How to choose the right electronic wiring harness?

Faced with so many kinds of electronic wiring harnesses on the market, it is the most important thing to find the right one for our electronic equipment needs. A suitable electronic wiring harness not only supplies current transportation to the equipment, but also increases reliability and stability to the interconnected equipment. Therefore, we must carefully consider when choosing an electronic wiring harness. Today, Huichengyuan wiring harness manufacturer will talk to us. How to choose a suitable electronic wiring harness to connect with the equipment?

-------------------------------------------------------------------------------------------------

1. Rated current: Rated current is the most important criterion when selecting electronic wiring harness. It is indicated in amperage per circuit and is a measure of the amount of current that can pass through the paired terminal, and the temperature rise does not cross 85 ° F (30 °C) at an ambient temperature of 72 ° F (22 ° C). This current level then drops or adjusts the number of circuits in a given housing due to the heat (temperature rise) of the adjacent terminals. 2. Connector standards or circuit density: With the trend of shrinking equipment standards, electronic wiring harness standards are becoming more and more important in the selection process of wire connectors. Circuit density is a relative measure of the number of circuits that an electronic wire harness can contain per square inch. It is relative. Using this method, the space requirements or standards of one coupling series and another coupling series can be objectively recognized.

3. Wire standard: When selecting a suitable electronic wiring harness, wire standard is an important standard, especially in applications where the required current rating is close to the maximum rating of the selected coupler series, and the mechanical strength of the required wire is applied. In both cases, a heavier wire gauge should be selected. 4. Rated operating voltage: Most applications are within the 250V rated value range of standard electronic wiring harnesses. For example, the CH3.96 wire-to-board connector supplies a rated current value of 5.0 A AC/DC. The rated voltage value is 250V AC/DC, which is suitable for both AC and DC voltages. Higher voltage ratings are typically achieved by completely enclosing the male and female terminals individually in the housing. Those shrouded housings and completely barrier contacts also provide protection to the metal terminals during assembly and handling of the wire coupler. 5. Shell confession type: Select the type of electronic wiring harness suitable for using forward confession, preferably based on the stress degree accepted by the cooperative electronic wiring harness. An electronic wiring harness system with forced confession requires the operator to deactivate the confession device before the coupling halves can be separated, while the forced confession system will allow the coupling halves to disengage by simply separating the halves with moderate force. In high vibration operations or when wires or cables are subjected to axial loads, whether design or accident, the electronic wiring harness should be regularly passed forward. VI. Strain relief equipment: The strain relief equipment or rear shell used for electronic wiring harness can be the primary standard for the rated safety of the wrong conductive strain relief shell supply. Assuming that the terminal or wire is displaced from its place in the electronic harness housing due to mechanical overstress, the strain relief may prevent the "live" wire from touching other components or "neutral" conductive members. 7. Shell and terminal materials and termination plating: Materials and plating are generally one of the final first choices. Most electronic wiring harnesses are made of nylon plastic. The nylon typically has a flammability rating of UL94V-2 of 94V-0. A higher 94V-0 grade indicates that nylon will pause faster (in the event of a fire) than 94V-2 nylon. The 94V-0 rating does not infer a higher operating temperature rating, but rather a higher flame retardancy. For most applications, 94V-2 material is sufficient.
