The newly released multiple terminal products of Jointlean Electric adopt a spring fastening type direct insertion installation method, using spring clips as fasteners. On the one hand, it is convenient for wiring, and the installation can be completed by directly inserting the wire; On the other hand, it is convenient for later maintenance, without the tedious operation of screwing screws, and easy to detect; Furthermore, shrapnel also has anti vibration properties, making it more stable compared to screw fastening.

Many customers who are not familiar with spring wiring often send some questions. Below, we will ask everyone for clarification.

1. If the voltage exceeds 48V, the wiring will become unstable, heat up, and there is a risk of combustion?

Answer: Terminal heating is not related to voltage. The product has undergone a 4500V high voltage test without any breakdown, so there is no voltage related issue; Terminal heating and burning are caused by poor contact or excessive current. As long as the wire diameter is 2-2.5 square millimeters and does not exceed the rated current of 20A, the temperature rise can be maintained within the national standard range of 45K.

Will it cause a decrease in elasticity over time?

Answer: As long as it is used normally and no overload force is applied, the elasticity will not weaken. But as time goes on indefinitely, as the stainless steel material slowly oxidizes and corrodes in the air, the characteristics of the spring change, resulting in weakened elasticity, which may cause elastic decay.

There are two reasons for the deterioration of spring elasticity:

1. Enduring elastic deformation beyond the specified range can result in loss of resilience;

Over time, the spring material undergoes degeneration and its elasticity weakens.

In summary, as long as it is used within a reasonable range, there is no need to worry about the elasticity and fastening force of the terminal. The spring wire pressing method has a history of 50 years since its invention in the 1970s. Its market application scope is becoming wider and the number of installations is increasing. Now, there are billions of interfaces every year. Practice is the only criterion for testing truth, and market orientation indicates that there are no structural problems with spring terminals. As long as the product materials are excellent and the quality is up to standard, it can be used with confidence.
