Electrical contacting system for an electrophoretic dip painting plant for motor vehicle bodies

摘要

Electrical contacting system for an electrophoretic dip painting plant for motor vehicle bodies, where the bodies are guided through an electrophoretic dip paint bath by an overhead conveyor having hangers for engaging beneath the body carriers. Each conveyor hanger has at least two lower contacting devices secured thereto and each body carrier has at least four upper contacting devices secured thereto. Each upper contacting device has a protective bell open at the bottom and storing an air bubble in the submerged state. In the area of the air bubble the bell has a downwardly concave, partially circular cylindrical support and contact surface and has a horizontal cylinder axis extending transversely to the conveyance direction. At its outer side facing the guide element, two locking elements form a vertical opening therebetween to interact with a locking nose on the guide element where the locking noses pass through the openings formed by the locking elements. To ensure a secure locking of the protective bell on the lower contacting device, a system is designed where the protective bell is provided with the locking elements having a rigid axle stub coaxial to the cylinder axis of its support and contact surface. The guide element has an upwardly open guide slot parallel to the support and contact element of the lower contacting device. The side edges of this slot forming insertion curves for the axle stub which extend at an angle towards one another from top to bottom.
