The mobile terminal according to the embodiment of the present invention includes: a terminal body A, multiple main power consumption units (not shown in the figure) and multiple terminal connectors 200 . The terminal body A has a battery cavity 100 for installing a battery.

A plurality of main power consumption units 2 are arranged on the terminal body 1 . In the description of the present invention, the so-called main power consumption unit refers to the power consumption unit in the mobile terminal that consumes relatively large power, which can be selected and determined from all power consumption units of the mobile terminal based on the power consumption. The specific quantity can be determined as needed. For example, the mobile terminal may have 20 power consumption units. If the number of main power consumption units is 2, then these two main power consumption units may be the two power consumption units with the top two power consumption among the 20 power consumption units. Electricity unit; if the number of main power consumption units is 5, then these five main power consumption units can be the five power consumption units with the top five power consumption among the 20 power consumption units.

A plurality of terminal connectors 200 are disposed in the terminal body A and exposed in the battery chamber 100 , and the plurality of terminal connectors 200 are respectively connected to a plurality of main power consumption units.

According to the mobile terminal of the embodiment of the present invention, a plurality of terminal connectors 200 are arranged to be connected to a plurality of main power consumption units in a one-to-one correspondence, so that a plurality of power consumption units can be powered by the nearest terminal connector 200 respectively. , so as to avoid complex wiring design on the circuit board of the mobile terminal, reduce ohmic loss, reduce noise interference, and reduce the volume of the mobile terminal and battery at the same time, with simple structure and low cost.

Preferably, the terminal connector 200 and the main power consumption unit, which are correspondingly connected to each other, are adjacent to each other. Thereby minimizing the complexity of wiring, reducing ohmic loss and noise interference.

In an optional embodiment of the present invention, the mobile terminal may be a mobile phone, wherein the main power consumption unit includes a flashlight, a radio frequency power amplifier module, an audio amplifier, a power management module, a voltage conversion device and a backlight. Of course, the present invention is not limited thereto, and the mobile terminal can also be a PDA (Personal Digital Assistant), a tablet computer, and a CMMB.

In some embodiments of the present invention, the three terminal connectors 200 are located on the same side of the battery cavity 100 , as shown in FIG. 3 , on the right side. Correspondingly, multiple main power consumption units may also be located on the same side of the battery cavity 100 . Of course, the present invention is not limited thereto. In other embodiments of the present invention, multiple terminal connectors 200 are divided into two groups, and the two groups of terminal connectors 200 are located on adjacent sides of the battery cavity. Preferably, multiple terminal connectors The connector 200 is asymmetrical with respect to the center of the battery chamber 100 .

As shown in FIG. 1 , two terminal connectors 200 are located on the right side of the battery cavity 100 , and another terminal connector 200 is located on the upper side of the battery cavity 100 .

Optionally, as shown in FIGS. 10 and 11 , each terminal connector 200 includes: a first insulating base 202 ; and a first contact terminal 201 provided on the first insulating base 202 .

Alternatively, the first magnetically permeable material layer 203 is formed by doping the first magnetically permeable material in the first insulating matrix 202 . At this time, the magnetically permeable material can be doped during the forming process of the first insulating matrix 202 . By disposing the magnetically permeable material layer on the first contact terminal 201 in the above manner, the manufacture is simple and the cost is low.

Since the first contact terminal 201 of the terminal connector 200 is provided with a first magnetically permeable material layer 203, when an effective signal within a certain frequency range passes through the contact terminal, the impedance presented is small and does not affect the passage of the effective signal; while for other The frequency noise and interference signal (EMI signal) present a relatively large impedance, which hinders the noise and interference signal, thereby achieving the effect of filtering. The first magnetically permeable material layer 203 may be made of a magnetically permeable material with a high magnetic permeability, for example, a magnetically permeable material with a magnetic permeability greater than 1, specifically, a magnetic ferrite material may be used. In the embodiment of the present invention, there is no particular limitation on the selection of the first magnetically permeable material, as long as the EMI filtering function can be realized. The first magnetically permeable material presents different impedances for signals of different frequencies, thereby blocking noise and interference signals and allowing effective signals to pass through. In other words, the first magnetically permeable material layer 203 presents different impedances for signals of different frequencies.

According to the mobile terminal of the embodiment of the present invention, by setting the first magnetically permeable material layer 203, the electrical connection function of the terminal connector 200 is realized, and it also has an EMI filtering function, which can effectively prevent noise and interference signals (EMI) from passing through the connector Interference between the system and components caused by it. In addition, due to the EMI filtering in the terminal connector 200, the EMI is filtered before entering the circuit board of the mobile terminal, which has a superior filtering effect than filtering on the circuit board, and can better suppress noise and reduce Interference caused by small noisy signals on a circuit board.

Therefore, when static electricity passes through the signal terminal 1, since the opposite second arc portion 420b and the first arc portion 410b easily form a discharge path, the discharge current will pass through the opposite second arc portion 420b and the first arc portion. The discharge path between the parts 410b reaches the ground terminal 2, without causing damage to the electronic components from the signal terminal along the signal line to the electronic components, so as to achieve the purpose of electrostatic protection.

Moreover, the first electrostatic discharge mechanism 4 is not limited to a pointed discharge mechanism, an arc discharge mechanism, or a discharge mechanism composed of a signal metal layer and a ground metal layer extending parallel to each other. According to an embodiment of the present invention, the first electrostatic discharge mechanism 4 may be any discharge mechanism that is conducive to grounding the static electricity flowing through the signal terminal. The specific example above is a preferred example of the first static electricity mechanism 4 and should not be construed as limiting the present invention.
