Five Characteristics of High-Reliability Connectors

Connectors are an indispensable component of electronic equipment. The importance of building a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow, and the circuit can realize the predetermined function. Connectors products selected for specific application environments usually require high reliability, and the reliability of Connectors must be ensured to meet application requirements, and high reliability refers to the use of Connectors. So how to judge whether Connectors have high reliability? Mainly look at the following five aspects! Here are some answers.

Here is the content list:

l High-reliability Connectors should have a stress relief function.

l High-reliability Connectors should have good vibration and shock resistance.

l High-reliability Connectors should have a solid physical structure.

l High-reliability Connectors must have high durability.

l The operating temperature range of high-reliability Connectors must meet the specifications.

High-reliability Connectors should have a stress relief function.

The electrical connection of Connectors usually bears greater pressure and stress than the board connection, so Connectors products need to have a stress relief function to improve their reliability.

High-reliability Connectors should have good vibration and shock resistance.

Connectors are often affected by vibration and shock factors, resulting in connection interruption. To deal with such problems, Connectors must have good vibration and shock resistance to improve their reliability.

High-reliability Connectors should have a solid physical structure.

Unlike electrical connections separated by electric shocks, to deal with undesirable factors such as impact in a special environment, Connectors must have a solid physical structure to prevent the contacts from being damaged by unfavorable factors during the mating process, thereby improving the reliability of the connector.

High-reliability Connectors must have high durability.

Generally, the plug-in service life of Connectors maybe 300-500 times, but the connector for specific applications may require its plug-in service life to reach 10,000 times. Therefore, the durability of the Connectors must be high, and it is necessary to ensure that the durability of the Connectors meets the standard requirements of the plug-in cycle.

The operating temperature range of high-reliability Connectors must meet the specifications.

Generally, the operating temperature range of Connectors is -25°C to +85°C, and the highest is -40°C to +105°C. The range of high-reliability Connectors will push the lower limit to -55°C or -65°C and push the upper limit to at least +125°C or even +175°C. At this time, you can generally select materials (such as higher grades). Phosphor bronze or beryllium copper contacts to achieve the additional temperature range of the Connectors, and the plastic housing material needs to be able to maintain its shape without cracking or deforming.
