Abstract

A damper is disposed in retaining holes (41a, 41b, 41c) that pass through a supported member (1) in a through-direction, the supported member being supported by supporting members (3a, 3b, 3c, 3d). The damper includes a tubular body (61a, 61b, 61c, 61d) defining a through-hole (H1) extending in the through-direction. The tubular body is elastically deformable between a first form and a second form. The tubular body in the first form has an external shape smaller than that of the retaining hole. The tubular body in the second form has an external shape equal to or larger than that of the retaining hole.

Description

Technical Field

[0001] This disclosure relates to dampers, electronic controllers, and methods for connecting dampers. Background Technology

[0002] An example of a damper is the vibration-damping bushing disclosed in JP 2014-095441A. The vibration-damping bushing absorbs stress transmitted from the attached components to the electronic device. Summary of the Invention

[0003] Incidentally, electronic devices have brackets that define holes, and vibration-damping bushings are disposed within these holes. However, when the vibration-damping bushings are designed to be easily inserted into the holes, the retaining force between the vibration-damping bushings and the brackets may not be guaranteed.

[0004] The purpose of this disclosure is to provide an improved damper, an electronic controller, and a method for connecting the damper. Another purpose of this disclosure is to provide a damper capable of ensuring holding force. Another purpose of this disclosure is to provide an electronic controller that can be protected from stress. Another purpose of this disclosure is to provide a method for connecting a damper that simplifies the connection process.

[0005] The damper of this disclosure is disposed in a retaining hole that passes through a supported member supported by a support member in a through-direction. The damper includes a tubular body defining a through-hole extending in the through-direction. The tubular body is elastically deformable between a first form and a second form. The tubular body in the first form has an external shape smaller than that of the retaining hole. The tubular body in the second form has an external shape equal to or larger than that of the retaining hole.

[0006] According to this damper, since the damper can take the form of a first shape with an external shape smaller than that of the retaining hole, the damper can be easily inserted into the retaining hole. Furthermore, since the tubular body can be deformed into a second shape with an external shape equal to or larger than that of the retaining hole, the retaining force on the supported member can be ensured.

[0007] The electronic controller of this disclosure includes a damper, a support member, and a supported member. A tubular body in a second form is disposed in a retaining hole and presses against the inner surface of the retaining hole. The supported member is supported by the support member via the damper.

[0008] The electronic controller includes a damper. Therefore, the electronic controller can relax not only the stress applied to the supported member along the direction of the through-hole, but also the stress applied to the supported member along the intersecting directions. Thus, the electronic controller can protect the supported member from stress.

[0009] The electronic controller of this disclosure includes a support member, a damper, a supported member, and a retaining member. The damper has a tubular body that is elastically deformable and defines a through-hole. The through-hole extends through the tubular body between a first end and a second end. The supported member defines a retaining hole and is supported by the support member via the damper, which is disposed within the retaining hole. The retaining hole extends along the through-hole of the tubular body. The retaining member presses the damper against the support member to retain the damper within the supported member. The damper includes end corner surfaces. At least one of the support member or the retaining member includes an inclined surface that contacts the end corner surface of the damper, such that at least one of the support member or the retaining member is fitted into the damper. The damper uses pressure to contact the inner circumferential surface of the retaining hole to retain the supported member.

[0010] In this electronic controller, at least one of the support member and the retaining member is assembled to the damper. Therefore, the electronic controller can limit the displacement of the damper from at least one of the support member and the retaining member. Thus, in the electronic controller, compared to the case of damper displacement, the damper can be properly pressed against the inner circumferential surface of the retaining hole. Therefore, the supported member can be protected from stress.

[0011] The method for connecting the damper of this disclosure includes an insertion step of inserting a tubular body in a first form into a retaining hole and a deformation step of melting an adhesive with heat to deform the tubular body from the first form to a second form. Thereby, the tubular body is pressed against the inner surface of the retaining hole by a restoring force.

[0012] In this method, since the damper is in its first form during the insertion step, it is easy to insert the damper into the retaining hole. Then, since a deformation step is performed after the insertion step, the damper can be easily pressed against the inner surface of the retaining hole. Therefore, the connection steps of the damper can be simplified using this method.

[0013] The aspects disclosed in this specification employ different technical solutions to achieve their respective objectives. The objectives, features, and advantages disclosed in this specification will become apparent from the following detailed description and accompanying drawings. Attached Figure Description

[0041] In the following description, several embodiments for implementing this disclosure will be illustrated with reference to the accompanying drawings. In each embodiment, portions corresponding to those described in the foregoing embodiments are denoted by the same reference numerals, and redundant descriptions will be omitted in some cases. In each embodiment, when only a portion of the construction is described, the other portions of the construction may be applied with reference to the foregoing embodiments.

[0042] (First Embodiment)

[0043] First, refer to Figures 1 to 6 The structure of the electronic controller 100 is described. The electronic controller 100 includes a circuit board 1, a cover 2a, a base 3a, a damper 6a, etc. For example, the electronic controller 100 is configured to be installed in a vehicle. Therefore, the electronic controller 100 can be used as a controller for controlling in-vehicle devices. Figure 1 and 2 In the diagram, the damper 6a is simplified.

[0044] <Circuit Board>

[0045] Circuit board 1 corresponds to the supported component. Circuit board 1 includes an insulating substrate 4a, circuit elements 51 and 52, connector 53, etc. The insulating substrate 4a is made of a material such as resin or ceramic and has electrical insulating properties. The insulating substrate 4a defines a second insertion hole 41a that passes through the insulating substrate 4a along the thickness direction.

[0046] In the following text, the thickness direction of the insulating substrate 4a will be simply referred to as the thickness direction. The thickness direction is the same as the through-hole H1 of the damper 6a described later passes through the damper 6a. Furthermore, the direction intersecting the thickness direction corresponds to the intersection direction. The intersection direction is a planar direction parallel to the mounting surface on which the circuit elements 51, etc., are mounted in the insulating substrate 4a.

[0047] The insulating substrate 4a is provided with a wiring pattern 42 as part of the conductive wiring. The wiring pattern 42 is provided on the surface or inside the insulating substrate 4a. The circuit board 1 may be a multilayer board in which the wiring pattern 42 and the insulating substrate 4a are stacked on each other, or a single-layer board in which a single layer wiring pattern 42 is provided on the insulating substrate 4a, etc.

[0048] Each of the second insertion holes 41a corresponds to a retaining hole. The second insertion holes 41a are defined, for example, at the four corners of the insulating substrate 4a. Each of the second insertion holes 41a is the hole into which the second screw 202 and the damper 6a are inserted. The damper 6a is disposed in the second insertion hole 41a to contact the second insertion hole 41a using pressure. The damper 6a will be described in detail later.

[0049] In addition, such as Figure 5 and 6 As shown, the second insertion hole 41a is a through hole surrounded by an annular insertion hole surface S11. The second insertion hole 41a is a hole with an inner diameter of R21. The insertion hole surface S11 corresponds to the inner surface of the retaining hole.

[0050] Circuit elements 51 and 52 and connector 53 correspond to electronic components. Circuit elements 51 and 52 and connector 53 are mounted on insulating substrate 4a.

[0051] Each of the circuit elements 51 and 52 is, for example, a semiconductor switching element, a resistive element, a capacitor, etc. Circuit element 51 is mounted on a first surface of the insulating substrate 4a. On the other hand, circuit element 52 is mounted on a second surface of the insulating substrate 4a opposite to the first surface. More specifically, circuit elements 51 and 52 are mounted on the insulating substrate 4a by solder 51a. Furthermore, circuit elements 51 and 52 are electrically connected to wiring pattern 42 by solder 51a.

[0052] The number of circuit elements 51 and 52 is not limited to Figure 1The quantities shown are as follows. Furthermore, in this embodiment, solder is used as an example of a conductive connection component. However, the conductive connection component is not limited to solder; other components such as silver paste can also be used. The solder 51a and wiring pattern 42 can be considered as the connection portion between the electronic component and the insulating substrate 4a.

[0053] Connector 53 includes terminals 531 and a connector housing that holds the terminals 531. Connector 53 is mounted on an insulating substrate 4a, and the terminals 531 and wiring are electrically connected to each other via solder. Connector 53 provides an electrical connection between electronic controller 100 and an external device located outside electronic controller 100. The external device is another electronic controller, a device to be controlled, etc. Furthermore, connector 53 can be, for example, an interface for connecting to a communication line in a vehicle network. That is, in this embodiment, connector 53 is used as an example of an interface.

[0054] In this embodiment, as an example, a circuit board 1 equipped with connector 53 is used. However, in this disclosure, circuit board 1 may not have connector 53.

[0055] The circuit board 1 is supported by the base 3a using second screws 202. More specifically, the circuit board 1 is supported by the base 3a via the damper 6a using second screws 202. Furthermore, the circuit board 1 is supported by the base 3a using a plurality of second screws 202. In this embodiment, as an example, the circuit board 1 is supported by the base 3a using four second screws 202. Therefore, each of the second screws 202 is also referred to as a support element.

[0056] The second screw 202 may contain metal as its main component. The second screw 202 has a columnar portion 202a with male threads and a screw head 202b located at the end of the columnar portion 202a. The columnar portion 202a is inserted into the second insertion hole 41a and the through hole H1 of the damper 6a, and a portion of the columnar portion 202a is threadedly connected to the second screw hole 32 (i.e., female thread) defined in the base 3a.

[0057] The screw head 202b has a screw pressing surface S31 that contacts and presses against the end surface (here, the second surface S2) of the damper 6a. Therefore, when the second screw 202 is screwed into the second screw hole 32, the screw pressing surface S31 presses against the second surface S2 of the damper 6a. In other words, when the screw pressing surface S31 contacts the second surface S2, the second screw 202 presses against the damper 6a toward the base 3a.

[0058] In this way, the male thread of the second screw 202 engages with the female thread of the second screw hole 32, thereby supporting the circuit board 1 on the base 3a. In other words, the circuit board 1 is threadedly connected to the base 3a by the second screw 202.

[0059] <Shell>

[0060] Reference Figure 1 and 2 The following describes the housing. The housing houses the circuit board 1. The housing includes a cover 2a and a base 3a. The cover 2a and the base 3a are assembled together to define a receiving space for housing the circuit board 1. The cover 2a and the base 3a are primarily made of a metal such as aluminum. Therefore, the cover 2a and the base 3a are electrically conductive.

[0061] However, the shell is not limited to this. For example, the cover 2a and the base 3a may be mainly made of resin or the like. Furthermore, either the cover 2a or the base 3a may be made of metal as the main component.

[0062] The cover 2a is, for example, a plate-like member. A first insertion hole 21 is defined through the cover 2a in the thickness direction. For example, the first insertion hole 21 is defined at the four corners of the cover 2a. The first insertion hole 21 is the hole into which the first screw 201 is inserted.

[0063] The base 3a corresponds to the support member. The base 3a is, for example, a box-shaped member with recesses. The base 3a defines a first screw hole 31, a second screw hole 32, and a connector hole 33. The first screw hole 31, like the second screw hole 32, has a female thread. The first screw hole 31 is defined, for example, at the four corners of the base 3a. Further, the first screw hole 31 is defined, for example, in the flange of the base 3a. Moreover, the first screw hole 31 is defined at a position facing the first insertion hole 21 when the cover 2a and the base 3a are positioned facing each other.

[0064] The second screw hole 32 is defined at the location where the circuit board 1 of the base 3a is disposed. For example, the second screw hole 32 is defined facing the four corners of the circuit board 1. More specifically, the second screw hole 32 is defined in the base 34a of the base 3a. The base 34a is a protruding portion that protrudes further than the peripheral portion of the base 34a. The second screw hole 32 is defined at the location facing the second insertion hole 41a when the circuit board 1 is disposed on the base 34a. The surface of the base 34a is the base pressing surface S21 pressed by the damper 6a. However, this disclosure is not limited thereto.

[0065] The connector hole 33 is a through hole defined in the bottom of the base 3a. The connector hole 33 has an opening shape corresponding to the external shape of the connector 53. When the circuit board 1 is mounted on the pedestal 34a, the connector 53 is inserted into the connector hole 33. The connector hole 33 is not necessarily defined in the base 3a.

[0066] The first screw 201 has the same construction as the second screw 202. The cylindrical portion of the first screw 201 is inserted into the first insertion hole 21, and a portion of the cylindrical portion is threadedly connected to the first screw hole 31 defined in the base 3a. Therefore, by engaging the male thread of the first screw 201 with the female thread of the first screw hole 31, the cover 2a is fixed to the base 3a. In other words, the cover 2a is threadedly connected to the base 3a using the first screw 201.

[0067] The cover 2a and the base 3a are connected to each other, and the circuit board 1 is supported by the base 3a. In addition, the cover 2a is fixed to the base 3a such that the columnar portion of the first screw 20a is inserted into the first insertion hole 21 and the columnar portion of the first screw 20a engages with the first screw hole 31.

[0068] <Damper>

[0069] Next, refer to Figure 2 and 3A In 3D, damper 6a will be described. Damper 6a is a component used to reduce stress (external force) on circuit board 1. For example, damper 6a absorbs shocks applied to circuit board 1. In addition, damper 6a protects circuit board 1 from stresses such as assembly strain, thermal shock, and vibration. Damper 6a is also referred to as a component that relaxes stress on insulating substrate 4a.

[0070] The damper 6a includes a damper tubular body 61a. A gap G1 exists within the damper tubular body 61a. The damper tubular body 61a corresponds to a tubular body. The damper tubular body 61a is constructed in two forms. Figures 3A to 3D Two forms of the damper tubular body 61a are shown. Figure 3A This is a side view of the tubular body 61a of the damper in the first form. Figure 3B It is along Figure 3A The cross-sectional view taken from line IIIB-IIIB in the diagram. Figure 3C This is a side view of the second type of damper tubular body 61a. Figure 3D It is along Figure 3C The image shows a cross-sectional view of the lines in IIID-IIID. Both forms will be described in detail later.

[0071] The damper tubular body 61a includes a first surface S1, a second surface S2 opposite to the first surface S1, an outer peripheral surface S3 connected to both the first surface S1 and the second surface S2, and an inner peripheral surface S4. The distance between the first surface S1 and the second surface S2 is the height of the damper tubular body 61a. Furthermore, the distance between the outer peripheral surface S3 and the inner peripheral surface S4 is the thickness of the damper tubular body 61a.

[0072] In this embodiment, as an example of the damper tubular body 61a, the first surface S1 and the second surface S2 are parallel to each other. Furthermore, in this embodiment, as an example, the damper tubular body 61a has a cylindrical shape. However, this disclosure is not limited thereto. The first surface S1 corresponds to the first end. The second surface S2 corresponds to the second end.

[0073] The damper tubular body 61a defines a through hole H1 extending between a first surface S1 and a second surface S2. The through hole H1 is surrounded by an inner peripheral surface S4. In other words, the damper tubular body 61a defines a through hole H1 along a second insertion hole 41a when the damper 6a is held by the circuit board 1 (insulating substrate 4a).

[0074] The gap G1 extends between a first surface S1 and a second surface S2 of the damper tubular body 61a. Therefore, when viewed from either the first surface S1 or the second surface S2, the damper tubular body 61a has an annular shape, a portion of which is cut off at the gap G1. The damper tubular body 61a includes a first end surface S5 as one end in the circumferential direction and a second end surface S6 as the other end in the circumferential direction. The gap G1 is the region between the first end surface S5 and the second end surface S6. Therefore, the first end surface S5 and the second end surface S6 are positioned facing each other across the gap G1. The gap G1 can be described as a slit, slot, etc.

[0075] Here, two forms of the damper tubular body 61a will be described. The damper tubular body 61a can be in a first form having an external shape smaller than that of the second insertion hole 41a, and in a second form having an external shape equal to or larger than that of the second insertion hole 41a. In other words, the external shape of the damper tubular body 61a in the first form is smaller than the opening area of ​​the second insertion hole 41a. On the other hand, the external shape of the damper tubular body 61a in the second form is larger than the opening area of ​​the second insertion hole 41a. Therefore, the damper tubular body 61a in the first form can be inserted into the second insertion hole 41a without deformation. On the other hand, the damper tubular body 61a in the second form cannot be inserted into the second insertion hole 41a without deformation. The external shape of the damper tubular body 61a is the region surrounded by the annular curve defined by the outer peripheral surface S3.

[0076] Specifically, in this embodiment, as an example, the damper tubular body 61a can deform between a first form with a small gap G1 and a second form with a wide gap G1. That is, the gap G1 in the second form is wider than the gap G1 in the first form. In other words, the gap G1 in the first form is narrower than the gap G1 in the second form. Figure 3BAs shown, in the first form, the gap G1 has a first distance R11 between the first end surface S5 and the second end surface S6. On the other hand, as... Figure 3D As shown, in the second form, the gap G1 has a second distance R12 between the first end surface S5 and the second end surface S6. The first distance R11 is shorter than the second distance R12. As described above, the gap G1 has different dimensions between the first and second forms.

[0077] The first end surface S5 and the second end surface S6 of the first-type damper tubular body 61a are closer to each other than those of the second type and are connected using adhesive 7. That is, the first-type damper tubular body 61a is closer to each other along the first end surface S5 than the second-type damper tubular body 61a. Figure 3B The white arrow in the diagram is pressed down while the adhesive 7 is used for connection. When the adhesive 7 is heated and melted, the damper tubular body 61a deforms from the first form to the second form using restoring force. Therefore, as... Figure 3B and 3D As shown, the damper tubular body 61a has an elliptical shape in the first form and a shape that is closer to a perfect circle than an elliptical shape in the second form.

[0078] also, Figure 3B The reference numeral R1 in the figure is assigned to the first outer diameter of the damper tubular body 61a in the first form. The first outer diameter R1 is shorter than the inner diameter R21 of the second insertion hole 41a.

[0079] Figure 3D The reference numeral R2a in the accompanying drawings is assigned to the second outer diameter of the damper tubular body 61a in the second form. More specifically, the outer diameter in the second form differs between the state in which the damper tubular body 61a is inserted into the second insertion hole 41a and the state in which the damper tubular body 61a is not inserted into the second insertion hole 41a. The second outer diameter R2a is the outer diameter in the second form when the damper tubular body 61a is not inserted into the second insertion hole 41a. The second outer diameter R2a is equal to the diameter of the damper tubular body 61a when no external force is applied to it.

[0080] On the other hand, such as Figure 6 As shown, the third outer diameter R2b is defined as the outer diameter of the damper tubular body 61a in its second form when inserted into the second insertion hole 41a. The third outer diameter R2b is equal to the inner diameter R21 of the second insertion hole 41a. The second outer diameter R2a is longer than the third outer diameter R2b.

[0081] As will be described in detail later, the damper tubular body 61a is inserted into the second insertion hole 41a and the insertion hole surface S11 is pressed down, thereby holding the damper tubular body 61a in the insulating substrate 4a. To achieve this, the damper tubular body 61a is formed such that the second outer diameter R2a is longer than the third outer diameter R2b. Similarly, the second distance R12 differs between the state where the damper tubular body 61a is inserted into the second insertion hole 41a and the state where the damper tubular body 61a is not inserted into the second insertion hole 41a.

[0082] Each of the outer diameters R1, R2a, and R2b is a distance on a virtual straight line along the central axis extending from the through-hole H1 of the damper tubular body 61a on the outer peripheral surface S3 of the damper tubular body 61a. Furthermore, each of the outer diameters R1, R2a, and R2b is a distance on the portion of the damper tubular body 61a facing the insertion hole surface S11 when it is inserted into the second insertion hole 41a.

[0083] In the first form of the damper tubular body 61a, the first end surface S5 and the second end surface S6 are connected by an adhesive 7. That is, the gap G1 is filled with adhesive 7. As the adhesive 7, an adhesive that melts upon heating is used.

[0084] The damper 6a may have a configuration in which a portion of the damper tubular body 61a along the through direction is deformable between a first form and a second form. That is, when the damper 6a is connected to the circuit board 1, only the portion of the damper 6a to be disposed in the second insertion hole 41a and the portion of the damper 6a to pass through the second insertion hole 41a may deform between the first form and the second form.

[0085] The damper tubular body 61a is constructed to be elastically deformable. Therefore, in this embodiment, a wire mesh is used as an example of the damper tubular body 61a. The wire mesh is formed by weaving metal wires to define a space within the damper tubular body 61a. The wire mesh is not limited to a regular weave of metal wires. The wire mesh can be formed by complexly weaving metal wires so that the wires become entangled with each other. The damper tubular body 61a is also referred to as an impact absorbing member or a stress buffer member.

[0086] Furthermore, wire mesh is also referred to as a continuous porous body in which metal wires are entangled with each other. In other words, wire mesh is formed by compressing the entangled metal wires. Wire mesh is also called a metal cushioning component. For example, stainless steel can be used as the metal wire. However, the metal wire is not limited to stainless steel. Aluminum, iron, etc., can also be used as the metal wire. When using wire mesh, the binder 7 can be an organic material, such as resin or solder used for metal bonding, as long as the binder 7 melts when heated.

[0087] However, this disclosure is not limited thereto. The damper tubular body 61a may be primarily made of shape memory alloy. This is preferred because the damper tubular body 61a can easily be deformed from a first form to a second form. Furthermore, the damper tubular body 61a may be made of rubber or the like. However, when rubber is used, the adhesive 7 is preferably an organic material such as resin.

[0088] Furthermore, the damper tubular body 61a may include a protective member primarily composed of a viscoelastic organic material. For example, a silicone member may be used as the protective member. The protective member primarily protects the damper tubular body 61a from functional degradation. That is, the protective member restricts foreign matter from adhering to the damper tubular body 61a to prevent functional degradation. In addition, the protective member also restricts scrap metal and other materials from falling from the damper tubular body 61a to its periphery. The protective member is immersed in the damper tubular body 61a, thereby protecting the space within the mesh of the damper tubular body 61a. Foreign matter adhering to or entering the damper tubular body 61a may be substances containing water, salt, oil, etc.

[0089] The viscosity of the protective component is changed by UV curing or the like. Furthermore, while the protective component is placed in the space, its viscosity is adjusted by ultraviolet light or the like. At this time, adjusting the viscosity allows the characteristics of the damper 6a to reach a desired value. In other words, the compressibility of the damper tubular body 61a is adjusted to a desired value by regulating the viscosity of the protective component.

[0090] The damper 6a is held in the second insertion hole 41a of the insulating substrate 4a. The damper 6a is held in a state where the damper tubular body 61a is press-fitted into the second insertion hole 41a. Therefore, the damper 6a is held in the second insertion hole 41a by the restoring force of the damper tubular body 61a. The damper 6a is held in a state where at least two points on the outer peripheral surface S3 are in contact with the insertion hole surface S11 of the second insertion hole 41a by pressure. Furthermore, the damper tubular body 61a in a second form is disposed in the second insertion hole 41a and presses against the insertion hole surface S11 of the second insertion hole 41a. In other words, the damper 6a is fixed to the second insertion hole 41a by the restoring force of the damper tubular body 61a.

[0091] like Figure 2As shown, the damper 6a is held in the second insertion hole 41a while being pressed against the base 3a by the second screw 202. In other words, when the second screw 202 is screwed into the second screw hole 32, the damper 6a is held between the screw head 202b and the base 34a. In this state, the first surface S1 of the damper 6a contacts the base pressing surface S21 and the second surface S2 of the damper 6a contacts the screw pressing surface S31. In this way, the circuit board 1 is supported by the base 3a via the damper 6a. In this embodiment, as an example, the damper 6a defines a gap G1. However, this disclosure is not limited to this, and as shown in the eighth modification, the gap G1 may not be defined in the damper 6a.

[0092] <Manufacturing Method>

[0093] Reference Figure 4 , 5 Sections 6 and 7 will describe methods for manufacturing the electronic controller 100. For example... Figure 4 As shown, the method includes (a) a preparation step, (b) an insertion step, (c) a deformation step, (d) an installation step, and (e) a covering step. Furthermore, the insertion and deformation steps correspond to the method of connecting the damper 6a to the circuit board 1.

[0094] exist Figure 4 In step (a), a first structure is prepared in which circuit element 51 is disposed on insulating substrate 4a. Figure 4 In step (b), the damper tubular body 61a, in its first form, is inserted into the second insertion hole 41a. At this time, the damper tubular body 61a has a first outer diameter R1. Therefore, as... Figure 5 As shown, there is a sufficient gap between the outer peripheral surface S3 of the damper 6a and the insertion hole surface S11. Therefore, during the insertion step, the damper 6a can be easily inserted into the second insertion hole 41a. Furthermore, during the insertion step, a support member or the like is preferably used to prevent the damper 6a from falling out of the second insertion hole 41a. After the insertion step, the circuit element 51 can be disposed on the insulating substrate 4a.

[0095] exist Figure 4 In the deformation step (c) shown, after the insertion step, the adhesive 7 is heated and melted, and the damper 6a deforms into a second form. As a result, the damper tubular body 61a presses against the insertion hole surface S11. At this time, the damper tubular body 61a has a third outer diameter R2b. Therefore, as Figure 6 As shown, the damper 6a presses against the insertion hole surface S11 along its entire circumference, except for the gap G1. Therefore, there is no gap between the outer circumferential surface S3 of the damper 6a and the insertion hole surface S11. In this way, during the deformation step, the tubular body 61a of the damper deforms, so that the damper 6a is held in the insulating substrate 4a.

[0096] However, this disclosure is not limited thereto. In this invention, only at least two points on the outer peripheral surface S3 are required to press against the insertion hole surface S11.

[0097] The manufacturing method includes a reflow step of mounting circuit elements 51 and 52 onto an insulating substrate 4a. In the reflow step, the terminals of circuit elements 51 and 52 and the wiring pattern 42 are connected using solder 51a via reflow soldering. In the reflow step, the first structure is heated in a reflow oven to melt the solder 51a. Therefore, the deformation step can be performed concurrently with the reflow step. As described above, in the assembly method of this embodiment, it is not necessary to perform the deformation step separately from the reflow step.

[0098] The second structure is one in which circuit elements 51 and 52 are mounted on an insulating substrate 4a and the damper 6a is held within the insulating substrate 4a. That is, the second structure is one in which the damper 6a is attached to the circuit board 1.

[0099] In this embodiment, the adhesive 7 is heated and melted to deform the damper tubular body 61a. Therefore, the damper tubular body 61a is preferably formed by braiding metal wires. However, the damper tubular body 61a can be made of rubber or the like, which can withstand the temperature at which the adhesive 7 melts.

[0100] exist Figure 4 In the installation step (d) shown, the second structure is disposed on the base 3a. In this installation step, the second structure is disposed at the position where the through hole H1 faces the second screw hole 32. Furthermore, in this installation step, the second structure is disposed at the position where the first surface S1 of the damper 6a contacts the pressing surface S21 of the base.

[0101] Next, during the installation step, the second screw 202 is screwed into the second screw hole 32. At this time, the damper 6a is pressed by the screw pressing surface S31. Simultaneously, the base pressing surface S21 is pressed by the damper 6a. Therefore, while the damper 6a is in contact with both the base pressing surface S21 and the screw pressing surface S31, the damper 6a is pressed (compressed) between the screw head 202b and the base 34a. In this way, the circuit board 1 is supported by the base 3a via the damper 6a.

[0102] After the installation step, the damper tubular body 61a may have a configuration in which a gap is defined between the inner circumferential surface S4 and the columnar portion 202a, or it may have a configuration in which no gap is defined. However, the damper tubular body 61a preferably has a configuration in which a gap is defined, because the damper tubular body 61a can more easily elastically deform in the planar direction compared to a configuration without a defined gap.

[0103] exist Figure 4In the covering step shown (e), after the installation step, the cover 2a is attached to the base 3a to accommodate the second structure. In the covering step, the cover 2a is positioned on the base 3a on which the second structure is mounted. At this time, the cover 2a is positioned with the first insertion hole 21 facing the first screw hole 31. In the covering step, the first screw 201 is screwed into the first screw hole 31. Thus, an electronic controller 100 with the second structure accommodated in the receiving space defined by the base 3a and the cover 2a can be manufactured.

[0104] <Effect>

[0105] In this manner, the circuit board 1 is supported by the base 3a via a damper 6a fixed to the insulating substrate 4a. Furthermore, the damper 6a is pressed between the screw head 202b and the base 34a. Therefore, the stress applied to the insulating substrate 4a in the thickness direction causes the damper 6a to elastically deform in the thickness direction between the screw head 202b and the base 34a. The damper 6a has a region facing the insertion hole surface S11. The upper and lower portions of this region of the damper 6a undergo primarily elastic deformation. Therefore, when stress is applied to the insulating substrate 4a in the thickness direction, the damper 6a can protect the circuit board 1.

[0106] Furthermore, the damper 6a defines a gap G1. Therefore, the damper 6a readily undergoes elastic deformation in the intersecting direction. Thus, the damper 6a can relax not only the stress on the circuit board 1 along the thickness direction, but also the stress on the circuit board 1 along the intersecting direction. Therefore, the damper 6a can appropriately relax the stress on the circuit board 1. While the damper 6a is pressed down by the second screw 202, a gap can exist between the inner circumferential surface S4 and the columnar portion 202a. Through this gap, the damper 6a readily undergoes elastic deformation in the intersecting direction.

[0107] Furthermore, the damper 6a is configured to form both a first and a second form. Therefore, the damper 6a can be easily inserted into the second insertion hole 41a and easily fixed to the insulating substrate 4a. That is, since the damper 6a can be formed in the first form, in which the external shape of the damper tubular body 61a is smaller than that of the second insertion hole 41a, the damper 6a can be easily inserted into the second insertion hole 41a. Furthermore, since the damper tubular body 61a is configured in the second form, in which the external shape of the damper tubular body 61a is equal to or larger than that of the second insertion hole 41a, the damper 6a can ensure a holding force on the circuit board 1. As described above, the damper 6a can be easily inserted into the second insertion hole 41a, while the damper 6a ensures a holding force on the circuit board 1.

[0108] The electronic controller 100 includes a damper 6a. The damper 6a has the effects described above. Therefore, the electronic controller 100 can limit the cracking of solder 51a, wiring pattern 42, etc., due to stress applied to the insulating substrate 4a, or limit the failure of circuit elements 51 and 52 due to such stress. Therefore, the electronic controller 100 can suppress adverse effects on the electrical characteristics of the circuit board 1.

[0109] More specifically, circuit board 1 is supported by base 3a using second screw 202. However, circuit board 1 is also supported by base 3a via damper 6a. Therefore, when circuit board 1 itself deforms or an external force is applied to circuit board 1, damper 6a elastically deforms. Thus, in circuit board 1, cracking of solder 51a, wiring pattern 42, etc., caused by stress applied to insulating substrate 4a can be limited, and failure of circuit elements 51 and 52 due to this stress can be limited.

[0110] Furthermore, in the electronic controller 100, the effects of assembly deformation can be reduced by adjusting the mounting positions of circuit elements 51 and 52. That is, in the electronic controller 100, circuit elements 51 and 52 can be mounted away from the screw connection location to avoid the effects of assembly deformation. In this case, the distance between the screw connection location and circuit elements 51 and 52 in the electronic controller 100 could be a factor hindering high-density mounting. However, in this embodiment, the damper 6a mitigates the effects of assembly deformation. Therefore, in the electronic controller 100, circuit elements 51 and 52 can be mounted at a high density.

[0111] In this embodiment, a wire mesh is used as an example of the damper tubular body 61a. Therefore, compared to the case where rubber is used as the damper tubular body 61a, the deterioration of the damper 6a over time can be limited.

[0112] In this embodiment, the second screw 202 is used as an example of a support element. However, in this disclosure, a component utilizing elastic deformation, such as a snap-fit, can be used as a support element. Furthermore, in this embodiment, the circuit board 1 is used as an example of a supported component. However, in this disclosure, the base 3a can be a supported component. In this case, the support component can be a vehicle frame, etc. Furthermore, in this disclosure, the cover 2a can be a supported component. In this case, the base 3a can be a support component. The first screw 201 can be used as a support element.

[0113] The circuit board 1 can be supported by the base 3a using a first screw 201 instead of a second screw 202. In this case, the first screw 201 corresponds to a support element.

[0114] (First Amendment Example)

[0115] Reference Figure 7The electronic controller 100 of the first modified example will be described below. In the electronic controller 100 of the first modified example, the construction of the insulating substrate 4b differs from that of the above embodiment. However, for convenience, the electronic controller 100 of the first modified example is labeled with the same reference numerals as in the above embodiment. In other modifications and embodiments, the electronic controller 100 is referred to as reference numeral 100.

[0116] like Figure 7 As shown, the shape of the second insertion hole 41b of the insulating substrate 4b differs from that of the insulating substrate 4a. The second insertion hole 41b is a through hole surrounded by an insertion hole surface S11. The insertion hole surface S11 has an annular shape, a portion of which is cut off. In other words, the second insertion hole 41b is a recessed portion from the sidewall of the insulating substrate 4b. The damper 6a can be inserted into the second insertion hole 41b along the thickness direction. Furthermore, the damper 6a can be inserted into the second insertion hole 41b in a direction perpendicular to the thickness direction. The electronic controller 100 of the first modified example can achieve similar effects to the above embodiment. The first modified example can be applied to other embodiments and other modifications.

[0117] (Second Amendment)

[0118] Reference Figure 8 The electronic controller 100 of the second modification will now be described. The electronic controller 100 of the second modification differs from the one described above in the construction of the insulating substrate 4c.

[0119] like Figure 8 As shown, the shape of the second insertion hole 41c of the insulating substrate 4c differs from that of the insulating substrate 4a. The second insertion hole 41c is surrounded by an annular insertion hole surface S11, and the opening diameter of the second insertion hole 41c differs in the thickness direction. The second insertion hole 41c is divided into a portion into which the damper 6a and the columnar portion 202a of the second screw 202 are inserted, and a portion into which the damper 6a is not inserted. A portion of the columnar portion 202a of the second screw 202 is inserted into the portion into which the damper 6a is not inserted. The portion into which the damper 6a and the columnar portion 202a of the second screw 202 are inserted has a substrate pressing surface S41 as a bottom surface.

[0120] Therefore, the damper 6a is inserted into the second insertion hole 41c, and the second surface S2 of the damper 6a contacts the base pressing surface S41. Furthermore, the damper 6a is pressed between the base pressing surface S41 and the base pressing surface S21. The electronic controller 100 of the second modification can achieve similar effects to the above embodiment. The second modification can be suitably applied to other embodiments and other modifications.

[0121] (Second Embodiment)

[0122] Reference Figure 9A , 9B Sections 10 and 10 will describe the damper 6b of the second embodiment. In this embodiment, the parts that differ from the first embodiment will be described primarily. The difference between this embodiment and the first embodiment lies in the construction of the damper 6b, the cover 2b, and the base 3b. In this embodiment, the same reference numerals are used for the same construction as in the first embodiment.

[0123] like Figure 9A and 9B As shown, the difference between damper 6b and damper 6a is that damper 6b includes a damper protrusion 62b. Damper 6b includes a damper tubular body 61b and a damper protrusion 62b. The damper tubular body 61b is the same as that of damper tubular body 61a.

[0124] The damper protrusion 62b corresponds to the protrusion. The damper protrusion 62b protrudes from the outer peripheral surface S3 of the damper tubular body 61b. The damper protrusion 62b is provided to prevent the damper 6b in the first form from falling out of the second insertion hole 41a.

[0125] The damper protrusion 62b is disposed within a predetermined range from the second surface S2 in the height direction of the damper tubular body 61b. That is, the damper protrusion 62b is not disposed in the entire region of the damper tubular body 61b in the height direction, but only in a portion of the damper tubular body 61b in the height direction.

[0126] Furthermore, the damper protrusion 62b is only provided on a portion of the outer peripheral surface S3 in the circumferential direction. However, this disclosure is not limited to this, and it is only necessary to provide the damper protrusion 62b on at least a portion of the damper tubular body 61b in the circumferential direction. Therefore, the damper protrusion 62b can be a plurality of damper protrusions arranged in the circumferential direction. For example, two, three, four or more damper protrusions 62b can be arranged at equal intervals in the circumferential direction. In addition, the damper protrusion 62b can be provided in the entire region in the circumferential direction.

[0127] The damper protrusion 62b may be made of the same material as the damper tubular body 61b, or it may be made of a different material. Furthermore, the damper protrusion 62b may be integrally formed with the damper tubular body 61b, or it may be formed by connecting different components.

[0128] Here, refer to Figure 10 The method for manufacturing an electronic controller 100 including a damper 6b will be described. Furthermore, the construction of the electronic controller 100 will also be described herein. Figure 10 The preparation and deformation steps shown are the same as those in the first embodiment.

[0129] In the insertion step (b) shown in 10, as in the first embodiment, the damper tubular body 61b in the first form is inserted into the second insertion hole 41a. At this time, there is a sufficient gap between the outer peripheral surface S3 of the damper 6b and the insertion hole surface S11. Therefore, in the insertion step, the damper 6b can be easily inserted into the second insertion hole 41a.

[0130] However, the damper 6b includes a damper protrusion 62b. Therefore, the damper protrusion 62b of the damper 6b is positioned near the second insertion hole 41a of the insulating substrate 4a. Thus, during the insertion step, the damper 6b can be prevented from disengaging from the second insertion hole 41a.

[0131] exist Figure 10 In the installation step (d) shown, the second structure is disposed on the base 3b, as in the first embodiment. The base 3b will be described here. The base 3b differs from the base 3a in that it includes a base positioning part 35b and a distance adjustment part 36b. The pedestal 34b is the same as the pedestal 34a.

[0132] The base positioning part 35b positions the damper 6b relative to the base 3b. The base positioning part 35b protrudes from the platform 34b in the thickness direction. The base positioning part 35b is inserted into the through hole H1 of the damper 6b.

[0133] The distance adjustment section 36b restricts the inner circumferential surface S4 of the damper tubular body 61b to become too close to the required distance. The distance adjustment section 36b protrudes from the front end of the base positioning section 35b in the thickness direction. The thickness direction is the same as the direction perpendicular to the base pressing surface S21. The base 3b may not include the distance adjustment section 36b.

[0134] In the installation step, the second structure is placed on the base 3b, such that the base positioning part 35b and the distance adjustment part 36b are inserted into the through hole H1. Furthermore, in the installation step, the second structure is positioned at the location where the first surface S1 contacts the base pressing surface S21. Therefore, in the installation step, the damper 6b can be positioned appropriately on the base 3b. Therefore, in the installation step, the second structure can be positioned appropriately.

[0135] In the installation steps of this embodiment, the second screw 202 is not used. Therefore, during the installation phase, the second structure is only installed on the base 3b.

[0136] exist Figure 10 In the covering step shown in (e), the cover 2b is attached to the base 3b to accommodate the second structure as in the first embodiment. Here, the cover 2b will be described. The cover 2b differs from the cover 2a in that the cover 2b includes a cover protrusion 22b and a cover positioning portion 23b.

[0137] A cover protrusion 22b is provided on the side of the cover 2b facing the receiving space. The cover protrusion 22b is the part that presses the damper 6b against the base 34b. The cover protrusion 22b protrudes further in the thickness direction than its periphery. The front end of the cover protrusion 22b has a cover pressing surface S51 for pressing the damper 6b.

[0138] The cover positioning portion 23b positions the damper 6b relative to the cover 2b. The cover positioning portion 23b protrudes from the front end of the cover protrusion 22b in the thickness direction. That is, the cover pressing surface S51 is the portion of the front end of the cover protrusion 22b where the cover positioning portion 23b is not provided.

[0139] In the covering step, the cover 2b is placed on the base 3b on which the second structure is mounted. At this time, the cover positioning part 23b is inserted into the through hole H1 to set the cover 2b. In the covering step, the first screw 201 is screwed into the first screw hole 31.

[0140] When the first screw 201 engages with the first screw hole 31, the cover pressing surface S51 presses against the damper 6b. Simultaneously, the base pressing surface S21 is pressed against the damper 6b. Therefore, while the damper 6b is in contact with both the base pressing surface S21 and the cover pressing surface S51, the damper 6a is pressed between the cover protrusion 22b and the pedestal 34b. In this way, the circuit board 1 is supported by the base 3b via the damper 6b. Thus, an electronic controller 100 in which a second structure is housed within the receiving space defined by the base 3a and the cover 2a can be manufactured.

[0141] Damper 6b can perform a similar effect to damper 6a. Damper 6b has a region facing the insertion hole surface S11. The upper and lower portions of this region of damper 6b elastically deform due to the stress applied to the insulating substrate 4a in the thickness direction. Furthermore, in damper 6b, damper protrusion 62b elastically deforms between the insulating substrate 4a and the cover protrusion 22b. Therefore, when stress is applied to the insulating substrate 4a in the thickness direction, damper 6b can protect circuit board 1.

[0142] Furthermore, the damper 6b includes a damper protrusion 62b. Therefore, the damper 6b in its first form can be held in the second insertion hole 41a. That is, the damper 6b can be held in the second insertion hole 41a without using a clamp such as a support base.

[0143] In the method of this embodiment, since the damper 6b includes a damper protrusion 62b, the damper 6b can be prevented from falling out of the second insertion hole 41a during the insertion step. Therefore, the method of this embodiment does not require the use of a support base or the like.

[0144] The damper 6b can be applied to the first embodiment and its modifications. The cover 2b and base 3b can be applied to the first embodiment and its modifications. Furthermore, the electronic controller 100 of this embodiment can employ a cover 2a and a base 3a. In this case, a second screw 202 is used.

[0145] (Third Amendment Example)

[0146] Reference Figures 11A to 11D The third modified example of the damper 6c will be described. In this modification, the differences from the second embodiment will be mainly described. The main difference between the damper 6c of the third modified example and the second embodiment is that the damper 6c includes a damper protrusion 62c and a tab 63c. Figures 11A to 11D Two forms of the damper tubular body 61c and the insulating substrate 4a are shown. Figure 11A It is a first-form plan view. Figure 11B It is along Figure 11A A cross-sectional view taken from line XIB-XIB in the diagram. Figure 11C It is a second form of plan view. Figure 11D It is along Figure 11C The cross-sectional view taken by line XID-XID in the diagram.

[0147] like Figures 11A to 11D As shown, the damper 6c includes a tubular body 61c, damper protrusions 62c, tabs 63c, and recesses 64c. The tubular body 61c is identical to the tubular body 61b. Each of the damper protrusions 62c is identical to the damper protrusion 62b, except for the number of protrusions. Each of the damper protrusions 62c corresponds to a second protrusion.

[0148] Each of the tabs 63c corresponds to a first protrusion. The tabs 63c protrude from the outer peripheral surface S3 of the damper tubular body 61c. The tabs 63c are configured to hold the insulating substrate 4a together with the damper protrusions 62c.

[0149] The tab 63c is disposed within a predetermined range from the first surface S1 in the height direction of the damper tubular body 61b. That is, the tab 63c is not disposed in the entire region of the damper tubular body 61b in the height direction, but only in a portion of the damper tubular body 61b in the height direction.

[0150] Furthermore, tabs 63c are only provided on a portion of the outer peripheral surface S3 in the circumferential direction. However, this disclosure is not limited to this. Tabs 63c need only be provided on at least a portion of the damper tubular body 61b in the circumferential direction. Therefore, tabs 62b can be a plurality of tabs arranged in the circumferential direction. For example, two, three, four or more tabs 62b can be arranged at equal intervals in the circumferential direction. Furthermore, tabs 62b can be provided in the entire region in the circumferential direction.

[0151] The tab 63c tapers gradually from the side of the tab 63c closest to the second surface S2 toward the first surface S1. This makes it easier for the damper 6c to be inserted into the second insertion hole 41a.

[0152] The tab 63c can be made of the same material as the damper tubular body 61b, or it can be made of a different material. Furthermore, the tab 63c can be integrally formed with the damper tubular body 61b, or it can be formed by connecting different components.

[0153] Each of the recesses 64c is disposed between the damper protrusion 62c and the tab 63c. The recess 64c is located further inward of the damper protrusion 62c and the tab 63c. The opening width of the recess 64c is equal to or greater than the thickness of the insulating substrate 4a. The opening width is the width of the recess 64c in the height direction of the damper tubular body 61c. Furthermore, the opening width corresponds to the distance in the height direction between the damper protrusion 62c and the tab 63c. The bottom surface of the recess 64c is the outer peripheral surface S3.

[0154] like Figure 11A and 11B As shown, in the first form, the damper protrusion 62c extends between the facing region and the outer side of the second insertion hole 41a. The facing region is defined by virtually extending the region of the second insertion hole 41a in the thickness direction. Figure 11C and 11D As shown, in the second form, the damper protrusion 62c is located on the outer side of the facing area of ​​the second insertion hole 41a.

[0155] On the other hand, such as Figure 11B As shown, in the first form, the tab 63c is disposed in the facing area of ​​the second insertion hole 41a. (As...) Figure 11D As shown, in the second form, the tab 63c is disposed on the outer side of the facing area of ​​the second insertion hole 41a.

[0156] As described above, when the damper 6c is in its second form, the end of the insulating substrate 4a can be disposed in the recess 64c. Therefore, when stress is applied to the insulating substrate 4a along the thickness direction, the upper and lower parts of the damper 6b facing the insertion hole surface S11 undergo elastic deformation. Furthermore, the damper protrusion 62c and the tab 63c of the damper 6c undergo elastic deformation. Therefore, when stress is applied to the insulating substrate 4a along the thickness direction, the damper 6a can protect the circuit board 1.

[0157] Damper 6c can perform similar effects to dampers 6a and 6b. Furthermore, damper 6c includes a damper protrusion 62c, a tab 63c, and a recess 64c. Therefore, damper 6c can properly position the insulating substrate 4a relative to damper 6a. Additionally, damper 6c can hold the insulating substrate 4a between the damper protrusion 62c and the tab 63c. Therefore, compared to damper 6a, damper 6c can improve the holding force on the insulating substrate 4a.

[0158] In the electronic controller 100 including the damper 6c, the insulating substrate 4a is held by the damper protrusion 62c and the tab 63c. Therefore, in the electronic controller 100, the insulating substrate 4a can be held more forcefully than when the insulating substrate 4a is held by the damper 6a. Therefore, in the electronic controller 100, compared with the case including the damper 6a, the circuit board 1 can be protected more reliably when stress is applied to the insulating substrate 4a along the thickness direction.

[0159] (Fourth Amendment Example)

[0160] Reference Figure 12 The fourth modified example of the damper 6b will be described. In this modified example, the parts that differ from the second embodiment will be mainly described. The damper 6b differs from the damper in the second embodiment in that it includes a height adjustment member 6b1. However, in this modified example, for convenience, the same reference numerals as in the second embodiment will be used. Figure 12 The base 3b in the second embodiment has a structure in which the distance adjustment part 36b is not provided. Figure 12 The base 3b in the second embodiment has the same structure as the base 3b described in the second embodiment, except for the distance adjustment part 36b.

[0161] The damper 6b includes a height adjusting member 6b1 at a location surrounded by the damper tubular body 61b. The height adjusting member 6b1 corresponds to an adjusting member. The height adjusting member 6b1 has, for example, a tubular shape.

[0162] The height adjustment component 6b1 is primarily made of metal. However, this disclosure is not limited thereto. Components primarily made of resin can also be used as the height adjustment component 6b1.

[0163] The height adjustment member 6b1 is configured to adjust the height of the damper tubular body 61b, which is the distance between the first surface S1 and the second surface S2. Furthermore, the height adjustment member 6b1 can be said to be configured to set the compressibility of the damper tubular body 61b to a desired value. That is, since the damper 6b includes the height adjustment member 6b1, it can limit the damper 6b from being compressed beyond a required degree by the second screw 202, etc., and prevent it from losing its function of relaxing the stress to the circuit board 1. The damper 6b of the fourth modification can also achieve a similar effect to the damper 6b of the second embodiment. The height adjustment member 6b1 can also be applied to the first embodiment and other modifications.

[0164] (Fifth Amendment)

[0165] Reference Figure 13 The fifth modified example of the damper 6d will be described. In this modified example, the differences from the second embodiment will be mainly described. The difference between the damper 6d and the second embodiment is that it includes a cover.

[0166] The damper 6d includes a tubular body 61d and a protrusion 62d. The tubular body 61d is the same as the tubular body 61b. The protrusion 62d is the same as the protrusion 62b.

[0167] The cover includes a bottom surface cover 6d3 and components with side surfaces 6d1 and a top surface 6d2. The side surfaces 6d1, top surface 6d2, and bottom cover 6d3 are mainly made of metal, resin, etc. The side surfaces 6d1, top surface 6d2, and bottom cover 6d3 can be made of the same material or different materials.

[0168] For example, side surface 6d1 and top surface 6d2 are integrally formed together. Side surface 6d1 is a tubular member and is configured to face the inner circumferential surface S4. Side surface 6d1 also serves as a height adjustment member. Top surface 6d2 is disposed at the end of side surface 6d1. Top surface 6d2 is configured to face the second surface S2.

[0169] The bottom cover 6d3 is positioned to face the first surface S1. The bottom cover 6d3 is a component distinct from the side surface 6d1. The bottom cover 6d3 is positioned to face the side surface 6d1. The damper tubular body 61d is disposed between the upper surface 6d2 and the bottom cover 6d3.

[0170] The damper 6d can achieve similar effects to the second embodiment and the fourth modification. Furthermore, the side surface 6d1, upper surface 6d2, and bottom cover 6d3 of the damper 6d can protect the tubular body 61d and the damper protrusion 62d. That is, it can limit the adhesion of foreign matter to the tubular body 61d and the protrusion 62d of the damper 6d. Therefore, the deterioration of the damper 6d caused by foreign matter adhering to it can be limited.

[0171] (Third Embodiment)

[0172] Reference Figure 14 and 15 The electronic controller 100 of the third embodiment will be described. In this embodiment, the differences from the second embodiment will be mainly described. In this embodiment, the construction of the second screw 203 differs from that of the second embodiment. Meanwhile, in this embodiment, the shape of the damper 6b differs from that of the second embodiment. Furthermore, in this embodiment, the construction and deformation steps of the base 3c differ from those of the second embodiment.

[0173] like Figure 14 and 15 As shown, the base 3c includes a platform 34c, a base positioning portion 35c, and a second screw hole 32. The platform 34c is identical to the platform 34b. The base positioning portion 35c is identical to the base positioning portion 35b. The second screw hole 32 is defined in the base positioning portion 35c. That is, the base 3c can be considered to have a structure in which the distance adjustment portion 36b is omitted from the base 3b and the second screw hole 32 is defined in the base 3b. However, the base 3c may include the distance adjustment portion 36b that defines the second screw hole 32.

[0174] like Figure 15 As shown, the second screw 203, similar to the second screw 202, includes a columnar portion 203a and a screw head 203b. The second screw 203 corresponds to the fixing member, the columnar portion corresponds to the fixing portion, and the screw head 203b corresponds to the pressing portion. The columnar portion 203a is identical to the columnar portion 202a. The screw head 203b has a screw inclined surface S32 at the position where it presses the tubular body 61b of the damper. The screw inclined surface S32 has an annular shape. The screw head 203b has a shape in which the cross-sectional area of ​​the screw head 203b increases in the direction away from the columnar portion 203a. That is, a screw head 203b with a tapered shape is provided at the end of the columnar portion 203a.

[0175] As will be described later, the screw head 203b is the part that transforms the damper tubular body 61b from the first form to the second form. That is, the screw head 203b is the part that enlarges the diameter of the damper tubular body 61b. Therefore, the screw head 203b can be referred to as the enlarged part.

[0176] The damper 6b includes an end corner surface S7 along the screw inclined surface S32. The end corner surface S7 is disposed between the first surface S1 and the inner circumferential surface S4. The end corner surface S7 is a surface pressed by the second screw 203 and deformed along the screw inclined surface S32. In this case, the end corner surface S7 can be considered as a surface formed by a portion of the first surface S1 and a portion of the inner circumferential surface S4. The end corner surface S7 can be a surface pre-set in the damper tubular body 61b along the screw inclined surface S32. The end corner surface S7 is also referred to as the inner circumferential corner surface.

[0177] Here, we will refer to Figure 14 A method for manufacturing an electronic controller 100 including a damper 6b is described. The covering steps in this embodiment are omitted since they are the same as in the first embodiment.

[0178] exist Figure 14 In the preparation step (a) shown, circuit element 51 and the like are mounted on the insulating substrate 4a. The mounting method of circuit element 51 is the same as in the first embodiment.

[0179] exist Figure 14 In the setup step shown in (b), the damper 6b in the first form is mounted on the base 3c. In this setup step, the second surface S2 is positioned to face the platform 34c. Furthermore, in this setup step, the base positioning portion 35c is inserted into the through hole H1.

[0180] exist Figure 14 In the insertion step (c) shown, the damper 6b disposed on the base 3c is inserted into the second insertion hole 41a. At this time, as in the first embodiment, there is a sufficient gap between the outer peripheral surface S3 and the insertion hole surface S11. Therefore, in the insertion step, the damper 6b can be easily inserted into the second insertion hole 41a.

[0181] exist Figure 14 In the deformation step (d) shown, the second screw 203 is screwed into the second screw hole 32. During the deformation step, the second screw 203 is screwed into the second screw hole 32 while the inclined screw surface S32 contacts the end corner surface S7. At this time, in the damper 6b, the force from the screw head 203b acts on the damper 6b not only in the thickness direction but also in the planar direction. Therefore, in the damper 6b, the diameter of the tubular body 61b of the damper is enlarged by the force applied from the screw head 203b. Therefore, the first end surface S5 and the second end surface S6 of the damper 6b, which are connected by the adhesive 7, are peeled off. Alternatively, the adhesive 7 can be separated in the damper 6b. Furthermore, since the force from the screw head 203b also acts on the damper 6b in the planar direction, the holding force on the insulating substrate 4a (circuit board 1) is improved.

[0182] As a result, the damper 6b transforms from a first form to a second form. In other words, the diameter of the tubular body 61b of the damper is expanded by the force from the second screw 203. As described above, in the deformation step of this embodiment, the damper 6b changes from the first form to the second form using the force from the second screw 203 rather than heat. Therefore, in the assembly method of this embodiment, the first form can be converted to the second form simply by screwing the second screw 203 in. In this embodiment, the damper 6b can be replaced by either the damper 6a or the damper 6c.

[0183] (Sixth Amendment)

[0184] Reference Figure 16 The following describes a sixth modified example of an electronic controller. In this modification, the differences from the third embodiment will be primarily described. In this modified example, the structure of the base 3d differs from that of the third embodiment. In this modification, a damper 6a is used as an example. However, a damper 6b may also be used in this modification.

[0185] In this modified example, the damper 6a is configured such that the second surface S2 faces the screw head 203b and the first surface S1 faces the base 3c. Therefore, in this modified example, the end corner surface S8 is a surface that extends along the screw inclined surface S32.

[0186] like Figure 16 As shown, the base 3d includes a platform 34d and a base enlargement 35d. The platform 34d is identical to the platform 34c. The base enlargement 35d is the portion of the platform 34d that protrudes from the base pressing surface S21. The base enlargement 35d has a truncated cone shape. The base enlargement 35d has an annular base inclined surface S22. The base pressing surface S21 contacts the first surface S1. On the other hand, the base inclined surface S22 contacts the end corner surface S7 of the damper 6a. The end corner surface S7 will be described later.

[0187] Similar to the screw head 203b, the base enlargement 35d can increase the diameter of the damper tubular body 61d. In addition, the base enlargement 35d also serves as a base positioning part.

[0188] The damper 6a includes an end corner surface S7 near the first surface S1 and an end corner surface S8 near the second surface S2. The end corner surface S7 is a surface that deforms along the inclined surface S22 of the base by means of the pressing force of the second screw 203. In this case, the end corner surface S7 can be considered as a surface formed by a portion of the first surface S1 and a portion of the inner circumferential surface S4. The end corner surface S7 may be a surface pre-configured to extend along the inclined surface S22 of the base. The end corner surface S8 is the same as the end corner surface S7 of the third embodiment. Each of the end corner surfaces S7 and S8 is also referred to as an inner circumferential corner surface.

[0189] In the deformation step of this modified example, the second screw 203 is screwed into the second screw hole 32. During the deformation step, the second screw 203 is screwed into the second screw hole 32 while the screw inclined surface S32 contacts the end corner surface S8 and the base inclined surface S22 contacts the end corner surface S7. At this time, the damper 6a changes from the first form to the second form in the same manner as in the third embodiment.

[0190] Therefore, in the deformation step of this modified example, similar effects to those of the third embodiment can be obtained. Furthermore, the base 3d of this modified example includes a base enlargement 35d. Therefore, compared to the third embodiment, the force used to enlarge the diameter of the damper tubular body 61a is increased. Therefore, in the deformation step of this modified example, compared to the third embodiment, it is easier to transform the damper tubular body 61a from the first form to the second form. Furthermore, the electronic controller of the sixth modified example increases the force used to enlarge the diameter of the damper tubular body 61a, thereby increasing the holding force on the insulating substrate 4a (circuit board 1).

[0191] (Fourth Embodiment)

[0192] Reference Figure 17 The electronic controller 100 of the fourth embodiment will be described. In this embodiment, the differences from the first embodiment will be mainly described. In this embodiment, the construction of the cover 2e and the base 3e differs from that in the first embodiment.

[0193] like Figure 17 As shown, the electronic controller 100 includes a damper 6a, a cover 2e forming a housing, a base 3e, and an insulating substrate 4a. Similar to the first embodiment, the electronic controller 100 includes a circuit board 1 having the insulating substrate 4a. The circuit board 1 corresponds to the supported portion.

[0194] like Figure 17 As shown, the cover 2e includes a cover protrusion 22e and a cover enlargement 23e. The cover 2e corresponds to a retaining member.

[0195] The cover protrusion 22e protrudes further than its periphery. The cover protrusion 22e protrudes toward the receiving space. The cover protrusion 22e has a front end surface, and the front end surface includes a cover pressing surface S51 and a cover enlargement 23e. The cover pressing surface S51 is the surface that contacts and presses against the second surface S2 of the damper 6a.

[0196] The enlarged portion 23e of the cover is inserted into the through hole H1. The enlarged portion 23e protrudes from the front end surface of the cover protrusion 22e. The enlarged portion 23e is a portion of the front end surface of the cover protrusion 22e located outside the cover pressing surface S51. For example, the enlarged portion 23e is located in a position surrounded by the cover pressing surface S51. The enlarged portion 23e has the same structure as the enlarged portion 35d of the base. Therefore, the enlarged portion 23e has a cover inclined surface S52. The cover inclined surface S52 contacts the end corner surface S8 of the damper 6a and presses the damper 6a.

[0197] When cover 2e is connected to base 3e, cover 2e presses damper 6a toward base 3e between cover 2e and base 3e. When cover 2e presses damper 6a, cover 2e and base 3e hold damper 6a.

[0198] like Figure 17 As shown, the base 3e includes a platform 34e and a base enlargement 35e. The base 3e corresponds to the support member. The platform 34e is identical to the platform 34d. The base enlargement 35e is identical to the base enlargement 35d. Therefore, the platform 34e includes a base pressing surface S21 and a base inclined surface S22. The base enlargement 35e is inserted into the through hole H1. The base pressing surface S21 contacts the first surface S1 of the damper 6a and presses the damper 6a. The base inclined surface S22 contacts the end corner surface S7 and presses the damper 6a.

[0199] Each of the cover enlargement 23e and the base enlargement 35e corresponds to a protrusion. In this embodiment, an example is adopted in which the cover 2e includes the cover enlargement 23e and the base 3e includes the base enlargement 35e. However, this disclosure is not limited thereto. It is only necessary to provide at least one of the cover enlargement 23e and the base enlargement 35e.

[0200] Each of the cap inclined surface S52 and the base inclined surface S22 corresponds to an inclined surface or an outer inclined surface. In this embodiment, an example is adopted where the cap 2e includes the cap inclined surface S52 and the base 3e includes the base inclined surface S22. However, this disclosure is not limited thereto. It is only necessary to provide at least one of the cap inclined surface S52 and the base inclined surface S22.

[0201] like Figure 17As shown, the damper 6a has an end corner surface S7 closer to the first surface S1 and an end corner surface S8 closer to the second surface S2. The end corner surface S7 is a surface pressed by the base 3e and deformed along the inclined surface S22 of the base. In this case, the end corner surface S7 can be considered as a surface formed by a portion of the first surface S1 and a portion of the inner circumferential surface S4. The end corner surface S8 is a surface pressed by the cover enlargement 23e and deformed along the inclined surface S52 of the cover. In this case, the end corner surface S8 can be considered as a surface formed by a portion of the second surface S2 and a portion of the inner circumferential surface S4. Each of the end corner surfaces S7 and S8 corresponds to an inner circumferential corner surface.

[0202] In the electronic controller 100, a damper 6a is disposed in the second insertion hole 41a. While the damper 6a is disposed in the second insertion hole 41a, the damper 6a is pressed against the base 3e by the cover 2e. That is, the damper 6a is pressed against the base 3e by connecting the cover 2e and the base 3e.

[0203] At this time, the enlarged cover portion 23e and the enlarged base portion 35e are inserted into the through hole H1 and assembled onto the damper 6a. That is, not only the first surface S1 and the second surface S2 of the damper 6a, but also the end corner surfaces S7 and S8 of the damper 6a are pressed. Therefore, the force from the cover 2e and the base 3e acts on the damper 6a not only in the thickness direction but also in the planar direction. Therefore, the force applied to the damper 6a from the enlarged cover portion 23e and the enlarged base portion 35e enlarges the diameter of the tubular body 61a of the damper, causing the damper 6a to change from the first form to the second form. Furthermore, since the force from the cover 2e and the base 3e also acts on the damper 6a in the planar direction, the holding force of the insulating base 4a can be improved.

[0204] Then, in damper 6a, the diameter of the damper tubular body 61a is enlarged, and the damper tubular body 61a presses against the insertion hole surface S11. That is, in damper 6a, the damper tubular body 61a presses against the insertion hole surface S11. In this way, damper 6a is held in circuit board 1. While damper 6a is held in circuit board 1, the stress on circuit board 1 is relaxed. In this embodiment, dampers 6b and 6c can be used instead of damper 6a.

[0205] Due to the stress applied in the thickness direction of the insulating substrate 4a, the damper 6a elastically deforms between the cover protrusion 22e and the base 34e along the thickness direction. The upper and lower parts of the damper 6a facing the insertion hole surface S11 undergo primary elastic deformation. Therefore, when stress is applied to the insulating substrate 4a along the thickness direction, the damper 6a can protect the circuit board 1.

[0206] Furthermore, in the damper 6a, a space is defined in the region surrounded by the inner peripheral surface S4. Therefore, the damper 6a readily undergoes elastic deformation along the cross direction. Thus, the damper 6a can relax not only the stress to the circuit board 1 along the thickness direction, but also the stress to the circuit board 1 along the cross direction. Therefore, the damper 6a can appropriately relax the stress to the circuit board 1.

[0207] In the electronic controller 100, the cover enlargement 23e and the base enlargement 35e are fitted to the damper 6a. Therefore, in the electronic controller 100, displacement of the cover 2e and the base 3e from the damper 6a is restricted. Thus, compared to the case where the damper 6a, cover 2e, and base 3e are displaced, the electronic controller 100 can protect the circuit board 1 from stress by properly pressing the damper 6a against the insertion hole surface S11.

[0208] (Seventh Amendment)

[0209] Reference Figure 18 The electronic controller of the seventh modification will be described. In this modification, the differences from the fourth embodiment will be mainly described. In the electronic controller of this modification, the structure of the base 3e is different from that of the fourth embodiment. However, for convenience, the same reference numerals as in the fourth embodiment are used in this modification.

[0210] like Figure 18 As shown, the base 3e includes a distance adjustment section 36e. Like the distance adjustment section 36b, the distance adjustment section 36e restricts the inner circumferential surface S4 of the damper tubular body 61a from becoming closer than desired. The electronic controller 100 of the seventh modification can achieve similar effects to the fourth embodiment.

[0211] The orientation of the base inclined surface S22 of the base enlargement 35e and the cover inclined surface S52 of the cover enlargement 23e can be appropriately changed as long as the holding force on the circuit board 1 can be increased. Similarly, for... Figure 16 The screw head 203b shown can have its orientation of the screw tilt surface S32 appropriately changed, as long as it can increase the holding force on the circuit board 1.

[0212] (Eighth Amendment)

[0213] Reference Figure 19A and 19B The damper 6e of the eighth modification will be described. Figure 19A This is a side view of damper 6e. Figure 19B It is along Figure 19A The cross-sectional view taken by line XIXB-XIXB in the diagram.

[0214] like Figure 19A and 19BAs shown, the damper 6e includes an annular tubular damper body 61e. The tubular damper body 61e, like the tubular damper body 61a, defines a through-hole H1. Similar to the tubular damper body 61a, the tubular damper body 61e includes a first surface S1, a second surface S2, an outer peripheral surface S3, and an inner peripheral surface S4. The tubular damper body 61e may be made of the same material as the tubular damper body 61a. Because there is no defined gap G1, the damper 6e is also referred to as a tubular member. The tubular damper body 61e corresponds to the tubular body.

[0215] The damper 6e can also be applied to the third embodiment, the fourth embodiment, the sixth modification, and the seventh modification. As an example, the application of the damper 6e to the fourth embodiment will be described. The damper 6e is disposed in the second insertion hole 41a. When the damper 6e is disposed in the second insertion hole 41a, the damper 6e is pressed against the base 3e by the cover 2e. That is, by connecting the cover 2e and the base 3e, the damper 6e is pressed against the base 3e.

[0216] At this point, the enlarged cover portion 23e and the enlarged base portion 35e are inserted into the through hole H1 and assembled onto the damper 6e. That is, not only the first surface S1 and the second surface S2 of the damper 6e, but also the end corner surfaces S7 and S8 of the damper 6e are pressed. Therefore, the force from the cover 2e and the base 3e acts on the damper 6e not only in the thickness direction but also in the planar direction. Therefore, the force applied to the damper 6e from the enlarged cover portion 23e and the enlarged base portion 35e enlarges the diameter of the tubular body 61e of the damper, causing the damper 6e to change from the first form to the second form. Furthermore, since the force from the cover 2e and the base 3e also acts on the damper 6a in the planar direction, the holding force of the insulating base 4a can be improved.

[0217] Then, in the damper 6e, the diameter of the damper tubular body 61e is enlarged, causing the damper tubular body 61e to press against the insertion hole surface S11. That is, in the damper 6e, the damper tubular body 61e contacts the insertion hole surface S11 using pressure. In this way, the damper 6e is held in the circuit board 1. While the damper 6e is held in the circuit board 1, the stress on the circuit board 1 is relaxed. Therefore, the eighth modification can achieve similar effects to the fourth embodiment and the seventh modification.

[0218] Although this disclosure has been described with reference to embodiments, it should be understood that this disclosure is not limited to such embodiments or structures. This disclosure includes various modifications and variations within the equivalent scope. Furthermore, while various combinations and constructions are shown in this disclosure, other combinations and constructions including more, fewer, or only a single element are also within the spirit and scope of this disclosure.
