Conventionally, a large amount of patch cords 300 are connected within a communication room, and it has been a very difficult task to visually distinguish or specify whether or not each connection or connection location is connected.

However, the communication patch cord according to the present invention can provide a lighting indexing function to easily identify the bidirectional connection position of each communication patch cord in the communication room. The communication cable and the communication patch cord 300 according to the present invention are examined in detail.

2 shows a configuration diagram of an embodiment of a communication patch cord 300 according to the present invention, and FIG. 3 shows a cross-sectional view of a communication cable test unit 600 according to an embodiment of the present invention. .

The patch cord 300 for communication according to the present invention may include a communication cable and a pair of plugs 100a and 100b connected to both ends of the communication cable.

And, the patch cord for communication according to the present invention has a feature of further comprising a test unit 600 on the communication cable.

First, a communication cable according to the present invention will be described first.

A communication cable according to the present invention includes at least one communication wire 210; A cable unit 200 having a pair of test wires 230 and a cable jacket surrounding the communication wires 210 and the test wires 230; And two or more test terminals 651 connected to the test wires 230; Includes an optical module 641 mounted to connect a pair of the test wires 230 or two or more test terminals 651, and two or more tests mounted at spaced positions of the cable unit 200 Including a unit 600; the cable unit may be divided into a main connection part 200x connecting two or more test units and a sub-connection part 200y extending outside the pair of test units. .

That is, the patch cord for communication 300 of the present invention is configured with plugs 100a and 100b provided at both ends of the communication cable, and the communication cable of the present invention includes a cable unit 200 and the cable unit 200 in the form of a cable. It may be configured to include a pair of test units 600 mounted on the top, the cable unit 200 is the main connection part (200x) and the sub-connection part (200y) based on the mounting position of the test units (600a, 600b). ) Can be divided.

Test units 600a and 600b may be mounted at inner ends of the sub-connection 200y, and plugs 100a and 100b may be mounted at outer ends.

2 and 3, the test unit 600 includes a substrate 630 on which the test terminal 651 and the optical module 641 are mounted; And it may further include a housing 610 configured to accommodate the substrate 630, the test terminal 651 is exposed and the light of the optical module 641 is configured to be identifiable.

3, the housing includes at least one communication wire 210; A cable unit 200 having a pair of test wires 230 and a cable jacket surrounding the communication wires 210 and the test wires 230 may be passed through and accommodated.

And, as shown in Figure 3, the cable unit 200 is configured in the form of a UTP cable, four pairs constitute a twisted pair, are provided inside the cable jacket, and a pair of test wires 230 are further provided. The test wires 230 are respectively connected to the test terminals 651.

An optical module 641 may be provided between a pair of test terminals 651 constituting each test unit 600. In addition, the number of test terminals provided in the test unit 600 may be two or more, for example, four, etc. so as to be applicable depending on the type of tester or the like.

And, as shown in Figure 2, the test unit 600 is preferably mounted at a predetermined distance in the vicinity of the plug constituting the patch cord for communication. In addition, the test unit may also be additionally provided between the test units at both ends, that is, on the main connection part of the cable unit.

The reason why the test unit 600 is not integrated with the plug constituting the communication patch cord and is spaced apart at a predetermined interval is as follows.

The test unit 600 includes a test terminal 651, an optical module 641, and a substrate 630 on which the test terminal 651 and the optical module 641 are mounted, and constitutes a test unit 600. When the substrate 630 is mounted inside the housing constituting the plug, the length from the communication wire and test wire inlet of the plug to the terminal connection part is lengthened, so that the communication wire 210 in the form of a twisted pair from the cable unit 200 is increased. Since the length at which the twist is unwound becomes longer, and accordingly, the communication characteristics may be adversely affected, a test unit including the test terminal 651 and the substrate 630 on which the optical module 641 is mounted is used as a cable unit ( It can be separated and spaced apart from the plug via the sub-connections 200y at both ends of the 200). This makes it possible to keep twisting between pairs of communication wires connected to each terminal of the plug as close to the terminal as possible.

In addition, patch panels or network switches are generally arranged in a double layer, and each modular jack is also arranged close to each other in a line. Therefore, in such a communication room environment, if the plug of the patch cord is installed with the modular jacks of each device densely installed, the spacing between the plugs is also narrowed, so it is not easy to test using a tester. By separating and separating, the workability of the test work can be improved.

In addition, when the plug of the communication patch cord and the test unit are integrated, the optical module is also provided in a plug installed in a dense manner in the modular jacks of the equipment, so that even when the optical module emits light, there is a problem that it is difficult to easily identify. In particular, since the plug of the communication patch cord is mounted on the modular jack in the horizontal direction, and in the fastened state, only a part of the plug is exposed to the outside of the modular jack to reduce light exposure, so it is not easy to check the light emission state of the optical module near the equipment.

Accordingly, the patch cord for communication according to the present invention employs a method of separating and separating the test unit 600 and the plug 100 using the sub-connector 200y without integrating the test unit 600 and the plug 100.

In addition, if the distance between the test unit 600 and the plug 100 is reviewed, the test unit 600 and the plug 100 are separated without being integrated, but the distance between the test unit 600 and the plug 100 is not integrated. Easy module identification.

That is, if the test unit 600 and the plug 100 are not integrated and separated, but adjacent, for example, if the length of the sub-connection 200y is 30 cm or less, the plug 100 is modular in the horizontal direction. The test unit mounted on the jack and mounted on the inner end of the sub-connection 200y is hung downward so that the optical module of the test unit can be easily identified with the naked eye, and the test unit is placed near the end of the cable unit. It is easy to maintain, such as cabling.

On the other hand, when the test unit 600 and the plug 100 are disposed, for example, separated by tens of centimeters, for example, 50 centimeters or more apart, the test unit 600 is buried between the cable units, making it difficult to identify the optical module. , There is a problem that maintenance of cable units, such as cabling, is not easy.

Therefore, it is preferable that the plugs 100a, 100b and each test unit 600a, 600b of the patch cord for communication according to the present invention are respectively mounted at appropriate positions within approximately 300 millimeters (mm), and more preferably 100 millimeters ( It is preferred to be mounted within mm).

However, it is preferable to apply the location of the test unit 600 on the communication cable constituting the communication patch cord in consideration of the patch cord connection environment or the communication cable diameter.

As shown in FIG. 2, the optical module 641 provided in the test units 600a and 600b is preferably configured to be positioned in a direction opposite to the detachable latches 110a and 110b provided in the housing of the plug. Do.

The plugs (100a, 100b) of the patch cord for communication 300 remain attached to the network switch or the modular jack of the patch panel, etc., and are jammed to facilitate the separation operation when the plugs (100a, 100b) are separated from the modular jack. Detachable latches 110a and 110b with a jaw are provided, and in general, when plugs 100a and 100b are mounted on a network switch or patch panel, the plug 100a so that the detachable latches 110a and 110b face downward. , 100b) may be horizontally fastened in a state in which it is disposed.

Therefore, it is preferable that the optical module is arranged to face forward or upward so that the optical module can be easily identified when the optical module of the test unit emits light in the state in which the plugs 100a and 100b are mounted. Accordingly, the optical module provided in the test unit is disposed in a direction opposite to the detachable latch provided in the housing of the plug so that the light emitting surface of the optical module or the test unit faces forward or upward, and the plugs 100a and 100b Even if the test unit is inclined downward due to its own weight in the state where is mounted, the light emitting surface of the optical module or the test unit is directed forward or upward, so that the light emitting surface of the optical module or the test unit can be easily identified.

The cable unit 200 constituting the communication patch cord shown in FIG. 2 may be a cable unit 200 for short-range communication.

The cable unit 200 shown in FIG. 2 may include a communication wire 210 in the form of a conductor having an insulating layer, and as shown in FIG. 3, a plurality of cable units 200 are provided.
