〔考案の技術分野〕
本考案は、弾性体からなるブツシユ本体に、１
つもしくは複数個のリード線の通し孔を設けてな
るブツシングに関する。[Detailed description of the invention] [Technical field of the invention] The present invention has a bushing body made of an elastic body,
This invention relates to a bushing having one or more lead wire through holes.
従来のブツシングの原理を示す側断面図、正面
図を第１図ａ，ｂに表わす。
A side sectional view and a front view showing the principle of conventional bushing are shown in FIGS. 1a and 1b.
ブツシング１は弾性体たとえばゴムからなり、
リード線３を貫通させる孔２が穿設されている。 The bushing 1 is made of an elastic material such as rubber,
A hole 2 is bored through which a lead wire 3 passes.
リード線３はゴムブツシユ全体を通して圧迫さ
れ、シール性、固着性は強力なものとなる。 The lead wire 3 is compressed through the entire rubber bushing, resulting in strong sealing and adhesion.
第２図ａ，ｂ，ｃは従来例の側断面図、正面
図、上面図である。なお、ａはｂのＸ−X′に沿
う断面を示す。 Figures 2a, b, and c are a side sectional view, a front view, and a top view of the conventional example. Note that a represents a cross section along line X-X' of b.
この従来例は電動機用ブツシングで、電動機内
部から外部へ３本のリード線を導出するようにし
てあり、４，５は電動機外枠に係合する凹溝と突
起である。 This conventional example is a bushing for an electric motor, in which three lead wires are led out from inside the electric motor, and numerals 4 and 5 are grooves and projections that engage with the outer frame of the electric motor.
ところで従来からこれまでのブツシングでは、
シール性、固着性をよくするとリード線が通りに
くくなり、また加熱によりリード線に圧痕がつ
き、品質上問題があつた。
By the way, in the conventional bushing,
Improving the sealing and adhesion properties made it difficult for the lead wires to pass through, and the lead wires were left with impressions due to heating, which caused quality problems.
ここにおいて本考案は、従来手段の難点を克服
し、線通しも円滑でシール性も完壁なブツシング
を提供することを、その目的とする。
The object of the present invention is to overcome the drawbacks of conventional means and to provide a bushing that allows smooth wire passage and perfect sealing performance.
本考案は、ブツシユ本体内のリード線の通し孔
の挿入側内周面にテーパを設け、かつリード線と
接する出口側の周囲に同心状もしくはほぼ同心状
の溝を設けてなるブツシングである。
The present invention is a bushing in which the inner circumferential surface on the insertion side of the lead wire through hole in the bushing body is tapered, and a concentric or nearly concentric groove is provided around the outlet side in contact with the lead wire.
本考案の一実施例の側断面図、正面図を第３図
ａ，ｂに表わす。
A side sectional view and a front view of an embodiment of the present invention are shown in FIGS. 3a and 3b.
すべての図面において同一符号は同一もしくは
相当部分を示す。 The same reference numerals indicate the same or corresponding parts in all drawings.
リード線３は左側より右側へ矢印の方向へ挿入
する。 Insert the lead wire 3 from the left side to the right side in the direction of the arrow.
Ａ部はテーパ６を形成しており、その径はリー
ド外径ｄより大きく、容易にリード線３を導入す
ることができる。 Part A forms a taper 6, the diameter of which is larger than the lead outer diameter d, allowing the lead wire 3 to be easily introduced.
Ｂ部の通し孔２はリード線３の外径ｄより小さ
く、適当な締代を持つ。孔２の周囲、つまり出口
側の周囲に同心状もしくはほぼ同心状の溝７（そ
の内径Ｄ）を設ける。 The through hole 2 in the B section is smaller than the outer diameter d of the lead wire 3 and has an appropriate tightening margin. A concentric or nearly concentric groove 7 (its inner diameter D) is provided around the hole 2, that is, around the outlet side.
この溝７を具えたために、リード線３の外径ｄ
がバラついても、締代が大きくなつた場合でも、
リード線３を容易に孔２に通すことができ、また
リード線３の締代力も大きくならず、圧痕も付き
にくくなる。 Since this groove 7 is provided, the outer diameter d of the lead wire 3
Even if the torque varies or the tightening allowance increases,
The lead wire 3 can be easily passed through the hole 2, and the clamping force of the lead wire 3 is not increased, making it difficult to form impressions.
シール性は充分である。 Sealing performance is sufficient.
実験によると、リード線３の外径ｄと溝７の内
径Ｄの関係は
1.5≦Ｄ≦2d
程度が良いようである。 According to experiments, it seems that the relationship between the outer diameter d of the lead wire 3 and the inner diameter D of the groove 7 is about 1.5≦D≦2d.
なお、前記テーパ６および溝７はブツシユ本体
内に形成するので、軸方向の長さは従来と変わら
ず、余分なスペースをとることはない。 Incidentally, since the taper 6 and the groove 7 are formed within the bush main body, the length in the axial direction remains the same as in the conventional case, and no extra space is taken up.
第４図は、本考案の他の実施例を表わし、その
ａは側断面図、ｂは正面図、ｃは上面図、ｄは裏
面図である。 FIG. 4 shows another embodiment of the present invention, in which a is a side sectional view, b is a front view, c is a top view, and d is a back view.
この実施例は従来例の第２図を本考案により改
良したものである。 This embodiment is an improvement of the conventional example shown in FIG. 2 according to the present invention.
なお、ａはｂのＹ−Y′断面を示す。 In addition, a shows the YY' cross section of b.
このようにして、リード線が３本円滑に通し孔
２を左から右へ、テーパ６を経て導入させ、かつ
孔２の周囲には溝７が穿孔されているのでリード
線への締め付けが適正であり、しかも線通しが容
易となる。 In this way, the three lead wires are smoothly introduced through the hole 2 from left to right through the taper 6, and since the groove 7 is bored around the hole 2, the lead wires can be properly tightened. Moreover, the wire can be easily passed through.
かくして本考案によれば、シール性、固着性を
良くし、線通しの加工性も改善され、しかもブツ
シングの軸方向長さは何ら長くする必要はないの
で余分なスペースをとることもなく、この分野に
益するところ大きい。
Thus, according to the present invention, the sealing performance and adhesion performance are improved, and the workability of wire threading is also improved.Furthermore, the axial length of the bushing does not need to be increased at all, so it does not take up any extra space. It will greatly benefit the field.
