Description
本発明は、電動工具及び電気機器に使用する電池パックに関するものである。 The present invention relates to a battery pack used for electric tools and electric devices.
従来から作業性を良くするために、電池パックを動力として動く電動工具がある。この電池パックは、開口部が形成されたハウジングを有し、ハウジング内には、セル群、基板、及び第１端子が収容されている。端子は、開口部近傍に、電動工具の本体部又は充電器の第２端子と嵌合可能に設けられている。基板は、端子から離間した位置に配置され、リード線により端子と接続されている。 Conventionally, in order to improve workability, there is an electric tool that uses a battery pack as power. This battery pack has a housing in which an opening is formed, and a cell group, a substrate, and a first terminal are accommodated in the housing. The terminal is provided in the vicinity of the opening so as to be fitted to the main body of the electric tool or the second terminal of the charger. The substrate is disposed at a position separated from the terminal, and is connected to the terminal by a lead wire.
しかし、従来の電池パックは図８のように一点を中心にラッチが回動動作する構造となっているが、この場合、操作部のスライド方向先端を操作しなければ、ラッチを操作できず電動工具との係止を解除できないため操作性の悪さが問題となっている。 However, the conventional battery pack has a structure in which the latch pivots around one point as shown in FIG. 8, but in this case, the latch cannot be operated unless the sliding end of the operation portion is operated. Poor operability is a problem because the locking with the tool cannot be released.
そこで、図９のようにラッチが電池ケースに設けられた溝を摺動し、ラッチが平行にスライド動作することで、操作部のどの部分を操作しても、ラッチを操作できるようになり操作性が向上した電池パックが使用されるようになった。 Therefore, as shown in Fig. 9, the latch slides in the groove provided in the battery case, and the latch slides in parallel, so that the latch can be operated regardless of which part of the operation unit is operated. Battery packs with improved performance have been used.
しかし、このような構成ではラッチと溝には摺動をするための隙間が設けられているため、操作部を操作した時にラッチが傾く状態となる。ラッチの傾きが最大となった時に、ラッチと電池ケースはラッチの両端側の左右二箇所で接触した状態となり（接触点３６Ａ、３６Ｂ）、ラッチが突っかかりラッチのスライド方向の摺動性が悪いという課題があった。 However, in such a configuration, a gap for sliding is provided in the latch and the groove, so that the latch is inclined when the operation unit is operated. When the inclination of the latch becomes maximum, the latch and the battery case are in contact with each other at two left and right sides of the latch (contact points 36A and 36B), and the latch hits and the sliding property of the latch in the sliding direction is poor. There was a problem.
そこで本発明は、上記従来の欠点を解消し、ラッチのスライド方向の摺動性が向上した電池パックを提供することを目的とする。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a battery pack that eliminates the above-described conventional drawbacks and has improved slidability in the sliding direction of the latch.

The battery pack 10 will be described in detail with reference to FIGS. 3 and 4. The battery pack 10 includes a housing 11, a cell group 12, a substrate 13, a plurality of second terminals 14, and a cover 15. The housing 11 includes an upper housing 16 and a lower housing 17 and accommodates the cell group 12, the substrate 13, the plurality of second terminals 14, and the cover 15. The upper housing 16 mainly includes a terminal insertion portion 16A and an opening defining portion 16B. A substantially rectangular opening 16c is defined by the terminal insertion portion 16A and the opening defining portion 16B. The opening 16c functions as an insertion portion for inserting a plate-shaped protection member that protects a terminal of a charger (not shown) when the battery pack 10 is connected to a charger (not shown) for charging. The terminal insertion portion 16A is formed with a plurality of slots 16d that open toward the rear.
図２に示すように、セル群１２は、複数のセルを備え、各セルは、ニッケル水素電池又はリチウムイオン電池等からなり、複数回充放電可能な電池である。基板１３は、セル群１２上に設けられ、セル群１２と電気的に接続されている。基板１３には、開口部１６ｃの長手方向に沿って延びる端子配置部１３Ａが規定されている。また、基板１３の後方側の端縁１３Ｂは、上側ハウジング１６の開口規定部１６Ｂの前方側の端縁１６Ｅ（図３）に対向するように配置されている。 As shown in FIG. 2, the cell group 12 includes a plurality of cells, and each cell includes a nickel-metal hydride battery or a lithium ion battery, and is a battery that can be charged and discharged a plurality of times. The substrate 13 is provided on the cell group 12 and is electrically connected to the cell group 12. The board 13 defines a terminal arrangement portion 13A extending along the longitudinal direction of the opening 16c. Further, the rear edge 13 </ b> B of the substrate 13 is disposed so as to face the front edge 16 </ b> E (FIG. 3) of the opening defining portion 16 </ b> B of the upper housing 16.
複数の第２端子１４は、基板１３の端子配置部１３Ａに、開口部１６ｃの長手方向に沿って並ぶように配置され、基板１３と電気的に接続されている。複数の第２端子１４は、電池パック１０が一体に組まれた状態で、それぞれスロット１６ｄ内に位置する。複数の第２端子１４は、それぞれ平板をＵ字形状に曲げ、開口端部を塞ぐように平板の端部付近を接触させた形状をなしている。そして、電池パック１０がハンドル３の先端に取り付けられるときは、第１端子３Ｂは、後方側からスロット１６ｄに挿入され、第２端子１４にその開口端部を押し広げるように嵌合圧入されて、第１端子３Ｂと第２端子１４とは嵌合する。 The plurality of second terminals 14 are arranged on the terminal arrangement portion 13 </ b> A of the substrate 13 so as to be arranged along the longitudinal direction of the opening 16 c, and are electrically connected to the substrate 13.

Each of the plurality of second terminals 14 has a shape in which the flat plate is bent into a U shape and the vicinity of the end of the flat plate is brought into contact so as to close the open end. When the battery pack 10 is attached to the front end of the handle 3, the first terminal 3B is inserted into the slot 16d from the rear side, and is fitted and press-fitted into the second terminal 14 so as to expand the opening end. The first terminal 3B and the second terminal 14 are fitted.
つぎに、電池パックのラッチ部分について図３に基づいて説明する。図３は、操作部（ラッチ）３１が、上側ハウジング１６の短手方向と平行にスライド摺動する構成を示しており、下側ハウジング１７のケース内の上面に収容されたラッチ３１が弾性体３２によってハウジング１１の外側方向に付勢されている。ラッチが図４の紙面と垂直上方向に動くことを防ぐため、締付ねじ３４によって、紙面と垂直下方向に保持している。さらに、ハウジング１１にはラッチ３１をガイドするリブ状の溝３５が形成され、溝３５に沿ってラッチ３１が移動することによって、ラッチに形成されたフック状の係合部３０が連動して摺動し、工具本体１側に設けられた受部３３と係合することで電池パック１０と工具本体1とを固定する。 Next, the latch portion of the battery pack will be described with reference to FIG. FIG. 3 shows a configuration in which the operating portion (latch) 31 slides and slides in parallel with the short side direction of the upper housing 16, and the latch 31 housed on the upper surface in the case of the lower housing 17 is an elastic body. 32 is biased toward the outside of the housing 11. In order to prevent the latch from moving vertically upward with respect to the paper surface of FIG. 4, the latch is held in a downward direction perpendicular to the paper surface by a tightening screw 34. Further, a rib-shaped groove 35 for guiding the latch 31 is formed in the housing 11, and the latch 31 moves along the groove 35, so that the hook-shaped engaging portion 30 formed in the latch is interlocked and slid. The battery pack 10 and the tool body 1 are fixed by moving and engaging with a receiving portion 33 provided on the tool body 1 side.
つぎに、本発明の主要部分について、図４から図６に基づいて説明する。図４は、作業者が操作部３１を操作していない状態を示しており、左側の溝３５の周辺にはハウジング１６の長手方向に沿って順に、第一壁３７、第二壁３８が左側操作部３１Ａと略平行にスライド方向に延出している。同様に、右側の溝３５の周辺にもハウジング１６の長手方向に沿って順に、第三壁３９、第四壁４０が右側操作部３１Ｂと略平行にスライド方向に延出している。操作部３１は係合部３０と操作面３１ａと弾性体３２と左側操作部３１Ａと右側操作部３１Ｂとで構成されている。 Next, the main part of the present invention will be described with reference to FIGS. FIG. 4 shows a state in which the operator does not operate the operation unit 31. A first wall 37 and a second wall 38 are arranged on the left side of the left groove 35 in order along the longitudinal direction of the housing 16. It extends in the sliding direction substantially parallel to the operation portion 31A. Similarly, the third wall 39 and the fourth wall 40 also extend in the sliding direction in the vicinity of the right groove 35 in order along the longitudinal direction of the housing 16 in substantially parallel to the right operation portion 31B. The operation unit 31 includes an engagement unit 30, an operation surface 31a, an elastic body 32, a left operation unit 31A, and a right operation unit 31B.
図５は、作業者が操作部３１の中心軸（不図示）から紙面に対して左側を押圧している状態を示しており、弾性体の復元力を復元力Ｘ＞復元力Ｙと定義すると、この状態では操作部３１の左側の復元力が右側の復元力より大きい。左側操作部３１Ａの左端と右端は、それぞれ第一壁３７、第二壁３８とで接触部３６Ｂと接触部３６Ａで接する状態でスライド動作される。 FIG. 5 shows a state in which the operator presses the left side against the paper surface from the central axis (not shown) of the operation unit 31, and the restoring force of the elastic body is defined as restoring force X> restoring force Y. In this state, the restoring force on the left side of the operation unit 31 is larger than the restoring force on the right side. The left end and the right end of the left operation portion 31A are slid in a state where the first wall 37 and the second wall 38 are in contact with the contact portion 36B and the contact portion 36A, respectively.
図６は、作業者が操作部３１の中心軸（不図示）から紙面に対して右側を押圧している状態を示しており、弾性体の復元力を復元力Ｘ＞復元力Ｙと定義すると、この状態では操作部３１の右側の復元力が左側の復元力より大きい。右側操作部３１Ｂの左端と右端は、それぞれ第三壁３９、第四壁４０とで接触部３６Ｂと接触部３６Ａで接する状態でスライド動作される。 FIG. 6 shows a state in which the operator presses the right side of the paper surface from the central axis (not shown) of the operation unit 31, and the restoring force of the elastic body is defined as restoring force X> restoring force Y. In this state, the restoring force on the right side of the operation unit 31 is larger than the restoring force on the left side. The left end and the right end of the right operation portion 31B are slid in a state where the third wall 39 and the fourth wall 40 are in contact with the contact portion 36B and the contact portion 36A, respectively.
このような構成にすることによって、従来は、接触部３６Ａと３６Ｂとが離れた距離にあることで、操作部３１の中心軸上にあった回転軸に対する慣性モーメントが大きかったが、接触部３６Ａと接触部３６Ｂとの距離が小さくなり、左側操作部３１Ａもしくは右側操作部３１Ｂの中心軸に回転軸を移すことができるため、操作部３１をスライド動作させるときに、小さな力で操作することができる。 With this configuration, conventionally, the contact portions 36A and 36B are at a distance away from each other, so that the moment of inertia with respect to the rotation axis on the central axis of the operation unit 31 is large. And the contact portion 36B become smaller, and the rotation axis can be moved to the central axis of the left operation portion 31A or the right operation portion 31B. Therefore, when the operation portion 31 is slid, it can be operated with a small force. it can.
なお、上述の実施形態では、操作部３１が係合部３０と一体に形成されているが、係合部３０と連動するものであれば必ずしも一体に形成されている必要はない。 In the above-described embodiment, the operation unit 31 is formed integrally with the engagement unit 30. However, the operation unit 31 is not necessarily formed integrally as long as the operation unit 31 is interlocked with the engagement unit 30.
また、上述した実施例は、弾性体３２として圧縮バネを設けた場合の例であるが、弾性体３２はバネのほか、ゴム等であってもよい。 Moreover, although the Example mentioned above is an example at the time of providing a compression spring as the elastic body 32, the elastic body 32 may be rubber | gum etc. other than a spring.
尚、本発明の電池パック及び電池パックを備えた電動工具は、上述した実施の形態に限定されず、特許請求の範囲に記載した範囲で種々の変形や改良が可能である。 The battery pack and the electric tool including the battery pack according to the present invention are not limited to the above-described embodiments, and various modifications and improvements can be made within the scope described in the claims.
