Mechanical Properties of Connectors

As far as the connection function is concerned, the mating force is an important mechanical property. The insertion force is divided into insertion force and pull-out force (pull-out force is also called separation force), and their requirements are different. There are regulations on the maximum insertion force and the minimum separation force in the relevant […]

What is the significance of the existence of the connector?

Imagine what it would be like without the connector. At this point, the circuits should be permanently connected together with continuous conductors. For example, if you want to connect an electronic device to a power source, the ends of the connecting wire must have some method (such as soldering) to hold the electronic device and […]

What is a connector?

Connectors are a component that electronic engineers and technicians often come into contact with. Its function is very simple: to build a bridge between the blocked or isolated circuits in the circuit, so that the current can flow, and the circuit can realize the predetermined function. Connectors are an integral part of electronic equipment. If […]

Types and selection methods of automobile wiring harness terminals

The harness terminal is a conductive element that can form a circuit with the corresponding conductive element. The terminal includes two kinds of pins and sockets, which play the role of electrical connection. The materials used are good conductors such as copper and its alloys. The surface is plated with silver, gold or tin to […]

Factors that affect wire resistance are as follows

1. Temperature The effect of temperature on various materials is different. For example, the electrical resistance of copper and steel increases with temperature. For some materials, the resistance of the material decreases with temperature. When conducting wire resistance measurements, we need to disconnect the wire under test from the circuit. 2. Cross-sectional area The larger […]

Factors Affecting Terminal Crimp Performance (Part 2)

1. The material of the conductor With the same wire diameter, the current-carrying capacity of the copper wire is larger than that of the aluminum wire, but the weight of the copper wire is also relatively large. Generally, the conductor is bare copper or bare aluminum, but there may be a coating on the outside […]

Factors Affecting Terminal Crimp Performance (Part 1)

1. Terminal material The following characteristics are important to consider when selecting terminal materials: ①The mechanical properties of the material. Strength, ductility, yield strength, hardness, etc.; ②The electrical conductivity and thermal conductivity of the material. There is a proportional relationship between the electrical conductivity and the thermal conductivity. The electrical conductivity is related to the […]

Introduction of high voltage connectors

High-voltage connectors refer to connectors with AC voltages above 1000V or DC voltages above 1500V, mainly used in vehicles, charging facilities, industrial equipment, medical equipment, etc. Electric vehicles have very strict requirements on connector performance. High insertion and removal times, current carrying capacity, CTI value, flame retardant performance and vibration resistance are the key factors […]

The standard of Cat8 network cable

In the field of ethernet communication, when it comes to ethernet cables, it is often mentioned that the Cat5e ethernet cables, the Cat6 ethernet cables and the seven types of ethernet cables are mentioned. However, in recent years, Cat8 cables have begun to be mentioned more, so what is the difference between Cat8 ethernet cables […]

How to Choose a Low Frequency Connector (Part 4)

-Environmental Parameters- Ambient temperature The metal material and insulating material of the connector determine the working ambient temperature of the connector. High temperature will damage the edge material, causing the insulation resistance and withstand voltage performance to decrease; for metals, high temperature can make the contact pair lose elasticity, accelerate oxidation and cause coating deterioration.
