Description

TECHNICAL FIELD

[0001] The present application relates to the field of relay processing, in particular to a spring leaf pressing buckle device for relay assembly. BACKGROUND

[0002] A relay is an electric control device, which is a kind of electric appliance that makes the controlled quantity in the electrical output circuit have a predetermined step change when the input quantity (excitation quantity) changes to a specified requirement. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). It is usually applied to the control circuit of automation. It is actually a kind of "automatic switch" that uses small current to control large current operation. Therefore, it plays the role of automatic adjustment, safety protection, and conversion of circuit in the circuit. The relay is mainly composed of a coil, a spring leaf, an iron core, a magnetic yoke, a spring, an adjusting nut, an armature, etc. During production, the spring leaf is pressed and fixed on the relay.

[0003] At present, the spring leaf pressing buckle device for relay assembly cannot detect the pressing force when pressing the buckle. When the pressure is too large, the spring leaf is easily deformed. When the pressure is too small, it is difficult to tightly press. If the pressing force is not controlled well, it will affect the overall quality of the relay. Moreover, it cannot accurately detect whether the pressure plate is accurately aligned with the spring leaf, which is not conducive to observing the accuracy of the pressing. In addition, it cannot quickly replace different shaped pressure plates according to the needs, which makes its adaptability and adjustability poor, and is not conducive to completing high-precision assembly.
