Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention generally relates to SIM card (subscriber identification module cards) holders and, more particularly, to a SIM card holder for seating a SIM card onto an electronic device such as a mobile phone.
2. Discussion of the Related Art
Nowadays, mobile phones are widely used and bring convenience to our lives, mobile phones have become a part of modern life. Every mobile phone has a SIM card for carrying information which is necessary for people to operate the mobile phone. The SIM card may also contain personal information for the subscriber, for example, a listing of frequently used telephone numbers. Therefore, a SIM card holder is necessary for holding the SIM card in electronic devices such as mobile phones.
Referring to FIG. 1, a typical SIM card holder is disclosed as follows. The SIM card holder includes a mounting base 80 and a locking element 90. A receiving groove 801 is defined in the mounting base 80 for receiving a SIM card. The locking element 90 includes a fixing portion 901, an operating portion 903 and a deformable portion 905. The locking element 90 is mounted on the mounting base 80. The fixing portion 901 protrudes over the receiving groove 801 to hold the SIM card. When the operating portion 903 is pulled manually, the deformable portion 905 deforms and the fixing portion 901 moves away from the receiving groove 801, thereby the SIM card can be removed from the receiving groove 801 of the mounting base 80.
It can be seen that the deformable portion 905 of the locking element 90 is very large, and a height of the deformable portion 905 will increase when pulling the operating portion 903. Thus, the SIM card holder occupies too much space, which results in an overly large size for electronic devices such as mobile phones. In addition, when a person is installing or removing the SIM card, he or she must hold the mobile phone and operate the locking element 90 with one hand and remove the SIM card simultaneously with another hand. That is, it is very inconvenient for the user to operate the SIM card holder.
What is needed, therefore, is a SIM card holder which has small height and is easily operated.

SUMMARY OF THE INVENTION

A SIM card holder includes a base and a catching mechanism. The base defines a receiving groove and a slot. The receiving groove is configured for receiving the SIM card therein. The base comprises a protrusion. The protrusion and the slot are arranged at two opposite sides of the receiving groove. The catching mechanism comprises a main board having a bending piece and a bending hem at two opposite ends thereof. The bending hem is engaged in the slot. The bending piece is engagable with the base so as to lock the SIM card in the receiving groove. The main board comprises an elastic slice resisting the protrusion when the bending piece is engaged with the base.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 2 and FIG. 3, a SIM card holder includes a housing 10 and a catching mechanism 20. A SIM card 30 is fixed on the housing 10 by the catching mechanism 20, and the SIM card 30 is electrically connected to a print circuit board (PCB, not shown) by a connector 40.
The housing 10 is approximately cuboid-shaped with a front surface 100 and a back surface 101. A receiving cavity 102 is defined in a bottom portion of the housing 10 for receiving a battery (not shown), and an opening 104 is defined in a top portion of the housing 10 for receiving the connector 40. The receiving cavity 102 is defined by four sidewalls 103. A nick or a hole 105 is defined in a sidewall 103 near the opening 104. Being adjacent to the nick 105, a protrusion 108 is formed on the front surface 100 of the housing 10, and located between the nick 105 and the opening 104. A slot 110 is defined at the front surface 100 of the housing 10 and is opposite to the protrusion 108 relative to the opening 104. Two strips 112 are formed on the housing 10 at the front surface 100 and are perpendicular to the protrusion 108 and the slot 110. Two ends of each strip 112 bend towards another strip 112, thereby cooperatively defining a receiving groove 114 for receiving the SIM card 30. A batten 116 is formed on the back surface 101 of the housing 10, aligning with the slot 110. Two catch boards 118 and two catch pieces 120 are formed on the back surface 101 of the housing 10 surrounding the opening 104 for housing the connector 40. The connector 40 is disposed at the back surface 101 and exposed out of the front surface 100 via the opening 104.
The catching mechanism 20 is approximately sheet-shaped having a main board 201. Two ends of the main board 201 perpendicularly bend in a same direction to form first bent portions and part of the first bent portions further perpendicularly bend in a same direction to form second bent portions, thereby forming a bending piece 202 and an opposite bending hem 204 at two ends of the main board 201. The bending piece 202 bends inward of the main board 201, and the bending hem 204 bends outward of the main board 201. An elastic slice 206 is forced out of the main board 201 adjacent to the end of the bending piece 202 by a punch. An end of the slice 206 adjacent to the bending piece 202 is a free end and the opposite end connects to the main board 201. A hook 207 is formed at the free end of the slice 206. A width of the main board 201 is corresponding to a minimal distance between the two strips 112 of the housing 10. A width of the slice 206 is corresponding to a length of the protrusion 108. The bending hem 204 of the catching mechanism 20 is inserted into the slot 110 of the housing 10 and the slice 206 resists the protrusion 108.
The SIM card 30 carries information that is necessary for operating the telephone and personal information of the owner. The SIM card 30 is a kind of integrated circuit card. The SIM card 30 is mounted in the receiving groove 114 and electrically connected with the connector 40.
Referring to FIGS. 4 through 6, in assembly, the SIM card 30 is mounted in the receiving groove 114 beforehand. The bending hem 204 of the catching mechanism 20 is inserted into the slot 110 of the housing 10, and the catching mechanism 20 is rotated about an angle of 90° afterward to make the main board 201 approximately parallel to the front surface 100 of the housing 10. The catching mechanism 20 is moved in a direction parallel to the strips 112 to make the catching mechanism 20 move towards the receiving cavity 102. Then the catching mechanism 20 is pressed downwards. The catching mechanism 20 is moved in a direction parallel to the strips 112 to make the catching mechanism 20 move away from the receiving cavity 102, thereby the bending piece 202 engages with the housing 10 at the position adjacent to the nick 105 and the bending hem 204 engages with the housing 10 at the position of the slot 110. The hook 207 of the catching mechanism 20 resists the protrusion 108. A cooperation of the bending piece 202, the bending hem 204 and the hook 207 with the housing 10 holds the catching mechanism 20 in position. The SIM card 30 is thus held on the housing 10. It can be seen that the SIM card holder merely includes two simple elements, i.e. the housing 10 and the catching mechanism 20. Thus, the SIM card holder is quite simple. In addition, the catching mechanism 20 is a thin board. Thus, the SIM card holder does not occupy much space.
Referring to the FIG. 7, when removing the SIM card 30 from housing 10, at first, the hook 207 of the catching mechanism 20 is clawed and raised over the protrusion 108 of the housing 10, then the catching mechanism 20 is moved in parallel relative to the front surface 100 of the housing towards the receiving cavity 102. Thus, the bending piece 202 and the bending hem 204 disengage with the housing 10, shown in FIG. 7. Finally, the catching mechanism 20 is rotated through an angle, thereby the SIM card 30 is made removable from the housing 10. The SIM card 30 can also be removed after removing the catching mechanism 20 as the catching mechanism 20 is also removable from the housing 10. As such, the SIM card holder has greater ease of use.
Referring to FIG. 8, the SIM card holder is applied in an exemplary mobile phone having a front cover 60 and a rear cover 70. The front cover 60 and the rear cover 70 cooperatively define an enclosed space. The housing 10 is mounted in the enclosed space.
In alternative embodiment, the receiving groove 114 can also be a slot defined in the housing 10, correspondingly, the strips 112 can be omitted. The housing 10 can be just a base for mounting the catching mechanism 20 and the SIM card 30 without the receiving cavity 102 for the battery.
It is believed that the embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
