DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp socket applied to a headlight device for a vehicle and the like.

[0002]

2. Description of the Related Art FIGS. 28 and 29 show a conventional example. That is, 69 is a socket body, 70 and 71 are contact terminals,
Reference numeral 72 denotes an electric wire connected to a lighting device (not shown), 73 denotes a high-pressure discharge lamp (HID lamp), 74 denotes an arc tube, 75 denotes a base, 76 denotes a center electrode, and 77 denotes a peripheral electrode.

The lamp socket has a bayonet-type lamp mounting structure. A lamp holding pin 78 of a base 75 is inserted along an L-shaped mounting slit 79 of the lamp socket, and is subsequently rotated to hold the lamp 73. The base 75 is attached to the lamp socket as shown by the imaginary line in FIG. 29, the center electrode 76 fits into the contact terminal 71, and the peripheral electrode 77 contacts the contact terminal 70. A high-voltage pulse from the lighting device is applied between the center electrode 76 and the peripheral electrode 77 through the contact terminals 70 and 71, and the arc tube 74 starts discharging to stably light. When the high-pressure discharge lamp is normally turned on stably and then turned off, it is difficult to restart even if the power is turned on again. However, when a very high voltage is applied at this restart, instantaneous start-up is possible.
This lamp socket can also be used as a lighting device that can be restarted instantaneously.
The voltage is applied to both ends of the arc tube 74 through 77.

[0004]

However, the lamp 73
The positional relationship between the peripheral electrode 77 of the base 75 and the lamp holding pin 78 is determined in a base shape, and the contact terminal 70
Is located just inside the mounting slit 79, so that when a high voltage is applied to the peripheral electrode 77, when the lamp body and the lamp body are separated from each other at the time of lamp replacement or the like, as in a vehicle headlight device, the outer periphery of the socket body 69 In the case of the conventional structure, it is dangerous to generate a high-voltage pulse at the time of starting.

Also, when the socket body 69 is removed from the lamp 73, unless the original switch is turned off, there is a danger of touching the charged part and receiving an electric shock. Particularly, an HID lamp having a starting pulse of several kV or more is dangerous. For this reason, in the conventional lighting device, the generation of the high-voltage pulse is limited to only the center electrode 76. However, if the lead wire 72 connecting the lighting device and the lamp socket is erroneously connected in reverse, the insulation distance becomes insufficient.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lamp socket which can prevent electric shock or the like when replacing a lamp and can achieve safety.

When the socket body 1 is mounted on the lamp 73 by rotating, the concealing body 2 is easily gripped, and the socket body 1 is easily rotated and mounted. Others are the same as the proposal example .

FIG. 5 shows a second embodiment of the present invention. That is, this lamp socket has the lead wire lead-out portion 9 in the concealing body 2 in the first embodiment. According to this embodiment, since the lead wire protrudes from the vicinity of the lamp mounting portion, it is difficult to touch the peripheral portion of the lamp holding pin 78 with a hand, and a more secure structure is obtained. Others are the same as the first embodiment.

FIGS. 6 to 8 show a third embodiment of the present invention.
Shown in That is, in this lamp socket, in the proposed example , the concealing body 2 is movable in the lamp attaching / detaching direction with respect to the socket body 1 and the lamp holding pin 78 (FIG. 28).
Covers the mounting slit 5 in a state where the mounting slit 5 is engaged with the mounting slit 5. In the embodiment, the concealing body 2 is formed of an insulating ring in the same manner as the proposed example, and the concealing body locks the locking receiving portion 17 where the locking claw 11 elastically locks at the position where the concealing body 2 covers the mounting slit 5. It is formed in the portion 8. Reference numeral 18 denotes a ring-shaped ridge provided on the side of the opening 3 of the socket body 1 of the locking receiving portion 17, which locks the locking claw 11 to prevent the concealing body 2 from being pulled out. Reference numeral 18a denotes a guide of the locking claw 11 when the concealing body 2 is fitted to the socket body 1.

FIGS. 6 and 8 show a state in which the mounting slit 5 is covered with the concealing body 2. At this time, the locking claws 11 are locked in the locking receiving portions 17.

Projecting more outward, and in a lamp mounted state, pressed by the base to press the contact terminal against the electrode of the lamp, thereby preventing exposure of the electrode of the lamp,
The electrode can be easily waterproofed, the contact pressure between the electrode and the contact terminal can be increased, and loose contact can be prevented.

[0060] According to the lamp socket of claim 9, wherein
In addition to the effects substantially similar to those of the above item 1, the socket body has a pair of contact terminals at the center thereof, the base has a pair of lamp holding pins, and the lamp holding pins and the contact terminals are arranged in one diameter direction. The center electrode and the pair of contact terminals can stably contact with each other with respect to the inclination of the lamp. Also, when the lamp socket is used in a vehicle, the center electrode of the lamp vibrates vertically, but by arranging a pair of contact terminals for fitting the center electrode in the horizontal direction, the contact terminals are less likely to receive the force of vibration. There is no spring set.

According to the lamp socket of the tenth aspect, in the ninth aspect , the contact terminal in the vicinity of the mounting slit is arranged in a diameter direction orthogonal to a direction in which the lamp holding pin and the contact terminal are arranged. Claim 9
In addition to the above-mentioned effects, the contact terminals in the vicinity of the mounting slit can increase the resilience, so that by arranging them vertically, the base of the lamp is clamped, so that the lamp can be easily moved up and down and vibration of the lamp can be prevented.
