Precisetool Terminal Tension Testing Service

 Precisetool provides professional terminal tensile testing services.

1. Terminal mapping and document creation

After receiving customer's terminals (jack/pin) and wire samples, first of all, the technical staff performs terminal mapping. The mapping process must be meticulous and rigorous to ensure the accuracy of the data. Then, the technical staff performs the terminal sorting and information screening to ensure the integrity of technical information and to provide customers with the most economical and reasonable selection of tools.

2. Preliminary selection

Secondly, model selection of terminal crimping tool, crimping tool selector position, as well as positioners. Selector position determined by a professional formula. This formula comes out after numerous attempts and tests and has high applicability and accuracy. But the result is still a theoretical selector position, taking into account the actual rebound of material and other factors, the tensile test is needed to determine the ultimate reliability.

3. Terminal crimping

Use the selected crimping tool for terminal crimping. Position #6 of pneumatic crimping tool YJQ-W3Q is suitable for the terminal above. Use the YJQ-W3Q to crimp the wires and terminals according to the correct operating procedure.

4. Image collection

Take pictures. Including the terminals before and after crimping.

5. Terminal tensile testing

As the selector position calculated by the formula is theoretical, it can not fully ensure the reliability of the terminal tension value. So a terminal tensile test is necessary.

6. Experimental analysis and summary

The results of the tensile test are made into a tensile test record table. The recommend  model and related data, such as terminal name, wire size, positioner, crimp outer diameter, crimp inner diameter, crimp position parameters, test tension value, and diagonal value etc., should be clearly presented in the test record table. Draw tensile test chart which makes the test results more intuitive. The results show that the position #6 achieve the standard tension. Of course, customers need to perform other related performance testing.

After packaging crimped terminal, stick the label: number, customer name, time, selection of tools, suitable positioner and other information. Finally, send the terminal information table and tensile test record table to customers. Crimped samples send back to customers for reference, and do other performance testing and then make the final tool selection.
