JP 2007-001334 A, FIG. 1 and FIG. Japanese Unexamined Patent Publication No. 2017-220431, FIGS. 1 and 14

  Miniaturization of automobile electrical components has been pursued, and miniaturization of in-vehicle cameras and harnesses has also been pursued. However, as the harness connector is miniaturized together with the harness, the arrangement interval of the connector terminals (11b) connected to the harness connector needs to be narrower. However, the arrangement interval on one end side of the connector terminal (11b) does not coincide with the arrangement interval of the connection chamber of the board side connector, so that it hits the housing of the board side connector and cannot be inserted into the connection chamber.

  One solution to this problem is to downsize the board-side connector in accordance with the arrangement interval of the connector terminals (11b) on one end side. However, when the board-side connector is a movable connector (see Patent Document 2 as an example), there is a reason why the size cannot be reduced as it is. That is, the movable connector includes a fixed housing that is mounted on the board, a movable housing that can be displaced in the three-dimensional directions of the X direction, the Y direction, and the Z direction with respect to the fixed housing. And a terminal having a U-shaped movable spring. The advantage of the movable connector is that the movable housing is displaced by the movable spring during fitting connection with the connection object, so that the displacement of the connection object to be inserted is absorbed, and the vibration and impact that occur when using electrical equipment. Can be absorbed by the displacement of the movable spring. When the board-side connector configured as such a movable connector is miniaturized in accordance with the narrowing of the pitch of the connector terminals (11b), the arrangement interval between adjacent connection chambers is reduced, and the connector terminals ( As for the mortar-shaped guide surface for attracting 11b), the spread in the XY direction is also reduced, and the amount of the connector terminal (11b) using the guide surface is reduced. As a result, the length that allows the displacement of the insertion position of the connector terminal with respect to the insertion axis of the connection chamber is shortened.

  In particular, in the case of a movable connector, the amount of guidance by the guide surface is the amount of displacement of the movable spring in the XY direction. Therefore, if the movable connector is downsized, the function of the movable spring to be displaced in the X-Y direction cannot be fully utilized, and the limit for absorbing the displacement accumulated by the assembly of the electric device by the displacement of the movable spring. The amount is limited to a small size.

  The present invention has been made against the background of the prior art as described above. The purpose is to increase the allowable displacement of the insertion position of the external connection terminal with respect to the connector of the imaging system while reducing the size of the external connection terminal and the external connection case holding the external connection terminal in accordance with the miniaturization of the external device. An object of the present invention is to provide an imaging device capable of performing the above.

  In order to achieve the above object, the present invention is configured as having the following features.

  The present invention relates to an imaging system connector having a connector terminal for transmitting an output signal generated by an imaging system and a connector housing for holding the connector terminal, and electrically connecting the connector terminal to transmit the output signal to an external device. For an imaging device including an external connection terminal and an external connection case that holds the external connection terminal, the external connection case has a guide protrusion that protrudes along a side surface of the connector housing, and the connector housing The guide protrusion when the external connection terminal is inserted into the connection chamber on the outer edge of the top surface portion facing the external connection case, and the connection chamber in which the external connection terminal is inserted and electrically connected to the connector terminal From the top surface to the side surface of the connector housing, and the external connection located away from the insertion port of the connection chamber. And having a mating guide surface to position the terminal in the insertion opening of the connecting chamber.

  According to the present invention, the external connection case has the guide protrusion protruding along the side surface of the connector housing. On the other hand, when the connector housing is inserted into the connection chamber of the connector housing at the outer edge of the top surface portion facing the external connection case, the guide guide surface receives the guide protrusion from the top surface portion to the side surface of the connector housing. have. For this reason, when the external connection case is fitted and connected to the imaging system housing to which the imaging system connector is attached, the external connection terminal positioned away from the connection chamber insertion port is positioned at the connection chamber insertion port. Can be made. Therefore, when the external connection case is fitted and connected to the housing of the imaging system, even if the external connection terminal is largely displaced in the direction intersecting the insertion direction with respect to the connection chamber, the positional deviation is corrected. The external connection terminal and the connector terminal can be electrically connected at the correct position. That is, even when the imaging device is downsized and the range of the insertion port is made smaller, for example, a sufficient amount of displacement (induction amount) in the crossing direction of the external connection terminals that are conductively connected to the connector terminals is ensured. be able to.

  With respect to the present invention, in the insertion direction in which the external connection terminal is inserted into the connection chamber, the guide protrusion and the fitting guide surface are arranged before the fitting, rather than between the external connection terminal and the top surface portion. It is also possible to make the distance between the two small.

  According to the present invention, before the external connection case is fitted and connected to the housing of the imaging system, the imaging device has the guide projection and the fitting guide surface between the external connection terminal and the top surface portion. The distance in the insertion direction is small. For this reason, when the external connection case is fitted and connected to the housing of the imaging system, the guide projection and the fitting guide surface can be brought into contact before the external connection terminal hits the top surface portion. Therefore, the shift in the crossing direction between the external connection terminal and the connection chamber can be more reliably corrected, and the external connection terminal and the connector terminal can be conductively connected at a correct position. At that time, since the guide protrusion and the fitting guide surface come into contact, the external connection terminal is inserted toward the connection chamber without hitting the top surface portion of the connector housing. Can be prevented from being damaged due to strong contact.

  In the present invention, the guide protrusion may be configured to be positioned in the insertion direction with respect to the external connection terminal.

  According to the present invention, the guide protrusion is positioned in the insertion direction with respect to the external connection terminal. For this reason, for example, when connecting and connecting the external connection case to the housing of the imaging system, it is possible to connect the external connection case without performing design and processing for raising the portion where the guide projection hits the top surface portion of the connector housing. The guide protrusion and the fitting guide surface can be brought into contact with each other before the terminal and the top surface portion abut against each other. Thus, since the positional relationship between the external connection terminal and the guide protrusion in the insertion direction is simply configured, the top surface portion of the connector housing can have a simple shape, for example, a flat surface. Since the external connection terminal is inserted toward the connection chamber without hitting the top surface portion of the connector housing, it is possible to prevent the external connection terminal and the connector housing from being in strong contact and being damaged.

  The guide protrusion has an inclined portion tapered toward the tip, and the fitting guide surface may be configured to come into contact with the inclined portion when the external connection terminal is inserted into the connection chamber. it can.

  According to the present invention, the guide projection has the inclined portion, and the fitting guide surface is configured to contact the inclined portion. For this reason, when the external connection terminal is inserted into the connection chamber of the connector housing, the guide protrusion can be smoothly received from the top surface portion to the side surface of the connector housing.

  The connector housing has a guide inclined surface that is inclined from the top surface portion of the connector housing extending in a direction intersecting the insertion direction and guides insertion of the external connection terminal into the connection chamber. And when inserting the said external connection terminal in the said connection chamber, the said external connection terminal can also be comprised so that the said external connection terminal may be located at least on the said guidance inclined surface.

  According to the present invention, when the connector housing has a guiding inclined surface at the insertion port and the external connection case is fitted and connected to the housing of the imaging system, the fitting guiding surface connects the external connection terminal. It is comprised so that it may be located in the guidance inclined surface which guides insertion in a chamber. For this reason, when the external connection case is fitted and connected to the housing of the imaging system, the external connection terminal can be smoothly inserted into the connection chamber.

  The external connection terminal includes a first external connection terminal and a second external connection terminal arranged along the intersecting direction, and the connection chamber is a first array arranged along the intersecting direction. A connection chamber and a second connection chamber, wherein the guide inclined surface is formed on the first guide inclined surface provided in the insertion port of the first connection chamber and the insertion port of the second connection chamber. The external connection case has a pair of guide protrusions positioned in the crossing direction across the external connection terminal, and the connector housing sandwiches the connection chamber And when the external connection terminal is inserted into the connection chamber, the first external connection terminal is the first external connection terminal when the external connection terminal is inserted into the connection chamber. When positioned outside the range of the guiding inclined surface, When one of the guide protrusions contacts one of the pair of fitting guide surfaces and the second external connection terminal is located outside the range of the second guide inclined surface, the pair of guides The other of the protrusions and the other of the pair of fitting guide surfaces may be in contact with each other so that the external connection terminal is positioned on the guide inclined surface.

  According to the present invention, when the external connection case is fitted and connected to the housing of the imaging system, the first external connection terminal is greatly crossed over the guide inclined surface with respect to the first connection chamber. Even if they are misaligned, the misalignment can be corrected, and the external connection terminal and the connector terminal can be electrically connected at the correct position. Similarly, even if the second external connection terminal is largely displaced in the crossing direction on the opposite side beyond the guiding inclined surface with respect to the second connection chamber, the positional deviation can be corrected, and the external connection terminal And the connector terminal can be fitted and connected at a correct position. That is, even if the imaging device is downsized and, for example, the distance between the first connection chamber and the second connection chamber is narrower, the displacement allowance in the crossing direction of the external connection terminals that are conductively connected to the connector terminals is allowed. A sufficient capacity (the amount of invitation) can be secured.

  The connector terminal has a leg portion connected to the board, and the fitting guide surface is formed to protrude outward in the intersecting direction from the leg portion, and corresponds to the leg portion. It can also be configured to have a recess that is missing inward in the direction.

  According to the present invention, even if the fitting guide surface is formed in a larger range in the crossing direction, the fitting guide surface is formed with a recess that allows the leg portion of the connector terminal to be visually recognized in the insertion direction. The joining state of the legs to the substrate can be confirmed by visual observation or image inspection. Therefore, it is possible to improve the reliability of the imaging device while sufficiently securing the allowable shift amount (induction amount) in the crossing direction of the external connection terminals that are conductively connected to the connector terminals.

  The imaging system connector has a fixed housing that is separate from the connector housing, the connector housing is disposed so as to be relatively movable with respect to the fixed housing, and the connector terminal is connected to the fixed housing. The connector housing may be configured to have an elastically deformable portion that supports the connector housing so as to be relatively movable.

  According to the present invention, since the imaging system connector is configured such that the connector housing is movable with respect to the fixed housing, the imaging system connector moves by itself when the external connection terminal is inserted. Can be absorbed. Furthermore, since the imaging connector has a floating structure, it absorbs external vibrations and shocks to a certain extent to prevent disconnection and damage, and to prevent stress concentration on the connector terminal mounting part and the conductive connection part. it can.

  According to the present invention, the connector housing can also be configured to have a protective portion that extends in the insertion direction from the fitting guide surface so as to cover the elastic deformation portion.

  According to the present invention, since the protection part is formed so as to cover the elastic deformation part, the operator's finger, external parts or the like unintentionally contact the elastic deformation part and the elastic deformation part is damaged. Can be prevented.

  According to the imaging apparatus of the present invention, the external connection terminal and the connector can be reduced by using the alignment structure formed by the guide protrusion of the external connection case and the fitting guide surface of the connector housing while downsizing the external device connected to the external connection terminal. The terminal can be securely connected. Furthermore, according to the image pickup apparatus of the present invention, the displacement of the insertion position of the external connection terminal can be absorbed even if the amount of the lead-in of the connector housing cannot be sufficiently secured, so that the connector housing can be reduced in size. .

As shown in FIG. 2, the imaging component case 21 is formed in a bottomed cylindrical shape. As shown in FIG. 2, the optical component 22 such as a lens unit is mounted so as to block a hole penetrating the bottom wall located on the lower side in the Z direction of the imaging component case 21 in the vertical direction. As shown in FIG. 2, the imaging component case 21 accommodates an imaging element 23, a substrate 24 a, an internal connector 25, a substrate 24 b and an imaging system connector 30 on the optical component 22 in order. Yes.

It has a function to do. The board | substrate 24a and the board | substrate 24b have various electric elements and circuit wiring. The internal connector 25 connects the substrate 24a and the substrate 24b. As shown in FIG. 2, the imaging system connector 30 is mounted on the upper surface in the Z direction of the substrate 24b. The image pickup device 23, the substrate 24a, the internal connector 25, the substrate 24b, and the image pickup system connector 30 may be collectively referred to as an image pickup component.

Imaging system connector 30

  The imaging system connector 30 includes a connector terminal 33 that transmits an output signal generated by the “imaging system” and a “connector housing” that holds the connector terminal 33. The imaging system connector 30 connects an imaging component to an external device via the pin terminal 12. The imaging system connector 30 is rigidly connected to the board 24b, and the imaging system connector 30 connected to the board 24b has a pitch direction (X direction), an inter-row direction (Y direction), and a fitting direction. A configuration that is not movable in any of (Z direction) may be used.

  On the other hand, the imaging system connector 30 connected to the substrate 24b is movable in at least one of the pitch direction, the inter-column direction, and the fitting direction, and the imaging system connector 30 is configured as a movable (floating) connector that absorbs the fitting displacement. You can also That is, the imaging system connector 30 of the present embodiment includes a fixed housing 31, a movable housing 32 as a "connector housing", a plurality of connector terminals 33, and a fixing bracket 34, as shown in FIGS.

For example, in the substrate 24b, a positional deviation g is generated on the left side in the Y direction indicated by the solid line from the designed assembly position indicated by the two-dot chain line in FIGS.

  However, since the imaging system connector 30 is configured such that the movable housing 32 is movable with respect to the fixed housing 31, the imaging system connector 30 moves by itself when the pin terminal 12 is inserted. Can be absorbed. As shown in FIG. 8, when the external connection case 11 is fitted to the imaging component case 21 and the pin terminal 12 is inserted into the imaging system connector 30, the camera module 1 deforms the connector terminal 33. This displacement is absorbed by the movable housing 32 being displaced with respect to the fixed housing 31. As a result, the board 24b and the imaging system connector 30 are displaced with respect to the imaging component case 21, but the pin terminal 12 is correctly inserted into the imaging system connector 30 and externally connected to the imaging component case 21. Case 11 is fitted.

  Since the imaging connector 30 has a floating structure, it absorbs vibrations and shocks from the outside to some extent to prevent disconnection and damage, and concentrates stress on the connector terminal 33 mounting portion and the conductive connection portion. It also has a function to prevent.

  The movable housing 32 has a lower part 32 b formed in a rectangular parallelepiped shape along the peripheral wall 31 a of the fixed housing 31. And the movable housing 32 has the upper part 32c spreading in the shape of a shade, and is formed in the T shape by the front view and the side view. That is, in the side surface 32a of the movable housing 32, the upper part 32c projects in the X direction and the Y direction from the rectangular parallelepiped lower part 32b, and the top surface part 32d has a larger area than the lower part 32b in the XY plane. Yes.

  The movable housing 32 has a connection chamber 35 into which the pin terminal 12 is inserted and is electrically connected to the connector terminal 33. The connection chamber 35 is provided in the same number as the number of pin terminals 12 in order to conduct and connect with the plurality of pin terminals 12 included in the external connection case 11. The movable housing 32 of the present embodiment is provided with a total of eight connection chambers 35 with four (four rows) along the X direction (width direction) and two (two rows) along the Y direction (depth direction). It has been. That is, the connection chamber 35 is formed symmetrically about the center line along the X direction (longitudinal direction) of the movable housing 32.

  The connection chamber 35 into which the first pin terminal 13 is inserted corresponds to the first connection chamber 36, and the connection chamber 35 into which the second pin terminal 14 is inserted corresponds to the second connection chamber 37. doing.

  Each connection chamber 35 is formed through the movable housing 32 in the Z direction (height direction), has a quadrangular cross section in the XY direction (horizontal direction), and the side walls 38a and Y along the X direction. And a side wall 38b along the direction. A terminal fixing portion 38 c for press-fitting and fixing the other end side (movable housing fixing portion 33 d) of the connector terminal 33 is formed on the side wall 38 b of each connection chamber 35.

  In the connection chamber 35 penetrating the movable housing 32, an insertion port 39 that opens at the top surface portion 32 d of the movable housing 32 is formed. The movable housing 32 is configured such that the pin terminal 12 is inserted into the connection chamber 35 through the insertion port 39.

  The movable housing 32 is formed with a displacement restricting protrusion 32e that protrudes outward in the X direction (width direction) (see FIG. 3). The displacement restricting protrusion 32e has a function of restricting excessive displacement of the movable housing 32 by contacting the fixed housing 31 downward in the Y direction and the Z direction and contacting the fixed bracket 34 upward in the Z direction. ing.

Connector terminal 33

  The plurality of connector terminals 33 are formed by bending conductive metal pieces, and all have the same shape. Each connector terminal 33 includes a leg portion 33a, a fixed housing fixing portion 33b, an elastic deformation portion 33c, a movable housing fixing portion 33d, an elastic arm 33e, and a contact portion 33f. The leg portion 33a is a part that is connected to the substrate 24b and is soldered to the substrate 24b. The fixed housing fixing portion 33 b is press-fitted and fixed to the terminal fixing portion 31 d of the fixed housing 31. The elastic deformation portion 33c extends in an inverted U shape. The movable housing fixing portion 33d is press-fitted in the X-direction (plate width direction) and fixed to the terminal fixing portion 38c of the movable housing 32. The elastic arm 33e extends from the upper end of the movable housing fixing portion 33d. The contact portion 33f is formed at the tip of the elastic arm 33e and bent in a mountain shape.

  The elastic deformation portion 33c supports the movable housing 32 relative to the fixed housing 31 so as to be relatively movable in a three-dimensional direction combining the X direction (width direction), the Y direction (depth direction), and the Z direction (height direction). It is formed as a spring.

  The elastic arm 33e and the contact portion 33f are accommodated in the connection chamber 35, and are configured to be conductively connected by being pressed against the pin terminal 12 inserted into the connection chamber 35. That is, the pin terminal 12 inserted into the connection chamber 35 comes into press contact with the contact portion 33f, and the contact portion 33f contacts the pin terminal 12 with a predetermined contact pressure by the spring force (reaction force) of the elastic arm 33e against the press contact. By doing so, it is comprised so that favorable conduction | electrical_connection connection may be obtained.

Mating guide surface 40

  The movable housing 32 has a fitting guide surface 40 on the outer edge of the top surface portion 32 d facing the external connection case 11. When the pin terminal 12 is inserted into the connection chamber 35, the fitting guide surface 40 receives the guide protrusion 15 from the top surface portion 32 d to the side surface 32 a of the movable housing 32 and is positioned away from the insertion port 39 of the connection chamber 35. It has a function of positioning the pin terminal 12 at the insertion port 39 of the connection chamber 35.

  Therefore, when the external connection case 11 is fitted and connected to the imaging component case 21 including the imaging system connector 30, the pin terminal 12 positioned away from the insertion port 39 of the connection chamber 35 is inserted into the insertion port of the connection chamber 35. 39. Therefore, even when the external connection case 11 is fitted and connected to the imaging component case 21, even if the connection chamber 35 is largely displaced in the direction intersecting the direction in which the pin terminal 12 is inserted, Misalignment can be corrected. According to the camera module 1 of the present embodiment, the pin terminal 12 and the connector terminal 33 can be conductively connected at a correct position. That is, even if the camera module 1 is downsized and the range of the insertion port 39 is formed smaller, for example, the cross direction of the pin terminal 12 that is conductively connected to the connector terminal 33, for example, as shown in FIG. It is possible to ensure a sufficient amount of deviation (direction amount) in the direction.

  In the present embodiment, the camera module 1 is inserted such that the pin terminal 12 is inserted into the connection chamber 35 before the external connection case 11 is fitted and connected to the imaging component case 21 as shown in FIG. In the Z direction, which is the direction, the distance d2 between the guide protrusion 15 and the fitting guide surface 40 is smaller than the distance d1 between the pin terminal 12 and the top surface portion 32d.

  Therefore, when the external connection case 11 is fitted and connected to the imaging component case 21, the guide protrusion 15 and the fitting guide surface 40 can be brought into contact before the pin terminal 12 and the top surface portion 32d come into contact with each other. . Therefore, according to the camera module 1, it is possible to more reliably correct the shift in the crossing direction with respect to the insertion direction of the pin terminal 12 and the connection chamber 35, and the pin terminal 12 and the connector terminal 33 are conductively connected at a correct position. be able to. At that time, the guide protrusion 15 and the fitting guide surface 40 come into contact with each other, so that the pin terminal 12 is inserted toward the connection chamber 35 without hitting the top surface portion 32 d of the movable housing 32. For this reason, it is possible to prevent the pin terminal 12 and the movable housing 32 from being damaged due to strong contact or rubbing.

  Here, in order to bring the guide projection 15 and the fitting guide surface 40 into contact before the pin terminal 12 and the top surface portion 32d contact each other, for example, the top surface portion 32d is moved in the Z direction in the vicinity of the end portion in the crossing direction of the movable housing 32 It can also be configured to project upward. However, with this configuration, the imaging system connector 30 does not have a simple shape.

  On the other hand, in this embodiment, the guide protrusion 15 is located below the pin terminal 12 in the Z direction, which is the insertion direction. For this reason, for example, when the external connection case 11 is fitted and connected to the imaging component case 21 without performing a design and processing for raising the portion of the top surface portion 32d of the movable housing 32 where the guide protrusion 15 hits. The guide protrusion 15 and the fitting guide surface 40 can be brought into contact with each other before the pin terminal 12 and the top surface portion 32d contact each other. Thus, since the positional relationship in the insertion direction between the pin terminal 12 and the guide protrusion 15 is simply configured, the top surface portion 32d of the movable housing 32 can have a simple shape, for example, a flat surface. Since the pin terminal 12 is inserted toward the connection chamber 35 without hitting the top surface portion 32d of the movable housing 32, the pin terminal 12 and the movable housing 32 are in strong contact with each other or rubbed. It can be prevented from being damaged.

  The fitting guide surface 40 is formed as an inclined surface that skews between the top surface portion 32d and the side surface 32a. For example, as shown in FIG. 3 and the like, the fitting guide surface 40 has a flat surface in which a corner portion between the top surface portion 32d and the side surface 32a is missing in a 45 ° chamfer (C chamfer) shape, extending in the X direction. And the fitting guide surface 40 is comprised so that the inclination part 15a of the guide protrusion 15 may be contacted.

  Such a camera module 1 has the fitting guide surface 40 and the inclined portion 15a, so that the component force when the fitting guide surface 40 and the inclined portion 15a are moved relative to each other in the Z direction is in the Y direction. Function to occur. When the guide projection 15 is relatively moved downward in the Z direction with respect to the top surface portion 32d of the movable housing 32 of the imaging system connector 30, the guide projection 15 is more in the Y direction than the side surface 32a of the movable housing 32 of the imaging system connector 30. It will be located outside. For this reason, when the pin terminal 12 is inserted into the connection chamber 35 of the movable housing 32, the guide protrusion 15 can be smoothly received from the top surface portion 32d by the side surface 32a of the movable housing 32.

  The camera module 1 may have only one of the fitting guide surface 40 and the inclined portion 15a. Even when the camera module 1 has only one of the fitting guide surface 40 and the inclined portion 15a, a component force in the Y direction is generated when the camera module 1 hits the corner of the other party. It can be smoothly received by the side surface 32a of the movable housing 32. However, the camera module 1 may have both the fitting guide surface 40 and the inclined portion 15a, and the connection chamber 35 is equal to the sum of the Y-direction component lengths of the fitting guide surface 40 and the inclined portion 15a. On the other hand, even if the pin terminal 12 is greatly displaced in the Y direction, the positional deviation can be corrected.

  The fitting guide surface 40 and the inclined portion 15a may function so that a component force in the Y direction is generated when the guide projection 15 hits the outer edge of the top surface portion 32d.

  For example, the fitting guide surface 40 and the inclined portion 15a may not have an angle of 45 ° in a side view as shown in FIGS. As this angle becomes smaller in the range of 0 to 90 degrees (closer to the horizontal), a larger positional shift in the Y direction of the pin terminal 12 with respect to the connection chamber 35 can be absorbed and becomes larger (approaching vertical). ), The pin terminal 12 can be smoothly inserted into the connection chamber 35 with a smaller sliding resistance. The fitting guide surface 40 and the inclined portion 15a may have different angles. Furthermore, the fitting guide surface 40 and the inclined portion 15a may not be flat, and may function so as to reduce sliding resistance, for example, by being configured to face each other in a convex shape. The starting point and the end point of the fitting guide surface 40 and the inclined portion 15a may be rounded and chamfered so that the guide protrusion 15 and the fitting guide surface 40 are not caught.

  As shown in FIGS. 3 to 5 and the like, a guide inclined surface 41 that guides the insertion of the pin terminal 12 is formed in the insertion port 39 of the movable housing 32 that hits the upper end of the connection chamber 35. The guide inclined surface 41 is inclined from the top surface portion 32d (horizontal direction) of the movable housing 32 extending in the X direction and the Y direction, which are directions intersecting the Z direction as the insertion direction of the pin terminal 12. The guide inclined surface 41 includes a pair of long side guide inclined surfaces 41a along the X direction (longitudinal direction) of the imaging system connector 30 and a pair of short side guide inclinations along the Y direction (short direction) of the imaging system connector 30. It has a surface 41b and is formed as a tapered surface (concave surface) having a truncated pyramid shape.

  When the camera module 1 has such a guide inclined surface 41, when the pin terminal 12 is inserted into the connection chamber 35, the fitting guide surface 40 flows through the guide protrusion 15, and the pin terminal 12 is What is necessary is just to be comprised so that it may be located in the guidance inclined surface 41 at least. That is, by positioning the pin terminal 12 on the guide inclined surface 41, the pin terminal 12 can be slid along the guide inclined surface 41 and dropped into the connection chamber 35. For this reason, when the external connection case 11 is fitted and connected to the imaging component case 21, the pin terminal 12 can be smoothly inserted into the connection chamber 35. At this time, the camera module 1 includes the guide protrusion 15 and the fitting guide surface 40, so that the camera module 1 can be fitted to the imaging system connector 30 even when the range of the guide inclined surface 41 is smaller. A sufficient displacement tolerance (induction amount) in the Y direction of the pin terminals 12 to be connected is sufficiently ensured.

  The guide inclined surface 41 is formed as a flat surface as shown in FIG. However, the guide inclined surface 41 may be formed as a curved surface. For example, if the guiding inclined surface 41 is a curved surface convex upward (Z direction), the reaction force received by the pin terminal 12 becomes lighter as the insertion of the pin terminal 12 into the connection chamber 35 proceeds. Can be smoothly inserted into the connection chamber 35.

  Here, a configuration in which two pin terminals 12, connection chambers 35, guide protrusions 15, and fitting guide surfaces 40 are arranged along the Y direction will be described.

  As shown in FIG. 1 and the like, the pin terminal 12 includes a first pin terminal 13 and a second pin terminal 14, which are in the Y direction, which is a direction intersecting the insertion direction of the pin terminal 12. Are arranged along. Similarly, as shown in FIG. 4 and the like, the connection chamber 35 includes a first connection chamber 36 and a second connection chamber 37, which are arranged along the Y direction. The guide inclined surface 41 includes a pair of first guide inclined surfaces 42 provided in the insertion port 39 of the first connection chamber 36 and a pair of second guide inclined surfaces provided in the insertion port 39 of the second connection chamber 37. 43. As shown in FIG. 5 and the like, the pair of first guide inclined surfaces 42 and the pair of second guide inclined surfaces 43 are both angles in a side view starting from the boundary between the top surface portion 32d and the insertion port 39. Has an inclination of 45 ° and extends downward in the Z direction. And in this embodiment, as shown in FIG. 4 etc., a pair of fitting guidance surfaces 40 and 40 are both outward in the Y direction across the first connection chamber 36 and the second connection chamber 37. positioned.

  When the first pin terminal 13 is located outside the range of the first guide inclined surface 42 in the Y direction, for example, to the right in FIG. The middle left) and one of the pair of fitting guide surfaces 40 (left in FIG. 5) are in contact with each other. When the pin terminal 12 is inserted into the connection chamber 35, when one of the guide protrusions 15 and one of the fitting guide surfaces 40 come into contact, the fitting guide surface 40 applies a component force in the Y direction from the guide protrusions 15. By receiving the “connector housing” (here, the imaging system connector 30. In FIGS. 5 to 7, the movable housing 32 is not displaced with respect to the fixed housing 31. .) Is relatively displaced to the right in the Y direction. As a result, when the pin terminal 12 is initially inserted into the connection chamber 35, the first guiding inclined surface 42 is positioned under the first pin terminal 13 (see FIG. 5) that has been shifted to the right of the insertion port 39. (See FIG. 6). As described above, the camera module 1 is configured to position the pin terminal 12 at the insertion port 39, at least the guiding inclined surface 41, when the pin terminal 12 is inserted into the connection chamber 35.

  In the camera module 1, when the second pin terminal 14 is located outside the range of the second guide inclined surface 43, for example, to the left in FIG. 5, the other of the guide protrusions 15 (right in FIG. 5). And the other (right side in FIG. 5) of the fitting guide surface 40 is comprised. Accordingly, the movable housing 32 is the same as described above except that the displacement direction of the movable housing 32 is leftward.

  Thus, according to the camera module 1, when the external connection case 11 is fitted and connected to the imaging component case 21, the first pin terminal 13 is guided to the inclined inclined surface 41 with respect to the first connection chamber 36. Even if the position of the first pin terminal 13 and the image pickup system connector 30 are shifted in the Y direction, the first position of the pin terminal 13 and the imaging system connector 30 can be fitted and connected at the correct position. Similarly, even if the second pin terminal 14 is largely displaced in the Y direction on the opposite side beyond the guide inclined surface 41 with respect to the second connection chamber 37, the positional deviation can be corrected. The two pin terminals 14 and the imaging system connector 30 can be fitted and connected at the correct positions. That is, even if the camera module 1 is downsized and, for example, the interval between the first connection chamber 36 and the second connection chamber 37 is narrower, the pin terminals 12 that are conductively connected to the imaging system connector 30. It is possible to ensure a sufficient amount of deviation (induction amount) in the Y direction.

  When the external connection case 11 is fitted and connected to the imaging component case 21, the effect of the camera module 1 can be exerted by shifting the relative position in the Y direction. However, the effect of the camera module 1 is further exhibited when the imaging system connector 30 on the imaging component case 21 side is a movable connector. Compared to the state before the external connection case 11 is fitted and connected to the imaging component case 21 shown in FIG. 2, FIG. 8 shows a state where the movable housing 32 is displaced with respect to the fixed housing 31. Yes.

  That is, when the external connection case 11 is fitted and connected to the imaging component case 21, if a pressing force in the Z direction acts between the fitting guide surface 40 and the inclined portion 15 a of the guide protrusion 15, the Y direction The component force of is generated. In this case, since the movable housing 32 can be displaced with respect to the fixed housing 31 in the case of a movable connector, the movable housing 32 is displaced even if the external connection case 11 itself is not displaced in the Y direction. Is positioned at the insertion port 39 of the connection chamber 35. Therefore, the camera module 1 is applied to the movable connector, so that the operator does not notice that the external connection case 11 is moved in the Y direction with respect to the imaging component case 21, and the pin terminal 12 and the connection chamber 35. The position shift in the Y direction can be automatically absorbed halfway.

  As shown in FIGS. 3 and 5, the movable housing 32 has a protection portion 44 that extends downward from the fitting guide surface 40 in the Z direction so as to cover the elastic deformation portion 33 c. As described above, the elastic deformation portion 33 c is disposed between the frame-shaped peripheral wall 31 a of the fixed housing 31 and the rectangular parallelepiped lower portion 32 b of the movable housing 32. And since the elastic deformation part 33c is comprised so that it may extend in reverse U shape in order to ensure the spring length as a movable connector, it will be easy to expose in the part close | similar to the surface of the imaging system connector 30 as it is. Corresponding to such an elastic deformation portion 33c, a protection portion 44 is provided on the outer side in the Y direction of the peripheral wall 31a.

  The protection part 44 should just be formed in the outer side in the Y direction at least than the elastic deformation part 33c. In the present embodiment, the protective portion 44 is disposed outwardly in the Y direction of the peripheral wall 31a as a guideline that does not contact the elastic deformation portion 33c when the movable housing 32 is displaced.

  Thus, in the camera module 1, since the protection part 44 is formed so as to cover the elastic deformation part 33c, the operator's finger, external parts, etc. unintentionally contact the elastic deformation part 33c and elastically deform. It is possible to prevent the portion 33c from being damaged.

  As shown in FIGS. 4 and 5 and the like, the fitting guide surface 40 is formed to protrude outward in the Y direction from the leg portion 33a. As a result, a sufficient amount of displacement (induction amount) in the Y direction of the pin terminal 12 fitted and connected to the imaging system connector 30 is sufficiently ensured. Thus, with respect to the fitting guide surface 40 formed with a larger length in the Y direction, as shown in FIGS. 3 and 4, the Y direction corresponds to the leg portion 33 a. A recess 45 that is missing inward is formed. Since the protector 44 is formed on the fitting guide surface 40 of the present embodiment, the recess 45 is formed as a quadrangular prism-like space through the fit guide surface 40 and the protector 44. Has been.

  In the present embodiment, four leg portions 33a are arranged along the X direction. The fitting guide surface 40 is formed between the outer leg portions 33a and 33a in the X direction. Accordingly, the recess 45 is provided corresponding to the two inner leg portions 33a and 33a in the X direction.

  As shown in FIG. 4 and the like, the recess 45 is formed so that the length in the X direction is longer than the leg portion 33a. Therefore, the leg portions 33a and 33a can be seen through the recess 45 even when the viewpoint is slightly tilted in the X direction from right above the movable housing 32 in the Z direction or the movable housing 32 is displaced in the X direction. is there.

  Thus, even if the fitting guide surface 40 is formed in a larger range in the Y direction, for example, by being formed large or protruding outward in the Y direction, A recess 45 is formed to make the leg 33a of the terminal 33 visible in the Z direction. For this reason, the camera module 1 can confirm the joining state to the board | substrate 24b of the leg part 33a by visual observation or an image test. Therefore, the reliability of the camera module 1 can be improved while sufficiently ensuring the allowable displacement amount (induction amount) of the pin terminal 12 electrically connected to the connector terminal 33 in the Y direction.

  As described above, according to the present embodiment, the external connection case 11 has the guide protrusion 15 that protrudes along the side surface 32 a of the movable housing 32. On the other hand, in the movable housing 32, when the pin terminal 12 is inserted into the connection chamber 35 of the movable housing 32 on the outer edge of the top surface portion 32 d facing the external connection case 11, the guide protrusion 15 is moved from the top surface portion 32 d to the movable housing 32. The side surface 32a has a fitting guide surface 40 to be received.

  For example, if the external connection case 11 is downsized corresponding to the downsizing of the harness connector and the arrangement interval between the first pin terminals 13 and the second pin terminals 14 is narrowed, the first The distance between the connection chamber 36 and the second connection chamber 37 is also narrowed. Under such circumstances, the first guide inclined surface 42 and the second guide inclined surface 43 are formed to be large, and the displacement allowable amount of the insertion position of the imaging system connector 30 connected to the external connection case 11 (the amount of induction or the movable amount) It is difficult to ensure a sufficient amount of movement of the housing 32.

  However, in the present embodiment, the alignment structure of the guide protrusion 15 of the external connection case 11 and the fitting guide surface 40 of the movable housing 32, not the guide inclined surface 41, absorbs the displacement of the pin terminal 12 with respect to the connection chamber 35. Is used. That is, even when the pin terminal 12 is out of the range of the guide inclined surface 41, the guide protrusion 15 contacts the fitting guide surface 40, whereby the external connection case 11 moves relative to the imaging system connector 30. To do. For this reason, according to the present embodiment, even if the interval between the pin terminal 12 and the connection chamber 35 is narrowed, an allowable displacement (insertion amount or movable housing 32) of the insertion position of the imaging system connector 30 connected to the external connection case 11 is achieved. Can be secured sufficiently.

  As described above, according to the camera module 1 of the present embodiment, the position by the guide protrusion 15 of the external connection case 11 and the fitting guide surface 40 of the movable housing 32 while reducing the size of the external device connected to the pin terminal 12. The pin terminal 12 and the connector terminal 33 can be reliably connected using the mating structure. Furthermore, according to the camera module 1 of the present embodiment, since the displacement of the insertion position of the pin terminal 12 can be absorbed even if the amount of the lead-in of the movable housing 32 cannot be sufficiently secured, the movable housing 32 and thus the imaging. The system connector 30 can be reduced in size.

Modification of the embodiment

  Since the camera module 1 as described above can be modified, an example thereof will be described.

  In the embodiment, the example in which the positional deviation in the Y direction is absorbed is shown. However, the positional deviation of the pin terminal 12 with respect to the connection chamber 35 can be absorbed also in the X direction. This is achieved, for example, by providing the fitting guide surface 40 on the outer edge in the X direction of the top surface portion 32d and providing the guide protrusion 15 on the external connection case 11 along the side surface 32a in the X direction of the imaging system connector 30. be able to. Furthermore, the fitting guide surface 40 and the guide protrusion 15 can be provided in a circular shape, instead of being provided separately in the X direction and the Y direction.

  In the embodiment, an example in which the number of pin terminals 12 is eight has been described. However, the number of pin terminals 12 is not limited as long as it is one or more.

  In the above-described embodiment, an example has been described in which the distances between the connector connecting portions 13a and the connector connecting portions 14a adjacent to each other are all the same length. However, these separation distances may be different. For example, some of the separation distances may be lengthened and some may be shortened. According to this, the structure of the connection chamber 35 provided in the movable housing 32 of the imaging system connector 30 can be diversified. Such a modification can be similarly applied to the external output connecting portion 13b and the external output connecting portion 14b. According to this, the shape of the harness connector can be diversified.

  In the above-described embodiment, an example in which the bent portions 13c and the bent portions 14c of all the pin terminals 12 have a twisted bent shape that bends in two directions of the X direction and the Y direction has been described. However, the bent portion 13c and the bent portion 14c may have a shape that is bent only in the X direction or only in the Y direction. Further, one pin terminal 12 adjacent to each other, for example, the first pin terminal 13 has a straight pin shape lacking the bent portion 13c, and the other pin terminal 12, for example, the second pin terminal 14 has the bent portion 14c. It can also be provided.
