Definitions

  • the invention relates to lamp holders for motor vehicle, especially for headlights and lights signaling.
  • the city lamp is supported by a clean lamp holder which has two housings intended to receive two contact elements electric connected to two beam conductors vehicle.
  • the contact elements have a elongated flat shape, the housings having a corresponding hollow.
  • the contact elements are introduced into the homes following their direction longitudinal by an axial end of the housing.
  • Each contact element has a lug of locking inclined to the general plane of the contact element and directed to the rear of the contact element. At the end of the introduction to the contact element in the housing, the lug comes in abutment against a relief on the internal face of the housing to prevent the contact element from coming out.
  • WO-A-86/01 041 describes a lamp holder suitable for receiving electrical contact elements and a lock adapted to be attached and immobilized on the lamp holder by preventing the exit of the elements of electric contact.
  • the lock cannot be placed in closed position if the contact element is in a wrong position in the lamp holder because the contact hinders the installation of the lock. Setting closed position of the lock therefore guarantees correct mounting of the contact element.
  • this lamp holder can be mounted on a motor vehicle headlamp without that the lock is present. Therefore, if the presence of the lock on the lamp holder is not checked when mounting the lamp holder on the projector, nothing only ensures that the contact elements are properly in position in the lamp holder.
  • An object of the invention is to overcome this disadvantage and increase the assurance of an assembly correct contact element in the projector or fire.
  • a combination of a lamp holder and a reflector for a motor vehicle comprising a body adapted to support at least one lamp, the body having at least one housing having an opening and adapted to receive at least one element electric contact through this opening, the lamp holder comprising at least one lock adapted to have a closed position in which it extends into the opening, and an open position in which it extends away from the opening, the lamp holder being suitable for occupying an installation position in a recess of the reflector, the lock being fixed to the body being movable relative to it between the position open and closed position, the lamp holder and the reflector being arranged so that when the latch is not in the closed position, the bulb holder has a size making it unfit to occupy the position mounting in the reflector.
  • the lock is in closed position on the body for installation of the lamp holder in the reflector.
  • the contact element is suitably arranged in the spotlight or fire completed.
  • the body comprises a part of stop adapted to come into abutment against the reflector in mounting position of the lamp holder in the reflector, the abutment part having at least one cut in which the lock fits in the closed position.
  • the lock extends in position open outside the stop part.
  • the abutment part is flared.
  • the lamp holder includes latching means on the body of the or each lock in closed position.
  • the or each lock can be connected to the body at by means of a hinge.
  • the or each lock may be one part with the body of the lamp holder.
  • the combination comprises a electrical contact element adapted to be received in the body housing, the lock being adapted in position closed to form an obstacle to an exit of the element of electrical contact of the housing, being contiguous to the item.
  • the or each lock may have two parts arranged to extend in the closed position of the latch in the exit path of the element contact, being contiguous to the contact element and arranged on either side of an electrical conductor attached to the contact element.
  • the lamp holder may include two elements of contact. It may have two locks.
  • a lighting or signaling device such as headlamp or light for a motor vehicle, comprising a combination according to the invention.
  • the combination according to the first embodiment shown likewise that of the second mode, is intended for a projector motor vehicle with a main lamp and a city lamp.
  • the combination here includes a lamp holder, a reflector 7 and two contact elements electric.
  • the lamp holder is designed to support in own the city lamp 2, the projector comprising elsewhere another lamp holder to support own the main lamp.
  • the lamp holder has a body 4 made of material injection molded plastic.
  • the body has a cylindrical part 3 and a flared part 5 taking birth at one end of the cylindrical part.
  • the flared part 5 a in plan, that is to say in view end, a generally rectangular shape like the shows figure 2.
  • the width of the rectangle is close the diameter of the cylindrical part 3.
  • the part cylindrical 3 supports the lamp 2 at one end axially opposite to the flared part.
  • the part cylindrical 3 is intended to be introduced into a recess of the reflector 7 of the projector, the part flared 5 abutting outwardly against the reflector 7 to limit this introduction, as shown on the right side of figure 1.
  • the cylindrical part 3 has two housings 6, 8 parallel elongated having an end opening and intended to receive through these openings two elements of metallic electrical contact 10.
  • Each element of contact 10 conventionally has a generally flat shape elongated with rectangular contours.
  • An extremity rear 12 of the contact element is narrowed.
  • She is connected to a power supply conductor 14 by being fixed by crimping thereto.
  • the element contact has a recess and a lug 16 extending into the recess being inclined relative to at the plane of the contact element so that it extends projecting from one face of the contact element. Ergot is directed towards the rear end 12.
  • the contact elements 10 are introduced into the housings 6, 8 by their front end 18 following the longitudinal direction of the contact elements.
  • the body has a relief projecting into the housing.
  • the lug 16 flexes on entering in its recess, then extends again after having exceeded the relief when the contact element arrives in limit switch and is installed in the housing.
  • the contact element is biased in a tight direction to bring it out of the housing, the lug comes into abutment against the relief to prevent the exit of the element of contact. This achieves the locking of the contact element.
  • the lamp holder also has two locks 20, 22 movable relative to the body 4 between a position open and a closed position, associated with the elements of respective contact 10.
  • the lock 20 on the right is shown on the left in the open position and the latch 22 in the closed position.
  • the locks are integrated into recesses flare part 5 so they seem to be formed by cutting the flared part.
  • the locks are then opposed to each other to the two ends furthest from the flared part.
  • Each lock is connected to the body 4 by means of a hinge 26 orthogonal to the longitudinal direction contact elements and housings.
  • the hinges are adjacent to the junction of the flared part 5 and of the cylindrical part 3.
  • the locks are molded in one piece with the body 4, the hinges being formed by a local thinning of the wall of the body.
  • Each lock 20, 22 has a flat wall 28 extending in the closed position at the end of the part flared 5 opposite to the cylindrical part 3 being perpendicular to the direction of introduction of contact elements 10 in the housings.
  • a free edge of this wall which is adjacent to the conductor and to the crimping in closed position, has a notch in look of the conductor and crimping so that the wall does not abut against them.
  • Each lock 20, 22 has four ribs 30 parallel to the direction of introduction of the elements of contact 10 in housings 6, 8 and perpendicular to the planar wall 28 extending along the latter.
  • the two ribs 30 In closed position of the lock 20, 22, the two ribs 30 the most central of the succession come into contact by their edge opposite to the wall 28 with the edge of the narrowed end 12 of the contact element 10 installed in its housing 6, 8.
  • the two ribs 30 are in contact with the end 12 respectively of on both sides of the crimping (and of the conductor).
  • Each rib 30 extends on either side of the edge of the end 12, beyond it on both sides of the singing. In the closed position, these two ribs 30 thus extend in the exit trajectory of the end 12 of the contact element, being contiguous at this end. Locks form obstacle to the exit of the contact elements, and constitute a double lock.
  • each lock 20, 22 is tilted around its hinge 26 towards the outside of the flared part 5 and extends out of the trajectory of the contact element, as shown in the section left of figure 1. It thus authorizes the introduction of the contact element in the housing. Locks 20, 22 are molded in the open position.
  • Each lock has tabs 32 extending projecting from the side faces of the lock in plan view. When switching the lock from the open position to the closed position, the legs forcefully cross a narrowing of the cut of the flared part 5. These tabs constitute latching means allowing immobilize the locks 20, 22 on the body 4 in closed position.
  • the latches 20, 22 can be closed and immobilized.
  • the ability to close the locks thus guarantees correct mounting of the contact. Also, if the locks are not closed, the abnormal size of the flared part 5 of the lamp holder makes it unsuitable for installation in the projector, as shown on the left side of the Figure 1 on which the volume of the reflector has been indicated in dotted lines.
  • Figure 4 shows a second mode of realization of the invention.
  • the part cylindrical of the body 4 is open and divided according to a common median longitudinal plane of the housings 6, 8 for delimit a body part defining a lock single 40 in the form of a flap.
  • Housing has hollow the same shape as the contact elements. They are defined half in this body and half in the lock wall.
  • the lock is movable by rotation by relation to the body by means of a hinge 43 parallel to the longitudinal direction of the contact elements and housing.
  • the closed position of the lock corresponds to the position of the lock in contact with the body being folded over the body according to the above-mentioned common plane.
  • the dwellings are then closed by the union of their two halves.
  • a free longitudinal edge of the flap has snap tabs 41 engaging a corresponding edge of the body to immobilize the flap in closed position on the body.
  • the open position is where the flap is tilted away from the body, the housings being open and their halves being distant one from the other, as in figure 4.
  • the elements of contact are arranged in the housings by placing the contact elements in the body half-housings following a lateral trajectory, then closing the lock. This embodiment facilitates installation contact elements in the accommodation.
  • the body 4 and the latch 40 have elongated recesses 42 adjacent to the end upper housing halves and opening into these. These recesses extend over the body in the flared part to a free end thereof. These recesses receive the fixed conductors 14 to the contact elements when the contact elements are arranged in the housings.
  • the operation of the lamp holder is analogous to that of the previous mode. So if the elements of contact are properly installed in their housing, it is possible to close the shutter and immobilize it on the body. If the contact elements are not installed correctly, it is not possible to close the flap and it cannot be immobilized on the body. Of more, if the lock is not closed, the space abnormal of the cylindrical part of the lamp holder makes it not suitable for installation in the projector.
  • the hinges can be parallel to the direction longitudinal of the contact elements.
  • the lamp holder may include a single contact element, for example, if the lamp is connected to ground by sound pellet.
