Description

CONNECTOR AND A COMMON STRUCTURE FOR MEMORY CARDS THEREOF}

The present invention relates to a connector and a shared structure for a memory card, and more particularly to a connector having a shared structure for a memory card selected to achieve electrical connection to two or more different types of memory cards through one main body.

Many personal handheld devices, such as digital cameras, notebooks, computers, mobile phones, etc., use memory cards to store data. These personal handheld devices have a receptacle for accommodating memory cards. In the prior art, the receptacle has a plurality of holes on only one side for engaging the pin. Therefore, the accommodating part may accommodate only a memory card having a connection blade at one side. However, accepting only one memory card cannot meet the requirements of users these days. Accordingly, improvements to it are disclosed in Taiwan Patent Application No. 090207781, which is a connector that can be combined with a Subscriber Identity Module (SIM) card. It may be installed on a cell phone. It includes a case and a layer structure. The layer structure includes an upper surface having a slot for sharing connection, a blade for sharing connection, a plurality of upper connection blades and a plurality of upper troughs, and a plurality of lower connection blades and a plurality of lower troughs. do. The connection slot has a trough hole, allowing the shared connection blade to make an electrical connection with two SIM cards in the connection slot. The upper connection blades are located in the upper trough for electrical connection with one SIM card. Lower connection blades are located in the lower trough to make electrical connection with other SIM cards.

The cited reference attempts to connect the same memory cards to the same connector. However, nowadays people are highly dependent on personal portable devices. It is not unusual for many people to have more than one personal handheld device, such as a cell phone, a PDA, or the like. Those memory cards are often different. For example, SIM cards for mobile phones are very different from SD cards used in PDAs in the form of metal contacts. In order to accommodate two different types of memory cards, the personal portable device must have a special receptacle different from the receptacle for the SIM card. This causes space allocation problems in personal portable devices and must increase the number of contacts in the circuit. It is contrary to the trend of increasing value and increasing demand for slimness and lightness. In addition to space allocation issues, packing more elements into less space creates another concern (such as heat dissipation in the chip).

The main object of the present invention is a connector and its memory card having a selected common structure for coupling with a SIM card and another type of memory card (such as an SD card), so that it is not necessary to combine different types of connectors in one host. To provide a common infrastructure.

The connector and its common structure for a memory card according to the present invention include a case and a body coupled thereto. The main body includes an insertion slot having a latch portion at both sides and a terminal anchor portion at the bottom thereof. The terminal anchor portion has a first set of terminals and a second set of terminals that are positioned in an upper and lower manner and are in different forms to make electrical connections with two different types of memory cards.

The above and further objects, features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings.

Referring to Fig. 1, the connector according to the present invention and its shared structure for a memory card include a case 10 and a body 30 joined together as did conventional connectors. Since such a coupling technique is known in the art, the detailed description is omitted.

The main body 30 has a structure generally used to allow various memory cards to make an electrical connection. The body includes an insertion slot 31, a latch portion 32, and a terminal anchor portion 33 for accommodating various memory cards.

The latch unit 32 is a first latch unit respectively positioned at both sides of the insertion slot 31 to hang various types of memory cards (SIM card, SD card, CF card, etc.) in the insertion slot 31. 321 and the second latch portion 322. Since the latch technology is also known in the art, detailed description thereof will be omitted.

The terminal anchor portion 33 is located on the bottom surface of the insertion slot 31 by bonding, latching or fastening and is integral with the body 30. The terminal anchor portion 33 includes a first terminal set 331 and a second terminal set 332. The second terminal set 332 is coupled with a SIM card, and the first terminal set 331 is coupled with another type of memory card (SD card, CF card, etc.). (The above arrangement serves only as an embodiment and is not a limitation of the present invention.) The first and second terminal sets 331 and 332 are top and bottom on the terminal anchor portion. Is located. In addition, the first and second terminal sets 331 and 332 have one end portion extending into the insertion slot 31. The bottom surface of the insertion slot 31 corresponding to the extension end of the second terminal set 332 has a trough 312 to support the extension end. However, the contact end of the second terminal set 332 is exposed outside the trough 312 to contact the metal contact of the SIM card.

Referring to Fig. 2, the present invention will be described in combination with various types of memory cards. The SIM card 50 is inserted into the insertion slot 31 at all times. Firstly, one side of the SIM card reaches the first latch portion 321 to achieve a first stage engagement, and the insertion continues until the bottom end of the insertion slot 31 is reached. The other side is then caught on the second latch portion 322 to form a second stage coupling to completely engage the SIM card in the insertion slot 31. On the other hand, the second terminal set 332 on the bottom layer of the terminal anchor portion 33 having one end extending into the insertion slot 31 is coupled with the metal contact portion 51 of the SIM card 50, An electrical connection is established between the connector and the SIM card 50. This is the first condition of use of the present invention for various types of memory cards.

Referring to Fig. 3, the present invention in combination with other types of memory cards will be described. The SD card 70 is inserted into the insertion slot 31 until one side reaches the first latch portion 321 to engage at the selected position. The insertion continues until the bottom end of the insertion slot 31 is reached, and the other side is caught on the second latch portion 322 to achieve a complete engagement in the insertion slot 31. On the other hand, the first terminal set 331 on the upper layer of the terminal anchor portion 33 having one end extending into the insertion slot 31 is engaged with the metal contact portion 71 of the SD card 70. Therefore, an electrical connection is achieved between the connector and the SD card 70. This is the second condition of use of the present invention for other types of memory cards.

In addition, the terminal anchor portion 33 adopts an assembly type. Referring to FIG. 4, the terminal anchor portion 33 may be changed to be suitable for coupling with other types of memory cards (CF cards, etc.). Therefore, the predetermined terminal anchor portion can be assembled on the bottom surface of the insertion slot 31 according to the production conditions. Therefore, molding cost can be reduced, production verification and production time can be saved, and product competitiveness can be increased.

While the preferred embodiments of the present invention have been described for purposes of illustration, modifications and other embodiments of the disclosed embodiments of the present invention can occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments without departing from the spirit and scope of the invention.
