Mobile communication terminal with signal connector

Abstract

The invention discloses a mobile communication terminal with a signal connection device, which is characterized in that: a device capable of connecting signals between a printed circuit board mounted with multiple chips and a functional part such as a screen display device module is provided. In the flip-type mobile communication terminal of the signal connecting device, the above-mentioned signal connecting device includes: a hinge part connecting the body part of the above-mentioned flip-type mobile communication terminal with the flip part; A plurality of fixed terminals for transmitting the above-mentioned signals; a plurality of spring terminals that maintain elastic contact with each of the above-mentioned fixed terminals and perform relative movement with the above-mentioned fixed terminals. The use of the mobile communication terminal with the signal connection device of the present invention can make the internal space of the mobile communication terminal freely available, and can also greatly reduce the risk of physical damage caused by the opening and closing of the hinge part.

Description

technical field [0001] The present invention relates to a kind of mobile communication terminal (Mobile communication terminal), especially relates to a kind of by providing and can replace the printed circuit substrate that mounts a plurality of chips and the signal between the functional part such as screen display device and connect the flexographic printing The signal connection device of the standardized form of the circuit board (Flexible Printed Circuit Board; FPCB) enables the free use of the internal space of the mobile communication terminal, and can also greatly reduce the risk of physical damage due to the opening and closing of the hinge. communication terminal. Background technique [0002] Generally speaking, a mobile communication terminal is a wireless communication device that is carried by a user and can realize a voice call with a specific object. It is composed of such a system: in order to call a specific mobile communication terminal, including receivi...

Problems solved by technology

[0014] However, if Figure 4 As shown, the problem is that the signal transmission amount of the screen display device, one of the above-mentioned functional parts, mainly uses parallel (Parallel) transmission between 8 and 16 bits. , 700 in the above-mentioned screen display device and chip 410 (refer to figure 2 ) to send and receive the above transmission volume, it is necessary to use a multi-layer structure (Multi-Layer)

[0015] In addition, for the chip 410 mentioned above (refer to figure 2 ) and the functional parts such as the above-mentioned screen display device 310 are connected to the signal, and the connector 610 with dozens of pins (Pin) connected to the above-mentioned FPCB600, 700 (refer to figure 2 ) and connector 710 (refer to image 3 ), must also be arranged on the above-mentioned fuselage part 200 at the same time (referring to figure 1 ) and the above flip part 300 (refer to figure 1 ), thus causing the problem of PCB400 space inefficiency

[0016] In addition, from a structural point of view, it is difficult for the above-mentioned FPCB600, 700 to properly shield (Shield), and the chip 410 mounted on the above-mentioned PCB400 (refer to figure 2 ) and the connection distance between the above-mentioned functional parts are too long, so the signals sent and received by the above-mentioned FPCB600, 700 will emit noise (Noise) to the communication signal receiving end of the mobile communication terminal during transmission. ) interference, resulting in mobile communication terminal 100 (refer to figure 1 ) The problem of low performance of the communication signal receiving end
