A head lamp with a movable reflector. The headlamp includes a lamp body, a reflector with a light source mounted thereon, and an aiming mechanism interposed between the lamp body and the reflector ( ) for tiltably supporting the reflector ( ) with respect to the lamp body. The reflector tilts by the rotational movement of the aiming screw which is rotatably supported in a screw insertion hole formed on the lamp body. The screw insertion hole is formed by a tubular portion, and the front portion of the tubular portion includes divided swinging strips ( ) which are resiliently deformable in the radial direction. The swinging strips engage with an engaging groove formed on the aiming screw to prevent the aiming screw from being detached from the lamp body. The aiming screw includes a rotatably supported portion formed of resin, a male screw portion, and a gear portion behind the rotatably supported portion. Further, the rotatably supported portion is unitarily formed with a skirt type resilient watertight rib ( ) in pressurized contact, and sliding contact, with the end surface of the backward extension of the tubular portion to ensure the resilient support of the aiming screw in the forward and backward direction and to ensure watertightness at the rotatably supported portion.

Head lamp for automotive vehicle with movable reflector

A retaining projection,for engagement in a retaining groove,formed in a base portion,of a bulb,is formed on one of a pair of holder pieces,of a metal terminal,and a connecting projection,is formed on the other holder piece,and this connecting projection,is to be opposed to that portion of a lead wire,lying between its proximal end portion and its intermediate portion, and is projected toward the lead wire,so as to be held against the lead wire,With this construction, even if the base portion,is held between the holder pieces,and,with the distal end portion of the lead wire,displaced to be tilted, the connecting projection,never fails to be held against the proximal end portion of the lead wire,thereby positively achieving an electrical connection therebetween.

Metal terminal for wedge-base bulb

A vehicular headlamp including a light source bulb, a reflector reflecting light from the light source bulb forward in a convergent manner, a condensing lens provided at such a position that, of the light reflected from the reflector, at least a meridian light flux in a vertical cross-section is incident as divergent light, a shade provided in proximity to a position of convergence of the meridian light flux and which blocks part of the reflected light, and an aiming bracket to which an aiming member for tilting the reflector is attached. The shade is composed of a metal plate member that is formed integrally with the aiming bracket, and is attached to the reflector. With this construction, the total number of parts of the headlamp is reduced and costs can be reduced accordingly.

Vehicular headlamp with integrated aiming bracket

In the bulb socket 1 according to the invention, the connecting terminal 4 to be insert molded within the bulb insertion portion 2 includes the three surfaces, that is, the two side walls 5, 6 having a substantially L-like shape as a whole and the bottom wall 7. In one side wall 5, there are provided not only contact piece 8 and securing piece 9 which can be respectively contacted with the bulb wedge, but also the inflow preventive piece 11 which prevents the flowing-around molding material from flowing into the bulb storage portion 10 and also can strengthen the fixation of the connecting terminal 4 within the bulb insertion portion 2. Also, when molding the bulb socket 1, the fall preventive cores 20 to prevent the deformation of the side walls 5 and 6 are inserted into the bulb storage portion 10 and also into the peripheral portions of the bulb storage portion 10 and, at the same time, the leading end portion 11a of the inflow preventive piece 11 is insert molded within the bulb socket 1.

Bulb socket and method for manufacturing the same

A vehicular lamp which can be manufactured without removing insulating covers from lamp-side cords to expose the core wires, and in which the lamp-side cords can be readily connected between terminals arranged in a socket or connector, the wiring and connecting of the cords is achieved in a short time, and can be automated. A connector and sockets are detachably mounted on a rear cover. The connector includes a connector casing, and a plurality of terminals. Each of the terminals has a cord connecting groove, the edge of which serves as an insulating cover cutting edge. When the connector casing is engaged with a mounting section and secured with elastic engaging pieces, the terminals are caused to push the cords so that the cords are pushed into the cord connecting grooves of the terminals. In this operation, the insulating covers of the cords are cut by the insulating-cover cutting edge, so that the core wires of the cords are electrically connected to the terminals.

Vehicular lamp having improved connector structure

A bulb socket which includes a tubular socket body for receiving a base of a bulb, a positive terminal insertion portion which is formed at the socket body and opens in a direction perpendicular to the axis of the socket body, a positive terminal inserted into the socket body through the positive terminal insertion portion and held at an inner bottom portion of the socket body, and a negative terminal supported on an inner peripheral surface of the socket body. The positive terminal insertion portion extends diametrically of the socket portion and has a length larger than the diameter of the socket portion. The positive terminal has a length larger than the diameter of the socket body, and is supported in the positive terminal insertion portion.

Bulb socket for vehicular lamp

A vehicular lamp having a structure of electrical connection between a lamp bulb serving as a light source installed in a lamp body and an external power source for supplying electric power to the lamp bulb which includes a back cover detachably attached to a bulb insertion hole formed in a back surface of the lamp body and a relay connector connecting with both the lamp bulb and an external power source, and the relay connector is constituted by an internal electrical connection section disposed at an inside of the back cover for electrically connecting with the lamp bulb and an external electrical connection section disposed at an outside of the back cover for connecting with a harness for the external power source. The internal electrical connection section and the external electrical connection section are formed integrally with each other by a conductive terminal which penetrates the back cover.

Vehicular lamps

A horizontally elongated lamp body of a supplemental high mounted stop lamp is fastened to the rear windowpane of a motor vehicle with looseness in the longitudinal direction of the lamp body relative to the windowpane. Molded from a plastic, the lamp body is therefore capable of thermal expansion or contraction in its longitudinal direction without the danger of detachment from the windowpane.

Device for nondetachably mounting a supplemental high mounted stop lamp

A pair of conductive patterns, which are to be electrically connected to the battery of a motor vehicle, are formed as by baking on the interior surface of the rear windowpane of the vehicle. A pair of nuts or brackets of electrically conductive material are soldered to the conductive patterns. The lamp body of a supplemental high mounted stop lamp are fastened to the nuts or brackets, with the light sources of the lamp electrically connected in circuit therewith.

Automobile bulb socket

A connector socket for a wedge-base lamp is improved by socket structures which aid in leading the base end of the bulb into alignment with the insertion channel and at the same time prevent contact between the base end and the top ends of the socket terminals in a way which might lead to wrenching or deformation of the terminals.

Socket for wedge-base lamp

A bulb socket for a wedged-base bulb which can be manufactured at a low cost and yet which is capable of maintaining good resilience of its contact portions over a long period of time. The socket includes a molded-resin body and a plurality of terminals partially embedded in the body as the latter is being molded. Bulb contact parts of the terminals are formed with a wall having an approximately U shape so as to surround the contact portions which pinch the wedged parts of the bulb. The wall preferably extends above the contact portions.
