Claims (13)
1. A coil form adapted to be counted in an opening defined by a printed circuit board or the like, said coll form comprising a tubular body of electrically insulating material having one end formed to mate with the opening and the tubular axis of said coil form extending outwardly generally perpendicular to the plane of the printed circuit board positioning means affixed to said body and extending outwardly from the outer surface thereof for rotationally positioning said body relative to the printed circuit board, and solderable means affixed to the outer surface of said body adjacent the one end for engaging conducting portions of the printed circuit board to mechanically mount the coil form.
2. A coll form according to claim 1, vhereln the solderable means includes a sleeve of conducting material at least partially encircling the body at one end.
3. A coil form according to claim 1 or 2, wherein the tubular body is molded from plastic.
4. A coll form according to claim 1, 2 or 3, wherein the positioning means includes an integrally formed collar.
5. · A coll form according to any one of claims 1 to 4, wherein the positioning means includes an axially extending ridge for orienting the rotational position of the body relative to the printed circuit board.
6. A coil form according to any one of claims 1 to S, including axially extending ridges affixed to the inner surface of the body in radially inwardly extending relationship, said ridges being formed of material which will form threads upon the insertion of an externally threaded, cylindrical core
7. A coil form according to any of claims 1 to 6, adapted to have an antenna coll wound therein, said coil form including an antenna contact affixed to the end opposite the one end.
8. , A coil form according to claim 7, wherein the antenna contact includes electrically conducting resilient material affixed to the opposite end of the body for electrical contact with the antenna coil and extending generally axially outward from the body for resilient electrical contact with an antenna.
9. » A tunable antenna coil for use in a radio incorporating a printed circuit board and having an antenna, said coil including, a tubular molded plastic body having one end thereof engaged in an opening defined within the printed circuit board, a sleeve formed of solderable material affixed to the outer surface of said body in coaxial alignment adjacent the one end thereof and soldered to conductors on the printed circuit board for mechanical and electrical contact therewith, an integral-ly formed, outwardly extending collar in the outer periphery of said body adjacent the one end, said collar butting against the printed circuit board adjacent the opening therethrough for positioning said body relative to the printed circuit board, integrally formed, longitudinally oriented, radially inwardly extending ribs in the inner periphery of said body threadedly engaged with a cylindrical externally threaded core, resilient" antenna contact means affixed to said body adjacent the end opposite the one end and extending generally axially outwardly therefrom into and adapted for electrical contact with the V 42657/2 antenna, and coll means wrapped around said body and electrically contacting said sleeve and said antenna contact
10. A method of mechanically mounting a coil form to a printed circuit board comprising the steps of providing a tubular coil form haying a solderable means affixed to one end thereof in at least partially encircling engagement, inserting the one end of the coil form in a mating opening defined by the printed circuit board with the tubular axis of said coil form extending outwardl generally perpendicular to the plane of the printed circuit board, said printed circuit board having conductors overlapping at least a portion of the periphery of the opening, and wave soldering the solderable means of the coil form to the conductors of the printed circuit board.
11. A coil form for a printed circuit board or the like constructed substantially as herein described with reference to the accompanying drawings.
12. A tunable antenna coil constructed substantially as herein described with reference to the accompanying drawings.
13. A method of mechanically mounting a coil form to a printed circuit board substantially as herein described. . SCsGB
