GE Quick Connect and Seal V2

Updated V1 to incorporate a stainless steel clip which secures and compresses the block. Faster assembly achieved as no curing time delay. . Attaching the Block parts together is achieved by the use of off the shelf Bathroom Silicone sealant, readily available and a low cost alternative to high tech adhesives. As the clip compresses the O-Ring groove part to the main block, the curing of the silicone can happen after assembly. . I believe that if the parts are presented correctly at a workstation this assembly could be completed in less than 60 seconds. . Refer to the previously uploaded V1 for details of the seal. GE Quick Connect and Seal V1 . All molded parts can be used without post mold machining. Draft angles and avoidance of apertures simplifies the mold design and ejection of parts . The Stainless clip could incorporate a GE logo and message. This reduces the overall material used. As the clip is in tension the cross section does not need the full length of 600mm. . In contrast the curved spring section at the front and the hooked edge at the rear use the full 600mm length to combat the bending forces resulting from the 3 bar water pressure on the area of the block. . The force is substantial on the area of 0.492 x 0.042 = 0.0212 m2 at 3 bar = 6.347 kN = 647 kg/f. The moment of inertia of the clips is 6.25 x 10E-12 m4 (0.6 wide x 0.0005 high) - 300mm x 0.5mm by two. . Youngs modulus for 301 Austenitic SS Strip = 193,000 Mpa . Using a fixed cantilever formula as a simple method of checking the deflection of the clip ends. . For the cantilever of 5mm at the front of the clip the deflection is 0.25mm For the cantilever of 2mm at the clip hook the deflection is 0.015mm . This is an acceptable deflection at the maximum force and the combined movement of 0.265mm of the block in the cavity will not exceed the tolerance of the O-Ring. . This part could be made from spring steel and electroplated depending on the required volumes. The design adheres to overall dimensions specified and this assembly can be dismantled if required by un-hooking the clips.
