- the base 136 assembled at the end of the discharge tube 115 on the relay connector 114 side is the holder 120.
- the stopper 126 By engaging with the stopper 126, the movement of the discharge tube 115 toward the ground member 150 is restricted.
- the cap 136 engages with the stopper 155 of the ground terminal 152 at the end of the discharge tube 115 on the ground member 150 side. Therefore, the movement of the discharge tube 115 toward the relay connector 114 is restricted.
- the leading end of the water lead 135 is connected to the wall portion on the opposite side of the escape port 125 in the housing chamber 123. There is no risk of hitting the side wall of the chassis 113.
- a recess 156 for abutting the outer periphery of the glass tube 134 in a state in which the cap 136 is locked to the stopper 155 is formed in the stocko 155 of the ground terminal 150, and the discharge tube is formed in the ground terminal 152.
- a pair of elastic pressing pieces 154 capable of pressing 115 toward the concave portion 156 is provided, and the pair of elastic pressing pieces 154 is formed in such a manner that the discharge tube 115 is vertically inclined from the diagonally upper side and the diagonally lower side to the concave portion 156 side. Therefore, it is possible to securely hold the base 136 to the stopper 155 so that the glass tube 134 is not likely to be detached from the recess 156.
- the stopper 155 is formed integrally with the ground terminal 152, which is a means of conduction with the base 136. In the third embodiment, the number of parts is small.
- the insulating portion of the housing is not limited to a substantially block shape in which the housing extends substantially over the entire width, and may have a plurality of protrusions separated in the width direction of the housing.
- the housing may be positioned on the circuit board at a portion other than the insulating part without causing the insulating part to function as a housing positioning means with respect to the circuit board.
- the output terminal is not limited to an elongated shape that is substantially perpendicular to the edge of the circuit board, but has a plate shape parallel to the edge of the circuit board! /.
- the output terminal is not limited to the approximate center position of the housing in the width direction parallel to the edge of the circuit board, but may be arranged in the width direction! Yo! /
- the output terminal may be arranged so as to be biased only in a region of the housing far from the edge of the circuit board, and a part of the output terminal may protrude from the housing.
- connection piece to the outside of the output terminal may be arranged along the outer surface of the housing without being housed in the fitting recess.
- the fitting recess may not be opened on the surface facing the circuit board, but may be opened on the outer surface of the housing other than the surface facing the circuit board.
- the thickness of the housing based on the circuit board of the insulating portion where the output terminal is not disposed may be the same as the thickness of the terminal accommodating portion where the output terminal is disposed.
- the width of the insulating portion of the housing where the output terminal is not arranged may be different from the width of the terminal receiving portion where the output terminal is arranged!
- the edge part on the insulating part side in the terminal accommodating part of the housing may be formed into a right-angled corner edge instead of being cut out in a tapered shape.
- the output terminal may be one in which a metal material is punched into a predetermined shape and is not bent.
- the display panel of the display device is not limited to the one having the switching element force STFT, and the switching element may be other than TFT such as MIM (Metal Insulator Metal).
- the display device is not limited to a liquid crystal display device, and includes various display devices that require a lighting device on the back side of the display panel.
- an insulating material other than the synthetic resin can be used, not limited to the synthetic resin.
