Utility model content
Under this background, propose a kind of for circuit board being arranged on to the mechanism on device, described mechanism has at least one and is arranged in the bolt on described device, on the outer wall of described bolt, arrange at least one cutting rib, wherein said at least one bolt be configured to import to described circuit board at least one hold in opening.
By described method, circuit board can be arranged on to device, generally be in the framework in technical equipment, circuit board to be aimed at device.Use and be arranged in the bolt on device for this reason, described bolt also can be called alignment pin or apotting spindle, and have cutting rib (so-called " Crash Ribs "), described cutting rib (Schneidrippe) is extruded to holding in opening of circuit board at cutting rib and/or while holding the inner wall deformation of opening.
By means of described cutting rib, can dwindle when mounted the tolerance series between circuit board and device.Correspondingly, by plastics or metal bolt, via cutting rib self-cutting, enter into when mounted the opening that holds of the circuit board that can be made by fiber strengthened plastics.The aligning of circuit board and pre-centering thus are addedly realized by the importing inclined-plane of the regulation on bolt.
Other advantages of the present utility model and design are provided by specification and accompanying drawing.
Self-evident, feature noted earlier and that will set forth below not only can be used and can in the combination at other, use or can use individually in corresponding indicated combination, and does not leave protection range of the present utility model.
Accompanying drawing explanation
Fig. 1 a shows the schematic diagram of a kind of embodiment of described device;
Fig. 1 b shows the amplification diagram of the first bolt;
Fig. 1 c shows the amplification diagram of the second bolt;
Fig. 2 a and 2b schematically show other detail perspective view of the second bolt.
By means of execution mode, schematically show in the accompanying drawings the utility model and with reference to the accompanying drawings the utility model be described in detail.
Accompanying drawing is carried out to associated and whole description, and identical Reference numeral represents identical assembly.
Embodiment
Fig. 1 a shows the schematic diagram of the embodiment of device 2, and described device is configured to the housing shell of housing of the control electronics of control technology device, for example motor vehicle at this.In the region at the angle 8,10 at the wall shown in this of described device 2, be furnished with the first bolt 4 and the second bolt 6 on the surface of described wall, described bolt is configured to the assembly of described mechanism and illustrates enlargedly in Fig. 1 b and 1c.The details of the second bolt 6 is schematically illustrated by other perspective view in Fig. 2 a and 2b.
In addition Fig. 1 a illustrates, and arranges that a plurality of reinforcements, three pass through module 12 and a plurality of screws accommodation section 14 for lining on the surface of the wall of described device.Device 2 in addition by around wall 16 limit.
For being had at least one, at least one bolt 4,6 that is arranged on the mechanism on described device 2 at this unshowned circuit board is arranged in the cutting rib 18,20 on its outer wall.Described at least one bolt 4,6 be configured to import to circuit board at least one hold in opening, wherein said at least one hold open construction for being sleeved on described at least one bolt.Can arranging electronic module and/or switching circuit on described circuit board.
At least one is such holds opening and also can be arranged in equally in the region at angle of circuit board.A plurality of bolts 4,6 have and that on circuit board, in order to hold bolt 4,6, arrange, circular hold opening, are generally the spatial distributions that accommodation hole is identical on device 2 surface.Conventionally described in, hold open construction for the hole through circuit board.
At at least one cutting rib 18,20 described in design, by the material harder than circuit board, made.Common described at least one cutting rib 18,20 is shaped on the outer wall of described at least one bolt 4,6 and by the material structure identical with described at least one bolt 4,6, described bolt is made by the material identical with device 2 at this.
On the outer wall of bolt 4,6 shown here, correspondingly arrange three cutting ribs 18,20, described cutting rib is spaced from each other with the angle of 120 °.If bolt 4,6 is correspondingly imported to the holding in opening in it of attaching troops to a unit while installing, in in this case three cutting rib 18,20 arrival equipment, hold on the inwall of opening, wherein said three cutting ribs 18,20 are in equipment on three contact points on inwall, and wherein said inwall is plastically out of shape by cutting rib 18,20 on these contact points.In described three contact points execution mode shown here in same plane.
In other design, on the outer wall of at least one bolt 4,6, can arrange a plurality of, n cutting rib 18,20 namely, described cutting rib is spaced from each other and is distributed on outer wall symmetrically thus with the angle of (360/n) °.
Fig. 2 a illustrates, the top 22 of at least one bolt 4,6 on outer wall, be shaped at least partly section ground taper and frustum-like shape construct, thereby make top 22 also can be called importing inclined-plane.Also possibly, construct on 22 tapers ground, top and coming to a point gradually subsequently.By the top 22 of described at least one bolt 4,6 or this shape of upper segment can make by circuit board hold opening sleeve be contained in attach troops to a unit easier on the bolt 4,6 of described circuit board.
In addition Fig. 2 a illustrates, and described at least one cutting rib 18,20 is arranged in below top 22.Described in the outer radius maximum of the outer wall of general described at least one bolt 4,6 below top 22 is less than conventionally, at least one holds the inside radius of the inwall of opening.At at least one, be arranged in the region of the cutting rib 18,20 on the outer wall of at least one bolt 4,6, the outer radius of outer wall be greater than described at least one hold the inside radius of the inwall of opening.
