Securement for transformer core utilized in a transformer power supply module and method to assemble same

A method for releasably securing a transformer power supply assembly together which includes a stacked arrangement of a first transformer core plate positioned to overlie a circuit board, a second transformer core plate positioned to underlie the first transformer core plate and the circuit board, and a carrier member positioned beneath the second transformer core plate, the first and second transformer core plates contact one another through at least one opening positioned in the circuit board, including the steps of:

• aligning a releasable securement apparatus with the stacked arrangement including positioning a span member of the apparatus to overlie the first transformer core plate and positioning each of at least two engagement leg members connected to opposing sides of the span member and which are in converging alignment with one another and in which a hook member is secured to each of the leg members in which the distance between the hook members is shorter than the distance between opposing sides of the stacked arrangement;
• applying a force to the span member flexing the span member and increasing the distance between the hook members providing clearance of the hook members along the opposing sides of the stacked arrangement;
• moving the engagement leg members along opposing sides of the stacked arrangement with at least one foot member secured to at least one cross member which is secured transverse to the span member and in which the at least one foot member is interposed between the span member and the surface of the top core plate member until the at least one foot member is positioned resting on the top core plate and the hook members are positioned short of an engagement position of the carrier;
• and
• applying another force to the span member flexing the cross member relative to the span member moving the leg engagement members further along the opposing sides of the stacked arrangement until the hook members reach the engagement position of the carrier;
• and
• releasing the application of the other force to the span member with the hook members engaging the engagement position of the carrier member maintaining the cross member in a flexed position biasing the at least one foot member against the top core plate and the second core plate with at least one of the leg engagement members biased against at least one of the opposing sides of the stacked arrangement.
