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.

[What is claimed is:] [1.]wherein each conveyor hanger has at least two lower contacting devices secured to said hanger and each body carrier has at least four upper contacting devices secured to said carrier and adapted to be placed on said lower contacting devices,each lower contacting device having a support and contact element pointing upwards as well as a guide element arranged next to said support and contact element transversely to the direction of conveyance and likewise pointing upwards, andeach upper contacting device having a protective bell open at the bottom and storing a bubble of air in the submerged state,said protective bell having in the area of said bubble a downwardly concave, partially circular cylindrical support and contact surface adapted to be placed on a support and contact element and having a cylinder axis approximately horizontal and extending transversely to the direction of conveyance as well as on its outer side facing the guide element two locking elements forming a vertical opening between them for interacting with a locking nose on the guide element in order to make passage of the locking noses through the openings formed by the locking elements of the protective bells possible during placement of a body carrier on two conveyor hangers and to prevent any lifting of the protective bells away from the lower contacting devices during the inclined submergence of a body into the paint bath,said protective bell having at its outer side provided with the locking elements a rigid axle stub coaxial to the cylinder axis of its support and contact surface, andsaid guide element having for a lateral guidance of the axle stub an upwardly open guide slot parallel to the support and contact element of the lower contacting device,the side edges of said guide slot forming in the upper area of the guide slot insertion curves for the axle stub extending at an incline from top to bottom towards one another.
