"以雄榫连接" can be translated as "connected with a male tenon" or "joined by a male tenon" in English.
Here, “雄榫” (xióng sǔn) refers to the male part of a tenon-and-mortise joint in carpentry or woodworking, which fits into the corresponding female part (the mortise). So, the translation emphasizes the specific type of connection using the male tenon.
