Description

[Detailed description of the invention] (Technical field to which the invention pertains) The present invention relates to a centralized terminal board that is mounted on a communication equipment rack or the like and has a built-in relay terminal for connecting an in-office coaxial cable, etc., to an internal cable, etc.

(Prior Art) In a conventional centralized terminal board, relay terminals are divided into functions such as pair wire terminals and coaxial wire terminals, and these are arranged and mounted in the height direction.

However, some communication devices are initially designed using pair wires, but are later changed to coaxial wires. In this case, there is no problem if the coaxial line terminal has extra terminals or there is a blank in the communication device, and you can enlarge the centralized terminal board and add more coaxial line terminals, but if you cannot add more coaxial line terminals, reconsider the communication device. However, the disadvantages are that the communication device may have to be separated and mounted on a separate rack.

(Objective of the invention) An object of the invention is to provide a centralized terminal board that eliminates the above-mentioned drawbacks.

(Structure of the invention) The terminal board of the invention includes at least one pair wire terminal for connecting the pair wires, a coaxial wire terminal disposed beside the pair wire terminal for connecting the coaxial wires, and the pair wire terminal for connecting the coaxial wires. the upper or lower part of the terminal or the tongue protruding from the upper and lower parts of the terminal.

(Example) Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a communication device rack equipped with a device function block 2 and a centralized terminal board 3, FIG. 2 is a perspective view showing the configuration of the centralized terminal board 3 in a conventional communication device rack, and FIG. FIG. 1 is a perspective view showing an embodiment of the present invention.

As shown in FIG. 1, a plurality of equipment function blocks 2 are installed in parallel in the height direction on the rack back support 1, and a centralized terminal board 3 is installed at the top or bottom of the rack back support 1. be.

As shown in FIG. 2, in the conventional terminal board 3, terminals 5 for relaying the pair wires 4, terminals 7 for relaying the coaxial wires 6, etc. are arranged in the height direction.

Referring to FIG. 3, in this embodiment, a coaxial cable terminal is attached to the side of the pair line terminal 10 that relays the pair line 4, and the coaxial cable 6 used as an intra-office cable is connected to the pair line terminal 10. tongue piece 9 protruding from the bottom
It is connected to the coaxial cable terminal through the bottom. In this way, since the movement of the coaxial cable 6 is restricted by the tongue piece 9, accidents such as the coaxial cable 6 hitting the terminal portion 11 of the pair wire terminal 10 and causing a short circuit in the pair wire portion 11 can be prevented. This makes it possible to cope with changes in the type of cable due to the electrical characteristics of the line without changing the frame configuration.

Note that the tongue piece 9 protruding from the lower part of the terminal 10 does not need to be formed integrally with the terminal 10, and may protrude from the upper part of the terminal or from the coaxial terminal boundary.

(Effects of the Invention) As described above, the present invention has the advantage of being able to easily accommodate changes in the type of line cable line in a narrow space.
