Description

card reader connector

The utility model relates to a card-reading connector, in particular to a card-reading connector applied to a portable electronic device, which can make a memory card arranged in the electronic device be hidden or exposed.

Recently, portable electronic devices such as cellular or other types of telephones, wireless communication devices, palmtop computers, etc. have become smaller and smaller in size, and their functions have been enhanced, and they are generally further expanded by configuring removable memory cards containing integrated circuits. Functions, such as the subscriber identification card (SIM) device that has formed an industry standard, can make the phone serve the SIM card owner. By changing different SIM cards, one phone can be used by multiple SIM card owners. Another example is a multimedia card (MMC), which can store phonebooks, voice email messages, and other enhanced memory functions.

The above-mentioned memory card is generally mechanically fixed and electrically connected to the electronic device to be configured through a card reader connector. There are two types of card reader connectors for assembling memory cards in the prior art. One is an integrated card reader connector installed in the periphery of the electronic device, so that the memory card can be directly inserted or extracted from the outside, but this card reader connector The memory card can only be matched with electronic devices of specific specifications and its circuit board, so that the memory card can only be assembled in one of the two installation methods of being basically hidden in the body or partially exposed, and cannot provide consumers with a choice. The other is a card-reading connector for installing a memory card completely concealed, such as U.S. Patent Nos. 5,603,629, 5,813,878 and 5,933,328 issued on February 18, 1997, September 29, 1998, and August 3, 1999, respectively. As disclosed in No. 1, the card-reading connectors include a housing part for accommodating electrical terminals and a bearing frame pivotally connected with the housing part to carry the memory card. When the memory card is inserted into the bearing rack, the bearing rack can be The memory card makes contact with the electrical terminals and presses into the electronic device. And as disclosed in U.S. Patent No. 5,831,256 and No. 5,822,183 announced on November 3, 1998 and October 13, 1998 respectively, the memory card is contained in the groove in the electronic device, and it is pressed by a pressure plate on it, but If you want to take out the memory card in the above structures, you must first partially open the housing of the electronic device to lift up the carrier or remove the pressure plate, which is very inconvenient to operate.

The purpose of this utility model is to provide a card reader connector that can be installed in an electronic device in a concealed or exposed manner to meet the needs of consumers for free choice and is easy to operate.

In order to achieve the above object, the utility model provides a two-piece card reader connector, which is composed of a main body and an auxiliary body detachably connected with the main body, and is electrically fixed on the circuit board of the electronic device. The main body is A connector that can operate independently, including an insulator and a metal terminal disposed therein. The memory card can be inserted from a corresponding opening of the electronic device, carried by the insulator, and electrically contacted with the metal terminal. After the auxiliary body is connected to the body, it becomes The extension of the insulator of the body can guide the memory card to be electrically connected with the card reader connector more easily and carry the memory card in a larger area.

The above-mentioned two-piece card reader connector, when only the body is electrically fixed on the circuit board of the electronic device, due to its relatively small size and the convenience of installing the memory card, the body is installed at a distance relatively far from the opening of the electronic device. Nearby, when the memory card is inserted through the opening, part of it will be exposed outside, and when the main body and the auxiliary body are connected and fixed on the circuit board, they are relatively installed far away from the opening of the electronic device, guided by the auxiliary board The memory card is inserted, and the memory card can be fully inserted to realize hidden installation. In addition, for electronic devices of different specifications, if the circuit board utilization space is small, you can choose the body installation of the two-piece card reader connector, and if the circuit board utilization space is large, you can only choose the two-piece The main body of the card reader connector is installed to realize the exposed type, and two pieces can also be installed together to realize the hidden type, so the card reader connector of the utility model can be applied to electronic devices of different specifications, and the insertion and removal of the memory card are all Complete directly, easy to operate.
