Description

[Detailed description of the invention] (Field of industrial application) The present invention consists of fitting a main body metal plate with terminals protruding on both sides into an insulating case, and forming terminals in the main body metal plate below the holes on the top surface of the case. Continuation fittings for multiple terminal blocks are designed specifically for multiple terminal blocks that face the window hole and connect multiple insulating cases in a manner that allows them to be freely separated.The connection between adjacent terminal blocks is made by branching the wiring to the terminals. The purpose is to allow processing to be performed within a multiple terminal block without the need for

(Prior art) In a series terminal block, when it is necessary to connect a common line to each terminal of adjacent terminal blocks, the connecting end of the common line is divided into several sections and connected to the required terminals. There is no conductive metal fitting that can be used exclusively for multiple terminal blocks.

(Problem that the invention aims to solve) Connected terminal blocks are often installed on power distribution boards and used for connecting signal wiring, power wiring for motor drives, etc., and it is difficult to connect common lines to adjacent terminal blocks. Often connected.

The stand is assembled by fitting these connecting tubes and fitting holes.

The conduction fitting of the present invention is an inverted U as shown in Figure 1.
shaped jumper 21 and inverted U-shaped lock bar 28
It consists of.

As shown in FIGS. 4 and 5, the jumper 21 is inserted across the holes 14, 14 of the adjacent insulating cases 5 of the connected terminal block, and is inserted between the adjacent main body metal plates 1, 1.
It consists of a gate-shaped plate 23 provided with a pair of legs 22 that are fitted into the holes of the insulating case 5, and a connecting piece 24 that connects the central part of the upper end of the gate-shaped plate 23. and has a width that allows two separate pieces to be inserted in parallel into the window holes 3, 3a of the main body metal plate 1,
and an inward protrusion 25 at the lower part of each of the legs 22.
Provided by bending. Also, the two legs 2 of the portal board 23
Stoppers 26, 26 are in contact with the hole edges of the upper window holes 3 of the adjacent main body metal plates 1 between the protruding base ends of the two.
will be established. An insertion guide that is slightly bent in the direction of the connecting piece 24 is formed at the lower end of the leg part 22.

The lock bar 28 is connected to the gap 27 on both sides of the connecting piece 24.
It has an inverted U-shape that can be inserted between the gate-shaped plates 23, 23 with a tight fit, and a tip 29 is provided at the lower end of each of the two parallel leg pieces, and the legs are inserted above the tip. It has a shape that pushes the inward protrusion 25 of the portion 23 outward.
