Let's talk about the cause of din 41612 type f connectors heat and burn. If din 41612 type f connectors have heat damage, which will affect use, what are the reasons for din 41612 type f connectors to heat and burn?

Cage din 41612 type f connectors are used worldwide for electrical connections with high shock resistance and short connection times, coupled with their heat and corrosion resistance. However, there are also some problems in the actual use of cage spring terminals, and the terminal burn failure often occurs, the main phenomenon is the burning and melting of din 41612 type f connectors. The following is a specific analysis of the heating causes of cage terminals.

1. Improper selection of cage terminal accessories

The cage din 41612 type f connectors have many accessories, such as stoppers, short plates and adjacent connectors, corresponding to the corresponding spring terminal type, for example, adjacent connectors of type 281-402 can be used on series 281 terminals. The 282 series terminals can also be used when the insertion is not in place, but due to insufficient carrying capacity, it is easy to cause the terminal to burn when working at full load.

2. The length of wire pressed into din 41612 type f connectors does not meet the specified requirements

Cage din 41612 type f connectors have strict wire length requirements and the corresponding cross-sectional area of the crimp wire has specific range requirements, such as the allowable crimp wire area of din 41612 type f connectors for models 285-635 is 6 ~ 35mm2. Therefore, when the wire is too thin, the conductivity of the wire deteriorates due to the excessive length of the pressed wire and the insulating layer between the wire and the contact area, thus burning the din 41612 type f connectors. For example, at the main line wiring of the power distribution cabinet, the spring terminal uses 285-635, and the main line of the power supply is 16mm2, which has a similar situation and is extremely dangerous.

3. The strip length of wire inserted into din 41612 type f connectors does not meet the requirements

Cage spring terminals have strict range requirements for the cross-sectional area of the crimp wire. If the required range is exceeded, the wire terminal cannot be fully inserted into the din 41612 type f connectors hole, resulting in decreased conductivity. On railway passenger cars, where the number of wires is often higher, it is not permissible to screw together two wires into a din 41612 type f connectors jack when the number of cage terminals is less than required for wire insertion.

4. Cross-sectional area of wires inserted into din 41612 type f connectors does not meet requirements

Cage spring terminals also have strict requirements for wire stripping. For example, din 41612 type f connectors for models 281-681 have wire stripping lengths of 9-10mm. Too short stripping line will make the spring crimp area is too small, easy to cause obvious shedding. For stripping, not only must have rich experience in operation, but also must be equipped with special stripping tools to fix the stripping length.

Therefore, din 41612 type f connectors should be repaired in time in case of heat damage to ensure its good performance.
