Problems solved by technology

[0003] When the current electromagnetic relay is energized and used, because the electromagnet is energized to generate electromagnetic force, the armature is attracted. At the moment when the armature is attracted, the contact copper sheet at the high-voltage part is collided. If things go on like this, the contact copper at the high-voltage part will be damaged. The chip is collided and deformed, which makes the power supply of the high-voltage line unstable and affects the stability of the electromagnetic relay's performance; and the current electromagnetic relay's applicable voltage range is limited, and it is impossible to manually adjust the applicable voltage of the electromagnetic relay according to the actual use , As a result, electrical appliances with different voltages can only use corresponding electromagnetic relays, which greatly reduces the scope of application of the electromagnetic relay; at the same time, when the internal components of the current electromagnetic relay are short-circuited, it is often impossible to protect the electrical appliances controlled by the electromagnetic relay immediately. It is easy to cause the internal circuit of the electrical appliance to burn out due to a short circuit, which reduces the safety of the electromagnetic relay.

Embodiment 1

[0033] Example 1, such as Figure 2-5 As shown, when the low-voltage line is energized, the electromagnet 14 will generate magnetic force, attracting the armature 15 to rotate downward with its hinge point as the axis, because the magnetic force generated by the electromagnet 14 is completed instantaneously, forcing the armature 15 to rotate at an extremely fast speed. Turning downward, the first spring 10 is stretched under force during the process, and the moving speed of the armature 15 is initially buffered, and after the bottom of the armature 15 is in contact with the roller 164, the third spring 161 will also be shortened under force, and the force on the armature 15 will be shortened. 15 to carry out secondary buffering to avoid the conductive plate 12 from colliding with the second contact copper sheet 13 at an extremely fast speed, causing the conductive plate 12 and the second contact copper sheet 13 to deform due to collision, and when the electromagnet 14 is not en...

Embodiment 2

[0034] Example 2, such as Figure 1-7 As shown, when the electromagnetic relay needs to be used in a high-voltage circuit, it can be adjusted according to the actual voltage in advance. First, unscrew the bolt 2, remove the door 5 from the outside of the main body 1, and then manually turn the second gear 704 rotates, the second gear 704 and the first gear 708 are used to drive the rotating shaft 707 to rotate, forcing the components connected to the outside of the rotating shaft 707 to rotate together until the fuse 706 of appropriate resistance moves between the two sets of first contact copper sheets 8, and the corresponding The protrusion on the fixing seat 705 is also snapped into the groove on the top of the first contact copper sheet 8. In the process, after the fixing seat 705 is initially in contact with the first contact copper sheet 8, the two sets of fixing seats 705 will gradually approach each other. For a short distance, the movable rings 709 will be closer to e...

Abstract

The invention discloses an electromagnetic relay with stable performance. The relay comprises a main bin, a bin door is arranged on one side of the main bin, bolts are symmetrically installed at the four corners of the outer side of the bin door in a threaded mode, an electromagnet is installed at one end of the bottom in the main bin, and an installation bin is arranged at the other end of the top in the main bin. A side plate is mounted at the end, close to the electromagnet, of the installation bin, and a buffer assembly is arranged in the middle of the top of the side plate. Through cooperative use of the main body bin, the side plate, the first spring, a first insulating rod, a conductive plate, a second contact copper sheet, the electromagnet, an armature and the buffer assembly, conditions that the conductive plate rapidly collides with the surface of the second contact copper sheet, the conductive plate and the second contact copper sheet deform due to collision, and the contact stability of the conductive plate and the second contact copper sheet is affected are avoided so that performance stability of the electromagnetic relay in a long-time use process is also ensured.

Description

technical field [0001] The invention relates to the technical field of electromagnetic relays, in particular to an electromagnetic relay with stable performance. Background technique [0002] Electromagnetic relay is an electronic control device, which has a control system (also known as input circuit) and a controlled system (also known as output circuit), usually used in automatic control circuits, it actually uses a smaller current, lower It is an "automatic switch" that controls a larger current and a higher voltage, so it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] When the current electromagnetic relay is energized and used, because the electromagnet is energized to generate electromagnetic force, the armature is attracted. At the moment when the armature is attracted, the contact copper sheet at the high-voltage part is collided. If things go on like this, the contact copper at the high-voltage part will b...
