Description

【0001】
【発明の属する技術分野】
本発明はアース端子に関し、特に、互いに間隔を空けて設けられた複数本のアース用スタッドボルトに機器側からの複数のアース電線をアース接続する為のアース端子に関する。
【0002】
【従来の技術】
従来より、コンピュータ等を内蔵した車載用電気機器等では、誤動作防止の為に車体に確実なアースをとる必要がある。
その為の構造としては、アースパネル(車体パネル等)上において所定の間隔を空けた所定のアース位置にねじ込まれる複数本のスタッドボルトにより固定されるアース端子に、それぞれの電子機器からの複数のアース電線を接続し、複数位置でアース接続を行うものがある。
【0003】
図3は、このような複数位置でアース接続を行う為の従来のアース端子の概略構成を示している。
ここに示したアース端子1は、互いに間隔を空けて設けられた2本のアース用スタッドボルト3に、それぞれ電子機器側からの2本のアース電線Gをアース接続するアース端子であり、前記アース用スタッドボルト3を挿通する2個の貫通穴6,6を穿設した組付け部2と、前記アース電線Gの端部を圧着接続する2箇所の電線接続部5,5とが一体に設けられている。
【0004】
そこで先ず、前記アース端子1は、図3(a)に示すように、略矩形状の組付け部2の一端縁に適宜延設された2箇所の電線接続部5に、アース電線Gの端部が圧着接続される。該電線接続部5は、一対の心線加締片5a,5aと、一対の電線被覆加締片5b,5bとからなり、図示しない加締め装置により各アース電線Gの端部が圧着される。
【0005】
次に、前記アース端子1は、図3(b)に示すように、車体パネル4上において所定の間隔をもって設けられた取付孔7にねじ込まれる2本のアース用スタッドボルト3の締付けによって固定される。
即ち、前記アース端子1は、1本のアース用スタッドボルトに複数のLA端子を共締めする場合に比べて、車体パネル4に対する接触面積を広くでき、良好なアース接続を得ることができると共に、確実に固定される。
【0006】
ところで、電線端部を電線接続部に圧着接続する場合、導体が多心の撚線構造の場合、外周側に位置する心線は直接接続端子に接触するため導通が得やすいが、中心側に位置する心線は外周側の心線を介して接続端子に接触することになるので、内周側の心線と外周側の心線とで接触抵抗に差異が生じ、電線接続部における電気抵抗の増大を招く可能性があった。
【0007】
そこで、最近では、電線接続部における接触抵抗のばらつきを防止するために、電線接続部において導体を溶接した溶接端子が用いられている(例えば、特許文献1参照)。
図4に示したように、溶接端子10は、端子基板部11の先端側に電気接続部であるアース止め穴(貫通穴)13を有すると共に後端側に一対の電線被覆加締片15,15を有しており、溶接部である端子基板部11の中間部両側には一対の側壁12,12が垂設されて断面コ字状とされている。
【0008】
そして、溶接部となる前記端子基板部11の側壁12,12の間に、アース電線Gの絶縁被覆17を剥がして露出させた導体部分18をセットする。
この状態で、振動ホーン19を上方から前記導体部分18に押圧し、該振動ホーン19を超音波振動させると、超音波の振動エネルギーによって発生する局所的な振動発熱で導体部分18の各心線が溶融する。
【0009】
この際、前記側壁12,12は、振動ホーン19により押圧された導体部分18の各心線がばらけるのを阻止し、超音波の振動エネルギーが伝わり難くなるのを防止する。
これにより、アース電線Gの導体部分18が、溶接端子10の端子基板部11に一体となって溶着固定される。
【0010】
従って、上記溶接端子100は、端子基板部に一体成形した心線加締片によって電線の導体部分を加締めて圧着固定していた圧着端子に比べ、電気的接続の信頼性を高めることができる。
尚、前記電線106の導体部分108を前記溶接端子100の端子基板部101に溶接固定する溶接法としては、振動ホーン110を備えた超音波溶接法に限らず、溶接用の電極で導体部分108を端子基板部101に溶接固定する電気抵抗溶接法や、レーザ溶接等を用いることもできる。

【発明が解決しようとする課題】
しかしながら、複数の貫通穴6が穿設された大型の組付け部2に複数の電線接続部が一体に設けられた上記アース端子1は、図4に示した溶接端子10に比べて熱容量が大きく、放熱面積も広いので、振動ホーンやレーザ等による熱エネルギーが電線接続部に集中し難い。
そこで、アース端子1における各電線接続部にアース電線Gの導体を溶接しようとしても、容易には電線接続部と導体部分とが溶着せず、電線接続部における接触不良を生じる虞があった。
【0013】
従って、本発明の目的は上記課題を解消することに係り、互いに間隔を空けて設けられた複数本のアース用スタッドボルトに複数のアース電線をアース接続するアース端子でありながら、電線接続部にアース電線の導体を溶着固定することができる良好なアース端子を提供することである。
【0014】
【課題を解決するための手段】
本発明の上記目的は、互いに間隔を空けて設けられた複数本のアース用スタッドボルトに複数本のアース電線をアース接続する為のアース端子であって、
前記各アース電線の端部が溶着固定された電線接続部と、前記各アース用スタッドボルトが挿通される複数の貫通穴が穿設された組付け板部と、をそれぞれ備えた複数の組合せ端子金具が、これら各組合せ端子金具における組付け板部の複数の貫通穴を互いに一致させるように係合合体させられた後、前記複数本のアース用スタッドボルトにより締結固定されることを特徴とするアース端子により達成される。
【0015】
上記構成のアース端子によれば、互いに係合合体させられる前の各組合せ端子金具は、それぞれ複数の貫通穴が穿設された組付け板部毎に1箇所の電線接続部を備えた構成であり、複数の貫通穴が穿設された組付け板部に複数の電線接続部が一体に設けられた従来のアース端子にくらべ、各組合せ端子金具は、熱容量が小さく、放熱面積も狭くできる。
そこで、各組合せ端子金具における前記電線接続部と前記アース電線の導体部分とを、容易に溶着することができる。
【0016】
そして、それぞれ別体に形成された複数の組合せ端子金具を係合合体させることにより、互いに間隔を空けて設けられた複数本のアース用スタッドボルトに複数のアース電線をアース接続する為のアース端子を形成することができる。
即ち、上記アース端子は、車体パネル等に対する接触面積が広く、固定が確実なアース接続を得ることができると共に、電線接続部とアース電線との電気的接続の信頼性をも高めることができる。
【0017】

【0022】
前記組付け板部63は、一対の貫通穴67,68を結ぶ方向に細長い単純な帯板状であり、幅寸法wが上記組付け板部43と同様に必要最小限に設定されている。
前記組付け板部63における連結部63a(一対の貫通穴67,68間の部分)は、前記組付け板部43の連結部43a上に面接触するように、該連結部43aと面一に連なる平板状に仕上げられている。
前記電線接続部65は、アース電線Gの絶縁被覆17を加締める一対の電線被覆加締め片72,72と、溶接されるアース電線Gの導体部分18を位置決めするべく両側縁に垂設された一対の側壁77,77とを備えている。
【0023】
更に、これら第1及び第2の組合せ端子金具41,61における各組付け板部43,63の各取付穴47,48、67,68の外側縁には、組付け板部43,63相互を積層状態に組み合わせた時に、相手の組付け板部を押さえる係合突片49,50,69,70が、プレス成形によって一体形成されている。
【0024】
即ち、本実施形態のアース端子31によれば、互いに係合合体させられる前の各第1及び第2組合せ端子金具41,61は、図1に示したように、それぞれ2個の貫通穴47,48及び67,68が穿設された組付け板部43,63毎に1箇所の電線接続部45及び65を備えた構成であり、2個の貫通穴6,6が穿設された組付け板部2に2個の電線接続部5,5が一体に設けられた従来のアース端子1(図3、参照)にくらべ、各々の第1及び第2組合せ端子金具41,61は、熱容量が小さく、放熱面積も狭くできる。
【0025】
そこで、第1及び第2の組合せ端子金具41,61における各電線接続部45,65とアース電線Gの導体部分18とを、容易に溶着固定することができ、電線接続部45及び65における接触抵抗のばらつきを防止し、電気的接続の信頼性を高めることができる。
【0026】
そして、図2に示したように、前記組付け板部43,63相互を積層状態に組み合わせ、これら組付け板部43,63の2個の貫通穴47,48及び67,68を互いに一致させると共に、組付け板部43,63を互いの係合突片49,50,69,70により押さえるようにしながらそれぞれ別体に形成された一組の第1及び第2の組合せ端子金具41,61を係合合体させることにより、互いに間隔を空けて設けられた2本のアース用スタッドボルトに2本のアース電線Gをアース接続する為のアース端子31を形成することができる。
【0027】
そこで、2本のアース用スタッドボルトによりアースパネルに締結固定されたアース端子31は、該アースパネルに対する接触面積を広くでき、良好なアース接続を得ることができると共に、確実に固定される。
従って、本実施形態のアース端子31は、互いに間隔を空けて設けられた2本のアース用スタッドボルトに2本のアース電線Gをアース接続可能なアース端子でありながら、各電線接続部45,65にアース電線Gの導体部分18を溶着固定することができる。
【0028】
尚、本発明のアース端子における電線接続部、組付け板部及び組合せ端子金具等の構成は、上記実施形態の構成に限定されるものではなく、本発明の趣旨に基づいて種々の形態を採りうることは云うまでもない。
例えば、上記実施形態のアース端子31は、2本のアース用スタッドボルトに2本のアース電線をアース接続するものであり、2枚の組合せ端子金具で構成したが、3本以上のアース電線Gをアース接続するべく3枚以上の組合せ端子金具で構成することもできる。
【0029】
【発明の効果】
上述したように本発明のアース端子によれば、互いに係合合体させられる前の各組合せ端子金具は、それぞれ複数の貫通穴が穿設された組付け板部毎に1箇所の電線接続部を備えた構成であり、複数の貫通穴が穿設された組付け板部に複数の電線接続部が一体に設けられた従来のアース端子にくらべ、各組合せ端子金具は、熱容量が小さく、放熱面積も狭くできる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ground terminal, and more particularly, to a ground terminal for connecting a plurality of ground wires from a device side to a plurality of ground stud bolts provided at intervals from each other.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in a vehicle-mounted electric device or the like having a built-in computer or the like, it is necessary to provide a reliable grounding to a vehicle body in order to prevent a malfunction.
As a structure for this, a plurality of stud bolts screwed into a predetermined ground position spaced at a predetermined interval on a ground panel (vehicle panel or the like) connect a plurality of stud bolts to a plurality of ground terminals from each electronic device. In some cases, a ground wire is connected and ground connection is made at a plurality of positions.
[0003]
FIG. 3 shows a schematic configuration of a conventional ground terminal for performing such ground connection at a plurality of positions.
The ground terminal 1 shown here is a ground terminal for connecting two ground wires G from the electronic device side to two ground stud bolts 3 provided at an interval from each other. An assembly portion 2 having two through holes 6 and 6 through which the stud bolt 3 is inserted and two wire connection portions 5 and 5 for crimping and connecting the ends of the ground wire G are integrally provided. Have been.
[0004]
Therefore, first, as shown in FIG. 3A, the ground terminal 1 is connected to two wire connecting portions 5 appropriately extended at one end edge of a substantially rectangular mounting portion 2 by connecting the ends of the ground wire G to each other. The part is crimped. The wire connecting portion 5 includes a pair of core wire caulking pieces 5a, 5a and a pair of wire covering caulking pieces 5b, 5b, and an end of each ground wire G is crimped by a caulking device (not shown). .
[0005]
Next, as shown in FIG. 3B, the ground terminal 1 is fixed by tightening two ground stud bolts 3 screwed into mounting holes 7 provided at predetermined intervals on the vehicle body panel 4. You.
That is, compared with the case where a plurality of LA terminals are fastened together to one ground stud bolt, the ground terminal 1 can have a larger contact area with the vehicle body panel 4 and can obtain a good ground connection. Securely fixed.
[0006]
By the way, when the wire end is crimped to the wire connection part, if the conductor has a multi-core stranded structure, the core wire located on the outer peripheral side directly contacts the connection terminal, so it is easy to obtain conduction, but the center side Since the located core wire comes into contact with the connection terminal via the outer core wire, a difference occurs in the contact resistance between the inner core wire and the outer core wire, and the electric resistance at the wire connection portion is changed. Could be increased.
[0007]
Therefore, recently, in order to prevent variation in contact resistance at the wire connection portion, a welding terminal in which a conductor is welded at the wire connection portion has been used (for example, see Patent Document 1).
As shown in FIG. 4, the welding terminal 10 has a grounding hole (through hole) 13 which is an electrical connection portion on the front end side of the terminal board portion 11, and a pair of wire covering caulking pieces 15 on the rear end side. A pair of side walls 12, 12 are vertically provided on both sides of an intermediate portion of the terminal board portion 11, which is a welded portion, to have a U-shaped cross section.
[0008]
Then, between the side walls 12 and 12 of the terminal board portion 11 to be a welded portion, the conductor portion 18 which is obtained by peeling the insulating coating 17 of the ground wire G and exposing is set.
In this state, when the vibration horn 19 is pressed against the conductor portion 18 from above and the vibration horn 19 is ultrasonically vibrated, the respective core wires of the conductor portion 18 are locally heated due to the vibration energy generated by the ultrasonic vibration energy. Melts.
[0009]
At this time, the side walls 12, 12 prevent the cores of the conductor portion 18 pressed by the vibration horn 19 from being separated, and prevent the vibration energy of the ultrasonic wave from being difficult to transmit.
Thus, the conductor portion 18 of the ground wire G is integrally welded and fixed to the terminal board portion 11 of the welding terminal 10.
[0010]
Therefore, the welding terminal 100 can improve the reliability of the electrical connection as compared with the crimp terminal in which the conductor portion of the electric wire is crimped and fixed by crimping the conductor portion with the core wire crimping piece integrally formed on the terminal board portion. .
The welding method for welding and fixing the conductor portion 108 of the electric wire 106 to the terminal board portion 101 of the welding terminal 100 is not limited to the ultrasonic welding method having the vibration horn 110, and the conductor portion 108 may be formed by welding electrodes. Resistance welding method of welding the semiconductor chip to the terminal board part 101, laser welding, or the like can be used.
[0011]

Japanese Patent Application No. 62-140308
[Problems to be solved by the invention]
However, the ground terminal 1 in which a plurality of electric wire connection portions are integrally provided in a large-sized assembly portion 2 in which a plurality of through holes 6 are formed has a larger heat capacity than the welding terminal 10 shown in FIG. Also, since the heat radiation area is large, it is difficult for heat energy generated by the vibration horn, laser or the like to be concentrated on the wire connection part.
Therefore, even if an attempt is made to weld the conductor of the ground wire G to each wire connection portion of the ground terminal 1, the wire connection portion and the conductor portion are not easily welded, and there is a possibility that poor contact at the wire connection portion may occur.
[0013]
Therefore, an object of the present invention is to solve the above-described problems, and is a ground terminal for connecting a plurality of ground wires to a plurality of ground stud bolts provided at intervals from each other, but also to a wire connection portion.

The metal fittings are engaged so that the plurality of through-holes of the mounting plate portion of each of the combined terminal metal fittings are aligned with each other, and then are fastened and fixed by the plurality of ground stud bolts. Achieved by a ground terminal.
[0015]
According to the ground terminal having the above configuration, each of the combination terminal fittings before being combined with each other is provided with one wire connection portion for each assembly plate portion having a plurality of through holes. In addition, each of the combination terminal fittings has a smaller heat capacity and a smaller heat dissipation area than a conventional ground terminal in which a plurality of wire connection portions are integrally provided on an assembly plate portion having a plurality of through holes.
Therefore, the electric wire connection part and the conductor part of the earth electric wire in each combination terminal fitting can be easily welded.
[0016]
Then, a plurality of combined terminal fittings formed separately are engaged with each other, thereby connecting a plurality of ground wires to a plurality of ground stud bolts provided at intervals from each other. Can be formed.
That is, the ground terminal has a large contact area with the vehicle body panel and the like, and can obtain a secure ground connection, and can also enhance the reliability of the electrical connection between the wire connection portion and the ground wire.
