CONNECTION APPARATUS AND INTEGRATED ASSEMBLY

A connection apparatus and an integrated assembly. The connection apparatus comprises a base portion (10) and a flow channel portion (20) which are limited and/or fixedly provided. The connection apparatus comprises a plurality of element connection portions and a plurality of external interfaces that can be used for connecting to a system; the base portion (10) comprises at least two accommodating portions; the flow channel portion (20) comprises at least two modules and a connection member (51); the modules are partially located in the accommodating portions; the base portion (10) is provided with a limiting structure that limits the movement of the modules; the base portion (10) is provided with a notch portion at least between two adjacent accommodating portions; the connection apparatus is provided with the connection member (51) that connects at least one group of two adjacent modules; and the connection member (51) is partially located at the notch portion. In this way, components are relatively convenient to process and are then combined, and thus facilitate assembly and use of a system.
