Description

TECHNICAL FIELD [0001] The present invention relates to a loss signal shielding device for a wireless communication device,

The present invention relates to a wireless communication device, and more particularly, to a loss signal shielding device of a wireless communication device for shielding a frequency signal lost when a PCB connector is connected to a filter module.

2. Description of the Related Art [0002] As is generally known, a wireless communication device such as a base station of a wireless communication system is equipped with various communication devices. The wireless communication device includes a radio frequency filter And a high power amplification module (Power Amplifier Module) connected to the filter module and amplifying a signal transmitted from the base station system and providing the amplified signal to a radio frequency filter.

In particular, the printed circuit board may be provided with a connection connector for transmitting a frequency signal to a radio frequency filter.

1 is a schematic view of a connection connector 10 provided on a general printed circuit board 2.

Referring to FIG. 1, a connection connector 10 may be provided on one surface (hereinafter, referred to as a bottom surface) of a printed circuit board 2 to transmit a frequency signal to a radio frequency filter.

The connection connector 10 may include a coupling jack 20 soldered to the printed circuit board 2 and a cable plug 30 receiving the signal of the coupling jack 20. The connection connector 10 may have a pin coupling structure in which the coupling jack 20 is seated on the cable plug 30 and electrically connected thereto.

Specifically, the joining jack 20 may be provided at one end thereof with a plurality of connecting protrusions 21 so that the connecting protrusions 21 are soldered (S) through the through holes of the printed circuit board 2 have. The other end of the coupling jack 20 may be provided with a connection housing 22 surrounding the pinhole 23 and the pinhole 23. A cable plug 30 to be described later is inserted into the connection housing 22 and a connection pin 32 of the cable plug 30 is inserted into the pin hole 23 to be electrically connected.

The cable plug 30 may be provided with the other end connecting portion 35 connected to the RF filter and the plug housing 31 inserted into the pinhole 23 and on which the connecting pin 32 is mounted. The plug housing (31) can be provided to flow in the cable plug (30). A plurality of slots 33 may be provided in the longitudinal direction of the plug housing 31 so as to be variably fitted inside the connection housing 22 around the periphery of the plug housing 31.

FIG. 2 is a view schematically showing a state where a connection connector 10 coupled to a printed circuit board 2 is coupled to transmit a general radio frequency signal, and a part where a frequency signal is lost.

Referring to FIG. 2, a connection connector 10 connected to the printed circuit board 2 for transmitting a frequency signal will be described. The coupling projections 21 of the coupling jack 20 are coupled to the lower surface of the printed circuit board 2 as the coupling projections 21 penetrate the printed circuit board 2 and are soldered S on the upper surface of the printed circuit board 2 . In this state, as the plug housing 31 of the cable plug 30 is fitted into the connecting housing 22 of the engaging jack 20, the connecting pin 32 can be inserted into the pin hole 23 to be electrically connected .

In such a coupling structure, when a shock or a twist occurs in the printed circuit board 2, the plug housing 31 is provided to be able to flow in the cable plug 30, so that the plug housing 31, The connection pin 32 can be maintained in a state of being connected to the pinhole 23. [ Therefore, the connection connector 10 can maintain electrical coupling even when a certain degree of deformation or impact occurs.

However, when a frequency signal flowing through the printed circuit board 2 flows into the connection connector 10, frequency signals may leak due to generation of gaps due to the coupling.

Specifically, when the coupling protrusions 21 are soldered (S) on the upper surface of the printed circuit board 2, a gap I may be generated between the coupling jack 20 and the lower surface of the printed circuit board 2 . The frequency signal leaks through the gap I between the joining jack 20 and the lower surface of the printed circuit board 2. [

When the plug housing 31 is seated in the connecting housing 22, a gap II is generated between the slot 33 of the plug housing 31 and the engaging surface of the plug housing 31 and the connecting housing 22 . Accordingly, the frequency signal leaks into the gap (II) generated when the plug housing (31) and the connection housing (22) are coupled.

Further, as the plug housing 31 is fluidly coupled with the cable plug 30, a gap can be generated between the end of the plug housing 31 and the cable plug 30. [ Thus, the frequency signal leaks through the gap of the part where the plug housing 31 is fluidly coupled.

The gap between the coupling jack 20 and the printed circuit board 2 as described above and the gap generated by the slot 33 of the plug housing 31 when the plug housing 31 is engaged with the connection housing 22, A frequency signal through the gap of the plug housing 31 that is fluidly coupled to the plug 30 may cause a loss of about 40%.

In addition, in order to prevent the conventional frequency loss, a member for preventing loss may be provided along the periphery of the plurality of connection connectors 10. However, there is a problem that a separate space for providing the above-described member must be provided. The conventional member is provided along the circumference of the cable plug 30 and is provided around the plurality of connection connectors 10 and the member is sealed to the cable plug 30 side, The gap between the member and the printed circuit board 2 can not be sealed with the printed circuit board 2, so that frequency signals leak through the gap and are lost. That is, there is a problem that not only the space is occupied by the member but also the shielding efficiency is poor. In addition, when a leaked frequency signal flows into a neighboring connection cable, interference may occur between frequency signals.

In addition, as described above, since there is a gap between the printed circuit board 2 and the member, the frequency is leaked through the gaps or gaps described above, so that the lost frequency can not be shielded. In addition, there is a problem in that the efficiency of shielding the loss frequency is poor due to the high frequency loss ratio in comparison with the conventional frequency loss ratio.

In addition, the thickness of the RF filter becomes very thick, so that the volume of the RF filter can not only be increased but also the aesthetic appearance may be deteriorated.

Various embodiments of the present invention provide for a gap generated in a connector that is coupled to a printed circuit board to deliver a frequency signal to a radio frequency filter, for example, a gap between a coupling jack and a printed circuit board, a plug housing, It is an object of the present invention to provide a loss signal shielding device for a wireless communication device that can shield a gap generated by a slot of a plug housing and a gap of a plug housing that is coupled to a cable plug to flow freely, .

Also, it is desirable to provide a loss signal shielding device for a wireless communication device that can shield the loss of a frequency signal through a simple structure and process through a gap of a connection connector connecting the printed circuit board and the frequency filter as described above.

The frequency signal leaking through the gap between the connection body 121 and the support part 122 in the connection jack members 121, 122, 123 and 124 is also transmitted to the outside of the shielding member 1340 by the shielding member 1340 Can be prevented from being released.

In addition, the frequency signals lost inside the shielding member 1340 flow through the gaps or gaps again, thereby minimizing the frequency loss and realizing a high output signal.
