Description

Indoor communication cable connection device {CONNECTOR FOR INNER COMMUNICATION CABLE}

The present invention relates to an indoor communication cable connection mechanism for connecting and wiring a plurality of indoor communication cables with an external communication network.

With the development of information and communication technology in earnest, various communication facilities were installed as essential options in addition to water and sewage facilities and distribution facilities when building a new building where users reside for work or life.

The communication facility includes a dedicated wiring tray for wiring of communication cables, as well as connection devices such as a hub and a communication sharer that connect indoor communication cables to an external communication network and distribute lines through multiple lines.

As described above, conventional connection devices connect a plurality of communication cables with one external communication network to distribute lines. Therefore, a unique IP is set for each port to which the connector of the communication cable is connected, and when the communication cable is connected to the port, the external communication network and The communication cable is connected to the network so that the user can perform network communication using the terminal of the communication cable.

However, since the port of the conventional connection device has a hole shape into which a connector having a pin structure is simply inserted, if tension is applied to the communication cable after the connector is connected to the port, there is a problem that the connector is easily separated from the port and disconnected.

In order to solve this problem, the port and the connector constitute a lock member such as a connection nut, and when the connector is connected to the port, the lock member is tightened so that the port and the connector are not mechanically separated. However, since the conventional lock members are configured for each connector of the communication cable, in the case of connecting a plurality of communication cables to the connection device, it is inevitable to have to manipulate the lock members as many as the number of communication cables. Moreover, in the case of separating the communication cable from the connection device in order to manage communication equipment such as a connection device and a communication cable, there is also the inconvenience of having to manipulate the lock member by extracting the communication cable in the state of wiring in which a number of communication cables are tangled.

In the end, there is a need for a technology that enables the connector of the communication cable to be mechanically securely fastened by connecting the connector of the communication cable to the port of the connecting device without manually manipulating the lock member, as well as allowing the communication cable to be easily separated from the connecting device when necessary.

1 to 3, the connection device 100 of the present invention includes a communication module having a relay function for electrically connecting an external communication line CL to a plurality of indoor communication cables in parallel, and accommodating the communication module. The first fence 120 seated and slides on the upper surface to cover the housing 110 to which the connector 200 of the communication cable of is connected, and the first fitting hole 113 formed in the housing 110, and the first fitting The second fence 130 seated and slides on the upper surface of the first fence 120 so as to cover the hole 113, and the first and second panels 120 and 130 seated on the upper surface of the second fence 130 A guide light that allows the user to visually grasp the cover 140 that is held and supported so as not to be separated, and the connector 200 that is disposed for each second fitting hole 142 formed in the cover 140 so as to be detachable from the port P It consists of 150 and a power module 160 (see FIG. 7) that supplies power for lighting the guide light 150.

Therefore, if the user manipulates the first and second panels 120 and 130 after connecting the connector 200 of the communication cable to the corresponding port (P), the connector 200 can be firmly held and supported without manual intervention such as nut binding. In addition, in order to disconnect the connector 200 from the port P in order to disconnect the connector 200, only the corresponding connector 200 can be easily disconnected by manipulating the first and second panels 120 and 130. .

Each component of the connection mechanism 100 for this will be described in more detail.

The communication module is configured by setting IPs to a plurality of ports P arranged in a regular matrix structure, and relays communication by connecting the plurality of ports P in parallel to an external communication line CL. In more detail, since the communication module performs the function of a communication router, it constitutes a plurality of ports (P) for connecting a plurality of indoor communication cables, and the port (P) of the present invention has a matrix structure of a certain rule. Are arranged. That is, the plurality of ports P are positioned in a grid arranged in one or more row lines and column lines.

Therefore, when the connector 200 of the communication cable is connected to the port P of the communication module, a plurality of communication cables are arranged in a constant matrix structure on the upper surface of the connection device 100 as shown in FIG. 1.

Meanwhile, since the communication module sets an IP corresponding to the address of the communication network for each port (P), the terminal of the communication cable communicates with the network using the IP set in the corresponding port (P) as an identification code. Since the communication module of the present invention performs a known communication sharing function, a description of a configuration technology for signally connecting an external communication line (CL) and a communication cable, a configuration technology for setting IP, and a hardware structure of the communication module Is omitted.

Since the communication module is formed by combining a circuit board with an external communication line (CL) and a port (P) and various elements, protection from external force is essential. Therefore, the enclosure 110 accommodates and protects the communication module. However, since the port (P) must be able to connect the connector 200 of the communication cable from the outside, the housing 110 is formed with a plurality of first fitting holes 113 along the arrangement of the ports (P). Eventually, when the connector 200 is inserted into the first fitting hole 113, the connector 200 is connected to the port P via the first fitting hole 113.

Subsequently, the first fitting hole 113 is opened in a narrow shape. That is, the upper end of the first fitting hole 113 has a large aperture, and the lower end has a relatively small aperture. Of course, since the lower end of the first fitting hole 113 should not interfere with the connection of the connector 200, the lower end diameter of the first fitting hole 113 exceeds the area of the port P. For reference, the connector 200 connected to the port P has a shape having an upper light-lower end corresponding to the first fitting hole 113 that is narrowly narrowed. That is, the lower portion 210 of the connector 200 inserted into the first fitting hole 113 for connection with the port P has an inverted truncated shape so as to closely engage with the first fitting hole 113. Accordingly, the upper end of the lower part 210 has the same diameter as the upper diameter of the first fitting hole 113, and the lower end of the lower part 210 has the same diameter as the lower end diameter of the first fitting hole 113, and the lower part 210 The upper end of) protrudes to the side of the connector 200 to form a jaw.

On the other hand, since the arrangement of the plurality of first fitting holes 113 forms a constant matrix structure corresponding to the port P, a section where two row lines and two column lines intersect, that is, four first fitting holes ( There are a number of sections around 113), and the housing 110 of the present invention has a guide 114 protruding from the center of the section. In this embodiment, since the first fitting hole 113 is formed in 4 rows and 4 columns, a total of 9 sections are formed, and 9 guides 114 are also formed. Here, the guide 114 guides the sliding of the first fence 120 seated on the upper surface of the enclosure 110 and the second fence 130 seated on the first fence 120 to prevent derailment. The first fence 120 and the second fence 130 are in a stacked state, and the cover 140 is seated and fixed to the upper surface of the guide 114, so that the height of the guide 114 is the first fence 120 and the second fence. It is preferable to correspond to the stacking height of the fence 130.

In the case 110 of the present embodiment, the first electrode body 115 is disposed with a constant width along the circumference of the first fitting hole 113. The first electrode body 115 is installed for each of the plurality of first fitting holes 113, and is electrically connected in parallel with the other neighboring first electrode bodies 115. In addition, the upper surface of the first electrode body 115 is exposed so as to contact the first fence 120. A detailed description of the first electrode body 115 will be described later.
