器を提供することを目的とする。Relays installed in places where there is a high possibility of receiving shocks from the outside, such as on ships or vehicles, must have a special configuration that prevents malfunctions caused by such shocks and ensures reliable operation only in response to commands from the outside. is necessary. For this purpose, the movable part is statically and dynamically balanced so that the movable part does not vibrate due to external shocks. However, even this is insufficient, and methods have been implemented to proactively suppress malfunctions, but in this case, the structure becomes complicated and there is also the drawback that reliability is low for long-term use. SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and provide a shock-resistant relay with a simple structure and good performance.

振り子により抑止するものである。In order to achieve this object, the present invention provides a relay having a structure in which an insulating rod biased by a spring is locked by a tripping lever, and a pendulum having a vibration period shorter than that of the tripping lever. The mechanism is characterized in that when a shock is received, the rotation of the pendulum prevents the tripping lever from rotating in the tripping direction, and the tripping lever vibrates due to the impact and detaches from the insulating rod. This is suppressed by the pendulum.

ル７を加熱する。FIG. 1 is a diagram showing the principle of a shock-resistant thermal overload relay according to the present invention. In FIG. 1, normally closed contacts 1 and 1' are pushed open by the sharp tip of the insulating rod 2, and send an operating signal to the outside. The insulating rod 2 has its rear end connected to the spring 3.
Although it is urged to protrude upward, it is prevented by locking the pawl 5a of the tripping lever 5 to a small wheel 4 attached to the protrusion 2a on the side surface. The tripping lever 5 is supported by a pin 6 on the base plate. 7 is bimetal,
A heater 8 heats the bimetal 7 by passing a current related to the circuit current.

うに９を支点とする振り子１０を設ける。The above is the configuration of a conventional thermal overload relay. The operation of this Momodenki is that when an overload current flows through the circuit, it heats the bimetal 7, bends it, and pushes the lower end of the tripping lever 5 to the left. The tripping lever 5 rotates clockwise about the pin 6, the pawl 5a comes off the small wheel 4, the insulating rod 2 is pushed by the spring 3 and protrudes, and the normally closed contacts 1, 1' are pushed open. In the above configuration, the tripping lever 5 is balanced around the pin 6 as a fulcrum so that it does not rotate freely due to external impact, but if it receives an excessive impact, a slight deviation will generate a rotational force, causing the claw 5a to come off. malfunction may occur. In order to prevent the above-mentioned malfunction, in the present invention, in addition to the above-mentioned structure, a pendulum 10 having a fulcrum 9 as shown in FIG. 1 is provided.

大きい。This pendulum 10 is provided with bifurcated protrusions 11 and 11' on the sides, and 13 and 14 are weak springs for keeping the pendulum 10 in balance. The vibration period of the pendulum 10 is made shorter than that of the tripping lever 5. Therefore, when an impact is applied to the relay, the pendulum 10 causes a simple vibration as shown in FIG. 2 or 3, and the projections 11, 11' interfere with the projection 12 provided on the back of the trip lever 5. That is, since the vibration period of the tripping lever 5 is relatively long, it vibrates and the pawl 5
While the lever a is about to come off, the short-cycle pendulum 10 interferes with it, inhibits the clockwise rotation of the tripping lever 5, and prevents malfunction. Tripping lever 5 due to overcurrent
When the pendulum rotates clockwise, the protrusion 12 escapes between the bifurcated protrusions 11 and 11' of the pendulum 10, so the addition of the pendulum 10 does not interfere with the normal operation of the relay.
As described above, the shock-resistant general electric appliance according to the present invention actively suppresses the vibration of the trip lever due to large external shocks by simply adding a simple pendulum to the conventional relay, and malfunctions due to the shock of the relay. The effect is great because it prevents this.
