Description

Connection device of PCB and other accessories for communication terminal

The present invention relates to a communication terminal, and more particularly to a connection device of the communication terminal PCB and other accessories.

In general, the communication terminal refers to a mobile phone or a PCS that is widely used in recent years, and the functionalities and structural improvements of the device are continuously made due to the problems caused by the increased use thereof.

1 is an exploded perspective view of a portion of the upper side of a conventional communication terminal, the configuration based on this drawing is a front case (1) integrally formed with a fastening boss (2) for fastening the screw (3) on both sides of the inner surface And, the PCB (4) is fixed to the inside of the front case by a screw (3), the receiving speaker (5) is fixed to the front case (1) to hear the other party's voice, and the front case ( It is installed on one side of the inner side of 1) and consists of a buzzer (6) for audibly informing it when received.

Meanwhile, the receiving speaker 5 and the buzzer 6 are connected to the PCB 4 by a connector 7 and a wire 8, and the connector 7 is connected to the PCB 4. Is installed on both sides of the back side, and the receiving speaker (5) and the buzzer (6) are located in front of the PCB (4). After connecting the other side to the connector (7) in the state connected to the) is fastened the PCB (4) to the front case (1) by a screw (3).

Therefore, as described above, the structure of connecting the connector 7 and the receiving speaker 5 or the connector 7 and the buzzer 6 to the wire 8 is cumbersome in connection with the assembling structure of the communication terminal. However, due to the connector 7 and the wire 8, the internal structure is complicated, there is a problem in delaying the assembly time.

As a result, productivity has been reduced and product cost has been a factor.

The present invention has been made to solve the conventional problems as described above, the purpose is to simplify the internal connection structure of the product to improve the assembly.

The present invention for achieving the above object is a front case formed with a fastening boss for fastening the screw on the inner surface, a receiving speaker which is fixed to the front case can hear the voice of the other party, one side of the inner surface of the front case A buzzer fixed to the PCB to generate a reception sound, and a PCB fixed to the fastening boss of the front case by a screw; The receiving speaker, the buzzer and the PCB to provide a connection device between the communication terminal PCB and other accessories, characterized in that connected by FPC (Flexible Printed Cable).

Hereinafter, the configuration and operation of the connection device between the communication terminal PCB and other accessories with reference to the accompanying Figures 2 to 3 will be described in detail.

According to Figure 2 communication terminal has a front case (1) formed with a fastening boss (2) so that the screw (3) can be fastened to both inner corners, and a receiving speaker that can be heard in the front case fixed to the front case 5, a buzzer 6 fixed to one inner surface of the front case 1 to generate a reception sound, and a PCB 4 coupled to the fastening boss 2 by a screw 3, and the like. have.

Meanwhile, a first connection part 50 is provided on the surface of the receiving speaker 5 so that a (+) (-) signal can be received, and a (+) (-) signal is also provided on the surface of the buzzer 6. The second connection 60 is provided to be received.

In addition, a flexible printed cable (FPC) 9 is mounted on the upper portion of the receiving speaker 5 and the buzzer 6 so as to be connected to the first and second connecting portions 50 and 60 in the drawing. (9) is used for devices requiring thinning (for example, computers or telephones). The circuit board and other parts are interconnected by wrapping a plurality of core wires arranged side by side in a vinyl sheath to make them wide and thin. It is to.

One end of the FPC 9 is provided with a third connecting portion 90 to connect with the PCB 4, and the PCB 4 is provided with a fourth connecting portion 40 so as to be connected to the third connecting portion 90. It is.

In addition, a hole 91 is formed in the center of the third connecting portion 90 so that the screw 3 can pass therethrough.

Therefore, during assembly, the FPC 9 is placed on the receiving speaker 5 and the buzzer 6 so as to be connected to the first and second connecting portions 50 and 60 of the receiving speaker 5 and the buzzer 6. At the same time, the hole 91 formed at one end of the FPC 9 coincides with the screw groove 20 of the fastening boss 2.

In this state, the PCB 4 is placed on the FPC 9 so that the fourth connection part 40 formed on one bottom surface of the PCB 4 and the third connection part 90 formed on the top surface of the FPC 9 are connected. At the same time, the screw holes 4a formed at both corners of the PCB 4 and the holes 91 of the FPC 9 and the screw grooves 20 of the fastening boss 2 are matched to each other, and then tightened by screws 3. Is complete.

For reference, FIGS. 4A and 4B illustrate the structures of the fourth connection portion 40 of the PCB 4 and the third connection portion 90 of the FPC 9, and the pattern of the third connection portion 90 is It consists of the (+) (-) signal line 92 of the receiving speaker and the (+) (-) signal line 93 of the buzzer, and the pattern of the fourth connection part 40 is also positive (-) of the receiving speaker. The signal line 41 and the (+) (-) signal line 42 of a buzzer are comprised, respectively.

Therefore, when the third connecting portion 90 and the fourth connecting portion 40 are connected, the receiving speaker signal lines 92 and 41 and the buzzer signal lines 93 and 42 of each connecting portion are connected to each other.

The connection device between the communication terminal PCB and the other accessories as described above can be easily assembled because the connection structure is simple, as well as shortening the assembly time, thereby increasing the productivity.
