Abstract

يتعلق الاختراع بموصل مسنن threaded connector يتضمن طرف دبوسي pin end به أسنان خارجية external threads وطرف صندوقي box end به أسنان داخلية internal threads مكملة للأسنان الخارجية له هيئة سن thread profile التي تحدد على الأقل جزء من أي من أو كل من الأسنان الداخلية والأسنان الخارجية. يمكن أن تتضمن هيئة السن قاعدة سن thread root تصل جانب أول بجانب ثاني ويمكن تحديد قاعدة السن جزئيا على الأقل بواسطة مجموعة من أنصاف أقطار متصلة بينيا بشكل تماسي. يمكن أن تتضمن مجموعة أنصاف الأقطار على الأقل نصف قطر متوسط، نصف قطر بعيد أول على أحد جوانب نصف القطر المتوسط، ونصف قطر ثاني بعيد على الجانب الآخر لنصف القطر المتوسط. يمكن أن يكون نصف القطر المتوسط أكبر من نصف القطر الأول والثاني البعيد. بشكل بديل، تتضمن هيئة السن قاعدة سن تصل جانب أول بجانب ثاني محدد جزئيا على الأقل بواسطة مجموعة من أنصاف أقطار، كل نصف قطر له طول مختلف وكل منها يحدد قوس دائري circular arc. شكل3
