Description
本発明は、筐体に内挿されたプリント基板を外部の物体から保護する電子制御装置に関するものである。 The present invention relates to an electronic control device that protects a printed circuit board inserted in a housing from an external object.
従来、スマートキーレスエントリやイモビライザ用の電子制御装置においては、筐体を袋状に成型し、プリント基板を筐体に内挿したものが知られている（例えば特許文献１参照）。 Conventionally, electronic control devices for smart keyless entry and immobilizer are known in which a casing is molded into a bag shape and a printed circuit board is inserted into the casing (see, for example, Patent Document 1).
図７は、従来の電子制御装置を説明する断面図である。なお、図７で示すＸＹＺ軸は、Ｘ軸正方向が電子制御装置の正面から背面に向かう方向を示し、Ｙ軸正方向が電子制御装置の左面から右面に向かう方向を示し、Ｚ軸正方向が電子制御装置の底面から上面に向かう方向を示す。ＸＹＺ軸を用いて表すと、図７は、電子制御装置をＸＺ平面で切ったときにＹ軸負方向から見たときの断面図である。図８は、図７の電子制御装置の正面図である。ＸＹＺ軸を用いて表すと、図８は、電子制御装置をＸ軸正方向から見たときの正面図である。図９は、図７の点線部分Ａの拡大図である。 FIG. 7 is a cross-sectional view illustrating a conventional electronic control device. 7, the X-axis positive direction indicates the direction from the front to the back of the electronic control device, the Y-axis positive direction indicates the direction from the left surface to the right surface of the electronic control device, and the Z-axis positive direction. Indicates the direction from the bottom to the top of the electronic control unit. When expressed using the XYZ axis, FIG. 7 is a cross-sectional view of the electronic control device viewed from the negative direction of the Y axis when cut along the XZ plane. FIG. 8 is a front view of the electronic control unit of FIG. When expressed using the XYZ axes, FIG. 8 is a front view of the electronic control device viewed from the positive direction of the X axis. FIG. 9 is an enlarged view of a dotted line portion A in FIG.
図７、図８に示すように、電子制御装置は、第１の筐体１と、この第１の筐体１に内挿されるプリント基板２と、第１の筐体１に設けられてプリント基板２を狭持する狭持部３と、プリント基板２上の図示しない電子回路部品と一端が電気的に接続する金属端子４と、プリント基板２上に設けて金属端子４の他端を保護するコネクタ５と、第１の筐体１の正面側に設けられた第１の開口部を塞ぐ第２の筐体６とを備える。 As shown in FIGS. 7 and 8, the electronic control unit is provided with a first casing 1, a printed circuit board 2 inserted in the first casing 1, and a print provided on the first casing 1. A holding part 3 for holding the board 2, a metal terminal 4 electrically connected to an electronic circuit component (not shown) on the printed board 2, and a metal terminal 4 provided on the printed board 2 to protect the other end of the metal terminal 4 And a second housing 6 that closes the first opening provided on the front side of the first housing 1.
プリント基板２は、第１の筐体１の底面側（ＸＹＺ軸を用いて表すとＺ軸の負方向側）に配置されている。第１の筐体１と第２の筐体６は、それぞれ図示しないロック爪とロック部を有して互いに嵌合する。コネクタ５は、正面側に外周部５Ａとこの外周部５Ａに囲まれた開口部５Ｂを有する。金属端子４の他端はこの開口部５Ｂから露出する。第２の筐体６は、第２の開口部とこの開口端からＸ軸の負方向に突出した突出部７を有する。第２の筐体６に設けられた第２の開口部からコネクタ５が突出する。突出部７は、第２の筐体６の開口から突出したコネクタ５の上下の面、および、左右の面を取り囲んでコネクタ５を保護する。コネクタ５と突出部７との間には、第２の筐体６に設けられた第２の開口部の一部である隙間８が設けられている。この隙間８は、コネクタ５の外周部５Ａと突出部７の内周部７Ａとの間に設けられている。針金等の外来固形物から電子制御装置を保護するため、この隙間８の長さは、所定の値以下に設定することが国際規格で決められている（例えば非特許文献１を参照）。このような規格が定められているのは、図９の一点鎖線１０に示すように、針金９が隙間８に差し込まれて金属端子４やプリント基板２上の図示しない電子回路と接触して電子制御装置が誤動作したり故障したりするのを防止するためである。 The printed circuit board 2 is disposed on the bottom surface side of the first housing 1 (in the negative direction side of the Z axis when expressed using the XYZ axes). The first casing 1 and the second casing 6 have a lock claw and a lock portion (not shown), and are fitted to each other. The connector 5 has an outer peripheral portion 5A and an opening 5B surrounded by the outer peripheral portion 5A on the front side. The other end of the metal terminal 4 is exposed from the opening 5B. The second housing 6 has a second opening and a protrusion 7 protruding from the opening end in the negative direction of the X axis. The connector 5 protrudes from a second opening provided in the second housing 6. The protrusion 7 surrounds the upper and lower surfaces of the connector 5 protruding from the opening of the second housing 6 and the left and right surfaces to protect the connector 5. A gap 8 that is a part of the second opening provided in the second housing 6 is provided between the connector 5 and the protruding portion 7. The gap 8 is provided between the outer peripheral portion 5 </ b> A of the connector 5 and the inner peripheral portion 7 </ b> A of the protruding portion 7. In order to protect the electronic control device from foreign solids such as a wire, the length of the gap 8 is determined by an international standard to be set to a predetermined value or less (see, for example, Non-Patent Document 1). Such a standard is defined as shown in a one-dot chain line 10 in FIG. 9 in which the wire 9 is inserted into the gap 8 and comes into contact with an electronic circuit (not shown) on the metal terminal 4 or the printed circuit board 2. This is to prevent the control device from malfunctioning or failing.
電子制御装置は、隙間８の長さを所定値以下にすることが国際規格で求められている。例えば、スマートキーレスエントリやイモビライザ等のセキュリティ関連の電子制御装置の場合、隙間８の長さは１．０ｍｍ以下に設定されている。しかし、この隙間８の長さは、第１の筐体１、プリント基板２、狭持部３、コネクタ５、第２の筐体６といった多くの部品の製造ばらつきに依存する。このため、各部品の較差を厳しく設定しなければならず、隙間８の長さを国際規格の値以下に設計することが困難であった。特に、コネクタ数の増加に伴い、この設計はさらに困難になる。 The electronic control device is required by international standards to set the length of the gap 8 to a predetermined value or less. For example, in the case of a security-related electronic control device such as a smart keyless entry or an immobilizer, the length of the gap 8 is set to 1.0 mm or less. However, the length of the gap 8 depends on manufacturing variations of many components such as the first housing 1, the printed circuit board 2, the holding portion 3, the connector 5, and the second housing 6. For this reason, it is necessary to set the range of each part strictly, and it is difficult to design the length of the gap 8 to be equal to or less than the international standard value. In particular, this design becomes more difficult as the number of connectors increases.
本発明は、このような従来の問題を解決するためになされたもので、針金等の外来固形物からの保護と設計の自由度の向上とを両立することができる電子制御装置を提供することを目的とする。 The present invention has been made to solve such a conventional problem, and provides an electronic control device capable of achieving both protection from foreign solid matter such as a wire and improvement in design freedom. With the goal.
上記目的を達成するために本発明は、突出部の先端から内側に張り出したフランジ部を備え、突出部がコネクタの先端よりも外側に突出し、フランジ部の先端がコネクタの外周よりも中心方向に張り出したことを特徴とする。 In order to achieve the above object, the present invention includes a flange portion that protrudes inward from the tip of the protrusion, the protrusion protrudes outward from the tip of the connector, and the tip of the flange portion extends in the center direction from the outer periphery of the connector. It is characterized by overhanging.
本発明の電子制御装置によれば、針金等の外来固形物からの保護と設計の自由度の向上とを両立することができるという効果を奏する。 According to the electronic control device of the present invention, there is an effect that it is possible to achieve both protection from foreign solid matter such as a wire and improvement in design freedom.
（実施の形態１）
以下、本発明の実施の形態１の電子制御装置について図面を用いて説明する。本発明の電子制御装置のうち、従来の図７〜図９と同じ構成については詳細な説明を省略し、同じ符号を用いる。
(Embodiment 1)
Hereinafter, an electronic control device according to a first embodiment of the present invention will be described with reference to the drawings. In the electronic control device of the present invention, detailed description of the same configuration as that of the conventional FIGS. 7 to 9 is omitted, and the same reference numerals are used.
図１は本発明の実施の形態１における電子制御装置の断面図である。図２は、図１の電子制御装置の正面図である。ＸＹＺ軸を用いて表すと、図２は、図１の電子制御装置をＸ軸の正方向に見たときの正面図である。図３は、図１の点線部分Ｂの拡大図である。 FIG. 1 is a cross-sectional view of the electronic control unit according to Embodiment 1 of the present invention. FIG. 2 is a front view of the electronic control unit of FIG. When expressed using the XYZ axes, FIG. 2 is a front view of the electronic control device of FIG. 1 when viewed in the positive direction of the X axis. FIG. 3 is an enlarged view of a dotted line portion B in FIG.
図１、図２に示されるように、突出部７はコネクタ５の先端よりも外側に突出する。ＸＹＺ軸を用いて表すと、突出部７はコネクタ５の先端よりもＸ軸の負方向に向かって突出する。 As shown in FIGS. 1 and 2, the protruding portion 7 protrudes outward from the tip of the connector 5. When expressed using the XYZ axes, the protrusion 7 protrudes in the negative direction of the X axis from the tip of the connector 5.
第２の筐体６は、突出部７の先端に設けられたフランジ部１１を有する。フランジ部１１は、突出部７から内側に張り出す。このフランジ部１１は、突出部７の先端から、突出部７の筒の中心方向に向かって張り出す。フランジ部１１は、この内側に張り出した面である先端部１１Ａを有する。 The second housing 6 has a flange portion 11 provided at the tip of the protruding portion 7. The flange portion 11 projects inward from the protruding portion 7. The flange portion 11 projects from the tip of the protruding portion 7 toward the center of the cylinder of the protruding portion 7. The flange part 11 has the front-end | tip part 11A which is the surface protruded inside.
図３に示すように、フランジ部１１は、突出部７の内側に長さＬ１張り出している。このため、コネクタ５の外周部５Ａと突出部７の内周部７Ａとの間の隙間８の長さＷ１が国際規格で定められた所定の値以上であっても、フランジ部１１の先端部１１Ａとコネクタ５の外周部５Ａとの間にＸ方向の隙間がなくなる。したがって、図３に示すように、フランジ部１１の先端部１１Ａとコネクタ５の外周部５Ａとは、Ｘ方向に長さＤ１の壁面が重複している。なお、突出部７から張り出すフランジ部１１の長さＬ１は各部分で異なる値であってもよい。 As shown in FIG. 3, the flange portion 11 projects a length L 1 inside the protruding portion 7. Therefore, also the length W 1 of the gap 8 between the outer peripheral portion 5A of the connector 5 and the inner peripheral portion 7A of the protrusions 7 is not more than a predetermined value determined by international standards, the tip of the flange portion 11 There is no gap in the X direction between the portion 11A and the outer peripheral portion 5A of the connector 5. Accordingly, as shown in FIG. 3, the outer peripheral portion 5A of the distal end portion 11A and the connector 5 of the flange portion 11, the wall surface of the length D 1 in the X direction is duplicated. Note that the length L 1 of the flange portion 11 protruding from the protruding portion 7 may be a different value in each portion.
また、図２に示すように、フランジ部１１は突出部７の筒を構成する外周全体から筒の内側に張り出している。したがって、図２に示すように、フランジ部１１が隙間８の長さＷ１よりも大きい長さＬ１張り出すことによって、ＹＺ平面において、コネクタ５の上下左右全ての方向に存在する隙間８は覆われて見えなくなる。このため、隙間８の長さＷ１が国際規格で定められた値以上であっても針金９等の固形外来物がどの隙間８からも通らず、金属端子４やプリント基板上の図示しない電子回路に接触することを防止することができる。 Further, as shown in FIG. 2, the flange portion 11 protrudes from the entire outer periphery constituting the tube of the protruding portion 7 to the inside of the tube. Therefore, as shown in FIG. 2, the flange portion 11 protrudes a length L 1 larger than the length W 1 of the gap 8, so that the gap 8 existing in all directions of the connector 5 in the YZ plane is It is covered and disappears. For this reason, even if the length W 1 of the gap 8 is equal to or greater than the value determined by the international standard, solid foreign matter such as the wire 9 does not pass through any gap 8, and the electronic terminals (not shown) on the metal terminals 4 and the printed circuit board. Contact with the circuit can be prevented.
なお、コネクタ５の開口部５Ｂに図示しないソケットを挿入可能にするため、フランジ部１１の先端部１１Ａは、コネクタ５の開口部５Ｂの外周部よりも外側に張り出されている。したがって、（フランジ部１１の張り出した長さＬ１）は、（コネクタ５の外周部５Ａと突出部７の内周部７Ａとの間の隙間８の長さＷ１）より大きく、（コネクタ５の外周部５Ａと突出部７の内周部７Ａとの間の隙間８の長さＷ１）と（コネクタ５の外周部５Ａの厚みＨ１）の和より小さい。 In addition, in order to allow a socket (not shown) to be inserted into the opening 5B of the connector 5, the front end portion 11A of the flange portion 11 projects outward from the outer peripheral portion of the opening 5B of the connector 5. Therefore, (the length L 1 at which the flange portion 11 protrudes) is larger than (the length W 1 of the gap 8 between the outer peripheral portion 5A of the connector 5 and the inner peripheral portion 7A of the protruding portion 7), and (the connector 5 Less than the sum of the length W 1 ) of the gap 8 between the outer peripheral portion 5A and the inner peripheral portion 7A of the protrusion 7 and (the thickness H 1 of the outer peripheral portion 5A of the connector 5).
このため、隙間８自体の長さが国際規格で定められた値以上であっても、針金等の固形外来物がどの隙間８からも通らず、金属端子４やプリント基板上の図示しない電子回路に接触することを防止することができる。また、各部品の製造の際に、コネクタ５の外周部５Ａと突出部７の内周部７Ａとの間の隙間８の長さＷ１を以上にすることが許容されるので、歩留まりを向上することができる。以上より、本発明の実施の形態１の電子制御装置によれば、電子制御装置の保護と設計の自由度の向上とを両立させることができる。なお、本実施形態では、フランジ部１１の先端部１１Ａがコネクタの外周部５Ａよりも外側に張り出していても、コネクタ５の外周部５Ａとフランジ部１１の先端部１１Ａとの間の長さＤ１が国際規格で定められた所定値（例えばスマートキーレスエントリシステムやイモビライザ等のセキュリティ関連装置では１．０ｍｍ）以下の場合、コネクタ５の外周部５Ａとフランジ部１１の先端部１１Ａとの間に隙間が無いものとしてもよい。
（実施の形態２）
実施の形態１では、フランジ部１１は突出部７の筒を構成する外周全体から筒の内側に張り出していたが外周の一部のみ張り出してもよい。本実施の形態の電子制御装置のうち、従来の図７〜図９、または、実施の形態１と同じ構成については詳細な説明を省略し、同じ符号を用いる。
For this reason, even if the length of the gap 8 itself is not less than the value determined by the international standard, solid foreign substances such as wires do not pass through any gap 8, and an electronic circuit (not shown) on the metal terminal 4 or the printed circuit board. Can be prevented from touching. Further, in the manufacture of the parts, since it is allowed to be at least the length W 1 of the gap 8 between the outer peripheral portion 5A of the connector 5 and the inner peripheral portion 7A of the projecting portion 7, increase the yield can do. As described above, according to the electronic control device of the first embodiment of the present invention, it is possible to achieve both protection of the electronic control device and improvement in design freedom. In the present embodiment, the length D between the outer peripheral portion 5A of the connector 5 and the front end portion 11A of the flange portion 11 even if the front end portion 11A of the flange portion 11 projects outward from the outer peripheral portion 5A of the connector. When 1 is equal to or less than a predetermined value (for example, 1.0 mm for a security-related device such as a smart keyless entry system or an immobilizer) defined by an international standard, between the outer peripheral portion 5A of the connector 5 and the tip portion 11A of the flange portion 11 It is good also as a thing without a clearance gap.
