Wire comb overlying spark gap
View Patent ↗An approach is provided for mounting individual wires from multi-wire cables onto circuit boards. A wire comb is mounted adjacent one or more ends of the circuit board to permit a way to space apart individual wires, to hold them in place; and to permit welding or soldering of the wires to the appropriate connections or the circuit board during an overmolding process.
1. A circuit board assembly comprising a board having upper and lower surfaces, opposing ends and side edges, at least one wire comb mounted on said upper surface and adjacent one end thereof, wherein at least one wire comb includes
a base,
at least one mounting pin extending outwardly from said base, and
at least one wire mount area defined by a shaped opening that receives and holds a portion of wire, wherein the base overlies said circuit board and a plurality of spark gaps formed in the surface of said circuit board.
2. A method of manufacturing a cable system having an electronic circuit therein, the circuit being on a circuit board, the method comprising:
attaching at least one wire comb to the circuit board;
mounting the wire comb in a flush manner relative to the circuit board so that the wire comb overlies at least one spark gap formed in the circuit board thereby providing a seal over the at least one spark gap;
inserting at least one wire into said at least one comb, and
electrically connecting said at least one wire to said circuit board; and
forming an over mold of said circuit board.
3. A circuit board assembly comprising a board having upper and lower surfaces, opposing ends and side edges, at least one wire comb mounted on said upper surface and adjacent one end thereof, a plurality of spark gaps formed in the circuit board adjacent at least one of the opposing ends and wherein the wire comb overlies said plurality of spark gaps wherein at least one wire comb includes
a base,
at least one mounting pin extending outwardly from said base, and
at least one wire mount area defined by a shaped opening that receives and holds a portion of wire.
4. The circuit board assembly of claim 3 , wherein the at least one wire comb forms a chamber between the base and the circuit board at each of the plurality of spark gaps.
5. The circuit board assembly of claim 3 , further including a plurality of wire combs mounted at spaced apart locations around side edges of the circuit board.
6. A method of manufacturing a cable system having an electronic circuit therein, the circuit being on a circuit board wherein the circuit board includes a plurality of spark gaps adjacent at least one end thereof, the method comprising:
attaching at least one wire comb to the circuit board thereby providing a seal between the wire comb and the circuit board thereby protecting the spark gaps;
inserting at least one wire into said at least one comb, and
electrically connecting said at least one wire to said circuit board; and
forming an over mold of said circuit board.
7. The method as in claim 2 , wherein the step of forming of an over mold includes the steps of:
forming a first over mold from a first molding material covering the circuit board and the at least one wire comb, and
forming a second over mold from a second molding material covering at least the first over mold material.
8. The method of manufacturing as in claim 7 , wherein the first and second molding materials comprise the same material.
9. The method of manufacturing as in claim 7 , wherein the first and second molding materials comprise different materials.
10. The method as in claim 6 , wherein the step of forming of an over mold includes the steps of:
forming a first over mold from a first molding material covering the circuit board and the at least one wire comb, and
forming a second over mold from a second molding material covering at least the first over mold material.
11. The method of manufacturing as in claim 10 , wherein the first and second molding materials comprise the same material.
12. The method of manufacturing as in claim 10 , wherein the first and second molding materials comprise different materials.
