NOVELTY - Apparatus for position fixing of a connector (3) on a solar cell (2), by a down-holder, comprises: a conveyor belt (1) for moving the solar cell and the connector to a processing station, where the down-holder has a framework provided with retaining elements, for synchronously moving towards the conveyor belt, and the framework is formed as a stainless spring-like clamping frame with its longitudinal sides arranged transversely to the conveying direction of the conveyor belt; and at least one flexible down-holder-wire (5) arranged between the end faces parallel to the conveyor belt.    USE - The apparatus is useful for position fixing of a connector made of tinned solder strip, on a solar cell by a down-holder lowered on the connector during transportation in a manufacturing plant for producing solar cell strings.    ADVANTAGE - The apparatus: ensures a quasi-linear contact pressure on the connector in both transversely and longitudinally to the conveying direction, independently from each other; compensates for unevenness of cells and connectors at the support points, and -a type-dependent conversion of the down-holder in different storage positions and dimensions of the connector at the same time; reduces technical complexity in machines; enhances the throughput and quality; and maintains a high flexibility.    DETAILED DESCRIPTION - Apparatus for position fixing of a connector (3) made of tinned solder strip on a solar cell (2) by a down-holder lowered on the connector during transportation in a manufacturing plant for producing solar cell strings, comprises: a conveyor belt (1) driven by a drive, for moving the solar cell and the connector to a processing station, where the down-holder has a framework provided with retaining elements, for synchronously moving towards the conveyor belt, and the framework is formed as a stainless spring-like clamping frame with its longitudinal sides arranged transversely to the conveying direction of the conveyor belt; and at least one flexible down-holder-wire (5) arranged between the end faces parallel to the conveyor belt and transverse to the connector, and is held under tension in a frame box of the clamping frame. The down-holder-wire has at least one contact unit (6), for linear pressing of the connector at the solar cell during the lowering.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic perspective view of the apparatus fitted to a solar cell provided with connectors.
