なお、右側の対向板部１６の外面上部には、一方側係合部３６の係合部分４１を他方側係合部３７の両係合部分４６間の空間４５に挿入するための凹状部４０が設けられている。 Note that a concave portion 40 is provided on the upper outer surface of the right facing plate portion 16 for inserting the engaging portion 41 of the one side engaging portion 36 into the space 45 between the two engaging portions 46 of the other side engaging portion 37. is provided.

そして、例えば保持具１を複数使用する場合には、一の保持具１の一方側係合部３６と他の保持具１の他方側係合部３７との係合（嵌合）により、これら両保持具１同士が互いに連結固定される。 For example, when a plurality of holders 1 are used, the one side engaging portion 36 of one holder 1 and the other side engaging portion 37 of another holder 1 are engaged (fitted) to Both holders 1 are connected and fixed to each other.

つまり、一の保持具１の一方側係合部３６の係合部分４１の係合面４３と他の保持具１の他方側係合部３７の係合部分４６の係合面４９とが互いに係合するとともに、一の保持具１の一方側係合部３６の係合部分４１の下面と他の保持具１の他方側係合部３７の連設部分４８の上面とが互いに係合し、かつ、一の保持具１の一方側係合部３６の連結部分４２の上面と他の保持具１の他方側係合部３７の凸状部分４７の下面とが互いに係合することにより、これら両保持具１同士が横に並んだ状態に連結固定される（図８や図９参照）。 That is, the engagement surface 43 of the engagement portion 41 of the one side engagement portion 36 of one holder 1 and the engagement surface 49 of the engagement portion 46 of the other side engagement portion 37 of the other holder 1 are mutually At the same time, the lower surface of the engaging portion 41 of the one-side engaging portion 36 of one holder 1 and the upper surface of the connecting portion 48 of the other-side engaging portion 37 of the other holder 1 engage with each other. , and the upper surface of the connecting portion 42 of the one-side engaging portion 36 of one holder 1 and the lower surface of the convex portion 47 of the other-side engaging portion 37 of the other holder 1 engage with each other, Both of these holders 1 are connected and fixed in a side-by-side state (see FIGS. 8 and 9).

ここで、図８に示す連結例（使用例１）は、同じサイズ（定格電流）の複数本の電線体２をプリント基板７に接続する場合の例である。この例では、各保持具１は同じものである。他方、図９に示す連結例（使用例２）は、異なるサイズ（定格電流）の複数本の電線体２をプリント基板７に接続する場合の例である。この例では、各保持具１は、保持する電線体２の太さ（電線の直径）に応じて異なったものである。また、保持具１の個数は任意（極数は任意）であり、例えば１個や２個でもよく、５個以上でもよい。 Here, the connection example (use example 1) shown in FIG. 8 is an example in which a plurality of wire bodies 2 of the same size (rated current) are connected to the printed circuit board 7. In this example, each holder 1 is the same. On the other hand, the connection example (use example 2) shown in FIG. 9 is an example in which a plurality of wire bodies 2 of different sizes (rated currents) are connected to the printed circuit board 7. In this example, each holder 1 is different depending on the thickness (diameter of the wire) of the wire body 2 to be held. Further, the number of holders 1 is arbitrary (the number of poles is arbitrary), for example, it may be one or two, or it may be five or more.

そして、図１０に示すように、保持具１はプリント基板７に取り付けられて自立固定される。当該保持具１で保持された電線体２の中間部は、当該図１０の如くプリント基板７に対して平行状態（略平行状態を含む）となっている。また、当該保持具１で保持された電線体２の先端部のフェルール端子６は、プリント基板７に対して直交状態になっており、かつ、当該プリント基板７に導電部６ａが直接半田付けされて接続されている。なお、当該図１０中の５１は端子台であり、この端子台５１には、フェルール端子６ではなく丸型圧着端子５２が接続されている。 Then, as shown in FIG. 10, the holder 1 is attached to the printed circuit board 7 and is fixed independently. The intermediate portion of the wire body 2 held by the holder 1 is in a parallel state (including a substantially parallel state) to the printed circuit board 7 as shown in FIG. 10 . Further, the ferrule terminal 6 at the tip of the wire body 2 held by the holder 1 is perpendicular to the printed circuit board 7, and the conductive part 6a is directly soldered to the printed circuit board 7. connected. Note that 51 in FIG. 10 is a terminal block, and to this terminal block 51, not the ferrule terminal 6 but a round crimp terminal 52 is connected.

次に、保持具１の作用等を説明する。 Next, the operation of the holder 1 will be explained.

まず、フェルール端子付き電線である電線体２を保持具１に保持させる場合、作業者は、図７（ａ）及び（ｂ）に示すように、フェルール端子６の絶縁部６ｂが連結部１７の板厚部分１７ａの上面に当接するまで、フェルール端子６の導電部６ａを保持具１の保持孔部１２に挿入して差し込む。 First, when holding the electric wire body 2, which is an electric wire with a ferrule terminal, in the holder 1, the operator makes sure that the insulating part 6b of the ferrule terminal 6 is connected to the connecting part 17, as shown in FIGS. 7(a) and (b). The conductive portion 6a of the ferrule terminal 6 is inserted into the holding hole 12 of the holder 1 until it contacts the upper surface of the thick plate portion 17a.

続いて、作業者は、図７（ｃ）及び（ｄ）に示すように、保持孔部１２で保持されたフェルール端子６に対して電線５を湾曲状に弾性変形させつつ、当該電線５の中間部をその中間部が両第１凸部分２１間及び両第２凸部分２２間を順次通過するようにして両対向板部１６間の空間１５内に挿入する。その結果、電線５の中間部の絶縁被覆部５ｂが保持凸部１３で保持されて上方への移動が規制された横向きの水平状態となる。 Next, as shown in FIGS. 7(c) and 7(d), the operator deforms the electric wire 5 elastically into a curved shape with respect to the ferrule terminal 6 held in the holding hole 12. The intermediate portion is inserted into the space 15 between the opposing plate portions 16 so that the intermediate portion passes sequentially between both the first convex portions 21 and between both the second convex portions 22. As a result, the insulating coating portion 5b at the intermediate portion of the electric wire 5 is held by the holding convex portion 13 and placed in a horizontal horizontal state in which upward movement is restricted.

次いで、作業者は、図７（ｅ）に示すように、本体部１１の取付突部１８をプリント基板７の孔部（保持具用孔部）８に押し込むようにして挿入固定すると同時に、フェルール端子６の導電部６ａをプリント基板７の孔部（端子用孔部）９に挿入する。 Next, as shown in FIG. 7(e), the operator inserts and fixes the mounting protrusion 18 of the main body 11 by pushing it into the hole (holder hole) 8 of the printed circuit board 7, and at the same time inserts and fixes the ferrule. The conductive portion 6a of the terminal 6 is inserted into the hole (terminal hole) 9 of the printed circuit board 7.

その後、作業者は、フェルール端子６の導電部６ａをプリント基板７の回路（銅箔）に直接半田付けして固定する。こうして、電線体２の先端部のフェルール端子６の導電部６ａがプリント基板７の回路に電気的に直接接続される。 Thereafter, the operator directly solders and fixes the conductive portion 6a of the ferrule terminal 6 to the circuit (copper foil) of the printed circuit board 7. In this way, the conductive portion 6a of the ferrule terminal 6 at the tip of the wire body 2 is directly electrically connected to the circuit on the printed circuit board 7.

そして、保持具１によれば、取付突部１８によってプリント基板７に取り付けられる本体部１１と、本体部１１に設けられ、電線体２の先端部を保持する保持孔部１２と、本体部１１に設けられ、電線体２の中間部（電線体２の先端部付近の中間部）を保持する保持凸部１３とを備えるため、プリント基板７に対する電線体２の接続作業性の向上を図ることができ、しかも、プリント基板７への電線体２の接続安定性の向上も図ることができ、接続不良等の不具合を適切に防止できる。 According to the holder 1, the main body 11 is attached to the printed circuit board 7 by the mounting protrusion 18, the holding hole 12 is provided in the main body 11 and holds the tip of the wire body 2, and the main body 11 Since it is provided with a holding convex portion 13 that is provided at the wire body 2 and holds the intermediate portion of the electric wire body 2 (the intermediate portion near the tip of the electric wire body 2), the workability of connecting the electric wire body 2 to the printed circuit board 7 is improved. Moreover, it is possible to improve the connection stability of the electric wire body 2 to the printed circuit board 7, and it is possible to appropriately prevent problems such as poor connection.

また、本体部１１が取付突部１８でプリント基板７の表面に立ち姿勢で実装された状態で、保持孔部１２が電線体５の先端部をプリント基板７の表面に対して直交状態になるように保持し、かつ、保持凸部１３が電線体５の中間部をプリント基板７の表面に対して平行状態になるように保持するため、電線体２の接続作業性及び接続安定性の更なる向上を図ることができる。 Further, when the main body 11 is mounted in a standing position on the surface of the printed circuit board 7 using the mounting protrusion 18, the holding hole 12 makes the tip of the wire body 5 perpendicular to the surface of the printed circuit board 7. Since the holding convex portion 13 holds the intermediate portion of the wire body 5 parallel to the surface of the printed circuit board 7, the workability and connection stability of the wire body 2 are improved. It is possible to achieve further improvements.

さらに、本体部１１は、電線体５が挿入配置される空間１５を介して互いに離間対向する対向板部１６と、これら両対向板部１６同士を連結する連結部１７と、この連結部１７に突設された取付突部１８とを有し、かつ、保持孔部１２が連結部１７に設けられ、保持凸部１３が対向板部１６の内面に設けられた構成であるから、シンプルな構成にも拘わらず、電線体２の接続作業性及び接続安定性を適切に図ることができる。 Furthermore, the main body part 11 includes opposing plate parts 16 that face each other apart from each other via a space 15 into which the electric wire body 5 is inserted, a connecting part 17 that connects both of these opposing plate parts 16, and a connecting part 17 that The structure has a protruding mounting protrusion 18, the holding hole 12 is provided on the connecting portion 17, and the holding protrusion 13 is provided on the inner surface of the opposing plate portion 16, so the structure is simple. Nevertheless, the connection workability and connection stability of the wire body 2 can be appropriately achieved.

また、本体部１１は、一方側係合部３６及び他方側係合部３７を有し、保持具１を複数使用する場合には、一の保持具１の一方側係合部３６と他の保持具１の他方側係合部３７との係合により、これら保持具１同士を互いに連結できるため、電線体２の本数（極数）やサイズ等に適切に対応できる。よって、例えば要望の極数（電線数）に合わせて同寸法ピッチ・横並べ構造を取ることで、高密度化された多連コネクタ等への応用も可能である。 Moreover, the main body part 11 has one side engaging part 36 and the other side engaging part 37, and when using a plurality of holders 1, the one side engaging part 36 of one holder 1 and the other side engaging part 36 are connected to each other. Since these holders 1 can be connected to each other by engaging with the other side engaging portion 37 of the holder 1, it is possible to appropriately correspond to the number (number of poles), size, etc. of the electric wire bodies 2. Therefore, it is possible to apply it to a high-density multiple connector, for example, by adopting a horizontally arranged structure with the same pitch and dimensions in accordance with the desired number of poles (number of wires).

なお、保持具は、電線体であるフェルール端子付き電線のフェルール端子を保持するのに適したものであるが、電線体は、フェルール端子付き電線には限定されず、例えばフェルール端子等が付いていない単線や撚り線等でもよい。 Note that the holder is suitable for holding the ferrule terminal of an electric wire with a ferrule terminal, which is an electric wire body, but the electric wire body is not limited to an electric wire with a ferrule terminal. It may be a single wire or a twisted wire.

また、複数本の電線体をプリント基板に接続する際には複数の保持具を用意してそれらを互いに連結する構成について説明したが、例えば複数の保持具を予め一体化した構成等でもよい。 Moreover, although a configuration has been described in which a plurality of holders are prepared and connected to each other when connecting a plurality of electric wire bodies to a printed circuit board, for example, a configuration in which a plurality of holders are integrated in advance may be used.
