Definitions
- the present invention relates to the field of sockets for filament lamps with a glass base. More particularly, the invention relates to a lampholder for glass base suitable for use in lighting and / or signaling devices for motor vehicles, including traffic lights.
- These clip-on sockets are in the bottom of the lighthouse or the fire, and receive bulbs with glass base ("wedge-base lamp” in English) powered through contacts crimped on electrical cables.
- bushings constituted by an insulating tubular body made of molded plastic are known. These sockets are intended to receive W5W type lamps, for the night light function in automotive headlights. These bushings present in a known manner two longitudinal cells in which are inserted electrical contacts crimped on power cables.
- the socket according to the state of the art is inserted into the bottom of the headlight, which has an opening for this purpose.
- the socket known in the state of the art has resiliently deformable side tabs, with external shoulders to ensure clipping.
- bushings are used as follows: the lamp is inserted into the socket by pressing it in such a way that the base and the electrical contacts are engaged on the contacts of the socket. The socket carrying the bulb is then engaged in the lighthouse.
- European Patent EP0404135B1 describes a bushing intended to be mounted on an electrically insulating substrate.
- This socket according to includes hook-shaped electrical contact blades and a sheath for holding the base of the lamp in the socket.
- Patent Application EP1633024 is also known, describing a socket for a lamp with a glass base comprising a base and at at least two electric contact blades mounted in said base for electrically connecting electrodes of the lamp to a power supply circuit, said electrical contact strips each having an elastic portion forming a clamp in which said lamp base is inserted into the lamp .
- the base comprises a centering piece made in the form of a ring extending on a first face, by at least one lug adapted to ensure a fixed positioning of said centering piece.
- centering elements form a part in contact with the base of the bulb of the lamp in order to center the lamp in the base in a predetermined manner and to oppose a movement of the lamp relative to the base .
- European patent EP066863 also discloses a bulb socket comprising a W5W type bulb receptacle.
- Sockets according to the state of the art have the disadvantage of allowing mounting with an imperfect electrical connection. It may happen that one of the crimp contacts is not properly locked in the slot of the socket, which causes power supply faults of the lamp. Even if a preliminary electrical control is carried out, the imperfect locking may lead to the lamp being considered transiently as properly energized, and then, after shaking or vibration, to be released.
- the present invention aims to overcome this disadvantage by proposing a bushing improve, preventing the mounting of the socket on the headlight when the electrical contact is not fully engaged.
- the invention provides an additional advantage in ensuring double locking of the contacts once the socket is mounted on the headlight.
- the present invention relates, in its most general sense, to a socket for a light bulb constituted by a tubular body having two longitudinal cells for receiving contacts crimped onto a cable, said tubular body having clipping lateral lugs having shoulders for locking in the bottom of a headlight or an automobile light, characterized in that said locking tabs have an internal shoulder whose dimensions and positioning are configured to engage behind a transverse surface of the contact, when it is correctly mounted, and when said tab is urged to allow insertion into said bottom of the headlight or fire, and to prevent the movement of the tab for the insertion of the socket, when the contact n ' is not properly engaged.
- said shoulder of the tab releases the passage of the cell at rest.
- said shoulder of the tab is configured to ensure the locking of the contacts by the conjugation between the transverse surface of the shoulder and the transverse surface of the contact, when the contact is properly engaged in the socket and when the socket is clipped in. the bottom of the lighthouse or the fire.
- said tabs are molded in the spaced apart position, and have elastic hooks engaging in a complementary zone of the tubular body during the first transverse stress on said tabs.
- said tabs are molded in the spaced apart position, and have rigid hooks engaging in an elastic complementary zone of the tubular body during the first transverse stress on said tabs.
- FIG. 1 represents a three-quarter rear view of a socket according to the invention
- FIG. 2 represents a cutaway perspective view of the socket, when the electrical contact is badly engaged.
- FIG. 3 represents a cutaway sectional view of the socket, when the electrical contact is badly engaged
- FIG. 4 represents a cutaway perspective view of the socket, when the electrical contact is correctly engaged
- FIG. 5 shows a cutaway sectional view of the socket, when the electrical contact is poorly engaged, being inserted in the lighthouse
- FIG. 6 shows a cutaway sectional view of the socket, when the electrical contact is correctly engaged and the socket is engaged in the headlight.
- FIG. 1 shows a view of the bushing, after the engagement of the contacts and before the first biasing of the side tabs (1, 2) extending on either side of a substantially tubular insulating body.
- FIG. 1 schematically represents a bulb (4), in a position that it would have after final assembly.
- the bushing is molded in two mold directions only.
- the front portion of the tubular body (3) has a sectional cavity complementary to that of the bulb (4).
- the sleeve has two longitudinal cells (5, 6) disposed on either side of the main axis. These cells (5, 6) are intended to receive the crimped contacts (7, 8). In the example described, the contacts are each crimped on two supply son (9, 10, 1 1, 12) forming a beam for feeding other equipment.
- the contact (8) shown more clearly in FIG. 2, is produced by cutting and folding a sheet of elastic cuprous alloy.
- This front portion (13) has a front portion (13) in the form of clamp or lyre which is fixed on the base of the bulb (4) to provide power to one of the electric pins of the bulb.
- This front portion (13) has a locking nose (14) elastically deformable.
- This nose (14) is housed in a housing (15) provided on the tubular body (3) when the contact is normally engaged. This nose (14) then maintains the contact in the active position, and prevents the contact is pushed back when the bulb is engaged or when traction is exerted on the supply son.
- the front portion of the contact (13) further has a stop (16) which comes against a face (17) of another lumen (18) provided on the tubular body (3).
- the tabs (1, 2) are articulated at a refined zone (19, 20) forming a folding zone. It has lugs (21, 22) locking on the bottom (23) of the headlight as shown in Figure 3. At the rear of these lugs (1, 2) is provided a gripping area (24, 25) allowing to exert a diametrical force facilitating removal of the socket from the bottom of the headlight, for example for the replacement of a defective bulb.
- the tabs also have two hooks (26) cooperating with two complementary zones (27) during the first activation, by the exercise of a diametric force on the gripping area (24, 25). This first activation is done during assembly, after the introduction and locking of the contacts (7, 8).
- the lugs (1, 2) have at their inner surface shoulders (28) visible in Figure 1 and 2, positioned to cooperate with a detection zone (29) of the contacts (7, 8).
- the rear of the detection zone (29) provides a retaining zone (30) abutting against the shoulder (28) when the contact is correctly engaged and locked.
- each contact is thus doubly locked, each of the tabs detecting the positioning of one and the other of the contacts, and also ensuring the locking of one and the other of the contacts.
- Operation of detection and locking Figure 2 illustrates the situation when one of the contacts (8) is not fully engaged and is not locked.
- the locking nose (14) is not engaged in the housing (15), and the stop (16) is not against the face (17) of the light (18).
- the tab (1, 2) has a shoulder (31) in front of the chamfer (32) preceding the pin (21).
- the shoulder (28) of the tab (8) passes behind the retaining faces (30) of the contacts (7, 8), when it exerts a diametric stress on the tabs (1, 2).
- the four hooks (26) of the legs (1 and 2) are simultaneously engaged against the four complementary zones (27).
- Figure 5 shows the sleeve (3) during the passage in the bottom (23).
- the shoulder (28) does not limit the stroke of the leg, which can deform sufficiently to allow passage of the bottom (23) of the headlight.
- Figure 6 shows the view of the socket in mounted position. The shoulder (28) provides a secondary locking of the contact and secures the mounting.
