Description

External device connection device with handset {connection cord for contact of a (telephone) receiver}

The present invention relates to a handset-attached external device connection device, and more particularly to a handset-attached external device connection device to be able to combine the handset and the external device of the telephone.

In general, the handset is installed in the telephone to hear the voice of the other side, has a low sensitivity speaker type, is coupled to the telephone body and the connection cord.

By the way, such a connection code has a function of connecting the telephone base and the handset, but in order to actually provide it because it can not provide a function such as transmitting a voice to another external device or recording the call if necessary There is a problem to be equipped with a separate external equipment. In addition, even if you have an external equipment is difficult to install, difficult to implement the general public is quite inconvenient, and the cost for such equipment also acts as a significant burden.

The present invention has been devised to solve the above problems, and it is possible to record the contents of a telephone call on the fly, and to listen to several people at the same time by using an external speaker. It is an object to provide an apparatus.

1 is an explanatory diagram showing a state of use of the handset external device connection device according to the present invention,

Figure 2 is a plan sectional view showing in detail a handset external device connection device according to the present invention.

The object is, according to the present invention, is installed in the cord connecting the telephone base and the connection terminal of the handset is a branch unit having a separate external terminal and coupled to the external terminal of the branch unit to electrically contact the voice signal A modular plug having a plurality of signal terminals, an audio jack electrically connected to any one of a recorder and a speaker for transmitting the voice signal to an external device, and located between the audio jack and the modular plug The plurality of signal terminals are achieved by a receiver-type external device connection device including a cord line for transmitting to the audio jack.

In this case, it is preferable that the audio jack is connected to each signal line to direct current in only one direction in order to prevent an electrical short circuit.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the receiver-type external device connection device according to the present invention. 1 is an explanatory view showing a state of use of the receiver-type external device connection device according to the present invention, Figure 2 is a cross-sectional view showing in detail the receiver-type external device connection device according to the present invention in detail.

As shown in FIG. 1, the external device connection device includes a telephone main body 1 for performing telephone communication with a repeater, and a transmitter and receiver 3 connected to the telephone main body 1 for transmitting and receiving voice. It is installed on the phone. That is, a branch unit 5 connected to each terminal between the transceiver, the handset 3, and the telephone base unit 1, and an external connection cord 7 connected to an external terminal of the branch unit 5 to be connected to an external device. Has)

As shown in FIG. 2, the external connection cord 7 is coupled to an external terminal of the branch unit 5 and has a modular plug 13 having a plurality of signal terminals 11 electrically contacting voice signals. And an audio jack 15 electrically connected to any one of a recorder (not shown) and a speaker (not shown) so as to transmit the voice signal to an external device, and the audio jack 15 and the module. Located between the plug 13 and has a code line 17 for transmitting the audio signal of the plurality of signal terminals 11 to the audio jack 15. At this time, an end portion of the cord line 17 is electrically connected to the signal terminal 11 of the modular plug 13.

Here, the audio jack 15 has a diode 19 connected to each signal line to direct current in only one direction to prevent electrical short-circuit phenomenon, and at its end is a metal terminal connected to the audio and speaker ( 20) is separated into a cathode and an anode and integrated.

The external device connection device as described above is provided between any one of the terminal of the telephone base and the terminal of the receiver and the connection cord. That is, the branch unit 5 is mutually coupled therebetween, and after the external connection cord 7 is attached to the external terminal of the branch unit 5, the audio jack 15 of the external connection cord 7 is recorded with a recorder or a speaker. Connect to complete the join.

When the combination is completed as described above, each time the user makes a normal call through the handset, the user can record the contents of the call through a recorder or a speaker, or listen in real time.

The present invention can record the contents of a telephone call immediately without any device, so it is possible to preserve the criminal acts using telephone communication, and it has an indirect effect that can easily eradicate it. Because it encourages people to hear, it has the effect of delivering urgent or good news to many people.

In addition, since the installation is easy and the cost is low, there is no economic burden, and the installation can be performed quickly, maximizing user convenience.
