What are the four causes of connector failure?

Although each connector has a rated service life, incorrect design and other factors can also lead to premature failure of connectors for industrial mechanical equipment, leading to expensive mechanical equipment damage. Therefore, some factors that cause connector failures are worth noting. The following are four common factors shared by Xinpeng Bo connector manufacturers. Let's take a look!

1. The issue of connector wear

Repeated connection and disconnection of connectors can lead to wear and corrosion of metals exposed to water, dust, dirt, and other irritating elements, resulting in incorrect connection of mating pins when inserted into the connector housing.

2. Improper selection of connectors

If the size or specifications of the connector product are not suitable, it will not only reduce the efficiency of use, but also shorten the service life of the connector.

3. Temperature issues in the application of connectors

If the rated temperature of the connectors is not very high or low, they will eventually fail because the connectors are not suitable for high temperatures, insulation failure, and conductivity will also peak. If working at sustained high temperatures, these peaks will increase the temperature, which may lead to corrosion and ultimately reduce contact force. This will affect the electrical signals transmitted through connectors and cable components.

Although cold temperature does not seriously affect connectors as high temperature does, if applications are needed, low-temperature design should be considered. For example, the application of connectors at continuous low temperatures can lead to softening of the tinned connector material, thereby increasing contact resistance. In addition, low temperatures can affect other parts of the connector, such as making the plastic casing brittle.

4. Improper connector design and installation

If the application of connectors encounters destructive factors such as impact and vibration, then a safety design that can generate strong locks is very important. If the installation is not secure, connector contact, housing, and even cables may be damaged.

In addition, connectors and cable components must have appropriate strain relief and installation wiring. The use of guide grooves, cable brackets, and cable glands can help ensure the assembly life of rated connectors.
