Sudden high temperature often make melting, distortion, deformation of bubbles and Terminal. Assembly time is generally divided into several-minute warm-up period, the peak for a few seconds, and a few minutes cleaning and drying period. Of course, choosing the right metal, resin can improve the reliability of welding.
Welding conditions are significantly different from, depending on how the UK terminal block type and welding process steps. Used in wave soldering, installed on the PCB Board of UK terminal block is typical of the perforated mounting type. Perforation of welding pins must be accurately locate, size, balanced place, and good weldability to facilitate insertion and welding. Throughout the Assembly process, must stand up to high temperature and preheating by wave soldering conduction to the post body temperature. And for lots of wires interconnecting, in the electric power industry has a dedicated Terminal, terminal box, above all terminals, single-layer, double-layer, current, voltage, normal, broken, and so on.
The crimp area must be in order to ensure reliable contact, as well as guaranteed by sufficient current. Their general specifications all UK series universal terminal blocks can be used to meet the requirements of EN50019 standard EEXe area. Corresponding chartered component of Ex-proof certificate number can be found under the terminal data, with finer wire dimensions is similar to the smaller sister model, wire cross section greater than 6mm2 Terminal dimensions has been optimized. UK terminal block heaters must be crimping terminals correspond to the wires one by one, eliminate the short circuit accident due to crimping. Terminal blocks inside metal conductors are core parts of the Terminal, it will come from external wires or cables of voltage, current or signals to the matching connector on the corresponding contacts. Electrical connector design requirement is to effect a oxide film UK terminal block when combined with rupture, and ensure access in the life of the electrical connector interface no longer be oxidized. Re-oxidation corrosion, wear and corrosion, is Tin contact mechanism of most major performance degradation of the coating.
As the wire break in the middle of the fault is very rare, are mostly in Terminal is disconnected, therefore, when checks should focus on carefully check the sensor and connect along wires, loose and poor contact. Caused by poor contact between terminal block broken fault, often is due to terminal block end to corrosion, outside dirt entering the terminals or connected socket, resulting in reduced contact pressure.
