The diversity of connector types with press-in terminations and varying termination styles make it necessary to have a simple, flexible tooling system that can be continuously updated.
The HARTING modular tooling system has significant advantages in terms
of economic assembly of the many connector types with press-in terminations.
The basic modules of the tooling system which will always be required are:
Press
Top tool
Bottom tool
To increase automation and productivity the following modules may be added to the basic assembly:
Guide frame with base plate for accurate positioning of the pcb up to a length of 600 mm
Guide frame "standard" for hand bench press and pneumatic press and pcb height of 123.5 up to 309.5 mm
Handling indications
When setting up an assembly machine it is not necessary to set the working height of the press and adjust the base plate more than once. There is no need for further adjustments. All the other adaptations for various applications are performed efficiently and are reliant by various combinations of individual modules.

The ram of the HARTING press is generally provided with a cross-shaped groove which accurately positions the top tool in steps of 90°. |

Range of applications for the bottom tool One bottom tool can be used to assemble connectors with straight or angled press-in terminations. When pressing in the connectors with angled press-in terminations the positioning pins remain in the bottom tool and serve as guide pins for the connector. By rotating the bottom tool in steps of 90° and relocating the positioning pins it is possible to assemble half-length connectors with angled press-in terminations. |

Bottom tool (narrow version) In addition to the square bottom tool with multifunctional properties, HARTING offers the alternative of a narrow bottom tool for assembling connectors with straight press-in terminations. This tool supports the pcb within the press-in connector zone and therefore makes it possible the assemble connectors where electronic components are to be placed in close proximity. |

Guide frame The guide frame screwed to the base plate ensures the correct positioning of the pcb in relation to the top and bottom tools and permits a much higher rate of assembly. Both guide rails are adjustable to accommodate various pcb sizes. A spring-loaded supporting rail lifts the pcb away from the bottom tool after the press-in operation ensuring that no damage occurs to the conductors as it passes through the machine. |
