Definitions
- the invention relates to a printing material container for interchangeable mounting and use on a printer having a plurality of printer-side terminals, comprising: a circuit board having at least one circuit capable of interacting with a printer side circuit, the circuit board having a surface facing the terminals; Edge, a plurality of contacts with a contactable contact field, which are connected to the at least one circuit and arranged for contacting by the printer-side terminals, wherein the contact pads of one or more of the plurality of contacts on the surface of the board are arranged.
- the invention also relates to a circuit board for mounting to a printing material container for interchangeable mounting and use on a printer having a plurality of printer-side terminals, comprising: at least one circuit capable of interacting with a printer-side circuit, the circuit board providing one of the terminals of the printer A printer-facing surface and an edge, a plurality of contacts with a contactable contact pad, which are connected to the at least one circuit and arranged for contacting by the printer-side terminals, wherein the contact pads of one or more of the plurality of contacts arranged on the surface of the board are.
- Ink cartridges for printers are often equipped with printed circuit boards, especially a memory chip, attached to or attached to the cartridge case.
- the ink cartridge has an ink filled housing.
- a printed circuit board (chip / memory chip) is attached. This has contact fields, which are contacted in printer inserted in the printer, while operating the printer from the printer-side mating contacts to exchange data, to ensure the power supply of the chip, etc.
- specific data can be stored, such as the level.
- the PCB can perform certain logic functions.
- the circuit board has contacts with device-side terminals (e.g., pins) aligned contact pads which are contacted by the device / printer ports during operation of the printer to make electrical connection.
- device-side terminals e.g., pins
- the problem is the contacting of the contacts of the board through the terminals of the device after insertion of the cartridge or cartridge into the printer, or after the start of the operation of the printer. This is due to the presence of material such as ink or toner inside the printer, as it can not be completely avoided that this material is unintentionally distributed inside the printer and deposited in different places. Thus, after a long-term operation of the printer or due to a malfunction, the material can also reach the area of the printed circuit board and be deposited there.
- the object of the present invention is to provide a printing material container with a circuit board and a circuit board, which allow a secure contact, in particular the decisive for the function of the printer contacts the board.
- the contact field thus extends from the surface of the board over the outer edge or an edge of an opening provided in the board or recess, in the region of the outer edge or the inner wall of the opening of the board.
- the metallization (i.e., the contact field) of at least one contact thus either extends exclusively on the edge sloping to the main surface, or partially in addition on the surface, i. the contact pad has an area disposed on the surface and a portion disposed on the edge of the board.
- a contact can take place along the outer edge (or the inside of the opening) of the board.
- the terminals of the printer By inserting the terminals of the printer in an opening or laterally along the outer edge of the board secure contact can be made. Not only can the terminals be moved perpendicularly to a contact surface, as in conventional chips having top contact pads, but the contacts have at least one component of movement aligned along the contact pad (i.e., contact pad) in the region of the oblique contact surface. The contacts can thus grind along the contact and remove any impurities there.
- the container may include an ink cartridge, a toner cartridge or the like.
- board in the sense of the invention comprises a semiconductor plate, a chip, a printed circuit board or the like. Components.
- oblique is to be understood in the sense that the surface of the oblique (part of) the contact field deviates from the (relatively) horizontal surface of the board. With respect to the normal vectors of the oblique part of the contact field and the surface, this means that their directions deviate from each other at the same angle as the surfaces. In particular, the surfaces (or normal vectors) enclose an angle of approximately 90 °, particularly preferably an angle between 75 ° and 90 °. 90 ° means that the inclined part of the contact surface is (substantially) perpendicular to the contact fields which are arranged on the surface of the chip.
- the at least one contact field thus extends from the surface of the board over the outer edge in the region of the outer edge of the board.
- the subregions of the contact field merge into one another and are electrically connected to one another.
- the obliquely arranged contact field can also be located exclusively on the outer edge of the chip. In this way, a contact also statfinden on the outer edge of the board. Since the contact travels along the outer edge of the board during the contacting, any contamination or wetting of the surface is removed before the printer is used. The electrical contact is thereby improved.
- the goal is to make the contact fields so large that the terminals of the printer, the fields within the tolerance of the position of the fields, in any case with certainty.
- the obliquely arranged part of the at least one contact field is inclined at an angle between 75 ° and 90 °, in particular at an angle between 85 ° and 90 °, with respect to the surface of the board.
- the board has at least one opening which is arranged in the contact field or adjacent to one of the contact fields.
- the opening may be a recess or, in particular, a through hole extending through the board.
- the obliquely arranged part of the at least one contact field is arranged in at least one region of the inner wall of the opening.
- This has an inner wall portion which extends obliquely or perpendicular to the board surface.
- the inner wall region of the opening is at least partially metallized there, i. it forms part of the contact field where the terminals of the printer are to contact the contact.
- the obliquely arranged part of the at least one contact pad is arranged on the outer edge of the board.
- the printmaker includes a first group of contacts and a second group of contacts, wherein the first group is operable with a first electrical voltage and the second group is operable with a second electrical voltage, the first voltage being higher than the second voltage ,
- Each group or category of contacts consists of one or more contacts.
- the groups may differ functionally.
- the first group of contacts are used for supply with higher voltage and, for example, participate in a level measurement.
- the second group can cooperate with a circuit or logic circuit or with a data storage or be connected and participate in the exchange of data between the printer and the printing material container.
- the contacts of the first group of contacts may include a contact pad at least partially disposed obliquely to the surface of the board.
- the contacts of the first group of contacts may, in particular, have a contact field, which is arranged at least partially on the outer edge of the board.
- the print cartridge dispenser may include a third group of contacts that are essentially passive ports.
- the third group contact (s) may help to detect a voltage applied to it or to it (whether through a circuit in the board or in the printer), for example in the event of a malfunction.
- the one or more contacts of the second and / or third group of contacts may include a contact pad at least partially disposed obliquely to the surface of the board.
- the one or more contacts of the second and / or third group of contacts may include a contact pad at least partially disposed in at least a portion of the inner wall of an opening of the board.
- the obliquely arranged part of the at least one contact field can be inclined at an angle between 75 ° and 90 °, in particular at an angle between 85 ° and 90 °, with respect to the surface of the board.
- the circuit board can have at least one opening which is arranged in the contact field or adjacent to one of the contact fields.
- the obliquely arranged part of the at least one contact pad is preferably arranged in at least one area of the inner wall of the opening and / or on the outer edge of the board.
- Toner cartridges are often provided with printed circuit boards, in particular with a memory chip, which is attached or attached to the cartridge housing.
- FIG. 1 shows an embodiment of a toner cartridge 1 with a housing 10 and a housing 10 arranged on the developing roller 11 which is driven by a drive wheel 12.
- the toner cartridge 1 has a chip 2 (memory chip, circuit board, board), which is arranged on the rear side of the housing 10 relative to the insertion direction, in this case.
- data specific to the toner cartridge 1 can be stored, e.g. the level.
- the circuit board 2 can perform certain logic functions.
- the circuit board 20 has, as in the FIG. 2 schematically illustrated, to the device-side contacts aligned contact surfaces K1, K2, K3, K4, K5, K6, K7, K8, K9, which are contacted during operation of the printer from the contacts of the printer to make an electrical connection.
- the invention relates primarily to the arrangement and design of the contact fields K1, K2, K3, K4, K5, K6, K7, K8, K9 of the circuit board, for example, as in the FIG. 2 can be arranged or formed represented.
- the contact fields K1 and K2 form a first category of contact surfaces which are operated at a higher voltage than the data contacts K3, K4, K5, K6, K7.
- the contact surfaces K8, K9 form a third contact field category, namely, for example, short-circuit detection contacts, while the remaining contacts can be data transfer contacts.
- the contact fields K1 and K2 are arranged adjacent to the edge of the board.
- the edge is arranged obliquely relative to the upper or lower edges of the chip (angle about 45 ° +/- 30 °, in particular 45 ° +/- 15 °).
- the contact fields K1 'and K2' are oriented perpendicular or obliquely relative to the surface of the contact fields K1-K9. So they point in a different direction than the contact fields K1-K9.
- it is precisely the contacts K1, K2 which are operated at a higher voltage that are also supplied or operated laterally via the contact fields K1 'or K2'.
- Adjacent to the contacts K8, K9 of the third category or in the contact field area engagement openings O1, 02 are formed in the board. These are at least partially coated inside conductive (eg metallized) and electrically connected to the contact fields K8 and K9.
- a contact pin of the printer can engage in the openings O1 or 02 and thus establish a secure contact, in particular during vibration during the printing operation.
- FIG. 4 Another embodiment is in the FIG. 4 shown.
- the contacts K1 and K2 in turn have oblique or perpendicular to the contact fields K1 and K2 arranged contact fields K1 'and K2' on.
- the contact points KP can be arranged on the chip surface, or, as in the case of the contacts K1 / K1 ', K2 / K2' on the side edge of the board 22.
- the contact point can be arranged within the metallized opening O1 ,
- the contact point KP is not on the chip surface, but at the side edge or within the opening O1 at the inner wall.
- the printer-side contacts eg contact pins
- the printer-side contact which corresponds to the contact field K8, engages in the opening OV1 and abuts against its inner wall.
- a conductor L extending from the contact K6 or connected to this contact surface K6 can be arranged. If e.g. the contact K6 is a third category contact, e.g. a short-circuit detection contact, it is ensured by the conductor L that a occurring between the contacts K1 and K8 short circuit is detected quickly and reliably by the contact K6.
- the contact K6 is a third category contact, e.g. a short-circuit detection contact, it is ensured by the conductor L that a occurring between the contacts K1 and K8 short circuit is detected quickly and reliably by the contact K6.
- FIGS. 5 and 6 show similar embodiments of a board 23 and 24 as in the FIG. 4 shown board 22.
- the same elements are provided with the same reference numerals.
- both the contact K6 and the contact K7 each have a conductor L, which is connected to the respective contact K6 or K7 and extends between the contacts K1 and K8 or K2 and K9.
- the contacts K6 and K7 belong to a category of the short-circuit detection contacts, in this case a short circuit occurring between the contacts K1 and K8 or K2 and K9 can be detected quickly and reliably by the contact K6 or K7.
- FIGS. 7 and 8 Other embodiments of boards 25 and 26 are in the following FIGS. 7 and 8 shown. These correspond essentially to the previously described embodiments. The same elements are provided with the same reference numerals.
- Possible contact points KP between the printer-side contacts (for example contact pins) and the contact fields K1, ..., K9 are also marked here as points.
- FIGS. 9 and 10 show embodiments of boards 27 and 28, in particular, the contact fields K1 / K1 'and K2 / K2' as described above.
- Like reference numerals refer to corresponding components already described.
- FIGS. 4 to 10 Only the externally exposed, ie contactable, contact surfaces and interconnects are shown. Further (not visible) intermediate lines between the contacts or additional metallizations are not exposed to the outside, but are covered by a non-conductive layer (eg paint). In this way, the susceptibility of the chip is reduced, for example, by contamination of the metallizations.
- a non-conductive layer eg paint
- the FIG. 11 shows a section AA FIG. 10 ,
- the board 20 or its basic body (made of plastic) has an outer edge over which the contact field K2 extends in the form of a contact field section K2 'of the contact field K2.
- a printer-side contact pin 3 contacts the contact K2 at a contact point 30 which is arranged along the outer edge K2 'of the contact K2. Since the contact pin 3 approaches obliquely, a secure contact 30 is made even with contamination of the contact field K2.
