Definitions
- the present invention relates to a terminal connection device for bridging terminals of electric devices such as a contactor and a switch installed adjacent to each other.
- a terminal connection device that bridges the terminals with a terminal connection conductor is used.
- FIG. 5 shows a wiring diagram of a three-phase electromagnetic contactor using such a terminal connection device.
- Fig. 5 (A) shows the case where the motor is operated by two electromagnetic contactors 1 in forward and reverse directions.
- the terminal connection conductor On the power supply side, the terminal connection conductor is connected between terminals 1 and 1, between terminals 3 and 3, and between terminals 5 and 5. 2, 3, and 4 in the order of phases, that is, the same phase is bridged, and the load side is connected between terminals 2 and 6, between terminals 4 and 4, and between terminals 6 and 2 by terminal connection conductors 5, 6, and 7.
- the connections are bridged in the order of replacement, that is, two phases out of three are replaced.
- a three-phase AC motor can perform forward and reverse rotations by exchanging two phases of the three phases R, S, and T. Therefore, if the left electromagnetic contactor 1 in FIG. 5 (A) is ON, the rotation is forward, and if the right electromagnetic contactor 1 is ON, the rotation is reverse. The same function is obtained even if the power supply and load sides are interchanged.
- FIG. 5 (B) shows a case where two loads A and B are switched by two electromagnetic contactors 1, in which case the power supply side is bridged in phase order.
- the left side of Fig. 5 (B) is turned on, power is supplied to load A, and when the right side is turned on, power is supplied to load B.
- FIG. 5 (C) shows a case where two power supplies A and B are switched by two electromagnetic contactors 1.
- the load side is bridged in phase order.
- FIG. 6 shows an example in which a conventional terminal connection device constitutes a reversible electromagnetic contactor used for forward and reverse operation of a motor.
- FIG. 6 (A) is a side view
- FIG. 6 (B) is a front view.
- two electromagnetic contactors 1 and 1 are installed adjacent to a mounting base 8 and are interlocked by a mechanical interlock device 9 so that the two units are not turned on at the same time.
- the terminal connection conductor 2 in FIG. 6, is different conventional examples showing, for example, the terminal connection conductor 2 in FIG. 6, in which (A) is a side view, (B) is a front view, and (C) is a bottom view.
- the terminal connection conductor 2 is formed of a U-shaped conductor punched from a steel material, and both ends thereof are bent at right angles to form a terminal portion 2a.
- An insulating material 10 is coated between the terminal portions 2a, 2a.
- the insulating material 10 is applied by, for example, dip coating of polyethylene resin or powder insulating coating.
- the conductor configuration of the terminal connection conductor 2 of FIG. 8 is the same as that of FIG.
- the difference is that the insulating material 10 is formed by a tube that contracts due to heat.
- the terminal connection conductor 3 is formed in an ⁇ shape and the terminal connection conductor 6 is formed in a strip shape in order to save space, and is oriented in a direction orthogonal to the terminal connection conductors 2 and 4 or the terminal connection conductors 5 and 7. They are connected as shown in FIG.

- the conventional practice is to avoid the bent part of the conductor as much as possible and to insulate it in the middle of the U-shaped part (see Fig. 8). This has led to the danger of short-circuiting due to the adhesion of conductive foreign matter such as wire scraps to this exposed part and the risk of electric shock due to contact with fingers.
- the terminal connection device for reversible operation shown in FIG. 6 has a problem that wiring errors easily occur because six terminal connection conductors are individually connected.
- the electric insulating element is likely to be deformed when the electric insulating element is molded with a resin, and in some cases, there is a possibility that an inconvenience such that the electric wire does not enter the groove may occur. Furthermore, since the groove of the electric insulating element is open before the electric wire is inserted, the insulation may be deteriorated by dust or the like.
