Description

Technical Field

[0001] This utility model relates to the field of relay technology, and more specifically, to a relay with auxiliary monitoring signal feedback. Background Technology

[0002] With the development of new energy technologies such as photovoltaic energy storage, solar energy, and wind energy, the safety conditions for the use of power relays are becoming increasingly stringent, and the service life of the relays themselves is also being required to be longer. Therefore, it is necessary to propose a relay with auxiliary monitoring signal feedback.

[0003] Existing relays lack auxiliary contact monitoring and disconnection capabilities, resulting in low safety and reliability during use. This fails to meet customer and market demands, diminishes core competitiveness, and causes frequent contact misalignment, significantly increasing contact silver layer wear and contact adhesion risks. Consequently, the lifespan of relay products is reduced, failing to meet customer requirements.

[0004] Therefore, those skilled in the art have provided a relay with auxiliary monitoring signal feedback to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a relay with auxiliary monitoring signal feedback, including a base, and further comprising:

[0006] A magnetic system is fixedly installed inside the base;

[0007] The main load circuit system is fixedly installed inside the base;

[0008] A pusher plate is located above the base, and the upper surface of the base is provided with a mounting groove for mounting the pusher plate;

[0009] An auxiliary contact assembly is disposed inside the base.

[0010] As a further improvement to this technical solution, the magnetic system includes a yoke, an iron core, a frame, and a coil.

[0011] As a further improvement to this technical solution, the main load circuit system includes a movable piece and a stationary piece, and both the movable piece and the stationary piece are provided with contacts inside.

[0012] As a further improvement to this technical solution, the auxiliary contact assembly includes an auxiliary moving spring and an auxiliary stationary plate, which are respectively fixedly installed inside the base.

[0013] As a further improvement to this technical solution, an auxiliary moving contact is fixedly installed inside the auxiliary moving spring, and an auxiliary stationary contact is fixedly installed inside the auxiliary stationary plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this type of relay with auxiliary monitoring signal feedback, the auxiliary contact assembly allows for easy assembly of the entire relay. Simply install the magnetic system and the main load circuit system into the base. When the relay is powered, the magnetic system's conversion from electric to magnetic force connects the main load circuit. At this point, the push plate moves downwards, and the auxiliary contact assembly connects accordingly, enabling normal signal feedback. When the magnetic system is de-energized, the main load circuit disconnects, and the auxiliary contact assembly also disconnects synchronously. However, if the main load circuit remains open even after the magnetic system is de-energized, the auxiliary contact assembly will not disconnect, indicating that the main load circuit has not disconnected properly and the contacts inside are stuck together. In this case, the auxiliary contact assembly will provide a feedback signal, forcibly cutting off the current in the main load circuit. This protects the circuit from long-term or abnormal safety incidents that could lead to accidents. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 4As shown, this embodiment provides a relay with auxiliary monitoring signal feedback, including a base 1, and further including:

[0024] Magnetic system 2 is fixedly installed inside base 1;

[0025] The main load circuit system 8 is fixedly installed inside the base 1;

[0026] The pusher plate 3 is located above the base 1, and the upper surface of the base 1 is provided with a mounting groove for mounting the pusher plate 3;

[0027] The auxiliary contact assembly is located inside the base 1.

[0028] The working principle is as follows: When assembling the relay as a whole, simply assemble the magnetic system 2 and the main load circuit system 8 into the base 1. When the relay is powered, the magnetic system 2 switches from electric to magnetic force, which connects the main load circuit system 8. At this time, the pusher 3 will push downward, causing the auxiliary moving spring 4 to move synchronously. The auxiliary moving spring 4 then causes the auxiliary moving contact 5 to move synchronously. When the auxiliary moving contact 5 and the auxiliary stationary contact 7 come into contact, the signal feedback can function normally. When the magnetic system 2 is de-energized, the main load circuit system 8 will also disconnect. At this time, the auxiliary moving contact 5 and the auxiliary stationary contact 7 will also disconnect synchronously. If the magnetic system 2 is de-energized but the main load circuit system 8 is not disconnected, the auxiliary moving contact 5 and the auxiliary stationary contact 7 will not disconnect either, indicating that the main load circuit system 8 has not disconnected normally and the contacts inside the main load circuit system 8 are stuck together. At this time, the auxiliary contact assembly will provide a feedback signal, forcibly cutting off the current of the main load circuit system 8, thereby protecting the circuit from long-term or abnormal safety incidents that could lead to accidents.

[0029] In order for the relay to function properly, the magnetic system 2 includes a yoke, an iron core, a frame, and a coil. When the magnetic system 2 needs to be installed, the frame, coil, iron core, and yoke are first fixedly assembled. Then the magnetic system 2 can be assembled and fixedly installed on the base 1, so that the relay can function properly.

[0030] Considering that the main load circuit system 8 needs to be installed when using the relay, the main load circuit system 8 includes a movable piece and a stationary piece. Both the movable piece and the stationary piece are equipped with contacts. When the main load circuit system 8 needs to be installed, simply fix the movable piece and the stationary piece inside the base 1 first. At this time, the movable piece, the stationary piece, and the contacts can be fixedly installed, thereby completing the installation of the main load circuit system 8. Then, the magnetic system 2 and the main load circuit system 8 can be fixedly installed, so that the relay can be used normally.

[0031] To enable the auxiliary moving contact 5 and the auxiliary stationary contact 7 to close and open, the auxiliary contact assembly includes an auxiliary moving spring 4 and an auxiliary stationary plate 6, which are respectively fixedly installed inside the base 1. When the relay is powered, the magnetic system 2 switches from electric to magnetic force, which connects the main load circuit system 8. At this time, the push plate 3 pushes downward, causing the auxiliary moving spring 4 to move synchronously. The auxiliary moving spring 4 then causes the auxiliary moving contact 5 to move synchronously. When the auxiliary moving contact 5 and the auxiliary stationary contact 7 are closed, the signal feedback can work normally. When the magnetic system 2 is de-energized, the main load circuit system 8 will also disconnect synchronously. At this time, the auxiliary moving spring 4 will drive the auxiliary moving contact 5 to move synchronously, thereby disconnecting the auxiliary moving contact 5 and the auxiliary stationary contact 7. Through the setting of the push plate 3 and the auxiliary moving spring 4, the auxiliary moving contact 5 and the auxiliary stationary contact 7 can be effectively closed and opened.

[0032] In order to forcibly cut off the current of the main load circuit system 8, an auxiliary moving contact 5 is fixedly installed inside the auxiliary moving spring 4, and an auxiliary stationary contact 7 is fixedly installed inside the auxiliary stationary contact 6. When the magnetic system 2 is de-energized, the main load circuit system 8 is not disconnected. At this time, the auxiliary moving contact 5 and the auxiliary stationary contact 7 will not disconnect, indicating that the main load circuit system 8 has not disconnected normally and the contacts inside the main load circuit system 8 are stuck together. At this time, the auxiliary contact assembly will feed back a signal, thereby forcibly cutting off the current of the main load circuit system 8, protecting the circuit from long-term or abnormal safety incidents that could lead to safety accidents. The closed and open states of the auxiliary moving contact 5 and the auxiliary stationary contact 7 can be used to determine whether the main load circuit system 8 is operating normally, and can effectively cut off the current of the main load circuit system 8, thus effectively improving the overall safety and service life of the relay.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
