DETAILED DESCRIPTION

[0022] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or components / elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and are not to be construed as limiting the present invention.

[0023] The following describes a two-in-one card holder according to an embodiment of the present invention with reference to the accompanying drawings.

[0024] Figure 1 This is an exploded view of a two-in-one card holder provided by one embodiment of the present utility model; Figure 2 This is a three-dimensional diagram of an upper user identification module assembly of a two-in-one card holder provided by an embodiment of the present utility model; Figure 3 This is a three-dimensional diagram of a lower user identification module assembly of a two-in-one card holder provided by one embodiment of the present utility model; Figure 4 This is a partial enlarged view of the spring head of the upper terminal of a two-in-one card holder provided by another embodiment of the present invention. Figure 1-4 As shown, the two-in-one card holder includes: a circuit board mainboard 1, a lower user identification module component 2 arranged on the circuit board mainboard 1, and an upper user identification module component 3 connected to the circuit board mainboard 1; wherein, one end of the upper user identification module component 3 is electrically connected to the circuit board mainboard 1 to form a semi-enclosed structure; a plurality of through holes are provided in the middle of the lower user identification module component 2, and a lower terminal 21 protruding upward is embedded in the through hole; a plurality of through holes are provided in the middle of the upper user identification module component 3, and an upper terminal 31 protruding downward is embedded in the through hole.

[0025] Specifically, in the Subscriber Identity Module (SIM), the upper terminals 31 of the upper SIM assembly are simultaneously injection-molded within the mold along with the housing. Compared to conventional housing-assembled structures, this approach and structure improves structural strength while reducing the overall dimensions of the card holder. Similarly, the lower terminals 21 are also injection-molded within the mold along with the lower SIM assembly, achieving the same effect. Furthermore, this approach allows the lower terminals 21 and upper terminals 31 to be embedded within the card holder, preventing deformation of the spring element and PIN breakage during card tray removal.

[0026] According to the two-in-one card holder of the present invention, the structural strength is improved while the external dimensions of the card holder are reduced, and the problem of the spring fragment being pinned can be prevented, thereby improving the reliability of the spring fragment.
