The electrical performance secrets that connectors have to say

As an essential electrical device, connectors are primarily used for connection and conduction. Among various materials, metals have the most outstanding conductivity, making their usage irreplaceable. However, metals also possess their own "personality," referred to as resistance in physics, which is a crucial factor in the electrical performance of connectors.

There are many types of power connector battery plugs, which exist in different corners of our surrounding environment. We may use connectors unconsciously in our daily life. So, what exactly is a connector? To understand better, let's consider items in our homes. For example, a plug for a desk lamp, an interface for a USB flash drive, or a jack for headphones are all examples of small quick-connect connectors. Larger connectors, on the other hand, may be familiar to you, as they can be found in control gear or fiber optic connectors in your car.

There are many classifications of resistance, but today we mainly focus on analyzing the electrical strength of the battery plug connector of fast power supply products. Signal transmission needs to be loaded with electric waves, using the power transmission ability in the conductor. However, if there is interference or operational problems in the transmission of electricity, like a ship navigating a river, signal errors and loss can occur. This situation must be resolved.

To account for interference, the current needs to remain within the transmission line without being affected by other signals. Solutions to this situation include incorporating EMI shielding on the mating portion of the connector. During the test, a certain range of frequencies is loaded into the connector, and the attenuation of the transmission frequency after passing through the connector is checked to determine whether the connector meets the required standards.

Regarding the issue of transmission delay, it is mainly attributed to internal factors of the metal. Different metals possess varying resistance values and require different cross-sectional sizes. Consequently, the design and material selection for a specific connector demand careful consideration.
