The present invention relates to an electrical cord lock set, and more particularly to an electrical cord lock set for use in cross-connected cabinets or wiring cabinets.

Most telegraph wiring cabinets do not have locking devices, so wiretaps, splices, or breakouts can easily occur. This situation damages both the subscriber and the Post Telephone and Telegraph (PTT).

Some typical cabinets are unlocked with keys of the same size and shape. Thus, with only one key, the key holder can unlock all cabinets with the same keyhole shape. Although locked, these types of cabinets are still easily left out from eavesdropping, splices or breakouts. Even if the cabinet is locked by an electrical cord lock of the same cord, a similar problem still exists.

There is still a typical cabinet that is locked with keys of different sizes and shapes. Management of keys is difficult and inconvenient because the cabinets are large and different keyholders for a particular cabinet are not always in the same place. Typical electrical code card locks of different cords still have similar problems.

There is also a typical cabinet with an electrical cord lock electrically connected to a fixed power supply and a keyboard for input from the input cord. There is a power supply problem because the power supply for the electric code lock cannot always be advantageously obtained. Repair and maintenance problems exist because the keyboard is on the surface of the cabinet and susceptible to damage by inquisitive people. A security problem exists because the code in the electrical code lock is fixed and cannot be changed.

This application is an attempt to address this situation encountered by the prior art.

The main object of the present invention is to provide a set of electrical cord locks that can be powered by an unfixed power supply.

The present invention will be more fully understood by reference to the following description and accompanying drawings, which form an integral part of the present application.

In FIG. 1, the sensing center according to the present invention comprises an answering machine 5 and a computer 4, the answering machine 5 being electrically coded by the communication circuit 19 shown in FIG. Connected to the set, the electric code lock set according to the present invention is a code confirmation control device (6), code storage device (22), automatic dial and receiving circuit (21), electronic connector (20), electronic sensor (8), An electric lock 37 comprising a power supply 10, a first recharge battery 11, a warning device 9 which is an amplifier, an electric lock circuit 23 which is an electronic switch, and a relay 32 with a coil 33. ), A blocking board 25 and a latch 31 and a receiving device 26 which are generally blocked by the board 25.

The power supply 10 obtains DC power from the telephone exchange station via the communication circuit 19 and supplies power to the code storage device 22, the code confirmation control device 6, and the automatic dial and answering device 21.

The first recharge battery 11 is recharged by the power supply in normal operation, but when the communication circuit 19 is disassembled, the battery 11 takes on the function of the power supply 10.

In FIG. 2, the electric cord lock set includes a controller 13, a code input device 15 as a keyboard, a buzzer 14, a portable lock release device power source 34 as a second recharge battery, and an optical fixture 12 ), A portable lock release device having a power indicator 27, a general operation indicator 28, and a lock-request indicator 29. The portable lock release device 2 is connected to the code confirmation control device 6 by the interconnection of the output device 30 and the reception device 26.

The detection center is connected to the code confirmation control device 6 via an automatic dial and reception circuit 21, an electronic connector 20, and a communication circuit 19, so that the detection center presets the code in the code storage device 22. It is possible to change the preset in the code storage device 22, and to selectively permit the electric code lock set in the enable mode or the disable mode.

After the receiving device 26 and the output device 30 are connected, input codes input through the keyboard 15 and processed by the encoding device in the controller 13 are transmitted to the code confirmation control device via the wiring a. Then, after comparing the preset code in the code storage device 22 with the input code, the code confirmation control device 6 generates a lock release signal that causes the electronic switch 23 to turn on if the two codes are the same. . Since the electronic switch 23 is turned on, the second recharge battery 34 supplies power to the electric lock 37 via the wiring b so that a current flowing through the coil 33 is generated, and thus, a magnetic field (right hand of ampere). Law and Faraday's law of induction) are generated, and the blocking board 25 is converted by the magnetic force by the magnetic field. Since the latch 31 is no longer blocked by the blocking board 25 (shown in FIGS. 3 and 4), the latch 31 is moved to the unlock position for executing the lock release procedure. The code confirmation controller 6 then communicates with the sensing center to notify that the lock 37 has been released. In addition, the electric lock release device holder uses the light fixing portion 12 as the turn-on of the start switch 18 for illumination.

The electronic sensor 8 is installed on the door of the cabinet. The electronic sensor 8 provides a shorted switch function when the door is closed, and the electronic sensor 8 provides an open switch function when the door is opened. If the keyboard 15 does not enter the same input code as the preset code into the code confirmation control device 6, and the electronic sensor 8 detects that the door of the cabinet is opened, the door of the cabinet is undesirably unlocked. It is clearly damaged. At this time, the code confirmation controller 6 initializes the automatic dial and the receiver 21 to communicate with the computer 4 of the detection center so that the computer 4 shows the warning information, and the code confirmation controller 6 makes possible A warning signal is generated by the amplifier 9 to scare the intruder.

When the portable lock release holder closes the door of the cabinet, the electronic sensor (8) provides a short-circuit switch function, and information that the door of the cabinet is closed is sent to the code checking device (6) so that the lock request indicator is set to the electrical code lock set. Turn on to indicate that is locked.

In the meantime, the buzzer 14 starts to ring. After locking the electric lock and converting the latch 31 to the locked position, the portable lock releaser holder must turn on the confirmation switch 16 to ensure that the electric lock is correctly wound. That is, the controller 13 in the portable lock release device 2 transmits a signal to the code confirmation control device 6, and thus generates a control signal for turning off the electronic switch 23 to the coil 33. No current flows and no magnetic force is generated, so the latch 31 returns to the "locking position" and latches the lock. At this moment, the code confirmation controller 6 generates a signal to the controller 13, The request indicator 29 is turned off and the buzzer 14 stops ringing, and then the portable lock release device holder separates the output device 30 from the receiver 26. Code Confirmation Control The device 6 generates a signal for the automatic dial and answering circuit 21 to communicate with the sensing center and the communication circuit 19. For example, the electrical code lock set is locked and when the electrical code lock set is locked. The information is transmitted to the computer 4.

According to the present invention, the electrical cord lock set also includes a second recharge battery 34 and a select switch connected to the sensing center. When the switch is connected to the second recharge battery 34, as mentioned above, the lock release signal is generally operated to release the electric lock 37 without using the portable lock release device 2.

Finally, as mentioned above, the sensing center changes the preset code in the code confirmation control device 6 so that the circuit in the code confirmation control device 6 returns to the initial state after the preset code is changed.
