Abstract
Relay connectors are arranged to supply power from power boards arranged on the back side of a chassis having a substantially plate-shaped configuration to discharge tubes arranged on the front side of the chassis. Each relay connector includes a holder having an insulation property and to be mounted to the chassis, and further includes a relay terminal mounted to the holder and capable of electrical connection to the discharge tube and the power board. The relay terminal is immune to direct contact with the chassis. This enables the use of a metallic chassis.
Claims22
A relay connector to be arranged to supply power from a power source arranged on a back side of a chassis having substantially a plate-like shape to a discharge tube arranged on a front side of said chassis, said relay connector comprising:
- a holder having an insulation property and to be mounted to said chassis;
- and
- a relay terminal mounted to said holder and capable of electrical connection to said discharge tube and said power source, wherein:
- said power source includes an on-board connector mounted on a back surface of a circuit board that is to be arranged parallel to said chassis so that the back surface is on an opposite side of said chassis, and further includes an output terminal arranged in an engaging recess that is formed on said on-board connector so as to correspond to a fitting hole formed through said circuit board;
- a wall portion, capable of projecting to the back side of said chassis and penetrating through said fitting hole so as to be inserted into said engaging recess, is provided on said holder;
- and
- a board connecting portion capable of connection to said output terminal is provided on said relay terminal so as to extend along said wall portion.
Amounting structure of a relay connector and a power source, said relay connector being arranged to supply power from said power source arranged on a back side of a chassis having substantially a plate-like shape to a discharge tube arranged on a front side of said chassis;
- said mounting structure, wherein:
- said power source includes an on-board connector mounted on a back surface of a circuit board that is to be arranged parallel to said chassis so that the back surface is on an opposite side of said chassis, and further includes an output terminal arranged in an engaging recess that is formed on said on-board connector so as to correspond to a fitting hole formed through said circuit board;
- said relay connector includes a holder having an insulation property and to be mounted to said chassis, and further includes a relay terminal mounted to said holder and capable of electrical connection to said discharge tube and said power source;
- a wall portion, capable of projecting to the back side of said chassis and penetrating through said fitting hole so as to be inserted into said engaging recess, is provided on said holder;
- and
- a board connecting portion capable of connection to said output terminal is provided on said relay terminal, so as to extend along said wall portion.
A mounting structure of a discharge tube and a power source on a relay connector, used to mount said discharge tube and said power source to said relay connector that is arranged to supply power from said power source arranged on a back side of a chassis having substantially a plate-like shape to said discharge tube arranged on a front side of said chassis;
- said mounting structure, wherein:
- said relay connector includes a holder having an insulation property and to be mounted to said chassis, and further includes a relay terminal mounted to said holder and capable of electrical connection to said discharge tube and said power source;
- and
- a tube engaging portion arranged to allow said discharge tube to enter therein after approaching along a direction substantially perpendicular to a surface of said chassis, and a power engaging portion arranged to allow an on-board connector of said power source to engage therewith after approaching along a direction substantially perpendicular to the surface of said chassis are provided on said holder.
A lighting device for a display device comprising:
- a chassis having substantially a plate-like shape;
- a discharge tube arranged on a front side of said chassis;
- a power source arranged on a back side of said chassis;
- and
- a relay connector to supply power from said power source, said relay connector including a holder having an insulation property and to be mounted to said chassis and a relay terminal mounted to said holder and capable of electrical connection to said discharge tube and said power source, wherein:
- said power source includes an on-board connector mounted on a back surface of a circuit board that is to be arranged parallel to said chassis so that the back surface is on an opposite side of said chassis, and further includes an output terminal arranged in an engaging recess that is formed on said on-board connector so as to correspond to a fitting hole formed through said circuit board;
- a wall portion, capable of projecting to the back side of said chassis and penetrating through said fitting hole so as to be inserted into said engaging recess, is provided on said holder;
- and
- a board connecting portion capable of connection to said output terminal is provided on said relay terminal so as to extend along said wall portion.
