Abstract

Abstract A core securing clip to hold the two core members of the core of a surface mount magnetic component together is designed with a large planar surface to provide a suitable surface to facilitate the use of pick and place apparatus in mounting the magnetic component on a printed circuit board. The subject clip is fastened over the top of the magnetic component and has spring loaded members that apply forces to opposing sides of the two core members joined together in order to join them together as a single core.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 207 words
In combination: a circuit substrate; a magnetic component mounted on the circuit substrate; the magnetic component comprising, a magnetic core having a first and second core member; a spring clip formed out of a resilient metal and mounted for securing the first and second core members together; the spring clip comprising: a flat planar surface substantially covering a top area of the magnetic component; first and second pairs of pressure bearing members, positioned on opposing sides of the flat planar surface, each pressure bearing member having a substantially oblique V-shaped bend at its core engaging end with each pressure bearing member engaging a side of one of the first and second core members with spring produced pressure of the resilient metal in which a free end of each oblique V-shaped bend engages a side of the core member and is operative for securing the first and second core members together; and first and second securing members positioned on opposite sides between the opposing sides of the planar surface; said securing members having a sufficiently longitudinal member dimension extending downwardly therefrom with a substantially oblique V-shaped bend at the end so that a free end of each oblique V-shaped bend engages an underside of the mangetic core component.
Claim 2
Dependent Claim 207 words
In combination: a circuit substrate; a magnetic component mounted on the circuit substrate; the magnetic component comprising, a magnetic core having a first and second core member; a spring clip formed out of a resilient metal and mounted for securing the first and second core members together; the spring clip comprising: a flat planar surface substantially covering a top area of the magnetic component; first and second pairs of pressure bearing members, positioned on opposing sides of the flat planar surface, each pressure bearing member having a substantially oblique V-shaped bend at its core engaging end with each pressure bearing member engaging a side of one of the first and second core members with spring produced pressure of the resilient metal in which a free end of each oblique V-shaped bend engages a side of the core member and is operative for securing the first and second core members together; and first and second securing members positioned on opposite sides between the opposing sides of the planar surface; said securing members having a sufficiently longitudinal member dimension extending downwardly therefrom with a substantially oblique V-shaped bend at the end so that a free end of each oblique V-shaped bend engages an underside of the mangetic core component.
Claim 3
Dependent Claim 185 words
A circuit arrangement, comprising: a magnetic component, including; a core having first and second core members, clip apparatus formed from resilient metal for securing the first and second core members into one core, the clip apparatus having a planar surface substantially covering a top of the magnetic component for facilitating handling of the magnetic component by pick and place apparatus; the clip apparatus including first and second pairs of pressure bearing members, positioned on opposing sides of the flat planar surface, each pressure bearing member having a V-shaped bend at its engaging end with the free end of the V-shaped each individually engaging a side of one of the first and second core members with spring induced pressure of the resilient metal and operative for securing the first and second core members together; the clip apparatus including first and second securing members having a linear dimension of sufficient length positioned on opposing sides of the planar surface and extending downwardly therefrom, and including a V-shaped bend at the free end of each member so that the free end engages an underside of the magnetic core.
Claim 4
Dependent Claim 185 words
A circuit arrangement, comprising: a magnetic component, including; a core having first and second core members, clip apparatus formed from resilient metal for securing the first and second core members into one core, the clip apparatus having a planar surface substantially covering a top of the magnetic component for facilitating handling of the magnetic component by pick and place apparatus; the clip apparatus including first and second pairs of pressure bearing members, positioned on opposing sides of the flat planar surface, each pressure bearing member having a V-shaped bend at its engaging end with the free end of the V-shaped each individually engaging a side of one of the first and second core members with spring induced pressure of the resilient metal and operative for securing the first and second core members together; the clip apparatus including first and second securing members having a linear dimension of sufficient length positioned on opposing sides of the planar surface and extending downwardly therefrom, and including a V-shaped bend at the free end of each member so that the free end engages an underside of the magnetic core.
Claim 5
Dependent Claim 33 words
A combination as claimed in claim 1; wherein the flat planar surface includes first and second stiffness enhancement ribs formed into the planar surface and aligned with a grain of the resilient metal.
Claim 6
Dependent Claim 20 words
A circuit arrangement as claimed in claim 2; wherein the planar surface includes stiffness enhancement ribs into the planar surface.
