Abstract

PROBLEM TO BE SOLVED: To lengthen the distance between terminals without changing the length of a terminal block by installing a second conductor which is in a different electric state from a first conductor on a second insulator which is different in horizontal height from a first insulator where the first conductor is installed and then fastening each conductor with a different bolt. SOLUTION: An insulator 3 is a device to install a conductor 2 and a tightening bolt 1 is to be used to fasten the conductor on the insulator. An insulator 3A, being located at a different horizontal height from the insulator 3, is a device to install a conductor 2A on which is in a different electric state from the conductor 2. The conductors 2 and 2A are tightened by different tightening bolts 1 and 1A to fasten terminals 4 and 4A. By this method, the distance between terminals of a panel wire and an external cable can be made longer without changing the length of the terminal block wherein the panel wire and the external cable are connected.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the terminal block device of the present invention will be described. In FIG. 1, the insulator 3 is a device for attaching the conductor 2, and the tightening bolt 1 is a device for fixing the conductor 2 to the insulator 3. The insulator 3A is a device that is installed at a position different from the horizontal height of the insulator 3 and attaches the conductor 2A having a different electrical state from the conductor 2. Tightening bolt 1A
Is a device for fixing the conductor 2A to the 3A insulator. 2 is a plan view of FIG. Further, in the terminal first device shown in FIG. 3, the insulator 3 is a device for attaching the conductor 2, and the tightening bolt 1 is a device for fixing the conductor 2 to the insulator 3. The insulator 3A is a device that is installed in a direction different from the mounting direction of the insulator 3, for example, deflected from the insulator 3 by an angle θ and that mounts the conductor 2A having a different electrical state from the conductor 2. Tightening bolt 1A connects conductor 2A to insulator 3
It is a device fixed to A. 4 is a partial plan view of FIG.

FIG. 2 shows an external wire cable consisting of a terminal 4, a terminal treatment portion 5 and a cable 6 for tightening an external cable, and of the three terminal attaching portions consisting of a bolt 1, a conductor 2 and an insulator 3, the middle terminal attaching portion is the other one. Compared to the case where two terminal mounting parts are arranged, they are displaced upward, connected to the conductor 2 with the tightening bolt 1 and further connected to the extension lines 7 and 7A. The distance of the part 5 can be widened. Similarly, 5A is a terminal processing unit, and 6A is a cable.

FIG. 3 shows an example in which three insulators 3, 3A, 3B are attached at an angle θ, for example 120 degrees, by an insulator attachment seat 8 for attaching the insulator 3 to the frame of the board. Not only can the distance of the terminal processing unit 5 be widened, but also the distance between the three cables 6 becomes the same, so that a mutual induction canceling effect can be obtained.

[0008]

As described above, according to the present invention, in the terminal block for connecting the in-board cable and the external cable, the terminal mounting portion composed of the tightening bolt, the conductor, and the insulator is not arranged directly beside the conventional terminal block, but the terminal mounting portion is disposed. By arranging each of them in the vertical direction, it is possible to widen the distance between the terminal processing portions of the external cable without increasing the terminal block length.
