  The present invention relates to a light source module.

  2. Description of the Related Art As a light source module, there is known a light source module in which a laser package as a light emitting component is arranged on a metal heat dissipation member (see Patent Document 1 below).

  In the light source module of Patent Document 1 below, the stem of the laser package is fixed to a metal heat radiating member, and the pin terminal of the laser package is inserted into the through hole of the wiring board to which the heat radiating member is fixed. A land is formed in the through hole of the wiring board, and the land and the pin terminal of the laser package are fixed by a connecting member such as solder and are electrically connected to each other.

Japanese Patent Application No. 2006-170905

  By the way, in the light source module of the said patent document 1, when the heat radiating member expand | swells due to the heat etc. which arise in a laser package, there exists a tendency for the force pulled in the longitudinal direction of the pin terminal with respect to the pin terminal of a laser package. When this pulling force acts on the pin terminal, there is a concern that stress is generated in the connecting member that fixes the pin and the land.

  Then, an object of this invention is to provide the light source module which can suppress the stress which arises in a connection part with a pin terminal.

  To achieve the above object, a light source module according to the present invention includes a heat radiating member, a light emitting component main body disposed on one opening side of a through hole penetrating the heat radiating member, and the through hole connected to the light emitting component main body. And a connector disposed on the other opening side of the through hole, the connector sandwiching the pin terminal protruding from the other opening of the through hole It has an elastic terminal piece to be connected with.

  According to such a light source module, the elastic terminal piece and the pin terminal are not fixed to each other, and the connection is maintained by the elastic force of the elastic terminal piece. For this reason, even if it is a case where force arises in a pin terminal so that it may be pulled in the longitudinal direction of a pin terminal, it can control that stress is applied to the connection part of a pin terminal and an elastic terminal piece. Furthermore, since the pin terminal and the elastic terminal piece are not fixed, even when the pin terminal vibrates along the longitudinal direction of the pin terminal, the connection with the pin terminal is maintained without restricting the vibration. To do. Therefore, compared with the case where a pin terminal and an elastic terminal piece are fixed, it can avoid applying excessive stress to the connection part of the said pin terminal and an elastic terminal piece. Thus, the light source module of the present invention can suppress the stress generated in the connection portion with the pin terminal.

  The connector has a resin frame surrounding the side of the elastic terminal piece, and the elastic terminal piece and the frame are separated when at least the pin terminal is not sandwiched. It is preferable.

  Since the elastic terminal piece and the frame material are separated from each other, even if the position where the pin terminal is inserted with respect to the elastic terminal piece is shifted to the frame material side, at least a part of the elastic terminal piece follows the shifted side. It will be elastically deformed. Thereafter, the elastic terminal piece is restored by the elastic force of the elastic terminal piece, so that the pin terminal can be sandwiched at a position before the pin terminal is inserted. That is, since the elastic terminal piece and the frame member are separated in a state where the pin terminal is not sandwiched between the elastic terminal pieces, the range in which the elastic terminal piece can center the pin terminal can be expanded.

  The connector includes a first connector portion having the elastic terminal piece and the frame member, a second connector portion into which an external connector can be inserted and removed, and a connection for connecting the first connector portion and the second connector portion. The connecting portion includes a bent portion bent in a first direction intersecting with a longitudinal direction of the pin terminal sandwiched between the elastic terminal pieces, and between the bent portion and the second connector portion. It is preferable that the connector and the heat radiating member are fixed by a screw screwed into the heat radiating member through the screw hole.

  In this case, a portion of the connecting portion that extends from the bent portion in the first direction different from the longitudinal direction of the pin end is a fixing position with the heat radiating member. For this reason, even if the external connector is inserted into the second connector portion extending in the first direction from the second direction opposite to the first direction, it is possible to prevent the connector from moving in the second direction. it can. Moreover, even if the external connector inserted into the second connector portion is pulled out along the first direction, the movement of the connector in the first direction can be suppressed. Therefore, the relative positional relationship between the elastic terminal piece of the first connector portion and the pin terminal sandwiched between the elastic terminal pieces can be maintained regardless of whether the external connector is inserted into or removed from the second connector portion. It is possible to suppress the stress generated in the connection portion with the terminal.

  As another aspect different from the light source module, the connector includes a first connector part having the elastic terminal piece and the frame member, a second connector part in which an external connector can be inserted and removed, and the first connector part. And a connecting portion that connects the second connector portion, and the connecting portion has a bent portion that is bent in a first direction intersecting with a longitudinal direction of the pin terminal sandwiched between the elastic terminal pieces. The heat radiating member preferably has a restricting member that restricts displacement of the connector in the first direction and a second direction opposite to the first direction.

  In this case, even if the external connector is inserted from the second direction into the second connector portion extending in the first direction different from the longitudinal direction of the pin terminal, the external connector inserted into the second connector portion is the first connector. Even if the connector is pulled out along the direction, the displacement of the connector is restricted by the wall portion. Therefore, the relative positional relationship between the elastic terminal piece of the first connector portion and the pin terminal sandwiched between the elastic terminal pieces can be maintained regardless of whether the external connector is inserted into or removed from the second connector portion. It is possible to suppress the stress generated in the connection portion with the terminal.

  The heat dissipation member having the wall portion includes a frame portion surrounding the frame material of the first connector portion, and an engagement portion provided on an inner surface side of the frame portion, and the first connector portion It is preferable that the engaging claw provided on the outer surface side of the frame member is engaged.

  In this case, the displacement of the first connector portion is restricted by the engagement between the frame portion of the heat dissipation member and the frame member of the first connector portion. Therefore, even if vibration or the like is applied to the light source module, it is possible to maintain the relative positional relationship between the elastic terminal piece and the pin terminal sandwiched between the elastic terminal pieces, which is further generated at the connection portion between the pin terminals. Stress can be suppressed.

  Moreover, it is preferable that the said frame part serves as the said limitation member. In this case, it is possible to reduce the size of the heat dissipation member as compared with the case where the frame portion and the wall portion are provided separately.

  In addition, the connecting portion in the other side surface has a screw hole provided between the bent portion and the second connector portion, and the connector and the heat radiating member communicate the heat dissipation via the screw hole. It is preferable to be fixed by a screw screwed into the member. In this case, the displacement of the connector can be further regulated.

  As described above, according to the present invention, it is possible to provide a light source module capable of suppressing stress generated in a connection portion with a pin terminal.

One end of the shade 63 is fixed to the base plate 20 so as to be located in the second focus or the vicinity of the second focus. The shade 63 is irradiated with a part of the light emitted from the light source module 30 and reflected by the reflector 61. Part of this light is shielded by the shade 63 and does not enter the projection lens 62, and the other part travels straight without being shielded by one end of the shade 63 or is reflected by one end of the shade 63. The light enters the projection lens 62. As a result, the light emitted from the projection lens 62 forms a light distribution that reflects the shape of one end of the shade 63.

  In the optical unit 60 of the present embodiment, as described above, the projection lens 62 is fixed to the base plate 20 via the lens holder 62D, and the shade 63 is fixed to the base plate 20.

In the optical unit 60 of the present embodiment, the reflector 61 and the light source module 30 are also fixed to the base plate 20 via the heat dissipation unit 50. For this reason, the relative positions of the light source module 30, the reflector 61, the shade 63, and the projection lens 62 are also accurately determined. Therefore, it is possible to accurately predict the optical path of the light emitted from the light source module 30 and entering the projection lens 62 via the shade 63. In the present embodiment, an example in which the shade 63 is fixed is shown, but the shade 63 may be movable, for example. In this case, the light distribution pattern can be changed by controlling the movement of the shade 63 by the light control unit 40, for example.

<Light source module 30>

It may be arranged. When such a light wavelength conversion member is disposed, it is possible to emit light emitted from the light emitting element and mixed color light by converted light from the light wavelength conversion member. Examples of the light wavelength conversion member include YAG (Yttrium Aluminum Garnet) phosphor.

  The pair of pin terminals 33 </ b> B are fixed to the stem 33 </ b> C while being insulated from the stem 33 </ b> C, and are inserted into the respective through holes 32 </ b> H provided in the heat dissipation member 32. An insulating member IE is provided between the through hole 32H of the heat dissipation member 32 and the pin terminal 33B. By this insulating member IE, a short circuit between the pin terminal 33B serving as the anode and the pin terminal 33B serving as the cathode via the heat radiation member 32 is suppressed. Thus, the light emitting component main body 33A is fixed on the mounting surface of the base portion 32A in the heat radiating member 32 by the heat radiating adhesive layer AD in a state where the respective pin terminals 33B are inserted into the through holes 32H. .

  FIG. 3 is a view showing the connector 34. As shown in FIGS. 2 and 3, the connector 34 includes a first connector portion 35, a second connector portion 36, and a connecting portion 37. The first connector part 35 is surrounded by the frame part 32B of the heat radiating member 32, and is arranged in the arrangement space CS surrounded by the base part 32A and the frame part 32B of the heat radiating member 32. The first connector portion 35 surrounds the pair of elastic terminal pieces 41 connected by sandwiching the pin terminal 33B protruding from the other opening of the through hole 32H of the heat radiating member 32 and the side of the pair of elastic terminal pieces 41.

  FIG. 4 is a diagram illustrating a state in which the pin terminal 33B is inserted into the elastic terminal piece 41 in a state where the insertion position of the pin terminal 33B is shifted. As described above, the elastic terminal piece 41 and the frame member 42 are separated in a state where they are not sandwiched between the first elastic terminal piece 41A and the second elastic terminal piece 41B of the elastic terminal piece 41.

  Therefore, when the pin terminal 33B is inserted in a state of being shifted from the center between the first elastic terminal piece 41A and the second elastic terminal piece 41B to the frame member 42 side, as shown in FIG. The elastic terminal piece 41 is elastically deformed so that at least a part of it follows. Thereafter, the elastic terminal piece 41 is restored by the elastic force of the elastic terminal piece 41, so that the pin terminal 33B can be sandwiched at a position before the pin terminal 33B is inserted, as shown in FIG. That is, the elastic terminal piece 41 and the frame member 42 are separated in a state where the pin terminal 33B is not sandwiched between the first elastic terminal piece 41A and the second elastic terminal piece 41B of the elastic terminal piece 41, The range in which the elastic terminal piece 41 can center the pin terminal 33B is widened.

  As shown in FIG. 2, in a state where the elastic terminal piece 41 sandwiches the pin terminal 33B, the elastic terminal piece 41 and the pin terminal 33B are not mechanically connected and are not fixed. The connection between the elastic terminal piece 41 and the pin terminal 33B is maintained by the elastic force.

  As shown in FIGS. 2 and 3, the second connector portion 36 is configured such that an external connector can be inserted and removed, and a pair of terminals 43 and a resin frame member 44 surrounding the pair of terminals 43. And have. The terminal 43 extends substantially straight. The direction in which the terminal 43 extends intersects with the longitudinal direction of the pin terminal 33B protruding from the other opening of the through hole 32H of the heat radiating member 32. In the present embodiment, the direction in which the terminal 43 extends and the longitudinal direction of the pin terminal 33B are orthogonal to each other. The terminal 43 and the frame member 44 are separated from each other even if an external connector is inserted into or removed from the second connector portion 36, and a gap is formed between the terminal 43 and the frame member 44.

  As shown in FIGS. 2 and 3, the connecting portion 37 is configured to connect the first connector portion 35 and the second connector portion 36, and covers the pair of conductive wires 45 and the conductive wires 45. And a resin housing 46. One end of the conductive wire 45 is connected to the other end of the cylindrical member 41 </ b> C of the elastic terminal piece 41 of the first connector portion 35, and the other end of the conductive wire 45 is connected to the terminal 43 of the second connector portion 36. In the present embodiment, the elastic terminal piece 41, the terminal 43, and the conductive wire 45 are configured by one conductive member, and one end portion of the conductive member exposed from the housing 46 is the elastic terminal piece 41 and is exposed from the housing 46. The other end portion of the conductive member is a terminal 43, and an intermediate portion between the one end and the other end is a conductive wire 45. The housing 46 is connected to the frame member 42 of the first connector portion 35, and the elastic terminal piece 41 exposed from the housing 46 is located in a space surrounded by the frame member 42 and the housing 46. The housing 46 is connected to the frame member 44 of the second connector portion 36, and the terminal 43 exposed from the housing 46 is located in a space surrounded by the frame member 44 and the housing 46. In the present embodiment, the housing 46, the frame member 42 of the first connector part 35, and the frame member 44 of the second connector part 36 are integrally formed.

  The connecting portion 37 has a bent portion BP that is bent in a first direction D1 that intersects with the longitudinal direction of the pin terminal 33B sandwiched between the elastic terminal pieces 41. Therefore, the conductive wire 45 and the housing 46 are bent in the first direction D1 at the bent portion BP. In the present embodiment, the first direction D1 is a direction orthogonal to the longitudinal direction of the pin terminal 33B sandwiched between the elastic terminal pieces 41. The housing 46 has a pair of screw fixing portions 47 shown in FIG. 3 between the bent portion BP and the second connector portion 36. In the present embodiment, the screw fixing portion 47 is a plate-like member that protrudes from the outer wall of the housing 46 along a direction substantially orthogonal to the first direction D1. The screw fixing portion 47 is formed with a screw hole 47H.

  FIG. 5 is a diagram illustrating a state in which the connector 34 and the heat dissipation member 32 are fixed by the screw SW. A screw receiving portion 32C protruding from the tip of the frame portion 32B of the heat radiating member 32 is fitted into the screw hole 47H. The screw receiving portion 32C is a regulating member that regulates the displacement of the connector 34 in the first direction D1 and the second direction D2 opposite to the first direction D1 when fitted in the screw hole 47H. . That is, it can be understood that the frame portion 32B of the heat radiating member 32 surrounding the frame member 42 of the first connector portion 35 also serves as a regulating member that regulates the displacement of the connector 34 in the first direction D1 and the second direction D2. . A screw SW having a screw head larger than the screw hole 47H is screwed into the screw receiving portion 32C fitted in the screw hole 47H. Thus, the connector 34 is fixed to the heat radiating member 32 by the screw SW.

  As described above, in the light source module 30 of this embodiment, the connector 34 has the elastic terminal piece 41 that sandwiches and connects the pin terminal 33 </ b> B protruding from the other opening of the through hole 32 </ b> H of the heat radiating member 32.

  For this reason, the elastic terminal piece 41 and the pin terminal 33B are not fixed to each other, and the connection is maintained by the elastic force of the elastic terminal piece 41. Therefore, even when a force is generated in the pin terminal 33B so as to be pulled in the longitudinal direction of the pin terminal 33B, it is possible to suppress the stress from being applied to the connection portion between the pin terminal 33B and the elastic terminal piece 41. In addition, since the pin terminal 33B and the elastic terminal piece 41 are not fixed, even if the pin terminal 33B vibrates along the longitudinal direction of the pin terminal 33B, the pin terminal 33B and the pin terminal 33B are not restricted. Stay connected. Therefore, compared to the case where the pin terminal 33B and the elastic terminal piece 41 are fixed, it is possible to avoid applying excessive stress to the connection portion between the pin terminal 33B and the elastic terminal piece 41. Thus, the light source module 30 of the present invention can suppress the stress generated in the connection portion with the pin terminal 33B.

  In the present embodiment, the connector 34 includes a resin frame member 42 that surrounds the side of the elastic terminal piece 41, and the elastic terminal piece 41 and the frame member 42 do not sandwich at least the pin terminal 33 </ b> B. Are separated.

  For this reason, when the pin terminal 33B is inserted into the elastic terminal piece 41, the elastic terminal piece 41 can be elastically deformed so as to spread toward the frame member 42 side. Therefore, even if the position where the pin terminal 33B is inserted with respect to the elastic terminal piece 41 is shifted to the frame member 42 side, the elastic terminal piece 41 can sandwich the pin terminal 33B by elastic force. That is, the elastic terminal piece 41 and the frame member 42 are separated in a state where the pin terminal 33B is not sandwiched between the first elastic terminal piece 41A and the second elastic terminal piece 41B of the elastic terminal piece 41, The range that can be sandwiched by the gap between the elastic terminal piece 41 and the frame member 42 can be expanded.

  In the present embodiment, the connecting portion 37 of the connector 34 includes a bent portion BP bent in a first direction D1 intersecting with the longitudinal direction of the pin terminal 33B sandwiched between the elastic terminal pieces 41, and a second portion from the bent portion BP. And a screw hole 47H provided between the connector portion 36 and the connector portion 36. Further, the heat dissipation member 32 of the present embodiment has a screw receiving portion 32C that is fitted into the screw hole 47H. For this reason, the screw receiving portion 32C is fixed to a portion of the connecting portion 37 that extends from the bent portion BP in the first direction D1 different from the longitudinal direction of the pin terminal 33B.

  Therefore, even if the external connector is inserted from the second direction D2 into the second connector portion 36 extending in the first direction D1, the external connector inserted into the second connector portion 36 is moved along the first direction D1. Even if the connector is pulled out, the displacement of the connector is restricted by the screw receiving portion 32C. Thereby, in this embodiment, the relative positional relationship between the elastic terminal piece 41 of the first connector portion 35 and the pin terminal 33B sandwiched between the elastic terminal pieces 41, regardless of whether the external connector is inserted into or removed from the second connector portion 36. Is retained. As a result, the stress generated at the connection portion with the pin terminal can be further suppressed.

  Further, in the heat radiating member 32 of the present embodiment, the frame portion 32B of the heat radiating member 32 surrounding the frame member 42 of the first connector portion 35 also serves as the screw receiving portion 32C as a restricting member. The heat radiation member 32 can be downsized as compared with the case where the portion 32C is provided separately.

  Furthermore, in this embodiment, the connector 34 and the heat radiating member 32 are fixed by the screw SW screwed into the heat radiating member 32 through the screw hole 47H into which the screw receiving portion 32C is fitted.

  In this case, a portion of the connecting portion 37 that extends from the bent portion BP in the first direction D1 that is different from the longitudinal direction of the pin terminal 33B is a fixing position for the heat dissipation member 32. Accordingly, the relative positional relationship between the elastic terminal piece 41 of the first connector part 35 and the pin terminal 33B sandwiched between the elastic terminal pieces 41 is further maintained regardless of whether the external connector is inserted into or removed from the second connector part 36. be able to.

(2) 2nd Embodiment Next, the structure of a light source module is demonstrated using FIG. 5 as 2nd Embodiment. In addition, the same code | symbol is attached | subjected about the structure similar to the structure demonstrated above, and the overlapping description is abbreviate | omitted except the case where it demonstrates especially.

<Light source module 30X>
FIG. 6 is a cross-sectional view schematically showing the light source module 30X. As shown in FIG. 6, the light source module 30 </ b> X of the present embodiment is different from the first embodiment in that it includes a frame portion 32 </ b> X that is different from the frame portion 32 </ b> B of the heat dissipation member 32 in the first embodiment.

  Similarly to the frame portion 32B of the first embodiment, the frame portion 32X extends so as to protrude from the surface opposite to the mounting surface side of the base portion 32A, and the frame member 42 of the first connector portion 35. Surrounding. The thickness of the frame portion 32X of the present embodiment is thinner than the thickness of the frame portion 32B of the first embodiment, and the frame portion 32X is formed in a tubular shape. The thickness of the frame portion 32X is the length of the frame portion 32X in the direction parallel to the mounting surface of the base portion 32A.

  Moreover, the engaging part E1 is provided in the inner surface side of the frame part 32X of this embodiment. The first connector part 35 is supported by the heat radiating member 32 by engaging the engaging part E1 and the engaging claw E2 provided on the outer surface side of the frame member 42 of the first connector part 35.

  Further, a part of the frame portion 32X of the present embodiment is a wall portion that surrounds a portion of the connecting portion 37 that extends along the longitudinal direction of the pin terminal 33B sandwiched between the elastic terminal pieces 41 of the first connector portion 35. 32Xw. The wall portion 32Xw is a regulating member that regulates displacement of the connector 34 in the first direction D1 and the second direction D2. That is, it can be understood that the frame portion 32X surrounding the frame member 42 of the first connector portion 35 also serves as a restricting member that restricts displacement of the connector 34 in the first direction D1 and the second direction D2. However, the wall 32Xw may be provided separately from the frame 32X as long as the displacement of the connector 34 in the first direction D1 and the second direction D2 is restricted. When the wall portion 32Xw is provided separately from the frame portion 32X, the portion surrounding the part of the connecting portion 37 extending along the longitudinal direction of the pin terminal 33B sandwiched between the elastic terminal pieces 41 of the first connector portion 35 is the frame portion. Omitted from 32X. Therefore, when the wall portion 32Xw is provided separately from the frame portion 32X, the frame portion 32X surrounds only the frame material 42 of the first connector portion 35.

  In the present embodiment, the connector 34 and the heat radiating member 32 are not fixed by the screw SW as in the first embodiment. However, as in the first embodiment, the connector 34 and the heat radiating member 32 may be fixed by a screw SW, or may be fixed by another fixing tool other than the screw.

  As described above, in the light source module 30 </ b> X of the present embodiment, the heat dissipation member 32 has the frame part 32 </ b> X that surrounds the frame member 42 of the first connector part 35. The engaging portion E1 provided on the inner surface side of the frame portion 32X and the engaging claw E2 provided on the outer surface side of the frame member 42 of the first connector portion 35 are engaged.

  The displacement of the first connector portion 35 is restricted by the engagement between the frame portion 32X of the heat dissipation member 32 and the frame member 42 of the first connector portion. Therefore, even if vibration or the like is applied to the light source module, the relative positional relationship between the elastic terminal piece 41 and the pin terminal 33B sandwiched between the elastic terminal pieces 41 can be maintained, and the connection between the pin terminals is further increased. The stress generated in the portion can be suppressed.

  Moreover, the heat radiating member 32 of this embodiment has the wall part 32Xw which controls the displacement of the connector 34 to the 1st direction D1 and the 2nd direction D2.

  For this reason, even if an external connector is inserted from the second direction D2 into the second connector portion 36 extending in the first direction D1, the external connector inserted into the second connector portion 36 is moved along the first direction D1. Even if it is pulled out, the displacement of the connector is restricted by the frame portion 32X. Therefore, it is possible to maintain the relative positional relationship between the elastic terminal piece 41 of the first connector part 35 and the pin terminal 33B sandwiched between the elastic terminal pieces 41 regardless of whether the external connector is inserted into or removed from the second connector part 36. It is possible to further suppress the stress generated at the connecting portion between the pin terminals. In addition, when the connector 34 and the heat radiating member 32 are fixed with the screw SW as in the first embodiment, the displacement of the connector can be further regulated.

  Moreover, in the heat radiating member 32 of this embodiment, since the frame part 32X serves also as the wall part 32Xw as a control member, compared with the case where the frame part 32X and the wall part 32Xw are provided separately, the heat radiating member 32 is reduced in size. obtain.
