Method for inspecting the quality of a crimp connection and system therefor

Method according to one or more of the preceding claims, characterized in that the tensile strength is determined by means of a control unit (17) connected to the sensor unit and/or by means of a mobile handheld device (4) connected to a communication unit (18) of the handheld pulling and compressing device (3) via a transmitting and receiving unit and/or by means of a server unit (21) connected to the handheld pulling and compressing device (3) or the mobile handheld device (4) via a wireless connection.

Method according to one or more of the preceding claims, characterized in that the tensile force and/or the adjustment travel is recorded over a definable inspection duration and the recorded data is compared with reference data stored in the mobile handheld device (4) or in a database (23) of the server unit (21) in order to inspect the quality of the crimp connection (2).

Method according to one or more of the preceding claims, characterized in that the cable (22) for selecting a crimp contact (25) suitable for producing the crimp connection (2) is identified by means of the mobile handheld device (4) and information on the suitable crimp contact (25) is displayed on a display unit (19) of the mobile handheld device (4).

Method according to one or more of the preceding claims, characterized in that for identification of the cable (22)

• an electronic image of the cable (22) to be identified is created with a camera unit of the mobile handheld device (4),
• the electronic image is transmitted to an evaluation unit (24) of the server unit (21) via the transmitting and receiving unit for identifying the cable (22) in the server unit (21) by comparison with images of cables (22) to be identified stored in the database (23), and
• the information stored for the identified cable (22) in the database (23) is transmitted to the handheld device (4) for selection of the suitable crimp contact (25).

Method according to one or more of the preceding claims, characterized in that the information on the crimp contact (25) suitable for producing the crimp connection (2) is stored in the database, the suitable crimp contact (25) is selected on the basis of the identified cable (22) by means of the evaluation unit (24), and the information is transmitted to the mobile handheld device (4) for display on the display unit (19).

Method according to one or more of the preceding claims, characterized in that for identification of the cable (22) in the mobile handheld device (4) or in the evaluation unit (24), the shape type of the cable (22) and/or at least one object marking of a label arranged on the cable (22) to be identified is determined by automatic shape detection of the electronic image.

Method according to one or more of the preceding claims, characterized in that a value corridor is stored as reference data in the database (23) of the server unit (21), the detected tensile forces and/or the adjustment travel in the evaluation unit (24) are compared with the value corridor, and if the detected tensile forces and/or the adjustment travel deviate from the value corridor, an error message is displayed on the display unit (19) of the mobile handheld device (4).

Method according to one or more of the preceding claims, characterized in that information on crimping punches (5), crimping dies (6), crimp holders (7) and/or cable holders (8) is stored in the database (23) of the server unit (21) or on the mobile handheld device (4), a suitable crimping punch (5) and a suitable crimping die (6) and/or a suitable crimp holder (7) and a suitable cable holder (8) are selected by means of the identified cable (22) for the production and/or inspection of the crimp connection (2), and the information stored for this purpose is displayed on the display unit (19) of the mobile handheld device (4).
