Description

A mobile handheld device with dual-card deck and its application

Technical field:

The invention relates to a dual-card deck and a mobile handheld device for its application.

Background technique:

Due to the limitation of its internal space structure, existing mobile handheld devices are usually in a single-card mode, that is, the electrical connection between the electronic card and the PCB is realized through a single-card holder.

In order to realize the dual-card function, a current method is to arrange two independent single-card card holders side by side horizontally or vertically, but it takes up a lot of space and is difficult to arrange, and the design of the side card outlet of the mobile handheld device is inconvenient, so corresponding Different card holders are provided with bayonet outlets, which affect the appearance and the strength of the whole machine. Another way is to use a double-card holder, but the double-card holder has two card slots, and different electronic cards are set in different card slot cavities. The whole is thicker, and each electronic card needs to be installed and removed separately. , and it is inconvenient to eject the card from the side of the mobile handheld device.

Invention content:

The purpose of the present invention is to provide a dual-card holder, which has a simple structure, is relatively thin overall, and can realize simultaneous loading and unloading of dual electronic cards.

A double-card deck, including a first deck, a second deck, and a card tray, is characterized in that:

The first card holder is provided with a plurality of terminals, and the terminals include a contact end and a welding end protruding downward from the first card holder;

The second deck is opposite to the first deck and located below the first deck, and a slot is formed between the first deck and a number of terminals are also provided on the second deck, and the terminals include a contact terminal and a solder terminal projecting upwardly from the second socket; and

The card holder has a first recess on its upper surface where the first electronic card can be placed, and a second recess on its lower surface that can place the second electronic card. The card holder is arranged in the slot and The first electronic card on the first recess and the second electronic card on the second recess can be respectively electrically connected to the contact terminals on the first card seat and the contact terminals on the second card seat.

The dual-card deck of the present invention can be improved through the following schemes:

It also includes an upper case and a lower case, the first card seat is arranged in the upper case, the second card seat is arranged in the lower case, the upper case and the lower case cooperate with each other so that the first card seat is located The upper part of the second deck is arranged opposite to the upper and lower sides of the second deck.

The right side of the slot forms a slot opening, and the corresponding slot openings on the right side of the upper casing and the lower casing also form openings, and the front and rear sides of the upper casing are respectively provided with slots extending into the slots. The elastic positioning buckles on the front and rear sides, and the front and rear sides of the card holder are respectively provided with gaps for elastic buckling of the positioning buckles.

The card tray is a pull-out tray, and the tray can slide along the slot and freely enter or exit the slot.

The left side of the upper casing forms a stop part that can cooperate with the card tray when the card tray slides into the slot.

The first recess and the second recess communicate with each other.

The card holder is a frame-shaped holder, the inner wall of the frame-shaped holder is provided with an annular support flange, and the annular support flange extends from the inner side wall of the frame-shaped holder to the center of the holder. The space above the annular support flange forms the first recess, and the space on the card support below the annular support flange forms the second recess.

The welding ends of the terminals on the first card holder protrude from the front and rear sides of the first card holder and are close to the slot opening on the right side of the slot, and the welding ends of the terminals on the second card holder Protrudes from the left side of the second card holder and is near the left side of the slot.

The first electronic card is a SIM card, and the second electronic card is a memory card; or both the first electronic card and the second electronic card are SIM cards or memory cards.

Another object of the present invention is to provide a mobile handheld device, the dual-card holder has a simple structure, is relatively thin overall, and can realize simultaneous loading and unloading of dual electronic cards.

A mobile handheld device, comprising at least a shell, and a PCB board arranged in the shell, characterized in that: it also includes the above-mentioned dual-card deck, the welding end on the first deck, and the second deck The soldering ends on the top are respectively electrically connected to the PCB board.

A dual-card card holder or mobile handheld device of the present invention has the following advantages: 1. Simple structure, the first card holder and the second card holder are set up and down opposite to each other and only form one slot, the first electronic card and the second electronic card The card can be inserted into the slot through the same card holder and electrically connected with the first card holder and the second card holder respectively. The design frees up more space. 2. The design of the card outlet on the side of the mobile handheld device is convenient. It only needs to open a card outlet corresponding to the slot that can be arched and the card tray can be inserted and exited, which will not affect the appearance and the strength of the whole machine. 3. The first electronic card and the second electronic card can be inserted or removed at the same time through the card tray, which is faster and more convenient to install and remove.
