(31 is a cap made of silicone rubber, and a resin such as epoxy resin (31) is connected to the cap.
It is insulated by injecting it with a cap and covering it over the armature coil connection part (c) like a hat, then hardening it.

Square tubes (7) as shown in Figure V-6 are increasingly being used. This square tube (7) is generally made of a molded product such as glass mud polyester resin. It is also possible to make a cap made of silicone rubber (, ?+) in the same shape as a molded product made of glass mud polyester resin or the like.

ために、−通りの作業方法で一般化することはむずかし
いのが現状である。Seven of these limitations are that there is enough space to insert the square tube (W) into the armature coil connection (C);
This is necessary above Ha. In other words, unless the height A of the upper space shown in Figure DA is approximately greater than the height A/ of the square pipe, it cannot be inserted after the inter-electrode connecting wire (6) is attached. become. This kind of thing is
This can be solved by setting the assembly order correctly, but for example, when it comes to large rotating electric machines such as water turbine generators, the stator core (SL) is often manufactured by dividing it, or factory testing is difficult. The current situation is that it is difficult to generalize the work method as it goes through complicated processes such as once assembled for transportation, then disassembled for transportation, and then reassembled on site.

自身を大形化されるという問題点を有していた。For this reason, the inter-electrode connecting wire (41) is arranged with a height A of the space that allows the square tube [7] to be inserted even after it is assembled, and as a result, However, there was a problem in that the armature coil end became large and the rotating electric machine itself became large.

い回転電機の電機子巻線を提供することを目的とする。This idea was made in order to solve the above-mentioned problems with armature coils in conventional rotating electric machines. To provide an armature winding for a rotating electrical machine that allows a square tube to be installed without increasing the size of the armature coil end and the rotating electrical machine.

きる。Since the square tube or cap according to the present invention is divided in the longitudinal direction of the connecting portion, the height is lowered and the square tube can be freely inserted into the connecting portion, and the position corresponding to the divided portion is Since the one-divided portion is insulated and separated, sufficient insulation properties can be ensured in the divided portion.

以下、この発明をその一実施例を示す図に基づいて説明
す°る。Embodiment] Hereinafter, the present invention will be explained based on the drawings showing one embodiment of the invention.

。Fig. 1 is a side view of the connecting device corresponding to Fig. It is a cross-sectional view.
図において、角管（ｌ／）は、例えば、角管上部（／２

幅に増大させている。Adhesive is applied to the split part (/ri) where the upper part of the square tube (/C) and the lower part of the square tube (/J) meet when it is inserted, but the thickness of the square tube (//) Since it is not that thick, the adhesive layer at the split part (/da) cannot be said to be reliable as an insulating material.On the other hand, the armature coil connection part (c) is grounded, as can be seen from Figure 9. Because it is located far away from the stator core (1s), very strong (high withstand voltage) insulation is not required, but the location where the water turbine generator etc. is installed is prone to dust, dirt, moisture, etc. Therefore, it is necessary to at least improve the airtightness between the conductor and the insulating surface to avoid short-circuiting between the conductor and the insulating surface due to dirt, dust, moisture, etc. The divided part insulating member C/S) is placed at a position facing the divided part (/), and by providing this, the divided part (//) of the square tube (//) can be separated from the conductor.

この実施例は上記のように構成されるが、その角管の取
付要領を次に説明する。This embodiment is constructed as described above, and the procedure for attaching the square tube will be explained next.

レジン（ゲ）を角管下部（／３）の上端近くまで注入す
る。In the embodiment shown in Figs. 1 and 2, first, the lower part of the square tube (/J) is inserted into the armature coil connection part (C), and after sealing with resin (not shown in the figure), Inject epoxy resin (Ge) to near the top of the lower part of the square tube (/3).
このエポキシレジン（ｕｌが硬化する前に、角管状に作

同じくなるように平均に押し込む。Before this epoxy resin (ul) hardens, place the divided part insulating member (15) made in the shape of a square tube into the square tube (//) at a position corresponding to the divided part (/II) of the square tube (ll). Push in evenly so that the distances are the same and the distances from the upper and lower ends of the dividing part (/) are the same.
このような状態でエポキシレジン（ダ１を硬化させたの

部（／コ）に注入し硬化させて完成する。In this state, after curing the epoxy resin (da 1), apply adhesive (epoxy resin is fine) to the upper end of the lower part of the square tube (/3) and insert the upper part of the square tube (/3). The upper part of the tube (/2) and the lower part of the square tube (/3) are glued together, and after this adhesion is almost complete, epoxy resin (&) is injected into the upper part of the square tube (/) and cured to complete the process.
このようにすることによって、例えば極間接続線と角管
（／／）との間のスペースの高さＡｕは角管下部（／３
）の高さＡ３および角管上部（／２）の高さＡｌに相当
する高さで良いことになる。By doing this, for example, the height Au of the space between the electrode connection line and the square tube (//) can be reduced to the lower part of the square tube (/3
) and the height A1 of the upper part of the square tube (/2) will suffice.

この作業と極間接続線（６）の取付作業とを並行作業に
することができる等のメリットもあり、作業性を阻害す
るものではない。In this invention, although it may seem like a complicated process, in general, the epoxy resin is
- If cured in one step, foaming or curing problems may occur, so it is common to cure in three steps, so it is not particularly complicated.
There is also an advantage that this work and the work of attaching the inter-electrode connecting wire (6) can be done in parallel, and the work efficiency is not hindered.
なお、分割部絶縁部材（１５）は色々な方法で製作可能
であり、例えば、角管（／／）と同様なガラスマッドポ
リエステル等の成形品としてもよく、また、厚手ノーメ
ックスシートを角管状に成形接着して作ること等が考え
られる。The divided part insulating member (15) can be manufactured in various ways, for example, it can be made of glass mud polyester similar to the square tube (//), or it can be made from a thick Nomex sheet into the shape of a square tube. It is conceivable to make it by molding and adhering.
また、上記実施例では分割部絶縁部材（１５）を角管状

回して構成することもできる。In addition, in the above embodiment, the divided part insulating member (15) is made into a square tube, but insulating tape is applied to the armature coil connection part (11) at the position corresponding to the divided part (11) of the square tube (11). It can also be configured by winding.
更に、分割部絶縁部材（／Ｓ）は角管（／／）の分割部
（／す）の外側に配置することもできる。Furthermore, the divided part insulating member (/S) can also be arranged outside the divided part (/S) of the square tube (//).
