Description

Red LED recognition circuit for detecting a connection error of cable used in a LAN modular jack and an active patch panel and active patch panel having the same}

The present invention relates to a patch panel for communication equipment. In particular, an active patch panel that allows the operator to visually check the wiring errors of UTP (Unshielded twisted pair cable) cables connecting the RJ-45 connector and the IDC connector. It relates to a red LED lighting circuit and an active patch panel including the same, which can visually inspect a cable connection error when connecting between a LAN and a LAN modular jack.

In general, communication equipment of subscribers is electrically connected to communication network devices such as hubs, switches, routers, patch panels, 110 blocks, terminal blocks, IP cameras, and NVRs through LAN cables to enable communication with each other. In other words, a local area network (LAN) connects a large number of personal computers, workstations, printers and file servers within a modern office.

LAN systems are constructed by physically connecting all these devices with a copper conductor flexible pair LAN cable, and generally an 8-wire cable consisting of four twisted pairs is the most widely used. Some LAN cables contain a thin film of flexible foil that acts as an electrostatic shield.

Each end of the cable is connected in a connector according to the industry standard. Generally, LAN cables are installed through walls, floors, and ceilings of buildings. In addition, LAN cable systems require continuous maintenance, upgrades, and troubleshooting, because LAN cables and connectors are fragile and require movement of offices and equipment, and further new equipment is added.

In order to establish a LAN system in a building, etc., a LAN cable and network equipment required for communication must be provided. Network devices are connected and installed.

When the LAN cable installation and connection work is completed, the technicians first check whether the cable is well installed and connected, and then install the network device. In other words, workers (technologists) connect a LAN cable checker to both ends of the cable to check whether or not the LAN cable is operating normally.

Next, after checking the LAN cable, each network device is connected to the LAN cable as designed in advance, and after setting the parameters of the device, the operation of the network is checked as a whole. Only through these construction steps, the communication network system connected by the entire LAN cable can operate normally.

In this way, since a number of LAN cables are connected to the communication network device, it takes a lot of time to identify the line, line number, disconnection, short circuit, etc. of the aforementioned LAN cable during initial installation or maintenance of the network device and the subscriber's communication equipment. Is being spent.

Particularly, the patch panel for connecting the communication equipment that composes the communication network system performs wiring to the IDC connector after stripping the cable according to each line in order to route the LAN cable drawn from the MDF or IDF to the premises. Carry out.

At this time, the operator manually connects the wirings between the respective equipments to each other. If there is a faulty wiring between the wirings during work, check by connecting the tester terminals to both ends of the terminals connected to the installed communication equipments. Therefore, in the prior art, when a connection failure occurs between wires, the operator must disassemble the installed communication equipment and then perform a re-wiring work for the wire, making the work complicated and difficult to quickly rework.

In addition, there is a disadvantage in that the work environment of the worker is not good because the work of disassembling the cable tie and the cable connected to the line by the initial work at the time of rework must be performed in a narrow space.

Therefore, there is a need for a technology that allows the operator to immediately check the wiring defects of the wirings connected to the communication equipment connection panel.

The RJ-45 connector 1200 is formed on the front of the active patch panel 1000, and a cable (for example, a LAN (Local Area Network) cable, network equipment, local Local outlet terminals, etc.) are connected. Here, the cable consists of a bundle of 8 wires, and each wire is marked with a different color.

The IDC connector 1500 is formed on the rear side of the active patch panel 1000, and provides a cable (eg, UTP cable) for connection with network equipment or other IDF patch panel, and an outlet terminal in a local area. Connect.

In an embodiment, the IDC connector 1500 may perform a wiring operation as shown in FIG. 4 for connection to network communication devices through a UTP cable, an IDF patch panel in another place, or an outlet terminal in a local area. have. At this time, separate numbers are assigned for each signal (R+, R-, T+, T-), and the wires must be connected accordingly. In addition, in the case of twisting with other wires, the wire can be formed with an interval of at least 13mm from the connection part to the twisted part.

The printed circuit board 1300 is formed between the RJ-45 connector 1200 and the IDC connector 1500, fixes the RJ-45 connector 1200 and the IDC connector 1500, and transmits it through a cable. Patterns for performing noise attenuation and signal matching of the signal to be made are also engraved. In the present invention, a plurality of red LED lighting circuits are mounted on the printed circuit board 1300 constituting the active patch panel 1000. The red LED lighting circuit may be formed to correspond to the number of RJ-45 type connectors. Accordingly, 4 blocks of 6 RJ-45 connectors (here, the RJ-45 connector is configured as one configuration and may refer to the port of the RJ-45 connector) are formed on the active patch panel 1000. In this case, a red LED lighting circuit corresponding to 24 connectors may be mounted.

In order to prepare, a support plate for supporting a free space between the printed circuit boards 1300 may be fixedly formed on the upper rear surface.

A through hole is formed in the front cover 2400 to expose a part of the RJ-45 connector 1200 and the printed circuit board 1300. Therefore, the front surface of the RJ-45 connector 1200 is exposed to the outside through the penetration of the front cover 2400, and a part of the printed circuit board 1300 is on the upper surface where the RF-45 connector 1200 is exposed. Make it exposed so that you can rework for incorrect wiring after cable wiring work. Accordingly, the through hole on the upper side of the RJ-45 connector 1200 is covered by the cover 2433.

The active patch panel 1000 of the present invention may further include a heat insulating plate 1600 and a heat radiation plate (not shown). The heat insulating plate 1600 is installed between the IDC connector 1500 and the printed circuit board 1300 to prevent heat generated from the IDC connector 1500 (especially, heat generated from the connection part between the IDC connector 1500 and the cable). It functions to block so that it is not transmitted to the printed circuit board 1300.

The heat insulating plate 1600 is cork, cotton, felt, carbonized cork, foam rubber, asbestos, glass wool, quartz wool, diatomaceous earth, magnesium carbonate powder, magnesia powder, calcium silicate, pearlite, etc. It can be formed as The insulation board 1600 is installed in the entire part except for the connection line (ie, signal line) between the RJ-45 connector 1200 and the printed circuit board 1300, and is a connection part between the RJ-45 connector 1200 and the cable. It can block the heat generated by as much as possible.

In addition, the heat sink is installed in close contact with the IDC connector 1500 to receive heat generated from the IDC connector 1500 to radiate heat to the outside. At this time, the active patch panel 1000 may further include a blowing fan (not shown in the drawing for convenience of explanation) installed on the panel body cover, and the heat transferred to the heat sink is blown to the outside by using a blowing fan. I can do it. The heat sink may be installed in close contact with both sides of the IDC connector 1500.

In this way, the red LED lighting circuit that checks for cable wiring errors connected to the active patch panel of the present invention and the active patch panel including the same connect the RJ-45 type connector and the IDC connector constituting the active patch panel, which is a network communication device. It has the effect of displaying the normal or bad connection status of the UTP cable to the operator by lighting a green LED or a red LED.

Test pads are formed on each wire of the UTP cable, and test pads connected to each of the test pads are formed on the printed circuit board of the active patch panel, so that all wires constituting the UTP cable can be inspected for defective wiring. It works.

4 is a view showing a state in which an IDC connector, an RJ-45 connector, and an 8-pin (PIN) outlet terminal of an active patch panel according to an embodiment of the present invention are connected by a UTP cable.

Referring to FIG. 4 along with FIG. 3, the active patch panel 1000 according to an embodiment of the present invention includes terminals of the IDC connector 1500 disposed on the rear side and the RJ-45 type connector 1200 disposed on the front side. The terminals (more specifically may be referred to as ports) are connected by a UTP cable. In addition, although not shown in the drawing, the terminals of the IDC connector 1500 are connected to the outlet through a LAN cable such as a UTP cable, and various communication facilities may be connected to the outlet. Accordingly, the terminals of the IDC connector 1500 and the terminals of the RJ-45 connector 1200 are selectively connected to each other by the connection connectors OC1 and OC2, as shown in the drawing.

In particular, in the case of defective wiring between the RJ-45 connector 1200 terminals and the IDC connector 1500 terminals, the user's computing device or terminal connected through a communication facility connected to the outlet is appropriate for data (voice or video data). Will not be able to receive.

In addition, as shown in Figure 2, the active patch panel 1000, after the IDC connector 1500 and the RJ-45 type connector 1200 is connected by a UTP cable, since other components are assembled, the IDC connector ( 1500) and the RJ-45 connector 1200, if there is a faulty connection between the terminals, it takes a lot of time and cost to rework.

As shown in Fig. 4, the terminals of the RJ-45 connector 1200 and the terminals of the IDC connector 1500 each have an 8-pin (PIN) structure, and these pins operate as a pair of 2 terminals and 4 pairs of terminals. do. Therefore, similar colors are displayed on the pair of terminals, so that the wires of the UTP cable are normally connected. Accordingly, in the connection connectors OC1 and OC2, colors and numbers corresponding to respective terminals are displayed. The wires that make up the UTP cable are also coated with a specific color on each of the eight wires, allowing the operator to connect the cable without error.

For example, terminal 1 is orange-white (OR-WH), terminal 2 is orange (OR), terminal 3 is green (green)-white (GR-WH), terminal 4 is blue (BL) , Terminal 5 is blue (blue)-white (BL-WH), terminal 6 is green (GR), terminal 7 is brown (brown)-white (BR-WH), terminal 8 is brown (BR) When marked as, the IDC connector and the RJ-45 type connector must be connected by selecting a wire that matches each terminal of the wires constituting the UTP cable.

In particular, as shown in the drawing, pins 3 and 6 of the pins of each terminal are farther apart than other pins, and thus, poor wiring of UTP cables frequently occurs.

The active patch panel 1000 of the present invention turns on the red LED when there is a faulty connection of the UTP cable in the printed circuit board, and turns on the green LED when the normal connection is made. It was made to be able to check whether the wiring was defective.

In particular, the active patch panel 1000 of the present invention turns on a red LED not only when the connection of the UTP cable is normal, but also when a connection failure occurs, so that the operator can check the connection failure.

5 is a diagram illustrating a state in which a connection error is checked after an IDC connector of an active patch panel and an RJ-45 connector are connected by a UTP cable according to the prior art. 6 is a view showing a state in which an IDC connector and an RJ-45 connector of an active patch panel inspect a wiring error using a red LED lighting circuit according to the present invention. 7A and 7B are diagrams showing a state in which a red LED lighting circuit disposed on an active patch panel of the present invention displays a wiring state of a UTP cable connecting an IDC connector and an RJ-45 connector to an operator.

Referring to FIGS. 5 to 7B along with FIG. 3, the active patch panel 1000 of the present invention has an RJ-45 connector 1200 disposed on the front side, and an IDC connector 1500 disposed at the rear side, and these are UTP cables. Are connected to each other by

In the prior art, a lighting circuit 335 composed of a resistor (R), an inductor (L) and a green LED (GD) is turned on on the printed circuit board 1300 of the active patch panel 1000, but the prior art is a UTP cable. The wiring defect was confirmed by connecting the UTP cables of terminals 3 and 6 and the terminal of the lighting circuit 335, where the connection defects frequently occur, but on the printed circuit board 1300 of the active patch panel 1000. There was no patch panel developed so that the lighting circuit 335 composed of a resistor (R), an inductor (L), and a red LED (RD) was turned on.

Therefore, as shown in FIG. 5, terminal 6 of the IDC connector 1500 and terminal 6 of the RJ-45 type connector 1200 are normally connected, and terminal 3 of the IDC connector 1500 and the RJ-45 When the 3rd terminal of the connector 1200 is normally connected, when the test signal is applied through the UTP cable (outlet modular) connected to the IDC connector 1500, the lighting circuit 335 and the 3rd and the IDC connector 1500 Terminal 6 and the UTP cable connecting the IDC connector 1500 and the RJ-45 connector 1200 constitutes a closed circuit.

Therefore, a high (H) level voltage is supplied through the 6 terminal from the outlet connector (modular jack) connected to the outside of the IDC connector 1500, and the low level voltage is supplied through the 3 terminal. When supplied, a forward voltage is supplied to the green LED (GD) of the lighting circuit 335 so that the green LED (GD) is turned on.

If the 3rd or 6th terminal of the IDC connector 1500 and the 3rd or 6th terminal of the RJ-45 type connector 1200 are not properly connected (e.g., the 3rd terminal of the IDC connector and When terminal 6 of the RJ-45 connector is connected) A reverse voltage is applied to the green LED (GD) of the lighting circuit 335 and the green LED (GD) is turned off.

That is, in the prior art, there is a disadvantage in that no status signal or alarm is given to an operator when a wiring failure occurs.

In addition, in the prior art, only defective wiring for specific terminals (terminals 3 and 6) of the IDC connector and the RJ-45 type connector could be confirmed. For example, if a UTP cable is defective at the 1st and 2nd terminals, the 4th and 5th terminals, or the 7th and 8th terminals of the IDC connector and RJ-45 type connector, the operator will Could not be confirmed.

Figure 6 shows the UTP cable connection inspection device of the present invention.
