Ultrasonic welding of electrical plug |
摘要 |
A method of ultrasonic welding of plastic members to form a high strength interconnection between the members in the form of a low profile electrical plug. High-frequency (ultrasonic) energy is transmitted by the ultrasonic welding apparatus to compatible plastic parts of the low profile electrical plug. At the intersection of the two parts, a combination of applied force and surface and/or intermolecular friction increases the temperature until the melting point of the thermoplastic is reached. Upon removal of the ultrasonic energy, a bond is produced between the plastic parts, effectively affixing them together in the desired fashion. Typical systems used for ultrasonic welding contain a high-frequency power supply (20-40 kHz). Energy from the power supply is directed into a horn dimensioned to be resident at the applied frequency. Upon contact with the workpiece, the horn transmits the energy into it. The two parts to be welded are aligned in the proper fashion by a support constructed of aluminum or steel.
