Problems solved by technology

However, the above-mentioned control method, because it only controls the reliability of the connection between the wire and the terminal from the appearance and the method of mechanical tension, cannot clearly identify the actual active part and connection status inside the wire and the terminal, resulting in repeated use. , there will be a risk of unreliable and broken connections

Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] Such as figure 1 Shown is the metallographic grinding diagram of terminal crimping. The metallographic control method of terminal crimping provided according to the embodiment of the present invention includes the step: S1, using a grinding tool to grind the part of the front leg of the terminal to press the copper wire to the middle of the front leg crimping ; S2, using acidic solvent and alcohol to remove the copper shavings generated on the surface of the crimping body during the grinding process; S3, using CCD (Charge-coupled Device, charge-coupled device) to observe the metallographic diagram of the crimping and through the two-dimensional measurement tool Car...

Abstract

The invention discloses a metallographic control method for terminal crimping, which comprises the steps of: grinding the part of the copper wire pressed by the front leg of the terminal to the middle part of the crimping of the front leg; removing the copper shavings produced on the surface of the crimping body during the grinding process; Observe the metallographic diagram and measure it with a two-dimensional measuring tool; compare the crimping metallographic diagram with the metallographic standard diagram to determine the crimping quality. Through the metallographic control method of terminal crimping of the present invention, the quality control of terminal crimping is improved on the basis of the control of the original height, width and tensile strength. The method of the present invention can be very directly through appearance comparison and CCD projection The results confirm the reliability of terminal crimping, the control level of lifting terminal crimping is higher, and the firmness of terminal crimping part is improved.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a metallographic control method for terminal crimping. Background technique [0002] At present, the connection control of wires and connectors in the industry is basically based on crimping, welding and welding. For various types of single wires, coaxial cables, shielded wires and twisted pairs, when considering When using destructive methods and using less skilled personnel to control quality, crimping is identified as the most important method. Most of the tools and machines used for crimping have full cycle characteristics and do not require operators. By any judgment, such high pressure terminations are hermetic, making them insensitive to mechanical, thermal and chemical stresses that may exist in a typical system. The use of high-speed crimping machines and the use of pre-processing techniques reduce assembly costs and allow the crimping characteristics of t...
