本発明は、バッテリー端子用樹脂部品及びバッテリー端子ユニットに関する。   The present invention relates to a resin component for a battery terminal and a battery terminal unit.

従来、車両等に搭載されたバッテリーに立設されたバッテリーポストに取り付けるためのバッテリー端子が知られている。例えば特許文献１には、孔部にバッテリーポストを挿入した状態で締結させることにより、バッテリーポストに取り付けることができるバッテリー端子の構成が開示されている。   2.

特開２０１０−３５８３号公報JP 2010-3583 A

しかしながら、従来のバッテリー端子は、バッテリーポストに締め付けられる一点のみでバッテリーポストに対して保持されている。このため、バッテリー端子に組み付けられる部品の質量が増加すると、バッテリーポストに掛かる負荷が増大する虞がある。   However, the conventional battery terminal is held against the battery post at only one point that is fastened to the battery post. For this reason, when the mass of the parts assembled to the battery terminal increases, the load applied to the battery post may increase.

本発明は上記に鑑みてなされたものであって、バッテリー端子をバッテリーポストに組み付けた状態において、バッテリーポストに掛かる負荷を軽減できるバッテリー端子用樹脂部品及びバッテリー端子ユニットを提供することを目的とする。   The present invention has been made in view of the above, and an object of the present invention is to provide a battery terminal resin part and a battery terminal unit that can reduce a load applied to the battery post in a state where the battery terminal is assembled to the battery post. .

上記の課題を解決するため、本発明に係るバッテリー端子用樹脂部品は、バッテリーが搭載される本体側の電線と接続する接続部を有するバッテリー端子に組み付けられるバッテリー端子用樹脂部品であって、前記バッテリー端子が、前記バッテリーに立設されたバッテリーポストに取り付けられた状態で、前記バッテリー端子の前記接続部と前記バッテリーの表面との間隙に配置され、前記接続部を前記バッテリーの前記表面に支持する支持部材を備えることを特徴とする。   In order to solve the above problems, a resin component for a battery terminal according to the present invention is a resin component for a battery terminal that is assembled to a battery terminal having a connection portion connected to an electric wire on a main body side on which a battery is mounted, In a state where the battery terminal is attached to a battery post erected on the battery, the battery terminal is disposed in a gap between the connection portion of the battery terminal and the surface of the battery, and the connection portion is supported on the surface of the battery. It is characterized by comprising a supporting member.

また、上記のバッテリー端子用樹脂部品において、前記支持部材が振動吸収材であることが好ましい。   In the battery terminal resin component described above, it is preferable that the support member is a vibration absorbing material.

同様に、上記の課題を解決するため、本発明に係るバッテリー端子ユニットは、上記のバッテリー端子用樹脂部品と、前記バッテリー端子用樹脂部品が組み付けられるバッテリー端子と、を備えることを特徴とする。   Similarly, in order to solve the above-described problems, a battery terminal unit according to the present invention includes the battery terminal resin component and a battery terminal to which the battery terminal resin component is assembled.

本発明に係るバッテリー端子用樹脂部品及びバッテリー端子ユニットは、支持部材によって接続部を支持することができるので、接続部に付加される荷重がバッテリー端子を介してバッテリーポストに伝達されるのを抑制でき、この結果、バッテリー端子をバッテリーポストに組み付けた状態において、バッテリーポストに掛かる負荷を軽減できるという効果を奏する。   Since the resin part for battery terminals and the battery terminal unit according to the present invention can support the connection part by the support member, the load applied to the connection part is prevented from being transmitted to the battery post via the battery terminal. As a result, it is possible to reduce the load applied to the battery post in a state where the battery terminal is assembled to the battery post.

In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and the description thereof will not be repeated.

まず図１〜４を参照して、本発明の一実施形態に係るバッテリー端子ユニットの構成を説明する。図１は、本発明の一実施形態に係るバッテリー端子用樹脂部品、及びこの樹脂部品が組み付けられるバッテリー端子（すなわち本発明の一実施形態に係るバッテリー端子ユニット）と、バッテリー端子ユニットが取り付けられるバッテリーポストとを示す分解斜視図であり、図２は、図１中のバッテリー端子用樹脂部品をバッテリー端子に組み付けた状態のバッテリー端子ユニットを示す斜視図であり、図３は、本実施形態に係るバッテリー端子ユニットをバッテリーポストに取り付けた状態を示す斜視図であり、図４は、本実施形態に係るバッテリー端子ユニットをバッテリーポストに取り付けた状態を示す側面図である。なお、以下の説明では、図１において上下方向に図示される軸線Ｃの延在方向を「軸方向」と表す。また、軸線Ｃまわりの方向を「周方向」と表す。   First, with reference to FIGS. 1-4, the structure of the battery terminal unit which concerns on one Embodiment of this invention is demonstrated. 1 shows a resin component for a battery terminal according to an embodiment of the present invention, a battery terminal to which the resin component is assembled (that is, a battery terminal unit according to an embodiment of the present invention), and a battery to which the battery terminal unit is attached. 2 is an exploded perspective view showing the post, FIG. 2 is a perspective view showing the battery terminal unit in a state where the battery terminal resin component in FIG. 1 is assembled to the battery terminal, and FIG. 3 according to the present embodiment. FIG. 4 is a perspective view showing a state in which the battery terminal unit is attached to the battery post, and FIG. 4 is a side view showing a state in which the battery terminal unit according to the present embodiment is attached to the battery post. In the following description, the extending direction of the axis C illustrated in the vertical direction in FIG. Further, the direction around the axis C is represented as “circumferential direction”.

本実施形態に係るバッテリー端子ユニット１０は、図３，４に示すように、車両等に搭載されるバッテリー４に立設されたバッテリーポスト３に取り付けられるものであり、バッテリー端子用樹脂部品１（以降「樹脂部品１」とも表記する）と、バッテリー端子２とを備える。樹脂部品１は、バッテリー端子２に組み付けられる。バッテリー端子２は、バッテリーポスト３に取り付けることにより、バッテリー４と、このバッテリー４が搭載される車両等の本体側の電線（図示せず）とを電気的に接続するための部品である。バッテリー端子ユニット１０は、樹脂部品１がバッテリー端子２に一体的に組み付けられた状態で、バッテリーポスト３に取り付けられる。なお、上述した「軸方向」とは、バッテリーポスト３の軸方向であり、バッテリーポスト３がバッテリー４に立設された方向である。一般に、バッテリーポスト３は、略円柱形状であり、さらに、バッテリー４との接続部である基部３１側から軸方向に沿って先端部３２側に進むにつれて、外周側面３３の径が小さくなるようテーパが付けられている。   The battery terminal unit 10 according to the present embodiment is attached to a battery post 3 erected on a battery 4 mounted on a vehicle or the like, as shown in FIGS. Hereinafter, it is also referred to as “resin component 1”) and a battery terminal 2. The resin component 1 is assembled to the battery terminal 2. The battery terminal 2 is a component for electrically connecting the battery 4 and an electric wire (not shown) on the main body side of a vehicle or the like on which the battery 4 is mounted by being attached to the battery post 3. The battery terminal unit 10 is attached to the battery post 3 in a state where the resin component 1 is integrally assembled to the battery terminal 2. The “axial direction” described above is the axial direction of the battery post 3 and is the direction in which the battery post 3 is erected on the battery 4. In general, the battery post 3 has a substantially cylindrical shape, and further tapers so that the diameter of the outer peripheral side surface 33 becomes smaller as it proceeds from the base 31 side, which is a connection portion with the battery 4, to the tip end 32 side along the axial direction. Is attached.

図１に示すように、バッテリー端子２は、軸方向に重畳して配置される一対の環状部２１ａ，２１ｂを有する。一対の環状部２１ａ，２１ｂは、バッテリー端子２をバッテリーポスト３に取り付けた状態では、一方の環状部２１ａがバッテリーポスト３の先端部３２側に位置し、他方の環状部２１ｂが基部３１側に位置するよう配置されている。環状部２１ａ，２１ｂには、バッテリーポスト３を内側に挿入するポスト挿入孔２２が穿設されている。環状部２１ａ，２１ｂは、ポスト挿入孔２２の周方向の一箇所を分断した締付け間隙２３により開放されており、この締付け間隙２３を挟んで周方向にて対向する一対の連結部２４ａ，２４ｂにより連結されている。また、環状部２１ａ，２１ｂには、この連結部２４ａ，２４ｂの周方向の反対側の位置にて接合版２５ａ，２５ｂ同士が軸方向に重ね合わせて連結されている。   As shown in FIG. 1, the battery terminal 2 includes a pair of annular portions 21 a and 21 b that are arranged so as to overlap in the axial direction. When the battery terminal 2 is attached to the battery post 3, the pair of annular portions 21 a and 21 b are positioned so that one annular portion 21 a is positioned on the tip 32 side of the battery post 3 and the other annular portion 21 b is on the base 31 side. It is arranged to be located. A post insertion hole 22 for inserting the battery post 3 into the inside is formed in the annular portions 21a and 21b. The annular portions 21a and 21b are opened by a tightening gap 23 obtained by dividing one place in the circumferential direction of the post insertion hole 22, and a pair of connecting portions 24a and 24b opposed in the circumferential direction across the tightening gap 23. It is connected. Further, the joining plates 25a and 25b are connected to the annular portions 21a and 21b so as to overlap each other in the axial direction at a position opposite to the circumferential direction of the connecting portions 24a and 24b.

接合板２５ａ，２５ｂは、バッテリー端子２をバッテリーポスト３に取り付けた状態では、一方の接合板２５ａがバッテリーポスト３の基部３１側に位置し、他方の接合板２５ｂが先端部３２側に位置するよう配置されている。基部３１側の接合板２５ａには端子固定ボルト２６が立設されている。端子固定ボルト２６は、他方の接合板２５ｂを貫通して軸方向と略平行な方向に起立して設置されている。この端子固定ボルト２６には、本体側の電線（図示せず）が接続固定される。本実施形態では、これらの接合板２５ａ，２５ｂ及び端子固定ボルト２６が、「バッテリー４が搭載される本体側の電線と接続する接続部４１」として機能する。   When the battery terminal 2 is attached to the battery post 3, the joining plates 25 a and 25 b are located on the base 31 side of the battery post 3 and the other joining plate 25 b is located on the distal end portion 32 side. It is arranged as follows. A terminal fixing bolt 26 is erected on the joining plate 25a on the base 31 side. The terminal fixing bolt 26 is installed upright in a direction substantially parallel to the axial direction through the other joining plate 25b. An electric wire (not shown) on the main body side is connected and fixed to the terminal fixing bolt 26. In the present embodiment, these joining plates 25a and 25b and the terminal fixing bolts 26 function as the “connecting portion 41 that is connected to the electric wire on the main body side on which the battery 4 is mounted”.

一対の連結部２４ａ，２４ｂには、締付け間隙２３を横断する締付けボルト２７が貫通されている。連結部２４ａ，２４ｂを貫通して設置される締付けボルト２７は、その先端に羅合されているナット２８と協働して、連結部２４ａ，２４ｂを接近方向に締め付けることができる。これにより、環状部２１ａ，２１ｂのポスト挿入孔２２は縮径することになる。   A tightening bolt 27 crossing the tightening gap 23 is passed through the pair of connecting portions 24a and 24b. The tightening bolt 27 installed through the connecting portions 24a and 24b can tighten the connecting portions 24a and 24b in the approaching direction in cooperation with the nut 28 fitted at the tip thereof. As a result, the post insertion holes 22 of the annular portions 21a and 21b are reduced in diameter.

ポスト挿入孔２２には、穴縁部を起立状態に折り曲げた（所謂、鍔出しした）鍔状の接触部２９が形成されている。接触部２９は、一対の環状部２１ａ，２１ｂのそれぞれにおいて、共にバッテリーポスト３の基部３１側（図１の下方向）に折り曲げられて形成されている。接触部２９は、バッテリーポスト３のテーパと一致するテーパ形状で内周面が形成されている。従って、ポスト挿入孔２２にバッテリーポスト３が挿入されたバッテリー端子２は、ナット２８を締め付け、締付け間隙２３を接近させることで、接触部２９をバッテリーポスト３の外周側面３３に密接させた状態で取り付けることができる。   The post insertion hole 22 is formed with a hook-shaped contact portion 29 in which the hole edge portion is bent in an upright state (so-called protruding). The contact portion 29 is formed by bending the battery post 3 toward the base portion 31 (downward in FIG. 1) in each of the pair of annular portions 21a and 21b. The contact portion 29 has a tapered shape that matches the taper of the battery post 3 and has an inner peripheral surface. Therefore, in the battery terminal 2 in which the battery post 3 is inserted into the post insertion hole 22, the contact portion 29 is brought into close contact with the outer peripheral side surface 33 of the battery post 3 by tightening the nut 28 and bringing the tightening gap 23 closer. Can be attached.

ここで、図１に示すように、一般に、バッテリーポスト３の基部３１は、外周側面３３より径が大きく、径方向外側に突出する形状をとるので、外周側面３３の周囲に沿って円環状の対向面３１ａを有する。対向面３１ａは、先端部３２の端面と略平行に配置される。バッテリー端子２は、ポスト挿入孔２２がバッテリーポスト３に挿入され、底面（より詳細にはバッテリー端子２に組みつけられた樹脂部品の底面）がバッテリーポスト３の基部３１の対向面３１ａに突き当てられた状態で、バッテリーポスト３に取り付けられる（図４参照）。   Here, as shown in FIG. 1, the base 31 of the battery post 3 is generally larger in diameter than the outer peripheral side surface 33 and has a shape projecting radially outward, and therefore has an annular shape along the periphery of the outer peripheral side surface 33. It has a facing surface 31a. The facing surface 31 a is disposed substantially parallel to the end surface of the tip end portion 32. In the battery terminal 2, the post insertion hole 22 is inserted into the battery post 3, and the bottom surface (more specifically, the bottom surface of the resin component assembled to the battery terminal 2) abuts the facing surface 31 a of the base 31 of the battery post 3. In this state, it is attached to the battery post 3 (see FIG. 4).

樹脂部品１は、このようなバッテリー端子２に一体的に組み付けられる。樹脂部品１は、バッテリー端子２に防食機能を持たせる防食カバーとして、バッテリー端子２とバッテリー４との間に介在する部材である。このため、樹脂部品１は、バッテリー液に対しての耐食性を持たせるために（防食機能を持たせるために）合成樹脂材料を用いて成形されている。   The resin component 1 is integrally assembled to such a battery terminal 2. The resin component 1 is a member interposed between the battery terminal 2 and the battery 4 as an anticorrosion cover that gives the battery terminal 2 an anticorrosion function. For this reason, the resin component 1 is molded using a synthetic resin material in order to provide corrosion resistance to the battery liquid (to provide an anticorrosion function).

図１に示すように、樹脂部品１は、底面カバー１１と、蓋部１２と、ヒンジ１３と、ロック部１４と、支持部材１５とを備える。樹脂部品１は、図２に示すように、底面カバー１１と蓋部１２とでバッテリー端子２を挟み込み、この挟み込み状態をロック部１４によって維持することによりバッテリー端子２に対して一体的に組み付けられるよう構成されている。樹脂部品１は、底面カバー１１、蓋部１２、ヒンジ１３、ロック部１４が上記の合成樹脂材料で一体成形されている。また、支持部材１５は、ゴムやシリコンなどの振動吸収材で形成されている。   As shown in FIG. 1, the resin component 1 includes a bottom cover 11, a lid portion 12, a hinge 13, a lock portion 14, and a support member 15. As shown in FIG. 2, the resin component 1 is assembled integrally with the battery terminal 2 by sandwiching the battery terminal 2 between the bottom cover 11 and the lid portion 12 and maintaining the sandwiched state by the lock portion 14. It is configured as follows. In the resin component 1, the bottom cover 11, the lid portion 12, the hinge 13, and the lock portion 14 are integrally formed of the above synthetic resin material. The support member 15 is formed of a vibration absorbing material such as rubber or silicon.

底面カバー１１は、図１に示すように、バッテリー端子２とバッテリーポスト３の対向面３１ａとの間に介在し、バッテリー端子２の底面（環状部２１ｂ及び接合板２５ａ側の面）を被覆する板状部材である。底面カバー１１には、バッテリーポスト３に対する挿入孔１７が貫通形成されている。また、底面カバー１１において、バッテリー端子２と対向する面には、仮ロック部１６が設けられている。仮ロック部１６は、バッテリー端子２を底面カバー１１に仮止めするための部材であり、本実施形態では係止突起の構成を例示している。仮ロック部１６は、バッテリー端子２を底面カバー１１に組み付けた状態で、バッテリー端子２の環状部２１ａ、２１ｂの側面の開口４２に係止することができ、また、接合板２５ａ，２５ｂの間隙に係止することができる。   As shown in FIG. 1, the bottom cover 11 is interposed between the battery terminal 2 and the facing surface 31a of the battery post 3, and covers the bottom surface of the battery terminal 2 (the surface on the annular portion 21b and the joining plate 25a side). It is a plate-like member. An insertion hole 17 for the battery post 3 is formed through the bottom cover 11. A temporary lock portion 16 is provided on the bottom cover 11 on the surface facing the battery terminal 2. The temporary lock portion 16 is a member for temporarily fixing the battery terminal 2 to the bottom surface cover 11, and in this embodiment, the configuration of the locking protrusion is illustrated. The temporary lock portion 16 can be locked to the openings 42 on the side surfaces of the annular portions 21a and 21b of the battery terminal 2 in a state where the battery terminal 2 is assembled to the bottom cover 11, and the gap between the joining plates 25a and 25b. Can be locked to.

蓋部１２は、図２に示すように、底面カバー１１と軸方向の反対側からバッテリー端子２を覆う板状部材である。本実施形態では、蓋部１２は、略短冊形状であり略ブリッジ形状の板状部材として例示されている。蓋部１２は、バッテリー端子２の底面と反対側の面（環状部２１ａ及び接合板２５ｂ側の面）と当接するよう配置されている。蓋部１２の中央部分には、バッテリー端子２のポスト挿入孔２２に対する逃がしとなる挿入孔逃がし部分１２ａが形成されている。蓋部１２は、バッテリー端子２の締付けボルト２７の軸方向と並行な方向に延在する。   As shown in FIG. 2, the lid 12 is a plate-like member that covers the battery terminal 2 from the side opposite to the bottom cover 11 in the axial direction. In the present embodiment, the lid portion 12 has a substantially strip shape and is illustrated as a substantially bridge-shaped plate member. The lid portion 12 is disposed so as to contact the surface opposite to the bottom surface of the battery terminal 2 (the surface on the annular portion 21a and the joining plate 25b side). An insertion hole escape portion 12 a that allows the battery terminal 2 to escape from the post insertion hole 22 is formed in the center portion of the lid portion 12. The lid portion 12 extends in a direction parallel to the axial direction of the fastening bolt 27 of the battery terminal 2.

ヒンジ１３は、図１に示すように、底面カバー１１と蓋部１２とを連結する部分である。ヒンジ１３は、樹脂部品１の他の部分と比較して薄肉状に形成されており、自在に変形可能である。このため、樹脂部品１では、ヒンジ１３との接続位置を中心として、底面カバー１１に対する蓋部１２の傾斜角度を変更させることができる。   As shown in FIG. 1, the hinge 13 is a part that connects the bottom cover 11 and the lid 12. The hinge 13 is formed thinner than the other parts of the resin component 1 and can be freely deformed. For this reason, in the resin component 1, the inclination angle of the lid portion 12 with respect to the bottom surface cover 11 can be changed around the connection position with the hinge 13.

ロック部１４は、蓋部１２を底面カバー１１に固定する部分である。ロック部１４は、蓋部１２と底面カバー１１の両方に形成される。ロック部１４は、例えば、係止突起と、この係止突起に引っ掛かる係止枠部とで構成されている。   The lock portion 14 is a portion that fixes the lid portion 12 to the bottom surface cover 11. The lock portion 14 is formed on both the lid portion 12 and the bottom cover 11. The lock part 14 is comprised by the latching protrusion and the latching frame part hooked on this latching protrusion, for example.

支持部材１５は、バッテリーポスト３への取り付け時にバッテリーポスト３の対向面３１ａと対向する、底面カバー１１の底面に形成される。支持部材１５は、図３，４に示すように、樹脂部品１及びバッテリー端子２をバッテリーポスト３に組み付けた状態において、少なくとも、バッテリー端子２の接続部４１とバッテリー４の表面４ａとの間の領域に配置され、接続部４１を支持することができるよう構成されている。言い換えると、支持部材１５は、バッテリー端子２の接続部４１とバッテリー４の表面４ａとの間隙であり、かつ、軸方向から視た場合に、少なくとも接続部４１の端子固定ボルト２６と重畳する領域に配置され、好ましくは、接続部４１全体と重畳する領域に配置される。支持部材１５は、上述のようにゴムやシリコンなどの振動吸収材で形成される。支持部材１５は、樹脂部品１の他の部分と一体成形するか、または粘着材などで固定するなどの手法によって、底面カバー１１に固着される。   The support member 15 is formed on the bottom surface of the bottom cover 11 that faces the facing surface 31 a of the battery post 3 when attached to the battery post 3. As shown in FIGS. 3 and 4, the support member 15 is at least between the connection portion 41 of the battery terminal 2 and the surface 4 a of the battery 4 in a state where the resin component 1 and the battery terminal 2 are assembled to the battery post 3. It arrange | positions in an area | region and is comprised so that the connection part 41 can be supported. In other words, the support member 15 is a gap between the connection portion 41 of the battery terminal 2 and the surface 4a of the battery 4, and at least overlaps with the terminal fixing bolt 26 of the connection portion 41 when viewed from the axial direction. Preferably, it arrange | positions in the area | region which overlaps with the connection part 41 whole. The support member 15 is formed of a vibration absorbing material such as rubber or silicon as described above. The support member 15 is fixed to the bottom cover 11 by a method such as being integrally formed with other portions of the resin component 1 or being fixed with an adhesive material or the like.

次に、樹脂部品１のバッテリー端子２への組み付け、及び、樹脂部品１を組み付けたバッテリー端子２、すなわちバッテリー端子ユニット１０のバッテリーポスト３への取り付けの手順について説明する。   Next, a procedure for assembling the resin component 1 to the battery terminal 2 and attaching the battery terminal 2 to which the resin component 1 is assembled, that is, the battery terminal unit 10 to the battery post 3 will be described.

まず、バッテリー端子２が、樹脂部品１の底面カバー１１上に組み付けられ、仮ロック部１６によって、バッテリー端子２が底面カバー１１上に仮止めされる。次に、蓋部１２が、底面カバー１１と軸方向反対側からバッテリー端子２を覆う位置まで倒し込まれる。そして、ロック部１４が嵌合されて、蓋部１２が底面カバー１１に固定される。これにより、図２に示すように、樹脂部品１とバッテリー端子２とが本嵌合され、樹脂部品１がバッテリー端子２に組み付けられ、バッテリー端子ユニット１０が一体的に構成された状態となる。   First, the battery terminal 2 is assembled on the bottom cover 11 of the resin component 1, and the battery terminal 2 is temporarily fixed on the bottom cover 11 by the temporary lock portion 16. Next, the lid 12 is pushed down to a position covering the battery terminal 2 from the side opposite to the bottom cover 11 in the axial direction. Then, the lock portion 14 is fitted and the lid portion 12 is fixed to the bottom surface cover 11. Thereby, as shown in FIG. 2, the resin component 1 and the battery terminal 2 are finally fitted, the resin component 1 is assembled to the battery terminal 2, and the battery terminal unit 10 is integrally formed.

次に、樹脂部品１を組み付けたバッテリー端子２、すなわちバッテリー端子ユニット１０のポスト挿入孔２２にバッテリーポスト３が挿入され、図４に示すように、樹脂部品１の底面カバー１１の底面がバッテリーポスト３の基部３１の対向面３１ａに突き当てられる。このとき、樹脂部品１の底面カバー１１の底面に設けられる支持部材１５も、図３，４に示すように、バッテリーポスト３が設置されるバッテリー４の表面４ａに突き当てられた状態となる。この状態において、バッテリー端子２の締付けボルト２７とナット２８を締め付けることで、バッテリー端子ユニット１０がバッテリーポスト３に取り付けられる。従って、バッテリー端子ユニット１０は、樹脂部品１の底面カバー１１によってバッテリーポスト３の対向面３１ａに支持されると共に、樹脂部品１の支持部材１５によってバッテリー４の表面４ａにも支持される、所謂二点支持の状態でバッテリーポスト３に取り付けられることとなる。支持部材１５は、上述のようにバッテリー端子２の接続部４１と、バッテリー４の表面４ａとの間に配置される。接続部４１は、車体内の他の装置と接続され、これにより外部から荷重を受ける場合が多いが、支持部材１５は、この接続部４１をバッテリー４の表面４ａに支持することができる。   Next, the battery post 3 is inserted into the battery terminal 2 to which the resin component 1 is assembled, that is, the post insertion hole 22 of the battery terminal unit 10, and the bottom surface of the bottom cover 11 of the resin component 1 is the battery post as shown in FIG. 3 is abutted against the facing surface 31a of the base 31 of the third. At this time, the support member 15 provided on the bottom surface of the bottom surface cover 11 of the resin component 1 is also in contact with the surface 4a of the battery 4 on which the battery post 3 is installed, as shown in FIGS. In this state, the battery terminal unit 10 is attached to the battery post 3 by tightening the tightening bolt 27 and the nut 28 of the battery terminal 2. Therefore, the battery terminal unit 10 is supported on the opposite surface 31a of the battery post 3 by the bottom cover 11 of the resin component 1 and also supported by the surface 4a of the battery 4 by the support member 15 of the resin component 1. It will be attached to the battery post 3 in a state of point support. The support member 15 is disposed between the connection portion 41 of the battery terminal 2 and the surface 4a of the battery 4 as described above. The connection portion 41 is connected to other devices in the vehicle body and thus receives a load from the outside in many cases. However, the support member 15 can support the connection portion 41 on the surface 4 a of the battery 4.

次に、本実施形態に係るバッテリー端子用樹脂部品１及びバッテリー端子ユニット１０の効果を説明する。   Next, effects of the battery terminal resin part 1 and the battery terminal unit 10 according to the present embodiment will be described.

本実施形態のバッテリー端子ユニット１０は、バッテリー端子用樹脂部品１と、バッテリー端子２とを備える。バッテリー端子用樹脂部品１は、バッテリー４が搭載される本体側の電線と接続する接続部４１を有するバッテリー端子２に組み付けられる。バッテリー端子用樹脂部品１は、バッテリー端子２が、バッテリー４に立設されたバッテリーポスト３に取り付けられた状態で、バッテリー端子２の接続部４１とバッテリー４の表面４ａとの間隙に配置され、接続部４１をバッテリー４の表面４ａに支持する支持部材１５を備える。   The battery terminal unit 10 of this embodiment includes a battery terminal resin part 1 and a battery terminal 2. The battery terminal resin component 1 is assembled to the battery terminal 2 having a connection portion 41 connected to the electric wire on the main body side on which the battery 4 is mounted. The battery terminal resin component 1 is disposed in the gap between the connection portion 41 of the battery terminal 2 and the surface 4a of the battery 4 in a state where the battery terminal 2 is attached to the battery post 3 erected on the battery 4. A support member 15 that supports the connection portion 41 on the surface 4 a of the battery 4 is provided.

この構成により、接続部４１に接続される本体側の部品の質量が増加し、振動等の影響によって、接続部４１に付加される荷重が増加する状況においても、図４に示すように、支持部材１５によって接続部４１をバッテリー４の表面４ａに支持することができるので、接続部４１に付加される荷重がバッテリー端子２を介してバッテリーポスト３に伝達されるのを抑制できる。これにより、バッテリーポスト３が受ける曲げモーメントを低減させることが可能となり、この結果、本実施形態のバッテリー端子用樹脂部品１及びバッテリー端子ユニット１０は、バッテリー端子２をバッテリーポスト３に組み付けた状態において、バッテリーポスト３に掛かる負荷を軽減できる。   As shown in FIG. 4, this configuration also increases the mass of the component on the main body side connected to the connection portion 41 and increases the load applied to the connection portion 41 due to the influence of vibration or the like. Since the connection portion 41 can be supported on the surface 4 a of the battery 4 by the member 15, it is possible to suppress the load applied to the connection portion 41 from being transmitted to the battery post 3 via the battery terminal 2. This makes it possible to reduce the bending moment that the battery post 3 receives. As a result, the battery terminal resin component 1 and the battery terminal unit 10 of the present embodiment are in a state where the battery terminal 2 is assembled to the battery post 3. The load on the battery post 3 can be reduced.

また、本実施形態のバッテリー端子用樹脂部品１及びバッテリー端子ユニット１０において、支持部材１５が振動吸収材であるため、接続部４１に付加される荷重を支持部材１５で吸収することが可能となり、バッテリー端子２からバッテリーポスト３に伝達される荷重をさらに抑制できるので、バッテリーポスト３に掛かる負荷をより一層軽減できる。   Further, in the battery terminal resin part 1 and the battery terminal unit 10 of the present embodiment, since the support member 15 is a vibration absorber, the load applied to the connection portion 41 can be absorbed by the support member 15. Since the load transmitted from the battery terminal 2 to the battery post 3 can be further suppressed, the load applied to the battery post 3 can be further reduced.

以上、本発明の実施形態を説明したが、上記実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。上記実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行なうことができる。上記実施形態及びその変形は、発明の範囲や要旨に含まれると同様に、特許請求の範囲に記載された発明とその均等の範囲に含まれるものである。   As mentioned above, although embodiment of this invention was described, the said embodiment was shown as an example and is not intending limiting the range of invention. The above embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. The above-described embodiments and modifications thereof are included in the invention described in the claims and the equivalents thereof, as long as they are included in the scope and gist of the invention.

上記実施形態では、支持部材１５が振動吸収材である構成を例示したが、支持部材１５は接続部４１を支持することができれば他の材料を用いてもよい。例えば、支持部材１５を、バッテリー端子用樹脂部品１の他の要素と同様に、合成樹脂材料で一体成形してもよい。   In the above-described embodiment, the configuration in which the support member 15 is a vibration absorbing material has been exemplified. However, the support member 15 may use other materials as long as it can support the connection portion 41. For example, the support member 15 may be integrally formed of a synthetic resin material in the same manner as the other elements of the battery terminal resin part 1.
