  • a valve block 10, a circuit board 12 and a keeper 14 are the three main components of a valve block assembly for a fluid manifold.
  • the valve block 10 has standard valve ports and can mount one or two solenoid central valves in a conventional fashion.
  • the ports and solenoid central valves are not fully shown for simplicity of the drawings. Such ports and valves can be seen in U.S. Patent 6,053,198 which is incorporated by reference for this purpose.
  • the valve block 10 has a circuit board receiving aperture 16 therethrough.
  • the aperture 16 has two opposing longitudinal slots 18 and 20 therein sized to receive the circuit board 12.
  • the top slot 20 receives the top edge 19 which has a stop flange 21 at one end that abuts a shoulder 23 in slot 20.
  • the bottom slot 18 has a raised center protrusion 22 to engage a recess 24 at the bottom edge 26 of the circuit board.
  • the leading portion 28 of the bottom edge 26 is canted to engage the leading edge 30 of the protrusion.
  • the protrusion may have its leading edge 30 canted. In this fashion, circuit board 12 enters side 17 to engage within aperture 16.
  • the circuit board 12 has a horizontally extending slot 32 substantially extending most of the width of the board 12 to allow the bottom edge section 26 to be resiliently flexible upwardly to ride over the protrusion 22.
  • the bottom edge 26 is normally biased downward to a rest position as shown in Figure 1 once it clears the protrusion 22 to axially lock the circuit board 12 relative to the valve block 10.
  • the bottom edge section 26 below slot 32 at each end of recess 24 can also be referred to as a tang or prong.
  • the circuit board 12 is releasable from the aperture 16 by lifting the front edge 28 to clear the recess 24 from the protrusion 22 and backing out the circuit board 12 from the slots 18 and 20.
  • the keeper 14 as shown in detail in Figures 2, 3, and 4 is used to permanently mount and affix the circuit board within aperture 16. Once the circuit board is in the position shown in Figure 1, the keeper slides into aperture 16 from opposite side 19 and into slot 32 until it snap fits into position and locks the circuit board permanently into position.
  • the keeper 14 has a central slot 34 that receives a circuit board edge 36 defining the upper edge of slot 32.
  • the keeper has higher side walls 35 with a height to completely hide the slot 32 and a center thickness at slot 32 that fills slot 32 and prevents the lower edge section 26 from lifting. Thus the edge section 16 cannot disengage the recess 24 from the protrusion 22 and the circuit board 12 becomes locked in position.
  • the slot 32 has a transverse extending notch 40.
  • a tongue 42 of the keeper snap fits into this transverse notch 40.
  • the tongue 42 extends along the slot 34 and is resiliently flexible but is biased to an upper rest position.
  • the mounting end of the tongue is near the leading edge 45 of keeper 14 and the distal end of the tongue extends toward the trailing end 46.
  • the distal end has a transverse upwardly extending tab 44.
  • Either the tab 44 or the upper edge 36 has a canted forward section to allow the tongue to flex downward and ride along edge 36 until the tongue tab 44 pops into the notch 40.
  • the notch and tab are shaped along respective edges to prevent the tongue from being forced or moved downwardly when exiting horizontal force is exerted onto the keeper.
  • the high side walls 35 laterally retain the keeper 14 aligned with edge 36 at the slot 32 and prevent access to the tongue 42 or the tab 44 from the sides.
  • the keeper has trailing end wall 46 that conceals slot 36 and prevents tampering by eliminating straight access to the tab 44. In this manner, the tongue 42 and tab 44 are totally concealed and are not accessible.
  • the circuit board and keeper assembly is permanently affixed in place in the valve block.
  • a second embodiment is shown where the keeper 114 has tongue 144 with notch 140 therein.
  • the slot 132 in circuit board 112 has tab 144 above the recess 124. While tab 144 is shown protruding upward and the notch is shown facing downwardly, these directions may be reversed.
  • the function of the keeper 114 operates the same as in the first embodiment.
  • the circuit board 112 and keeper enter opposite sides 17 and 19 of aperture 16 of valve block 10 and connect together to permanently lock the circuit board 112 to the valve block 10.
  • FIG. 8 a third embodiment is shown where the circuit board 212 has a downwardly facing slot 218 and the edge or rail 221 is shown on the bottom of the aperture 216 of the valve block 210.
  • the slot 218 and edge 221 similarly have complementary protrusion 222 and recess 224 to axially affix the circuit board in place.
  • the slot 218 on the circuit board is raised to disengage the rail 221 by lifting which is accomplished by the existence of the slot 232 extending along the circuit board.
  • the keeper 14 is structured the same as the keeper 14 shown and described for the first embodiment and engages notch 240 to lock the circuit board 212 permanently into aperture 216.
  • FIG. 9 illustrates a fourth embodiment where the circuit board 312 fits into a valve block 10 which is structured the same as shown in the first embodiment.
  • the circuit board 312 has two pairs of opposing rails 346 with a slot 350 between each pair. Each rail 346 is separated from an opposing rail by slot 332.
  • a resiliently flexible tongue 342 extends from the circuit board along one slot 350.
  • the keeper 314 has a center slot 334 to lift and receive the tongue.
  • a hole 340 is in slot 324 to receive a tab 344 at the distal end of the tongue when the keeper is moved into place.
  • valve block 410 as shown in Figure 10 is made from plastic or other resilient material, the flexible prong 460 can be incorporated into the valve block 410 rather then the circuit board 412.
  • the circuit board has a bottom edge 426 that engages in the valve block aperture 416 surface as described in any of the previous embodiments.
  • the circuit board 412 shown in Figure 10 has its bottom edge 426 with a protrusion 422 that engages prong 460.
  • Prong 460 has a recess 424 in its center slot 418.
  • Slot 432 is under the slot 418 to allow prong 460 to be flexibly movable downward to allow the slot 418 to lower from its rest position which in turn allows the circuit board to disengage and slide in or out. Once the circuit board 412 is engaged, a keeper 414 slides into slot 432 to prevent the prong 460 from lowering.
  • the prong 460 remains in locked engagement with the circuit board.
  • the keeper 414 has a flexible tongue 442 which has distal tab 444 that engages a hole 440 in the valve block. Once engaged, the rest of keeper 414 conceals the tongue 442, tab 444 and hole 440 to provide a permanent locked position of the keeper, circuit board and valve block.
