Description

Wafer card holder

The present invention relates to a wafer card fixing device, and more particularly to a wafer card fixing device applied to a portable electronic device.

In recent years, surface wafer cards with integrated circuits have been widely used in electronic devices to enhance or increase the performance of electronic devices, such as a subscriber identification module card (hereinafter referred to as a SIM card) installed in a mobile phone, and stored therein. There is necessary information for operating a mobile phone, and personal information about the user is recorded. By replacing the SIM card, a mobile phone can be used by multiple users.

The SIM card of the conventional one is generally placed in one of the slots of the mobile phone. When the SIM card is received in the card slot, the integrated circuit on the SIM card is connected to the circuit board of the mobile phone by a connector. At the same time, the SIM card is partially exposed to the card slot. When the SIM card needs to be replaced, the user directly presses the SIM card to expose the portion outside the card slot, and the user and the SIM card The friction between the SIM cards is slipped out of the card slot.

Since the portion of the SIM card exposed to the card slot is generally small, it is difficult for the user to press the SIM card. Therefore, friction between the user and the SIM card is less likely to occur, and it is difficult to drive the SIM by the friction. The card slides out of the card slot.

In view of the above, it is necessary to provide a wafer card holding device that can facilitate the removal of a wafer card.

A wafer card fixing device includes a combination body, a casing and a screw. The combination body is disposed on the casing. The coupling body defines a card slot for accommodating the wafer card therein. The wafer card is fixed. The device further includes a sliding body, a gap is formed in the sliding body, and a matching hole is formed in the housing. The stud first passes through the notch and then is screwed into the matching hole, thereby sliding the sliding body The sliding body includes a resisting portion and a triggering portion. When the triggering portion slides, the resisting portion abuts the wafer card and slides out of the card slot.

Compared with the prior art, the wafer card fixing device drives the wafer card to slide out of the card slot by the sliding of the trigger portion, so that the wafer card can be easily slipped out of the card slot.

A preferred embodiment of the present invention discloses a wafer card securing device suitable for use in a portable electronic device such as a mobile phone. In the present embodiment, the wafer card fixing device will be described by taking a mobile phone as an example.

Referring to FIG. 1 and FIG. 2 , the wafer card fixing device 100 includes a housing 10 , a combined body 20 , a sliding body 30 , and a screw 40 . A chip card 50 (such as a SIM card, a memory card) is fixed to the casing 10 by the combination body 20, and the chip card 50 is connected to the connector 22 of the combination body 20 by A circuit board (not shown) provides electrical connection.

The housing 10 is part of a mobile phone housing and is generally cuboid. The lower half of the casing 10 defines a rectangular receiving cavity 12 for accommodating the battery, and the accommodating cavity 12 is surrounded by the surrounding wall 14. A fitting hole 16 is defined in the upper half of the housing 10. In this embodiment, the matching hole 16 is a threaded hole, and the matching hole 16 is used for fixing the sliding body 30.

Referring to FIG. 3 , the combined body 20 is a square cavity with an open end, and includes an upper wall 21 , a lower wall 22 , a first sidewall 23 , a second sidewall 24 , and a third sidewall 25 . The lower wall 22 is a wall surface of the combined body 20 facing the casing 10, and the upper wall 21 is disposed opposite to the lower wall 22. The first sidewall 23, the second sidewall 24, and the third sidewall 25 are disposed between the upper wall 21 and the lower wall 22, and the first sidewall 23 is opposite to the second sidewall 24. Both ends of the side wall 25 are connected to the first side wall 23 and the second side wall 24, respectively.

The upper wall 21, the lower wall 22, the first side wall 23, the second side wall 24 and the third side wall 25 define a card slot 26, and an opening 27 is formed at one end of the third side wall 25. The card slot 26 is adapted to receive the wafer card 50, and the wafer card 50 enters the card slot 26 through the opening 27.

The lower wall 22 defines a square through hole 222 adjacent to one end of the third side wall 25. The through hole 222 functions to: when the wafer card 50 is received in the card slot 26, the sliding body 30 is formed by the through hole The 222 extends into the card slot 26 to resist the wafer card 50 (as shown in FIG. 4).

The sliding body 30 has a substantially rectangular plate shape and includes a flat plate portion 32. The two ends of the flat plate portion 32 are respectively bent to form a resisting portion 34 and a trigger portion 36. The abutting portion 34 is for resisting the wafer card 50. In the embodiment, the abutting portion 34 is a flap formed by bending one end of the flat plate portion 32. The triggering portion 36 is configured to trigger the slider 30 to slide out of the slot 26 . In the embodiment, the trigger portion 36 is a hook that is bent by the other end of the flat portion 32 . The sliding body 30 defines an elliptical notch 38 at one end of the flat portion 32 adjacent to the abutting portion 34. The notch 38 is opened corresponding to the matching hole 16.

The screw 40 includes a nut 42 and a stud 44 extending from the nut 42. The stud 44 has a cross-sectional dimension that is less than the cross-sectional dimension of the indentation 38. A screw 40 is used to slidably mount the slider 30 to the housing 10.

Referring to FIG. 5 and FIG. 6 , when the wafer card fixing device 100 is assembled, the sliding body 30 is first placed on the housing 10 , and the notch 38 is aligned with the matching hole 16 , and then the screw is inserted. After the post 44 passes through the notch 38, it is screwed into the fitting hole 16. At this time, since the cross-sectional dimension of the stud 44 is smaller than the cross-sectional dimension of the notch 38, the stud 44 and the flat portion 32 are at the level. There is a gap in the direction, and the nut 42 and the sliding body 30 are kept in a vertical direction, so that the sliding body 30 is slidably fitted on the casing 10; then, the combined body 20 is fixed The splicing portion 34 of the sliding body 30 extends into the card slot 26 to complete the assembly of the wafer card 50 holding device.

When the chip card 50 is mounted, one end of the chip card 50 enters the card slot 26 through the opening 27, and the wafer card 50 enters one end of the card slot 26 to abut the abutting portion 34, that is, the chip is completed. Card 50 installation. When the chip card 50 needs to be removed, the triggering portion 36 slides in the direction of pulling out the card slot 26, thereby driving the resisting portion 34 to slide out of the card slot 26, and the resisting portion 34 and the chip card 50 are removed. The resisting portion 34 drives the wafer card 50 to slide out of the card slot 26.

The wafer card fixing device drives the wafer card 50 to slide out of the card slot 26 by sliding of the trigger portion 36, so that the wafer card can be easily slipped out of the card slot 26.

It can be understood that the sliding body 30 can be disposed not on the casing 10 and slidably disposed on the lower wall 22 of the combined body 20.
