Terminology
A reusable, insulated or uninsulated connecting device consisting of a flexible wire terminal with a plug and a mobile socket for electrical connection of external wires. Terminals are non reusable, insulated or uninsulated connecting devices used for electrical connections of external wires. Clamping piece is a terminal or parts used for mechanical clamping and establishing electrical connections with one or several wires. Thread type terminals. Terminals used to connect a wire and subsequently remove the wire, or for extending the connection of two or more wires (insulation must be removed). Threaded terminals establish connections with wires directly or indirectly through any type of screw or nut A threaded terminal in which a wire is inserted into the socket or slot of the terminal and clamped by a screw rod. The clamping force can be applied directly through the screw rod or through the plug-in component (under the pressure of the screw rod). Screw terminal - a type of threaded terminal in which the wire is clamped by the screw end, and the clamping force can be applied directly through the screw end or through a plug-in component (such as a gasket, pressure plate, or a component that prevents displacement). Note: An example of screw terminals is shown in Figure 3. Bolt terminal - a type of threaded terminal where the wire is clamped by a nut, and the clamping force can be applied directly through the nut or through plug-in components (such as gaskets, pressure plates, or other components that prevent displacement). Note: An example of screw terminals is shown in Figure 3. A threaded terminal in which the wire is clamped by two or more screws or nuts through a clamp. Note: An example of screw terminals is shown in Figure 4 A cover type terminal is a threaded type terminal, in which the wire is clamped at the bottom of a groove between the nut and the threaded bolt. The wire is clamped at the bottom of the groove through a suitable molded gasket under the nut (for locking nuts, through an intermediate pin) or an equivalent mechanism that transfers the contact pressure of the nut to the wire in the groove. Note: An example of screw terminals is shown in Figure 5
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
1. The testing industry is fully covered, meeting different testing needs
2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate
4. Free initial testing, with no testing fees charged
5. Self service order delivery for free on-site sampling
6. Short cycle, low cost, and attentive service 7. Possess authoritative qualifications such as CMA, CNAS, CAL, etc 8. The testing report is authoritative and effective, and is generally used in China
