The assembly can be adapted to be coupled to the accessory to permit the appliance to pivot relative to the accessory about two independent axes. The swivel system can include a vacuum adapter and a connector adapted to permit the vacuum adapter to pivot about a vacuum accessory. A plenum chamber can be formed in the adapter that is in fluid communication with one or more vacuum hoses to balance the airflow within the adapter. With the swivel systems and assemblies described herein, the versatility and efficiency of vacuum appliances and other tools can be improved through their multi-axes rotational capabilities and balanced airflow configurations.
A hermetic power terminal feed-through for use in high-pressure applications is disclosed as including a fused pin subassembly includes a tubular reinforcing member and a current-conducting pin. The pin passes through the tubular reinforcing member and is fixed thereto by a fusible sealing material to create a hermetic seal. The fused pin subassembly is then joined and hermetically sealed to a terminal body. A method for manufacturing the high-pressure hermetic power terminal feed-through is also disclosed.
H01R 43/16 - Apparatus or processes specially adapted for manufacturing, assembling, maintaining, or repairing of line connectors or current collectors or for joining electric conductors for manufacturing contact members, e.g. by punching and by bending
