Relay adjustment structure and methods

摘要

There is provided structure and methods for use in adjusting certain design parameters of a relay (10) during initial assembly of the relay (10). The structure includes an adjustment member (34) insertable between a bobbin (22) and a core (24). The adjustment member (34) is preferably U-shaped having arms (38,40) straddling the core (24) and a backspan (36) which acts as a stop to define the travel of an armature (26). A method of initially adjusting the relay (10) includes inserting the adjustment member (34) between the bobbin (22) and the core (24) and moving the armature (26) into engagement with the backspan (36). The adjustment member (34) is driven between the bobbin (22) and core (24) and permanently fixed in place when the desired parameters have been attained. An alternative method includes providing a relay having a motor assembly, including a bobbin and core, which may be moved about a pivot point in the relay. The armature is forced against the motor assembly until the desired design parameters are obtained and the motor assembly is then permanently fixed in place within the relay. A further alternative method includes providing a relay having a bobbin fixed with respect to the relay and a core movable within a bore of the bobbin. An armature is forced against the core moving it within the bore of the bobbin until the desired parameters have been obtained. Thereafter, the core is permanently fixed in position within the bore of the bobbin.
