Description

本発明は、端子及び放熱構造に関する。 The present invention relates to terminals and a heat dissipation structure.

従来、電子回路装置が有する回路側コネクタの端子、及び車両ボディが有する車両側コネクタの端子を電気的に接続する電気的接続部分を有すると共に、電子回路装置に形成された凸部、及び車両ボディが有する吸熱コネクタに設けられたＵ字型の熱受け部を接触させて熱伝導部材に熱を伝導する熱的接続部分を有する構成が開示されている（例えば特許文献１参照）。 Conventionally, it has an electrical connection portion for electrically connecting the terminal of the circuit-side connector of the electronic circuit device and the terminal of the vehicle-side connector of the vehicle body, and also has a convex portion formed on the electronic circuit device and the vehicle body. Discloses a configuration having a thermal connection portion for conducting heat to a heat conductive member by contacting a U-shaped heat receiving portion provided in the heat absorbing connector of the above (see, for example, Patent Document 1).

特開２００９－１９４２５４号公報Japanese Unexamined Patent Publication No. 2009-194254

しかし、特許文献１の構成では、電子回路装置で生じる熱を、電気的接続部分とは別の経路にある熱的接続部分及び熱伝導部材を通じて放熱するため、電気的接続部分で発生する熱も、その別経路まで誘導（迂回）して熱伝導部材から放熱することとなり、効率良く放熱しているとは言い難い。 However, in the configuration of Patent Document 1, since the heat generated in the electronic circuit device is dissipated through the thermal connection portion and the heat conductive member in a path different from the electrical connection portion, the heat generated in the electrical connection portion is also generated. , It is difficult to say that the heat is efficiently dissipated because the heat is radiated from the heat conductive member by guiding (detouring) to the other route.

本発明は、このような従来の課題を解決するためになされたものであり、その発明の目的とするところは、電気的に接続する接続部で発生する熱を、従来よりも効率良く熱伝導部材に誘導して熱伝導部材から放熱することができる端子及び放熱構造を提供することにある。 The present invention has been made to solve such a conventional problem, and an object of the present invention is to conduct heat generated in an electrically connected connection portion more efficiently than before. It is an object of the present invention to provide a terminal and a heat radiating structure capable of guiding the member to dissipate heat from the heat conductive member.

本発明に係る端子は、第１電線をカシメる電線カシメ部と、第２電線に取り付けられる相手方端子と接続される接続部と、前記相手方端子及び前記接続部の電気的な接続によって前記接続部で発生する熱又は前記第２電線から前記接続部に伝わる熱を伝導して放熱する熱伝導部材をカシメる熱伝導部材カシメ部と、を一体的に有する、ことを特徴とする。 The terminal according to the present invention is a wire caulking portion for caulking the first electric wire, a connection portion connected to a mating terminal attached to the second electric wire, and the connecting portion by electrical connection between the mating terminal and the connecting portion. It is characterized by integrally having a heat conductive member caulking portion for caulking a heat conductive member that conducts and dissipates heat generated in the above or heat transmitted from the second electric wire to the connection portion.

この端子によれば、電線カシメ部と熱伝導部材カシメ部とが一体化されているので、第２電線に取り付けられる相手方端子と接続部とが電気的に接続され、接続部で発生する熱は、接続部と一体の熱伝導部材カシメ部へと誘導されて熱伝導部材から放熱される。その結果、電気的に接続する接続部で発生する熱を、従来よりも効率良く熱伝導部材に誘導して熱伝導部材から放熱することができる。 According to this terminal, since the wire caulking portion and the heat conductive member caulking portion are integrated, the mating terminal attached to the second electric wire and the connection portion are electrically connected, and the heat generated at the connection portion is generated. , It is guided to the caulking portion of the heat conductive member integrated with the connection portion, and heat is dissipated from the heat conductive member. As a result, the heat generated in the electrically connected connection portion can be guided to the heat conductive member more efficiently than before and dissipated from the heat conductive member.

本発明によれば、電気的に接続する接続部で発生する熱を、従来よりも効率良く熱伝導部材に誘導して熱伝導部材から放熱することができる。 According to the present invention, the heat generated in the electrically connected connection portion can be guided to the heat conductive member more efficiently than before and dissipated from the heat conductive member.

［第１電線］
図２（ａ）に示されるように、第１電線１１は、被覆部１１ａと、複数本の素線により形成される導体部１１ｂと、を有する。被覆部１１ａは、導体部１１ｂを被覆している。 [First wire]
As shown in FIG. 2A, the first electric wire 11 has a covering portion 11a and a conductor portion 11b formed by a plurality of strands. The covering portion 11a covers the conductor portion 11b.

［雌型接続部］
雌型接続部１２は、第１電線１１と別体で形成されて第１電線１１と接続され、熱伝導部材３０と別体で形成されて熱伝導部材３０と接続される。また、雌型接続部１２は、導体で形成され、第１電線カシメ部１２ａと、第２電線カシメ部１２ｂ（電線カシメ部）と、筒部１２ｃ（接続部）と、熱伝導部材カシメ部１２ｄと、介在部１２ｅと、を一体的に有する。本実施形態では、雌型接続部１２は、一枚の金属板の打ち抜き、折り曲げ等の加工により形成されているが、第１電線カシメ部１２ａ、第２電線カシメ部１２ｂ、筒部１２ｃ、熱伝導部材カシメ部１２ｄ、及び介在部１２ｅの一部又は全部が個々に形成されて互いに接合されるものであっても良い。 [Female connection part]
The female connection portion 12 is formed separately from the first electric wire 11 and connected to the first electric wire 11, and is formed separately from the heat conductive member 30 and connected to the heat conductive member 30. Further, the female connection portion 12 is formed of a conductor, and has a first wire caulking portion 12a, a second electric wire caulking portion 12b (electric wire caulking portion), a cylinder portion 12c (connection portion), and a heat conductive member caulking portion 12d. And the intervening portion 12e are integrally provided. In the present embodiment, the female connection portion 12 is formed by punching, bending, or the like of a single metal plate, but the first electric wire caulking portion 12a, the second electric wire caulking portion 12b, the tubular portion 12c, and heat. A part or all of the caulking portion 12d and the intervening portion 12e of the conductive member may be individually formed and joined to each other.

第１電線カシメ部１２ａは、第１電線１１の被覆部１１ａをカシメる部分である。第２電線カシメ部１２ｂは、第１電線１１の導体部１１ｂをカシメる部分であり、第２電線カシメ部１２ｂが第１電線１１の導体部１１ｂをカシメることにより雌型接続部１２と第１電線１１とが電気的に接続される。 The first electric wire caulking portion 12a is a portion for caulking the covering portion 11a of the first electric wire 11. The second electric wire caulking portion 12b is a portion for caulking the conductor portion 11b of the first electric wire 11, and the second electric wire caulking portion 12b crimps the conductor portion 11b of the first electric wire 11 to the female connection portion 12 and the second. 1 The electric wire 11 is electrically connected.

図２（ｂ）に示されるように、筒部１２ｃは、筒部１２ｃに後述する雄型接続部２２の筒部２２ｃが挿抜される方向を挿抜方向Ｌとした場合に、挿抜方向Ｌに貫通する孔を有する筒状の部分であり、雄型接続部２２の筒部２２ｃと接続される。筒部１２ｃの内側面は、挿抜方向Ｌに広がる曲面状の第１面Ａ１を有する。筒部１２ｃに筒部２２ｃが挿入されると、筒部１２ｃの第１面Ａ１と、筒部２２ｃの外側面に挿抜方向Ｌに広がる第２面Ａ２と、が面接触する。第１面Ａ１と第２面Ａ２とは双方とも挿抜方向Ｌに広がっていて平行であるので、広い面積で対向することができ、双方間の熱抵抗が抑制される。
また、筒部１２ｃの内径は、筒部２２ｃの外径と略同一に設定されている。また、筒部１２ｃの内側面と筒部２２ｃの外側面との間には、熱伝導性を有するグリスや柔軟性及び熱伝導性を有する他の材料が挿入されても良い。このため、筒部１２ｃの内側に対して、筒部２２ｃを面接触させながら挿すことも抜くこともできる。 As shown in FIG. 2B, the cylinder portion 12c penetrates in the insertion / removal direction L when the direction in which the cylinder portion 22c of the male connecting portion 22 described later is inserted into the cylinder portion 12c is the insertion / removal direction L. It is a tubular portion having a hole to be formed, and is connected to the tubular portion 22c of the male connecting portion 22. The inner surface of the tubular portion 12c has a curved first surface A1 extending in the insertion / extraction direction L. When the cylinder portion 22c is inserted into the cylinder portion 12c, the first surface A1 of the cylinder portion 12c and the second surface A2 extending in the insertion / extraction direction L on the outer surface of the cylinder portion 22c come into surface contact with each other. Since both the first surface A1 and the second surface A2 spread in the insertion / extraction direction L and are parallel to each other, they can face each other in a wide area, and the thermal resistance between them is suppressed.
Further, the inner diameter of the tubular portion 12c is set to be substantially the same as the outer diameter of the tubular portion 22c. Further, grease having thermal conductivity or another material having flexibility and thermal conductivity may be inserted between the inner side surface of the tubular portion 12c and the outer surface of the tubular portion 22c. Therefore, the tubular portion 22c can be inserted or removed while being in surface contact with the inside of the tubular portion 12c.

図２（ａ）に示す熱伝導部材カシメ部１２ｄは、熱伝導部材３０の絶縁部３２をカシメる部分である。また、本実施形態では、熱伝導部材カシメ部１２ｄは、円筒状に形成されている。なお、熱伝導部材カシメ部１２ｄは、面状や楕円形状等のように形成されても良い。いずれの形状で形成されても絶縁部３２との接触面積を広く取ることが望ましい。熱伝導部材カシメ部１２ｄは、筒部１２ｃと第２電線カシメ部１２ｂとの間に配置される。熱伝導部材カシメ部１２ｄは、コネクタハウジング５１のキャビティ５１ｂの外部に配置されている（図１（ａ）参照）。 The heat conductive member caulking portion 12d shown in FIG. 2A is a portion for caulking the insulating portion 32 of the heat conductive member 30.

The heat conductive member caulked portion 12d may be formed in a planar shape, an elliptical shape, or the like. Regardless of the shape, it is desirable to have a wide contact area with the insulating portion 32. The heat conductive member caulking portion 12d is arranged between the tubular portion 12c and the second electric wire caulking portion 12b. The heat conductive member caulking portion 12d is arranged outside the cavity 51b of the connector housing 51 (see FIG. 1A).

［熱伝導部材］
図２（ａ）に示す熱伝導部材３０は、図１（ｂ）のような第１電線１１に取り付けられた雌型接続部１２と第２電線２１に取り付けられた雄型接続部２２との電気的な接続によって筒部１２ｃで発生する熱又は第２電線２１から筒部１２ｃに伝わる熱を伝導して放熱する部材である。熱伝導部材３０は、熱伝導部材本体３１と、絶縁部３２と、を有する。筒部１２ｃで発生する熱としては、雌型接続部１２の筒部１２ｃと雄型接続部２２の筒部２２ｃとの通電時の接触抵抗により発生するような熱が想定される。また、第２電線２１から筒部１２ｃに伝わる熱としては、第２電線２１に取り付けられた電気機器等の発熱部から第２電線２１を通って筒部１２ｃに伝わるような熱が想定される。 [Heat conduction member]

The heat conductive member 30 has a heat conductive member main body 31 and an insulating portion 32. As the heat generated in the cylinder portion 12c, it is assumed that the heat is generated by the contact resistance between the cylinder portion 12c of the female connection portion 12 and the cylinder portion 22c of the male connection portion 22 when energized. Further, as the heat transferred from the second electric wire 21 to the cylinder portion 12c, it is assumed that the heat is transferred from the heat generating portion of the electric device or the like attached to the second electric wire 21 to the cylinder portion 12c through the second electric wire 21. ..

As shown in FIG. 1 (b), the second electric wire 21 is electrically connected to the first electric wire 11 by connecting the male connecting portion 22 to the female connecting portion 12. As shown in FIG. 2A, the second electric wire 21 has a covering portion 21a and a conductor portion 21b formed by a plurality of strands. The covering portion 21a covers the conductor portion 21b.

［雄型接続部］
雄型接続部２２は、導体で形成され、第１電線カシメ部２２ａと、第２電線カシメ部２２ｂと、筒部２２ｃと、介在部２２ｄと、を一体的に有する。本実施形態では、雄型接続部２２は、一枚の金属板の打ち抜き、折り曲げ等の加工により形成されているが、第１電線カシメ部２２ａ、第２電線カシメ部２２ｂ、筒部２２ｃ、及び介在部２２ｄの一部又は全部が個々に形成されて互いに接合されるものであっても良い。 [Male connection]
The male connection portion 22 is formed of a conductor and integrally includes a first electric wire caulking portion 22a, a second electric wire caulking portion 22b, a tubular portion 22c, and an intervening portion 22d. In the present embodiment, the male connection portion 22 is formed by punching, bending, or the like of a single metal plate, but the first electric wire caulking portion 22a, the second electric wire caulking portion 22b, the tubular portion 22c, and the tubular portion 22c. Part or all of the intervening portion 22d may be individually formed and joined to each other.

図１（ａ）及び図１（ｂ）に示されるように、第１電線１１に取り付けられた雌型接続部１２は、コネクタハウジング５１に設けられている。コネクタハウジング５１は、複数の区画壁５１ａを有している。複数の区画壁５１ａの面によってキャビティ５１ｂが形成されている。
キャビティ５１ｂには、第１電線１１、熱伝導部材３０、及び雌型接続部１２の第１電線カシメ部１２ａが収容されている。
これに対して、キャビティ５１ｂの外部に、第２電線カシメ部１２ｂ、筒部１２ｃ、熱伝導部材カシメ部１２ｄ、及び介在部１２ｅが配置されている。
このように、熱伝導部材カシメ部１２ｄ及び介在部１２ｅがコネクタハウジング５１の外部にあるため、熱伝導部材カシメ部１２ｄ及び介在部１２ｅをキャビティ５１ｂの内部に収納するために区画壁５１ａを一部くり抜く等の複雑な加工をする必要がなくなる。 As shown in FIGS. 1A and 1B, the female connection portion 12 attached to the first electric wire 11 is provided in the connector housing 51.

On the other hand, outside the cavity 51b, a second electric wire caulking portion 12b, a tubular portion 12c, a heat conductive member caulking portion 12d, and an intervening portion 12e are arranged.
As described above, since the heat conductive member caulking portion 12d and the intervening portion 12e are outside the connector housing 51, the partition wall 51a is partially accommodated in order to house the heat conductive member caulking portion 12d and the intervening portion 12e inside the cavity 51b.

The heat conductive member caulking portion 12d for caulking is integrally provided.

この構成によれば、第２電線カシメ部１２ｂと熱伝導部材カシメ部１２ｄとが一体化されているので、第２電線２１に取り付けられる雄型接続部２２と筒部１２ｃとが電気的に接続され、筒部１２ｃで熱が発生する熱又は第２電線２１から筒部１２ｃに伝わる熱は、筒部１２ｃと一体の熱伝導部材カシメ部１２ｄへと誘導されて熱伝導部材３０から放熱される。その結果、電気的に接続する筒部１２ｃで発生する熱又は筒部１２ｃに伝わる熱を、従来よりも効率良く熱伝導部材３０に誘導して熱伝導部材３０から放熱することができる。 According to this configuration, since the second electric wire caulking portion 12b and the heat conductive member caulking portion 12d are integrated, the male connecting portion 22 attached to the second electric wire 21 and the tubular portion 12c are electrically connected. The heat generated in the cylinder portion 12c or the heat transferred from the second electric wire 21 to the cylinder portion 12c is guided to the heat conduction member caulking portion 12d integrated with the cylinder portion 12c and dissipated from the heat conduction member 30. .. As a result, the heat generated in the electrically connected tubular portion 12c or the heat transferred to the tubular portion 12c can be guided to the heat conductive member 30 more efficiently than before and dissipated from the heat conductive member 30.

加えて、雌型接続部１２の筒部１２ｃという１か所の部分が雄型接続部２２と接続されれば、第２電線２１及び第１電線１１が電気的に接続されると同時に、第２電線２１から第１電線１１に伝わる熱の放熱経路を確保することができる。また、熱伝導部材３０が熱伝導部材カシメ部１２ｄによりカシメられる構成であるために、接触面積が大きく確保され、筒部１２ｃから熱伝導部材３０への熱抵抗が抑制される。 In addition, if one portion of the female connecting portion 12 called the tubular portion 12c is connected to the male connecting portion 22, the second electric wire 21 and the first electric wire 11 are electrically connected, and at the same time, the second electric wire 21 and the first electric wire 11 are electrically connected. It is possible to secure a heat dissipation path for heat transmitted from the two electric wires 21 to the first electric wire 11. Further, since the heat conductive member 30 is caulked by the heat conductive member caulking portion 12d, a large contact area is secured and the thermal resistance from the tubular portion 12c to the heat conductive member 30 is suppressed.

また、本実施形態の放熱構造１は、雌型接続部１２と、雌型接続部１２の第１電線カシメ部１２ａ及び第２電線カシメ部１２ｂにカシメられる第１電線１１と、雌型接続部１２の熱伝導部材カシメ部１２ｄにカシメられる熱伝導部材３０と、を備え、熱伝導部材３０は、熱伝導部材本体３１と、熱伝導部材本体３１に接触して設けられる絶縁部３２と、を有し、熱伝導部材カシメ部１２ｄは、絶縁部３２をカシメる。この構成によれば、第２電線２１と熱伝導部材３０との間で電気的な回路が構成されることを抑制し、短絡や漏電による機器の動作異常を抑制することができる。 Further, in the heat dissipation structure 1 of the present embodiment, the female connecting portion 12, the first electric wire 11 caulked by the first wire caulking portion 12a and the second electric wire caulking portion 12b of the female connecting portion 12, and the female connecting portion The heat conductive member 30 is provided with a heat conductive member 30 crimped to the heat conductive member caulking portion 12d, and the heat conductive member 30 includes a heat conductive member main body 31 and an insulating portion 32 provided in contact with the heat conductive member main body 31. The heat conductive member caulking portion 12d has the insulating portion 32 caulked. According to this configuration, it is possible to suppress the formation of an electric circuit between the second electric wire 21 and the heat conductive member 30, and to suppress an operation abnormality of the device due to a short circuit or an electric leakage.

また、本実施形態の放熱構造１では、筒部１２ｃと第２電線カシメ部１２ｂとの間に熱伝導部材カシメ部１２ｄが配置される。この構成によれば、第２電線２１から筒部１２ｃに伝導した熱が第１電線１１に伝導する前に、熱を熱伝導部材３０に逃がすことができる。 Further, in the heat dissipation structure 1 of the present embodiment, the heat conductive member caulking portion 12d is arranged between the tubular portion 12c and the second electric wire caulking portion 12b. According to this configuration, the heat conducted from the second electric wire 21 to the tubular portion 12c can be released to the heat conductive member 30 before being conducted to the first electric wire 11.

また、本実施形態の放熱構造１では、キャビティ５１ｂを有するコネクタハウジング５１を備え、熱伝導部材カシメ部１２ｄは、キャビティ５１ｂの外部に配置されている。この構成によれば、コネクタハウジング５１の形状を特殊な形状で形成する必要をなくすることができる。 Further, in the heat dissipation structure 1 of the present embodiment, the connector housing 51 having the cavity 51b is provided, and the heat conductive member caulking portion 12d is arranged outside the cavity 51b. According to this configuration, it is possible to eliminate the need to form the shape of the connector housing 51 with a special shape.
