Description

Technical Field

[0001] This utility model relates to the technical field of relays, and in particular to a relay technology. Background Technology

[0002] Relays are widely used components in industrial equipment. Their working principle utilizes electromagnetic induction. When the coil is energized, a magnetic field is generated, magnetizing the iron core and attracting the armature, causing the contacts to close or open, thus controlling the circuit. When the coil is de-energized, the magnetic field disappears, the armature returns to its original position under the action of the spring, and the contacts also return to their original state. Traditional relays only have two modes: one is energized, conducting the high-voltage circuit; the other is de-energized, disconnecting the high-voltage circuit under the action of the spring. In practical applications, multiple relays are needed to control multiple alternating control circuits, which complicates installation and hinders cost reduction in equipment manufacturing. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a relay that solves the problem that traditional relays can only control the working state of a single high-voltage circuit, resulting in complex equipment structure and high cost.

[0004] To achieve the above objectives, this utility model proposes a relay, including a housing, a lifting electromagnet, an armature magnetic spring, a coil electrode, a high-voltage input electrode, a first high-voltage output electrode, and a second high-voltage output electrode. The first and second high-voltage output electrodes are arranged on the left side of the housing, and the armature magnetic spring is arranged on the right side inside the housing. The bottom of the housing is provided with a lifting electromagnet that is electrically connected to the first and second high-voltage output electrodes respectively by the lifting and lowering of the armature magnetic spring driven by the iron core. A coil electrode for supplying power to the lifting electromagnet is arranged on the side of the housing, and a high-voltage input electrode for electrically connecting to the armature magnetic spring is arranged on the side of the housing.

[0005] Preferably, the lifting electromagnet includes a guide sleeve, a coil, a sliding sleeve, an iron core, and a positioning magnet. The guide sleeve is fixed on the housing, and a positioning magnet is fixed at the bottom of the guide sleeve. The positioning magnet is slidably mounted on the sliding sleeve, and a coil is fixed inside the sliding sleeve. An iron core is fixed inside the coil.

[0006] Preferably, a vertical guide groove is provided around the sliding sleeve, and a ball bearing is provided between the guide groove and the guide sleeve.

[0007] Preferably, the armature magnetic spring includes a spring fixing plate, a lifting kinetic energy magnet, and an armature piece. The spring fixing plate is fixed on the housing, one end of the armature piece is fixed on the spring fixing plate, and the lifting kinetic energy magnet is fixed on the armature piece.

[0008] Preferably, the magnet is fixed in the middle of the armature plate.

[0009] The beneficial effects of this utility model are as follows: By connecting the lifting electromagnet to the positive and negative terminals of the power supply in different ways, the lifting electromagnet can generate attraction or repulsion on the armature magnetic spring, thereby controlling the conduction or disconnection of two sets of circuits. At the same time, in order to compensate for the problem of insufficient magnetic force due to distance, the lifting electromagnet uses repulsion to rise, ensuring that the armature magnetic spring and the lifting electromagnet maintain a close working distance. This helps to reduce the number of relays used in the equipment, reduce installation difficulty and cost, and ensure reliable operation. This relay has three modes, making its application more flexible and adaptable. Attached Figure Description

Detailed Implementation

[0019] See Figure 1 and Figure 2This utility model discloses a relay, comprising a housing 1, a lifting electromagnet 2, an armature magnetic spring 3, a coil electrode 33, a high-voltage input electrode 5, a first high-voltage output electrode 6, and a second high-voltage output electrode 7. The first high-voltage output electrode 6 and the second high-voltage output electrode 7 are located on the left side of the housing 1. By setting the first high-voltage output electrode 6 and the second high-voltage output electrode 7, the relay can control the switching of two sets of high-voltage circuits. The armature magnetic spring 3 is located on the right side inside the housing 1. At the bottom of the housing 1, the armature magnetic spring 3 is driven by a lifting iron core to be electrically connected to the first high-voltage output electrode 6 and the second high-voltage output electrode 7 respectively. The lifting electromagnet 2, when the first high-voltage output electrode 6 contacts the armature magnetic spring 3, the circuit corresponding to the first high-voltage output electrode 6 is turned on; when the second high-voltage output electrode 7 contacts the armature magnetic spring 3, the circuit corresponding to the second high-voltage output electrode 7 is turned on. When the lifting electromagnet 2 pushes the armature magnetic spring 3 upward through magnetic repulsion and contacts the second high-voltage output electrode 7, the lifting electromagnet 2 can automatically rise in order to maintain sufficient repulsion. The housing 1 has coil electrode plates 33 on its side for supplying power to the lifting electromagnet 2, and high-voltage input electrode plates 5 for electrically connecting to the armature magnetic spring 3. It should be noted that, as... Figures 3-5 As shown, the lifting electromagnet 2 includes a guide sleeve 21, a coil 22, a sliding sleeve 23, an iron core 24, and a positioning magnet 25. The guide sleeve 21 is fixed to the housing 1. The positioning magnet 25 is fixed at the bottom of the guide sleeve 21. The sliding sleeve 23 is slidably arranged around the positioning magnet 25. The coil 22 is fixed inside the sliding sleeve 23. The iron core 24 is fixed inside the coil 22. When the armature magnetic spring 3 needs to be pulled downward to attract the coil 22 to energize it, the iron core 24 generates an electromagnetic field under the action of the coil 22, causing the lower end to attract the positioning magnet 25 of the iron core 24. At the same time, the upper end attracts the armature magnetic spring 3, so that the armature magnetic spring 3 and the positioning magnet 25 are attracted. A high-voltage output electrode 6 is electrically connected; when the armature magnetic spring 3 needs to be pushed upward to energize the coil 22, the iron core 24 generates an electromagnetic field under the action of the coil 22, causing the lower end of the iron core 24 to repel the positioning magnet 25. The sliding sleeve 23 moves upward along the guide sleeve 21, simultaneously driving the iron core 24 and the coil 22 upward, making the upper end of the iron core 24 closer to the armature magnetic spring 3. The upper end of the iron core 24 repels the armature magnetic spring 3, making the armature magnetic spring 3 electrically connected to the second high-voltage output electrode 7. When no current flows through the coil 22, the armature magnetic spring 3 is located between the first high-voltage output electrode 6 and the second high-voltage output electrode 7. With the above structure, as Figure 7As shown, a vertical guide groove 231 is provided around the sliding sleeve 23. A ball bearing 232 is provided between the guide groove 231 and the guide sleeve 21. The ball bearing 232 reduces the resistance to movement of the sliding sleeve 23 relative to the guide sleeve 21. To prevent the sliding sleeve 23 from sliding out of the guide sleeve 21 under gravity, a limiting ring can be provided at the upper end of the guide sleeve 21, which limits the sliding sleeve 23 after it has moved upward a certain distance. It is understood that, as... Figure 6 As shown, the armature magnetic spring 3 includes a spring fixing plate 31, a lifting kinetic energy magnet 32, and an armature piece 33. The spring fixing plate 31 is fixed on the housing 1, one end of the armature piece 33 is fixed on the spring fixing plate 31, and the lifting kinetic energy magnet 32 ​​is fixed on the armature piece 33. Specifically, the magnet is fixed in the middle of the armature piece 33.

[0020] The working process of this utility model:

[0021] In the operation of this utility model relay, when the first high-voltage output electrode 6 contacts the armature magnetic spring 3, the circuit corresponding to the first high-voltage output electrode 6 is activated; when the second high-voltage output electrode 7 contacts the armature magnetic spring 3, the circuit corresponding to the second high-voltage output electrode 7 is activated. When the lifting electromagnet 2 pushes the armature magnetic spring 3 upward through magnetic repulsion to contact the second high-voltage output electrode 7, the lifting electromagnet 2 can automatically rise to maintain sufficient repulsion. During the rising process, the iron core 24 generates an electromagnetic field under the action of the coil 22, causing the lower end to attract the positioning magnet 25 of the iron core 24, and simultaneously attracting the armature magnetic spring 3 at the upper end. The armature magnetic spring 3 is electrically connected to the first high-voltage output electrode 6. When the armature magnetic spring 3 needs to be pushed upward to energize the coil 22, the iron core 24 generates an electromagnetic field under the action of the coil 22, causing the lower end to repel the positioning magnet 25 of the iron core 24. The sliding sleeve 23 moves upward along the guide sleeve 21, simultaneously driving the iron core 24 and the coil 22 to move upward, making the upper end of the iron core 24 closer to the armature magnetic spring 3. The upper end of the iron core 24 repels the armature magnetic spring 3, making the armature magnetic spring 3 electrically connected to the second high-voltage output electrode 7. When no current flows through the coil 22, the armature magnetic spring 3 is located between the first high-voltage output electrode 6 and the second high-voltage output electrode 7.

[0022] This utility model discloses a relay that, by connecting the lifting electromagnet 2 to the positive and negative terminals of the power supply in different ways, allows the lifting electromagnet 2 to generate an attractive or repulsive force on the armature magnetic spring 3, thereby controlling the conduction or disconnection of two sets of circuits. Simultaneously, to compensate for insufficient magnetic force due to distance, the lifting electromagnet 2 rises using repulsive force, ensuring that the armature magnetic spring 3 and the lifting electromagnet 2 maintain a close working distance. This helps reduce the number of relays used in the equipment, lowers installation difficulty and cost, and ensures reliable operation. In addition to controlling the working state of two sets of high-voltage circuits, this relay also has a fully disconnected mode, giving it three modes for more flexible application and strong adaptability.
