Notes on insulated terminal

The metal conductor in the terminal is the core component of the insulated terminal, from the external conductor or cable transmission voltage, current, or signal to the corresponding contact area of the joint. Therefore, when using only the insulated terminal, you also need to pay attention to some matters to avoid poor contact or danger.

Screws of terminal blocks

When tightening the wiring, the force should be moderate, to prevent excessive force will be bolts and nuts slip buckle. If you find that the bolt and nut of the insulated terminal have slipped buckle in time to replace, is strictly prohibited to use.

When using a screwdriver to tighten or loosen the screw, you must force the screwdriver to tighten the screw, and then tighten or loosen to prevent the screwdriver and screw slippage, resulting in screw damage is not easy to disassemble, especially in the hanging box of common open. If you find it difficult to disassemble the bolt and nut of the insulated terminal, do not act recklessly to prevent deformation more difficult to disassemble. You should give appropriate knocking, or add a screw loosening agent, dilute hydrochloric acid, etc. later disassembly.

Do not use a vise to tighten or loosen the bolt and nut to prevent damage, with a live wrench to adjust the opening to prevent damage to the bolt and nut deformation, resulting in not easy to disassemble.

Wires of the terminal

The same insulated terminal allows a maximum of two wires of the same type and specification. When using easy to loosen or easy-to-contact poor insulated terminal, the wire connector must be typed fastening on the terminal block to increase the contact area and prevent loosening. In the wire connectors or wire noses connected, the middle is strictly prohibited to add non-copper or conductive performance to the gasket.

Wire connectors connected, require a smooth contact surface and no oxidation, wiring nose or copper row connected, can be cleaned in contact with the surface after applying the conductive paste, and then fastened. When the temporary line, a single wire soft wire requirements insulated terminal folded once and then received the empty open under the mouth; single-core hardwire to type received under the opening.

30KW and above motor wiring, the requirements of the motor out of the line and the connection between the motor cable conductor does not allow cross-connected bad conductivity gasket, such as galvanized nuts, flat pad, spring pad, etc. The use of insulation tape winding cable or other equipment to protect the insulated terminal, the insulation layer to be pressed 1/2 the proportion of winding from one end to the other - end, and at least one round trip.

Although theinsulated terminals the use many failures, the use of these failures generally will not cause a threat to the safety of users, as long as there is not a very serious leakage phenomenon, the use of wire terminals is generally safe, so consumers do not need to worry excessively. But now due to the fierce competition in the market, many insulated terminals do not meet the quality standards, so try to choose a more credible brand when buying. We strictly implement quality control measures to continuously improve product quality, to provide customers with competitive products and satisfactory service, a sense of quality service to every employee. All users can be assured to buy our insulated terminals.
