There are several stations that need to adopt cold pressing process in the production of cold pressed terminals, and the manufacturers of cold pressed terminals need to pay more attention to these places, that is, the four cold pressed terminal stations that need to be paid attention to in the cold pressed terminals.
1. Cold press pliers
When using the cold press pliers, check whether the cold press pliers are aligned, and the bolts next to the cold press pliers should be aligned. Ensure that the cold clamping arm can be self-locking when pressed, and can spring up freely after pressing the arm. Confirm different types of pliers. The pliers of OPT cold press pliers are generally 1.25-1.5, 2-2.5, 5.5-6 and 8-10 from high to low. After the first crimping operation of the cold press pliers is completed, check the first finished product to ensure that the cold press jaws are correct, the cold press joints are firmly crimped, and the molding is beautiful.

2.Line terminal
To understand the type of cold pressed joint, whether it is ot type bare end, fork type pre insulated end or pin type pre insulated end, you must have a certain understanding. In the production of cold pressed terminals, the selection of appropriate cold pressed terminals is also very helpful to the production efficiency of products. Precautions: separate the welding terminal from the cold pressing terminal.
3. Cold press connection operation
When pressing lines, straighten the cold pressed joint and do not allow oblique pressure. Positive pressure refers to that the opening of the cold pressed joint faces the convex surface of the cold pressed jaw and the back faces the semicircular surface of the cold pressed jaw. Do not press the terminal with small pliers; Otherwise, it is easy to break the terminal and damage the cold press pliers. Do not press the small terminal with large pliers. Otherwise, the crimping is not tight and the conductivity is poor. Choose the appropriate terminal clip, not too small or too large. Plastic terminals with insulating skin can be slightly enlarged on the basis of the original terminal size.
4. Crimping
The positive current feedback and negative voltage feedback are twisted together with the shielding layer of the shielding wire, and the stripping length is 7.5mm. Both ends of the safety seat are 0.5mm2 red plastic flexible wire, with a stripping length of 15mm and a back bend of 7.5mm. The negative feedback current is 0.3mm2 of black wire in the shield wire, and the stripping length is 15mm, and then it is folded to 7.5mm. The ship's switch wire is 0.5mm2 plastic flexible wire, with a stripping length of 15mm, and then bend back 7.5mm. Select the appropriate wiring cap according to the thickness of the specific line, which is generally used φ 3、 φ 4 two.
