Abstract
A split bus assembly is provided for a heat-sealing machine. The split bus assembly includes a clamp with first and second clamp segments that abut each other in face-to-face engagement. The engaging surfaces or inner walls of the clamp segments may be coated with a nonconductive material so that the clamp segments are electrically insulated with respect to each other. A tab terminal may be defined at each inner wall, constituting a zone of exposed conductive material which is configured to engage a conductive tab of a heat-seal band during use. Biasing members such as a silicone spring may be arranged in the tool to facilitate ejection of the heat-seal band during a removal procedure. The tool may be cooled by way of cooling fluid that flows through passages in the bus bars.
Claims15
A heat-seal tool for providing electrical energy to a heat-seal band, the heat-seal tool comprising:
- a first bus bar toward a first segment of the heat-seal band that electrically connects a first load current conductor to a first tab of the heat-seal band;
- a second bus bar toward a second segment of the heat-seal band that electrically connects a second load current conductor to a second tab of the heat-seal band;
- a clamp configured to hold the heat-seal band, the clamp including:
- a first clamp segment that presents a first electrically insulated surface toward the first tab of the heat-seal band;
- a second clamp segment that presents a second electrically insulated surface toward the second tab of the heat-seal band;
- and
- an abutment joint defined by face-to-face engagements of respective surfaces of:
- the first clamp segment and the first tab;
- and
- the second clamp segment and the second tab.
A heat-seal tool comprising:
- a first bus bar that is electrically connected to a first load current conductor;
- a second bus bar that is electrically connected to a second load current conductor;
- and
- a cooling system that is configured to convey a cooling fluid through at least one of the first and second bus bars.
