Method and apparatus for destructible trap/filter

A method for disconnecting a connecting pin in an electrical filter, the filter including a first filter section having a first set of electrical filter components, with the first set of electrical filter components including a plurality of first primary tunable coils arranged parallel to each other, and a second filter section having a second set of electrical filter components, with the second set of electrical filter components including a plurality of second primary tunable coils arranged parallel to each other, the method comprising the steps of:

• providing an electrical isolation shield disposed between the first and second filter sections for electrically isolating the first and second filter sections from one another, wherein the electrical isolation shield includes a first plate and a second plate which are rotatable with respect to each other, wherein the first plate includes a first cutout portion and the second plate includes a second cutout portion;
• locking the first plate to the first filter section;
• locking the second plate to the second filter section;
• and
• disposing the first and second plates such that when the electrical filter is screwed into a connecting device, the first filter section is limited in its rotation with respect to the second filter section such that an opening formed by the first and second cutout portions permits the connecting pin to electrically connect the first filter section with the second filter section, and when the electrical filter is unscrewed from the connecting device, the first filter section rotates with respect to the second filter section such that the connecting pin breaks electrical connection between the first filter section and the second filter section.

A method of breaking an electrical connection between first and second filter sections of an electrical filter contained within a housing, wherein the first filter section includes a first filter circuit and the second filter section includes a second filter circuit, comprising the steps of:

• making the first filter section rotatable with respect to the housing;
• locking the second filter section to the housing;
• and
• electrically connecting the first filter circuit to the second filter circuit, such that upon rotating the electrical filter in a first direction into a connecting device, the first and second filter sections are in a locked position, and upon rotating the electrical filter in a second direction from the connecting device, the second filter section rotates with respect to the first filter section, thereby breaking the electrical connection.
