Technical Basis of Connectors
1、What is a connector?
Connector is a part of our electronic engineers and technicians often contact. Its role is very simple: in the circuit is blocked or isolated between the circuit, bridging the communication, so that the current flow, so that the circuit to achieve the intended function. Connector is an indispensable part of the electronic equipment, along the current flow path, you will always find one or more connectors. Connector form and structure is ever-changing, with the application object, frequency, power, application environment, etc., there are different forms of connectors. For example, the connector used to light the lights on the field and the connector of the hard disk drive, and the connector of the ignition rocket is very different. But no matter what kind of connector is used, it is important to ensure a smooth, continuous and reliable flow of current.
In terms of generalization, what is connected by connectors is not limited to electric current. In today's rapidly developing optoelectronics, the carrier of signals in fiber optic systems is light, and glass and plastic replace the wires in ordinary circuits, but connectors are also used in optical signal paths, and they serve the same purpose as circuit connectors. Since we are only concerned with circuit connectors, this course will focus on circuit connectors and their applications in close conjunction with Molex's products.
2、Why use connectors?
Imagine what it would be like if there were no connectors? For example, if an electronic device is to be connected to a power supply, the two ends of the connecting wires must be connected to the electronic device and the power supply by some method (e.g. soldering). In this way, whether for the production or use, have brought a lot of inconvenience.
Take a car battery as an example. Assuming that the battery cable is fixed soldered to the battery, the car manufacturer to install the battery increased the workload, increased production time and costs. Battery damage needs to be replaced, but also to send the car to the repair station, desoldering to remove the old, and then welded on the new, to pay more labor costs for this. With the connector can eliminate a lot of trouble, buy a new battery from the store, disconnect the connector, remove the old battery, install the new battery, reconnect the connector can be. This simple example illustrates the benefits of connectors. It makes the design and production process easier and more flexible, reducing production and maintenance costs.
3、Benefits of the connector
Improve the production process Easy to maintain Easy to upgrade.
Connectors simplify the assembly process of electronic products. Also simplifies the mass production process If an electronic component failure, equipped with a connector can quickly replace the failed components With technological advances, equipped with a connector can update the components, with new and better components to replace the old.
The use of connectors gives engineers greater flexibility in designing and integrating new products, and in forming systems from components.
Mechanical parameters of electrical connectors
Contact pressure in the connector is an important indicator, which directly affects the size of the contact resistance and the amount of wear on the contact pair. In most structures, direct measurement of contact pressure is quite difficult.
Requirements for electrical parameters of electrical connectors
The connector is an electromechanical component that connects electrical circuits. Therefore, the electrical parameters of the connector itself is the first thing to consider when choosing a connector.
In-depth analysis of the structure and advantages of electronic connectors
An electrical connector, also known as a circuit connector, is a conductor device that bridges two conductors on a circuit so that current or signals can flow from one conductor to the other. An electronic connector is a motor system that provides a separable interface to connect two sub-electronic systems. Simply put
Connector is a part of our electronic engineers and technicians often contact. Its role is very simple: in the circuit is blocked or isolated between the circuit, bridging the communication, so that the current flow, so that the circuit to achieve the intended function.
Introduction of connector standards
A standard is a unified provision made for repetitive things and concepts. It is based on the comprehensive results of science, technology and practical experience, approved by consensus of the parties concerned and published in a specific form by the competent authority as a guideline and basis for common compliance.
Classification of connectors and naming
As connectors become increasingly diverse and new structures and applications emerge, attempts to solve the classification and naming problem with a fixed model have become difficult to accommodate. Nevertheless, some basic classifications are still valid.
