【発明の属する技術分野】
本発明は、基板の後端に電線を接続する圧着部を有すると共に、先端にボルト孔を穿設した固定部を有しており、該固定部が被着面にボルト固定されるアース用端子金具に関する。
【０００２】
【従来の技術】
従来より、例えば自動車等に搭載される電装部品は、接地回路を車体パネル等に接続する場合に、密着面積を大きくして導通性を確実にするためのアース用端子金具を使用している（例えば、特許文献１及び２参照。）。
【０００３】
図８に示すように、従来のアース用端子金具１は、導電性金属板からなる基板３の表面（図８中、上面）の後端に電線Ｗを電気的に接続する圧着部５を有すると共に、先端にボルト孔７を穿設した固定部９を有する所謂ＬＡ端子である。
そこで、前記アース用端子金具１は、基板３の表面に圧着部５が高く突出し、基板３の裏面（図８中、下面）が平坦な取付け面となる。
【０００４】
そして、前記アース用端子金具１は、図９に示すように、平坦な基板３の取付け面を被着面である車体パネル１１に当接させ、ボルト孔７に挿入したボルト１３を車体パネル１１の取付孔１５に螺着することで、固定部９を車体パネル１１の表面に密着固定し、良好な導通性を確保していた。
なお、前記アース用端子金具１の近傍の電線Ｗは、図示しないワイヤハーネスと伴に車体に配索された際に、バンドクリップ１７によって車体パネル１１に固定される。

【発明が解決しようとする課題】
しかしながら、上述した如き従来のアース用端子金具１は、基板３の表面に圧着部５が高く突出している為、図１０に示すように、圧着部５を設けた表面が車体パネル１１に当接する向きで固定を行なおうとしても、該圧着部５が車体パネル１１に干渉し、固定部９の全面が車体パネル１１に密着しなくなるので、導通性が低下する虞があった。
【０００７】
そして、車体パネル１１に配索後に、固定部９の取付け向きを変えようとしても、アース用端子金具１の近傍の電線Ｗは、バンドクリップ１７によって固定されているため、その反転は困難であった。
また、アース用端子金具１の固定時に、その都度表裏を判別する事は、取付作業性を低下させる。更に、アース用端子金具１の取付け向きが表裏で制約されることは、人手によらないで固定を行う自動化の障害ともなる。
【０００８】
従って、本発明の目的は上記課題を解消することに係り、被着面に対する接続信頼性及び取付作業性を向上させることができる良好なアース用端子金具を提供することである。
【０００９】
【課題を解決するための手段】
本発明の上記目的は、導電性金属板からなる基板の後端に電線を電気的に接続する圧着部を有すると共に、先端にボルト孔を穿設した固定部を有するアース用端子金具であって、
導電性の補助部材が前記固定部に取付けられることによって、前記圧着部を形成された側の固定部の取付け面が、前記圧着部より高くされることを特徴とするアース用端子金具により達成される。

上記構成のアース用端子金具によれば、圧着部を形成された側の固定部の取付け面が被着面にボルト固定されても、圧着部が被着面に干渉することは無く、固定部の全面が被着面に密着して固定されることになる。
そこで、前記固定部の表裏何れであっても被着面に取付け面を密着させて固定することが可能となり、アース接続不良が防止されるとともに、表裏の判別が不要になって、取付け作業性の向上が図れる。また、固定部の表裏何れでの取付けも可能となるので、人手によらないで固定を行う自動化も容易となる。
【００１１】
尚、好ましくは前記補助部材が、所定の厚みを有して前記固定部に重ねられる環状本体と、該固定部との間に設けられた係止手段とから成り、前記固定部に係着される。
又、好ましくは前記補助部材が、前記固定部と略同一形状に形成されて所定の厚みを有する一対の挟持板と、これら挟持板を平行に離間させた状態に連結する連結部とから成り、前記固定部に挟装される。

又、アース用端子金具２１の表裏の判別が不要になって、取付け作業性の向上が図れる。更に、固定部４１の表裏何れの取付け面４１ａ，４１ｂでの取付けも可能となるので、人手によらないで固定を行う自動化も容易となる。

尚、前記補助部材５７は、一対の挟持板５３，５３の間隙５５が、前記固定部４１の板厚より若干狭く設定されており、これら挟持板５３，５３の挟持力により固定される。又、前記補助部材５７は、板材を所定形状に打ち抜いた後に、折り曲げ成形して形成することができる。
【００２０】
即ち、本実施形態のアース用端子金具５１は、図５に示すように、補助部材５７を固定部４１に取付けることで、補助部材５７を含んだ固定部４１の高さ（厚み）Ａが、電線Ｗを圧着した圧着部２９の高さ（厚み）ａより高くなっており（Ａ＞ａ）、圧着部２９を形成された側の固定部４１の取付け面４１ａも、圧着部２９と同等或いはそれより高くなっている。

[Prior art]
2. Description of the Related Art Conventionally, an electrical component mounted on, for example, an automobile or the like has used a ground terminal fitting for increasing a contact area and ensuring conductivity when a ground circuit is connected to a vehicle body panel or the like ( For example, see Patent Documents 1 and 2.)
[0003]
As shown in FIG. 8, the conventional ground terminal fitting 1 has a crimping portion 5 for electrically connecting the electric wire W to the rear end of the surface (the upper surface in FIG. 8) of the substrate 3 made of a conductive metal plate. A so-called LA terminal having a fixing portion 9 having a bolt hole 7 formed at the tip.
Therefore, in the ground terminal fitting 1, the crimping portion 5 protrudes high on the surface of the substrate 3, and the back surface (the lower surface in FIG. 8) of the substrate 3 becomes a flat mounting surface.
[0004]
As shown in FIG. 9, the ground terminal fitting 1 has a flat mounting surface of the substrate 3 in contact with a vehicle body panel 11 as an attachment surface, and a bolt 13 inserted into the bolt hole 7 is connected to the vehicle body panel 11. The fixing portion 9 is tightly fixed to the surface of the vehicle body panel 11 by screwing into the mounting hole 15 of the above, and good conductivity is secured.
The electric wire W in the vicinity of the ground terminal fitting 1 is fixed to the vehicle body panel 11 by the band clip 17 when the electric wire W is arranged on the vehicle body together with a wire harness (not shown).

JP 2000-277192 A
[Problems to be solved by the invention]
However, in the conventional ground terminal fitting 1 as described above, since the crimping portion 5 protrudes high from the surface of the substrate 3, the surface provided with the crimping portion 5 comes into contact with the vehicle body panel 11, as shown in FIG. Even if the fixing is performed in the orientation, the crimping portion 5 interferes with the vehicle body panel 11 and the entire surface of the fixing portion 9 does not adhere to the vehicle body panel 11, so that there is a possibility that the conductivity may be reduced.
[0007]
Then, even if the mounting direction of the fixing portion 9 is changed after wiring on the vehicle body panel 11, the electric wire W in the vicinity of the ground terminal 1 is fixed by the band clip 17, so that it is difficult to invert the wire W. Was.
In addition, when the ground terminal 1 is fixed, discriminating between the front and back sides each time the fixing is performed lowers the mounting workability. Furthermore, if the mounting direction of the ground terminal fitting 1 is restricted on the front and back sides, it also becomes an obstacle to automation for fixing without manual operation.
[0008]

This is achieved by the grounding terminal fitting, wherein the mounting surface of the fixing portion on the side where the crimping portion is formed is made higher than the crimping portion by attaching a conductive auxiliary member to the fixing portion. .
[0010]
According to the grounding terminal fitting having the above configuration, even if the mounting surface of the fixing portion on the side where the crimping portion is formed is bolted to the mounting surface, the crimping portion does not interfere with the mounting surface, and the fixing portion does not interfere.

According to the above configurations, the positioning and fixing of the auxiliary member are facilitated, and the mounting workability is improved.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a ground terminal fitting according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is an exploded perspective view of a ground terminal fitting according to a first embodiment of the present invention, FIG. 2 is a perspective view showing a back surface of the substrate shown in FIG. 1, and FIG. 3 is a ground terminal fitting shown in FIG. It is a side view of the assembling state.
[0013]
As shown in FIG. 1, the ground terminal 21 according to the first embodiment includes a substrate 23 made of a conductive metal plate (for example, a copper plate) and a conductive auxiliary member 45 attached to the substrate 23. Consisting of
The substrate 23 has a crimping portion 29 for electrically connecting the electric wire W at a rear end, and a fixing portion 41 having a bolt hole 39 at a front end.
[0014]
The crimping portion 29 includes a sheath crimping portion 29a for crimping the insulating coating 31 of the electric wire W from the outside and a conductor crimping portion 29b for crimping only the conductor 33 from which the insulating coating 31 has been removed. Further, the fixing portion 41 has a substantially annular shape in which a bolt hole 39 is disposed at the center.
Therefore, the crimping portion 29 protrudes from the front surface (the upper surface in FIG. 1) of the substrate 23, and the back surface (the lower surface in FIG. 1) of the substrate 23 becomes a flat mounting surface 41b (see FIG. 2).
[0015]
The auxiliary member 45 includes an annular main body 46 having a predetermined thickness, which is superimposed on the fixing portion 41, and a locking means 47 provided between the main body and the fixing portion 41.

The locking means 47 is composed of a pair of locking projections 47a and locking recesses 47b provided at both ends in the diameter direction of the annular main body 46 and the fixing portion 41, respectively. The locking projection 47a has a claw at its tip, and the claw is locked to a locking portion in the locking recess 47b so that the auxiliary member 45 can be detachably attached to the fixing portion 41. It is designed to be fixed integrally. At this time, the tip of the locking projection 47a does not protrude toward the back surface of the substrate 3.
[0016]
That is, as shown in FIG. 3, the height (thickness) of the fixing portion 41 including the auxiliary member 45 is obtained by attaching the auxiliary member 45 to the fixing portion 41 of the substrate 23, as shown in FIG. 3. A is equal to or higher than the height (thickness) a of the crimping portion 29 to which the electric wire W is crimped (A ≧ a), and the mounting surface 41a of the fixing portion 41 on the side where the crimping portion 29 is formed is , The same as or higher than the crimping portion 29.

The entire mounting surface 41a of the fixing portion 41 of the terminal fitting 21 is fixed in close contact with the adhered surface.
[0017]
Therefore, regardless of the mounting surfaces 41a and 41b on the front and back sides of the fixing portion 41, the mounting surfaces 41a and 41b can be fixed to the surfaces to be adhered in close contact with each other, thereby preventing a poor ground connection.

And is sandwiched between the fixing portions 41.
The auxiliary member 57 has a gap 55 between the pair of holding plates 53, 53 set to be slightly smaller than the thickness of the fixing portion 41, and is fixed by the holding force of the holding plates 53, 53. The auxiliary member 57 can be formed by punching a plate material into a predetermined shape and then bending the plate material.
[0020]
That is, as shown in FIG. 5, the height (thickness) A of the fixing portion 41 including the auxiliary member 57 is increased by attaching the auxiliary member 57 to the fixing portion 41, as shown in FIG. 5. The height (thickness) a of the crimping portion 29 to which the wire W is crimped is higher (A> a), and the mounting surface 41a of the fixing portion 41 on the side where the crimping portion 29 is formed is equal to or smaller than the crimping portion 29 or It is higher than that.
[0021]
Thus, according to the grounding terminal fitting 51 of the present embodiment, even if the mounting surface 41a of the fixing portion 41 on the side where the crimping portion 29 is formed is bolted to an adhered surface such as a vehicle body panel, the crimping portion 29 is formed. Does not interfere with the adherend surface, and the entire surface of the mounting surface 41a of the fixing portion 41 of the ground terminal fitting 51 is fixed in close contact with the adherend surface.

And the ground connection failure is prevented. Furthermore, since the board 23 in the present embodiment does not require any locking means for fixing the auxiliary member 57 and does not require any special processing, a conventional ground terminal fitting can be used as it is.
[0023]
FIG. 6 is a side view of an assembled state of a ground terminal fitting according to a third embodiment of the present invention.
As shown in FIG. 6, the ground terminal fitting 61 according to the present embodiment includes a substrate 23 made of a conductive metal plate, and a conductive auxiliary member 63 attached to the substrate 23.

As shown in FIG. 7, the ground terminal fitting 71 according to the present embodiment includes a substrate 23 made of a conductive metal plate and a conductive auxiliary member 73 attached to the substrate 23.
[0027]
The auxiliary member 73 includes an annular main body 76 having a predetermined thickness, which is superimposed on the fixing portion 41 of the substrate 23, and locking means 75 provided between the fixing portion 41 and the annular member 76. It is engaged with the fixing part 41.
The locking means 75 is composed of a pair of locking holes 75a and locking claws 75b provided in the diametrical direction of the annular main body 76 and the fixing portion 41, respectively.
[0028]
Each of the locking holes 75a is formed by penetrating the auxiliary member 73 in the thickness direction, and a small hole into which the locking claw 75b is inserted from the lower surface (the surface that comes into contact with the fixing portion 41) of the auxiliary member 73. It has a hole 77 and a locking step 79 for locking the locking claw 75b on the upper surface side.
Each of the locking claws 75b is formed by cutting and raising the fixing portion 41 of the substrate 23, and has a claw portion 81 having an L-shaped cross section extending in the same circumferential direction at the tip.
[0029]
Then, the auxiliary member 73 inserts the locking claws 75b into the small holes 77 from below in FIG. 7 and rotates clockwise to lock the claw portions 81 of the locking claws 75b. It rides on the step portion 79 and is detachably attached to the fixing portion 41.
[0030]
That is, the grounding terminal fitting 71 of the present embodiment is configured such that the auxiliary member 73 is attached to the fixing portion 41 on the side where the crimping portion 29 is formed, so that the mounting surface 41a of the fixing portion 41 on the side where the crimping portion 29 is formed. Is equivalent to or higher than the crimping portion 29.
Therefore, similarly to the grounding terminal fitting 21 of the first embodiment, it is possible to fix each mounting surface on the mounting surface of the fixing portion 41 by bringing each mounting surface into close contact with the mounting surface, Poor ground connection is prevented.
[0031]
In addition, the configuration of the substrate, the crimping portion, the fixing portion, the auxiliary member, the locking means, and the like in the ground terminal fitting of the present invention is not limited to the configuration of each of the above embodiments, but is based on the gist of the present invention. Of course, various forms can be adopted.
[0032]
【The invention's effect】
As described in detail above, according to the grounding terminal fitting of the present invention, even when the mounting surface of the fixing portion on the side where the crimping portion is formed is bolted to the mounting surface, the crimping portion is attached to the mounting surface. There is no interference, and the entire surface of the fixing portion is fixed in close contact with the adhered surface.
Therefore, it is possible to fix the mounting surface so that the mounting surface is in close contact with the mounting surface regardless of whether the mounting portion is on the front or the back. Can be improved. In addition, since the fixing portion can be mounted on either the front or back, automation for fixing without manual operation becomes easy.
