Description

The invention relates to a device for electrical contacting of lamps in headlamps according to the preamble of claim 1.

From the DE 198 16 364 C2 a lamp housing is known, which serves to receive a luminous body, a transparent cover in the form of a protective disk or a lens disc and a reflector. As lamps or luminous bodies are burners or lamps, preferably single-ended discharge lamps, in a vertical or horizontal mounting position, that is, in each case perpendicular to the optical axis, or in the axial installation position, that is, in the optical axis used.

The lamps have a gas-filled glass body with electrodes arranged therein, a lamp cap through which the supply lines are led to the electrodes, and two or more contact pins which are arranged on the end of the lamp cap opposite the glass body. The contact pins are inserted for connection to a voltage source in the sockets of a lamp socket connected to the lamp housing, with a close fit between the sockets and the contact pins for the high current levels of the lamp current to be transmitted is necessary.

At the same time, the contact pins serve, for example, discharge lamps which are socketed on one side as fastening means for the discharge lamp. As with increasing lamp power and the size of the discharge lamps and in particular the length of the glass body and the lamp base increases, the lamps at larger lamp power on such a size that especially in a horizontal mounting position of the discharge lamps considerable forces acting on the addition to the power supply as mounting contacts Contact pins are exercised.

These forces lead to a deterioration of the contact between the pins and the sockets of the lamp socket, resulting in an increased contact resistance in the transmission of the lamp current, a displacement of the lamp from the focus of the reflector and thereby a reduced light output and with a transfer of forces in the lamp interior is connected, which can lead to inadmissible voltages and eventually to failure of the lamp.

However, the disadvantages of the exclusive storage of the lamp via the contact pins affect not only the static range on the size of the lamp, but especially in the dynamic range when transporting a headlamp or its operation with jerky pivoting movements, shocks on the lamp housing and the like.

In order to use a lamp housing for lamps with different lamp base diameters without replacement of a recording device and to use the pins of the lamps exclusively for the transmission of the lamp current can, in which consists of the DE 198 16 364 C2 known lamp housing, the receiving device of clamping jaws which engage around the lamp base and by means of the adjusting device in an open position in which the lamp cap is released, and in a locking position in which the lamp cap is fixed, are adjustable. The adjusting device consists of a pawl with two geometrically identically shaped inclined surfaces which rest on the upper and lower clamping jaw in such a way that when an adjustment of the pawl, the clamping jaws are radially spread.

When you press the adjustment for opening and closing the jaws takes place at the same time an opening and closing of the contact pins of the bulb receiving sockets, so that easily removed by releasing the lamp socket by simultaneous release of the contact pins upon actuation of the adjusting device for opening and closing the jaws, the light source can be used in the open position of the lamp holder a light source.

Usually, the lamp or bulb holders, depending on the power of the headlamp for receiving one of these power corresponding light source, d. H. designed a lamp or a burner predetermined power consumption and / or power output. If a light source of different power is to be used for a wide range of power independent use of the headlamp housing, this fails because of the different distances and diameters of the contact pins of the bulbs, which usually because of the different power consumption of bulbs of different power and mechanical-constructive reasons of the bulbs increasing power of the bulbs increase. This makes the replacement of not only the bulb holder, but also the entire lamp holder receiving and required associated with the lamp holder when using a headlight housing, although the bulb holder is able to accommodate lamps or burners with different dimensions, in particular the bulb socket.

Object of the present invention is to provide a device for electrical contacting of bulbs in headlamps that receives bulbs of different power, without replacement of the lamp holder or the bulb holder is required.

This object is achieved by the features of claim 1.

The solution according to the invention allows the inclusion of bulbs of different power in a headlamp, without replacement of the lamp holder or the bulb holder is required.

The solution according to the invention is based on the idea of creating the preconditions for inserting a headlight housing for different power levels by plug-in socket pairs for different light sources in the light-emitting means socket. without an exchange of individual elements of the headlight, in particular the bulb holder or the lamp holder, is required.

Accordingly, according to a further feature of the invention, the sockets of the receptacle pairs have different distances from each other and / or diameter.

For centering of the lamp socket pairs or sockets are arranged so that the center of the lamp is disposed above the central axis of the lamp holder, so that according to a further feature of the invention, the pairs of sockets are arranged symmetrically to the axes of symmetry of the lamp holder.

If the luminous spot of the luminous means is not located in the center of the luminous means, then in an alternative embodiment the pairs of receptacles can be offset relative to one another with respect to at least one axis of symmetry of the illuminant mount.

For receiving lamp sockets bulbs of different power, the pins are so spaced and have a diameter such that the different pairs of sockets would overlap, according to a further feature of the invention, the socket pairs with respect to at least one axis of symmetry of the lamp holder can be arranged separately or staggered and, if necessary, at least partially merge into each other, so that increases for bulbs of different power and / or power output of the distance and / or the diameter of the sockets with increasing power consumption and / or power output of the lighting means.

To allow a more compact design, the sockets are not arranged in the transverse axis of the bulb socket, but rotated to the transverse axis, so that the connecting lines of the socket pairs include different angles to an axis of symmetry of the socket.

In a preferred embodiment of the invention, the sockets are formed from female connector parts which are arranged in clamping pieces whose opposing connecting surfaces for receiving the contact pins of the Illuminant removed from each other and for making electrical contact with the contact pins of the lamp can be guided each other.

This embodiment of the invention allows on the one hand a simple coupling in the contacting of the sockets with the pins of a lamp with a mechanism for opening and closing jaws for receiving a bulb socket to relieve the electrical contacts and on the other hand, the design and arrangement of a variety of pairs of sockets for different bulbs performance. The shape and cross-sections or diameter of the sockets and distances of the socket pairs may vary as desired, without constructive problems in the arrangement of the socket pairs occur or bulbs outside the axis of symmetry of the light-emitting and thus for example outside the axis of symmetry of a reflector must be arranged. At the same time optimum contact of the sockets and the contact pins of the lamp is ensured, which is largely independent of tolerances, since the clamping pieces are joined, for example under spring preload corresponding to the diameter or cross-sectional shape of the contact pins of the lamp and / or the required clamping force.

By a symmetrical or asymmetrical design of the female connector parts on the opposing connecting surfaces of the clamping pieces, the opening and closing of a lamp holder with the opening and closing of the electrical connection of the sockets or receptacle pairs and the contact pins of the lamp can be combined, so that when the lamp holder of the lamp socket inserted into the lamp holder and the pins in the bulb socket and performed by pressing the connector both the position assurance and the electrical contact of the bulb.

The female connector parts may be formed both symmetrically and asymmetrically with respect to the connecting surfaces of the clamping pieces. In the same way, the female connector parts can be semi-cylindrical or polygonal, in particular four and hexagonal shaped.

The various sockets can either merge into each other or be formed as a single, separate sockets and sockets pairs. there the socket pairs can be arranged offset from each other in dependence on the distance of the pins and their diameter and thus in dependence on the distance of the socket pairs and their diameter.

When pair of sockets, which are arranged in relation to their diameter closer to each other, the interface between the clamping pieces can also be angled or bent, so that even with a limited size of the bulb socket sockets or sockets pairs can be provided for different bulbs. In angled or bowed sockets or receptacle pairs, the receptacle parts are formed to give the desired cross-section when assembled, i. in, for example, semicircular female connector parts adjacent the parting line sections are flattened, so that the female parts do not catch when merging the clamping pieces.

For the arrangement of sockets or pairs of sockets at an even smaller distance at the same time enlarged diameter, i. for an even more compact design of the lamp holder, the arrangement of one or more passive intermediate clamping pieces is provided according to a further feature of the invention, so that even with a small size of the lamp holder, the arrangement of a plurality of sockets or socket pairs is possible.

Both with an arrangement of two clamping pieces as well as with an arrangement of two clamping pieces and one or more intermediate clamping pieces sockets or socket pairs can be provided for more than two bulbs.

An advantageous embodiment of the solution according to the invention is characterized in that the clamping pieces or intermediate clamping pieces are designed as metal jaws.

For electrical separation of the sockets, the clamping pieces and intermediate clamping pieces have a substantially perpendicular to the dividing line or to the connecting surfaces extending insulation, either as a distance or as an insulating layer between the sockets of a pole containing Teilklemmstücken or Zwischen-Teilklemmstücken and the Sockets of the is arranged other pole containing Teilklemmstücken or Zwischen-Teilklemmstücken.

Preferably, the Teilklemmstücke or intermediate-Teilklemmstücke at their opposite ends of the sockets are hinged together, so that they form a U-shaped socket, at the ends of the sockets are arranged.

To form a defined clamping force of the Teilklemmstücke or intermediate Teilklemmstücke these are preferably resiliently biased in the joining direction.

An advantageous embodiment of the solution according to the invention is characterized by a modular design with a universal frame, which is provided for a particular bulb holder, and then inserts for different sized bulbs can be inserted, the inserts of a combination of preferably metallic clamping pieces and preferably ceramic Support and filling materials exist.

The universal frame frame preferably consists of a fixed and a movable part, wherein the movable part allows the pressing or clamping of the clamping pieces. The force is either directly absorbed by specially designed clamps or transmitted by stamp on the clamping pieces. The main advantage of this modular design is the possibility to exchange all parts lying within the insert.

Accordingly, the bulb socket on a frame, in which different, interchangeable socket inserts are used, which contain the clamping pieces and at least partially disposed between the clamping pieces and the frame frame support elements.

The fixed and movable frame parts of the frame frame is assigned a Teilklemmstück in each case, wherein the movable frame parts are operatively connected to the Teilklemmstücken.

According to a further feature of the invention, the lamp inserts can be designed so that they are rotatable by 180 °, for example, another Distance of the sockets or different socket diameter to adjust.

This further solution can also be used to turn out corroded, for example, internal sockets to the outside, so that always electrically correct contact sockets on the inside, i. on the adjacent surfaces of the first and second Teilklemmstücke are arranged.

Fig. 1 shows in a perspective view of a spring-loaded bearing with a non-illustrated light source housing for a headlight Connected socket carrier 1, which receives a bulb holder 2 with sockets 7, 8 for power supply, in which the contact pins of a light source, such as a lamp or a burner, in particular a discharge lamp, are used.

The illuminant, not shown, has an elongated, gas-filled glass body, a luminous means base and contact pins for connection to the sockets 8, 9 of the luminous means holder 2. Due to the length of the glass body and its weight and the weight of the bulb socket of the bulb act without an additional receiving device on the pins of the bulb, via which the bulb is connected to the bulb holder 2 and thus via the socket carrier 1 with the bulb housing, considerable forces, in particular dynamic forces in the event of a sudden change in direction of the lamp housing or on the lamp housing or the headlamp acting shocks and the like, a. Since these forces are transmitted both into the bulb inside and there can lead to excessive voltages and failure of the bulb, as well as affect the electrical contact between the pins and the sockets 8, 9, the lamp power is reduced and there is a risk of premature failure of the bulb.

To reduce or eliminate the forces acting on the pins and for improved support and clamping of the bulb, a receiving device in the form of two jaws 3, 4 is provided, which comprise the bulb socket axially spaced apart and clamp force and / or positive fit.

The upper jaw 3 and the lower jaw 4 are each connected to two lever arms 31, 32 and 41, 42, which are connected to their jaws 3, 4 opposite ends via transverse webs together and rest flat against the light-emitting socket 2. Parallel to the transverse webs connecting rods between the lever arms 31, 32 and 41, 42 of the upper and lower clamping jaw 3, 4 are provided, which are connected via resilient supports with the socket carrier 1.

Due to the resilient mounting of the lever arms 31, 32 and 41, 42 and thus of the jaws 3, 4 is caused in an example, by shocks Illuminating movement moves the receiving device in the same plane, so that the contact pins of the bulb remain free of tension. By also elastic support of the bulb holder 2 via a spring bearing relative to the socket carrier 1 ensures that no forces are transmitted to the pins of the bulb, so that the pins are used for the exclusive transmission of electrical power.

The upper and lower clamping jaws 3, 4 have a trapezoidal cut-out, so that in the clamping state of the lighting means, the individual sides of the trapezoidal cut-outs bear a point contact on the usually cylindrical illuminant base.

For adjusting the jaws 3, 4 of an open position in which the bulb socket is released to remove the bulb, in a closed or locking position in which the jaws 3, 4 clamp the bulb socket and fix the bulb in its position, serves an adjustment 5 with an adjusting member 51, 52 acting on the lever arms 31, 32, or 41, 42 and an actuating member 50 for manual actuation of the adjusting device 5.

The adjustment consists - as in particular the front view according to Fig. 2 can be seen - from both sides of the lever arms 31, 32, and 41, 42 arranged ellipsoidal disks 51, 52, whose peripheral edge with bronze bearings 34, 35 and 44, 45 cooperates. The large axis of the ellipsoidal disk 51, 52 between the two bronze bearings 34, 44 and 35, 45, so the lever arms 31, 32 and 41, 42 and thus the upper and lower jaw 3, 4 for removal or Replacing the bulb in the open position moved apart. If, however, the small axis of the ellipsoidal disk 51, 52 between the two bronze bearings 34, 44 and 35, 45, the lever arms 31, 32 and 41, 42 and thus the upper and lower jaw 3, 4 for power and positive locking system at the bulb socket in the closed or locked position merged.

The actuator consists of a guided through the center of the ellipsoidal disks 51, 52 and by the bulb holder 2 adjustment axis 50, which is connected in a manner not shown outside of the headlight housing with an adjusting lever or an adjustment knob for manual actuation of the adjustment.

The front view according to Fig. 2 are the double sockets 9, 9 'for receiving the contact pins of a light source for the power supply, which are suitable for light sources with contact pins of different dimensions and distances and thus generally different light output. Thus, the contact pins of a 12 kW discharge lamp in the smaller spaced apart having sockets 93, 94 of the double sockets 9, 9 'are used while the contact pins of a 18 kW discharge lamp in the farther apart sockets 91, 92 of the double -Socket 9, 9 'are inserted.

In the Fig. 3 to 10 various configurations for the formation of sockets or sockets pairs of female connector parts are shown by a translational or rotational merging two clamping pieces 6, 7 in the direction of the Fig. 3 to 10 plotted arrows S closed and by passing apart of the clamping pieces 6, 7 in the direction of the Fig. 3 to 10 opened arrows O are opened. In each case the same geometry of the socket parts show the Fig. 3 . 5 . 7 and 9 the formation of sockets or socket pairs by linear, translational merging of the clamping pieces 6, 7, while in the Fig. 4 . 6 . 8th and 10 the formation of sockets or socket pairs by pivoting, that is, by rotation of the clamping pieces 6, 7 are formed by predetermined articulation points.

In the embodiment according to the FIGS. 9 and 10 In addition, a passive intermediate clamping piece 8 between the clamping pieces 6, 7 is provided that the respective sockets or socket pairs 91 to 94 with the mutual clamping pieces 6, 7 forms.

The clamping pieces 6, 7 are divided into first and second or upper and lower or right and left Teilklemmstücke 61, 62 and 71, 72 depending on the opening and closing direction of the Teilklemmstücke 61, 62 and 71, 72 and the respective poles for assigned to the power supply of the illuminant to be inserted in the bulb holder and connected thereto. The clamping pieces 6, 7 are preferably made of metal jaws, wherein between the upper and lower Teilklemmstück 61, 62 or 71, 72 and Zwischen-Teilklemmstück 81, 82 either a sufficient distance to the potential separation or an insulating layer 60, 70, 80 is provided. At the mutually facing connecting surfaces 10 of the clamping pieces 6, 7 or part clamping pieces 61, 62 and 71, 72 and the mutually facing connecting surfaces 12, 13 of the Clamps 6, 7 or Teilklemmstücke 61, 62 and 71, 72 and the intermediate clamping piece 8 or the intermediate-Teilklemmstücke 81, 82 are socket parts in the form of round or semi-cylindrical recesses provided in the direction of the arrow when merging the clamping pieces 6, 7 S form two pairs of sockets 91 to 94.

In the embodiment according to Fig. 3 are formed by the merger of the clamping pieces 6, 7 two pairs of sockets 91, 92 and 93, 94, of which the outer pair of sockets 91, 92 has a larger diameter than the inner pair of sockets 93, 94 and the distance between the two sockets 91, 92nd or 93, 94 is dimensioned so that the inner pair of socket sockets 93, 94 is disposed completely within the outer pair of sockets 91, 92. The pairs of sockets 91, 92 and 93, 94 are combined to close the contacts as far as the diameter and / or the cross-sectional shape of the contact pins of the lamp or the required clamping force require.

In Fig. 4 an embodiment is shown in which the part clamping pieces 62, 71 about pivot points 63, 73 are pivotable, while the other part clamping pieces 61, 72 have bevelled surfaces, so that the part clamping pieces 62, 71 by pivoting about the pivot points 63, 73 in the direction of Arrow O can be opened and closed in the direction of the arrow S to form the socket pairs 91, 92 and 93, 94.

If the diameter of the contact pins of the luminous means to be accommodated increases in relation to their distance, the embodiments according to FIGS Fig. 5 to 10 also the inclusion of various such bulbs, wherein in the illustrated embodiments, two pairs of sockets 91, 92 and 93, 94 are shown, but according to the same principle also further pairs of sockets can be provided.

In the embodiments according to the FIGS. 5 and 6 go the receptacle pairs 91, 92 and 93, 94 partially into each other and are used to hold contact pins of different bulbs whose distance at the same diameter as in the bulb holder according to 3 and 4 is lower. Despite the partially merging sockets 91, 93 and 92, 94 is a sufficiently firm contact the sockets 91, 92 and 93, 94 ensured with the contact pins of the various bulbs, since the contact pins are covered by more than half of the sockets 91 to 94.

Also in this variant of the solution according to the invention shows Fig. 5 a translational adjustment of the clamping pieces 6, 7, while in Fig. 6 a rotation of the part clamping pieces 62, 71 about pivot points 63, 73 for opening and closing of the sockets or socket pairs 91 to 94 is shown.

Alternatively to the arrangement of the sockets or sockets pairs 91 to 94 according to the FIGS. 5 and 6 can the dividing line or connecting surface 11 between the clamping pieces 6, 7 according to the FIGS. 7 and 8 also be angled or bent, so that with slight increase in the width of the clamping pieces 6, 7 a plurality of socket pairs 91, 92 and 93, 94 can be formed without these merge into one another.

In the arrangement according to the FIGS. 7 and 8 Further space for the arrangement of additional pairs of sockets can be created by partial overlapping of sockets or sockets 91 to 94, so that a light-emitting means for receiving more than two different light sources is formed. An alternative embodiment or means for receiving further sockets would be a broadening of the clamping pieces 6, 7th

In this arrangement shows Fig. 7 a translational adjustment of the clamping pieces 6, 7, while in Fig. 8 a rotation of the part clamping pieces 62, 71 about pivot points 63, 73 for opening and closing of the sockets or socket pairs 91 to 94 is shown.

The female parts of the angle or arc to each other arranged sockets or sockets 91 to 94 are formed so that they Assembling the desired cross-section result, ie, for example, semicircular female connector parts adjacent to the dividing line sections 910, 911 of the sockets 91, 92 and 930 of the sockets 93, 94 flattened so that the female parts do not catch when merging the clamping pieces. The dividing line adjacent sections 931 of the sockets 93, 94, however, are aligned with each other, since they are aligned perpendicular to the parting line. Accordingly, the flattening increases with increasing distance from the vertical parting line, resulting in Fig. 7 is indicated by the different imaginary tangential extensions of sections 910, 911 and 930 shown in dashed lines.

Upon further reduction of the distance of the contact pins in relation to their diameter is an arrangement according to the FIGS. 9 and 10 expedient in which the female parts in relation to their diameter narrower than in the above-described Fig. 3 to 8 are arranged or intended to form further sockets or receptacle pairs for contact pins with different spacing and diameter and are suitable.
