How to use crystal head crimping pliers
In today's era of rapid development of network technology, crystal head crimping pliers, as an indispensable tool in network wiring, have received widespread attention. Whether it is home network wiring or enterprise-level network engineering, it is particularly important to master the correct use of crystal-head crimping pliers. This article will introduce in detail the steps, precautions and solutions to common problems in using crystal-head crimping pliers to help you easily complete the production of network cables.
1. Basic introduction to crystal head crimping pliers
Crystal head crimping pliers are a tool specially used to press RJ45 crystal heads. They usually have three functions: cutting, stripping and crimping. The following are the components of common crystal head crimping pliers:
| Part name | Function description |
|---|---|
| Stripping knife edge | Used to peel off the sheath of network cables |
| Thread cutting edge | For trimming excess cables |
| Crimp groove | Used to crimp and fix the crystal head and cable |
2. How to use crystal head crimping pliers
1.Preparation: Prepare the crystal head, network cable, crystal head crimping pliers and wire sequence standard reference diagram.
2.Peel off the skin: Use the stripping blade of the crimping pliers, gently rotate it in one circle, and peel off about 2-3 cm of the network cable sheath.
3.Organize the line sequence: Arrange the wire sequence according to T568A or T568B standard. Common wire sequence standards are as follows:
| Wire sequence standards | Line order (from left to right) |
|---|---|
| T568A | White green, green, white orange, blue, white blue, orange, white brown, brown |
| T568B | white orange, orange, white green, blue, white blue, green, white brown, brown |
4.Trim threads: Trim the arranged cables neatly, leaving about 1.5 cm in length.
5.Insert crystal head: Insert the cable into the crystal head, making sure that each cable reaches the front end.
6.Crimping crystal head: Put the crystal head into the crimping slot of the crimping pliers, and press it firmly. A "click" sound indicates that the crimping is completed.
3. Precautions for use
1.Line order consistency: All crystal heads in the same network must use the same line sequence standard.
2.Velocity control: The force should be moderate when crimping. Too light may cause poor contact, and too heavy may damage the crystal head.
3.Check quality: After the crimping is completed, check whether the cable is firmly fixed and whether the wire cores are in good contact.
4.Tool maintenance: Regularly clean the cutting edge and crimping groove of the crimping pliers to keep the tool in good condition.
4. Common problems and solutions
| Problem phenomenon | Possible reasons | Solution |
|---|---|---|
| The network is blocked | Wrong line sequence or poor contact | Recheck the wire sequence and crimp |
| Crystal head loose | Insufficient crimping force | Re-crimp with more force |
| Exposed cables | Improper trimming length | Trim again to appropriate length |
5. Purchase suggestions
1.Material selection: Crimping pliers made of alloy steel are preferred for better durability.
2.Functional considerations: Choose a product with three-in-one functions of wire stripping, wire cutting and crimping.
3.Brand selection: Well-known brands such as Sanbao, Lulian, etc. have better quality assurance.
4.price range: It is recommended to choose products priced at RMB 50-100 for ordinary household use, and products priced at RMB 100-300 for professional use.
Summary
Mastering the correct use of crystal-head crimping pliers can not only improve the efficiency of network wiring, but also ensure the stability of the network connection. Through the detailed introduction in this article, I believe you have understood the entire process from preparation to completion of crimping. Remember, practice makes perfect, and more practice will make you a master of network cabling. If you encounter any problems during practice, please feel free to consult professionals.
