It is characterized in that was example.

[0006]

In the two-stage connection terminal block device of the present invention, the socket terminal block has a flat portion on its upper surface and stepped base portions on both sides, and is parallel to the outside of the flat portion of the socket terminal block. Arrange the jack insertion holes, arrange the inner jack insertion holes in parallel with the outer jack insertion holes on the inside of the flat part, arrange the external wire connection terminals on the base part, and connect to the external wiring circuit, Connect the external wire connection terminal and the outer jack insertion hole or the inner jack insertion hole with the internal connection wire, insert the lower relay directly into the inner jack insertion hole and install it, and then install the upper relay in two steps above the lower relay. It is characterized in that the upper relay is attached to the configuration, the upper relay is fixed to the socket terminal block by the upper socket terminal block, and the upper relay is prevented from being detached from the upper socket terminal block by the attachment / detachment prevention metal fitting.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the two-stage connection terminal block device of the present invention will be described below. In FIG. 1, the socket terminal block 1 has a flat part 1a on the upper surface and step-like base parts 1b on both sides. The outer jack insertion holes 5 are arranged parallel to each other outside the flat portion 1a of the socket terminal block 1. The inner jack insertion holes 4 are arranged inside the flat portion 1a in parallel with the outer jack insertion holes 5. The external line connecting terminals 2 are arranged and provided on the pedestal portion 1b and are connected to an external wiring circuit.
The internal connecting wire 2 a connects the external wire connecting terminal 2 and the outer jack inserting hole 5 or the inner jack inserting hole 4. The lower relay 6 is directly inserted and attached to the inner jack insertion hole 4, and the upper relay 7 is attached to the upper portion of the lower relay 6 in a two-stage configuration. The upper socket terminal block 8 is a mounting table for fixing the upper joint 7 to the socket terminal block 1. The attachment / detachment portion prevention fitting 9 is a fitting for preventing the upper relay 7 from being attached / detached from the upper socket terminal block 8. 2 is a plan view of FIG. 1, and 3 is a frame mounting hole.

That is, FIG. 1 shows a two-stage connection type socket terminal block 1, an external connection terminal 2, a frame mounting hole 3 for the terminal block, an inner jack insertion hole 4 and an outer jack insertion hole 5.
Is represented. Power lines of the upper relay 7 and the lower relay 6 are also connected inside the terminal block between the respective insertion holes and the respective external connection terminals 2.

By providing the socket terminal block having the above-described structure, when it becomes necessary to add a contact amplifying relay to the lower relay 6, the upper socket terminal block 8 to which the upper relay 7 is connected is connected. You can add a relay by inserting the jack into the existing terminal block.

Reference numeral 9 is a metal attachment / detachment member for preventing the additionally attached upper relay 7 from falling due to vibration or the like. 2 is a plan view of FIG. 1, 4 is a jack insertion hole of the lower relay 6, and 5 is a jack insertion hole 3 for the upper relay terminal block, which is a frame mounting hole. FIG. 3 is a circuit diagram of a two-stage connection type socket terminal block 1, where A is an area showing the lower relay 6 and its socket terminal block 1, and B is an upper relay 7.
And the socket terminal block 8, and the area between A and B is connected by a jack and its connection hole at connection points l to v. a to v are connection points of jacks and pins of the socket terminal block. Further, between the connection points a to l and b to m, that is, in the power lines of the upper relay 7 and the lower relay 6, the jack of the upper socket terminal block 8 is inserted into the socket terminal block 1 of the lower two-stage connection type. Sometimes connected automatically. l '~
Reference symbol v'denotes a connection point between the upper relay 7 and the upper socket terminal block 8 for jacks and pins.

Reference numerals 11 to 30 denote external wire terminals of the lower socket terminal block. According to the above-described embodiment, it is not necessary to attach an additional relay at a distant position, the relay can be easily attached to the upper portion of the relay where contact amplification occurs, and the power supply crossover wiring is also unnecessary.

Further, when the relay is added, the control power supply can be made uninterruptible and can be connected without a power failure. Even if a relay other than the relay for amplifying contacts is added, if the two-stage connection type terminal block is provided and the power line connection jack of the upper relay socket terminal block can be removed, that is, point 1 If it is not connected, it can be used as a relay for other purposes.

[0013]

According to the present invention, the mounting of the additional relay can be dealt with by space saving, labor saving, and wiring saving, and moreover, it can be performed without a power failure of the control power supply.
