Description

  The present invention relates to an electric device such as an in-vehicle camera device connected to an external device via an external harness.

For example, what is shown in FIG. 5 is proposed as background art for connecting the in-vehicle camera device to another control device or a power source.

  As shown in FIG. 5, the in-vehicle camera device 1 has a structure in which a substrate 2 on which an image sensor is mounted and a power supply circuit, a signal processing circuit, and the like are housed is housed in a case-shaped housing body 3 having a two-part structure. It is said that. Further, the in-vehicle camera device 1 is connected to another control device, a power source, or the like via the device harness 4 and the vehicle-side harness 5.

One end of the vehicle-side harness 5 is connected to other control devices, a power source, and the like, and the harness-side connector 6 is connected to the other end. The vehicle-side harness 5 is generally composed of a group of electric wires 5a having a relatively large diameter (for example, a cross-sectional area of 0.75 mm ² ).

  A device-side connected connector 7 is connected to one end of the device harness 4, and the device harness 4 is connected to the vehicle-side harness 5 through a connector connection between the device-side connected connector 7 and the harness-side connecting connector 6. It is supposed to be a structure. Further, a board connection connector 8 is connected to the other end of the equipment harness 4, and the equipment harness 4 is connected via a connector connection between the connection connector 8 and the board connector 9 provided on the board 2. The structure is connected to the substrate 2.

Moreover, the part by the side of the vehicle side harness 5 among the said apparatus harnesses 4 is made into the 1st apparatus harness part 10 comprised by the electric wire 10a group of comparatively large diameter (for example, cross-sectional area 0.75mm < ² >), The portion on the substrate 2 side is a second equipment harness portion 11 constituted by a group of electric wires 11 a having a relatively small diameter (for example, a cross-sectional area of 0.15 mm ² ), and these are connected via a connection portion 12. Has been.

  Here, the reason why the device harness 4 is composed of the first device harness portion 10 and the second device harness portion 11 is as follows.

  That is, since the board connector 9 provided on the board 2 is very small, it is necessary to use a board connector 8 to be connected to the board connector 9 having a small size. Then, it is necessary to use a relatively thin wire as an electric wire connected to each connector terminal of the board connection connector 8, and accordingly, a relatively thin wire 11 a on the board 2 side of the equipment harness 4. It is necessary to use the 2nd apparatus harness part 11 comprised by a group.

  On the other hand, the vehicle-side harness 5 attached to the vehicle side is composed of a group of relatively large-diameter electric wires 5a because of the demand for bending resistance, so that the harness is connected to the end of the vehicle-side harness 5 in accordance with this. It is necessary to use a large connector as the side connection connector 6. Then, it is necessary to use a large-sized device-side connected connector 7 connected to the harness-side connecting connector 6, and furthermore, as an electric wire connected to each connector terminal of the large-sized device-side connected connector 7. It is necessary to use a relatively large diameter. Therefore, it is necessary to use the 1st apparatus harness part 10 comprised by the vehicle side harness 5 side among the apparatus harnesses 4 by the relatively large diameter electric wire 10a group.

  For these reasons, the device harness 4 is composed of a first device harness portion 10 and a second device harness portion 11.

  Further, since the connecting portion 12 is disposed outside the housing body 3, it needs to be waterproofed. For example, as disclosed in Patent Document 1, the connection portion between the wires is covered with a heat-shrinkable tube, and the periphery thereof is sealed with an epoxy resin or the like as disclosed in Patent Document 1, for example. There is technology to do.

  Further, in this background art, the board connector 9 is connected to the board connector 9 on the board 2 side, and the equipment harness 4 is pulled out of the housing body 3 through the lead-out hole formed in the housing body 3. Yes. In this drawer hole portion, a grommet 13 made of rubber or the like is interposed between the peripheral edge of the drawer hole and the equipment harness 4 to prevent water from entering the housing body 3. Further, outside the housing body 3, the harness side connection connector 6 and the device side connected connector 7 are connected to each other, and the device harness 4 and the vehicle side harness 5 are connected.

Here, the external harness 21 constitutes a vehicle-side harness in which an external connector 22 as a harness-side connector is attached to end portions of the plurality of electric wires 21a. As each electric wire 21a, one having a relatively large diameter (for example, a cross-sectional area of 0.75 mm ² ) is used from the viewpoint of bending resistance.

  As for the external connector 22, the connector terminal 22b (for example, female terminal) corresponding to each said electric wire 21a is each incorporated in the connector housing 22a. That is, as each connector terminal 22b, the thing of the shape which can crimp the said comparatively large diameter electric wire 21a according to the diameter of the said electric wire 21a is used.

In this state, each waterproof plug 22c is configured to seal each other between the connector housing 22a and each electric wire 21a in a liquid-tight manner.

  The on-vehicle camera device 20 has a structure including a circuit board 24 as an internal electrical component and a camera housing 25 as a case-like housing body that can accommodate the circuit board 24 therein.

  On the circuit board 24, an image sensor 26 such as a CCD element and a board connector 27 as a component side connector are mounted, and a power supply circuit, a signal processing circuit, and the like related to the image sensor 26 are formed. The board connector 27 is provided with a connector terminal 27a (for example, a male terminal) for supplying power to the circuit board and for sending and receiving signals. The circuit board 24 is configured to be housed and fixed in the camera housing 25 by screwing or the like at a position and posture at which the image sensor 26 can capture an external scenery.

  The camera housing 25 has a two-part structure of a front case portion 25a and a rear case portion 25b. The camera housing 25 is appropriately combined with a screw member or the like via a sealing material so as to be combined in a liquid-tight manner. Yes.

Of course, one connector terminal 28a, one connector terminal 28b corresponding to this, and the connection conductor 30 connecting them are composed of separate members or a single member. Either may be sufficient. In particular, in the latter case, the configuration can be further simplified.

  At this time, since the board connector 27 mounted on the circuit board 24 is very small, a small connector terminal 27a incorporated therein is used. A small connector terminal 28a in the inner connector portion 28 connected to the board connector 27 is also used.

  On the other hand, as the connector terminal 22 b in the external connector 22 on the external harness 21 side, a relatively large connector terminal 22 b is used in accordance with the relatively large diameter electric wire 21 a in the external harness 21. As the connector terminal 29a in the outer connector portion 29 connected to the external connector 22, a large connector is used in accordance with the relatively large connector terminal 22b.

  The present embodiment is configured as described above, and the inner connector portion 28 is integrally formed on the inner surface side of the rear case portion 25b, and the outer connector portion 29 is integrally formed on the outer surface side. Each connector terminal 28a and each connector terminal 29a of the outer connector portion 29 are connected by connecting conductors 30 embedded in the rear case portion 25b. When the vehicle camera device 20 is assembled, The board connector 27 of the circuit board 24 may be connected to the inner connector part 28 of the rear case part 25b, and the front case part 25a and the rear case part 25b may be assembled with each other. Assembling workability can be improved because there is no need to penetrate through 4.

  Further, since each connector terminal 28a of the inner connector portion 28 to which the board connector 27 is connected and each connector terminal 29a of the outer connector portion 29 to which the external connector 22 is connected are connected by the connection conductor 30, respectively. It is not necessary to change the wire diameter in the wire path as in the technology.

  And the change of the wire diameter which was performed outside the in-vehicle camera device 1 of the background art is also used as the connection conductor 30 in the rear case portion 25b, and the external connection harness 4 is provided as in the background art. There is no need to pull it out and it can be made compact.

  In addition, unlike the background art, there is no need to connect a relatively large-diameter wire and a relatively small-diameter wire and perform a waterproof treatment outside the apparatus, simplifying the structure and facilitating manufacturing, and reducing costs. There is an advantage that reduction can also be achieved.

  Furthermore, when connecting the wires, the in-vehicle camera device 20 can be connected to an external device by directly connecting the external connector 22 of the external harness 21 to the outer connector portion 29 of the camera housing 25, thereby facilitating connection work. Can be achieved.

  Further, the rear case portion 25b has a structure in which the inner connector portion 28 and the outer connector portion 29 are integrally formed, and the structure can be simplified by reducing the number of parts, and the rear case portion 25b, the inner connector portion 28 and the outer connector portion can be simplified. There is an advantage that waterproofing between the two can be ensured.

  Further, a waterproof sealant or the like is disposed between the inner surface of the outer side of the fitting concave portion of the outer connector portion 29 to which the outer connector 22 is fitted and the outer surface of the outer connector 22 so that the connector is waterproof when connected. A waterproof structure may be employed.

  Thus, by adopting a waterproof structure, it is possible to effectively prevent water from entering the outer connector portion 29 and the camera housing 25.

  In manufacturing the rear case portion 25b including the inner connector portion 28 and the outer connector portion 29, for example, the terminal conductors integrally including the connector terminal 28a, the connection conductor 30, and the connector terminal 29a are arranged at predetermined positions. In this state, it can be easily manufactured by integral molding with resin, for example, insert molding.

  Further, after integrally forming the rear case portion 25b including the inner connector portion 28 and the outer connector portion 29 with a flexible resin, a terminal conductor in which the connector terminal 28a, the connection conductor 30, and the connector terminal 29a are integrally provided, For example, a structure may be adopted in which the outer connector portion 29 is inserted and attached and held in a retaining shape by a suitably provided locking mechanism.

  In this case, the flexible resin forming the rear case portion 25b is preferably formed of a connector resin such as polybutylene terephthalate (PBT), nylon, or polyphenylene sulfide (PPS). Thereby, the structure for connectors, such as a lock part and a to-be-locked part, can be easily formed in the rear case part 25b.

  FIG. 2 shows a second embodiment, and the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  That is, in the present embodiment, the outer connector portion 29 of the in-vehicle camera device 20 and the external harness 21 are electrically connected via the relay harness 32.

  The relay harness 32 uses a desired number of relatively large-diameter wires 32a similar to the wires 21a. In addition, since each electric wire 32a is comparatively short, it does not need to be a shield electric wire. At one end of each electric wire 32a, a connection terminal 33 (for example, male terminal) connected to each connector terminal 29a (for example, female terminal) of the outer connector portion 29 is a waterproof plug 34 made of rubber, flexible resin, or the like. When each connection terminal 33 is connected to each connector terminal 29a, each waterproof plug 34 is in close contact with the inner peripheral surface of each recess in which each connector terminal 29a is accommodated in a liquid-tight manner. It is structured.

  Further, a relay connector 35 that can be connected to the external connector 22 of the external harness 21 is attached to the other end of each electric wire 32a. The relay connector 35 is connected to each of the external connectors 22 in the connector housing 35a. Connector terminals 35b (for example, female terminals) connected to the connector terminals 22b (for example, male terminals) are respectively incorporated.

  Further, waterproof plugs 35c made of rubber, flexible resin, or the like are respectively attached to ends of the electric wires 32a to which the connector terminals 35b are crimped, and the connector terminals 35b are incorporated into the connector housing 35a. In this state, each waterproof plug 35c is configured to seal each other between the connector housing 35a and each electric wire 32a in a liquid-tight manner.

  Then, when wiring connection to the in-vehicle camera device 20, each connector terminal 29a of the outer connector portion 29 formed integrally with the outer surface of the rear case portion 25b is attached to each end of each electric wire 32a of the relay harness 32. Each of the connection terminals 33 is connected, and the relay connector 35 at the other end is connected to the external connector 22 of the external harness 21, so that the circuit board 24, which is an internal electrical device, is connected to the external control device via the relay harness 32. Or an external device such as an external power source.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained, and the outer connector portion 29 and the external harness 21 can be electrically connected via the relay harness 32, which can cope with diversification of connection methods.

  Further, the waterproof plugs 34 can effectively prevent water from entering the connection portions between the connector terminals 29 a of the outer connector portion 29 and the connection terminals 33 of the relay harness 32.

  Further, a waterproof sealing material or the like is disposed between the inner surface of the fitting recess of the external connector 22 to which the relay connector 35 is fitted and the outer surface of the relay connector 35. If the structure is adopted, it is possible to effectively prevent water from entering the compatible connecting portion.

  In addition, it is good also as a structure which equips the both ends of the relay harness 32 with the relay connector 35, respectively, and connects to the outer side connector part 29 also.

  FIG. 3 is an explanatory view showing an in-vehicle camera device according to the third embodiment, and FIG. 4 is a view showing a rear case portion of the device. In the third embodiment, an example in which an in-vehicle camera device is assumed as an electric device will be described.

  This in-vehicle camera device 120 includes a circuit board 124 as an internal electrical component, and a camera housing 125 as a case-like housing body that can accommodate the circuit board 124 therein.

  An image sensor 126 such as a CCD element is mounted on the circuit board 124, and a power supply circuit, a signal processing circuit, and the like related to the image sensor 126 are formed.

  A power supply or signal transmission / reception wiring member 127a is drawn from the circuit board 124, and a single connector 127 is attached to the end of the wiring member 127a. The circuit board 124 receives power supply from the outside via the connector 127 or transmits / receives signals to / from the outside. In addition, as the wiring material 127a, FFC (flexible flat cable), FPC (flexible printed circuit board), etc. other than a single wire are used.

  In addition, the circuit board 124 is configured to be housed and fixed in the camera housing 125 by screwing or the like at a position and posture at which an external scene can be imaged by the image sensor 126.

  The camera housing 125 has a two-part structure of a front case part 125a and a rear case part 125b, and is structured to be combined in a liquid-tight manner by combining them together by screwing or the like through an appropriate sealing material. ing.

  The front case portion 25a is formed of resin or the like, and a predetermined optical system 125e including a lens or the like is incorporated in one main surface thereof. And the image pick-up element 126 in the camera housing 125 is comprised so that the external scenery of a predetermined range may be imaged through the said optical system 125e.

  The rear case portion 125b is also formed of resin or the like, and a plurality of (here, four) relay terminal members 130 are provided on one main surface thereof in an appropriate arrangement (here, a substantially rectangular arrangement).

  Each relay terminal member 130 is a long conductive member, and one end portion thereof is formed with a smaller diameter than the other end portion. The end on the small diameter side of each relay terminal member 130 is an inner connector terminal 130a, and the end on the large diameter side is an outer connector terminal 130b. That is, one inner connector terminal 130a, one outer connector terminal 130b corresponding to the inner connector terminal 130a, and a connection conductor (in this case, an intermediate portion of the relay terminal member 130) connecting them are configured by a single conductive member. Will be.

  Such a relay terminal member 130 is formed by, for example, punching a metal plate into an appropriate shape, and is a member obtained by applying Sn plating to a base material such as annealed copper. In order to improve connection reliability, it is preferable to apply gold plating to the inner diameter connector terminal 130a portion on the small diameter side that tends to have a smaller contact area with the counterpart terminal. Further, the terminal shapes of the inner connector terminal 130a and the outer connector terminal 130b of the relay terminal member are preferably formed in a square shape in order to reduce the cost. In this case, in order to improve the connection reliability with the mating terminal, the contact surface with the mating terminal is a smooth surface (the surface that was the surface of the base plate material) that is not a shearing surface during the terminal material shearing process. It is preferable that

  Of course, each part of the relay terminal member 130 may be constituted by separate members, and these members may be connected later by soldering or welding.

  Each relay terminal member 130 has one main surface of the rear case portion 125b in a posture in which the inner connector terminal 130a protrudes into the rear case portion 125b and the outer connector terminal 130b protrudes outward of the rear case portion 125b. Is insert molded.

  The inner connector portion 128 is constituted by a plurality of inner connector terminals 130a protruding in a predetermined arrangement in the rear case portion 125b. Then, by connecting the connector 127 to the inner connector portion 128, each connector terminal (for example, female terminal) on the connector 127 side is electrically connected to each inner connector terminal 130a.

  In addition, a connector housing 125c that extends outward so as to surround a group of outer connector terminals 130b is integrally formed on the outer side of the main surface of the rear case portion 125b. A lock portion 125d for engaging and holding the connected state with the mating connector is formed on the outer peripheral portion of the connector housing 125c. The connector housing 125c and each outer connector terminal 130b constitute an outer connector portion 129. Then, by connecting the external connector 22 having the same configuration as described in the first embodiment to the external connector portion 129, each connector terminal 22b (for example, a female terminal) on the external connector 22 side corresponds. It is electrically connected to each outer connector terminal 130b.

  Here, the reason why the inner connector terminal 130a is formed with a relatively small diameter and the outer connector terminal 130b is formed with a relatively large diameter is based on the same reason as described in the first embodiment.

  That is, for reasons of space in the camera housing 125 and the like, it is necessary to use a thin and small wiring material as the wiring material in the housing 125. Accordingly, a thin connector terminal for the connector 127 is required. It is necessary to use it. In accordance with this, the inner connector terminal 130a connected to the connector 127 side also needs to be formed with a small diameter.

  On the other hand, as the connector terminal 22b in the external connector 22 on the external harness 21 side, a relatively large-diameter connector terminal 22b is used in accordance with the relatively large-diameter electric wire 21a in the external harness 21. In accordance with this, it is necessary to form the outer connector terminal 130b of the outer connector portion 129 connected to the external connector 22 with a relatively large diameter.

  When assembling the in-vehicle camera device 120 configured in this way, the connector 127 on the circuit board 124 side is connected to the inner connector portion 128 formed on the inner surface of the rear case portion 125b, and the front case portion 125a and the rear case portion 125a are connected. What is necessary is just to assemble | attach with the case part 125b.

  When wiring connection is made to the in-vehicle camera device 120 assembled in this way, the external connector 22 of the external harness 21 is connected to the outer connector portion 129 integrally formed on the outer surface of the rear case portion 125b. . As a result, the circuit board 124 which is an internal electric device is connected to the external control device, the external power source, etc. via the connector 127, the inner connector portion 128, each relay terminal member 130, the outer connector portion 129, the external connector 22 and the external harness 21. It is electrically connected to external equipment.

  According to the in-vehicle camera device 120 configured as described above, the same effects as those of the first embodiment can be obtained.

  Moreover, since each end part of the relay terminal member 130 insert-molded in the rear case part 125b constitutes the inner connector terminal 130a and the outer connector terminal 130b, the structure can be simplified and the assembly can be facilitated. Can contribute to cost reduction. Moreover, since the relay terminal member 130 insert-molded so as to penetrate the rear case portion 125b from inside to outside performs signal transmission and reception, power feeding, etc., it is excellent in waterproofness.

  In addition, by changing the length of the external harness 21 and the like, it is possible to easily cope with changes in the installation position and orientation of the in-vehicle camera device 120 and the type of vehicle to be installed.

  In the first to third embodiments, the example in which the inner connector 28 and the board connector 27 or the inner connector terminal 130a and the connector 127 are connected to each other has been described. However, this is not always necessary. For example, instead of the connector terminal 28a or the inner connector terminal 130a, an inner terminal portion that can be soldered or welded is formed, and a lead wire, FFC (flexible flat cable) or FPC (FPC) that is a wiring member on the substrate 24, 124 side is formed. A flexible printed circuit board or the like may be connected to the inner terminal portion by soldering or welding.

  Of course, the matters disclosed in the first to third embodiments can be appropriately combined and employed. For example, in the third embodiment, the relay harness 32 in the second embodiment may be used.
