Description

[Detailed description of the invention] (Industrial application field) This invention improves the connection device for multiple terminal blocks, and makes it easy to cut the connecting rod to the appropriate size, whose length must be changed depending on the number of vertical rows of terminal blocks. The length can be easily adjusted and fixed using synthetic resin pipes.

(Prior Art) It has been common practice in the past to pass a metal connecting rod through a plurality of terminal blocks, fixing both ends thereof, and attaching the connecting terminal blocks to a board or the like. However, in order to do this, as shown in FIG. As shown in Figure 4, a screw c is formed at the end of the metal wire connecting rod b, and the terminal block or end plate d is
Fit the nut e in a non-rotatable manner, and tighten the screw c at the end.
is connected by screwing it into the nut e, and in both cases, the mounting hole f formed in the terminal block or end plate c is
The connecting rods a and b are sometimes used in parallel with a small distance between them. However, connecting rod a,
Since b is conductive, it is necessary to completely insulate the terminal block, and if the number of terminal blocks connected is small, a tool such as a metal saw must be used for cutting. If a connecting rod is provided, a new thread must be cut after cutting, and if a long connecting rod is required, a short connecting rod will not suffice.

(Problems to be Solved by the Invention) The problem to be solved by the present invention is to develop a connecting device using a connecting rod that has a solution that eliminates the drawbacks of the prior art described above.

(Means for Solving the Problems) The present invention aims to solve the problems mentioned in the previous section, and specifically, it is a method for inserting multiple terminal blocks into a terminal block stacked in tandem so that both terminals are The connecting rod to be fixed to the terminal block or end plate is a synthetic resin pipe that can be easily cut to the appropriate size, and a headed tightening screw rod is screwed into the center hole of the pipe from the outside of the terminal block or end plate at both ends. The present invention relates to a connecting device for connecting a plurality of terminal blocks, characterized in that the above-mentioned fixation is performed by.

A preferred embodiment of the invention is described in the following section.

(Embodiment) FIG. 1 is a perspective view of this embodiment, and FIG. 2 is a partially cutaway plan view of the same.

In the figure, 1 is a connecting rod made of a synthetic resin pipe that can be easily cut with a nearby tool such as a knife or a safety razor blade, and 2 is a terminal block with a connecting rod insertion tube 3. Use pieces stacked in vertical rows. Reference numeral 4 denotes an end plate formed to match the terminal block 2, and a mounting piece 6 bent at 90 degrees at the lower end is formed to provide long mounting holes 7, 7.

In this embodiment, as shown in FIG. 2, the end plates 4, 4 are stacked on both ends, and the required number of terminal blocks 2 are connected in tandem between them, and the connecting rod insertion hole pipe 3 and the end plate 4 are While matching the provided through hole 5 (Fig. 2),
Cut the connecting rod 1 made of synthetic resin pipe according to its length, pass the connecting rod 1 through the connecting rod insertion tube 3 provided on the terminal block 2, and then fit both ends into the through holes 5 of the end plate 4. , a screw rod 8 with a head that closes the through hole 5
is fitted into the through hole 5 and screwed into the center hole of the connecting rod 1 to fix it.

(Function) Since the present invention uses the connecting rod 1 made of synthetic resin pipe by cutting it to the appropriate size, it is necessary to procure saw blades and the like that are not available at the work site unlike conventional metal connecting rods. Since the terminal blocks 2 can be easily cut to the required length with a knife or the like on hand, any number of terminal blocks 2 can be connected without the need for a saw blade.

(Effects) In the present invention, the connecting rod 1, which is inserted into the terminal block 2 stacked in a column and fixed at both ends to the terminal block 2 or the end plate 4, is a synthetic resin pipe that can be easily cut to an appropriate size, and The terminal block or end plate is fixed by a headed tightening screw rod 8 that is screwed into the center hole of the connecting rod 1 from the outside, and the connecting rod 1 can be easily cut to the appropriate size at the work site and is easy to use. The synthetic resin pipe is not only easy to use and has excellent electrical insulation properties, but is also lightweight and convenient to carry. By screwing and fixing the threaded rod 8 engaged with the threaded rod 8 into the center of the connecting rod 1 made of the synthetic resin pipe, the connection can be made advantageous.
