Abstract
【解決手段】重合部32aを、直線状突部42bが形成された超音波溶着ベース42と、円環状突部43aが形成された超音波ホーン43とにより、直線状突部42b及び円環状突部43aの少なくとも一部が互いに対向した状態で挟み込んで超音波溶着する。これによれば、第1絶縁部32の重合部32aを超音波溶着する過程において、超音波ホーン43が超音波振動に伴って重合部32aに対して回転しても、超音波ホーン43に超音波振動を付与する前に比べて、重合部32aにおける直線状突部42b及び円環状突部43aの少なくとも一部が互いに対向した状態で挟み込まれる部分が少なくなってしまうことが無い。
【選択図】図7
Description
これによれば、絶縁部における撓み難い部位を極力小さくすることができる。また、絶縁部の延在方向において、ブリッジ基部は、絶縁部の他の部位に比べると、強度が高くなっている。そして、絶縁部の延在方向において、ブリッジ基部を含むように重合部を形成したため、絶縁部の他の部位に重合部を形成する場合に比べると、絶縁部における重合部での強度を確保することができる。
図1(a)に示す電動圧縮機10は、スクロール型電動圧縮機である。回転電機Mを構成する回転子11は、回転軸12に止着されており、回転電機Mを構成する固定子13は、モータハウジング14の内周面に嵌合して固定されている。電動圧縮機10を構成する圧縮動作体としての可動スクロール15は、回転電機Mを構成する回転軸12の回転によって旋回し、可動スクロール15と固定スクロール16との間の圧縮室17が容積減少する。
図7に示すように、超音波溶着装置41を用いて重合部32aを超音波溶着する際には、まず、第1絶縁部32における重合部32aの内周面を、超音波溶着ベース42の載置部42a上に載置する。
超音波ホーン43は、第1絶縁部32の重合部32aを超音波溶着する過程において、超音波振動に伴って重合部32aに対して回転する。しかし、超音波ホーン43に超音波振動を付与する前に比べて、重合部32aにおける直線状突部42b及び円環状突部43aの少なくとも一部が互いに対向した状態で挟まれる部分が少なくなってしまうことが無い。よって、安定した重合部32aの超音波溶着が行われ、重合部32aの溶着強度が確保される。
(1)重合部32aを、直線状突部42bが形成された超音波溶着ベース42と、円環状突部43aが形成された超音波ホーン43とにより、直線状突部42b及び円環状突部43aの少なくとも一部が互いに対向した状態で挟み込んで超音波溶着する。これによれば、第1絶縁部32の重合部32aを超音波溶着する過程において、超音波ホーン43が超音波振動に伴って重合部32aに対して回転しても、超音波ホーン43に超音波振動を付与する前に比べて、重合部32aにおける直線状突部42b及び円環状突部43aの少なくとも一部が互いに対向した状態で挟み込まれる部分が少なくなってしまうことが無い。よって、安定した重合部32aの超音波溶着を行うことができ、重合部32aの溶着強度を確保することができる。
○ 実施形態において、重合部32aが、第1絶縁部32の延在方向において、ブリッジ基部32kを含まない部位に形成されていてもよい。
○ 実施形態において、溶着部53が、重合部32aにおいて、ブリッジ片36の延在方向に位置する両縁部E3,E4まで延びるように形成されていてもよい。
○ 実施形態において、載置部42aを削除してもよい。この場合、超音波溶着ベース42の上面に直線状突部42bを形成する。
○ 実施形態において、円環状突部43aの数は特に限定されるものではない。
○ 実施形態において、第1絶縁部32の延在方向において、重合部32aの幅は、ブリッジ片36の幅よりも短くなっていてもよいし、重合部32aの幅がブリッジ片36の幅と同じであってもよい。
