Description

CONNECTOR FOR COMMUNICATING WHICH CONNECTS BETWEEN BATTERY PACK WITH A BUILT-IN CIRCUIT AND MAIN BODY OF MOBILE COMMUNICATION TERMINAL}

The present invention relates to a communication connector, and more particularly to a communication connector for connecting a battery pack embedded circuit and the mobile communication terminal body.

The idea of incorporating additional option circuits into the battery pack has been proposed to extend the functionality of mobile communication terminals. Japanese Patent Laid-Open No. 9-270836, published October 14, 1997, discloses an additional device implemented with a radio circuit embedded in a battery pack detachably coupled to a mobile communication terminal. In addition, Korean Patent Application Publication No. 2001-19664 filed by Kim Tae-jin and published March 15, 2001, includes an MP3 codec and a flash memory module in a battery pack of a mobile communication terminal, and controls audio using a user interface of the mobile communication terminal. The playback apparatus is described.

A representative example in which such a smart card is applied to a mobile communication terminal is a subscriber identification module for providing a roaming service, which is installed in the mobile communication terminal. Such smart cards for mobile communication terminal subscriber identity modules include, for example, a subscriber identity module (SIM) card, a universal subscriber identity module (USIM), a user identity module (UIM) card, a removable user identity module (RUIM) card, and the like. In GSM, a European mobile communication system, the above-described SIM card has been applied as a subscriber identification module, which can be referred to as an interface between a cellular phone and a network, in order to cope with a change of a terminal or a change in a carrier. The SIM card contains information about the user, including a phone number. When the power is turned on, the SIM card transmits and receives information from the SIM card to the network. The USIM card is a UMTS (Universal Mobile Telecommunications System) capable of transmitting third generation, broadband packet-based text, digitized voice or video, and multimedia data at high speeds of 2 Mbps or higher, regardless of where mobile phones or computer users are in the world. As a smart card to be applied to, it is embedded in the IMT-2000 service terminal and can contain user data along with secret authentication data. The UIM is a smart card improved to apply the SIM of the European GSM to the second generation CDMA, RUIM is a removable smart card for applying to the third generation CDMA.

Another example where smart cards are applied to mobile terminals is the use of various types of payment means such as electronic money (eg, transportation cards) or credit cards. For example, in the mobile communication terminal equipped with a smart card, six connection terminals are electrically connected to the mobile communication terminal, and two terminals are connected to the RF antenna embedded in the mobile communication terminal, thereby providing an RF antenna and an external interface. The payment information between the readers can be used to pay post-payment of transportation charges through the communication function of the mobile communication terminal.

The smart card 20 to which the thin plate 30 is mounted is fixed. In FIG. 13, a departure prevention jaw 38 is further provided on the rear surface 32 of the mobile communication terminal to help fix the metal thin plate 70.

In addition, in a known smart card mounting structure in which electrical connection is made between a terminal provided by the mobile communication terminal main body side and a terminal on the bottom of the smart card for communication connection with the microprocessor of the main body, the smart mounting structure is not modified. By forcibly inserting a clip member (according to the present invention) into a card, an electrical connection between a terminal of a battery pack built-in circuit and a terminal provided separately from a printed circuit board of a mobile communication terminal by an up / down connection part provided in the clip member This becomes possible. In this case, the main body housing of the mobile communication terminal can increase the space for seating the smart card by only the thickness of the clip member, and in some cases, the main body housing of the mobile communication terminal is elastic in itself. It can be used as it is without modifying the space structure for seating the card. In addition, a housing hole for exposing the known first connector to the outside may be designed as wide as a space for electrical connection between the lower connection portion of the clip member and the terminal of the main printed circuit board.

In addition, the printed circuit board may further include only a terminal for communication with the battery pack embedded circuit. As a solution for minimizing the space utilization of the printed circuit board and for the robustness of the connection, it may be possible to use the male / male board-to-board connectors commonly used in the design of the mobile communication terminal circuit.

In addition, in a known smart card mounting structure in which electrical connection is made between a terminal provided by the mobile communication terminal main body side and a terminal of the bottom of the smart card for communication connection with the microprocessor of the main body, a battery pack embedded circuit provided at the bottom of the battery pack Electrical connection occurs on the upper surface of the existing smart card fixing part covering at least a part of the upper surface of the smart card on which each terminal from is mounted, and the terminal of the battery pack internal circuit is connected by the upper / lower connection (according to the present invention). And electrically connected between terminals provided separately from the printed circuit board of the mobile communication terminal. In this case, the anti-lower connection portion can be used to bend the elastic piece or the pattern is very simple and can be implemented, the printed circuit board need only further include a terminal for communication with the battery pack embedded circuit.

In addition, since the mobile communication terminal performs communication with the battery pack embedded circuit together with the conventional smart card, the data transmitted can be buffered in the middle, so that a smooth communication between the microprocessor of the main body and the two components is possible. do.
