    • A joining element to be anchored in an object (10) with the aid of a thermoplastic material and mechanical vibration comprises a sealing portion (3.1) and a wall anchoring portion (3.2). The sealing portion (3.1) is substantially cylindrical and has a smooth circumferential surface. The wall anchoring portion (3.2) has a circumferential surface which comprises the thermoplastic material and energy directors. A cross section of the sealing portion (3.1) envelops the cross section (including energy directors) of the wall anchoring portion and is arranged adjoining to the latter on its proximal side. The joining element is anchored in an opening (5) provided in the object (10) wherein a cross section of the opening corresponds to the cross section of the sealing portion (3.1) of the joining element such that the latter can be forced into a mouth (5.1) of the opening (5) resulting in a press fit. For anchoring the joining element in the opening (5), mechanical vibrations e.g. ultrasonic vibrations are coupled into the joining element and the latter is forced into the opening (5) until at least a distal part of the sealing portion (3.1) is positioned within the opening. Thereby, the thermoplastic material of the circumferential surface of the wall anchoring portion (3.2) is liquefied and pressed into the opening wall, wherein the sealing portion (3.1) prevents the liquefied material to penetrate through the mouth and therefore the mouth (5.1) remains clear cut, i.e. does not get blurred by the liquefied material.
    • 通过热塑性材料和机械振动来锚定在物体(10)中的接合元件包括密封部分(3.1)和壁锚固部分(3.2)。 密封部分(3.1)基本上是圆柱形的并且具有光滑的圆周表面。 壁锚定部分(3.2)具有包括热塑性材料和能量导向器的圆周表面。 密封部分(3.1)的横截面包围壁锚定部分的横截面(包括能量导向器),并且在其近侧被布置为与其相邻。 接合元件锚定在设置在物体(10)中的开口(5)中,其中开口的横截面对应于接合元件的密封部分(3.1)的横截面,使得后者可以被迫进入 开口(5)的口(5.1)导致压配合。 为了将连接元件固定在开口(5)中,机械振动例如 超声波振动耦合到接合元件中,并且后者被迫进入开口(5),直到密封部分(3.1)的至少远端部分位于开口内。 因此,壁锚定部分(3.2)的圆周表面的热塑性材料被液化并压入开口壁中,其中密封部分(3.1)防止液化材料穿过口部,因此口(5.1)保留 清除切割,即不会被液化物弄脏。
