DETAILED DESCRIPTION OF THE INVENTION

[0014] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0015] MID (Molded Interconnect Device) refers to a resin molded product with wiring and electrodes formed on it.

[0016] In this embodiment, the resin molded product is formed by injection molding. [Example]

[0017] A first embodiment of the present invention will be described below with reference to FIGS.

[0018] (Block diagram showing an example configuration of a digital camera 100) 1 is a block diagram showing an example of the configuration of a digital camera (hereinafter referred to as camera) 100 according to this embodiment. The camera 100 is an interchangeable lens camera to which a lens unit 200 can be attached or detached.

[0019] FIG. 2 is a perspective view of the appearance of the camera 100. As shown in FIG.

[0020] The lens unit 200 shown in FIG. 1 is fixed to the camera 100 by a lens mount 201 provided on the lens unit 200 and a lens mount 101 provided on the camera 100 .

[0021] The lens unit 200 and the camera 100 are configured to be able to communicate with each other via a connector 202 provided on the lens unit 200 and a connector 102 provided on the camera 100 .

[0022] Specifically, the system control unit 307 and the lens drive control unit 203 communicate with each other, and based on a signal from the system control unit 307, the lens drive control unit 203 controls the lens drive unit 204, and the lens drive unit 204 drives the aperture 211 and the lens 210.

[0023] The lens 210 is used to form an optical image from a subject onto the image sensor 302 .

[0024] The shutter 301 is disposed between the image sensor 302 and the lens 210, and blocks light from the lens 210 to the image sensor 302 when not capturing an image.

[0025] During photography, the shutter 301 opens under the control of the system control unit 307 to allow an optical image formed by the lens 210 onto the image sensor 302 .

[0026] The image sensor 302 is an image sensor that is configured with a CCD, CMOS, or the like, and converts an optical image into an electrical signal.

[0027] The A / D converter 304 converts the analog signal into a digital signal. The A / D converter 304 is used to convert the analog signal output from the image sensor 302 into a digital signal.

[0028] The image processing unit 305 performs predetermined pixel interpolation, resizing such as reduction, and color conversion processing on the data from the A / D converter 304 or the data from the memory control unit 306 .

[0029] Furthermore, the image processing unit 305 performs predetermined calculation processing using the captured image data, and the system control unit 307 performs exposure control and distance measurement control based on the obtained calculation results.

[0030] This allows TTL (through-the-lens) AF (autofocus), AE (auto-exposure), and EF (pre-flash) processing to be performed.

[0031] The image processing unit 305 also performs predetermined calculation processing using the captured image data, and also performs TTL type AWB (auto white balance) processing based on the obtained calculation results.

[0032] The output data from the A / D converter 304 is written into a memory 308 via an image processing unit 305 and a memory control unit 306 , or directly via the memory control unit 306 .

[0033] The memory 308 stores image data converted into digital data by the A / D converter 304 for display on the display unit 105 or the display unit 106 .

[0034] The memory 308 also serves as a memory for displaying images (video memory).

[0035] The D / A converter 309 converts the image display data stored in the memory 308 into an analog signal and supplies it to the display unit 105 or the display unit 106 .

[0036] In this way, the image data for display written in the memory 308 is displayed on the display unit 105 or 106 via the D / A converter 309 .

[0037] The display unit 105 and the display unit 106 display, on a display device such as an LCD, an analog signal from the D / A converter 309 .

[0038] The digital signal that has been A / D converted once by the A / D converter 304 and stored in the memory 308 is converted to analog by the D / A converter 309 .

[0039] Then, by sequentially transferring and displaying the images on the display unit 105 or the display unit 106, a through image display (live view display) can be performed.

[0040] The nonvolatile memory 310 is a memory serving as an electrically erasable and recordable recording medium, and may be, for example, an EEPROM.

[0041] The nonvolatile memory 310 stores constants, programs, etc. for the operation of the system control unit 307.

[0042] The system control unit 307 is a control unit that has at least one processor, and controls the entire camera 100 and the lens unit 200 .

[0043] A RAM is used for the system memory 311. In the system memory 311, constants and variables for the operation of the system control unit 307, programs read from the nonvolatile memory 310, and the like are developed.

[0044] The system control unit 307 also controls the memory 308, the D / A converter 309, the display units 105 and 106, and so on, thereby performing display control.

[0045] The system timer 312 is a timekeeping unit that measures the time used for various controls and the time of a built-in clock.

[0046] The first shutter switch 104a is turned on when the shutter button 104 provided on the camera 100 is pressed halfway (a shooting preparation instruction) during operation, and generates a first shutter switch signal SW1.

[0047] The first shutter switch signal SW1 starts operations such as AF (autofocus) processing, AE (auto exposure) processing, AWB (auto white balance) processing, and EF (pre-flash) processing.

[0048] The second shutter switch 104b is turned on when the shutter button 104 is fully pressed (a photographing instruction) and generates a second shutter switch signal SW2.

[0049] The system control unit 307 causes the shutter 301 to drive the shutter blades 301a using the second shutter switch signal SW2.

[0050] Then, a series of operations for image capture processing, from reading out signals from the image sensor 302 to writing image data to the recording medium 330, is started.

[0051] The shutter blades 301a move at high speed inside the shutter 301 in a direction perpendicular to the optical axis of the lens 210, and stop moving instantly when they collide with a stopper member (not shown) inside the shutter 301.

[0052] By selecting and operating various function icons displayed on the display units 105 and 106, the various operation members of the operation unit 108 are assigned appropriate functions for each situation, and act as various function buttons.

[0053] The function buttons include, for example, an end button, a back button, an image forward button, a jump button, a narrow down button, an attribute change button, and the like.

[0054] For example, when the menu button is pressed, a menu screen in which various settings can be made is displayed on the display unit 105 or the display unit 106.

[0055] The power supply is turned on / off by a power switch 103 .

[0056] The power supply control unit 313 is configured with a battery detection circuit, a DC-DC converter, a switch circuit for switching between blocks to be energized, and the like, and detects whether a battery is installed, the type, and the remaining capacity.

[0057] Furthermore, the power supply control unit 313 controls the DC-DC converter based on the detection result and instructions from the system control unit 307, and supplies the necessary voltage to each unit including the recording medium 330 for the necessary period.

[0058] The power supply unit 314 is made up of a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as an NiCd battery, an NiMH battery, or a Li battery, an AC adapter, or the like.

[0059] The recording medium I / F 315 is an interface with a recording medium 330 such as a memory card or a hard disk.

[0060] The recording medium 330 is a recording medium such as a memory card for recording captured images, and is composed of a semiconductor memory, an optical disk, a magnetic disk, or the like.

[0061] The communication unit 316 is connected wirelessly or via a wired cable, and transmits and receives video signals, audio signals, and the like.

[0062] The communication unit 316 can also be connected to a wireless LAN (Local Area Network) and the Internet.

[0063] The communication unit 316 can transmit images (including through images) captured by the image sensor 302 and images recorded on the recording medium 330, and can also receive image data and various other information from external devices.

[0064] (Shake detection unit 320 / gyro sensor) The shake detection unit 320 is, for example, a gyro sensor, and detects the amount of vibration of the camera.

[0065] The shake detection unit 320 detects the vibration and vibration amount in three axial directions of the camera 100: pitch direction, yaw direction, and roll direction.

[0066] In the camera 100 shown in FIG. 1, the image sensor driver 303 controls the movement of the image sensor 302 in accordance with the amount of shake detected by the shake detector 320, thereby performing optical shake correction.

[0067] Furthermore, the image processing unit 305 performs electronic shake correction on the image in accordance with the amount of shake detected by the shake detection unit 320 under the control of the system control unit 307 .

[0068] (An exploded perspective view of the camera 100) FIG. 3 is an exploded perspective view of the camera 100 with the front, rear, and lower cover members removed.

[0069] The base plate 120 is a structure that provides the strength of the camera 100, and a shutter 301, an image sensor 302, an image sensor drive unit 303, and a system control unit 307 are fastened to the base plate 120 with screws (not shown).

[0070] The top cover unit 110 is fastened to the base plate 120 with screws (not shown).

[0071] (Perspective view of the appearance of the top cover unit 110) FIG. 4(a) is an external perspective view of the top cover unit 110, and FIG. 4(b) is an exploded perspective view of the top cover unit 110. As shown in FIG.

[0072] The top cover unit 110 is made up of a top cover member 111 that covers the top surface of the camera 100, a power switch 103, a shutter button 104, and the like.

[0073] As shown in FIG. 4( b ), the shake detection unit 320 is fastened to the center of the top cover member 111 with a screw 401 .

[0074] (Exploded perspective view of the shake detection unit 320) FIG. 5( a ) is an exploded perspective view of the shake detection unit 320 , and FIGS. 5( b ) and 5 ( c ) are perspective views of the appearance of the shake detection unit 320 .

[0075] The shake detection unit 320 is composed of plates 505 and 506, a buffer member 504, a sensor module 508, and a flexible substrate 502F.

[0076] The sensor module 508 has gyro sensors 501P, 501R, and 501Y for measuring angular velocity, and an acceleration sensor 502A for detecting acceleration.

[0077] The sensor module 508 further includes three gyro sensors 501P, 501R, and 501Y and a passive element 502R (see FIG. 6) such as a resistor or a capacitor for driving the acceleration sensor 502A.

[0078] Flexible substrate 502F has terminal portion 502D and terminal portion 502E.

[0079] The terminal portion 502D is connected to a connector 502C (see FIG. 6) that the sensor module 508 has.

[0080] Terminal section 502E is electrically connected to a connector (not shown) that forms part of the path to system control section 307.

[0081] This allows the sensor module 508 and the system control unit 307 to perform various necessary communications via the flexible substrate 502F.

[0082] Through this communication, the system control unit 307 can acquire the detection values ​​detected by the gyro sensors 501P, 501R, and 501Y and the acceleration sensor 502A.

[0083] The buffer member 504 is made of an elastic material such as sponge that absorbs vibrations.

[0084] The shake detection unit 320 has two buffer members 504 .

[0085] The two buffer members 504 are arranged on different surfaces facing the sensor module 508, and are arranged to sandwich the sensor module 508 therebetween.

[0086] In this embodiment, the gyro sensor 501Y is disposed on a surface that is approximately parallel to the main surface 503Y, which is the surface on which the gyro sensor 501Y is disposed.

[0087] Plates 505 and 506 have surfaces that are approximately parallel to main surface 503Y, and plate 505 and plate 506 sandwich sensor module 508 and buffer member 504 therebetween.

[0088] Furthermore, one of the buffer members 504 is compressed by the plate 505 and the sensor module 508, and the other of the buffer members 504 is compressed by the plate 506 and the sensor module 508.

[0089] Therefore, the plates 505 and 506 are configured not to come into contact with the sensor module 508 .

[0090] The shake detection unit 320 is completed when the plate 505 and the plate 506 are fastened together with the screw 507 .

[0091] (Perspective view of the exterior of the sensor module 508) 6(a) and 6(b) are external perspective views of the sensor module 508, and FIG. 6(c) is a cross-sectional view of the main part of the sensor module 508.

[0092] Base member 503 shown in FIG. 6 is a member for holding gyro sensors 501P, 501R, and 501Y in predetermined positions, and is made of a material such as plastic or LCP (liquid crystal polymer).

[0093] The base member 503 has a first side wall 503P that is approximately perpendicular to the rotation axis in the pitch direction, a second side wall 503R that is approximately perpendicular to the rotation axis in the roll direction, and a main surface 503Y that is approximately perpendicular to the rotation axis in the yaw direction.

[0094] In other words, the first sidewall 503P is perpendicular to the main surface 503Y, and the second sidewall 503R is perpendicular to both the main surface 503Y and the first sidewall 503P.

[0095] The gyro sensor 501P is mounted on the first side wall 503P, the gyro sensor 501R is mounted on the second side wall 503R, and the gyro sensor 501Y is mounted on the main surface 503Y.

[0096] The gyro sensors 501P, 501R, and 501Y are directly mounted on the land portions of the pattern wiring 500 on the base member 503 by soldering.

[0097] The sensor module 508 is configured as described above.

[0098] Therefore, gyro sensor 501P detects vibrations and vibration amounts in the pitch direction of camera 100, gyro sensor 501R in the roll direction, and gyro sensor 501Y in the yaw direction.

[0099] The connector 502C is mounted on the surface of the main surface 503Y opposite to the surface on which the gyro sensor 501Y is mounted.

[0100] Here, the surface of the main surface 503Y on which the gyro sensor 501Y is mounted is called a first surface 509, and the surface of the main surface 503Y on which the connector 502C is mounted is called a second surface 510.

[0101] Additionally, acceleration sensor 502A is mounted on second side wall 503R.

[0102] As shown in FIGS. 6(a) and 6(b), a pattern wiring 500 is directly wired on a base member 503.

[0103] The pattern wiring 500 is formed by MID technology.

[0104] MID technology is a technology that forms patterns by irradiating a laser onto a specific location on a base material and then applying metal plating only to the laser-irradiated areas.

[0105] Gyro sensors 501P, 501R, and 501Y for detecting shake, acceleration sensor 502A, and various passive elements 502R for driving them will be described.

[0106] Gyroscopes 501P, 501R, and 501Y, acceleration sensor 502A, and passive element 502R are mounted directly on mounting lands provided by pattern wiring 500 on base member 503 by soldering or the like.

[0107] The pattern wiring 500 enables necessary electrical connections between the gyro sensors 501P, 501R, and 501Y, the acceleration sensor 502A, the passive element 502R, and the connector 502C.

[0108] FIG. 6C is a cross-sectional view of the main part of the sensor module 508.

[0109] Here, when the thickness of the main surface 503Y is Z and the shorter of the length of the first side wall 503P and the length of the second side wall 503R in the direction perpendicular to the main surface 503Y is W, W is greater than Z.

[0110] In addition, the height of the higher of the first side wall 503P and the second side wall 503R from the first surface 509 is defined as A, and the height of the higher of the first side wall 503P and the second side wall 503R from the second surface 510 is defined as B.

[0111] Also, the height from the first surface 509 to the top surface of the gyro sensor 501Y is defined as C, and the height from the second surface 510 to the top surface of the connector 502C is defined as D.

[0112] In this case, A is greater than or equal to C, and B is greater than or equal to D.

[0113] This embodiment is configured as described above.

[0114] Therefore, the gyro sensor 501Y and the connector 502C do not protrude beyond the higher of the first side wall 503P and the second side wall 503R in the direction perpendicular to the main surface 503Y.

[0115] Therefore, the height of the sensor module 508 in the direction perpendicular to the main surface 503Y can be reduced.

[0116] FIG. 6(d) shows an enlarged view of the land 522 formed on the first side wall 503P for mounting the gyro sensor 501P.

[0117] The gyro sensor 501P is mounted on the first side wall 503P with solder by reflow mounting.

[0118] In FIG. 6(d), G indicates the direction of gravity when cream solder is melted when the gyro sensor 501P is reflow-mounted on the first side wall 503P.

[0119] Moreover, H indicates a direction that is perpendicular to the direction of gravity and parallel to the first side wall 503P.

[0120] In the case of reflow mounting on a normal flat substrate, gravity always acts on the mounted components perpendicular to the surface on which the mounted components are mounted.

[0121] However, in the case of the shake detection unit 320 of this embodiment, gyro sensors 501P, 501R, and 501Y are mounted on three surfaces that are orthogonal to each other.

[0122] Therefore, gravity acts on at least one of the gyro sensors 501P, 501R, and 501Y in a direction parallel to the surface on which the sensor is mounted during reflow mounting.

[0123] In this embodiment, the gyro sensor 501P is mounted on the first side wall 503P in a state where gravity acts in the direction of arrow G.

[0124] Therefore, when the solder melts, it may be affected by gravity in the direction of arrow G and may be displaced in the direction of arrow G from the desired mounting position.

[0125] Therefore, of the land arrays A and B, each consisting of five lands, the amount of solder applied to the lower land array B in FIG. 6(d) is made less than the amount of solder applied to the other land array A.

[0126] As a result, the surface tension of the solder applied to the land row A becomes greater than the surface tension of the solder applied to the land row B.

[0127] By doing so, the force acting on the gyro sensor 501P due to the surface tension of the solder is directed in the direction opposite to that of arrow G, thereby canceling out the gravity acting on the gyro sensor 501P in the direction of arrow G and preventing misalignment due to gravity during reflow mounting.

[0128] As shown in FIGS. 6(a) and 6(b), the base member 503 is provided with a plurality of vias 510 for electrically connecting one surface of the main surface 503Y to the other surface.

[0129] FIG. 6(e) is an enlarged perspective cross-sectional view of the base member 503 in the area where the via 510 is arranged, and FIG. 6(f) is an enlarged cross-sectional view of the base member 503 in the area where the via 510 is arranged.

[0130] The mold for molding the base member has a structure in which the main surface 503Y is the largest flat surface, and therefore productivity is improved if the mold is configured to punch in a direction perpendicular to the main surface 503Y.

[0131] Therefore, in this embodiment, the vias 510 are arranged only on the main surface 503Y, so that the direction of the holes 512 of the vias 510 coincides with the mold removal direction, thereby simplifying the mold structure.

[0132] In this embodiment, as shown in FIGS. 6(e) and 6(f), the via 510 has a hole 512 shaped like two overlapping mortars, which is formed symmetrically with respect to the center in the thickness direction of the main surface 503Y.

[0133] The mortar has a shape in which the diameter is smallest at the center in the thickness direction of the main surface 503Y and the diameter increases with increasing distance from the center in the thickness direction.

[0134] If the diameter of the circle at via vertex 515 is via diameter 514 , hole 512 opens to the surface of the base member and penetrates base member 511 while increasing in diameter at a constant via angle 513 from via vertex 515 as the starting point.

[0135] On the inner wall of the hole 512, a pattern is directly wired by MID from one side to the other side of the main surface 503Y.

[0136] Therefore, the patterns to be wired on one surface and the other surface of the base member 511 are electrically connected through the vias 510 .

[0137] The reason why the hole 512 in this embodiment is not a simple cylindrical hole penetrating the main surface Y, but has the above-mentioned shape is to make it easier to irradiate the laser onto the inner wall of the hole 512 for pattern formation.

[0138] (Side view of sensor module 508) 7A and 7B are side views of the sensor module 508, with FIG. 7A showing the first side wall 503P and FIG. 7B showing the second side wall 503R.

[0139] Here, the gyro sensors 501Y, 501R, and 501P of this embodiment are substantially rectangular when viewed from a direction perpendicular to the surface on which they are mounted.

[0140] Therefore, the gyro sensor 501R has a long side 501Ra and a short side 501Rb, and the gyro sensor 501P has a long side 501Pa and a short side 501Pb.

[0141] In this embodiment, the gyro sensor 501R and the gyro sensor 501P are attached to the base member 503 so that the short sides 501Rb and 501Pb are parallel to the direction orthogonal to the main surface 503Y.

[0142] Therefore, the height of the first side wall 503P and the second side wall 503R in the direction perpendicular to the main surface 503Y can be reduced. [Example]

[0143] Next, a sensor module according to a second embodiment of the present invention will be described with reference to FIG.

[0144] (Perspective view of the sensor module 2508) The only difference between the first embodiment and this embodiment is the sensor module, so in this embodiment, only the differences between the sensor module 2508 of the second embodiment and the sensor module of the first embodiment will be described.

[0145] FIG. 8(a) is a perspective view of a sensor module 2508 according to a second embodiment of the present invention, and FIG. 8(b) is an enlarged view of part A in FIG. 8(a).

[0146] The sensor module 2508 has, on a base member 2503, a pitch direction detection gyro sensor 2501P, a roll direction detection gyro sensor 2501R, and a yaw direction detection gyro sensor (not shown).

[0147] Three types of gyro sensors 2501P, 2501R, and 2501R are mounted on a first side wall 2503P, a second side wall 2503R, and a main surface (not shown), respectively.

[0148] The sensor module 2508 of the second embodiment differs from the sensor module of the first embodiment in the following points.

[0149] That is, a first recessed portion 2001 for wiring, a second recessed portion 2002 for wiring, and a third recessed portion 2003 for wiring are provided at the locations where the pattern wiring 2500 passes through the vertices of the first side wall 2503P and the second side wall 2503R.

[0150] Also, a fourth wiring recess 2004, a fifth wiring recess 2005, and a sixth wiring recess 2006 are provided at the locations where the pattern wiring 2500 passes through the vertices of the first side wall 2503P and the second side wall 2503R.

[0151] As shown in FIG. 8(b), a first recessed portion 2001 for wiring is provided at the top of the second sidewall 2503R where the pattern wiring 2500 passes.

[0152] Furthermore, the portion of the second side wall 2503R where the pattern wiring 2500 passes is one step lower than the other portion of the top of the second side wall 2503.

[0153] The tops of the first side wall 2503P and the second side wall 2503R are more likely to come into contact with other members, jigs, and the like than other portions.

[0154] The tops of first side wall 2503P and second side wall 2503R are locations that are likely to come into contact with other members, jigs, etc. during assembly of sensor module 2508 or when sensor module 2508 is incorporated into camera 100, etc.

[0155] Therefore, in the present invention, recesses such as the first wiring recess 2001 are provided to reduce the risk of the pattern 2503 passing through the tops of the first side wall 2503P and the second side wall 2503R being broken due to contact as described above.

[0156] The invention of this embodiment will be outlined below.

[0157] The base member is an injection molded part onto which the pattern wiring is directly formed.

[0158] The base member 503 has a protruding portion 503P that protrudes from the base surface.

[0159] The pattern wiring 2500 is laid so as to straddle the apex of the protruding portion 503P.

[0160] The protrusion 503P is characterized in that it has convex portions formed on both sides of the portion of the apex through which the pattern wiring passes. [Example]

[0161] Next, a wiring recess 3001 of a sensor module according to a third embodiment of the present invention will be described with reference to FIG.

[0162] (Enlarged view of wiring recess 3001) The only difference between the third embodiment and this embodiment is the shape of the recessed portion 3001 for wiring provided on the top of the first side wall and the second side wall.

[0163] FIG. 9 is an enlarged view of a recessed portion 3001 for wiring according to the third embodiment of the present invention.

[0164] 9, a recessed portion for wiring 3001 is provided at the top of the second side wall 3503R where the pattern wiring 3500 passes. This is different from the first recessed portion for wiring 2001 in the twelfth embodiment.

[0165] In the recessed portion for wiring 3001, protective protrusions 3002 are formed between each of the plurality of pattern wirings 3500.

[0166] The protective protrusion 3002 makes it even more difficult for the pattern wiring 3500 passing over the top of the second side wall 3503R to come into contact with other members, jigs, etc., and the risk of the pattern wiring 3500 being broken can be further reduced.

[0167] The invention of this embodiment will be outlined below.

[0168] The pattern wiring 3500 is a group of pattern wirings having a plurality of pattern wirings.

[0169] The pattern wiring group 3500 is characterized in that a convex portion 3002 is formed between at least one adjacent pattern wiring 3500 of the pattern wirings 3500 that make up the group 3500.

[0170] The pattern wiring 3500 is a group of pattern wirings made up of a plurality of pattern wirings 3500.

[0171] A feature of the pattern wiring group 3500 is that a convex portion 3002 is formed between all adjacent pattern wirings 3500 of the pattern wirings 3500 that make up the pattern wiring group 3500. [Example]

[0172] Next, a wiring recess 4001 of a sensor module according to a fourth embodiment of the present invention will be described with reference to FIG.

[0173] The only difference between the fourth embodiment and this embodiment is the shape of the recessed portions 4001 for wiring provided on the tops of the first and second side walls.

[0174] FIG. 10(a) is an enlarged view of a recessed portion 4001 for wiring according to the fourth embodiment of the present invention, and FIG. 10(b) is a partial enlarged view of the recessed portion 4001 for wiring.

[0175] As shown in FIG. 10, a recessed portion 4001 for wiring is provided at the top of the second side wall 4503R where the pattern wiring 4500 passes.

[0176] In the recessed portion for wiring 4001, protective protrusions 4002 are formed between each of the plurality of pattern wirings 4500.

[0177] In this respect, the recessed portion 4001 for wiring in the fourteenth embodiment is similar to the recessed portion 3001 for wiring in the thirteenth embodiment.

[0178] However, the difference is that pattern wiring is formed so that it has the same potential as the pattern wiring 4500 adjacent to the wiring recess sidewall 4004, which is the sidewall of the wiring recess 4001, and the protective protrusion sidewall 4003, which is the sidewall of the protective protrusion 4002.

[0179] In this embodiment, since it is configured as described above, it is possible to further reduce the risk that the pattern wiring 4500 passing over the top of the second side wall 4503R will come into contact with other members, jigs, and the like.

[0180] As a further effect, if the pattern wiring 4500 passing over the top of the second side wall 4503R comes into contact with another member, jig, or the like, the pattern wiring 4500 may be broken.

[0181] Even in this case, the pattern wiring provided on the side wall 4004 of the recess for wiring and the side wall 4003 of the protective protrusion serves as a bypass.

[0182] The bypass ensures that the required signal is available for transmission.

[0183] Moreover, the wiring recess sidewall 4004 and the protective protrusion sidewall 4003 are formed in a shape inclined by an angle θ shown in FIG. 10(b) with respect to a plane perpendicular to the top of the second sidewall 4503R.

[0184] In this embodiment, since it is configured in this manner, it becomes easy to irradiate the wiring recess sidewall 4004 and the protective protrusion sidewall 4003 with a laser to form a pattern wiring, thereby improving productivity.

[0185] The invention of this embodiment will be outlined below.

[0186] A feature of this structure is that a pattern wiring electrically connected to the pattern wiring 4500 adjacent to the convex portion 4002 is formed on the opposing surface 4003 of the convex portions 4002 adjacent to each other.

[0187] The distance between the opposing surfaces of one of the adjacent convex portions 4002 and the opposing surface 4003 of the other convex portion that faces the opposing surface 4004 of one convex portion is characterized by increasing in the direction in which the protruding portion 503P protrudes.

[0188] The opposing surface of protrusion 503P is characterized by being wall surface 503P for mounting electronic component 501P. [Example]

[0189] Next, a pattern protection structure for a portion of a pattern 5500 of a base member 5503 of a sensor module according to a fifth embodiment of the present invention passing through a parting line 5001 will be described with reference to FIG.

[0190] FIG. 11 is an enlarged view of a parting line 5001 according to the fifth embodiment of the present invention.

[0191] The parting line 5001 is a protrusion that is unintentionally formed at a portion of the base member 5503 that corresponds to the seam of the mold used to mold the base member 5503 when the base member 5503 is molded.

[0192] The parting line 5001 is a protrusion and is therefore a location that is likely to come into contact with other members, jigs, and the like.

[0193] As shown in FIG. 11, when a pattern wiring 5500 passes through a parting line 5001, there is a risk that the portion passing through the parting line 5001 may come into contact with other members, jigs, etc., and be broken.

[0194] Therefore, in the present invention, protective projections 5002 are disposed on both sides of the portion of pattern wiring 5500 that passes through parting line 5001 .

[0195] The protective protrusion 5002 makes it even more difficult for the pattern wiring 5500 passing through the parting line 5001 to come into contact with other members, jigs, etc., thereby reducing the risk of the pattern wiring 5500 being broken.

[0196] The invention of this embodiment will be outlined below.

[0197] The protruding portion 5001 is characterized as a parting line 5001 . [Example]

[0198] Next, a sensor module according to a sixth embodiment of the present invention will be described with reference to FIG.

[0199] The only difference between Example 1 and this example is the electrical connection means between the sensor module and other components, so in this example, only the differences between the sensor module 6508 of Example 16 and the sensor module of Example 1 will be described.

[0200] 12(a) is an external perspective view of the sensor module 6508, and FIG. 12(b) is an enlarged perspective view of the main part of the connection intermediary member 6600. FIG.

[0201] FIG. 12C is a perspective view of the sensor module 6508 and the connection intermediary member 6600 in a state in which the sensor module 6508 and the connection intermediary member 6600 are electrically connected to each other.

[0202] 12(b) and 12(c), the shape of the connection intermediary member 6600 is simplified, and only the parts necessary for explanation are shown, with the other parts omitted for ease of understanding.

[0203] In addition, in FIG. 22, pattern wiring is omitted except for portions necessary for explanation in order to facilitate understanding.

[0204] In the first embodiment, an example has been described in which the sensor module 508 and the system control unit 307 are configured to be able to perform various necessary communications via the flexible substrate 502F.

[0205] Furthermore, terminal portion 502D of flexible substrate 502F is connected to connector 502C of sensor module 508, and terminal portion 502E is electrically connected to a connector that forms part of the path to system control unit 307.

[0206] This allows the sensor module 508 and the system control unit 307 to perform various necessary communications via the flexible substrate 502F.

[0207] In other words, the flexible substrate 502F is an example of a connection intermediary member that intermediates the electrical connection from the sensor module 508 to the system control unit 307.

[0208] The flexible substrate 502F was electrically connected to the sensor module 508 via the connector 502C.

[0209] In this embodiment, the connection intermediary member 6600 is a member that forms part of the path of electrical communication between the sensor module 6508 and the system control unit 307 .

[0210] The connection intermediary member 6600 electrically connects the sensor module 6508 and the connector 502C by a means different from that of the connector 502C.

[0211] This embodiment is characterized by the electrical connection means between the connection intermediary member 6600 and the sensor module 6508, so the following description will focus on this point.

[0212] The sensor module 6508 has, on the base member 6002, a pitch direction detection gyro sensor 6004P, a roll direction detection gyro sensor 6004R, and a yaw direction detection gyro sensor (not shown).

[0213] Sensors 6004P and 6004R and a gyro sensor for detecting the yaw direction (not shown) are mounted on the first side wall 6005P, the second side wall 6005R and the main surface 6003, respectively.

[0214] Referring to FIG. 12( a ), an electrical connection portion 6001 is formed on a main surface 6003 of a base member 6002 as a part of an electrical connection means between a connection intermediary member 6600 and a sensor module 6508 .

[0215] The electrical connection portion 6001 is composed of an electrical connection recess 6501, which is a cubic recess, and a plurality of signal connection contacts 6502, power connection contacts 6503, and ground connection contacts 6504 formed on the bottom surface of the electrical connection recess 6501.

[0216] The signal connection contacts 6502 are connected to pattern wiring for electrical communication with electronic elements such as a gyro sensor mounted on the base member.

[0217] The power supply connection contact 6503 is connected to a wiring pattern that supplies power to electronic elements such as a gyro sensor.

[0218] The ground connection contact 6504 is connected to the pattern wiring of the reference potential of the sensor module 6508 .

[0219] The connection intermediary member 6600 has pattern wiring formed directly on it by MID technology, similar to the base member 503 of the first embodiment.

[0220] Referring to FIG. 12(b), the connection intermediary member 6600 is formed with an electrical connection convex portion 6601, which is a cubic convex portion that serves as part of the electrical connection means between the connection intermediary member 6600 and the sensor module 6508.

[0221] Furthermore, on the top surface of the electrical connection convex portion 6601, a plurality of signal connection contact protrusions 6602, power connection contact protrusions 6603, and ground connection contact protrusions 6604 are formed.

[0222] The plurality of signal connection contact protrusions 6602 are connected to pattern wiring for transmitting signals connected to the system control unit 307 .

[0223] The power supply connection contact protrusion 6603 is connected to a pattern wiring that is connected to the power supply control unit 313 , and the ground connection contact protrusion 6604 is connected to a pattern wiring that is connected to the reference potential of the system control unit 307 .

[0224] Here, the electrical connection convex portion 6601 formed on the connection intermediary member 6600 is configured to be lightly pressed into the electrical connection concave portion 6501 when inserted into the electrical connection concave portion 6501 formed in the base member 6002 (see Figure 12 (c)).

[0225] In addition, when the electrical connection convex portion 6601 is inserted into the electrical connection concave portion 6501, the corresponding plurality of signal connection contacts 6502 and the corresponding plurality of signal connection contact protrusions 6602 are configured to face each other.

[0226] Furthermore, the power supply connection contact 6503 and the power supply connection contact protrusion 6603 are also configured to face each other.

[0227] Furthermore, the ground connection contact 6504 and the ground connection contact protrusion 6604 are also configured to face each other.

[0228] Furthermore, the electrical connection convex portion 6601 is inserted into the electrical connection concave portion 6501 .

[0229] In this way, in the direction of inserting the electrical connection convex portion 6601 into the electrical connection concave portion 6501, the multiple signal connection contact protrusions 6602 are configured to abut against and come into contact with the multiple signal connection contacts 6502.

[0230] At this time, the power supply connection contact protrusion 6603 and the ground connection contact protrusion 6604 are configured to abut against and come into contact with the power supply connection contacts 6503 and the ground connection contacts 6504, respectively.

[0231] That is, in the state where the electrical connection convex portion 6601 is inserted into the electrical connection concave portion 6501 as shown in FIG. 12(c), the electrical connection convex portion 6601 is fixed to the electrical connection concave portion 6501 by light press-fitting.

[0232] At the same time, electrical connections are established between the multiple signal connecting contact protrusions 6602 and the multiple signal connecting contacts 6502, between the power supply connecting contact protrusions 6603 and the power supply connecting contacts 6503, and between the ground connecting contact protrusions 6604 and the ground connecting contacts 6504.

[0233] The above is a description of the electrical connection means between the connection intermediary member 6600 and the sensor module 6508 in this embodiment.

[0234] Compared to the first embodiment in which the connector 502C is used as the electrical connection means, the electrical connection means of this embodiment is advantageous in terms of cost since the connector 502C is not used.

[0235] Furthermore, inserting the electrical connection convex portion 6601 into the electrical connection concave portion 6501 has the advantage of being easier to work with than inserting the flexible substrate 502F into the connector 502C.

[0236] The invention of this embodiment will be outlined below.

[0237] The first wiring component 6002 is a wiring component in which pattern wiring is formed directly on a first base member 6002, 6600 which is an injection molded component.

[0238] The second wiring component 6600 is a wiring component in which pattern wiring is formed directly on second base members 6002, 6600 which are injection molded components.

[0239] This is a structure in which a first wiring component 6002 and a second wiring component 6600 are electrically connected.

[0240] A recess 6501 is formed in the first wiring component 6002 .

[0241] A second wiring component 6600 is formed with a convex shape 6601 that corresponds to the concave shape 6501 .

[0242] A first electrode 6502 is formed directly on the bottom surface of the recessed shape 6501 by pattern wiring.

[0243] A second electrode 6602 is formed directly on the upper surface of the convex shape 6601 by pattern wiring.

[0244] The first electrode 6502 and the second electrode 6602 are in contact with each other, thereby establishing an electrical connection.

[0245] At least one of the first electrode 6502 and the second electrode 6602 has a protruding shape.

[0246] The land is a flat surface that does not protrude, while the bump protrudes. This makes the contact between the land and the bump strong and improves the electrical connection. Both the first electrode 6502 and the second electrode 6602 may be protruding parts. [Example]

[0247] Next, a sensor module according to a seventh embodiment of the present invention will be described with reference to FIG.

[0248] This embodiment is characterized by the electrical connection means between the sensor module and other members, similar to the sixth embodiment.

[0249] Therefore, in this embodiment, only the differences between the sensor module 7510 and the connection intermediate member 7600 of the seventeenth embodiment and the sensor module 6508 and the connection intermediate member 6600 of the seventh embodiment will be described.

[0254] In addition, in FIG. 13, pattern wiring is omitted except for portions necessary for explanation in order to facilitate understanding.

[0255] In this embodiment, the connection intermediary member 7600 is a member that forms part of the electrical communication path between the sensor module 7510 and the system control unit 307 .

[0256] The connection intermediary member 7600 electrically connects the sensor module 7510 and the connector 502C by a means different from that of the connector 502C.

[0257] The sensor module 7510 has, on the base member 7002, a gyro sensor 7004P for detecting a pitch direction, a gyro sensor 7004R for detecting a roll direction, and a gyro sensor (not shown) for detecting a yaw direction.

[0258] A sensor 7004P, a sensor 7004R, and a gyro sensor for detecting the yaw direction (not shown) are mounted on the first side wall 7005P, the second side wall 7005R, and the main surface 7003, respectively.

[0259] Referring to FIG. 13( a ), an electrical connection portion 7001 is formed on a main surface 7003 of a base member 7002 as part of an electrical connection means between a connection intermediary member 7600 and a sensor module 7510 .

[0260] The electrical connection portion 7001 includes an electrical connection recess 7501 which is a cubic recess, and a plurality of signal connection contacts 7502 formed on the bottom surface of the electrical connection recess 7501 .

[0261] The signal connection contacts 7502 are connected to pattern wiring for electrical communication with electronic elements such as a gyro sensor mounted on the base member.

[0262] The electrical connection portion 7001 further includes a first locking portion 7503 and a second locking portion 7504 .

[0263] The first locking portion 7503 and the second locking portion 7504 are composed of pillars 7505 and 7507 standing on either side of the electrical connection recess 7501, and claws 7506 and 7508 provided on the electrical connection recess 7501 side from the respective tips of pillars 7505 and 7507.

[0264] Here, a pattern is formed on the claw 7506 of the first locking portion 7503, and the pattern formed on the claw 7506 is connected to a wiring pattern that supplies power to an electronic element such as a gyro sensor.

[0265] On the other hand, a pattern is formed on the claw 7508 of the second locking portion 7504 , and the pattern formed on the claw 7508 is connected to the pattern wiring of the reference potential of the sensor module 7510 .

[0266] The connection intermediary member 7600 has pattern wiring formed directly on it by MID technology, similar to the base member 503 of the first embodiment.

[0267] Referring to FIG. 13(b), the connection intermediary member 7600 is formed with an electrical connection convex portion 7601, which is a cubic convex portion that serves as part of the electrical connection means between the connection intermediary member 7600 and the sensor module 7510.

[0268] Furthermore, a plurality of signal connection contact projections 7602 are formed on the top surface of the electrical connection projection 7601 .

[0269] The plurality of signal connection contact protrusions 7602 are connected to pattern wiring for transmitting signals connected to the system control unit 307 .

[0270] The connection intermediary member 7600 has a first locked portion 7603 on one side thereof and a second locked portion 7604 on the other side thereof.

[0271] The first locked portion 7603 has a shape in which a part of the connection-intermediating member 7600 is recessed, and patterns are formed on each surface that constitutes the first locked portion 7603.

[0272] The patterns formed on each surface constituting the first locked portion 7603 are connected to pattern wiring that is connected to the power supply control unit 313 .

[0273] The second locked portion 7604 has a shape in which a part of the connection-intermediating member 7600 is recessed, and patterns are formed on each surface that constitutes the second locked portion 7604.

[0274] The patterns formed on each surface constituting the second locked portion 7604 are connected to pattern wiring that is connected to the reference potential of the system control unit 307 .

[0275] Here, please refer to FIG. 13(d).

[0276] The electrical connection convex portion 7601 formed on the connection intermediary member 7600 is configured to be lightly pressed into the electrical connection concave portion 7501 when inserted into the electrical connection concave portion 7501 formed on the base member 7002.

[0277] Furthermore, when the electrical connection convex portion 7601 is inserted into the electrical connection concave portion 7501, the corresponding plurality of signal connection contacts 7502 and the corresponding plurality of signal connection contact protrusions 7602 are configured to face each other.

[0278] Furthermore, the electrical connection convex portion 7601 is inserted into the electrical connection concave portion 7501 .

[0279] In this way, in the direction of inserting the electrical connection convex portion 7601 into the electrical connection concave portion 7501, the multiple signal connection contact protrusions 7602 are configured to abut against and come into contact with the multiple signal connection contacts 7502.

[0280] That is, in the state where the electrical connection convex portion 7601 is inserted into the electrical connection concave portion 7501 as shown in FIG. 13(d), the electrical connection convex portion 7601 is fixed to the electrical connection concave portion 7501 by light press-fitting.

[0281] At the same time, electrical connections are established between the plurality of signal connecting contact protrusions 7602 and the plurality of signal connecting contacts 7502 .

[0282] The distance between the tip of the claw 7506 and the tip of the claw 7508 is formed to be slightly smaller than the width of the portion of the connection-intermediating member 7600 where the electrical connection protrusion 7601 is provided.

[0283] The distance between the columns 7506 and 7507 is set slightly larger than the width of the portion of the connection-intermediating member 7600 where the electrical connection protrusion 7601 is provided.

[0284] The first locked portion 7603 is configured so that the claw 7506 can enter, and the second locked portion 7604 is configured so that the claw 7508 can enter.

[0285] Therefore, the electrical connection convex portion 7601 is inserted into the electrical connection concave portion 7501 .

[0286] At this time, the claw 7506 of the first locking portion 7503 is pressed by the connection intermediary member 7600 , causing the pillar 7505 to elastically deform in a direction away from the connection intermediary member 7600 .

[0287] Then, the electrical connection convex portion 7601 is inserted into the electrical connection concave portion 7501 until the plurality of signal connection contact protrusions 7602 abut against and come into contact with the plurality of signal connection contacts 7502 .

[0288] Therefore, the positions of the claw 7506 and the first locked portion 7603 are aligned, the elastic deformation of the pillar 7505 is released, and the claw 7506 enters the first locked portion 7603 .

[0289] Furthermore, when the electrical connection convex portion 7601 is inserted into the electrical connection concave portion 7501 , the claw 7508 of the second locking portion 7504 is pressed by the connection intermediary member 7600 , causing the pillar 7507 to elastically deform in a direction away from the connection intermediary member 7600 .

[0290] Then, the electrical connection convex portion 7601 is inserted into the electrical connection concave portion 7501 until the plurality of signal connection contact protrusions 7602 abut against and come into contact with the plurality of signal connection contacts 7502 .

[0291] Therefore, the positions of the claw 7507 and the second locked portion 7604 are aligned, the elastic deformation of the pillar 7507 is released, and the claw 7508 enters the second locked portion 7604 .

[0292] Among the surfaces constituting the first locking portion 7503, the surface on the electrical connection convex portion 7601 side in the direction of inserting the electrical connection convex portion 7601 into the electrical connection concave portion 7501 comes into contact with the claw 7506.

[0293] Of the surfaces constituting the second locking portion 7504 , the surface on the electrical connection convex portion 7601 side comes into contact with the claw 7508 in the direction in which the electrical connection convex portion 7601 is inserted into the electrical connection concave portion 7501 .

[0294] This reinforces the fixation between the base member 7002 and the connection intermediary member 7600 when the electrical connection convex portion 7601 is fitted into the electrical connection concave portion 7501 .

[0295] Furthermore, the pattern provided on the claw 7506 and the pattern provided on the first locked portion 7603 come into contact with each other.

[0296] This establishes an electrical connection between the base member 7002 and the connection intermediary member 7600 for transmitting power.

[0297] Furthermore, the pattern provided on the claw 7508 and the pattern provided on the second locked portion 7604 come into contact with each other.

[0298] As a result, an electrical connection for transmitting the reference potential between the base member 7002 and the connection intermediary member 7600 is established.

[0299] The above is a description of the electrical connection means between the connection intermediary member 7600 and the sensor module 7510 of this embodiment.

[0300] Compared to the electrical connection means of Example 6, the electrical connection means of this example reinforces the fixation between the base member 7002 and the connection intermediary member 7600 when the electrical connection convex portion 7601 is mated with the electrical connection concave portion 7501.

[0301] The first locking portion 7503, the second locking portion 7504, the first locked portion 7603, and the second locked portion 7604 function to reinforce the fixation between the base member 7002 and the connection intermediary member 7600 when the electrical connection convex portion 7601 is fitted into the electrical connection concave portion 7501.

[0302] Furthermore, the resistance value should be relatively small, and the contact area of ​​the electrical connection between the power supply and the reference potential can be increased to reduce the contact resistance.

[0303] Furthermore, since there is no need to arrange power connection contacts and ground connection contacts on the bottom surface of the electrical connection recess 6501, it becomes easier to ensure a pattern wiring area around the signal connection contacts 7502.

[0304] Furthermore, since there is no need to arrange the power supply connection contact protrusions and the ground connection contact protrusions on the top surface of the electrical connection convex portion 6601, it becomes easier to ensure a pattern wiring area around the signal connection contact protrusions 7602.

[0305] The invention of this embodiment will be outlined below.

[0306] The first wiring component 7002 is formed with latching portions 7503 and 7504 .

[0307] The second wiring component 7600 has latched portions 7603 and 7604 formed thereon.

[0308] The locking portions (7503, 7504) are locked by the locked portions (7603, 7604), whereby the first wiring component 7002 and the second wiring component 7600 are mechanically fixed to each other.

[0309] A feature of this structure is that the pattern wiring formed on the locking portions 7503 and 7504 comes into contact with the pattern wiring formed on the locked portions 7603 and 7604, thereby establishing an electrical connection.

[0310] The pattern wiring formed on the locking portions 7503 and 7504 and the pattern wiring formed on the locked portions 7603 and 7604 are characterized by being electrically connected to a reference potential or a power supply. [Example]

[0311] Next, a sensor module according to an eighth embodiment of the present invention will be described with reference to FIG.

[0312] This embodiment is a modification of the electrical connection means between the sensor module and other members described in the seventh embodiment.

[0313] Therefore, in this embodiment, only the differences between the sensor module 8510 and the connection intermediate member 8600 of the eighteenth embodiment and the sensor module 7510 and the connection intermediate member 7600 of the seventeenth embodiment will be described.

[0314] 14(a) is an external perspective view of the sensor module 8510, and FIG. 14(b) is an enlarged perspective view of the main part of the connection intermediary member 8600. FIG.

[0315] FIG. 14(c) is an enlarged perspective view of the essential parts of the connection intermediary member 8600, seen from a different angle than that of FIG. 24(b).

[0316] 14(b) and 14(c), the shape of the connection intermediary member 8600 is simplified, and only the parts necessary for explanation are shown, with other parts omitted for ease of understanding.

[0317] In addition, in FIG. 14, pattern wiring is omitted except for portions necessary for explanation in order to facilitate understanding.

[0318] In this embodiment, the connection intermediary member 8600 is a member that forms part of the path of electrical communication between the sensor module 8510 and the system control unit 307 .

[0319] The connection intermediary member 8600 electrically connects the sensor module 8510 and the connector 502C by a means different from that of the connector 502C.

[0320] The sensor module 8510 has, on the base member 8002, a pitch direction detection gyro sensor 8004P, a roll direction detection gyro sensor (not shown), and a yaw direction detection gyro sensor (not shown).

[0321] A sensor 8004P, a roll direction detection gyro sensor (not shown), and a yaw direction detection gyro sensor (not shown) are mounted on the first side wall 8005P, the second side wall 8005R, and the main surface 8003, respectively.

[0322] Referring to FIG. 14(a), an electrical connection portion 8001 is formed on a main surface 8003 of a base member 8002 as a part of an electrical connection means between a connection intermediary member 8600 and a sensor module 8510.

[0323] The electrical connection portion 8001 includes an electrical connection recess 8501 which is a cubic recess, and a plurality of signal connection contacts 8502 formed on the bottom surface of the electrical connection recess 8501 .

[0324] The signal connection contacts 8502 are connected to pattern wiring for electrical communication with electronic elements such as a gyro sensor mounted on the base member.

[0325] A pattern is formed on part or all of the four surfaces 8509 other than the bottom surface of the electrical connection recess 8501 .

[0326] The patterns provided on some or all of the four surfaces 8509 other than the bottom surface of the electrical connection recess 8501 are connected to the pattern wiring of the reference potential of the sensor module 8510 .

[0327] The electrical connection portion 8001 further includes a first locking portion 8503 and a second locking portion 8504 .

[0328] The first locking portion 8503 and the second locking portion 8504 are composed of pillars 8505 and 8507 standing on either side of the electrical connection recess 8501, and claws 8506 and 8508 provided on the electrical connection recess 8501 side from the respective tips of the pillars 8505 and 8507.

[0329] Here, a pattern is formed on the claw 8506 of the first locking portion 8503, and the pattern formed on the claw 8506 is connected to a wiring pattern that supplies power to an electronic element such as a gyro sensor.

[0330] On the other hand, a pattern is formed on the claw 8508 of the second locking portion 8504 , and the pattern formed on the claw 8508 is connected to the pattern wiring of the reference potential of the sensor module 8510 .

[0331] The connection intermediary member 8600 has pattern wiring formed directly on it by MID technology, similar to the base member 503 of the first embodiment.

[0332] Referring to FIG. 14(b), the connection intermediary member 8600 is formed with an electrical connection convex portion 8601, which is a cubic convex portion that serves as part of the electrical connection means between the connection intermediary member 8600 and the sensor module 8510.

[0333] Furthermore, a plurality of signal connection contact projections 8602 are formed on the top surface of the electrical connection projection 8601 .

[0334] The plurality of signal connection contact protrusions 8602 are connected to pattern wiring for transmitting signals connected to the system control unit 307 .

[0335] Four electrical connection protrusion sidewall projections 8605 are formed on the side surface of the electrical connection protrusion 8601 .

[0336] A pattern is formed on the electrical connection convex side wall projection 8605 , and the pattern formed on the electrical connection convex side wall projection 8605 is connected to the pattern wiring of the reference potential of the system control unit 307 .

[0337] The connection intermediary member 8600 has a first locked portion 8603 on one side thereof and a second locked portion 8604 on the other side thereof.

[0338] The first locked portion 8603 has a shape in which a part of the connection-intermediating member 8600 is recessed, and patterns are formed on each surface that constitutes the first locked portion 8603.

[0339] The patterns formed on each surface constituting the first locked portion 8603 are connected to pattern wiring that is connected to the power supply control unit 313 .

[0340] The second locked portion 8604 has a shape in which a part of the connection-intermediating member 8600 is recessed, and patterns are formed on each surface that constitutes the second locked portion 8604.

[0341] The patterns formed on each surface constituting the second locked portion 8604 are connected to pattern wiring that is connected to the reference potential of the system control unit 307 .

[0342] Here, the electrical connection convex portion 8601 formed on the connection intermediary member 8600 is configured to be lightly pressed into the electrical connection concave portion 8501 when inserted into the electrical connection concave portion 8501 formed in the base member 8002 (see Figure 13 (d)).

[0343] In addition, when the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501, the corresponding plurality of signal connection contacts 8502 and the corresponding plurality of signal connection contact protrusions 8602 are configured to face each other.

[0344] Furthermore, the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501 .

[0345] Therefore, in the direction of inserting the electrical connection convex portion 8601 into the electrical connection concave portion 8501, the multiple signal connection contact protrusions 8602 are configured to abut against and come into contact with the multiple signal connection contacts 8502.

[0346] That is, in the state where the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501 as shown in FIG. 13(d), the electrical connection convex portion 8601 is fixed to the electrical connection concave portion 8501 by light press-fitting.

[0347] At the same time, electrical connections are established between the plurality of signal connecting contact protrusions 8602 and the plurality of signal connecting contacts 8502 .

[0348] Furthermore, when the electrical connection convex portion 8601 is inserted into the electrical connection recess 8501, the electrical connection convex portion side wall protrusion 8605 is positioned so as to abut against the portion on which the pattern is formed on the four surfaces 8509 other than the bottom surface of the electrical connection recess 8501.

[0349] Therefore, when the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501, an electrical connection is established between the pattern formed on the electrical connection convex portion side wall protrusion 8605 and the pattern formed on the four surfaces 8509 other than the bottom surface of the electrical connection concave portion 8501.

[0350] The distance between the tip of the claw 8506 and the tip of the claw 8508 is formed to be slightly smaller than the width of the portion of the connection-intermediating member 8600 where the electrical connection protrusion 8601 is provided.

[0351] The distance between the columns 8506 and 8507 is set slightly larger than the width of the portion of the connection-intermediating member 8600 where the electrical connection protrusion 8601 is provided.

[0352] The first locked portion 8603 is configured so that the claw 8506 can enter, and the second locked portion 8604 is configured so that the claw 8508 can enter.

[0353] Therefore, when the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501 , the claw 8506 of the first locking portion 8503 is pressed by the connection intermediary member 8600 , causing the pillar 8505 to elastically deform in a direction away from the connection intermediary member 8600 .

[0354] Then, the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501 until the plurality of signal connection contact protrusions 8602 abut against and come into contact with the plurality of signal connection contacts 8502 .

[0355] Therefore, the positions of the claw 8506 and the first locked portion 8603 are aligned, the elastic deformation of the pillar 8505 is released, and the claw 8506 enters the first locked portion 8603 .

[0356] Furthermore, when the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501 , the claw 8508 of the second locking portion 8504 is pressed by the connection intermediary member 8600 , causing the pillar 8507 to elastically deform in a direction away from the connection intermediary member 8600 .

[0357] Then, the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501 until the plurality of signal connection contact protrusions 8602 abut against and come into contact with the plurality of signal connection contacts 8502 .

[0358] Therefore, the positions of the claw 8507 and the second locked portion 8604 are aligned, the elastic deformation of the pillar 8507 is released, and the claw 8508 enters the second locked portion 8604 .

[0359] Among the surfaces constituting the first locking portion 8503, the surface on the electrical connection convex portion 8601 side comes into contact with the claw 8506 in the direction in which the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501.

[0360] Among the surfaces constituting the second locking portion 8504, the surface on the electrical connection convex portion 8601 side comes into contact with the claw 8508 in the direction in which the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501.

[0361] This reinforces the fixation between the base member 8002 and the connection intermediary member 8600 when the electrical connection convex portion 8601 is fitted into the electrical connection concave portion 8501 .

[0362] Furthermore, when the pattern on the claw 8506 comes into contact with the pattern on the first engaged portion 8603, an electrical connection is established for transmitting power between the base member 8002 and the connection intermediary member 8600.

[0363] Furthermore, when the pattern provided on the claw 8508 comes into contact with the pattern provided on the second engaged portion 8604, an electrical connection is established to transmit a reference potential between the base member 8002 and the connection intermediary member 8600.

[0364] The above is a description of the electrical connection means between the connection intermediary member 8600 and the sensor module 8510 of this embodiment.

[0365] In the electrical connection means of this embodiment, the pattern formed on the electrical connection convex side wall projection 8605 is electrically connected to the pattern formed on the four surfaces 8509 other than the bottom surface of the electrical connection concave portion 8501.

[0366] Therefore, the electrical connection of the reference potential between the connection intermediary member 8600 and the sensor module 8510 becomes stronger.

[0367] Furthermore, the connection between the signal connection contact protrusion 8602 and the signal connection contact 8502 generally has the risk of generating unnecessary radiation noise.

[0368] However, since a pattern connected to the reference potential is provided on at least a part of the four surfaces 8509 other than the bottom surface of the electrical connection recess 8501, leakage of unnecessary radiation noise from the electrical connection recess 8501 can be suppressed.

[0369] Furthermore, when hot-plugging is to be achieved with this electrical connection means, the electrical connection convex portion 8601 is inserted into the electrical connection concave portion 8501. In this case, it is desirable to configure the structure so that the electrical connection between the pattern formed on the electrical connection convex side wall protrusion 8605 and the pattern formed on the electrical connection concave portion 8501 is established faster than other electrical connections.

[0370] The invention of this embodiment will be outlined below.

[0371] A pattern wiring is formed on a side surface 8509 of the recessed shape 8501 .

[0372] A protruding third electrode 8603 is formed directly on the side surface of the convex shape 8601 by pattern wiring.

[0373] A characteristic feature of this structure is that the pattern wiring formed on the side surface 8509 of the recessed shape 8501 and the third electrode 8603 come into contact with each other, thereby establishing an electrical connection.

[0374] The pattern wiring formed on the side surface 8509 of the recessed shape 8501 so as to surround the first electrode is characterized by being electrically connected to a reference potential.

[0375] The third electrode is a bump having a protruding shape. [Example]

[0376] Next, a sensor module according to an eighth embodiment of the present invention will be described with reference to FIG.

[0377] This embodiment is a modification of the electrical connection means between the sensor module and other members described in the sixth embodiment.

[0378] Therefore, in this embodiment, only the differences between the base member 9002 and the connection intermediate member 9600 constituting the sensor module of the ninth embodiment and the sensor module 6508 and the connection intermediate member 6600 of the sixth embodiment will be described.

[0379] Figure 15(a) is an enlarged oblique view of the main parts of the base member 9002, Figure 15(b) is an enlarged oblique view of the main parts of the connection intermediary member 9600, and Figure 14(c) is an enlarged cross-sectional view of the main parts when the base member 9002 and the connection intermediary member 9600 are connected.

[0380] In FIG. 15, pattern wiring is omitted except for portions necessary for explanation in order to facilitate understanding.

[0381] In this embodiment, the connection intermediary member 9600 is a member that forms part of the electrical communication path between the base member 9002 and the system control unit 307 .

[0382] The connection intermediary member 9600 electrically connects the base member 9002 and the connector 502C by a means different from that of the connector 502C.

[0383] Similar to the base member 503 of the first embodiment, pattern wiring is directly formed on the base member 9002 by MID technology.

[0384] Referring to FIG. 15(a), an electrical connection portion 9001 is formed on a base member 9002 as a part of an electrical connection means between a connection intermediary member 9600 and the base member 9002.

[0385] The electrical connection portion 9001 is made up of an electrical connection recess 9501 which is a cubic recess, and linear grooves 9503 provided on each of two opposing surfaces of the electrical connection recess 9501 .

[0386] A plurality of signal connection patterns 9502 are formed in the linear groove 9503 at predetermined intervals along the longitudinal direction thereof.

[0387] The connection intermediary member 9600 has pattern wiring formed directly on it by MID technology, similar to the base member 503 of the first embodiment.

[0388] Referring to Figure 15(b), the connection intermediary member 9600 is formed with electrical connection convex portions 9601, which are two opposing flat convex portions that serve as part of the electrical connection means between the connection intermediary member 9600 and the base member 503.

[0389] A linear protrusion 9603 is formed on each of the opposing surfaces of the two electrical connection protrusions 9601. A plurality of signal connection patterns 9602 are formed at predetermined intervals along the longitudinal direction of the linear protrusion 9603.

[0390] Here, when comparing the width of the electrical connection recess 9501 (L1 in Figure 15) with the distance between the non-facing surfaces of the two electrical connection protrusions 9601 (L2 in Figure 15), L1 and L2 are set to be equal or slightly smaller.

[0391] The linear groove 9503 has a shape that just fits the linear protrusion 9603 therein.

[0392] Therefore, the electrical connection convex portion 9601 formed on the connection intermediation member 9600 is inserted into the electrical connection concave portion 9501 formed on the base member 9002 .

[0393] Therefore, when the linear projection 9603 is pressed by the base member 9002, the two electrical connection convex portions 9601 are elastically deformed in directions in which they approach each other.

[0394] Furthermore, when the electrical connection convex portion 9601 is inserted into the electrical connection concave portion 9501, the linear protrusion 9603 is accommodated in the linear groove portion 9503, and the elastic deformation is eliminated.

[0395] Therefore, the connection intermediary member 9600 and the base member 9002 are fixed together by the action of the linear protrusions 9603 in the linear grooves 9503 (the state shown in FIG. 15(c)).

[0396] At this time, the signal connection patterns 9502 formed in the linear grooves 9503 and the signal connection patterns 9602 formed in the linear protrusions 9603 come into contact with each other in corresponding combinations.

[0397] As a result, an electrical connection between the connection intermediary member 9600 and the base member 9002 is established.

[0398] The above is the explanation of the electrical connection means between the connection intermediary member 9600 and the base member 9002 in this embodiment.

[0399] Compared to the first embodiment in which the connector 502C is used as the electrical connection means, the electrical connection means of this embodiment is advantageous in terms of cost since the connector 502C is not used.

[0400] Furthermore, inserting the electrical connection convex portion 9601 into the electrical connection concave portion 9501 has the advantage of being easier to work with than inserting the flexible substrate 502F into the connector 502C.

[0401] The invention of this embodiment will be outlined below.

[0402] The first wiring component 9002 is a wiring component in which pattern wiring is molded directly onto a base member 9002, 9600, which is a molded component.

[0403] The second wiring component 9600 is a wiring component 9600 in which pattern wiring is molded directly onto base members 9002 and 9600, which are molded components.

[0404] This is a structure in which a first wiring component 6002 and a second wiring component 6600 are electrically connected.

[0405] A recess 9501 is formed in the first wiring component 9002 .

[0406] A plurality of plate-like protrusions 9601 are formed on second wiring component 9600 .

[0407] Linear grooves 9503 are formed on the opposing side surfaces of the recess 9501 .

[0408] Linear protrusions 9603 are formed on the side surfaces of the plurality of plate-like convex portions 9601 that do not face each other.

[0409] A fourth electrode 9502 is formed directly on the bottom surface of the linear groove 9503 by pattern wiring.

[0410] A fifth electrode 9602 is formed directly on the apex of the linear protrusion by pattern wiring.

[0411] Linear groove 9503 and linear protrusion 9603 are engaged with each other, so that first wiring component 9002 and second wiring component 9600 are mechanically fixed together.

[0412] When the fourth electrode 9502 and the fifth electrode 9602 come into contact with each other, the first wiring component 9002 and the second wiring component 9600 are electrically connected to each other.

[0413] The plurality of plate-like protrusions 9601 are characterized by being two plate-like protrusions 9601 that are parallel to each other.
