Zusammenfassung:A diaphragm pump and method for making same, the pump having a diaphragm coupled to a wobble plate achieved using: a post ( 11 ) protruding from the wobble plate toward the diaphragm and at least partially surrounded by a collar ( 11 a); and a pin ( 22 ) protruding from the diaphragm toward the wobble plate and having a recess ( 22 a) for mating with the post ( 11 ) and also having an outer portion ( 22 b) surrounding the recess ( 22 a) and able to resiliently deform so as to squeeze through the collar ( 11 a) when the pin ( 22 ) is pushed onto the post ( 11 ). The outer portion ( 22 b) of the pin typically includes a locking feature ( 22 c) for holding the pin ( 22 ) on the post ( 11 ). The pin ( 22 ) and the diaphragm are typically made from thermoplastic materials, with the pin ( 22 ) typically made from a harder material than the diaphragm.
