Vibration welded joint structures, methods, and apparatus for thermoplastic members are disclosed. A welded joint structure includes first and second thermoplastic members and an interposed junction piece vibratory welded to the first and second members at respective welding surfaces. At least one of the welding surfaces partially defines an angle, in a plane normal to the interposed junction piece, between an unwelded portion of the first member and an unwelded portion of the second member. The junction piece may include surfaces for forming vibratory welded bonds with the first and second thermoplastic members and a component holder, physically coupled to those surfaces, for enabling the junction piece to hold a further component.
La présente invention concerne des structures, des procédés et des appareils de joints soudés par vibrations, pour des éléments thermoplastiques. Une structure de joint soudé comprend un premier et un second élément thermoplastique, ainsi qu'un élément de jonction interposé, soudé par vibrations au premier et au second élément, sur des surfaces de soudage respectives. Au moins l'une des surfaces de soudage définit partiellement un angle, dans un plan normal à l'élément de jonction interposé, entre une partie non soudée du premier élément et une partie non soudée du second élément. L'élément de jonction peut inclure des surfaces pour former des liens soudés par vibration avec le premier et le second élément thermoplastique et un support de composant, physiquement raccordé à ces surfaces, pour permettre à l'élément de jonction de maintenir un autre composant.
