It is an integral part of the software architecture, which realizes the link between the compo通过建模、交互规则s between the components. Unlike components, connectors do not need to be compiled.

Definition: The connector is the realization of component operation, it is a six-tuple . Where ID is the identification of the connector. Role is the set of interaction points between connectors and components, Role=. Where ID is the identification of Role; Action is a collection of Role activities, each activity is composed of time links (predicates); Event is a collection of events generated by Role; LConstrains is a set of constraints on Role. The purpose of separating Role from the other attributes of the connector is to highlight the polymorphism of the connector, that is, a connector can be connected to multiple components at the same time.

Beha is a collection of behaviors of connectors.

Msgs is a collection of messages generated by events in each Role in the connector.

Cons is a collection of connector constraints, which includes the initial conditions, pre-conditions and post-conditions of the connectors. Sometimes in order to clearly express these three conditions, it can be written as Cons(init, pre-cond, post-cond), init, pre-cond and post-cond represent the set of initial conditions, pre-conditions and post-conditions respectively.

Non-Func is the non-functional description of the connector, including the safety and reliability description of the connector, etc.

Stainless steel reinforcement connector structure:

It is composed of two steel wire heads with the same specifications and with right-hand threads, and a connecting sleeve with right-hand internal threads. One of the two steel bars is a standard steel wire end with an effective thread length of 1/2 the length of the connecting sleeve; the other is a standard steel wire end with an effective thread length of the connecting sleeve length plus a long wire rebar; the connecting sleeve is a standard connecting sleeve cylinder.
