Steps To Buying A Heavy Duty Connector

Steps to buy heavy duty electric cable connectors

Connectors are widely used electronic devices in industry and are used for various connection work. However, in special harsh industrial environments such as dust, humidity and mechanical stress, we need a stronger, more durable and more durable connector to connect the interfaces of wires and equipment. At this time, you need a special force in the connector-heavy duty automotive electrical connectors.

So the question is:

Generally everyone will choose a connector, but how to choose heavy duty 12v connectors?

Determine the connection method of the connector.

Screws, shrapnel, straight plug, cold press, coaxial screws, etc.

The three connection methods of screws, shrapnel and straight plug do not require additional purchase of accessories, are cheap and easy to operate.

Screw and shrapnel types require screwdrivers to connect, the connection process is simple and convenient, and later on-site maintenance is more flexible.

The straight plug type does not require tools and is directly wired, but the price is higher than the screw and shrapnel type.

The cold press type requires the purchase of special male and female pins, and special crimping tools are required for crimping and disassembly.

Purchase Tips: Buy screws and shrapnel, directly insert the model, and consider the actual situation such as price, wiring convenience, and later maintenance when purchasing. Cold pressing requires a special pressure connection tool, which has high requirements for operators. But it is more reliable than other methods, the tool is expensive, the overall cost is high, and it is suitable for standardized mass assembly.

The second step is to determine the number of circuits, voltage and current.

When designing the heavy duty 12 volt connectors schematic, the designer should choose the cable as a bridge to connect the two ends of the cable to transmit power or signals. The number of cores and diameter of the cable should be determined mainly according to the transmission voltage and current to determine the maximum diameter, number of cores, rated voltage and rated current of the cable.

Purchase Tips: Whether it is a cable or a connector, the transmission voltage and current must be lower than the rated voltage and rated current of the cable and connector. In some power transmission processes, the transmission current is often greater than the rated current of the circuit, and the wiring diameter range is limited. In this case, a cable with a smaller wire diameter can be selected, but the power of the same potential is transmitted by two core wires together, which will increase the number of circuits instead of a large-diameter cable.

The third step is to determine the cable connector.

For different cable connectors, plastic and metal connectors are generally provided, and three protection levels of IP54, IP67, and IP68 can be selected. In addition, the thread specifications of the cable connectors are from the public and the UK.

Purchase Tips: Determine the outer diameter of the cable above, and then easily select the specifications of the cable connector according to the use requirements of the connector protection level.

Step 4, confirm the shell type.

A sturdy shell can help the connector withstand frost and vibration.

Purchase Tips: 12v heavy duty connector of different protective shells, shapes, sizes, and line entry methods are all different.
