Neutral Block Production And Installation: Details Determine Success Or Failure
As a key component of electrical connections, the production and installation quality of neutral blocks directly affects the stability and safety of circuits. If details are ignored, it may lead to serious consequences such as poor contact, heating, and even fire, so every link must be strictly controlled.
Accurate selection, adapted to different scenarios
Select appropriate wiring terminals based on wire specifications, current size, and usage environment. For example, copper terminals with high current carrying capacity and good heat dissipation should be selected for high current lines; In humid environments, nickel plated or stainless steel terminals with moisture-proof and anti-corrosion properties should be selected. If the selection is improper, such as using large terminals for small wire diameters, it will lead to insufficient pressure on the contact surface, causing loosening and heating; Using small terminals for large wire diameters may cause damage to the insulation layer due to compression deformation, posing a safety hazard.
Standardize production to ensure quality
When making wiring terminals, it is necessary to use specialized tools to peel off the insulation layer of the wire to avoid damaging the wire core. The stripping length should match the terminal crimping area. If it is too long, it is prone to short circuit, and if it is too short, it will result in poor contact. When crimping, ensure that the tool corresponds to the terminal model, apply pressure evenly, and tightly bond the wire core with the terminal. For example, using a hexagonal crimping mold can increase the contact area and reduce resistance; After crimping, check for burrs and cracks to ensure that the terminal surface is smooth and free of deformation.
Fine installation ensures reliability
When installing wiring terminals, it is necessary to follow the principle of "fixing the terminals first, then connecting the wires". Install the terminals firmly on the distribution box or equipment to prevent loosening caused by vibration. When connecting wires, ensure that the bolt tightening torque meets the requirements. If it is too loose, it may heat up, and if it is too tight, it may damage the terminals. When multiple wires are connected in parallel, transition terminals or parallel clamps should be used to avoid direct twisting and insufficient contact area. In addition, after installation, it is necessary to tidy up the cables to avoid cross winding and facilitate later maintenance and repair.
Although the wiring terminal is small, it is related to the safe operation of the electrical system. Only by striving for excellence in selection, production, and installation can we build a solid "safety foundation" for circuit connections.
