Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a terminal block used for wiring connection of input/output signals in equipment, monitoring panels, etc., particularly for relaying.

(Prior art) Conventionally, terminal blocks used for relaying input/output signals are
The one shown in FIG. 7 is common.

This terminal block a is made of an insulating material and is provided with a central partition wall C extending in the longitudinal direction, and a terminal partition wall d provided across the partition wall C/, and between the adjacent partition walls 6. A terminal fitting e is provided, and a terminal screw f is attached to both ends of the terminal fitting e with one side of the central partition wall C as an input side, and a terminal screw g is attached with the other side as an output side.

Then, a symbol plate and a transparent cover k are fitted onto the central partition wall C, and one or more electric wires are fixed to the metal fittings e by the terminal screw fog directly or via crimp terminals, or by soldering. It's attached.

Recently, with the spread of office equipment such as computers and personal computers, cables with connectors are being used more frequently. This connector is easy to attach and detach, but if you want to change the distribution of signal lines, you need to disassemble the connector and
We will discuss by connecting the wires by soldering.

(Problems to be Solved by the Invention) By the way, in order to output or relay one input signal as an output signal from a plurality of terminals as described above, a plurality of electric wires or crimp terminals are inserted into one terminal, They are forced to be fixed with terminal screws or soldered, which is very time-consuming and poses a safety problem.

This invention was devised by paying attention to the above-mentioned actual situation, and its purpose is to relay human power words to multiple outputs/terminals, and to arbitrarily select the output terminal. Our aim is to provide flexible terminal blocks that can

(Means for Solving the Problems) In order to achieve the above object, the present invention has taken the following technical means.

That is, the present invention includes a group of terminals for connecting input signals;
A terminal block in which groups of terminals for connecting output signals are arranged in opposing positions, is characterized by the fact that a signal pattern converter with multiple dials is placed between each terminal group for input signals and output signals. .

(Function) According to the present invention, when the relay father selectively outputs one of the input signals to a plurality of output terminals using the signal pattern converter (changes the destination of the signal), the dial is rotated. This is done by connecting to any output terminal. In other words, by rotating the dial and aligning the pointer with any terminal of output terminals A to H..., the human input signal connected to terminal 1 changes the destination of the signal and outputs it from that terminal. can be done.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show embodiments of the present invention, in which a terminal block 1 includes a main body 2 made of an insulating material, terminal fittings 3.4,
The signal pattern converter 8 includes an input terminal screw 5, an output terminal screw 6, and a dial 7.

A converter storage chamber 9 is formed in the center of the stand main body 2,
Terminal spacing walls 10, 11 are formed at regular intervals on both sides in the width direction, and between one of the partition walls 10, an input side terminal fitting 3 is fitted and an input side terminal screw 5 is attached to connect the input signal line. Terminal groups ■ to ■ are formed, and between the other partition wall 11, an output side terminal fitting 4 is fitted and an output side terminal screw 6 is attached, forming a terminal group A to H for connecting the output signal line. It depends.

As illustrated in FIG. 3, the signal pattern converter 8 is configured such that a rotary contact terminal 14 formed at the tip of a rotor 13 fixed to a rotary shaft member is connected to One more fixed contact terminal than the number of output terminals arranged on the circumference 1
5 (including OFF), eight of them are arranged in the converter housing chamber 9, and the rotary shaft +21 end protrudes through the top plate, and the rotary shaft 12 end has a dial 7. are fixed and layered. Note that the rotating contacts 14 are connected to each input terminal fitting 3, and each fixed contact terminal]
5 is connected to each output side terminal fitting 4 of the output terminals A to H, respectively.

Of the fixed contact terminals L5, OF1=' prevents the input signal from being relayed to any of the terminal fittings 4, and is not connected to any of the output terminals A to H.

Further, on the upper surface of the top plate of the converter storage chamber 9, around each dial 7, positions A to H and O of each fixed contact terminal]5 are provided.
FF is displayed.

According to the above embodiment, the pointer of the dial 7 of the converter 8 corresponding to each of the input terminals ■ to ■ is connected to the output terminal A-
By matching the display that matches H, the destination of the input signals of each input terminal 1 to 2 can be selectively changed to the position b of each output terminal A-)1.

Furthermore, signals from multiple input terminals can be relayed to one output terminal.

Therefore, the input side terminal group ■～■ and the output side terminal group A-H
By connecting the outputs in reverse, one input signal can be output from multiple terminals in the same diagram. For example, when all the dials 7 of each signal pattern converter 8 are set to A and an input signal is received at terminal A, it is possible to simultaneously output the signal to all of the terminal groups (1) to (2).

FIG. 4 shows a first usage example of the above embodiment, in which a connector 16.
The terminal block 1 can be used as a signal converter by connecting the terminals of the connector cables 18 and 19 to which the terminal block 17 is connected.

0, the wiring inside the panel is connected to the input side, and the other end of the connector cable 22 with the connector 21 connected to one end is connected to the output side terminal group, and it can be used as a terminal block for outputting the connector cable inside the panel. It is easy to use.

In addition, in Fig. 5, the wiring inside the panel is connected to the output side terminal group of the terminal block 1, and the connector cable 22 is connected to the input terminal group.
By connecting, it can be used as a terminal block for inputting the FF120 internal connector cable.
