[0002] EPSON-S3200 printheads are used in more and more scenarios in the digital printing industry. As a key component, the drive line connected to the printhead has high requirements. The S3200 printhead data cables on the market are as follows: Figure 1 The FPC flexible circuit board (10) shown in the figure is made in the form of welding, the FPC flexible circuit board (10) and the PCB board (20) are combined into one, and the PCB board is welded together with the nozzle / card connector (30), thereby forming a complete nozzle data line. Such a data line has the following defects:

[0003] (1) FPC flexible circuit boards are made by copper-clad etching, with the interior etched into a relatively dense copper wire, which is then soldered to the PCB. The yield rate is relatively low during the etching process, especially when longer data lines are required, and the yield rate drops sharply, resulting in higher manufacturing costs.

[0004] (2) The FPC flexible circuit board has a flat and wide structure, which requires a relatively high space for the data line during use. The FPC cannot be bent significantly, that is, it cannot be folded in half, and the connection between the line body and the connector cannot be twisted and rotated arbitrarily. Finally, the line cannot be arranged in a good state. These shortcomings greatly limit the use of the machine, especially in the scenario where a large number of nozzles are installed in a limited space. Utility Model Content

[0005] The nozzle data cable provided by the utility model aims to solve the problems in the prior art of low yield ratio and high manufacturing cost due to complex process and the problem that the material cannot be folded or twisted arbitrarily, which limits the use of the machine in a limited space.

[0007] Furthermore, the wire body portion also includes a flexible wrapping member wrapped around the data wire harness and the outside of the wire.

[0008] Furthermore, the connecting part includes a PCB board, a first connector is provided on the PCB board, the data harness and the wire are electrically connected to the PCB board, and the first connector is used to connect a nozzle or a board.

[0009] Furthermore, a second connector is also provided on the PCB board, and the data harness and the wires are both connected to the second connector.

[0010] Furthermore, the nozzle data cable also includes a protective cover covering the outside of the connecting portion, and the protective cover is provided with a first avoidance groove corresponding to the first connector and a second avoidance groove for the wire and the data harness to extend out of the protective cover.

[0011] Furthermore, the first avoidance groove is surrounded by a periphery extending in a direction away from the protective cover to form a skirt, and the skirt can abut against the surface of the nozzle or the board.

[0012] Furthermore, the skirt is provided with protrusions on two opposite sides in the length direction thereof, and the protrusions extend along the length direction of the skirt.

[0013] Furthermore, the skirt is provided with protrusions on two opposite sides in the length direction thereof, and there are at least two protrusions on each side, and at least two protrusions are arranged at intervals along the length direction of the skirt.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figure 2 The embodiment of the utility model provides a nozzle data cable for digital printing equipment. The nozzle data cable includes a wire body 1 and connecting parts 2 arranged at both ends of the wire body 1. The connecting part 2 is used to connect a nozzle or a board, that is, the connecting part 2 at one end of the wire body 1 is connected to the nozzle / board, and the connecting part 2 at the other end is connected to the board or the nozzle. The wire body 1 includes a data harness 11 for data transmission and a wire 12 for power supply. Both ends of the data harness 11 and the wire 12 are connected to the connecting part 2.

[0024] The line body 1 is composed of two parts, namely a data harness 11 for data transmission and a wire 12 for power supply. Since both the data harness 11 and the wire 12 are flexible wires that can be folded and bent at will, wiring is convenient, and a suitable line length can be selected according to actual needs. This solves the limitation of line length caused by the process in traditional practices, optimizes the assembly method in the production process, improves the yield rate, and has low cost.

[0025] In this embodiment, the data wire harness 11 is a flexible coaxial wire.

[0026] See also Figure 2 Furthermore, the cable body 1 further includes a flexible wrapping member 13 wrapped around the outside of the data harness 11 and the wire 12. The flexible wrapping member 13 can integrate the wire 12 and the data harness 11 into an integrated structure, which can avoid the data harness 11 and the wire 12 from being scattered in a messy manner in practical applications, facilitate the wiring distribution to avoid the wires from being crossed and knotted, and improve the neatness of the wiring space, and can also protect the data harness 11 and the wire 12. In this embodiment, the flexible wrapping member 13 can be, but is not limited to, a braided rope, soft rubber, etc.

[0027] See also Figure 2 Further, the connecting part 2 includes a PCB board 21, on which a first connector 22 is provided. The data harness 11 and the wire 12 are electrically connected to the PCB board 21, so as to transmit data between the board and the nozzle through the PCB board 21 and to supply power to the nozzle at the same time. The first connector 22 is used to connect the nozzle or the board, that is, the first connector 22 of the connecting part 2 at one end of the wire body 1 is connected to the nozzle or the board, and the first connector 22 of the connecting part 2 at the other end is connected to the board or the nozzle.

[0028] See also Figure 2 Furthermore, the PCB board 21 is also provided with a second connector 23, and the data harness 11 and the wire 12 are both connected to the second connector 23. In this way, the data harness 11 and the wire 12 are connected to the PCB board 21 by plugging through the second connector 23. Compared with the traditional welding connection method, if an abnormality is found in the wire body 1 during the final inspection of the product, it can be replaced in time to reduce loss. At the same time, it can also facilitate the installation of the wire body 1 and the connecting part 2, simplify the installation process, improve the production efficiency, and reduce the production cost.

[0029] In this embodiment, there are two groups of wires 12 as positive and negative electrodes for power supply. Three second connectors 23 are provided on each connecting portion 2. The two groups of wires 12 and the data harness 11 are electrically connected to one second connector 23 respectively.

[0030] See also Figure 2 Furthermore, the nozzle data cable also includes a protective cover 3 covering the outside of the connecting part 2. The protective cover 3 can protect the connecting part 2 to prevent the connecting part 2 and the connector between the connecting part 2 and the line body 1 from being exposed to the outside, thereby causing damage by impact or adhesion of dust, ink and other liquids to cause corrosion or short circuit, thereby increasing the IP protection level and extending the service life of the nozzle data cable in an industrial environment. The protective cover 3 is provided with a first avoidance groove 31 corresponding to the first connector 22 and a second avoidance groove 32 for the wire 12 and the data harness 11 to extend out of the protective cover 3. The first avoidance groove 31 enables the wire 12 and the data harness 11 to extend out of the protective cover 3, and the second avoidance groove 32 enables the first connector 22 to be connected to the nozzle or the board.

[0031] See also Figure 3Furthermore, the first avoidance groove 31 extends around the direction away from the protective cover 3 to form a skirt 311, which can abut against the surface of the nozzle or the board. The skirt 311 supports the protective cover 3 and the nozzle (or the board) to support the weight of the entire nozzle data line, thereby preventing the weight of the nozzle data line from being borne by the first connector 22, thereby causing the first connector 22 to be deformed or crushed, resulting in transmission failure. In addition, the abutment of the skirt 311 with the nozzle can avoid the formation of a gap between the nozzle and the protective cover 3, thereby preventing ink from entering the gap between the nozzle and the first connector 22.

[0032] See also Figure 3 Further, the skirt 311 is provided with protrusions 3111 on opposite sides of the length direction thereof, that is, the protrusions 3111 are provided on the long sides of the skirt 311, and the protrusions 3111 extend along the length direction of the skirt 311. Providing the protrusions 3111 can increase the contact area between the skirt 311 and the nozzle or the board in the width direction, and avoid the tilt of the connection between the first connector 22 and the nozzle or the board when the nozzle data line is subjected to external force or inertia, thereby affecting the poor contact between the first connector 22 and the nozzle or the board. In addition, in addition to providing a continuous structure, the protrusions 3111 can also be provided with a spacing structure, specifically, there are at least two protrusions 3111 on each side, and at least two protrusions 3111 are spaced along the length direction of the skirt 311, so that the contact area between the skirt 311 and the nozzle or the board in the width direction can also be increased, and the overall weight of the skirt 311 can also be reduced.

[0033] In this embodiment, the protrusion 3111 adopts a spaced-apart structure, and there are two protrusions 3111, that is, two protrusions 3111 are respectively arranged on the opposite sides of the skirt 311 in the length direction. The two protrusions 3111 can be arranged as far away from the center line of the long side as possible. In this way, the area surrounded by the protrusions 3111 on the opposite sides can be increased, thereby improving the anti-tilt ability of the first connector 22.

[0034] In this embodiment, the protrusion 3111 can be disposed on the outer surface of the skirt 311 , so that the protrusion 3111 can avoid occupying space in the first avoidance groove 31 .

[0035] See also Figure 2 Specifically, the protective cover 3 includes a first cover body 3a and a second cover body 3b that are covered and connected, which facilitates the processing and installation of the protective cover 3. The space formed by the second cover body 3b and the second cover body 3b is filled with curing glue, which can protect the nozzle data line to the greatest extent and will not cause poor contact when it is subjected to external force. At the same time, it can prevent ink from entering the connecting part 2 along the gap between the first connector 22 and the first avoidance groove 31 and between the line body 1 and the second avoidance groove 32, causing a short circuit or data abnormality.

[0036] See also Figure 2 Specifically, the first connector 22 and the second connector 23 are respectively located on opposite sides of the PCB board 21, so as to facilitate the connection between the line body and the nozzle (or board) and the connecting part 2, and avoid the first connector 22 and the second connector 23 being simultaneously arranged on one side of the PCB board 21, resulting in insufficient space or an increase in the volume of the connecting part 2. The first cover body 3a and the second cover body 3b are respectively covered on the side where the first connector 22 and the second connector 23 are located to facilitate the disassembly and assembly of the first connector 22 and the second connector 23, that is, the connector or other components on the PCB board 21 can be disassembled and assembled by simply removing the corresponding cover body. The first avoidance groove 31 is arranged on the first cover body 3a, and the second avoidance groove 32 is arranged on the second cover body 3b.
