Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a special relay for elevators. Background Art

[0002] A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirement, it causes the controlled quantity to undergo a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0003] Currently, when relays are used to control electrical circuits in elevators, since there are many operating lines in the elevator, multiple relays are required to work in combination. However, the relays on the elevator are installed in different positions, which makes it inconvenient to find which specific relay has a fault during subsequent maintenance. At the same time, the electrical connections of the relays are installed in a rigidly fixed manner, and the vibrations generated during the operation of the elevator can easily cause damage to the relays.
