Definitions
- the present invention relates to a mechanical connection for printed circuit boards for building up spatial structures from flat printed circuit board waste, the printed circuit boards being connected to one another at a right angle.
- this circuit board waste represents an energetically high-quality, valuable material which should be recycled for other purposes due to its good optical and mechanical properties.
- the aim of the invention is to create a mechanical connection for printed circuit board waste pieces, which makes it possible to assemble the printed circuit board pieces in a simple manner and without additional connecting elements to form spatial structures for any purpose.
- the connection should be as independent as possible of the starting material used, in particular the thickness of the printed circuit boards.
- connection does not require any additional connecting elements, is extremely easy to produce by milling or punching the printed circuit board waste, and is largely independent of the thickness of the respective printed circuit boards, because the curved configuration of the slot in connection with the one behind the outer curve The edge of the snap-in tab edges ensures a secure hold even of thinner printed circuit boards in a wider slot.
- parallelepiped office material containers such as shelves, boxes, disk boxes, archiving boxes and the like can be used. produce.
- EP-A-0 502 281 describes a fastening system for inscription labels for flower pots, an inscription label made of flexible plastic with its arrow-shaped tip being inserted into a slot angled on both sides in the flower pot rim and the arrow edges latching behind the slot edges.
- An expedient embodiment of the invention is characterized in that the web attaches to the middle of the tab in order to be able to latch the tab on both sides.
- the web attaches to one side of the tab, so that the latter only has an edge area which projects beyond the web and is intended for locking only on one side.
- the tab is expediently rounded or tapered in order to enable easy insertion.
- a preferred embodiment of the invention is that the web starts from an edge recess of the circuit board.
- this creates a certain play for movements of the printed circuit board material of the printed circuit board having the slot around the slot and thus the possibility of optimizing the tension of the connection, and on the other hand the tab can be produced more easily in the case of milling: the distance between the locking edges of the tab and The edge of the circuit board from which the tab starts can be varied by positioning a milling cutter with a uniform diameter.
- the slot extends from the edge of the side plate, so that it is open on one side and the tab can be inserted into the slot both vertically and in parallel.
- FIG. 1 shows a slip box for the desk, which is made according to the invention from cut flat printed circuit board waste
- FIG. 2 shows the note box of FIG. 1 in an exploded view
- FIGS. 3a to 3f show different embodiments of the tab and the slot of the plug connection according to the invention
- Fig. 4 shows a cross section through the tab of Fig. 3a, which is inserted into a slot according to Fig. 3f, at the level of the passage through the slot.
- the slip box shown in FIGS. 1 and 2 is composed of five circuit boards 1 which are cut, punched or milled from flat circuit board waste.
- the circuit boards 1 generally have a thickness in the range from 1.5 to 4 mm, although any circuit board waste available on the market can be used in any thickness.
- the printed circuit boards 1 are each connected to one another at a right angle via a mechanical plug connection, each of which consists of a slot 2 and a tab 3.
- the slot 2 has a width which is at least the same, but preferably greater than the thickness of the printed circuit boards 1. By choosing a uniformly wider slot, the slot configuration is largely independent of the thickness of the PCB waste used.
- the slot is curved (FIG. 3f, FIG. 4) or curved in the form of a polygon (FIG. 3d: two-part polygon; FIG. 3e: three-part polygon), so that a curvature outer edge 8 and a curvature inner edge 9 arise (Fig.).
- the associated tab 3 is integrally attached to the edge 5 of the associated other printed circuit board 1 via a web 4 of reduced width, so that the tab 4 has two edge regions 6 which protrude laterally beyond the web 4. It is these edge areas 6 which, in the inserted state of the tab 3, latch behind the outer edge 8 of the slot 2.
- the tab 3 curves during insertion into the slot 2 in accordance with the curvature of the slot 2 until its edge regions 6 have completely passed through the slot 2, the tab 3 springs back into its flat state and the two edges areas 6 reach behind the slot. In the latched position shown in FIG. 4 it can be seen that the tab 3 rests at three points A, B and C in the slot 2.
- connection shown has enough play to ensure that the connection is held securely even with different circuit board thicknesses.
- the tab 3 springs more or less back into its initial position after passing through the slot 2.
- the tab 3 has a protruding edge region 6 on only one side, as is shown in FIG. 3b and in the plug connections of FIGS. 1 and 2.
- the web 4 preferably attaches to the middle of the tab 3, as shown in FIGS. 3a and 3c.
- the slot 2 extend from the edge of the circuit board 1 so that it is open on one side.
- the tab 3 can be inserted both in the direction perpendicular to the printed circuit board 1 having the slot 2 and also parallel to the latter. As a result, nothing changes in the latching function of the single edge region 6 of the tab 3 in this case in cooperation with the curvature of the slot 2.
- the web 4 preferably starts from an edge recess 7 of the printed circuit board 1, as can be seen in particular in the embodiment of the tab from FIG. 3c.
- this enables a certain movement of the material of the other printed circuit board surrounding the slot 2 into this edge recess 7, on the other hand, tabs 3 can be locked under produce different PCB thicknesses simply by attaching a single milling head with a uniform diameter D at a different distance from the edge of the circuit board 1 in order to form the web 4 by milling the tab 3 laterally.
- the tab 3 can have a triangular, trapezoidal or otherwise tapered configuration instead of the rounded shape shown (see FIG. 3a) in order to facilitate insertion into the slot 2.
- the exact shape of the slot is also not critical.
- any spatial structures such as file folders, file trays, boxes, boxes and the like can be used with the aid of the plug connection described. build up.
