JP 2001-359225 A Special table 2003-532301 gazette

  In the configuration of Patent Document 1, since the sheet metal case 54 is provided and a metal mounting member 55 is welded to the lower side thereof, the entire apparatus becomes large and a wide mounting space is required. Moreover, the assembly cost is also increased. In addition, in the case of Patent Document 2, since the leg portion to be attached to the vehicle is made of resin, there is a problem in the durability of the leg portion against the vibration of the vehicle. In other words, when attaching the vehicle electronic device to the vehicle, it is firmly tightened and fixed using a bolt or the like to withstand the vibration of the vehicle, but if the leg portion into which the bolt is inserted is a resin, There is a possibility that the leg portion is broken by the vibration.

  The present invention has been made in view of the above-described conventional problems, and its object is to reduce the weight as compared with the prior art and to ensure the durability of the legs for mounting on the vehicle. An object of the present invention is to provide an electronic device capable of reducing the assembly cost.

Is formed. “A shape that allows the electronic device to be attached to the attachment portion without the substrate being in contact with the attachment portion” means that when the substrate is attached with the attachment portion facing the attachment portion, the length of the leg portion is the same as that of the substrate. When the resin case main body faces the attachment part, the length of the leg part is the length at which the resin case main body and the attachment part do not contact or contact each other. It means that there is.

  The electronic device according to the present invention is, for example, a case where the electronic device is used by being attached to the vehicle frame as the attached portion via the leg portion, or the vehicle vibration is transmitted to the leg portion and is made of resin. More durable. Further, there is no possibility that stress when the leg portion is fastened to the attached portion with a fastener (bolt) is applied to the substrate on which the electronic component is mounted. That is, when stress is applied to the substrate when tightening with bolts, there is a risk of cracks occurring in the solder fillet used for mounting the electronic component on the substrate, but there is no such concern. Furthermore, since the metal member is insert-molded at the same time when the resin case main body is molded to form the leg portion, the assembling cost is also reduced.

  According to a second aspect of the present invention, in the first aspect of the present invention, when the mounting surface of the leg portion is attached to the attached portion, the resin case body and the substrate are attached to the attached portion. It is formed in the crank shape of the length which does not contact | abut.

The resin case body is insert-molded so as to constitute the leg portion. In this invention, compared with the case where the leg portion is provided so as to protrude from only one side wall, the electronic device can be attached to the attached portion in a stable state.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects of the present invention, the leg portions are each independently formed from a plurality of metal members that are insert-molded in the resin case body. The claw portion of each metal member is inserted into the resin case body. According to the present invention, the amount of material necessary to form the metal leg can be reduced, which is advantageous for weight reduction.

  The invention according to claim 5 is the invention according to any one of claims 1 to 3, wherein the metal member has a frame portion that is inserted into the entire side wall portion of the resin case body. The frame portion and the leg portion are integrally formed. In this invention, the reinforcing effect of the resin case body by the metal member is increased.

  According to a sixth aspect of the present invention, in the third aspect of the present invention, the metal member has a connection portion that connects a pair of leg portions that are inserted into opposing side wall portions of the resin case body. The connecting portion is inserted into a flat portion facing the open portion of the resin case body. In this invention, the strength of the resin case body can be increased as compared with the structure in which the leg portions are each independently insert-molded.

  The invention according to claim 7 is the invention according to any one of claims 1 to 6, wherein the metal member constitutes a leg portion extending along a side wall of the resin case body. The resin case body is insert-molded. Here, “extends along the side wall” means that the leg is not provided near the center of the side wall or near one end, but from one end to the other end. It means that it is provided to extend. In this invention, the rigidity of the metal legs is increased, and the vibration resistance is improved.

  According to the present invention, it is possible to reduce the weight as compared with the prior art, and it is possible to ensure the durability of the leg portion to be attached to the vehicle and reduce the assembling cost.

A first embodiment in which the present invention is embodied in an in-vehicle electronic device will be described below with reference to FIGS.
As shown in FIGS. 1A and 1B, the in-vehicle electronic device 10 includes an electronic device case 11 and a circuit board 12 as a substrate. The electronic device case 11 is formed by insert-molding a metal member 14 constituting a metal leg portion 14a on a resin case body 13. The resin case main body 13 is formed in a square box shape with one side open, and the metal member 14 is insert-molded so that the leg portions 14 a protrude from the side walls 13 a of the resin case main body 13. A plurality (two in this embodiment) of the leg portions 14a are provided.

  The leg portion is configured to protrude from the resin case body 13 in a shape that allows the vehicle-mounted electronic device 10 to be attached to the attachment portion in a state where the resin case body 13 and the circuit board 12 do not contact the attachment portion. . In this embodiment, the leg portion 14a has a portion protruding from the side wall 13a formed in a crank shape having such a length that the resin case body 13 and the circuit board 12 do not contact the attached portion, and the bottom wall 13b. It is formed so as to extend from the side toward the opening side, that is, toward the circuit board 12 side. The leg portion 14a is formed with an insertion hole 14b through which a bolt is inserted when the vehicle-mounted electronic device 10 is attached to a vehicle frame F (shown by a two-dot chain line in FIG. 2B) as an attachment portion. Yes. The leg portion 14a is set to have a height H such that when the in-vehicle electronic device 10 is attached to the frame F of the vehicle, a gap exists between the frame and the surface opposite to the mounting surface of the circuit board 12. Has been. The height H is preferably as small as possible so that the circuit board 12 does not come into contact with the frame F because the spatial space necessary for installing the in-vehicle electronic device 10 becomes smaller.

  2A and 2B, the metal member 14 is provided independently for each leg portion 14a, and a portion other than the portion protruding from the side wall 13a is formed on the side wall 13a of the resin case body 13. Embedded. A claw portion 14c bent in an L-shaped cross section is provided at a portion embedded in the side wall 13a of the metal member 14. The metal member 14 is formed of, for example, a galvanized steel plate.

  The resin case body 13 is fixed to the circuit board 12 with an adhesive with the bottom wall 13b facing upward and the end face of the side wall 13a facing the peripheral edge of the mounting surface 12a of the circuit board 12. It has become. The vehicle-mounted electronic device 10 is attached to the vehicle frame with the mounting surface 12a of the circuit board 12 facing upward, that is, with the face up.

  The circuit board 12 has an electronic component 15 mounted on the surface and an L-shaped terminal 16. The circuit board 12 is fixed to the resin case body 13 so as to cover the opening of the resin case body 13 in a state where the electronic component 15 is accommodated in the resin case body 13. That is, the circuit board 12 is attached so as to cover the open portion of the resin case body 13. As shown in FIG. 1B, the terminal 16 penetrates the hole 17 provided in the bottom wall 13 b of the resin case body 13 in a state where the circuit board 12 is fixed to the resin case body 13. , Part of which is formed to protrude from the bottom wall 13b.

  When assembling the vehicle-mounted electronic device 10 configured as described above, as shown in FIG. 1A, the circuit board 12 is approximately the same size as the circuit board 12 so that the mounting surface 12a faces upward. It mounts on the mounting part of the jig | tool which is not illustrated. Next, an adhesive is applied to the upper surface (end surface) of the side wall 13 a of the resin case body 13 or the peripheral edge of the mounting surface 12 a of the circuit board 12. Thereafter, as shown in FIG. 1A, the resin case body 13 is moved from above the circuit board 12 with the bottom wall 13b facing upward so that the holes 17 face the terminals 16 as shown in FIG. ), The resin case body 13 and the circuit board 12 are bonded together with the terminals 16 penetrating the holes 17. Since the mounting portion is approximately the same size as the circuit board 12, the resin case body 13 and the circuit board 12 are bonded together without the leg portion 14a interfering with the mounting portion. In addition, in order to ensure airtightness in and around the gap between the hole 17 and the terminal 16, a sealing agent (not shown) (for example, epoxy adhesive) is applied and cured to complete the assembly of the in-vehicle electronic device 10. To do.

  The in-vehicle electronic device 10 configured as described above is fixed via a bolt in a state where the surface opposite to the mounting surface 12a of the circuit board 12 faces the frame F of the vehicle. The bolt passes through the insertion hole 14b of the leg portion 14a and the hole formed in the frame F, and is screwed into the nut to be fastened or fixed, or passes through the insertion hole 14b and into the screw hole formed in the frame F. Screwed and tightened. Then, the in-vehicle electronic device 10 is fixed to the frame F in a state where the circuit board 12 is not in contact with the frame F. After the in-vehicle electronic device 10 is attached to the vehicle frame F, the terminal 16 and an external connector (not shown) are connected to electrically connect the electronic component 15 to an external circuit.

According to this embodiment, the following effects can be obtained.
(1) The in-vehicle electronic device 10 includes a circuit board 12 on which an electronic component 15 is mounted, and a resin case main body 13. The resin case main body 13 is formed in a box shape with one open, The circuit board 12 is attached so as to cover the open portion of the resin case body 13, and the metal member 14 constituting the leg portion 14 a is insert-molded on the resin case body 13. The leg portion 14a is formed in a crank shape having such a length that the resin case body 13 and the circuit board 12 do not come into contact with the frame F when the mounting surface thereof is attached to the frame F. Therefore, when the in-vehicle electronic device 10 is used by being attached to the vehicle frame F at the metal leg portion 14a, the stress at the time of tightening the leg portion 14a with the bolt is the circuit board on which the electronic component 15 is mounted. There is no risk of joining 12. In other words, when stress is applied to the circuit board 12 when tightening with bolts, there is a risk of cracks occurring in the solder fillet used to mount the electronic component 15 on the circuit board 12, but there is no such risk. . Further, even if the vibration of the vehicle is transmitted to the leg portion 14a, the durability is improved as compared with the case where the leg portion is made of resin. Then, when the resin case body 13 is molded, the metal member 14 is simultaneously insert-molded to form the leg portion 14a, so that the mounting member (leg portion) is welded to the sheet metal case as in Patent Document 1 of the prior art. Compared with the case of fixing with, the assembly cost is also reduced.

  (2) A plurality of leg portions 14a are provided and are configured independently of each other. Therefore, compared with the case where the plurality of leg portions 14a constitute a part of one metal member 14, the amount of material necessary for constituting the metal leg portion 14a can be reduced, and the weight can be reduced. Is advantageous.

  (3) The portion embedded in the side wall 13a of the metal member 14 is bent in an L-shaped cross section. Therefore, the anchor effect is increased and the strength is improved as compared with the case where the portion embedded in the side wall 13a is straight.

  (4) The metal member 14 is formed of a galvanized steel plate. A galvanized steel plate is preferred because it has the strength necessary for tightening with bolts and is not expensive. Furthermore, since the galvanized steel is the same material as the frame F to which the in-vehicle electronic device 10 is attached, it is preferable because the coefficient of thermal expansion is the same and the expansion and contraction due to heat is the same.

(Second Embodiment)
Next, a second embodiment embodying the present invention will be described with reference to FIGS. The second embodiment is characterized in that the in-vehicle electronic device 10 is attached to a vehicle in a state where the mounting surface 12a of the circuit board 12 faces downward (so-called face down). This is different from the first embodiment. Specifically, the shape of the leg portion 14a protruding from the resin case body 13 is different from the configuration for electrically connecting the electronic component 15 of the circuit board 12 to an external circuit. This is the same as the first embodiment. The same parts as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 3A, the resin case body 13 has a first end portion which is an external connection terminal 18 protruding from the side wall 13a, and a second end portion which is a female type at a predetermined position on the bottom wall 13b. As the tab terminal 19, an electrode (insert electrode) extending perpendicularly to the bottom wall 13b is insert-molded. For example, both ends of the female tab terminal 19 are bent into a substantially C-shaped cross section, and the male tab terminal 20 of the circuit board 12 can be inserted and connected.

  Contrary to the first embodiment, the leg portion 14a is formed to extend from the opening side of the resin case body 13 toward the bottom wall 13b. Moreover, the height H of the leg part 14a is formed so that the attachment surface of the leg part 14a and the outer surface of the bottom wall 13b are located on the same plane.

  As shown in FIG. 3 (b), the circuit board 12 is inserted into the female tab terminal 19 in place of the terminal 16 in a state where the circuit board 12 is disposed at a connection position covering the opening of the resin case body 13. A male tab terminal 20 is formed at the position to be formed.

  When assembling the in-vehicle electronic device 10 configured as described above, the resin case main body 13 is placed on the placement portion of the jig so that the bottom wall 13b is on the lower side. Next, after applying an adhesive to the upper surface of the side wall 13a or the peripheral portion of the mounting surface 12a of the circuit board 12, the circuit board 12 is face-down so that the mounting surface 12a faces down, In a state where the outer shape of the resin case main body 13 overlaps, the resin case main body 13 is moved from above the resin case main body 13 toward the resin case main body 13. During the movement, insertion of the male tab terminal 20 into the female tab terminal 19 of the resin case main body 13 is started, and the circuit board 12 is bonded to the end surface of the side wall 13a of the resin case main body 13 via an adhesive. In the state, the joining of the male tab terminal 20 and the female tab terminal 19 is completed, and the state shown in FIG. 4 is obtained.

  The on-vehicle electronic device 10 of this embodiment is fixed via a bolt in a state where the outer surface of the bottom wall 13b of the resin case body 13 is in contact with the frame F of the vehicle. Even if the outer surface of the bottom wall 13b is fixed in contact with the frame F, the circuit board 12 does not come into contact with the frame F of the vehicle, which is an attachment portion, so that the stress when tightening the leg portion 14a with the bolt is There is no fear of adding to the circuit board 12 on which the component 15 is mounted. That is, when stress is applied to the circuit board 12 when tightening with bolts, there is a risk that cracks will occur in the solder fillet used to mount the electronic component 15 on the circuit board 12, but there is no such risk. .

Therefore, according to this embodiment, the following effects can be obtained in addition to the same effects as (1) to (4) in the first embodiment.
(5) The leg portion 14a is formed so that the mounting surface is located on the same plane as the outer surface of the bottom wall 13b of the resin case body 13, and the circuit board 12 has the electronic component 15 mounted on the bottom wall 13b side. It is fixed to the resin case body 13 in a facing state, that is, in a face-down state. Therefore, since the vehicle-mounted electronic device 10 is attached to the frame F in a state where the bottom wall 13b of the resin case body 13 is in contact with the frame F, the mounting height of the vehicle-mounted electronic device 10 is lower than that of the first embodiment. It is possible to reduce the installation space of the in-vehicle electronic device 10.

  (6) Unlike the terminal 16 of the first embodiment, the male tab terminal 20 that is a connection terminal provided on the circuit board 12 does not protrude to the outside of the resin case body 13, and therefore the circuit board 12 is made of resin. After bonding to the case body 13, a configuration for sealing the gap between the terminal 16 and the hole 17 becomes unnecessary.

The embodiment is not limited to the above, and may be configured as follows, for example.
○ For example, as shown in FIG. 5 (a), one metal member 14 is formed with leg portions 14a at both ends without providing the metal members 14 constituting the leg portions 14a for each leg portion 14a. Also good. As shown in FIG. 5B, the metal member 14 is insert-molded into the resin case body 13 at the bottom wall 13b, and the leg portion 14a protrudes from the upper portion of the side wall 13a. That is, the metal member 14 has a connection portion 14d that connects a pair of leg portions 14a inserted in opposite side wall portions of the resin case main body 13, and the connection portion 14d is connected to an open portion of the resin case main body 13. It is inserted in the bottom wall 13b as an opposing plane part. In this configuration, the coupling strength between the leg portion 14a and the resin case main body 13 can be increased as compared with the configuration in which the metal leg portions 14a are insert-molded independently. Further, since the connecting portion 14d functions as a reinforcing member for the resin case body 13, the strength of the resin case body 13 can be increased.

  The metal member 14 is not limited to a flat plate, and may have a rectangular frame shape, for example, as shown in FIG. That is, the metal member 14 has a frame portion 14e inserted in the entire side wall portion of the resin case body 13, and the frame portion 14e and the leg portion 14a are integrally formed. In this case, the reinforcing effect by the metal member 14 becomes larger, and the strength of the resin case body 13 is further improved.

  ○ The thickness of the side wall 13a and the bottom wall 13b need not be the same. When the metal member 14 is inserted into the side wall 13a, the side wall 13a is thicker than the bottom wall 13b, and the metal member 14 is inserted into the bottom wall 13b. In this case, the bottom wall 13b may be thicker than the side wall 13a. In these cases, the amount of resin used can be prevented from increasing more than necessary as compared with the case where the side wall 13a and the bottom wall 13b are formed to have the same thickness.

  The leg portion 14 a is not limited to the configuration provided in the vicinity of the center portion of the side wall 13 a of the resin case body 13. For example, as shown in FIG. 6B, the metal member 14 constituting the leg portion 14 a may be insert-molded into the resin case body 13 in a state of extending along the side wall 13 a of the resin case body 13. A plurality of insertion holes 14b may be provided in each leg portion 14a. “Extending along the side wall” means that the leg portion 14a is not provided near the center of the side wall 13a or near one end, but extends from one end to the other end. It means that it is provided. In this case, the rigidity of the metal leg portion 14a is increased, and the vibration resistance is improved.

  In the case where the circuit board 12 is in a state in which the surface opposite to the mounting surface 12a is directed to the opposite side to the frame F as in the second embodiment, that is, a face-down structure, the leg portion 14a can be The height H may be set so that there is a gap between the bottom wall 13b of the resin case body 13 and the frame F when the device 10 is attached to the frame F of the vehicle.

  ○ When the circuit board 12 is in a state where the surface opposite to the mounting surface 12a is directed to the opposite side to the frame F as in the second embodiment, that is, a face-down structure, the leg portion 14a is formed in a crank shape. Instead, as shown in FIG. 7, it may be formed so as to extend perpendicularly to the side wall 13 a and the mounting surface is flush with the outer surface of the bottom wall 13 b. In this case as well, the same effect as that of the second embodiment can be obtained, and it is not necessary to process the portion to be the leg portion 14a of the metal member 14 into a cross-sectional crank shape, so that the cost can be further reduced.

The shape of the portion of the metal member 14 that is insert-molded in the resin case body 13 is not limited to the above shape, and is not particularly limited as long as it can be integrally fixed to the resin case body 13. Shape is applicable.

  O The shape of the metal member 14 may be appropriately deformed to obtain an electromagnetic shield function. For example, when unnecessary radiation noise occurs especially for a specific component mounted on the circuit board 12, an electromagnetic shield function can be secured by punching a metal plate in the region of the bottom wall 13b located above the specific component. The metal member 14 in which many small holes are formed is placed and insert-molded. In this case, the radiation of unnecessary radiation noise to the outside of the electronic device case 11 can be effectively suppressed.

  The arrangement is not limited to the arrangement in which the pair of metal legs 14a and the opposite side wall 13a of the resin case body 13 are opposed to each other. For example, two pairs may be provided on four sides or may not be a pair. As long as it can be fixed to the frame F, the number is not particularly limited, and the number is one or more. Similarly, the position is not limited. Moreover, you may provide so that the circumference | surroundings of the resin case main body 13 may be surrounded.

The number of insertion holes 14b formed in the leg portion 14a may be changed as appropriate depending on the size of the leg portion 14a.
○ Fixing to the frame F is not necessarily limited to bolts, and other fixing structures such as rivets may be adopted.

The material of the metal member 14 is not particularly limited as long as the vehicle-mounted electronic device 10 can be fixedly supported on the vehicle, but a galvanized steel plate is preferable from the viewpoint of cost, strength, and the like.
The extending position of the leg portion 14a of the metal member 14 from the resin case main body 13 is not limited to the side surface, and may be from the upper surface or the lower surface when face-down occurs.

The following technical idea (invention) can be understood from the embodiment.
