Here, the communication cable 110 is connected through a straight connection, as shown in FIG. 5, where the first pin 121a(1) of the first plug 120a is connected to the first pin 121a(1) of the second plug 120b. It is connected to the pin 121b(1), and the second pin 121a(2) of the first plug 120a is connected to the second pin 121b(2) of the second plug 120b. This means a configuration in which the pin numbers of each communication line 111 connected between the plug 120a and the second plug 120b are connected the same.

This straight connection method is mainly used to connect a host device to a client device. For example, when connecting a PC device to a hub, a straight connection connects the hub to a router. It is used in connection cases, etc.

As shown in FIG. 6, the crossover connection method is when the reception line (Tx) and the transmission line (Rx) of at least one pair of communication lines 110 constituting the communication cable 110 are connected to cross each other.

In the crossover connection method, according to the standard EIA/TIA-568B, the first pin of the first plug (120a) is connected to the third pin of the second plug (120b), and the second pin of the first plug (120a) is connected to the third pin of the second plug (120b). 2 is connected to the 6th pin of the plug 120b), the 3rd pin of the first plug 120a is connected to the first pin of the 2nd plug 120b), and the 6th pin of the first plug 120a is connected to the 2nd plug. It can be connected to the second pin of 120b). The crossover connection pin connection method may vary depending on wiring standards.

This crossover connection method is mainly used to directly connect two different host devices. For example, the crossover connection method connects from a PC device to a PC device in a PoE (Power Over Ethernet) network system. In this case, it is used when connecting from a router to a router, when connecting from a hub to a hub, or when connecting from a PC device to a router.

Figure 7 shows a communication line connection method when the communication cable 110 and plug 120 of the communication patch cord 100 are of the RJ 11 standard. Mainly, the RJ 11 connection method is applied when a communication patch cord is used as a telephone line.

The communication line connection method of the RJ 11 standard is the straight connection method shown in FIG. 5, with the third communication line (111(3)), the fourth communication line (111(4)), the fifth communication line (111(5)), and the sixth communication line. When (111(6)) is straight connected, that is, the third pin of the first plug 120a is connected to the third pin of the second plug 120b, and the fourth pin of the first plug 120a is connected to the third pin of the second plug 120b. 2 is connected to the fourth pin of the plug 120b, the fifth pin of the first plug 120a is connected to the fifth pin of the second plug 120b, and the sixth pin of the first plug 120a is connected to the fourth pin of the second plug 120b. 2 This is a connection method configured to connect to the sixth pin of the plug 120b.

Referring again to FIGS. 2 and 3, the integrated connection state identification unit 600 constituting the communication patch cord tester 1000 according to the present invention distinguishes the integrated connection state according to the wiring method of the communication cable described above. In order to identify it, it is configured to include a first integrated connection status identification unit 600a to indicate the integrated connection status of the straight connection and a second integrated connection status identification unit 600b to indicate the integrated connection status of the crossover connection. It can be.

Here, three or more integrated connection status identification units 600 may be provided to correspond to various wiring methods of the communication cable 110. Additionally, three or more wiring methods may be displayed on the two integrated connection status identification units 600. That is, as shown in Figure 2, one LED indicating the integrated connection status of the straight connection type patch cord, which is the communication cable 110 most commonly used in patch cords of indoor communication systems, a crossover connection, and RJ11 One LED can be provided to display the integrated connection status of the connection type patch cord.

Therefore, the first integrated connection status identification unit 600a turns on when the plurality of communication lines 111 are connected in a straight connection method and the connection status of each of the plurality of communication lines 111 is normal, or the first integrated connection status identification unit 600a lights up or displays each of the plurality of communication lines 111 The LED may light in a specific color to indicate that the connection status is normal. In addition, the second integrated connection status identification unit 600b lights up when the plurality of communication lines 111 are connected in a crossover connection according to a predetermined connection combination and the connection status of each of the plurality of communication lines 111 is normal. The LED may emit a specific color to indicate that the connection status of each of the communication lines 111 is normal.

The second integrated connection status identification unit 600b for identifying the crossover connection in the communication patch cord tester 1000 according to the present invention can be configured to enable identification of the integrated connection status of the RJ 11 communication cable 110. .

That is, the microcontroller of the tester uses the third communication line 111(3), fourth communication line 111(4), and fifth communication line 111(5) shown in FIG. 5, which is a communication line connection method of the RJ 11 standard. If the sixth communication line 111(6) is connected straight and forms a closed circuit through test power application, that is, the third to sixth pins of the first plug 120a are connected to the third pin of the second plug 120b. to 6th pins, but if it is determined that the 1st, 2nd, 7th, and 8th pins do not form a closed circuit, the RJ 11 communication cable 110 is mounted on the tester, and each communication line It can be judged to be in a normal state.

However, in addition to the third to sixth pins of the first plug 120a and the second plug 120b, a communication line connecting at least one of the first pin, second pin, seventh pin, and eighth pin forms a closed circuit. If the corresponding LED element lights up or emits a specific color indicating that the connection status is normal, this means that the communication cable that makes up the patch cord is not an RJ 11 communication cable, but a straight communication cable (110) according to T-568A and T-568B. Although it is a communication cable consisting of a straight connection and a crossover connection, it can be judged as a bad connection.

In an embodiment of the present invention, the RJ 11 communication cable 110 is configured to indicate a normal connection through the second integrated connection status identification unit 600b, but if the connection status of the RJ 11 communication cable 110 is changed to the first integrated connection status When identified by the identification unit 600a, the third communication line 111(3), the fourth communication line 111(4), the fifth communication line 111(5), and the sixth communication line are used in the general UTP communication cable 110. The connection of (111(6)) is normal and the first communication line (111(1)), the second communication line (111(2)), the seventh communication line (111(7)), and the eighth communication line (111(8)) This is because the configuration for differentiating from each other becomes complicated when the connection is defective.

Therefore, when the connection status of each communication line 111 constituting the RJ 11 communication cable 110 is normal, the communication patch cord tester 1000 detects the third to sixth communication lines among the plurality of individual connection status identification units 500. The individual connection state identification units 500(3) to 500(6) corresponding to (111(3) to 111(6)) light up, and the second integrated connection state identification unit 600b lights up or the integrated connection state identification unit 600b turns on. The LED may be configured to emit light in a specific color to indicate that is normal. Also, if the size of the tester is not too large, a separate identification unit can be added to identify the LED element in a normal connection state.

Therefore, the communication patch cord tester 1000 according to the present invention is capable of connecting the first port 300a and the second port 300b without having to separately provide a plurality of connection ports according to the standard or wiring method of the communication cable 110. Since it is configured to test whether a communication line connection is abnormal with only a total of two connection ports, the overall volume of the tester 1000 can be minimized and the configuration can be simplified.

In addition, the communication patch cord tester 1000 according to the present invention is configured to include an LED element, and lights up when there is a short circuit or disconnection of at least one of the plurality of communication lines or connects at least one of the plurality of communication lines. It may further include a connection failure identification unit 800 that emits an LED in a specific color to indicate that the status is abnormal.

As described above, when the plug 120 of the communication patch cord is mounted on the first port 300a and the second port 300b, the microcontroller (MCU) sequentially supplies test power to each communication line 111. And the connection state can be displayed through an LED element provided in each individual connection state identification unit 500 corresponding to the communication line 111 that is in a normal state.

In addition, the microcontroller (MCU) displays the status through the poor connection identification unit 800 when it is determined that at least some of the communication lines of the individual connection status identification units 500 do not form a closed circuit or are short-circuited. In this case, the integrated connection status identification units 600a and 600b may be controlled to light up, blink, or emit light in a specific color.

On the other hand, each communication line 111 constituting the communication cable 110 does not have a connection defect such as a short circuit or disconnection, but when connected using a connection method other than the wire-map method specified in the standard, normal communication may not occur. Since this is not possible, wire map errors specified in standards such as T-568A and T-568B can also be configured to be identified as connection defects.

Therefore, the patch cord tester 1000 for communication according to the present invention is configured to include an LED element, and a wire map error identification unit that lights up, blinks, or emits light in a specific color when there is an error in the wire map of the plurality of communication lines 111. It may be configured to further include (900).

In addition, if there is a wire map error in the connection between at least one communication line 111 and the plug 120 among the plurality of communication lines 111, the microcontroller (MCU) displays the status through the wire map error identification unit 900. You can.

Here, a wire map error occurs when the pin numbers of the first plug (120a) and the second plug (120b) connected to both ends of the communication cable (110) match each other even though the communication cable (110) must be connected in a straight connection method. This may occur if this is not done, or if the communication cable 110 is connected by a crossover connection, the predetermined combination of plug pins for each communication line 111 is different.

Meanwhile, when the wire map error identification unit 900 is displayed in an abnormal state, the integrated connection status identification unit 600 may be displayed in an abnormal state even if there is no disconnection or short circuit of the plurality of communication lines 111. there is. That is, the integrated connection status identification unit 600 can be displayed in a normal state only when there is no short circuit or disconnection in each communication line 111 inside the communication cable 110 and the wire map is normal.
