The present invention is designed to form a line on a printed circuit board of a conventional endless call prevention device in a printed circuit pattern, and to connect the circuit board of the conventional endless call prevention device directly to an insert terminal for connection on a conventional telephone plug. The present invention relates to a telephone pull-rug integrated unauthorized call prevention device integrating a call prevention device and a telephone plug.

Existing call prevention devices have a structure that connects them in series between the main body of the phone and the phone connection pull lug. Insert the phone plug into the telephone outlet, connect the phone plug phone line to the call prevention device, and prevent the unauthorized call. Since a separate telephone line from the device to the main body of the phone must be connected again, it is inconvenient to install and remove, and there is an inconvenience in that an installation space for an unauthorized call prevention device and an installation space for a telephone full lug are separately required.

The present invention is to form a telephone line in the printed circuit board of the conventional call prevention device itself by the printed circuit pattern and the printed circuit pattern is directly connected to the telephone plug connection terminal, so that the unauthorized call prevention device and the telephone plug become a thermo-type, Part of the telephone line, which was required when installing the conventional call prevention device, was eliminated, and it was devised to provide an integrated call prevention device with a telephone plug that can be directly inserted into a telephone connection outlet to minimize installation space.

Ordinary unauthorized passage prevention device is inserted and mounted in series between the telephone line and the telephone line formed between the telephone main body and the telephone plug in order to facilitate the opening and closing of the line, and if the unauthorized call is detected by a separate means (5 The phone is disconnected by temporarily opening the line by activating the wire, and the ordinary telephone connection plug is molded into the telephone line connection insert 2 in the case 2 and attached to the cord stop 10 of the telephone line. In view of the fact that the lugs 9 are fastened directly to the telephone line connection insert 2 with the screw 11, in the present invention, the telephone line connection insert 2 is molded into the case 1, and the telephone line One end of the connection connection insert 2 is inserted into a telephone outlet to form a line like a normal telephone plug, and the opposite end thereof is one side of an opening / closing terminal of the relay 5 of the unauthorized call prevention circuit board 4. Is connected to the printed circuit pattern 3 for telephone line connection, which is formed by extending the wiring line, and the line extends from the other side of the relay 5 opening and closing terminal on the unauthorized call prevention circuit board 4 so that the telephone line in the cord stop wave 10 is extended. By connecting and configuring to configure a certain line up to, when an unauthorized call is detected by a separate means by operating the relay (5) by a separate means to open the line temporarily to block the call by unifying the telephone plug and unauthorized call prevention device have.

When the present invention is described in detail based on the accompanying drawings as follows.

As shown in FIG. 1, a printed circuit pattern for telephone line connection (3) can be connected to a telephone line connection insert (2) by extending a line from one side of an open / close terminal of the relay (5) to a conventional unauthorized call prevention circuit board (4). ), The line extends from the other side of the relay 5 open / close terminal on the unauthorized call prevention circuit board 4, and the printed circuit pattern 7 for the cord connection is formed so that the lugs 9 can be connected. When the relay 5 is opened and closed, a predetermined line is formed from the printed circuit pattern 3 for telephone line connection to the printed circuit pattern 7 for cord connection via the relay 5 on the prevention circuit board 4. Can be opened and closed.

In addition, the case (1) to mold the telephone line connection insert (2), the cord fastening insert (6) and the cord stop mounting portion (9). That is, one end of the telephone line connection insert 2 is formed to be inserted into a telephone outlet like a normal telephone plug to form a line, but the other end of the telephone line connection insert 2 is connected to the case 1 with an unauthorized call prevention circuit. When the board 4 is mounted, the telephone line connection insert 2 than the self-part of the case 1 so that the printed circuit pattern 3 for telephone line connection and the telephone connection insert 2 can be brought into close contact with the screw 11. Is formed by molding so as to protrude slightly higher, and similarly, the cord connection circuit pattern 7 and the cord on the lug 9 and the unauthorized call prevention circuit board 4 are fastened by the screw 11 at the time of the cord connection. The mold insert 6 is formed to protrude slightly higher than the self-part of the case 1 so that the fastening insert 6 can be brought into close contact with the fastening insert 6, and a conventional support for supporting the cord stop 10 as necessary. With cord stopper mounting part 9 .

The above endless call prevention circuit board 4 is mounted on the case 1, and the telephone line connection insert 2 and the telephone connection printed circuit pattern 3 are fastened using the screw 11, and the cord fastening insert (6) and the cord connection printed circuit pattern (7) and lug (9) are fastened to form a line through the relay (5) from the telephone line connection insert (2) to the telephone line in the cord stop (10). Therefore, when an unauthorized call is detected by a separate means and the relay 5 is operated by a separate means, the relay 5 temporarily opens a line to block the call.

In other words, it is possible to integrate an ordinary unauthorized call prevention device and a telephone plug.

In the present invention, since the conventional telephone call prevention device and the telephone plug are integrated, the mounting is completed simply by attaching to the telephone set and connecting with the telephone main body. It is designed to be connected in series between the plugs, so that the telephone plug must be inserted into the telephone outlet, the telephone plug telephone line must be connected to an unauthorized call prevention device, and a separate telephone line must be reconnected from the unauthorized call prevention device to the main body of the telephone. Installation and removal is inconvenient, and the effect of eliminating the inconvenience that the unauthorized call prevention device installation space and the telephone plug installation space is required separately.

Claims (1)

The telephone line connection insert 2 is molded into the case 1 so that one end of the telephone line connection insert 2 is inserted into a telephone outlet to form a line like a normal telephone plug, but one end of the telephone line is unauthorized. Opening and closing of the relay (5) on the endless call prevention circuit board (4) by connecting with the printed circuit pattern (3) for telephone line connection formed by extending the line from one side of the open / close terminal of the relay (5) of the prevention circuit board (4) The line extends from the other side of the terminal to be linked to configure a certain line to the telephone line in the cord stopper 10. When unauthorized call is detected by a separate means, the relay 5 is operated by a separate means to open the line temporarily. Phone plug integrated unauthorized call prevention device, characterized in that to block.
