smc 1.27mm connectors As a key component of electronic and electrical equipment, is the main medium of signal and power transmission in the circuit. When the smc 1.27mm connectors are disconnected, the part with resistance will heat up and the temperature will rise, so the contact part is the main part of the connector heating. However, the change of temperature rise within the normal range is normal and will not affect the use; When the connector is too hot and the temperature rises too high, it is an abnormal situation that requires intervention.

Because the temperature rise is an important performance indicator for the long-term use of aviation plugs. So, if the temperature rise of the aviation plug is too high, what harm will it cause? smc 1.27mm connectors How should manufacturers ensure that the temperature rise of the product is within a reasonable range?

The harm of excessive temperature rise

smc 1.27mm connectors The harm of too high a temperature rise is actually very large. When the connector connects the circuit circuit through the current, the resistance of the contact part itself and the contact resistance generate heat. As the heat continues to gather, the temperature of the contact parts will continue to rise. Once too high, the stress on the contact component will relax, which will lead to a high contact resistance, which will then weaken the electrical signal, which will then lead to a short circuit. In addition, the high temperature of the product will also accelerate the surface corrosion of the contact parts, shorten the life cycle, and even fire and explosion, endangering the safety of the user.

In short, if the smc 1.27mm connectors are severe and the temperature rise is too high for a long time, it will inevitably lead to serious problems such as short circuit or fire.

How to ensure the normal temperature rise?

Excessive temperature rise is a major killer of the safety and characteristics of aviation plug connectors. How do manufacturers of aviation plug connectors achieve temperature rises to meet normal requirements? It is mainly guaranteed from the following two aspects:

Contact material selection

Contact parts of smc 1.27mm connectors use highly conductive materials to help reduce temperature rise. For electrical connectors with high rated voltage, contact parts with high electrical conductivity and materials with certain mechanical properties, such as chrome-zirconium copper alloy, should be selected.

Coating design

Contact parts are usually treated with a surface coating process to prevent excessive temperature rise. This is because copper is easy to oxidize with the gas, producing an oxide layer, resulting in an effective reduction of the contact point and promoting an increase in temperature. After coating treatment, the inactive metal in the coating metal and nickel can isolate the oxidation reaction. At present, the surface of the contact parts is mostly gold-plated or silver-plated, and the thicker the coating film, the more conducive to temperature rise. Of course, taking into account the cost, the coating thickness is measured according to the actual application requirements.
