Description

  The present invention relates to a technology of the structure of an electronic control device.

  For example, in a vehicle such as an automobile, an electronic control device called an ECU (Electronic Control Unit) that controls a controlled object such as an engine or an air conditioner is mounted. Such an electronic control device is connected to the controlled object by a communication cable for transmitting a control signal and electric power.

  This will be specifically described with reference to FIG. FIG. 1 shows an electronic control device 1X and a communication cable 6X. The electronic control device 1X and the communication cable 6X are provided with connectors 4X and 5X, respectively. A connector 5X provided at one end of the communication cable 6X is connected to the connector 4X provided in the electronic control unit 1X, and the other end of the communication cable 6X is connected to the controlled object.

  In the following description, in the figure, a three-dimensional orthogonal coordinate axis (XYZ) or a two-dimensional coordinate axis (XY), (YZ) is attached, and a direction is indicated using this coordinate axis as appropriate. These coordinate axes are fixed relative to the electronic control unit 1X. For convenience of explanation, it is assumed that the X-axis direction is the depth direction, the Y-axis direction is the left-right direction, and the Z-axis direction is the up-down direction. The connector 5X provided in the communication cable 6X is referred to as a first connector 5X, and the connector 4X provided in the electronic control device 1X is referred to as a second connector 4X.

  The electronic control device 1X includes a housing 2X, a lid 3X, and an electronic substrate 7X.

  The housing 2X has a box shape having a space inside a rectangular parallelepiped, and an opening 15X is formed on a surface having the smallest area, which is one surface of the box. The housing 2X is accommodated by inserting the electronic board 7X from the opening 15X. The size of the housing 2X is large enough to cover the electronic substrate 7X substantially closely. Further, the housing 2X is provided with hooking portions 12X and 13X for fixing the housing 2X when the housing 2X is closed with the lid 3X on the opposite side surfaces in the vicinity of the opening 15X.

  The lid 3X is formed of a resin having a size that closes the opening 15X formed by the housing 2X. The cover 3X is formed with an exposure port 14X so as to expose the second connector 4X included in the electronic board 7X to the outside while the housing 2X is closed. Further, the lid 3X includes ears 10X and 11X that engage with the hooks 12X and 13X of the housing 2X at positions corresponding to the hooks 12X and 13X in a state where the housing 2X is closed.

  The electronic board 7X is a substantially rectangular plate-like body, and the second connector 4X and other electronic components are mounted on both sides.

  The second connector 4X is a connector called a pin insert having a plurality of pins, is a box shape having a space inside a rectangular parallelepiped, and one surface on the −X side of the box is open. The second connector 4X includes a plurality of pins. One end of each of the plurality of pins is fixedly connected to the end portion of the electronic substrate 7X, and the other end is a direction in which one surface of the second connector 4X is open (−X Protruding toward the side).

  The communication cable 6X includes a first connector 5X at one end. The first connector 5X is a connector called a socket insert, is a box shape having a rectangular parallelepiped, and has a size that fits in a close state in the space of the second connector 4X. The first connector 5X includes a plurality of holes that fit into the plurality of pins of the second connector 4X in a state of being accommodated in the second connector 4X.

  FIG. 2 shows a state in which the housing 2X houses the electronic board 7X, the opening 15X is closed by the lid 3X, and the ears 10X and 11X of the lid 3X are hooked and fixed to the hooks 12X and 13X. This shows an electronic control device 1X. In such a closed state, the second connector 4X mounted on the electronic board 7X is exposed from the exposure port 14X of the lid 3X, so that the communication cable 6X is attached with the lid 3X being attached to the housing 2X. Can be connected to the second connector 4X mounted on the electronic board 7X.

  FIG. 3 is a cross-sectional view at the position III-III along the XZ plane in the electronic control unit 1X of FIG. According to this cross-sectional view, the electronic control unit 1X accommodates the electronic board 7X on which the second connector 4X having the plurality of pins 8X and the other electronic components 9X are mounted in a close contact state inside the housing 2X. On the other hand, it can be seen that the second connector 4X is exposed from the exposure port 14X of the lid 3X in a state where the opening 15X is closed by the lid 3X.

  FIG. 4 is a cross-sectional view at the IV-IV position along the XZ plane of the communication cable 6X of FIG. 2 and the first connector 5X provided therein. According to this cross-sectional view, the first connector 5X is a box shape having a rectangular parallelepiped, and a plurality of holes 16X are formed that fit into the plurality of pins 8X of the second connector 4X when fitted in the second connector 4X. Has been.

  FIG. 5 is a top view of the lid 3X of FIG. 2 viewed from the + Z side. According to this top view, the lid 3X has ears 10X and 11X that engage with the hooks 12X and 13X of the housing 2X on the lateral side (+ Y side and -Y side) of the lid 3X. I understand. Moreover, it turns out that the outer side (-X side) when the cover body 3X is mounted | worn to the housing | casing 2X is a plane.

  FIG. 6 is a front view of the electronic control unit 1X of FIG. 2 as viewed from the −X side. According to this front view, the region A between the upper bottom of the opening 15X and the upper bottom of the exposure opening 14 in the lid 3X is between the lower bottom of the opening 15X and the lower bottom of the exposure opening 14. It can be seen that it is narrower than region B.

  Various components are mounted on both sides of the electronic substrate 7X, and further, the second connector 4X having the highest height from the mounting surface is mounted on one side. As shown in FIG. 3, the housing 2X of the electronic control device 1X is closed by the lid 3X in a state where the electronic substrate 7X is substantially closely covered in order to reduce the size of the electronic substrate 7X as appropriate. . For this reason, as shown in FIG. 6, the positions of the exposure port 14 </ b> X and the connector 4 </ b> X on the outer plane in the lid 3 </ b> X are shifted to the upper side from the vertical center.

  Such a technique related to the structure of the electronic control device is disclosed in Patent Document 1, for example.

  However, in the electronic control device 1X adopting the above-described structure, the first connector 5X is connected to the human hand while the first connector 5X included in the communication cable 6X and the second connector 4X included in the control device are connected. There is a possibility that the components mounted on the electronic board 7X may be damaged when being pulled out.

  That is, there is a possibility of the following. As shown in FIG. 7, in the electronic control device 1X in a state where the first connector 5X included in the communication cable 6X and the second connector 4X included in the control device are connected, a person grasps the first connector 5X and If it is pulled out straight in the direction (parallel to the -X side in FIG. 7), there is no fear, but it cannot be pulled out easily because the connection state between the first connector and the second connector is strong. In addition, the first connector 5X tends to be pulled out (roughly) in the front direction (−X side) while swinging up and down (+ Z side and −Z side in FIG. 7).

  Then, since the second connector 4X is exposed from the exposure port 14X, the fixing condition of the second connector 4X is weak and greatly shaken. The other ends of the plurality of pins 8X provided in the second connector 4X are fitted into the plurality of holes 16X of the first connector 5X, and the first connector 5X is surrounded by the second connector 4X. When the two connectors are greatly shaken, the force that shakes the first connector 5X is also transmitted to the plurality of pins 8X. As a result, a force C is applied to the other ends of the plurality of pins 8X fixedly connected to the electronic substrate 7X, and the connection points may be damaged. Further, a force D (stress) that deforms the electronic substrate 7X is also applied near the connection point of the electronic substrate 7X, and the electronic substrate 7X and other electronic components 9X mounted in the vicinity thereof may be damaged.

  As a first plan for avoiding such a problem, the second connector 4X is mounted inside the electronic substrate 7X and is housed inside the housing 2X so that the housing 2X is closed by the lid 3X. Then, only the connection surface is exposed from the exposure port 14X of the lid 3X. As a result, the second connector 4X can be fixed inside the housing, and even if the second connector 4X is pulled out roughly, it is possible to prevent the shaking and prevent damage to the second connector 4X and other electronic components 9X.

  Further, as a second plan, other electronic components 9X are mounted on the electronic board 7X away from the vicinity where the other ends of the plurality of pins 8X provided in the second connector 4X are mounted, so that other electrons due to stress are mounted. It is conceivable to prevent damage to the component 9X.

  Further, as a third plan, even if the gap is roughly pulled out by packing so as to eliminate the gap between the exposure port 14X and the second connector 4X exposed from the exposure port 14X, and firmly fixing them. It is conceivable to prevent the second connector 4X from shaking and to prevent damage to the second connector 4X and other electronic components 9X.

Utility Model Registration No. 2519155

  However, in the first proposal, since the second connector 4X is mounted inside the electronic board 7X, the mountable area of the other electronic component 9X becomes small, and the electronic board 7X has to be enlarged, and electronic control is required. When the device 1X becomes large, the cost increases, and the electronic control device 1X becomes large and heavy. Further, in the second plan, when other electronic components 9X are mounted away from each other, the electronic substrate 7X must be enlarged, and when the electronic control device 1X becomes larger, the cost increases, the electronic control device 1X increases in size and weight. It will become. Moreover, in the 3rd plan, since the 2nd connector 4 will be firmly fixed with the housing | casing 2X if the gap is packed, the noise by the 2nd connector 4 will be easy to generate | occur | produce.

  The present invention has been made in view of the above problems, and the first connected to the second connector of the electronic control device while preventing abnormal noise due to resonance without increasing the size and weight of the electronic control device. An object of the present invention is to provide a second connector mounted on an electronic board included in the electronic control device and an electronic control device that can prevent damage to other electronic components when the connector is pulled out.

  In order to solve the above-mentioned problem, the invention of claim 1 is an electronic control device, which is physically connected to a housing forming an opening in one direction and a first connector provided in a communication cable in the one direction. And a second connector surrounding the first connector in a connected state, an electronic board housed in the housing and mounted with other electronic components, one end fixed to the electronic board, and the other An end projecting into the second connector, and a connector pin that fits into a hole of the first connector in the connected state; and a flexible lid that closes the opening of the housing; The body includes an opening that exposes the second connector in the one direction, is provided at a peripheral edge of the exposure opening, and covers a part of the periphery of the second connector that is exposed from the exposure opening. It is characterized by that.

  According to a second aspect of the present invention, in the electronic control device according to the first aspect, the second connector is fixed to the electronic substrate, and the cover portion is surrounded by the exposure port. The second connector covers a direction opposite to a direction in which the second connector is fixed to the electronic board.

  According to a third aspect of the present invention, in the electronic control device according to the second aspect, the cover is fixed to the electronic substrate, the second connector of the periphery of the second connector exposed from the exposure port. It covers the direction other than the direction to be applied.

  According to a fourth aspect of the present invention, in the electronic control device according to any one of the first to second aspects, the casing is further hooked on each of two opposing side surfaces of the opening. The lid body further includes an ear portion that engages with the hook portion.

  According to invention of Claim 1 thru | or 4, when pulling out a 1st connector by the cover part which covers a part of circumference | surroundings of the 2nd connector exposed from the exposure port of a cover body, a 2nd connector and a connector pin are staggered. In this way, damage to the second connector and other electronic components on the electronic board can be prevented. Furthermore, it is possible to easily grasp the first connector connected to the second connector viewed from an uncovered portion of the cover that covers a part of the periphery of the second connector, and is necessary when the lid is detached from the housing. Does not impair the flexibility.

<Representative form>
Hereinafter, an electronic control apparatus according to an embodiment of the present invention will be described with reference to FIGS. FIG. 8 shows the electronic control device 1 and the communication cable 6 of the present embodiment. The electronic control device 1 is mounted on a vehicle such as an automobile, and is configured as an ECU (Electronic Control Unit) that controls a controlled object such as an engine or an air conditioner. The electronic control device 1 and the communication cable 6 are provided with connectors 4 and 5, respectively. A connector 5 provided at one end of the communication cable 6 is connected to the connector 4 provided in the electronic control device 1, and the other end of the communication cable 6 is connected to the controlled object.

In the following description, in the figure, a three-dimensional orthogonal coordinate axis (XYZ) or a two-dimensional coordinate axis (XY), (YZ) is attached, and a direction is indicated using this coordinate axis as appropriate. These coordinate axes are fixed relative to the electronic control unit 1. For convenience of explanation, it is assumed that the X-axis direction is the depth direction, the Y-axis direction is the left-right direction, and the Z-axis direction is the vertical direction. However, when the electronic control device 1 is actually mounted, these directions may be switched. Further, the connector 5 included in the communication cable 6 is referred to as a first connector 5, and the connector 4 included in the electronic control device 1 is referred to as a second connector 4.
(Electronic control device)
The electronic control device 1 includes a housing 2, a lid 3, and an electronic substrate 7.
(Casing)
The casing 2 is made of an insulating resin or metal and has a box shape having a space inside a rectangular parallelepiped, and an opening 15 is formed on a surface having the smallest area, which is one surface of the box. . The housing 2 is accommodated by inserting the electronic substrate 7 from the opening 15. The size of the housing 2 is large enough to cover the electronic substrate 7 substantially closely. Furthermore, the housing 2 includes hook portions 12 and 13 for fixing the housing 2 when the housing 2 is closed with the lid 3 on the side surfaces in the vicinity of the opening 15 and facing each other. The reason why the electronic substrate 7 is covered substantially closely is to reduce the size while preventing an impact from the outside of the electronic control device 1.
(Electronic substrate)
The electronic board 7 is a substantially rectangular plate having insulating properties, and the second connector 4 and other electronic components 9 are mounted on both sides.
(Secondary connector)
The second connector 4 is a connector called a pin insert having a plurality of pins, and is a box shape having a space inside a rectangular parallelepiped, and one surface on the −X side of the box is open. The second connector 4 includes a plurality of pins. One end of each of the plurality of pins is fixedly connected to the end of the electronic substrate 7, and the other end is a direction in which one surface of the second connector 4 is open (−X Protruding toward the side). The plurality of pins outputs a control signal generated by an electronic component mounted on the electronic substrate 7 to the outside of the electronic control device 1 via the connected first connector 5 and the communication cable 6, and A function of inputting a control signal transmitted from the outside via the communication cable 6 is provided.
(Lid)
The lid 3 is made of a resin having flexibility and insulation enough to close the opening 15 formed by the housing 2. The lid 3 forms an exposure opening 14 so that the second connector 4 included in the electronic board is exposed to the outside of the casing while the casing 2 is closed. The lid 3 is provided on the periphery of the exposure port 14 and forms a cover 17 that covers a part of the periphery of the second connector X4 exposed from the exposure port 14 in a state in which the housing 3 is closed. Furthermore, the lid 3 is provided with ears 10 and 11 that engage with the hooks 12 and 13 of the housing 2 at positions corresponding to the hooks 12 and 13 in the closed state.
(Cover)
The cover 17 is a direction in which the second connector 4 is fixed to the electronic substrate 7 in the periphery of the second connector 4 exposed from the exposure port 14 in a state where the cover 3 closes the housing 2 (−Z side). The direction other than the direction (+ Z side) other than the direction fixed to the electronic substrate 7 (−Z side) is covered.

  Since the width of the cover 17 from the upper bottom of the exposure opening 14 to the upper bottom of the cover 17 is narrow, the vertical width of the upper cover 17U on the upper side of the cover 17 is relatively narrow.

  This is because an electronic substrate 7 on which various components are mounted on both surfaces and the second connector 4 having the highest height from the mounting surface is fixed on one surface is formed by a housing 2 as shown in FIG. Since the cover 3 is closed in a state of being covered substantially closely so as to reduce the size as a whole while being appropriately protected, as shown in FIG. 9, the positions of the outer surfaces of the exposure port 14 and the connector 4 on the cover 3 are This is because the upper cover portion 17U becomes relatively narrow because the position is shifted upward from the vertical center.

  On the other hand, the left side cover part 17L and the right side right cover part 17R on the left side of the exposure port 14 formed in the cover body 3 of the cover part 17 have a relatively wider vertical width than the upper cover part 17U. . The left cover 17 and the right cover 17R are continuous with the upper cover 17U and are connected by the upper cover 17U.

That is, by adopting such a structure, the strength of the relatively narrow upper cover 17U in the cover 17 can be reinforced by the left and right relatively wide left cover 17 and right cover 17R. it can.
(communication cable)
The communication cable 6 includes a first connector 5 at one end. The first connector 5 is a connector called a socket insert, is a box shape having a rectangular parallelepiped, and has a size that fits in a close state in the space of the second connector 4. The first connector 5 is formed in a plurality of holes (pin holes) that fit into the plurality of pins of the second connector 4 while being accommodated in the second connector 4. The plurality of holes have functions of transmitting control signals output from the plurality of pins to the communication cable 6 and inputting control signals transmitted via the communication cable 6 to the pins.
(Structure of electronic control unit)
FIG. 9 shows the state in which the housing 2 contains the electronic substrate 7 and the lid 3 closes the opening 15, and the hooks 12 and 13 engage and fix the ears 10 and 11 of the lid 3. The electronic control device 1 in a state is shown. In such a closed state, the second connector 4 mounted on the electronic substrate 7 is exposed from the exposure port 14 of the lid 3, so that the communication cable 6 is attached with the lid 3 attached to the housing 2. 1 can be connected to the second connector 4 mounted on the electronic board 7. Further, the cover 17 can cover directions around the second connector other than the direction in which the cover 17 is fixed to the electronic substrate 7, including the direction opposite to the direction in which the cover 17 is fixed to the electronic substrate 7.

  FIG. 10 is a cross-sectional view at the VII-VII position along the XZ plane in the electronic control unit 1 of FIG. According to this cross-sectional view, the electronic control device 1 has an opening portion while accommodating an electronic board 7 on which another electronic component 9 and a second connector 4 having a plurality of pins 8 are mounted in a substantially closely contacted state. It can be seen that the second connector 4 is exposed from the exposure port 14 of the lid 3 in a state where 15 is closed by the lid 3.

  Furthermore, the cover 3 covers the direction opposite to the direction in which the cover 17 of the second connector 4 exposed from the exposure port 14 is fixed to the electronic substrate 7 in the periphery of the second connector. I can see that

  The structure of the communication cable 6 and the first connector 4 included in the communication cable 6 is the same as that shown in FIG. 4, and will be described with reference to FIG. FIG. 4 corresponds to a cross-sectional view at the IV-IV position along the XZ plane in the communication cable 6 and the first connector 5 provided in FIG. According to FIG. 4, the first connector 5 is a box shape having a rectangular parallelepiped, and a plurality of holes (pin holes) that fit into the plurality of pins 8 of the second connector 4 when fitted in the second connector 4. It can be seen that 16 is formed.

  FIG. 11 is a top view of the lid 3 of FIG. 8 as viewed from the + Z side. According to this top view, the lid 3 is provided with ears 10 and 11 that engage with the hooking portions 12 and 13 of the housing 2 on the lateral side (+ Y side and −Y side) of the lid 3. I understand.

  In addition, the lid 3 has a shape in which the outer surface (the surface on the −X side) when the housing 2 is closed is raised in a trapezoidal shape with a certain range wider than the width of the exposure port 14. It can be seen that the portion where the cover 17 is not formed is substantially flat.

  FIG. 12 is a front view of the electronic control device 1 of FIG. 8 as viewed from the −X side. According to this front view, it can be seen that the width of the upper base of the cover 3 from the upper bottom of the exposure opening 14 of the cover 3 is narrow, so that the upper cover portion 17U of that portion is also narrowed. On the other hand, the left and right covers 17L and 17R of the exposure opening 14 formed in the lid 3 are wider than the upper cover 17U and are continuous with the narrow upper cover 17U. Recognize.

  Since the cover 17 of the lid 3 employs such a structure, even if a person tries to pull out the first connector 5 connected to the second connector 4 of the electronic control device 1 roughly, The upper cover portion 17U presses the second connector 4 exposed from the exposure port 14, and the left and right cover portions 17L and 17R of the exposure port 14 reinforce the press, so that the second connector 4 and the plurality of pins are staggered. This can prevent the electronic substrate 7, the second connector 4 and other electronic components 9 from being damaged.

  Moreover, since the cover part 17 of the cover body 3 surrounds the circumference | surroundings of the 2nd connector 4, it can make it difficult to receive the impact from the outside.

  In addition, the first connector 5 connected to the second connector 4 viewed from an uncovered portion (the -Z side of the second connector 4) of the cover portion 17 that covers a part of the periphery of the second connector 4 can be easily grasped. And the flexibility required when attaching / detaching the cover 3 from the housing 2 is not impaired.

  Further, by forming the cover 17 in a trapezoidal shape larger than the exposure port 14, the side surfaces of the upper and lower bases are slanted, and the lid 3 including the cover 17 formed of resin is formed. Can be manufactured with good quality. That is, when the resin is poured into such a mold of the lid 3, the side of the cover portion 17 is inclined so that the resin can easily flow in a symmetrical manner, and the resin can be formed speedily without unevenness. .

  Moreover, since the cover part 17 is formed in the cover body 3, it can suppress that the electronic substrate 7 and the housing | casing 2 are enlarged, cost can be suppressed, and the weight increase by enlargement can be suppressed.

  Further, the gap between the exposure port 14 and the second connector 4 exposed from the exposure port 14 is narrowed so that the fixing between the housing 2 and the second connector 4 is strengthened and resonance noise is generated. Can be avoided.

<Modification>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible. Other embodiments will be described below.

<Modification 1>
The cover 17 formed on the lid 3 in the above embodiment is “the second connector 4 out of the periphery of the second connector 4 exposed from the exposure port 14 in a state where the lid 3 closes the housing 2. The cover 17 covers the direction other than the direction fixed to the electronic substrate 7 including the direction opposite to the direction fixed to the electronic substrate 7. Only the upper cover portion 17U may be formed as the cover portion 17 in a narrow width to the bottom.

  Even in this case, even if a person tries to pull out the first connector 5 connected to the second connector 4 of the electronic control device 1, the upper cover portion 17 </ b> U holds the second connector 4 exposed from the exposure port 14. Therefore, the second connector 4 and the plurality of pins can be prevented from wobbling, and the electronic substrate 7, the second connector 4 and other electronic components 9 in the electronic substrate 7 can be prevented from being damaged.

  In addition, as long as the effect of this invention is produced, various things including the said modification can be considered.
