Effect of Crimp Height on Terminal Electrical Performance
The contact between the terminal and the wire is not completely in contact, but scattered at some points on the contact surface. The difference between the actual contact area and the theoretical contact area may reach thousands of times. The resistance formed by the contact between conductor and conductor is called contact resistance, which is […]
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 […]
Several aspects to consider when choosing a connector
1. Pins and spacing The number of pins and pin spacing are the basic basis for connector selection. The number of pins chosen for the connector depends on the number of signals that need to be connected. For some chip connectors, the number of pins should not be too many. Because in the welding process […]
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 era of the Internet of Things is accelerating
IoT scenarios such as automated factories and remote health monitoring are gradually becoming a reality with the maturity of network technologies such as 5G cellular and WiFi 6+. They have larger data capacity and faster speeds, and can support the connection of millions of devices at the same time, enabling relatively simple smart homes to […]
How to classify electrical connectors by different operating frequencies?
Different fields have different operating frequency requirements for connectors, and usually divided into low-frequency, high-frequency and mixed-frequency electrical connectors. The specific division method is as follows: 1. Low-frequency electrical connectors. The standard for the division of high and low frequencies is generally 100MHz. Therefore, low-frequency electrical connectors usually refer to electrical connectors whose transmission […]
Terminal Design Parameters
The design parameters of the terminal generally refer to the parameters of the crimping part, mainly referring to the inner and outer diameters of the terminal, joint length, depth, number and arrangement of dents. ① Inner diameter and outer diameter. The inner and outer diameters of the terminal determine the thickness of the terminal. The […]
Performance comparison of different wires
1. Ordinary wire Regular wire is usually made of many strands of thin copper wire. The multi-strand form has good bending resistance and is not easy to break due to repeated vibrations. Common conductors consist of two parts: a copper core and insulating material. Polyvinyl chloride material is usually used for insulation and has the […]
