摘要:
In a backlight module, when relay connectors exposed to a back side of a chassis are engaged with the connector portions of a lighting jig, the power from the power supply source of the lighting jig is supplied to discharge tubes via the connector portions and the relay connectors. Thereby, the discharge tubes can be lighted, even if a power board is not connected to the relay connectors. At the time, the lighting jig is arranged to face the back surface of the chassis, and therefore optical sheets can be mounted to the chassis from the front side.

A ferrule includes a body having a cylindrical shape. Elastic gripping portions are arranged on the body so as to bulge radially inwardly. The elastic gripping portions can have elastic contact with the outer circumferential surface of a glass tube. The body of the ferrule is mounted to the glass tube via the elastic gripping portions capable of elastic and radial deformation. Thereby, the variations in outer diameter of the glass tube can be absorbed, and therefore the dimensional control with high precision is not required for glass tubes at the time of manufacturing. This leads to cost reduction.

In a discharge tube, a conductive ferrule is provided on an end portion of a glass tube. The ferrule includes a body that is to be mounted to the outer circumference of the glass tube and has a contact portion to be electrically conductively fixed to a relay connector (or a bearing device). Further included is a conductive portion that extends from the body so as to have elastic contact with an outer lead. The outer lead will not be under load due to the weight of the discharge tube, but the conductive portion solely has elastic contact therewith. Thus, stress concentration on the outer lead can be prevented.

Discharge tubes, each of which includes a glass tube and a ferrule that has a substantially cylindrical shape and is fitted to each end portion of the glass tube, are supported by a plurality of pairs of relay connectors (or supporting members) provided on the front side of a chassis having substantially a plate-shaped configuration. When a discharge tube is supported by relay connectors, stoppers provided on the relay connectors lock the ferrules so that axial movement of the discharge tube relative to the relay connectors is restricted.

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.

An on-board connector 18 includes an output terminal 70 that is surrounded by a housing 60 made of synthetic resin. The output terminal 70 is arranged in an area of the housing 60 farther from the edge portion 17E of a circuit board 17 so that sectional arrangement is provided. The output terminal 70 is thus surrounded by the synthetic-resin housing 60, and thereby a leak at the output terminal 70 can be suppressed. Further, the output terminal 70 is arranged in the limited area of the housing 60 farther from the edge portion 17E of the circuit board 17, resulting in a long distance maintained between the output terminal 70 and the edge portion 17E of the circuit board 17, which can effectively prevent the leak.
