The reasons for the failure of the customized connector are summarized in four aspects: the degree of wear, improper selection, extreme temperature, improper design and installation, and the specific contents are as follows:
1. The degree of wear of the custom connector
Repeated connection and disconnection of the product will cause the metal on the contact to wear and corrode when exposed to water, dust, dirt and other irritating elements, so that the mating pin may not be properly engaged when inserted into the connector housing.
2. Improper selection of custom connectors
For example, it is to choose a special industrial connector suitable for the humid environment. If a standard connector is used instead of a connector with an IP68 or IP69 rating or a sealed design, water will cause the connector to malfunction. Choosing a connector that is too small will also reduce efficiency and shorten the life of the connector.
3. The extreme temperature of the custom connector
If the rated temperature of the connector is not very high or very low, then their ultimate fate is also failure. Do you know why? Because the connector is not suitable for high temperature, the insulation will fail and the conductivity will also have a peak. If operated at a sustained high temperature, these spikes will increase the temperature, which may cause corrosion and ultimately reduce the contact force. This affects the electrical signals propagating through the connector and cable assembly.
Although cold temperatures will not affect the connectors as severely as high temperatures, if you know that your application requires them, you should consider low-temperature designs. Exposure to sustained low temperatures will cause the tinned connector material to soften, thereby increasing contact resistance. In addition, low temperatures can affect other parts of the connector, such as making the plastic shell brittle.
4. Improper design and installation of custom connectors
Product applications will encounter shock, vibration and other destructive factors, and those safety designs that can produce strong locks are very important. If it is not firmly installed, the connector contacts, mating shells and even cables may be damaged. In addition, connectors and cable assemblies must have proper strain relief and installation wiring, and use guide grooves, cable brackets and cable glands to help ensure a rated connector assembly life.
Regardless of whether it is a customized connector or a non-customized connector, the above four reasons will cause the product to fail. Therefore, I hope users and friends will keep the above four points in mind, and pay attention to avoiding the failure of the connector, and extend the customization for a longer time. The life of the connector.
