Problems solved by technology

However, in the invention described in JP Unexamined Publication No. 5-165085, the elastic metal plate connected to the electrodes must be welded to the circuit board. In addition, in the invention described in JP Unexamined Publication No. 8-297312, Electrodes and flat terminals are welded together
These welding operations are time-consuming and labor-intensive, so although the damage to the flash discharge tube 1 can be reduced, the assembly work is difficult.

Abstract

The present invention provides a discharge tube connector which suppresses the occurrence of a damage of a discharge tube at the time of installation and can be easily installed. An end electrode (10a) of the discharge tube (10) and a board electrode on a circuit board can be electrically connected with each other through a conductive connection portion (8) without using lead wires, so a damage such as a crack and the like, of a light-emitting portion (10b) of the discharge tube (10) can be avoided. When a holding portion (6a) is made of a rubber-like elastic material, the conductive connection portion (8) has rubber-like elasticity, so the conductive connection portion (8) can be pressed between the end electrode (10a) and the board electrode on the circuit board to conductively connect the end electrode (10a) with the board electrode. Therefore, the soldering operation can be omitted. Thus, installation does not take time, so a manufacturing cost can be reduced.

Description

technical field [0001] The present invention relates to a discharge tube connector for electrically connecting a discharge tube such as a flash discharge tube to a current substrate and holding the discharge tube. Background technique [0002] Many lighting devices have a discharge tube as a light source. For example, a flash device used for camera photography has a straight tube-shaped flash discharge tube, a circuit board, and a reflector, and condenses light emitted by the flash discharge tube onto the reflector to illuminate a subject. A conventional example of such a flash device is specifically described using FIG. 25. In this flash device, an end electrode 2a protruding from a light-emitting portion 2b of a flash discharge tube 1 as a pin terminal is inserted and held so as to surround the flash discharge tube. The reflector 3 provided in the form of the tube 1 is connected electrically by soldering the lead wire 4 extending from the end electrode 2a to the circuit b...
