Definitions
- the present invention relates to a lamp socket for lighting equipment such as a headlight of a vehicle and a projection light in industrial equipment.
- a lamp that emits a strong light beam is used to illuminate a considerable distance with high illuminance.
- Halogen lamps are commonly used as lamps for irradiating this intense light beam, but recently, HID lamps (high-intensity discharge lamps) have been developed worldwide.
- the HID lamp with high intensity as compared with the halogen dancing is obtained, but c has advantages such as power saving can be expected, the illumination control circuit for lighting the HID lamp, a voltage regulator, the discharge start To achieve this, an igniter that applies a considerable high voltage to the lamp at the time of lighting is used. Because of the need for such a high voltage, the lamp socket that holds the HID lamp needs to have considerable insulation properties.
- FIG. 15 is a schematic diagram of a headlamp system.
- Left and right headlamp housings H are provided below a front portion of a bonnet B in a front vehicle body.
- Each headlight housing H has a concave reflector that is open forward, and a lamp holder or socket S attached to the bottom of the reflector R.
- the electrodes of the Rambus socket S are connected to a power source via an igniter IG and an inverter INV.
- Fig. 16 shows the lamp socket S shown in Fig. 15 and the lamp socket S.
- the HID lamp L in the inserted state is shown in a perspective view.
- the HID lamp L includes an arc tube 103, a cylindrical base 105 having a flange 104 formed at an end near the arc tube 103, and a base 105.
- a central electrical contact 106 which extends outwardly concentrically with the base 105 at the end opposite to the collar 104 and is surrounded by a protective skirt 105a,
- a peripheral electrical contact 107 attached to the base 105 so as to surround the electrical contact 106, and at least two lub mounting pins 1 extending outward from the outer peripheral surface of the base 105.
- Such HID lamps L are well known.
- the lamp socket S is configured to support the lamp L when the HID lamp L is inserted with the base 105 facing.
- the conventional lamp socket S has a substantially cylindrical shape having a lamp mounting opening 109 at one end and an end wall closed at the other end. Consisting of 110 casings. Inside the casing 110 facing the opening 109, there are a central electrode 1 1 1 and a peripheral electrode 1 1 2 which make electrical contact with the central electrical contact 106 and the peripheral electrical contact 107 of the lamp L, respectively. And are arranged. At least one pair (but two pairs are shown in the figure) of L-shaped mounting grooves 114 are formed in the end wall of the casing 110 facing the opening 109.

- the lamp replacement in a car is usually performed by turning off the power, but it is necessary to turn on the power in order to check whether the new lamp has been turned on. When the power is turned on in this way, but the replaced lamp does not light up for some reason, it is possible to forget that the power is on and play with the lamp-lamb socket.
- the center electrode and the peripheral electrode are always exposed through an opening of the casing, and are in a state of being touched by a finger. Therefore, as described above, there is a danger of a ground fault or a short circuit if metals enter the opening while the power is on. If the lamp is an HID lamp, an igniter that generates a high voltage is used to start the lamp. Such problems cannot be ignored due to accidents and short-circuiting due to internal discharge in the lamp socket.
- a high-voltage pulse is applied at the time of lighting. Therefore, when the igniter is turned on when the lamp is not mounted, a high voltage pulse is supplied to the electrodes of the lamp socket, and discharge occurs between the electrodes.

- the connecting piece 3d is formed so as to have a substantially horseshoe shape when the lamp socket S is viewed along its longitudinal axis. This connecting piece 3 d is formed by the peripheral electrode 3
- the size and shape are determined so as to be inserted into a substantially horseshoe-shaped gap formed between the outer cylinder 31 and the inner cylinder 32 of the 30.
- the peripheral electrode piece 3 c becomes the inner cylinder 3 2 extends in the longitudinal direction along the outer periphery of the inner cylindrical body 32, and the inside of the inner cylindrical body 32 extends through a groove 32a formed in the inner cylindrical body 32, as shown in FIG. And partially project radially inward. Therefore, when the base 105 of the lamp L is inserted into the lamp mounting opening 5 of the lamp socket S, the insulating nest 40 is opposed to the coil spring 15 by the protection scut 105a of the base 105.
- the central electrical contact 106 contacts the central electrode 2, and the peripheral electrical contact 107 contacts the peripheral electrode 3 while being moved from the projecting position to the retracted position.
- the central electrode piece 2a reliably contacts the central electrical contact 106 with its own elastic force, and the peripheral electrode piece 3c moves the peripheral electrical contact 107 from the direction opposite to each other in the radial direction. The contact is ensured by its own elastic force.
- the lid 29 may be a simple disk-shaped wall member, but in the illustrated embodiment, the lid 29 also serves as the lid of the electric wire holding box 24 integrally formed with the outer cylinder 31 of the casing 30.
- a flap 29 a serving as a lid of the wire holding box 24 is integrally formed in a lower portion of the end lid 29 when viewed from FIGS. 9 and 10, and the flap 29 a
- a hook member 29b extending substantially parallel to the longitudinal axis of the casing 30 is formed.
- the end wall 29 has a flange formed by cutting out a portion corresponding to the flap 29a, and the end cover 29 is attached to the rear end of the casing 30. 3 It fits in sliding contact with the inner peripheral surface. Therefore, even if only the attachment by engagement of the hook member 29 b and the engagement piece 24 a is performed, the end cover 29 rotates about the longitudinal axis with respect to the casing 30. There is no.
- 9 c is also formed substantially at the center of the end cover 29 so as to extend toward the center electrode 2.
- connection line 113 extending inside the electric wire holding box 24 is received in a substantially zigzag groove inside the electric wire holding box 24. Even if a tensile force acts on 3, the tangent line 113 does not deviate.
- the lamp socket S When the lamp L is not installed, the lamp socket S is in the state shown in FIG. That is, the insulating nest 40 is maintained at the projecting position as shown in FIG. 10 by the urging force of the coil panel 15. At this time, the center electrode piece 2a always facing the inside of the sleeve 51 of the electrode carrier 50, and the outer end of the inner cylindrical body 32 of the casing, Only between the peripheral electrode piece 3 c partially facing the inside of the inner cylindrical body 32 through the groove 32 a formed in the inner cylindrical body 32, an insulating nest 40 sleeve 4 is provided. There is a double wall of the rear end 1 and the skirt 42. Therefore, since this double wall acts as an insulator, even if a high voltage pulse is accidentally applied to the electrode of the lamp socket S when the lamp is not mounted, a discharge is generated between the central electrode 2 and the peripheral electrode 3. Is almost none.
- the central electrode piece 2 a captures the central electrical contact 106 of the lamp L, while the central electrode piece 2 a catches the groove 3 2 a of the inner cylinder 32.
- the leading end portion of the surrounding peripheral electrode piece 3c comes into contact with the peripheral electric contact 107 of the lamp L by its own elastic force. After this state is achieved, the lamp L is rotated around the longitudinal axis of the casing 30 to complete the mounting of the lamp L on the lamp socket S.
- the tip of the sleeve 41 is flush with the tip of the outer cylinder 31 of the casing 30.
- the length may protrude outward from the tip of the cylindrical body 31 or may be a length facing the inside.
- the casing 30 has a structure in which the outer cylinder 31 and the inner cylinder 32 are integrally formed, instead of the outer cylinder 3 and the inner cylinder 3 2 ′ as shown in FIG.
- the member may have a structure in which the inner cylinder 32 'is inserted into the outer cylinder 3' and fixed.
- the center electrode carrier 50 and the end cover 29 may be formed integrally. As another method, after the center electrode carrier 50 and the end cover 29 are separately formed, they may be integrated by bonding or fusing them. In the modification shown in FIG. 14, the casing 30 and the center electrode carrier 50 are integrated. Even in this case, they may be integrated at the time of molding, or they may be bonded or fused after being molded separately.
- the center electrode carrier is not only a casing but also a separate part from the insulation nest, it is necessary to connect the connecting wires, to use the insulation nest and the casing of the coil panel. Temporary holding becomes easy, and the socket assembly can be promoted.
- the present invention has great industrial applicability due to the above-mentioned structural features.
