What are the four connection methods of connectors and the advantages of IEC power connectors

Connector is one of the electronic devices that everyone is very familiar with. To enhance everyone's understanding of Connectors, ZOOKE Zhongke Connector brand will introduce the relevant knowledge of connectors based on three points: 1. Introduction to the four connection methods of connectors, 2. Introduction to the advantages of IEC power connectors, and 3. How to detect the quality of connectors.
1. Connector connection method
1. Thread connection method
A type of connection commonly used for connectors with larger size contacts and working in strong vibration environments. This type of connection can be installed with a fuse to prevent loosening after the connection is completed. This connection form is reliable in use, but the unloading speed is slow.
2. Bayonet connection method
It is a reliable and rapid form of connection and separation. Most connectors with card 121 connections have a visual display of correct connection and locking, which can be observed from the small hole on the side of the connector connecting nut.
3. Plug and unplug connection method
It is a versatile form of connection. The direction of movement of the plug and socket of the connector during connection and separation is usually a reciprocating linear motion, without the need for twisting or rotation. It only requires a small working space to complete the connection and removal. There are two common types of plug-in connections: ball or pin structures. This connection form has no mechanical labor-saving mechanism, and once inserted incorrectly, the mechanical resistance significantly increases, which can be detected in a timely manner.
4. Cabinet connection method
The connector used on certain devices that require blind connection near the frame can make electrical equipment lighter, smaller, easier to maintain, and more reliable. This type of connection makes it impossible for the operator to feel the connection, and a precise positioning device must be designed to avoid forcibly connecting the connectors that were mistakenly inserted together, making mistakenly inserted impossible. Cabinet type circular push pull self-locking connectors usually adopt floating or elastic contact design structures to ensure their correct connection.
2. Advantages of IEC power connectors
IEC connector, which is a common name for thirteen types of power cord connectors. Defined by the International Electrotechnical Commission (IEC) specification IEC60320, these IEC connectors are widely used for power connections in electrical and electronic equipment. 13 different types of IEC power connectors have been defined. The IEC power connector also has variants of two or three conductors and different current variants, allowing power to be connected to different types of electrical and electronic devices.
IEC power connectors are widely used in household devices, from radios powered by small power sources through computers to items such as electric kettles. The wide variety of IEC connectors means that the same series of products can be used for various applications. So what are the advantages of IEC power connectors?
Advantages of IEC power connectors
The IEC power connector is a standard form of power connector used on electronic and electrical equipment. As a standard format, it is easy to purchase ready-made wires in the market, which makes consumers very attractive to connector manufacturers who can purchase ready-made items at a very cheap price. In addition, various filtering connectors can be provided in a low-cost manner, allowing for the integration of filtering and other functions using standard components. These advantages mean that IEC power connectors are an ideal choice for many electronic device design applications.
3. Connector quality inspection
(1) Manufacturer's inspection connector
Firstly, we understand the basic appearance standards for connectors, which are composed of terminal rubber shells and needle bases. We divide them into pre assembly and post assembly inspections:
Inspection before assembly: shortage of materials, burrs, shrinkage, deformation, color difference, dirt, blockage, indentation, uneven/deformed partition board, sticking points, sinking/deviation or fracture, incorrect/no PIN identification
Inspection after assembly: Check if there is any gap between the copper shell/iron shell and the rubber shell, if the iron shell/copper shell is deformed, if the buckle is not pressed in place/deviated, if the rubber shell is damaged, if the left and right hooks are not installed in place (the exposed dimensions of the hooks at both ends are inconsistent), press the hooks several times by hand to confirm if the left and right hooks are normal and have elasticity
The above are all factors for eliminating defective products by connector manufacturers during product testing, removing the defective products inside. These are all the testing steps in the manufacturer's quality inspection.
(2) Personal detection connector
There are still some that appear to be fine on the surface, but are damaged internally. And experts can directly determine the quality of connectors by touching, smelling, and seeing.
1. Touch and feel with your hand whether the production of the connector is meticulous. If there is a noticeable roughness on the surface and the lifespan is not guaranteed, there is a huge difference in safety between the connector and high-quality products.
2. Smell, some manufacturers may add fragrance to mask the taste of inferior materials, so when encountering products with fragrance, it is necessary to carefully consider them.
3. Look, if you see severe oxidation of connectors and sockets on the metal surface, which is basically a gray color with similar degrees, these are all quality issues that can affect the welding quality. Generally, connectors that have not been used will not show oxidation or damage in appearance.as
