    CONTEXT OF LTNVENTON
    The present invention generally relates to a rechargeable battery pack for an electro-optical reader, and a method for electrically charging the battery pack and electrically powering the reader with the charged battery pack.
    [0002] Laser-based readers and semiconductor imaging device based readers, also known as scanners, have been used, both in handheld and / or handheld modes of operation. or hands-free, for electro-optically reading target symbols, such as one-dimensional and / or two-dimensional bar code symbols, to be decoded, as well as target documents, such as forms, labels, receipts, prescriptions, driving licenses, identification badges, payment / loyalty cards, and the like, an image of which must be formed. In hands-free mode, the reader is stationary, and is generally mounted and accommodated in a docking station, such as a stand or stand, mounted on a work surface or a similar support surface. A user typically presents a target to a fixed drive window in a presentation mode. In the hand-held mode, the reader can be moved, and the user usually lifts the player from the docking station, holds the reader in his hand, directs the player to the target, and manually triggers a trigger to initiate the reading.
    [0003] A large number of these readers are cordless and, when a reader is removed from its docking station, an on-board rechargeable battery pack is required to provide electrical power for operation, and must be recharged periodically. . The docking station generally includes a station contact block on which stationary electrical contacts are generally supported for recharging the battery pack when the player is placed in the docking station, as well as additional station electrical contacts generally. used to exchange electrical signals. for example, data and control signals, with the player via the battery pack when the reader is placed in the docking station. Likewise, the reader generally includes a reader contact block on which a pair of drive electrical contacts are generally supported to provide the battery bioc power to the reader, as well as additional drive electrical contacts generally used to exchange data. electrical signals, for example, data and control signals, with the reader via the battery pack. The reader contacts and the station contacts are integrated in their respective contact blocks consisting of, for example, a plastic material, and the reader contacts and the station contacts are exposed on a part of the respective contact block.
    Although the known battery pack is generally satisfactory for its intended use of making electro-mechanical connections with the reader contact block in the reader and with the station contact block in the docking station, the Known battery pack has proved to be relatively complex as to its design and assembly. For example, the known battery pack is generally provided with a pair of contact blocks for respectively being coupled with the reader contact block and with the station contact block. The pair of battery pack contact blocks are mounted on a pair of printed circuit boards (PCBs), which must be separately installed and properly aligned each in the battery pack. Each battery pack contact block itself represents a relatively expensive component to manufacture and install, which increases the complexity and cost of the battery pack as a whole.
    Therefore, there is a need to make a battery pack for a less complex and less expensive electro-optical drive, without sacrificing the performance of the battery pack over its lifetime.

    DETAILED DESCRIPTON OF LINVENTON
    An aspect of the present invention relates to a rechargeable battery pack for electrically powering an electro-optical reader, either a laser-based or an image-forming device, when the battery pack is mounted in the battery. reader in a mounting position. The battery pack includes a battery housing, a rechargeable battery supported by the battery housing, a printed circuit board (PCB) supported by the battery housing, and first and second electrical connectors, both supported by the same PCB. ef / or by the battery slot and both functionally connected to the battery. The first electrical connector has a first plurality of electrical contacts connected to the reader in the mounting position. The second electrical connector has a second plurality of electrical contacts connected to a source of electrical power for electrically charging the battery pack.
    [0018] Advantageously, the first plurality of electrical contacts are exposed outside the battery housing and are in electromechanical contact with a corresponding plurality of reader contacts, preferably supported on a reader contact block, in the reader in the mounting position. The second plurality of electrical contacts are likewise exposed outside the battery housing and are either in electromechanical contact with a corresponding plurality of station contacts, preferably supported on a station contact block, in a docking station in which the reader is mounted in a home position, or connected directly to the power source by a charging cable. At least one of the electrical connectors, or both, may be a contact block mounted on the PCB. At least one of the electrical connectors, or both, may be a set of electrically conductive surface pads on the PCB. At least one of the electrical connectors, or both, are a set of electrically conductive terminals mounted on the battery housing. Preferably, the terminals are molded into the battery housing. At least one or both of the electrical connectors or an additional connector may be USB (universal serial bus) connectors, preferably of the micro-USB type, for connection to the charging cable. Any combination of contact blocks, surface pads, molded terminals, and USB connectors can be used with the battery pack.
    Another aspect of the present invention relates to a method for electrically charging a battery pack and electrically powering an electro-optical drive with the charged battery pack. The method is performed by mounting a rechargeable battery and a printed circuit board (PCB) in a battery slot of the battery pack, mounting the battery pack in the reader in a mounting position, supporting a first electrical connector and a second electrical connector by at least one of the same PCB and the battery housing, by connecting the first and second electrical connectors to the battery, connecting a first plurality of electrical contacts of the first electrical connector to the reader in the position of mounting, and connecting a second plurality of electrical contacts of the second electrical connector to a source of electrical power for electrically charging the battery pack.
    Thus, it is no longer necessary to provide and install two PCBs, or two blocks of contacts, in the battery pack. The battery pack is thus less complex and less expensive than before, and the performance of the battery pack is not sacrificed over its lifetime.
    With reference now to Figure 1 of the drawings, the reference numeral 30 generally identifies a cordless electro-optical reader, either laser-based or image-forming device, which is ergonomically configured. advantageously as a gun-shaped housing having a barrel or body 32 and a lower handle 38 extending rearwardly from the body 32. A window 36 is located adjacent to a front portion or nose of the body 32. The The reader 30 is either held by the handle 38 in the hand of an operator and used in a handheld mode, as described above, in which a trigger 34 is manually depressed to initiate reading of symbol / document targets. in a range of working distances from the window 36, and / or is mounted in a presentation support or docking station 10 and used in a hands-free mode in which symbols / C targets cuments are presented in a range of working distances from window 36 for reading. A cable 12 is connected to the station 10 to deliver electrical energy from a source of electrical power to the station 10 and, in turn, to the reader 30, as well as to support bidirectional communications between the reader 30 placed in the docking station and a remote host (not shown) via station 10.
    As best seen in Figure 2, a battery pack 20 is preferably inserted in the direction of the arrow A into an open lower end of the handle 38 and is mounted therein in a mounting position. The battery pack 20 is secured in the mounting position by a threaded fastener 54 which extends through an extension of the handle 38 and threadingly engages with a threaded bore in the handle 38. The battery pack 20 can be removed from the handle 38 by unscrewing the attachment member 54 and moving the battery pack in the direction opposite to the arrow A. The battery pack could be mounted in the housing in various ways. For example, the rear side of the handle 38 could be opened, and the battery pack could be inserted through the open back side of the handle, or could be hooked to the handle and pivoted forward through the back side open. As another example, the battery pack need not be mounted inside the handle, but may be the handle itself and be connected to the upper barrel 32 to form the gun-shaped housing. As best seen in Fig. 5, the battery pack 20 includes a rechargeable battery 22 and a printed circuit board (PCB) 24, both supported by a battery housing having housing shell portions 26, 28 which define an inner portion in which the battery 22 is mounted. The battery housing 26, 28 is elongated and extends lengthwise between opposite front and rear end regions along a longitudinal axis (arrow A).
    The battery pack 20 also includes a first electrical connector 40 and a second electrical connector 42 located at opposite end regions of the battery housing 26, 28. As described below, the first electrical connector 40 is supported either by the PCB 24 and / or by the battery housing 26, 28 and is operably connected to the battery 22, and the second electrical connector 42 is likewise supported either by the same PCB 24 and / or by the battery housing 26, 28 and is operably connected to the battery 22. The first electrical connector 40 has a first plurality of electrical contacts, and the second electrical connector 42 likewise has a second plurality of electrical contacts, all contacts being exposed outside the housing. battery 26, 28.
    When the battery pack 20 is inserted into, or integrated with, the reader 30 in the mounting position, the battery pack 20 can supply electrical power to the electrical components in the reader 30 when the reader is in the operating mode held in hand. The electromechanical contact between the first connector 40 and the reader 30 is made by a reader contact block 44 (see FIG. 2) mounted on a PCB in the reader 30. The reader contact block 44 supports a plurality of drive contacts, which couple with the first plurality of electrical contacts of the first connector 40 in the mounting position.
    When the battery pack 20 is to be recharged, the reader 30, with the battery pack 20 installed, can be advantageously mounted in the docking station 10 in a home position. The electromechanical contact between the second connector 42 and the station 10 is made by a station contact block 14 (see FIG. 4) mounted on a PCB in the station 10. The station contact block 14 supports a plurality of station contacts, which couple with the second plurality of electrical contacts of the second connector 42 in the home position. As described below, charging does not need to be performed in station 10.
    The electrical connectors 40, 42 can take various forms. For example, one of the electrical connectors 40, 42, or both may be a contact block, such as the contact block identified by the number 42 in FIGS. 2, 3 and 5 and mounted on the bottom of the PCB. 24. The contact block 42 supports the respective plurality of electrical contacts of at least one of the electrical connectors 42, 44. As another example, one or both of the electrical connectors 40, 42 may be , as shown in FIG. 3, on the top of the PCB 24, a set of electrically conductive tracks or surface pads 46A-E on the PCB 24. The pellets 46A-E are the tracks left after a sheet of copper laminated on PCB 24 has been etched. The pads 46A-E constitute the respective plurality of electrical contacts of at least one of the electrical connectors 42, 44. As yet another example, a USB (universal serial bus) connector 52, preferably a micro-connector USB, can be mounted on the same side, or, as shown, on the opposite side, of the PCB 28. The USB connector 52 is connected by a USB cable 56 to a power source 58 to electrically charge the block of 20. The USB connector 52 may replace one of the electrical connectors 40, 42, or may be provided as an additional connector. Thus, as described heretofore, the connectors 40, 42 may both be contact blocks, or both may be surface pads, or may be one of each, or may be supplemented, or replaced, by the USB connector 52, as illustrated in Figures 2, 3 and 5.
    As a further example, one of the electrical connectors 40, 42, or both may be a set of electrically conductive terminals 48A-E (see FIGS. 6 and 8) mounted on the battery housing 26, 28. As shown in FIGS. 6 to 8, in a construction variant, the battery pack 20 again includes the rechargeable battery 22 and the PCB 24, both supported by the battery housing including the housing shell portions 26. , 28 which delimit an inner portion in which the battery 22 is mounted. The above-mentioned terminals 48A-E are electrically conductive metal strips that are molded into the battery housing 26, 28, rather than being mounted on the PCB 24, to increase the resistance of the electromechanical connection. The terminals 48A-E constitute the respective plurality of electrical contacts of at least one of the electrical connectors 40, 42. As also shown in FIGS. 6 to 8, the first connector 40 may be a contact block mounted on the PCB. 24. A cutout 50 in the housing portion 26 receives the contact block 40.
