Abstract
Abstract An electrical coil has a coil body with at least one end flange with wire guidance slots. Shell core halves are slipped onto the coil body and have guidance slots. A terminal carrier is provided for printed circuit boards having solder connections and onto which the coil is placed. Ends of a winding on the coil body are soldered to the solder terminals. The end flange of the coil body is fashioned as an end plate which carries solder terminals and has passages for the sidewalls and for a center bleb or projection of the one shell core half. The terminal carrier is replaced by an adapter plate that can be plugged onto the end plate. This adapter plate has solder terminals arranged in a prescribed grid dimension on its printed circuit board side, the ends of these solder terminals which face away therefrom being soldered to the solder terminals of the end plate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
187 words
An electrical coil, comprising: a coil body with at least one end flange having at least one wire guidance slot; two shell core halves around said coil body and each having at least one wire guidance slot; said at least one end flange of said coil body being an end plate carrying solder terminal elements arranged in a given pattern and having passage means for receiving side walls and a center projection of a lower one of the two shell core halves, wire winding ends of the coil being soldered to the solder terminal elements; and an adapter plate receiving said end plate, said adapter plate also having solder terminal elements whose first ends project from and are arranged at a printed circuit board side of the adapter plate in a desired pattern different than said given pattern, and opposite second ends of said adapter plate solder terminal elements being freely bent such that they are guided out of said adapter plate to a position directly adjacent to, abutting with, and electrically connected by solder to respective ones of the solder terminal elements of said end plate.
Claim 2
Dependent Claim
187 words
An electrical coil, comprising: a coil body with at least one end flange having at least one wire guidance slot; two shell core halves around said coil body and each having at least one wire guidance slot; said at least one end flange of said coil body being an end plate carrying solder terminal elements arranged in a given pattern and having passage means for receiving side walls and a center projection of a lower one of the two shell core halves, wire winding ends of the coil being soldered to the solder terminal elements; and an adapter plate receiving said end plate, said adapter plate also having solder terminal elements whose first ends project from and are arranged at a printed circuit board side of the adapter plate in a desired pattern different than said given pattern, and opposite second ends of said adapter plate solder terminal elements being freely bent such that they are guided out of said adapter plate to a position directly adjacent to, abutting with, and electrically connected by solder to respective ones of the solder terminal elements of said end plate.
Claim 3
Dependent Claim
68 words
An electrical coil according to claim 1 wherein the solder terminal elements of said end plate and said adapter plate comprise terminal pins, second ends of said terminal pins of said adapter plate facing away from the printed circuit board being arranged adjacent said terminal pins of said end plate, and opposite first ends of said terminal pins of said adapter plate being arranged in said desired pattern.
Claim 4
Dependent Claim
172 words
An electrical coil body, comprising: a coil body with an end flange; a shell around said coil body for enclosing the same; a coil body end flange comprising an end plate having solder terminal pins projecting away from the coil body, and wire ends of a coil wound on the coil body being soldered to the terminal pins in the end plate, said terminal pins of said end plate being arranged in a given location pattern; an adapter plate mounted to said end plate and having terminal pins having first end means extending from a mounting side of said adapter plate for soldering or plugging to or in a printed circuit board, said first end means being arranged in a desired pattern different than said given pattern, and at least some of said terminal pins being freely bent such that second ends thereof are guided out from the adapter plate into abutting contact with the terminal pins of said coil body end flange where they are electrically connected to the terminal pins.
Claim 5
Dependent Claim
172 words
An electrical coil body, comprising: a coil body with an end flange; a shell around said coil body for enclosing the same; a coil body end flange comprising an end plate having solder terminal pins projecting away from the coil body, and wire ends of a coil wound on the coil body being soldered to the terminal pins in the end plate, said terminal pins of said end plate being arranged in a given location pattern; an adapter plate mounted to said end plate and having terminal pins having first end means extending from a mounting side of said adapter plate for soldering or plugging to or in a printed circuit board, said first end means being arranged in a desired pattern different than said given pattern, and at least some of said terminal pins being freely bent such that second ends thereof are guided out from the adapter plate into abutting contact with the terminal pins of said coil body end flange where they are electrically connected to the terminal pins.
Claim 6
Dependent Claim
46 words
An electrical coil body according to claim 3 wherein said shell around said coil body comprises two shell core halves and wherein said end flange of said coil body has passage means for receiving side walls of a lower one of the two shell core halves.
Claim 7
Dependent Claim
31 words
An electrical coil body according to claim 3 wherein the second ends of the adapter plate terminal pins are electrically connected to the coil body end flange terminal pins by solder.
