Description
CARD CONNECTOR
1. Field of the Invention
The present invention relates to a card connector, and particularly relates to a SIM (subscriber identity module) card connector. 2. Description of the Related Art
Mobile communication devices such as mobile phones and portable computers generally use a SIM (subscriber identity module or subscriber identification module) card to store network-specific information used to authenticate and identify subscribers on the network. Most important of the network-specific information are ICCID (integrated circuit card identifier),
IMSI (international mobile subscriber identity), authentication key (Ki), local area identity (LAI), and operator-specific emergency number.
SIM cards are connected to mobile communication devices through
SIM card connectors. FIG. 1 shows one type of conventional SIM card connector used in the industry. The SIM card connector 1, disclosed in U.S.
Patent Publication No. 2010/0055985A1, includes an insulating housing 11, a terminal module 12 having a plurality of contacts 121, a metal shield 15, a switch element 13, and a card receiving mechanism 14. The metal shield 15 can be assembled on and partly cover the insulating housing 11. The metal shield 15 and the insulating housing 11 define a card receiving space. The card receiving mechanism 14 can carry a SIM card and is insertable into the card receiving space. The switch element 13 comprises a movable piece 131 and a stationary piece 132, wherein the stationary piece 132 contacts the movable piece 131 when the card receiving mechanism 14 is not inserted. The movable piece 131 has an arch portion, which protrudes into the card receiving space to contact an inserted card receiving mechanism 14.
When a card receiving mechanism 14 is inserted, the movable piece 132 is pushed away from the stationary piece 131, triggering a card insertion
S1-
signal.
The SIM card connector 1 has a disadvantage. Because the movable piece 132 is moved by the card receiving mechanism 14, a card insertion signal is triggered even if no SIM card is placed in the card receiving mechanism 14, causing unnecessary read/write operations.
In view of the disadvantages of conventional connectors, a new card connector is proposed.
In one embodiment of the present invention, a card connector comprises a tray, a main body, a plurality of terminals, and a detective switch. The tray includes a side wall for defining a card-holding space and a breach region formed on the side wall. The main body includes a front opening for inserting the tray and a side portion defining a side of the front opening. The plurality of terminals are attached to the main body. The detective switch includes a spring member. The spring member is attached to the side portion of the main body and includes a press portion configured to extend into the card-holding space of the tray through the breach region of the tray when the tray is inserted in the main body. The breach region is configured to prevent interference between the press portion and the tray during the insertion of the tray.

The card connector 3 can be mountable on a printed circuit board 6.
In one embodiment, the card locking element 34 is rigid, not elastic, so that an inserted tray 5 can be firmly held.
Referring to FIGS. 3 to 6, the levering member 352, pivoted on a pivot 322, comprises a first arm part 3521 and a second arm part 3522. The first arm part 3521 extends transversely at the rear of the main body 32 and includes a first end portion 35211 having a push tab 35212 that extends upward and can be swung into the receiving space 321 to eject an inserted tray 5. The second arm part 3522 can extend beside the receiving space 321, including a second end section 35221 having a tab portion 35222.
As shown in FIGS. 5, 6, 8 and 12, the main body 32 includes a recessed area 323 transversely extending along the main body 32. A bottom portion of the recessed area 323 extends under the receiving space 321. The bottom of the locking portion 341 is received in the recessed area 323. As such, the movement of the locking portion 341 between a locking position as shown in FIG. 5 and an unlocking position as shown in FIG. 8 or FIG. 12 is confined by the recessed area 323. In another embodiment, the main body 32 does not have a recessed area 323 for receiving the bottom of the locking portion 341.
In particular, the locking portion 341 includes a front corner and a rear corner both formed on the peripheral surface of the locking portion 341.
The front corner is a cut corner or a round corner so that when the tray 5 engages the front corner of the locking portion 341, the tray 5 can easily move along the front corner. The rear corner is a cut corner or a round corner so that when the tray 5 is moved outward, the tray 5 can easily move along the rear corner.
The card locking element 34 further comprises an operating portion 342 extending toward the second arm part 3522 and engaging with the second arm part 3522 for linked movement therewith. Specifically, the operating portion 342 includes a side 3421 opposite the receiving space 321, and the tab portion 35222 of the second arm part 3522 extends adjacent to the side 3421 of the operating portion 342 such that when the locking portion 341 is moved toward the unlocking position, the operating portion 342 can push the tab portion 35222 of the second arm part 3522 to rotate the levering member 352. In particular, the operating portion 342 has a rectangular cross section, and the tab portion 35222 of the second end section 35221 is bent downward to form an L shape such that the second end section 35221 extends around the outside upper corner of the operating portion 342.
In addition, a groove 3422 is formed on the bottom of the operating portion 342, and an elongated projection 327 is correspondingly formed on the main body 32, mated with the groove 3422 and extending along the recessed area 323. The elongated projection 327 passes through the groove 3422 when the card locking element 34 is assembled to the main body 32.
The interaction between the groove 3422 and the elongated projection 327 can further constrain or guide the movement of the card locking element 34.
Furthermore, the card locking element 34 comprises a plate portion 344 movable within a space defined by a bottom surface of the main body 32 and the actuator 351. The plate portion 344 facilitates the proper movement of the card locking element 34.
Referring to FIGS. 6 to 10, the actuator 351 is movable between an outward position as shown in FIGS. 9 and 10 and an inward position as shown in FIGS. 7 and 8 along a direction parallel to the insertion direction of the tray 5. The actuator 351 can move the card locking element 34. The card locking element 34 comprises a first interacting portion 343, and the actuator 351 comprises a second interacting portion 3511. The first and second interacting portions 343 and 3551 are engaged for linked movement of the card locking element 34 and the actuator 351, allowing the movement of the card locking element 34 between the locking position and the unlocking position simultaneous with the movement of the actuator 351 between the outward position and the inward position. The interaction of the first and second interacting portions 343 and 3551 can cause the card locking element 34 and the actuator 351 to move in different directions, for example, two perpendicular directions.
As shown in FIG. 6, in one embodiment, the first interacting portion 343 of the card locking element 34 comprises a pin, and the second interacting portion 3511 of the actuator 351 comprises a slot inclined at an angle, such as 45 degrees, relative to the moving direction of the actuator 351. The slot has two elongated slot edges. When the actuator 351 is moved, one elongated slot edge contacts the pin, pushing the pin to move along the same elongated slot edge so as to move the card locking element 34. Alternatively, when the pin is moved, the pin pushes another elongated slot edge, moving along the same elongated slot edge so as to move the actuator 351. In one embodiment, the pin can have an elliptic cross section.
The actuator 351 can have a plate-like shape, confined in a concave space 325, and moving over a platform 324. The actuator 351 can further have a bent end 3512 restrained in a recessed area 326 included in the main body 32 and disposed adjacent to the front of the main body 32 such that the movement of the actuator 351 can be restricted.
Referring to FIGS. 6 to 10, the card connector 3 further comprises an elastic member 37. The elastic member 37 provides an elastic force counteracting a force moving the actuator 351 inward, and moves the actuator 351 outward when the force is removed. In one embodiment, the elastic member 37 comprises a spring.
In particular, a channel 328 is formed on the platform 324, communicating with the recessed area 326. A supporting member 38 is provided at the end of the channel 328 for engaging with an end of the elastic member 37. The supporting member 38 can have a pin configured to protrude into the elastic member 37. Another end of the elastic member 37 engages the bent end 3512 of the actuator 351.
FIGS. 7 to 10 are used herein to demonstrate the operation of the card locking element 34 and the card ejecting mechanism 35 during the insertion of a tray 5 carrying an electrical card 4. The operation is similar when a single, different size of an electrical card is inserted. As shown in FIGS. 7 and 8, after the inserting tray 5 contacts the locking portion 341 of the card locking element 34, the locking portion 341 is pushed and the card locking element 34 is moved away from the receiving space 321 until the tip of the locking portion 341 is against the right edge of the tray 5. During the movement of the card locking element 34, the first interacting portion 343 of the card locking element 34, which is a pin in the present embodiment, pushes one elongated slot edge, close to the levering member 352, of the second interacting portion 3511, a slot in the present embodiment, and moves along the same slot edge such that the actuator 351 is moved inward and the elastic member 37 is compressed.
Referring to FIGS. 9 and 10, when the rear edge of the tray 5 is close to the rear of the main body 32, the rear edge touches the first arm part 3521 of the levering member 352 and rotates the levering member 352 until the tray 5 is completely inserted. At some moment during the insertion process, the notch 52 of the tray 5 encounters the locking portion 341 of the locking element 34. The locking element 34 is moved toward the notch 52 due to the elastic force produced by the compressed elastic member 37. Without the counterforce from the right edge of the tray 5 to the locking element 34, the elastic force produced by the compressed elastic member 37 moves the actuator 351, and the elongated slot edge close to the levering member 352 of the second interacting portion 3511 pushes the first interacting portion 343 of the card locking element 34, applying a force, a portion of which moves the locking element 34 toward the receiving space 321 until the locking portion 341 of the locking element 34 enters the notch 52. Because the locking portion 341 of the locking element 34 moves into and away from the receiving space 321 linearly, the notch 52 and the locking portion 341 can be fitted closely to each other so that the tray 5 can be securely held after it is inserted.
Referring to FIGS. 9, 11 and 12, the main body 32 has an opening 329 formed on a front side wall of the main body 32 to expose the bent end 3512 of the actuator 351. The tray 5 has a bar member 53 defining a side of the receiving space 321. A hole 51 is formed on the bar member 53, corresponding to the opening 329 of the main body 32. To eject the tray 5, a rod member 41 is inserted into the opening 329 and the hole 51, and pushes the actuator 351. The actuator 351 is moved inward, compressing the elastic member 37. Simultaneously, the elongated slot edge of the second interacting portion 3511 of the actuator 351 pushes the first interacting portion 343 of the card locking element 34 and moves the card locking element 34 away from the receiving space 321; meanwhile, the operating portion 342 of the card locking element 34 pushes the tab portion 35222 of the levering member 352, rotating the levering member 352. The push tab 35212 of the first arm part 3521 of the rotating levering member 352 pushes the rear edge of the tray 5 outward. As the locking portion 341
S11 -
of the card locking element 34 disengages from the notch 52 of the tray 5, the tray 5 is moved outward until the first interacting portion 343 is moved to the end of the second interacting portion 3511, close to an external side wall of the main body 32.
Although the card locking element 34 and the card ejecting mechanism 35 are applied, in the above embodiments, in a card connector 3 receiving a tray, the same card locking element 34 and card ejecting mechanism 35 can also be employed in a card connector directly receiving a card according to another embodiment of the present invention.
An embodied card connector comprises a main body and a detective switch including a spring member for detection of an inserted electrical card, and can receive a tray including a side wall for defining a card-holding space. The spring member includes a press portion, and a breach is formed on the side wall of the tray. The press portion is formed to protrude toward a receiving space of the main body for receiving a tray, and can further protrude into the card-holding space of an inserted tray. The breach region is configured to avoid interference between the spring member and the tray during the insertion of the tray. Moreover, the breach region can reveal a corner portion of the electrical card. The corner portion of the electrical card can contact and push the press portion, deflecting the spring member, activating a card inserted signal.
