Kolombat; J. Kokaegner application (patent) No. 03806612.2 Date of application 2003.03.19 Certification date Approval notice No. 1642744 Date of validation announcement 2005.07.20 Manual CD No. D0529 Main classification number B41J2/175 Classification No. B41J2/175; B41J29/38 Classification Original application No. 2002.3.22 FR 02/03605 Abstract The present invention relates to an ink-jet printer, characterized in that the connection part (1) of the umbilic which is connected to the connection part of the print head of the printer comprises: some first devices (12, 13, 14). ,15,17,18,20-23,25) and second devices (12,14,15,16,25) for positioning the electrical terminals (13,19) and hydraulic terminals (24) of the umbilical cord, these The device is mechanically connected to the connection portion (1) of the umbilical cord; a number of third (12, 28) and fourth (31, 48) devices for positioning are mechanically connected to the connection portion (3) of the umbilical cord and the print head. The third positioning device (12, 28) and the fourth positioning Means (31 and 48) with opposing to the connecting portion (1) positioning the connecting portion of the umbilical cord of the printhead. The connection of the umbilical on the print head is achieved by a single translational movement. Sovereignty item 1. Inkjet printer comprising a print head having a print head connection (3) to connect the electrical and hydraulic ends of the print head to electrical connections to the hydraulic circuit and to the printer The conductor-connected connection umbilical, which is provided with a connection end (1), which brings together the end of the hydraulic circuit and the end of the electrical conductor, is characterized in that the connecting portion (1) of the umbilical cord comprises:- A first positioning device is mechanically connected to the connecting portion (1) of the umbilical cord so as to position the electrical end portion in the connecting portion (1) of the umbilical cord, some second positioning means, and a connecting portion thereof with the umbilical cord ( 1) mechanically connected to position the hydraulic end in the connecting part (1), - a number of third positioning means (12, 28) which are mechanically connected to the umbilical cord, the connecting part of the print head being provided with: - the The base (31) of the main body (34) of the print head, the base (31) bringing together the ends (36) of the hydraulic lines of the print head and the ends of the electrical conductors mechanically positioned relative to the base (31). The printhead opening (36) has a pre-position on the base (31) Position, - a fourth positioning device mechanically connected to said connecting portion (3) of the print head, in a position where the umbilical cord is connected to the print head, - third (12, 28) and fourth (31, 48) The connecting device cooperates to position the connecting portion (1) of the umbilical cord with respect to the connecting portion (3) of the print head through the first positioning device (12, 13, 14, 15, 17, 18, 20-23, 25) The electrical end (19) of the umbilical cord positioned in the connecting portion (1) of the umbilical cord is located in the connecting position of the umbilical cord and the print head, the position contacting the electrical conductor positioned mechanically relative to the base (31). The end (39), the hydraulic end (24) of the umbilical cord of the umbilical cord positioned by the second positioning means (12, 14, 15, 16, 25) of the umbilical cord is located at the extension of the hydraulic end (36) of the base Hereby, there is formed a sealed communication between the hydraulic end of the umbilical and the hydraulic end of the pipe of the body of the printhead.
