Description

Technical Field

[0001] The utility model relates to the field of electrical engineering technology, and more specifically to the technical field of an electromagnetically triggered circuit connection structure. The utility model is suitable for use in automated control systems, relays, sensor interfaces, and intelligent devices to achieve efficient and safe current control and signal transmission. Background Art

[0002] In the field of electrical engineering, electromagnetically triggered circuit connection structures are widely used in automated control systems and circuit switches. Existing electromagnetic triggering devices rely on continuous power to the electromagnetic coil to maintain a normally open state. This not only results in high energy consumption but also limits their long-term reliability. Prolonged operation can cause the electromagnetic coil to overheat, affecting the performance and lifespan of the switch.

[0003] Furthermore, frequent operation of conventional electromagnetic switches can place an additional burden on the circuit, affecting system stability. Consequently, a new electromagnetic trigger circuit connection structure is urgently needed to improve energy efficiency, reduce energy consumption, and enhance reliability over extended periods of operation to meet the sustained and stable performance requirements of modern automation equipment. Utility Model Content

[0004] This utility model aims to address the technical issues of high energy consumption and insufficient reliability of existing electromagnetic triggering devices during long-term operation. This utility model provides an electromagnetic trigger circuit connection structure. This structure combines the advantages of electromagnetic coils and permanent magnets to achieve efficient current control and signal transmission through the electromagnetic triggering mechanism.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] The utility model provides an electromagnetically triggered circuit connection structure, comprising an electromagnetic trigger unit and a permanent magnet unit; an electromagnet assembly is arranged in the electromagnetic trigger unit, the electromagnet assembly comprises a static iron core that can be magnetized by the permanent magnet unit, the permanent magnet unit is connected to an external circuit, and a magnetic permeability assembly is arranged in the permanent magnet unit and cooperates with the electromagnet assembly to realize the conduction or disconnection of the circuit in the permanent magnet unit.

[0007] Specifically, the combination of an electromagnetic trigger unit and a permanent magnet unit provides a circuit connection structure with rapid response and high trigger sensitivity, ensuring reliable circuit triggering. The circuit connection structure adopts a modular design for easy maintenance and replacement, and can adapt to different electrical parameters and operating environments to meet diverse market needs.

[0008] In this circuit connection structure, the electromagnet assembly only needs to be energized for a very short time to trigger the movement of the magnetic element. The circuit is then maintained in the on-state by the attraction between the electromagnet assembly and the magnetic permeability assembly, eliminating the need for the electromagnet assembly to operate continuously. To disconnect the circuit, a reverse current is applied to the electromagnet assembly to change the direction of the magnetic field, quickly releasing the attraction and triggering the reverse movement of the magnetic element. The magnetic field of another permanent magnet then maintains self-locking, achieving the circuit disconnection effect. This design significantly reduces energy consumption and improves system efficiency and reliability, making it particularly suitable for applications with frequent operations and long working hours.

[0009] The stationary core does not generate a magnetic field itself, but it can be magnetized by an external magnetic field, becoming a temporary magnet. When the magnetic field of a permanent magnet approaches the stationary core, the magnetic domains within the stationary core will rearrange, making the stationary core exhibit magnetism consistent with the external magnetic field, causing the stationary core to be attracted by the permanent magnet.

[0010] In one embodiment, the electromagnetic trigger unit further includes a trigger unit upper cover and a trigger unit bottom plate, and the electromagnet assembly further includes an electromagnetic coil and lead wires;

[0011] The trigger unit base plate and the trigger unit upper cover cooperate to form a closed cavity. The upper surface of the trigger unit base plate is provided with a mounting seat located inside the closed cavity. The static iron core is arranged in the mounting seat. The electromagnetic coil is wound on the outer wall of the mounting seat. The lead wires are divided into two, which are respectively connected to the two ends of the electromagnetic coil.

[0012] Specifically, the trigger unit base plate and the trigger unit cover together form a closed structure to ensure the stability of each component. The electromagnetic coil is fixed to the outer wall of the mounting base of the trigger unit base plate. The magnetic field generated after power is turned on can quickly interact with the permanent magnet unit to realize the triggering function of the circuit. The static iron core is located inside the electromagnetic coil to provide effective guidance for the magnetic field. At the same time, the lower structure of the trigger unit base plate is designed to seal the upper part of the permanent magnet unit casing to ensure the protection and airtightness of the internal components. The lead wire is connected to the electromagnetic coil to introduce current into the electromagnetic coil, thereby maintaining the normal operation of the electromagnetic trigger unit.

[0013] In one embodiment, the mounting seat is a columnar structure, a mounting groove for mounting the static iron core is provided at the bottom of the columnar structure, and the electromagnetic coil is wound on the outer wall of the columnar structure.

[0014] Specifically, the electromagnetic coil is fixed on the outer wall of the columnar structure of the trigger unit bottom plate, and the static iron core is fixed to the trigger unit bottom plate through the mounting groove reserved at the top of the columnar structure.

[0015] In one embodiment, a heat dissipation gap is provided between the inner wall of the upper cover of the trigger unit and the electromagnetic coil for dissipating heat from the electromagnetic coil.

[0016] Specifically, the trigger unit cover is used to cover and protect internal components and is designed with a heat dissipation gap to improve the heat dissipation performance of the electromagnetic coil.

[0017] In one embodiment, the permanent magnet unit includes a permanent magnet unit housing and a lower sealing plate. A vertical through-hole is provided inside the permanent magnet unit housing. The lower sealing plate is mounted on the bottom of the permanent magnet unit housing. A limiting boss is provided on the inner wall of the mounting hole. The limiting boss divides the mounting hole into an upper mounting hole and a lower mounting hole.

[0018] The magnetic permeability assembly includes a first shock-absorbing layer, a conductive terminal, a wire, a terminal block, a conductive layer, an insulating layer, a first magnetic element, and a second magnetic element;

[0019] The first shock-absorbing layer and the conductive terminal are integrated into one body in an up-down arrangement and fixedly mounted on the top of the upper mounting hole, and the two ends of the conductive terminal are connected to the external circuit via wires and terminal blocks respectively; the conductive layer, the insulating layer, and the first magnetic element are integrated into one body in an up-down arrangement and movably mounted in the upper mounting hole;

[0020] The second magnetic element is located at the bottom of the lower mounting hole and is fixed to the lower sealing plate;

[0021] The conductive terminal is in a disconnected state, and when the conductive layer contacts and cooperates with the conductive terminal, the circuit is conducted.

[0022] Specifically, wires are used to connect conductive terminals to wiring terminals. Wiring terminals are responsible for connecting wires in a circuit to an external circuit to achieve current transmission and control.

[0023] In one embodiment, the permanent magnet unit further includes a second shock-absorbing layer, which is fixedly arranged at the bottom of the upper mounting hole, and the sum of the thicknesses of the conductive layer, the insulating layer and the first magnetic element is less than the distance between the conductive terminal and the second shock-absorbing layer.

[0024] In one embodiment, the centers of the first magnetic element and the second magnetic element are located on the same straight line, and their magnetic directions are the same, so they attract each other.

[0025] In one embodiment, when the circuit needs to be turned on, the lead wire applies a positive current to the electromagnetic coil. The magnetic field generated by the electromagnetic coil is guided through the static iron core. The direction of the magnetic field is the same as the magnetic direction of the first magnetic element, and the first magnetic element is quickly brought close to the static iron core. Then, it achieves self-locking by its own magnetic force.

[0026] When the circuit needs to be non-conductive, the lead wire applies a reverse current to the electromagnetic coil. The magnetic field generated by the electromagnetic coil is guided by the static iron core. The direction of its magnetic field is opposite to the magnetic direction of the first magnetic element, forming a mutually repulsive relationship and pushing the first magnetic element to move rapidly toward the second magnetic element. Finally, under the magnetic force of the second magnetic element, self-locking is achieved.

[0027] In one embodiment, the first magnetic element and the second magnetic element are made of a material selected from the group consisting of magnet, neodymium iron boron, and ferrite.

[0028] Specifically, all magnetic components can be made of different magnetic materials as long as their functions are met, including but not limited to: magnets, neodymium iron boron and ferrite.

[0029] In one embodiment, the electromagnetic trigger unit and the permanent magnet unit cooperate to form a waterproof sealing structure.

[0030] Working principle:

[0031] When the circuit needs to be turned on, the electromagnetic coil in the electromagnetic trigger unit is energized to generate a magnetic field. This magnetic field is effectively guided by the static iron core, and its direction aligns with the magnetic direction of the first magnetic element, creating a mutual attraction. The attraction generated by the electromagnetic coil causes the first magnetic element to move toward the static iron core, bringing the conductive layer into contact with the conductive terminal, thus closing the circuit and turning it on.

[0032] After the circuit is turned on, the lead wire applies a signal to the electromagnetic coil to cut off the power to the electromagnetic coil. The attraction between the first magnetic element and the static iron core is still valid, and this attraction can keep the circuit closed.

[0033] When the circuit needs to be disconnected, the lead wire applies a reverse current to the electromagnetic coil in the electromagnetic trigger unit. The reverse magnetic field generated by the electromagnetic coil is opposite to the magnetic direction of the first magnetic element, repelling each other. Simultaneously, the second magnetic element's attraction rapidly moves away from the static iron core, separating the conductive layer from the conductive terminal, disconnecting the circuit and making it disconnected.

[0034] After the circuit is disconnected, the lead wire applies a signal to the electromagnetic coil, which cuts off the power to the electromagnetic coil. The first magnetic element and the second magnetic element have the same magnetic direction and attract each other to remain stationary.

[0035] The beneficial effects of the utility model are as follows:

[0036] 1. This utility model designs an electromagnetically triggered circuit connection structure that achieves efficient and rapid circuit connection and disconnection through the cooperation of an electromagnet and a permanent magnet. The circuit is quickly triggered by the transient magnetic field of the electromagnetic coil and the attractive interaction between it and the permanent magnet, thus avoiding the wear and delay caused by physical contact in traditional mechanical triggering methods. This design achieves a contactless connection response, significantly improving the circuit's reaction speed and system reliability. The structure is also fully dustproof and waterproof, effectively preventing electrical leakage while also reducing mechanical wear and extending service life.

[0037] 2. The traditional electromagnetic trigger device has a significant increase in energy consumption due to the continuous power supply of the electromagnetic coil during long-term operation. At the same time, the overall reliability and service life are reduced due to overheating and component aging.

[0038] 3. This structure combines the advantages of electromagnetic coils and permanent magnets, and achieves efficient current control and signal transmission through an electromagnetic trigger mechanism.

[0039] 4. The combination of the electromagnetic trigger unit and the permanent magnet unit significantly improves the circuit's triggering speed, enabling the circuit to be closed and opened in a very short time. Furthermore, the attractive force between the first magnetic element and the static iron core maintains the circuit's closed state even after power is removed, enhancing system stability and ensuring long-term operational reliability. This structural design ensures effective spacing between components, avoiding direct contact, which not only improves safety but also reduces the risk of overheating. This structure reduces the use of traditional mechanical components, simplifies the overall design, and improves the reliability and maintainability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] like Figures 1 to 6 As shown, this embodiment provides an electromagnetically triggered circuit connection structure, including an electromagnetic trigger unit 1 and a permanent magnet unit 2. The electromagnetic trigger unit 1 and the permanent magnet unit 2 form a waterproof sealing structure when combined. An electromagnet assembly is provided in the electromagnetic trigger unit 1, and the electromagnet assembly includes a static iron core 103 that can be magnetized by the permanent magnet unit 2. The permanent magnet unit 2 is connected to an external circuit. A magnetic permeability assembly is provided in the permanent magnet unit 2 and cooperates with the electromagnet assembly to realize the conduction or disconnection of the circuit in the permanent magnet unit 2.

[0056] Specifically, the combination of the electromagnetic trigger unit 1 and the permanent magnet unit 2 provides a circuit connection structure with rapid response and high trigger sensitivity, ensuring reliable circuit triggering. The circuit connection structure adopts a modular design, facilitating maintenance and replacement, and can adapt to different electrical parameters and operating environments, thus meeting diverse market needs.

[0057] In this circuit connection structure, the electromagnet assembly only needs to be energized for a very short time to trigger. The attractive force between the electromagnet and the magnetic permeability component then maintains the circuit on, eliminating the need for the electromagnet to operate continuously. To disconnect the circuit, a reverse current is applied to the electromagnet assembly, redirecting the magnetic field and quickly releasing the attractive force, effectively disconnecting the circuit. This design significantly reduces energy consumption and improves system efficiency and reliability, making it particularly suitable for applications with frequent operations and long operating times.

[0058] The stationary core does not generate a magnetic field itself, but it can be magnetized by an external magnetic field, becoming a temporary magnet. When the magnetic field of a permanent magnet approaches the stationary core, the magnetic domains within the stationary core will rearrange, making the stationary core exhibit magnetism consistent with the external magnetic field, causing the stationary core to be attracted by the permanent magnet.

The electromagnetic coil 102 is wound on the outer wall of the mounting seat. The lead wire 105 is divided into two, which are respectively connected to the two ends of the electromagnetic coil 102.

[0063] Specifically, the trigger unit base plate 104 and the trigger unit upper cover 101 together form a closed structure to ensure the stability of each component. The electromagnetic coil 102 is fixed on the outer wall of the mounting base of the trigger unit base plate 104. The magnetic field generated after power is turned on can quickly interact with the permanent magnet unit 2 to realize the triggering function of the circuit. The static iron core 103 is located inside the electromagnetic coil 102 to provide effective guidance for the magnetic field.

[0079] Specifically, the wire 203 is used to connect the conductive terminal 202 to the wiring terminal 204. The wiring terminal 204 is responsible for connecting the wire 203 in the circuit to the external circuit to achieve current transmission and control.

[0080] Example 6

[0081] This embodiment is a further optimization based on the embodiment 5, specifically:

[0082] The permanent magnet unit 2 also includes a second shock-absorbing layer 207 , which is fixedly arranged at the bottom of the upper mounting hole. The sum of the thicknesses of the conductive layer 205 , the insulating layer 206 and the first magnetic element 4 is less than the distance between the conductive terminal 202 and the second shock-absorbing layer 207 .

[0083] The centers of the first magnetic element 4 and the second magnetic element 5 are located on the same straight line, and their magnetic directions are the same, so they attract each other.

[0084] When the circuit needs to be turned on, the lead wire 105 applies a positive current to the electromagnetic coil 102. The magnetic field generated by the electromagnetic coil 102 is guided by the static iron core 103. The direction of the magnetic field is the same as the magnetic direction of the first magnetic element 4, forming a mutual attraction relationship.

[0085] When the circuit needs to be non-conductive, the lead wire 105 applies a reverse current to the electromagnetic coil 102. The magnetic field generated by the electromagnetic coil 102 is guided by the static iron core 103. The direction of the magnetic field is opposite to the magnetic direction of the first magnetic element 4, forming a mutually repelling relationship.

[0086] The first magnetic element 4 and the second magnetic element 5 are made of a material selected from the group consisting of magnet, neodymium iron boron and ferrite.

[0087] Specifically, all magnetic components can be made of different magnetic materials as long as their functions are met, including but not limited to: magnets, neodymium iron boron and ferrite.

[0088] Working principle:

[0089] When the circuit needs to be turned on, the electromagnetic coil 102 in the electromagnetic trigger unit 1 is energized to generate a magnetic field. This magnetic field is effectively guided by the static iron core 103, and its direction aligns with the magnetic direction of the first magnetic element 4, creating a mutual attraction. Under the attraction generated by the electromagnetic coil 102, the first magnetic element 4 approaches the static iron core 103, bringing the conductive layer 205 into contact with the conductive terminal 202, thereby closing the circuit and turning it on.

[0090] After the circuit is turned on, the lead wire 105 applies a signal to the electromagnetic coil 102 to cut off the power to the electromagnetic coil 102 , and the attraction between the first magnetic element 4 and the static iron core 103 is still valid, and this attraction can keep the circuit closed.

[0091] When the circuit needs to be disconnected, the lead wire applies a reverse current to the electromagnetic coil 102 in the electromagnetic trigger unit 1. At this time, the reverse magnetic field generated by the electromagnetic coil 102 is opposite to the magnetic direction of the first magnetic element 4, repelling each other. At the same time, under the attraction of the second magnetic element 5, the electromagnetic coil 102 quickly moves away from the static iron core 103, thereby separating the conductive layer 205 from the conductive terminal 202, disconnecting the circuit and making it disconnected.

[0092] After the circuit is disconnected, the lead wire 105 applies a signal to the electromagnetic coil 102, so that the electromagnetic coil 102 is de-energized. The first magnetic element 4 and the second magnetic element 5 have the same magnetic direction, attract each other and remain stationary.

[0093] Additionally, the electromagnetic coil's current can be adjusted based on actual usage to meet varying operational requirements. The size can be increased or decreased depending on the application scenario and manufacturing process. The electromagnetic trigger unit can optionally eliminate the use of a static iron core and instead employ two sets of permanent magnet units positioned one above the other to achieve the same effect as a static iron core. Conductive terminals and wires can be arranged in multiple groups to meet diverse circuit connection requirements. The electromagnetic trigger unit and multiple sets of permanent magnet units can be combined to achieve flexible circuit control.
