DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp socket and a lighting fixture.

[0002]

2. Description of the Related Art In a conventional butt type lamp socket, all four lamp pins of a lamp base come into contact with a conductive plate when a lamp is inserted.

On the other hand, in a conventional lamp socket of a plug-in type, in which a lamp pin is sandwiched between conductive plates, the lamp pins are brought into contact with the conductive plate only by inserting the lamp pin and rotating the lamp.

[0004]

The lamp socket of the butt type is turned on before mounting the lamp with the lamp inserted when the lamp is mounted with the power supply connected. There is the danger that the lamp will be dropped, or the lamp will be accidentally removed from the lamp, and the lamp will be dropped.

[0005] In addition, the operability of the conventional lamp sockets of the butt type and the insertion type is inferior because the lamp must be rotated while being pushed without holding the lamp only by inserting the lamp.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a lamp socket and a lighting fixture which do not turn on the lamp when the lamp is inserted and which can temporarily hold the lamp and which is easy to operate and remove.

[0007]

According to a first aspect of the present invention, there is provided a lamp socket, comprising: a socket body; and a conductive member provided in the socket body and in contact with a lamp pin of a lamp base. A lamp socket adapted to be mounted by rotating in a direction, wherein when the lamp pin is inserted into the socket body, at least one other of the lamp pins is held and at least one of the lamp pins is not in contact with the conductive member. It is characterized by having comprised so that it might become.

According to the lamp socket of the first aspect,
At least one lamp is held with the lamp inserted, and at least one of the lamps is not in contact with the conductive member. Therefore, the lamp does not light up, so there is less risk of releasing the hand from the lamp. Since the lamp is held, the lamp can be prevented from dropping and safety can be improved. Further, it is easy to determine that the lamp is not in a proper mounting state because the lamp pin is not inserted just by inserting the lamp pin.

According to a second aspect of the present invention, in the first aspect, the conductive member holds two or more of the lamp pins when the lamp is inserted.

According to the lamp socket of the second aspect,
In addition to the same effect as the first aspect, since the lamp is temporarily held by the two conductive members, two out of four conductive members can be used in common.

According to a third aspect of the present invention, there is provided a lamp socket according to the second aspect, wherein a pair of conductive members arranged symmetrically with respect to the rotation axis of the lamp base hold the lamp pin when the lamp is inserted.

According to the lamp socket of the third aspect,
There is an effect similar to that of the second aspect.

According to a fourth aspect of the present invention, there is provided the lamp socket according to the first aspect, wherein a conductive member that comes into contact with the lamp pin by a rotating operation of the lamp has a different position where the conductive member comes into contact with the lamp pin.

According to the lamp socket of the fourth aspect,
In addition to the same effects as in claim 1, the force required to contact the conductive member during rotation is dispersed compared to the case where all the conductive members are at the same position during rotation for mounting the lamp, so the rotation operation force is reduced. it can.

According to a fifth aspect of the present invention, in the lamp socket of the first, second, third or fourth aspect, the conductive member sandwiches and holds the lamp pin.

According to the lamp socket of the fifth aspect,
There is an effect similar to that of claim 1, claim 2, claim 3, or claim 4.

A lighting apparatus according to a sixth aspect uses the lamp socket according to the first, second, third, fourth, or fifth aspect.

According to the lighting apparatus of the sixth aspect, the same effects as those of the first, second, third, fourth or fifth aspects are obtained.

And the lamp pin 23 is attached to the socket body 1 by rotating in one direction. In the embodiment,
When the lamp pins 23 are inserted, the two lamp pins 23 are held. In this case, a pair of conductive members 15a and 15c arranged symmetrically with respect to the rotation axis of the lamp base 17 hold the lamp pin 23 when the lamp is inserted. Each of the conductive members 15a to 15d has a structure in which the lamp pin 23 is held therebetween. That is, the conductive members 15a to 15d are
When the conductive members 15a and 15c symmetrical with respect to the rotation center of the lamp base insert the lamp pin 23 into the lamp pin insertion hole 9 as shown in FIG. This is maintained, and the conductive members 15b and 15d are configured so as to be in non-contact with the lamp pin 23. Therefore, in this state, even if the power supply is connected to the quick connection terminal 7, the lamp has no problem, and the conductive members 15a and 15c and the lamp pin insertion hole 9 are provided.
Tentatively held between the edges. Next, when the lamp base is rotated in the direction of the arrow in FIG.
To the position B, and all the lamp pins 23 are inserted into the conductive members 15a to 15d in the lateral direction and are clamped. As shown in FIG. 3, the structure of the conductive members 15a to 15d is as follows.
The holding pieces 11a and 11b are opposed to each other from a and 10c, and the holding pieces 11a and 11b are bent in a direction in which the tip and one side are separated from each other. It can be easily inserted between the holding pieces 11a and 11c from either side. A bent piece 12 is bent at the end of the piece 10d opposite to the extending direction of the holding pieces 11a and 11b, and the wire insertion hole 1 is inserted into the bent piece 12.
2a is formed, and a locking portion 13 is provided at the tip of the bent piece 12 to approach the piece 10d. The conductive members 15a, 15
c is a pair of holding pieces 11a, 1 when the lamp pin 23 is inserted.
It may be arranged so as to be held and held by 1b.
