    专利说明:
    [0001] The present invention relates to a mounting device for the spaced mounting of a printed circuit board on an electrically conducting carrier. The mounting device is constructed and arranged so as to form an electrically conducting connection between the printed circuit board and the carrier. [0001] BACKGROUND OF THE INVENTION
    [0002] Mounting devices or connectors are often required, for example, for mounting printed circuit boards in a housing, wherein the printed circuit boards are separated from an electrically conducting or metallic carrier. The mounting devices must be easily attached onto the carrier such that the printed circuit boards can be placed in the desired position with minimal effort and cost. In addition, the mounting devices must be designed such that reliable and easily detachable mechanical and electrical connections can be formed between the printed circuit boards and the carrier. The printed circuit boards, which are often mounted in housings offering little access to the boards, should also be installable and removable as conveniently as possible. [0002]
    [0003] In view of the foregoing, a conventional mounting device having of a spacing sleeve, a screw and a nut is often inadequate in that the spacing sleeve cannot be affixed onto the carrier and thus must be held in place by hand during installation. In addition, sufficient space within a housing or enclosure is usually required in order to screw the nut in a controlled manner as required. [0003]
    [0004] Conventional plastic, dowel-like mounting devices having elastic mounting wings inserted into corresponding recesses of the carrier, thereby fixing the mounting element on the carrier, are also inadequate in that electrically conducting connections cannot be made. The additional use of a screw and nut with these mounting devices is ruled out for the reasons described above. [0004]
    [0005] Thus, there is a need for a printing circuit board mounting device that overcomes the above-mentioned shortcomings of the conventional mounting devices. [0005] SUMMARY OF THE INVENTION
    [0006] The present invention provides a printed circuit board mounting device that can be manipulated easily and reliably, thus rendering possible the convenient mounting of a printed circuit board on a carrier, and also the formation of an electrical connection between the printed circuit board and the carrier. Consequently, the mounting device of the present invention allows swift and easy installation and removal of printed circuit boards within an electronic housing or enclosure. [0006]
    [0007] In accordance with a preferred embodiment of the present invention, the mounting device includes: a spacing element for attaching onto the carrier and for supporting the printed circuit board; and an electrically conducting mounting element coupled to said spacing element for forming a mechanical and electrically conducting connection between the circuit board and the carrier. [0007]
    [0008] In another preferred embodiment of the present invention, the mounting device is characterized in that the spacing element is formed of a plastic or elastic material, and includes a sleeve-type spacing section and a mounting section. [0008]
    [0009] In yet another preferred embodiment of the present invention, the mounting device is characterized in that the mounting section includes a plurality of elastic, finger-type or wing-type mounting members provided for engagement in corresponding recesses of the carrier. [0009]
    [0010] In still another embodiment of the present invention, the mounting device is characterized in that the mounting element includes a screw which, in its tightened position, forms an electrical connection between the printed circuit board and the carrier by means of its head or via a shim at a first end in contact with the printed circuit board and by means of its second, free end in contact with the carrier. [0010]
    [0011] Further in accordance with the present invention, the screw has at its second end a tip which, when tightened, is attached to the carrier or into a bore provided in the carrier. [0011]
    [0012] When the mounting devices according to the invention are used, the carriers are provided with recesses for receiving the mounting members and the printed circuit boards are provided with holes for the screws. Optionally, the carriers are also provided with bores for receiving the tips of the screws, which may, however, be omitted if the carriers are composed of a sufficiently soft material and are formed, for example, by aluminum rails or aluminum profiled sections. In that case, it is possible to screw the tips whose material must of course be harder than aluminum, into the solid material of the carriers. [0012]
    [0013] To mount a printed circuit board, the mounting members are fitted into the recesses. This is easily performed, even in the case of unfavorable installation conditions in a large and unmanageable housing, since the recesses on the carrier can be easily located by touch. The printed circuit board is then placed on the spacing elements, typically four per printed circuit board, and positioned such that the holes in the printed circuit board are aligned with the bores of the spacing element. The screws are then fitted through the holes in the printed circuit board into the bores and tightened. [0013] BRIEF DESCRIPTION OF THE DRAWINGS
    [0014] For a complete understanding of the present invention and the advantages thereof, reference is now made to the following description taken in conjunction with the accompanying Figures in which like reference numerals indicate like features and wherein: [0014]
    [0015] FIG. 1 is a sectional view of a preferred embodiment of a device for mounting a printed circuit board onto a carrier in accordance with the present invention; [0015]
    [0016] FIG. 2 is a bottom view of a carrier in the direction of the arrow II of FIG. 1; [0016]
    [0017] FIG. 3 is a side view of the device of FIG. 1; and [0017]
    [0018] FIG. 4 is a cross-sectional view of the device of FIG. 3 along the line A-A of FIG. 3. [0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
    [0019] FIG. 1 shows a sectional view, in accordance with a preferred embodiment of the present invention, of a connection formed between a carrier [0019] 1 and a printed circuit board 2 by means of a mounting device 3. The mounting device 3 includes a spacing device 4 and a mounting element or screw 5. As shown in FIG. 2, the carrier 1 is preferably a light-metal rail or plate having at least one bore 6 and on either side thereof two slot-like recesses 7. The diameter of the bore 6 is somewhat smaller than the diameter of the threaded part of the screw 5 such that the bore 6 functions like a nut for the screw 5.
    [0020] Preferably, the carrier [0020] 1 is comprised of a sufficiently soft conducting material, such as aluminum, and is sufficiently thin so as to allow the threading of screw 5. The screw 5 can be a so-called “wood” or sheet-metal screw with a suitable thread and a relatively sharp tip, with the diameter of the screw 5 being larger than the diameter of the bore 6. As such, the screw acts to open up the carrier 1 or the bore 6 appropriately when tightened.
    [0021] The spacing element [0021] 4 is constructed of an elastic or plastic material and has, as shown in FIGS. 1 and 3, a sleeve-type spacing section 8 and a plurality of finger-like or wing-like mounting members 9 that are attached to the spacing part and which are provided for engagement in the slot-type recesses 7 of the carrier 1. FIGS. 1 and 3 show, by way of example and not limitation, two mounting members 9. The mounting members 9 preferably have a curved or bent design and are dimensioned such that, when pushed into the recesses 7, the members 9 latch to the carrier 1 under tension. As a result of tensioning, the mounting element 3 is thereby affixed onto the carrier 1.
    [0022] As further shown in FIGS. 3 and 4, the spacing section [0022] 8 has the shape of a cylindrical sleeve which is partly perforated at its wall. The wall in the transverse plane A-A, as shown in FIG. 4, includes the mounting members 9, which are composed of a solid material, and alternating regions of solid material and perforations on both sides of the longitudinal axis 10.
    [0023] The printed circuit board [0023] 2 is mounted on the carrier 1 in such a way that the spacing element 4 is first pressed into the recesses 7 by means of its mounting members 9 and latched into the recesses 7. The printed circuit board 2, which has bores 11 for inserting the screws 5 at the mounting points, is then placed on the spacing element 4 such that the bores 11 of the printed circuit board 2 are positioned above the spacing element 4, and the screw 5 is then pushed from the printed circuit board 2 into the spacing means 4 at each mounting point, optionally using a shim (not shown) and finally tightened. Using this process, the screw 5 is screwed into the bore 6 of the carrier 1, and as a result a mechanically stable and electrically conducting connection is made between the carrier 1 and the printed circuit board 2.
    [0024] Although the present invention has been described in connection with particular embodiments thereof, it is to be understood that various modifications, alterations and adaptions may be made by those skilled in the art without departing from the spirit and scope of the invention. It is intended that the invention be limited only by the appended claims. [0024]
