What causes the failure of custom connectors

At Deso Hardware Electronic connector The factory has produced many customized series of products. After these products are delivered to the customer and used for a period of time, the connector will fail, so you know customized Connector What is the cause of the failure? In order to let you better understand what causes the failure of the customized connector, the following defense division of Deso Hardware and Electronics will give you a detailed science popularization of this problem.

Custom connector The causes of failure can be summarized as follows: wear degree, improper selection, extreme temperature, improper design and installation

1. Wear degree of customized connector

Repeated connection and disconnection of the product will lead to wear and corrosion of the metal on the contact when exposed to water, dust, dirt and other irritant elements, so that the mating pin may not engage correctly when inserted into the connector housing.

2. Improper selection of customized connector

For example, it is necessary to select special industrial connectors suitable for humid environment. If standard connectors are used instead of IP68 or IP69 grade or sealed design connectors, water will cause connector failure. Selecting a connector that is too small will also reduce efficiency, thus shortening the service life of the connector.

3. Extreme temperature of customized connector

If the rated temperature of connectors is not very high or low, 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 peak. If operated at continuous high temperatures, these spikes will raise the temperature, which may lead to corrosion and eventually reduce the contact force. This affects the electrical signals that are propagated through connectors and cable assemblies.

Although cold temperatures do not seriously affect connectors as high temperatures do, you should consider low temperature design if you know that your application requires them. Exposure to continuous low temperatures will cause the tinned connector material to soften, thus increasing contact resistance. In addition, low temperatures can affect other parts of the connector, such as making the plastic housing brittle.

4. Improper design and installation of custom connectors

The product will encounter impact, vibration and other destructive factors when it is applied. The safety design that can produce strong locks is very important. If not securely installed, connector contacts, mating housings, and even cables may be damaged. In addition, connectors and cable assemblies must have proper strain relief and installation wiring, and the use of guide grooves, cable supports and cable glands helps ensure the rated connector assembly life.

Whether it is a customized connector or a non customized connector, the above four reasons will lead to the failure of the product. Therefore, users are expected to keep the above four points in mind, pay attention to avoiding the failure of the connector, and extend the life of the customized connector for a longer time.
