Where is hook up wire used?
Hook up wire are widely used for model planes,model cars,model ships,lamps,household appliances,electric heating appliances,meters,automotive repair wire，marine wire,instruments,electric toys, vehicle repair, small household appliances, robots, general mechanical equipment, etc.
If you use a stranded core, the wires are very flexible and the little wires inside are very thin. NUELEAD's new design adds sponge inside the box to keep wires from cluttering. Use solid wire if you want it to stay bent. But you cannot use crimp connectors with solid cores.
Generally, the single-wire conductor determines the wire size according to the diameter, while the stranded wire determines the wire size according to the cross-sectional area. The larger the cross-sectional area, the greater the current that the cable can transmit, and the longer the transmission distance. Bigger wires (smaller gauge count) are always "better" because you'll get less voltage
Drops and heat loss due to resistance, especially with longer wires. But larger wires cost more, are bulkier, and stiffer. So you need to determine what kind of wire to use according to different current and power.
There are two types cable of hook up wire. Solid is not easy to bend and deform, and it is easy to fix. If your wiring range is relatively large and the line is very long, it is recommended that you choose stranded.
Solid Advantages: long service life, not easy to oxidize due to the small ratio of outer circle area / cross-sectional area, and resistant to short-circuit current impact.
Solid Disadvantages: The wire is hard, and it is difficult to straighten after bending. Repeated bending-straightening is easy to be injured, and it is labor-intensive when setting the small tube. It is mostly used in fixed and buried environments.
Stranded Advantages: Because the wire is relatively soft, it is mostly used in active electricity places and temporary electricity places, and it is easy to install, drag and drop and move.
Stranded Disadvantages: The service life is short. Due to the large ratio of outer circle area to cross-sectional area, the oxidation speed is fast. If it is impacted by short-circuit current, the surface will be seriously oxidized after high temperature, and the effective cross-section will be greatly reduced. The safe electricity should be replaced in time.
Although there is a risk of shorting out the battery charger, the risk is small and usually mitigated by the circuitry of the battery charger itself. On the other hand, the short-circuit current of a lead-acid battery installed in a vehicle is large enough that a short circuit may cause a fire or explosion. Therefore, the priority is to avoid short circuits of the vehicle battery, rather than the charger.
Although the term "SAE connector" is commonly used to refer to a two-pin connector, many different connector standards specified by SAE International may also be referenced by this term. Also, while the design of the theme connector is inspired by and based on SAE standards, the connector itself does not have an official SAE name.
After research, we found that there is no specification for SAE2 pin overmolded connectors. SAE (Society of Automotive Engineers) specification J928 covers "Electrical Terminals - Pin and Receptacle Types" and SAE J1239 covers 4, 5 and 8 pin trailer connectors, but there does not appear to be an SAE specification for a 2 pin overmolded configuration.
The SAE connector is a physically self-mating hermaphroditic two-conductor DC connector commonly used in solar and automotive applications. It is named after the Society of Automotive Engineers that created the specification on which this connector is based.
Although the plugs are physically hermaphroditic and any SAE connector can be connected to any other SAE connector, they are not electrically hermaphroditic and care needs to be taken to maintain correct polarity when connecting different plugs to each other.
This connector is often used to impose maintenance costs on vehicle batteries. The polarity of the connector, when installed in a vehicle and connected to the battery, will never cause a short circuit if the exposed terminals touch the vehicle chassis. In most vehicles, this means that the exposed terminal is connected to the negative terminal of the battery. Instead, the positive terminal on the battery charger is exposed to mate with the hidden positive terminal on the vehicle side.
