallel to the pushing portion 220. The length of the first side 2101 and the second side 2102 is less than the length of the third side 2103, so that the card holder 200 is placed transversely, and the occupied space of the card holder 200 in the longitudinal direction is reduced. Furthermore, the mounting portion 210 further has an accommodating space 2104 formed therein, for example, the first side 2101, the second side 2102 and the third side 2103 are surrounded to form the corresponding accommodating space 2104.

The baffle 230 is transversely embedded in the inner wall of the accommodating space 2104, and divides the accommodating space 2104 to form a first card slot 2104a and a second card slot 2104b for transversely and stacking two cards. For example, the first card slot 2104a and the second card slot 2104b are used for placing nano sim cards, and the card slots are each 12mmx9mm in size. Further, a first protrusion 2105 is disposed on a side wall of the first locking groove 2104a close to the pushing portion 220, wherein the material of the first protrusion 2105 may be an elastic member having a certain deformation capability. For example, it may be a flexible material such as silicone, rubber, and plastic. When first draw-in groove 2104a inserts nano sim card, first bellying 2105 takes place deformation by the extrusion of nano sim card to produce reverse elasticity, support the nano sim card in first draw-in groove 2104a, thereby reach the purpose of closely fixed nano sim card, prevent that the nano sim card from deviating or dropping in the process of inserting or taking out. A first notch 2107 is further formed in a side wall of the first engaging groove 2104a away from the pushing portion 220, wherein the first notch 2107 is formed in a middle area of the side wall. In the card taking process, since the nano sim card is already tightly fixed in the first card slot 2104a, the nano sim card needs to be lifted up through the first notch 2107 and then taken out. The arrangement of the first gap 2107 can avoid the problem that the nano sim card cannot be easily taken out after being tightly propped against the first clamping groove 2104a by the first protruding part 2105, and the convenience of card taking is improved. In addition, in some alternative embodiments, the mounting portion 210, the pushing portion 220, and the blocking plate 230 may also be three separate components, and may be fixedly connected together by plugging, fastening, welding, and the like.

Wherein a partial area of the second terminal lead 400 projects into the second card slot 2104b to form a contact pad. When the second card slot 2104b is inserted into a card, the PCB board 20 is connected to the card of the second card slot 2104b via the second terminal leads 400.

The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Referring to fig. 9 to 10, fig. 9 is a schematic view illustrating a connection structure of the push rod 500, the swing link 600 and the support base 100 in fig. 1, and fig. 10 is a schematic view illustrating a connection structure of the push rod 500 and the swing link 600 in fig. 9.

As shown in fig. 9 to 10, the push rod 500 is disposed in the sliding slot 1105 of the fourth bending arm 1104 and can slide in the sliding slot 1105, wherein the sliding direction is the same as the sliding direction of the card holder 200. The swing link 600 is disposed on a side of the sidewall 1202 near the mounting portion 210, i.e., a spacing region between the sidewall 1202 and the third side edge 2103. Meanwhile, the swing link 600 is disposed opposite to the third side 2103 and is rotatably connected to the bottom wall 1201. Further, a limiting groove 5101 is formed in the first end 510 of the push rod, and one end of the swing rod 600 is disposed in the limiting groove 5101 to limit the moving range of one end of the swing rod 600. One end of the pushing portion 220 is provided with a hole 2201, wherein the hole 2201 corresponds to the position of the second end 520 of the pushing rod, and the hole 2201 is used for guiding and positioning the insertion body. For example, by inserting the striker into the hole 2201, the second end 520 of the push rod is accurately abutted by guiding and positioning the hole 2201, so that the push rod 500 slides in the sliding slot 1105 along the first direction X. When the push rod 500 slides in the sliding slot 1105, because one end of the swing link 600 is in the limiting groove 5101, the push rod 500 can drive the swing link 600 to rotate based on the bottom wall 1201, so that the other end of the swing link 600 rotates to the third side 2103 and pushes the third side 2103, thereby enabling the card holder 200 to slide out of the supporting seat 100. Specifically, the housing 110, the bottom wall 1201 and the swing link 600 are connected together by a fixing member 700, wherein the fixing member 700 also serves as a rotation shaft of the swing link 600, so that the swing link 600 can rotate based on the bottom wall 1201. The fixing member 700 may be a structure such as a bolt, a rivet, and a peg. In addition, the card socket 10 further includes a detection terminal 800, which is disposed at an end of the third bending arm 1103 away from the swing link 600, and is used for detecting whether the card holder 200 is inserted into or pulled out of place.

According to the card socket 10 provided by the embodiment, the first card slot 2104a and the second card slot 2104b are transversely stacked, so that the card socket 10 can support dual-card application, and meanwhile, the occupied space of the card socket 10 in the longitudinal direction is reduced, thereby providing convenience for design and assembly of equipment. Set up first bellying 2105 on first draw-in groove 2104a, solved and be connected between card and the draw-in groove and not closely lead to the card to drop or skew problem, strengthened the fastening nature between card and the draw-in groove, and then guaranteed the normal work of cassette 10. Meanwhile, the first notch 2107 arranged on the first card slot 2104a also avoids the problem that the card cannot be taken out easily after being tightly propped against the first card slot 2104a by the first protruding part 2105, and improves the convenience of card taking.
