という問題点があった。However, in the single-base fluorescent lamp socket constructed as described above, the lamp pin 5b is inserted into the contactor 3 and the side surface is clamped so that electrical continuity is established, and the contactor 3 has a front surface of the socket body 2. No force is applied to the side. Further, the base 5 is pushed to the innermost side so as to substantially contact the bottom surface of the locking groove 2d when the locking projection 5d crosses the convex portion 2g when the single-base fluorescent lamp is mounted, and the state thereof is maintained. Then, the lamp pin 5b is pushed to the position where it can be inserted into the contact 3 most deeply, but thereafter, the push button 7 is pushed back to the front side of the socket body 2 by the spring 9 for urging the push button 7 toward the front side of the socket body 2 and locked. Since the lamp pin 5b moves away from the bottom surface of the groove 2d, when the mounting is completed, the lamp pin 5b moves from the most inserted state in the direction of coming out of the contactor 3 by the pushed-back distance d1 and the state Is clamped by the contactor 3 and locked. Therefore, there is a problem that the axial distance between the lamp pin 5b and the contactor 3 in contact with the lamp pin 5b is shortened, and the contact area between the lamp pin 5b and the contactor 3 is narrowed.

う問題点があった。Further, like the conventional single-base fluorescent lamp socket, when the single-base fluorescent lamp 1 is mounted, the locking projection 5d is provided between the insertion hole 2e and the locking hole 2f of the socket body 2. Since it is necessary to get over the convex portion 2g projecting to the back side, at least the locking projection 5d is convex between the bottom of the storage recess 2a of the socket body 2 and the bottom surface 5a of the base 5 after the mounting is completed. The amount of movement of the base 5 in the lamp axial direction when the vehicle goes over the portion 2g and reaches the locking position (the socket body 2 of the locking projection 5d

Is inserted into the storage recess 2a and then rotated to move the locking projection 5d from the insertion hole 2e to the locking hole 2f side in the locking groove 2d. At this time, when the locking projection 5d of the mouthpiece 5 is pushed into the insertion hole 2e of the locking groove 2d and starts to rotate, the height of the locking projection 5d and the height of the locking hole 2f become smaller. Since they are almost the same, the locking projection 5
The front surface side of d abuts on the front wall surface of the locking hole 2f, and as shown in FIGS. 3 to 5, the locking spring portion 10b is pressed by the locking projection 5d to start elastic deformation. When the locking projection 5d gets over the locking spring 10b and comes into contact with the bottom surface 2n on the side of the locking hole 2f, the locking spring 10b returns to its original state by elasticity, and the locking hole 2f side. The projection of the bottom surface 2n of the single base fluorescent lamp 1 is completed in this state. That is, when the locking protrusion 5d gets over the rotation stopper 10, the locking projection 10d pushes the rotation stopper 10 substantially below the bottom surface 2n of the locking hole 2f so as to get over the locking stopper 5d. The front surface side of the protrusion 5d abuts on the front wall surface of the locking hole portion 2f so that the base 5 does not move to the front surface side of the socket body 2. At this time, the lamp pin 5b is inserted into the contactor 3 from the side surface side by the rotation of the base 5, and is held by the elasticity of the contactor 3 so as to sandwich both side surfaces thereof to establish conduction.

Is the locking projection 5d due to the rotation of the single base fluorescent lamp 1 when it is mounted.
When moving from the insertion hole portion 5e side to the locking hole portion 2f side, there is almost no movement toward the front surface side of the socket body 2 which is the insertion direction of the mouthpiece 5 into the storage recess 2a. The lamp pin 5b also does not move from the most pushed state to the back side of the socket body 2 in the opposite direction, that is, the pulling-out direction, and the length of the portion of the lamp pin 5b held between the contacts 3 can be increased. , Lamp pin 5
Since the contact area between b and the contactor 3 can be widened,
Contact reliability is improved. Further, since the side surface of the lamp pin 5b is clamped to establish electrical connection with the contactor 3, the contact is more stable than the tip of the lamp pin 5b, and the contact reliability is further improved. Furthermore, when the locking projection 5d moves from the insertion hole 2e to the locking hole 2f, it is almost unnecessary to move the base 5 to the front side of the socket body 2, so that the lamp in the storage recess 2a is not moved. It is not necessary to provide a space for the movement in the axial direction, and it is not necessary to provide a space for avoiding the lamp pin 5b in the storage portion 2k that is inserted to the rearmost side, so that the size can be reduced.

Since the locking spring portion 10b of the rotation stopper 10 projects to the insertion hole 2e side of the locking hole 2f, the locking projection 5d inserted and locked in the locking hole 2f is inserted. Inadvertent rotation to the hole 2e side can be prevented, and the single-base fluorescent lamp 1 can be reliably held. Further, since the rotation stopper 10 is formed of the elastic metal member, when the rotation stopper 10 elastically deformed when the lamp is mounted is restored, a clear sound can be emitted to recognize that the mounting is completed. In addition, it is possible to prevent an incompletely mounted state from occurring, and since the rotation stopper 10 is formed of an elastic metal member and the resin-made locking projection 5d slides on the rotation stopper 10, it is possible to apply the resin to each other. The frictional resistance between them is smaller than that in the case of contacting them, and the rotating operation can be performed smoothly. Furthermore, lamp pin 5
Since b does not move from the most pushed state to the back side of the socket body 2 in the opposite direction to the withdrawal direction, the lamp pin for obtaining the same contact area between the lamp pin 5d and the contactor 3 The length of 5d can be shortened and the cost can be reduced.

なって小型化が図れる。As described above, according to the present invention, since it is configured as described above, the locking projection is formed on the side of the insertion hole by the rotation of the base when the single-base fluorescent lamp is mounted. When moving from the to the locking hole side, there is almost no movement to the front side of the socket main body, which is the direction of inserting the base into the storage recess, and therefore the lamp pin is also most likely to move to the rear side of the socket main body. Since it does not move from the pushed state in the opposite direction to the withdrawal direction, the length of the part clamped by the contact of the lamp pin can be lengthened and the contact area between the lamp pin and the contact can be widened. As a result, the reliability of contact is improved. Moreover, since the side surface of the lamp pin is clamped to establish continuity with the contact, the contact is more stable than the tip of the lamp pin, and the contact reliability is further improved. Furthermore, when the locking projection moves from the insertion hole to the locking hole, it is not necessary to move the base in the lamp axial direction. Since it is not necessary to provide a space, the size can be reduced. Can be miniaturized by eliminating the problem.
