Potato machine control relay

Abstract

The invention discloses a potato machine control relay, which comprises a frame, a coil, an iron core, an armature, static contact plates and a contact pin, the iron core is fixed at the bottom in the frame, the coil is wound on the iron core, sliding rods are installed at the positions, on the two sides of the iron core, of the bottom in the frame, a sliding plate is arranged on the sliding rods in a sliding connection mode, and the sliding rods are sleeved with first springs, and the center of the sliding plate is provided with the armature. According to the invention, the iron core in the frame enables the armature to descend under the condition that the coil is electrified, so that a connecting plate is driven to slide in a sliding groove and a rack is driven to push a gear to rotate, and the second contact of a supporting rod in a second limiting groove is separated from and attached to the first contacts on the two sides under the rotation of a rotating column, the top parts of static contact plates on the two sides are provided with an insulating fixing plate, the bottom parts of the static contact plates are provided with stabilizing columns, the static contact plates penetrate through the stabilizing columns, and the two sides of the fixing plate are fixedly provided with second springs, thereby preventing the pressure drop of the relay contact caused by vibration, and enabling the contact to be more stable in contact.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a potato machine control relay. Background technique [0002] Control relay is an automatic electrical appliance, which is suitable for long-distance connection and disconnection of AC and DC small-capacity control circuits, and is used for control, protection and signal conversion in electric drive systems. The input of the control relay is usually electricity such as current and voltage, or it can be non-electricity such as temperature, pressure, speed, etc. The output is the electrical signal or the parameter change of the output circuit when the contact is activated. [0003] Relays are widely used in home appliances, such as automobiles, air conditioners, color TVs, refrigerators, washing machines, etc.; they are also used in industrial automation controls and instruments. Moreover, the traditional control relay on the potato machine often causes the contact pressure of the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the above-mentioned traditional control relay on the potato machine, the contact pressure of the relay is dropped due to vibration and collision, and it is easy to cause instant disconnection or jitter of the contact, which may cause structural damage in severe cases. The armature part of the problem can produce malfunction and affect the reliability of the relay, and the proposed potato machine control relay
