Normally open and normally closed connecting rod

When discussing "normally open and normally closed connecting rods", the first thing to be clear is that the concepts of normally open and normally closed are usually used to describe the state of electrical contacts or switches, rather than directly used to describe connecting rods. However, in some mechanical or electrical systems, connecting rods may be combined with components with normally open or normally closed characteristics to achieve specific functions.

Definition of normally open and normally closed

Normally open (NO): In electrical systems, normally open contacts refer to contacts that are disconnected in a natural, non-powered state. That is, when there is no external excitation (such as current or voltage), there is no conductivity between the contacts.

Normally closed (NC): In contrast to normally open, normally closed contacts are closed in a natural, non-powered state. That is, when there is no external excitation, there is conductivity between the contacts.

The role of connecting rods in mechanical systems

The connecting rod is a common connecting component in a mechanical system. It can transmit the motion of one component to another, realizing the transmission, conversion and amplification of force or motion. Connecting rods are widely used in various mechanical equipment such as engines, machine tools, robots, etc.

Understanding of normally open and normally closed connecting rods

Although "normally open and normally closed connecting rods" is not a standard term, we can understand this concept from the following aspects:

Combination of connecting rods with normally open/normally closed components: In some mechanical or electrical systems, connecting rods may be combined with components with normally open or normally closed characteristics (such as electrical contacts, switches, etc.). For example, a switch driven by a connecting rod may have normally open or normally closed contacts to control the on and off of the circuit.

Mechanical logic control: In some complex mechanical systems, the transmission and coordination of connecting rods can achieve normally open and normally closed functions similar to those in electrical logic. For example, in some automated production lines or robotic systems, functions similar to electrical interlocking or self-locking can be achieved through the precise design and motion control of connecting rods.

Examples of practical applications

Safety switches: On some machines or equipment, safety switches with normally open contacts may be used. When the safety door or protective cover is opened, the connecting rod drives the switch contacts to disconnect, thereby cutting off the power supply or activating the alarm device to ensure the safety of personnel and equipment.

Automated production line: In an automated production line, the connecting rod may be combined with other mechanical components and electrical components to achieve complex motion control and logic control. Among them, the normally open and normally closed contacts may be used to control the start, stop, fault alarm and other functions of the production line.

Conclusion

In summary, "normally open and normally closed connecting rod" is not an independent term or component, but describes a possibility of combining the connecting rod with the normally open and normally closed components in the mechanical system. In practical applications, it is necessary to select appropriate connecting rods and normally open and normally closed components according to specific needs and system design to achieve the required functions and performance.
