We are professional in the production and sales the Screw Block Terminal for Circuit Breakers, Contactors, Building Electrical Appliances, Electricity Meters, Fuses and other medium and low voltage electrical hardware fasteners. In 2009, our company successfully developed the blanking forming synchronous manufacturing process of the Screw Terminal, changed the structure of the Screw Terminal Block from the mosaic type to the riveted type, and applied for a patent. This improvement of Screw Terminal Wire Connectors not only doubles the production efficiency, but also greatly increases the mechanical strength of the Screw Type Terminal Blocks, providing 0.5-1.0N.m of torque compared to the traditionally constructed Screw Clamp Terminal.
Screw Clamp Terminal Blocks are generated to facilitate the application of wire. Rail Terminal Block is actually a piece of metal sealed in insulating plastic. There are holes at both ends to insert wires. There are screws for fastening or loosening. Screw Clamp Connecting Terminal Block is suitable for interconnecting a large number of wires. There are special Customize Clamp Wire Terminal in the power industry. The terminal box is full of Screw Clamp Terminal Block, single-layer, double-layer, current, voltage, common, breakable, etc.
In fact, there are many classifications of Screw Type Terminal: European-style Electrical Terminal Screws, plug-in Terminal Screw Connector, barrier-type Screw in Terminal Block, spring-type Clamp Terminal Block, track-type Screw Connector Block, through-wall Screw Block Terminal, photoelectric coupling Type Electrical Screw Terminal series, etc.
What should be paid attention to in the special treatment of Screw Clamp Terminal Block and Hardware Fasteners surface electroplating process?
The special surface treatment of the Screw Terminal Block, Hardware Fasteners (Screws, Nuts, Bolts, Washers) are better exert its performance. In order to improve the hardness of the screw, Apollo hardware screws generally choose the electroplating process to treat the surface of the screw terminal.
When the Screws, Nuts, Bolts, Washers fasterners and Electrical Crimping Frame are electroplated, for the safety and effectiveness of the whole process, some matters need to be paid attention to in the operation process of the Column Joint Fasteners. Here's a detailed introduction to the screw surface treatment electroplating process. The precautions are as follows:
1- Clean the Electric Iron Terminal. First, check whether there are burrs, cracks, etc on the surface of the Screws Terminal Block, and polish it;
2-Contaminants on the surface of the Terminal Crimping Frame, such as metal chips, oil or oxide skin, etc., the Frame Screw Crimp Terminals must be thoroughly cleaned before electroplating, so that the effect of electroplating will be better;
3- Grind and eliminate defects such as perforated oxide skin of Terminal Screw Combination welding parts;
4- The minimum tensile strength of the steel of the Screw Fastener Terminals shall not be lower than 1000MPA, and the ground, machined and cold-formed products should be heat treated before cleaning and electroplating to release the stress, the minimum temperature is 190 degrees, and the time is not less than 3 hours.
