| Zusammenfassung: | The invention discloses a welding fixing assembly structure which is used for being fixed on a circuit board; an electroplating hole is formed in the circuit board; the welding fixing assembly comprises a rod body, an annular abutting portion, a fixing adhesive and an annular protruding portion. One end of the rod body is used for penetrating through the electroplating hole. The annular abutting portion is arranged on the rod body and is used for abutting against the circuit board, and an annular notch is formed in the bottom surface of the annular abutting portion. The fixing adhesive is usedfor filling between the annular abutting portion and the circuit board and between the circuit board and the rod body. The annular protruding portion is arranged on the rod body and is arranged belowthe annular abutting portion so as to prevent the fixing adhesive from overflowing downwards |
