Description

Detachable relay pin

Technical Field

The utility model relates to the technical field of relays, in particular to a detachable relay pin.

Background

A relay is an electric control device that generates a predetermined step change in a controlled amount in an electric output circuit when a change in an input amount (excitation amount) meets a predetermined requirement. It has an interactive relationship between a control system (also called an input loop) and a controlled system (also called an output loop). It is commonly used in automated control circuits, which are actually a "recloser" that uses low current to control high current operation. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like.

The pin of relay is the important component of relay, and for automobile relay, its pin generally is by the simple substance metal or the composite metal preparation that the electric conductivity is good, and the pin in the use of relay in case damage will lead to whole relay to change, has caused the waste of resource, in addition, because general relay only depends on the pin to be associative with other circuits, the shake that appears in the automobile driving can make relay external shock, and then easily leads to pin and other circuit junction to take place to become flexible or pin self takes place slight deformation, and then probably takes place circuit fault.

To this end, we propose a removable relay pin.
